A novel pressure control system provided for maintaining a constant predetermined excess pressure in a fluid dispensing container comprises a high-pressure plastic vessel having an inner chamber and an upper open end, and a pressure control device with a valve, which pressure control device is mounted on the upper open end of the high-pressure vessel, whereas a passageway is provided from the inner chamber to the outside, which is controlled by the valve, wherein the vessel is substantially cylindrical.

The upper part of the vessel has a spherical dome with a cylindrical insert provided for receiving the pressure control device and the lower end of the vessel has an open end, which is closed by a ring-shaped closure.

A laser welded structure is formed by laser welding together a resin molded body formed from a thermoplastic polymer alloy containing a crystalline resin and an amorphous resin and a metal body made of a metal. A glass transition temperature of the amorphous resin is lower than a melting start temperature of the crystalline resin.

An air conditioning piping system of the disclosure includes a refrigerant pipe made of a plastic material and configured to provide a fluid flow between components constituting an air conditioning system; at least one connection flange made of the plastic material and configured to provide a connection between the refrigerant pipe and components constituting the air conditioner system; and at least one charging port made of the plastic material and having a charging valve configured to inject a refrigerant into the refrigerant pipe.

Electronic components are often assembled using robotic equipment, such as pick-and-place machines, that is not optimized for components such as ultra-thin semiconductor bare dice. Selective laser-assisted die transfer is described based on the unique blistering behavior of a multilayer dynamic release layer when irradiated by low energy focused laser pulse(s) in which the blister creates translation of the article being placed. Accurate placement results are provided with negligible lateral and angular displacement.

The present invention relates to a motor vehicle luminous device including at least one first portion that is transparent to at least one laser beam, the portion having at least one first polymer material, and at least one second portion that absorbs the laser beam and is transparent to at least some of the visible spectrum, including at least one second polymer material, the second portion being laser welded to the first portion.

To provide a balloon catheter and an apparatus and method for manufacturing the balloon catheter, whereby the degree of welding can be appropriately adjusted and the balloon catheter can be formed so as to have a desired surface profile suitable for various uses including medical use. With a shaft 14 inserted through a catheter tube 30a inserted into an end portion 28b of a balloon and also with a pressure tube 32a fitted around a welding section where the end portion 28b of the balloon 28 is lapped over the catheter tube 30a, the shaft 14 is heated by emitting laser light from a laser radiation unit 8 to the welding section while the shaft 14 is rotated by a chuck, to weld the welding section.

A method for manufacturing a radar cover which covers a radar unit configured to detect surrounding conditions of a vehicle includes: preparing a base having a recessed portion formed of a transparent layer and comprising a colored layer stacked on a portion other than the recessed portion, and a shining member comprising a basal portion including a shining layer on a surface thereof and an edge portion; arranging the base and the shining member such that the edge portion of the shining member and the colored layer of the base are in contact with each other and the shining layer of the basal portion and the recessed portion face each other; and fixing the edge portion and the colored layer to each other.

An electronically commutated direct current motor with a housing, a housing cover, a bearing shield, a rotor and a stator, wherein the rotor includes a shaft and a permanent magnet and the stator consists of single terminals, which are provided with terminal insulation. The direct current motor ensures a space-saving construction connection of motor components or components with the housing of the electronic commutated direct current motor, conforming to its class, wherein additional connections or sealing elements are not required, wherein a firm and sealed connection can be manufactured upon demand and an easy integration of other functions and interfaces is possible.

A joining method for joining a resin member and a metal member by heating is provided. Joining of the resin member and metal member is performed by heating a joining interface of the resin member and metal member to a temperature in a range of equal to or higher than a decomposition temperature of the resin member and lower than a temperature at which gas bubbles are generated in the resin member and by cooling a surface of the resin member on the opposite side from a joining surface thereof with the metal member to a temperature that is lower than the melting point of the resin member.

A laminate of the present invention includes a first member which contains a thermoplastic polymer and through which laser light is transmitted and a second member which contains a thermoplastic polymer and absorbs laser light, wherein the first member is directly bonded to the second member, and A represented by the formula 1: A=−9×D+Wa−45 is more than zero. D represents a distance between a Hansen solubility parameter of the thermoplastic polymer of the first member and a Hansen solubility parameter of the thermoplastic polymer of the second member, and Wa represents work of adhesion calculated from each surface free energy of the first member and the second member. Such a first member and a second member are firmly bonded to each other without using a bonding sheet.
