A flexible elastomeric grip for a golf club has an elastomeric insert extending fully through the wall of the tubular grip and exposed on its exterior surface. The insert is comprised of a material having greater stiffness than the body material for enhancing gripability.

A flashlight can include a flashlight shaft, a grip overmolded on the flashlight shaft, and a light element connected to the flashlight shaft. The flashlight shaft can have a circumferential grip recess bounded by two raised portions. The grip recess can have a surface lower than the two raised portions around a circumference of the shaft. The shaft can be integrally formed as a single piece. The grip can be overmolded into the grip recess, such that the grip covers the surface of the grip recess and is bounded by the two raised portions. The grip can be formed of a material that is insufficiently flexible to pass over the two raised portions without damage.

Various processes and compositions for producing wax or wax-like shells for electric candles and other lighting devices are described. Preferred processes utilize injection molding to produce the shells from a mixture of materials. The materials may be compounded before being heated and injected.

An optical fiber re-coating device of the invention includes an optical fiber coater that includes: a pair of glass members having grooves formed thereon; and two bases on which the respective glass members are provided, wherein at least one of the paired glass members has a cross section in a direction vertical to a mounting surface of the bases, the cross section is formed in a trapezoidal shape, the groove is provided on a short side of the trapezoidal shape, and an inclined surface of the glass member including an inclined side of the trapezoidal shape is pressed, and the glass member is thereby fixed to the base.

A control valve includes a housing, a valve body arranged in a valve chamber of the housing, and a support portion slidably supporting an outer surface of the valve body in the valve chamber. The valve body is slidable on the support portion between an open position at which an outlet port is open and a closed position at which a seat surface of the valve body closes the outlet port. The valve body includes a skin layer forming the outer surface of the valve body, and a core layer under the skin layer. The outer surface of the valve body, other than the seat surface and a slidable area, includes a core exposed portion where the core layer is exposed without being covered with the skin layer.

A control valve includes a housing, a valve body arranged in a valve chamber of the housing, and a support member fixed to the housing and supporting the valve body in the valve chamber. The valve body has a tubular shape into which the support member is inserted, and the valve body is slidable on the support member between a first position to close an inlet passage and a second position to close a drain passage. The valve body includes a skin layer forming an outer surface of the valve body, and a core layer under the skin layer. The outer surface of the valve body includes a core exposed portion where the core layer is exposed without being covered with the skin layer.

A needle-equipped syringe reduces an inclination of a needle by reducing an inclination of a core pin when insert molding is performed. The needle-equipped syringe includes a barrel formed using a resin and having a cylindrical body, a nozzle part provided at a distal end of the body, and an opening part provided at a proximal end of the body; and an injection needle held by the nozzle part. The injection needle and the barrel are integrally molded so that an axis of the injection needle is substantially parallel to an axis of the body. The body has a thick part and a thin part located at a proximal end of the body at opposing positions across the axis of the body. At the proximal end of the body, an axis of an inner surface of the body is offset from an axis of an outer surface of the body.

The purpose of the present invention is to provide a container holder with which it is possible to hold a container in a non-tilted manner and which has a draft angle for smoothly extracting a die used when manufacturing the container holder through injection-molding. A hole in which the container holder according to the present invention accommodates a container has a first wall section and a second wall section, the first wall section having a shape such that the hole widens from an opening section toward a bottom section, and the second wall section having a shape such that the hole widens from the bottom section toward the opening section (refer to FIG. 4).

A process for molding one or more bottle preforms, wherein molten plastic is injected into at least one molding cavity; and wherein air is drawn from the at least one molding cavity, through at least one channel for the air to pass from the at least one molding cavity towards the outside of the molding device, by means of suction means; and apparatus and device for performing such a process.

Provided is a plunger including: a plunger body; a first surface configured to come into contact with an inner peripheral surface of the cylindrical member; a second surface disposed on a base end side relative to the first surface, the second surface having an outer diameter that is smaller than that of the first surface; an outer stepped surface disposed between the first surface and the second surface; a first housing disposed in an area at least partly corresponding to the second surface in the recess, the first housing being provided for housing a tip part of the pin; a second housing disposed on the base end side relative to the first housing, the second housing having an inner diameter that is smaller than a largest inner diameter of the first housing; and an inner stepped surface disposed between the first housing and the second housing.
