A cured elastomer golf ball component is made by heating an elastomer compound containing an ethylenically unsaturated elastomer, an ethylenically unsaturated monomer, and first and second free radical initiators to a first crosslinking temperature T.sub.1 in a compression mold and partially crosslinking the elastomer, then heating to a second crosslinking temperature T.sub.2 and curing the elastomer component of the golf ball. Either: (i) the first initiator has a half-life of about 0.2-5 minutes at T.sub.1, the second initiator has a half-life of about 0.2-5 minutes at T.sub.2, and T.sub.2 is higher T.sub.1 by at least about 30° C.; or (ii) the second initiator's one-minute half-life temperature is at least about 30° C. higher than the first initiator's one-minute half-life temperature, T.sub.1 is within about 20° C. of the first initiator's one-minute half-life temperature, and T.sub.2 is within about 20° C. of the second initiator's one-minute half-life temperature.

A rolling bearing retainer which is formed by insert molding a resinous material together with a core member within a mold, in which the core member is embedded within a resin part made of the resinous material and a support area exposure part is provided at a plurality of locations of the resin part for exposing a support area of the core member supported within a cavity of the mold. The resin part includes a ring shaped body and a plurality of support column bodies extending axially from the ring shaped body and defining a pocket for retaining a rolling element therebetween, and the core member is provided with a ring shaped body embedded part and a plurality of support column body embedded parts extending from the ring shaped body embedded part.

The presently disclosed subject matter is directed to a golf ball providing improve play characteristics. The disclosed golf ball includes an outer cover comprising a plurality of divots. The disclosed golf ball further includes a central core comprising one or more lightweight materials, such as aerogel. The combination of the lightweight core and the unique divots enable the golf ball to go farther and straighter when hit by the golfer, thereby providing increased performance.

A handle (14) for a skincare device including a core portion (20) made of recycled polymer material and an outer skin portion (22) made of virgin polymer material. A method of manufacturing such a handle (14). A handheld skincare device including such a handle (14) and a skincare kit including such a handle (14) and at least one razor cartridge.

In one aspect, a seal case is provided for a roller bearing assembly having a central axis. The seal case includes an annular first end section including a rim configured to engage an outer ring, an intermediate section including a radial wall extending inwardly from the first end section and an axial wall extending axially away from the radial wall and the first end section, and an annular second end section extending radially inward from the axial wall of the intermediate section. The seal case further includes an insert of the first end section made of a first material. The first end section and the radial wall of the intermediate section include a second material joined to the insert. The first material of the insert may be selected to provide improved durability and/or to resist expansion and contraction of the first end section caused by changes in temperature.

An electrodeless side-mounted LED string light, a method and an apparatus for manufacturing the same are provided by the disclosure. The electrodeless side-mounted LED string light includes: a first wire and a second wire, a plurality of LED units and a plurality of encapsulants. Each LED unit includes a first surface-mounted LED and a second surface-mounted LED. Luminous surfaces of the first and second surface-mounted LEDs are opposite to each other. The luminous surfaces of the first and second surface-mounted LEDs are perpendicular to an axial direction of the first and second wires. The plurality of encapsulants respectively encapsulants the first and second surface-mounted LEDs therein. With the electrodeless side-mounted LED string light of the disclosure, the utilization rate of the lighting wire of the string light is improved, the utilization rates of raw materials and apparatus are improved, the product quality and manufacturing efficiency are improved.

The present invention relates to a mould half for a mould for transfer moulding encapsulating electronic components mounted on a carrier, where the mould part to support the carrier has a contact surface that includes a primary carrier support surface and a the primary carrier support surface surrounding secondary surface, which surrounding secondary surface is supported by a drive for height adjustment of the secondary surface relative to the height of the primary carrier support surface. Such mould half may be used for transfer moulding of electronic components while relatively easy providing a levelled support for the carrier and compensating for any thickness variations in the carrier. The invention also provides a mould with at least two mould parts and a method for transfer moulding encapsulating electronic components mounted on a carrier using such a mould.

A golf ball manufacturing method includes an inner layer molding step of molding an inner layer that includes an outer surface with a recess, an inner film formation step, after the inner layer molding step, of coating the outer surface of the inner layer with inner film paint to form an inner film, an inner film removal step, after the inner film formation step, of removing the inner film except for a portion thereof covering a surface of the recess to obtain an inner ball that includes the inner layer and the inner film, and a cover layer molding step, after the inner film removal step, of molding a cover layer that includes an outer surface with dimples on an outer circumferential side of the inner ball to obtain a golf ball. The inner layer and inner film are different colors, and the cover layer is transparent or semi-transparent.

An electronic medical device is disclosed here. An exemplary embodiment of the medical device includes a printed circuit board assembly, a protective inner shell surrounding at least a portion of the printed circuit board assembly, and an outer shell surrounding at least a portion of the protective inner shell. The printed circuit board assembly has a printed circuit board, electronic components mounted to the printed circuit board, a battery mounted to the printed circuit board, and an interface compatible with a physiological characteristic sensor component. The protective inner shell is formed by overmolding the printed circuit board assembly with a first material having low pressure and low temperature molding properties. The outer shell is formed by overmolding the protective inner shell with a second material that is different than the first material.
