Patent JP-S6361530-B2 (JP)
IPC: H02K5/124
Filed: 1983-03-01
Abstract: A bearing and seal assembly for use in an electric motor rotor or stator bore about a central shaft. The bearing and seal assembly comprises a drawn aluminum sleeve dipsosed in and secured to the wall of the bore and having opposite end portions projecting beyond the bore wall. A sleeve bearing is press fit in the sleeve with the sleeve press fit or adhesively secured in the bore. An annular seal is press fit in one projecting end portion of the sleeve and is thus held in precise coaxial relationship with the bearing. The opposite projecting end portion of the sleeve provides a seat for an O-ring at a diametrically enlarged portion thereof. A cap in snap engagement with the rotor or stator, or alternatively with the sleeve, engages the O-ring and closes a lubricant chamber surrounding the bearing and within the sleeve. The assembly method includes press fitting of the bearing and seal in the sleeve with the elements mounted on an assembly pin for precise concentricity or coaxial relationship. Alternatively, the sleeve may be press fit in the rotor or stator bore or adhesively secured therein.
Patent JP-H0674721-B2 (JP)
IPC: F01B1/08
Filed: 1984-02-24
Abstract: A compact lightweight engine or pump is constructed having a H-shaped piston, usually double acting. Each end of the piston has extending surfaces which form two moving sidewalls which act with two case sidewalls and a block-shaped head protrusion to define a working chamber with the appropriate top surface of the piston which moves to extract or add energy to the working chamber. Energy is transferred between the piston and a crankshaft by means of a slide block on the crankshaft and the inner surfaces of a pair of parallel walls forming the center of the "H" of the piston, whose opposite surfaces form the piston top surfaces. Through the use of suitable cams and valves, 4-cycle, 2-cylinder equivalent engines can be produced. With suitable porting, baffles, and/or auxillary compression means, 2-cycle engines can also be produced as well as air pumps. The planar walls of the devices maximize displacement while the planar design reduces mechanical stress allowing coatings of heat resistant materials such as ceramic for thermal protection rather than extensive cooling systems.

Patent JP-H0335347-B2 (JP)
IPC: A23L5/41
Filed: 1982-05-14
Abstract: Finely divided, pulverulent carotinoid or retinoid compositions, in which the carotinoid or retinoid essentially has a particle size of less than 0.5 micron, are prepared by a process wherein a carotinoid or retinoid is dissolved in a volatile, water-miscible, organic solvent at from 50 DEG  C. to 200 DEG  C., if necessary under superatmospheric pressure, within the space of less than 10 seconds. The carotinoid is immediately precipitated, in a colloidally disperse form, from the molecularly disperse solution by rapidly mixing the latter with an aqueous solution of a swellable colloid at from 0 DEG C. to 50 DEG  C., and the resulting dispersion is freed from the solvent and the dispersing medium in a conventional manner.
Patent JP-2607879-B2 (JP)
IPC: H04L12/413
Filed: 1987-04-01
Granted: 1997-05-07
Abstract: Method and apparatus suitable for inclusion in an integrated circuit transceiver meeting IEEE 802.3 standards which detects "collisions" so that more than one station will not simultaneously transmit over a network. The method employs a novel three-pole cyclical low-pass filter (20) which attenuates the ac component received over the network to less than 20 mV to allow collision detection within the 900 nanosecond budget allowed by the IEEE standard. A differential operational amplifier (18) receives the signal from the network and a collision reference voltage. The signal generated by the differential amplifier is filtered by the low-pass filter and then coupled to a high-gain comparator (22) which acts as a zero-crossing detector. The comparator generates ECL logic signals representing the occurrence or non-occurrence of a collision. The resulting collision detector operates over a wide range without the need for field "trimming".

Abstract: A rubber-reinforced polymer of a monovinylidene aromatic compound. e.g., styrene, having rubber of two different particle sizes distributed through the polymer matrix and exhibiting a desirable balance of gloss and toughness properties is continuously prepared using mass polymerization techniques. Specifically, the rubber-reinforced polymer is prepared by polymerizing a solution of the rubber and monovinylidene aromatic compound in the presence of a graft promoting initiator, e.g., dibenzoyl peroxide, and at conditions sufficient to form a dispersion comprising a continuous phase of polymer having discrete, rubber particles of a particle size from 0.5 to 1.5 micron dispersed therethrough. Subsequently, additional amounts of rubber are added to the polymerization mixture and polymerization continued at conditions such that the newly added rubber is dispersed throughout the continuous polymer phase as discrete particles having a particle size from 4 to 10 microns. The polymerization is completed and the rubber subsequently crosslinked.
