POSITION DETECTION SWITCH AND METHOD FOR MANUFACTURING SAME
A position detection switch is provided with a case having a cylindrical part that has a plurality of ribs on an inner circumferential wall thereof along the axial direction thereof. Accordingly, the strength of the case is increased and running of a molten resin for fixing a substrate disposed on the inside are improved when the molten resin is injected from a long groove of the case. The contact surface area between the ribs and a sheath is increased whereby durability against an external force and temperature variation is increased.
DAMPING BEARING WITH AXIAL PRELOAD
A method of manufacturing a damping device, notably for a steering tie rod, the said device comprising a rod which extends along a main axis and which is intended to be connected to a first mechanical component, a securing portion which surrounds the said rod and which is intended to be connected to a second mechanical component, and a sleeve made of elastomeric material which is arranged between the rod and the fixing bushing so as, through elastic deformation thereof, to allow at least axial movement of the fixing bushing with respect to the rod, in which method the fixing bushing is offset axially with respect to the rod to force the elastic deformation of the sleeve and the introduction of a corresponding preload, then the sleeve is locked so as to keep it, when the device is at rest, in a state of permanent axial elastic deformation and preload.
MEMBER JOINING METHOD AND MEMBER JOINING DEVICE
A member joining method includes: a placement process of arranging a first member and a second member inserted into the first member so that a gap surrounding the second member is provided between the first member and the second member; a filling process of filling a molten resin into the gap and applying pressure to the resin so as to cause at least one member of the first member or the second member to undergo elastic deformation; and a pressure maintaining process of maintaining the pressure until the resin that has been filled into the gap has cured.
Light-weight gear and manufacturing method thereof, manufacturing method of gear train, and robot
A light-weight gear including: an annular tooth portion made of metal; a shaft extending along a central axis of the tooth portion and made of metal; and a coupling element configured to couple the shaft to the tooth portion and made of a resin, in which a joining part between the shaft and the coupling element and a joining part between the tooth portion and the coupling element are provided with irregularities configured to be engaged with one another in a circumferential direction, and corners of the irregularities are rounded to release a stress. Also, provided is a manufacturing method of a light-weight gear including: disposing the tooth portion and the shaft in a mold and injecting a molten resin into a cavity of the mold, thereby simultaneously performing injection molding of the coupling element and joining the coupling element to the tooth portion and the shaft.
ACTIVE NOISE VIBRATION CONTROL APPARATUS AND METHOD FOR MANUFACTURING SAME
An engine mount control apparatus that is an active noise vibration control apparatus according to the present disclosure is characterized by being provided with a housing that has an outer core, an inner core that is disposed inside the outer core, and an electromagnetic coil that is positioned between the outer core and the inner core and by a portion between the outer core and the inner core being filled with a magneto-rheological elastomer containing magnetic particles. The present disclosure enables the maintenance of good static load support performance.
Method to manufacture multi-layer electrical article
A process for making a multilayered article, the process comprising the steps of: (A) Providing a mold comprising: (1) A mold housing comprising (a) at least one injection port, and (b) defining a mold cavity within which are positioned two deformable, pre-molded polymeric sheets; and (2) A removable, hollow core equipped with at least one vent, the removable, hollow core positioned between and space apart from the two polymeric sheets; (B) injecting under high pressure a viscous, crosslinkable, thermoplastic polymer into the mold cavity between the two polymeric sheets and around the removable core, (C) Drawing a vacuum on the mold cavity through both the vent in the mold housing and the vent in the removable, hollow core before, during and/or after the polymer has been injected into the mold; (D) Forming a less than fully cured multilayered article in the mold cavity; and (E) Removing the less than fully cured multilayer article from the mold cavity.
RESIN MOLDING METHOD AND RESIN MOLDING APPARATUS
A resin molding method according to the present invention is a resin molding method that fills a space between an insertion hole provided in a workpiece and a member to be fixed inserted into the insertion hole with resin, the method comprising: injecting a first tablet formed of thermosetting resin having a first temperature into a position of a pot far from the workpiece, the pot pouring the resin into the workpiece and being provided in a molding die, injecting a second tablet formed of thermosetting resin having a second temperature higher than the first temperature into a position of the pot close to the workpiece; pouring the thermosetting resin into the insertion hole of the workpiece in an order of the second tablet and the first tablet by a plunger that slides in the pot.
Materials, methods and devices for joining lines
A hand-held device for joining fishing line segments of monofilament, fluorocarbon, and/or braid lines of similar or differing sizes or combinations or securing hooks or other components to at least one line. The device includes an encasement for orienting the fishing line segments in a closed chamber in close, non-contacting orientation. A material is injected into the closed chamber to encase the lines. This material can be adhesive material or a flowable polymer material having a melting temperature lower than the line segments to be bonded. A pre-formed, flexible polymer sheath is used to retain the line segments in the chamber. A heater heats the polymer sheath within the encasement to allow the polymer to flow and encase the line segments without melting the line segments. Bonding of the line segments can be achieved without melting, abrading, compressing, or impairing the integrity the line segment(s) to be encased.
Vehicle door and production of the same
The invention relates to a vehicle door which comprises at least one support part of plastics material and at least two frame parts, wherein the frame parts are connected to one another by way of connection nodes, wherein the connection nodes are able to be produced by insert-moulding, wherein the support part of the same plastics material is simultaneously linked to the connection node.
Wheel of a single or double caster for furniture
A wheel for a single or double caster for furniture or hospital beds or medical equipment, the wheel comprising: a rim; a tire; and a wheel bearing centrally arranged in the rim, wherein a running surface of the tire envelops the rim, and wherein the running surface of the tire includes a plurality of bonded spokes which are at least in contact the wheel bearing. The wheel is producible in a simple manner with short cycle times while having good thermal conductivity.
