A rigid crosslinked polymer having effective levels of chain entanglement crosslinking produced by a rapid rate polymerization procedure which comprises the steps of creating a radical flux by providing monomer units with an effective amount of an initiator to initiate polymer growth. dispersing the monomers and initiator to form an aqueous dispersion, and heating the aqueous dispersion to a temperature greater than the ten-hour half-life temperature of the initiator.

A runner cooling block for use in a die casting system comprises a spreader block, a spreader, a bushing block, a sprue bushing and a water jacket. The sprue bushing comprises a sprue channel running through an interior of the sprue bushing and a cooling channel running circumferentially around an exterior surface of the sprue. The sprue bushing, water jacket and bushing block are assembled to allow cooling water to pass through the cooling channel. The spreader block and the bushing block are a...

A thin plate-shaped substrate 21 comprised of a monocrystal is provided with a piezoelectric element 24, and both ends of a movable piece 20 whose one surface is provided with a movable contact 25 are fixed and supported to a base 11. Then, by curving the movable piece 20 via the piezoelectric element 24, the movable contact 25 is brought in and out of contact with a pair of fixed contacts 38 and 39 that face the movable contact. With this arrangement, a subminiature micro-relay having a mechani...

The lower mold which forms the external side of the vehicle wheel is water-cooled by water-cooling pipes. The rib-forming portions of the upper mold which forms the internal side of the vehicle wheel are forcibly air-cooled by the air passages provided along the rib-forming portions. Since water-cooling has better cooling capacity than air-cooling, the molten material inside the cavity between the lower mold and the upper mold is solidified from the external side thereof, and no defects such as ...

An ice making and dispensing machine comprising a chamber for holding a layer of ice particles floating in water held at approximately freezing temperature, a remote dispensing head, an external freezing coil evaporator for freezing water into particulate ice forms, a pump disposed at the surface of the ice-water mixture for moving the mixture to the remote dispensing head, a system of conduits through which the mixture is circulated to the remote dispensing head, a return water pump with approp...

An improved plug for an aperture such as the paint drain hole in an automotive body comprises an integral flat body having two opposed aligning protuberances and two opposed engaging protuberances formed adjacent the edge of the body. At least one engaging protuberance is angled radially outwardly and has sufficient spring qualities to allow a snap mount of the plug into the aperture.

A method and apparatus are provided for a first controlled device, such as a wireless local transmitter that accepts a plurality of digital audio signals and corresponding program information signals converted from a controlled source, such as the encoded digital data provided by a digital data signal source, typically a community antenna television (CATV) cable or direct broadcast satellite, then modulates said digital audio and corresponding program information signals on different carrier fre...

A pouring method and a device in a vacuum sealed process to produce a thin-wall cast by using a mold framing for the a vacuum sealed process, and a as-cast product using the pouring method are provided. The pouring method comprises the steps of: sealingly covering the surface of a pattern plate by a shielding member; placing a mold framing on the shielding member and then putting a fill that does not include any binder in the mold framing; sealingly covering an upper surface of the fill and then...

A new kind of pixel is formed of two floating diffusions of different sizes and different conductivity type. The two floating diffusions have different image characteristics, and hence form a knee-shaped slope.

A line-based digital halftoning technique uses both a wavelet transform and multi-scale dot assignment concepts in which the dots are assigned in a top-down fashion and error diffusion is also adopted to fine tune the halftoned images and compensate for errors generated by the implicit quantization. 1-D processing makes the implementation easy while the top-down multiscale dot assignment can produce a multi-resolution halftoned image, which provides a good approximation of the original in multip...
