Patent EP-0276812-A2 (EP)
Inventor: INOUE MASAKAZU
IPC: B02C17/16
Filed: 1988-01-26
Abstract: A dispersing and grinding apparatus disperses and grinds material by the use of a particulate grinding medium. A separator installed at the discharge end of the apparatus separates the processed material from the grinding medium. The separator comprises a stationary stator (4), and a rotatable rotor (11) mounted so that the rim area of the rotor is spaced from and faces the stator to define therebetween a small gap which is large enough to permit the processed material to pass there­through though small enough to prevent the grinding medium from passing therethrough. The rotor (11) has on its underside a plurality of protruding guide portions (15) configured as arc-shaped protru­sions which forcibly guide and disperse the grinding medium tending to collect and concentrate at the rim area of the rotor. By such a construction, the useful life of the rotor is signifi­cantly prolonged because the grinding medium is positively and forcibly guided radially outwardly away from the confronting surfaces of the rotor and stator thereby minimizing wear of the rotor and stator surfaces.

Abstract: A reciprocating piston type refrigerant compressor (1) includes a compressor housing (10) having a cylinder block (101) provided with a plurality of cylinders (32) and a crank chamber (13) adjacent to the cylinder block (101). A piston (33) slides within each cylinder (32) and is reciprocated by a wobble plate (17) driven by a cam rotor (14) mounted on a drive shaft (12). The cam rotor (14) includes an adjustable slant angle in close proximity to the wobble plate (17). Accordingly, the stroke of the pistons (33) within the cylinders (32) can be changed by adjusting the slant angle of the sloping surface. The slant angle of the sloping surface is adjusted in response to the change of pressure in the crank chamber (13). The crank chamber (13) communicates with the suction chamber (35) through a passageway and a valve control mechanism (46) controls the opening and closing of the passageway. Thus, the capacity of the compressor (1) can be adjusted by changing the slant angle of the sloping surface of the slant plate (16) in response to the operation of the valve control mechanism (46).

Abstract: A case for video or audio cassettes composed of an upper housing part and a lower housing part that are foldably joined together by means of a hinge to completely enclose the cassette. At least one elastic element is installed between the upper part and the lower part in such a way that when a closure is disengaged the upper and lower parts are forced apart and the package swings open automatically. In particular, the cassette itself is located in a separate holder that is held between the upper part and the lower part in their common pivot axis, with the elastic elements then operating between this holder and the upper and lower parts. The effect of this is that when the closure, particularly a snap closure, is disengaged, not only do the upper and lower parts swing open automatically, but the holder with the cassette is brought into an angular position that roughly bisects the angle between the upper and lower parts when open. The cassette is thus easy to remove and to replace in the holder.

Abstract: An intermittent suction regulator is disclosed operating from a vacuum system and is used to provide a plurality of pneumatic output signals to a positive pulse device for returning fluids removed from a patient during drainage thereof to clear the removal passageways. The suction regulator or control unit provides two (2) timed output signals, from one (1) intermittent vacuum to atmospheric pressure input. One output signal continually switches from a regulated vacuum signal to an atmospheric pressure signal while the other output signal switches from providing an unregulated vacuum signal to an atmospheric pressure signal. The signals are timed such that both are initially set to provide vacuum signals simultaneously, however there is a predetermined time delay between the time the regulated vacuum output signal switches from vacuum to atmospheric and when the unregulated vacuum output signal switches from vacuum to atmospheric. Both output signals, however, again switch back to their vacuum signals simultaneously after a predetermined cycle time.

Abstract: This invention relates to a ceramic module and to methods for forming protruding, upstanding electrically conducting pins by the selective abrasion of a surface (18) of a multilayered ceramic module (10). An abrasive blasting device (40) is disposed adjacent to the surface (18) for directing a stream of abrasive particles (42) against the surface. The particles (42) strike both metallic conductors (20) and (22) and also the ceramic material of the layer (14). Inasmuch as the ceramic material is relatively hard and brittle as compared to the ductile metallic conductors the abrasive particles (42) abrade away the ceramic layer (14) at a faster rate than the ductile metallic material of the con­ductors (20) and (22). The abrasive particles (42) may be comprised of any suitable abrasive, such as Al₂O₃, SiC or WC. The module may be rotated beneath a nozzle of the grit blasting device, the nozzle being linearly translated above the surface being abraded.

Abstract: The invention relates to a method of making multilayer printed circuit boards from a plurality of core layers each carrying a conductor pattern at least on one side and two location holes, two outer conductive covering layers and perforated adhesive insulating interlayers between each of the core layers and the covering layers (prepregs). To align the conductor patterns on the core layers, the core layers each have two location holes and the interlayers have corresponding holes. Two cores are pulled through the location holes in the core layers and the holes in the interlayers and are cut down to the thickness of the assembly composed of core layers and interlayers. During hot pressing, said cores remain in the location holes and consequently keep the conductor patterns on the core layers aligned with one another and protect the location holes against the possibility of resin flowing out of the prepregs. As many circuit levels as desired can be produced by the method in one hot pressing operation. <IMAGE>
