Title: Static pressure fluid bearing
Inventor: IWASAKI KENICHI
IPC: F16C32/06
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To remarkably improve the exhausting efficiency and to allow a static pressure fluid bearing to sufficiently operate even with double exhaust channels and under the ultra high vacuum environment of above a predetermined value, by inclining an inner wall of at least an air supplying channel with respect to one of guide surfaces at a specific angle. SOLUTION: The compressed fluid supplied to a clearance T between a first guide surface 2 and a second guide surface 4 is recovered by a suction pump by means of double exhaust channels 7, 8 formed around an air supply hole 6 to prevent the fluid from leaking from the clearance T. As an inner wall of the exhaust channel 7 positioned at least inside is inclined to the second guide surface 4 at an angle a of 40-65 degrees, most of fluid is recovered by the exhaust channel 7, and the remained fluid is recovered by an outside exhaust channel 8, which remarkably reduces the fluid amount leaking from the clearance T. A static pressure fluid bearing can be operated without impairing a vacuum degree even under the ultra high vacuum environment of over 1×10-5 Torr.

Title: Recovery device of ash
Inventor: KAWAHARA YUUZOU
IPC: F23J1/02
Filed: 1983-09-29
Abstract: PURPOSE:To extract and recover automatically ash to be produced by a boiler in a particulate state without suspending operation of a furnace, by atomizing fluid ash by an ejector. CONSTITUTION:Fluid burnt ash 2 in the inside of a combuction chamber 1 is passed through an ash lead-out path 12 and led into a suction side of an ejector 6. Gas such as air, vapor and various kinds of exhaust gas to be supplied as a driving fluid of the ejector 6 from a supply source such as a blower is erupted at high speed by passing through an erupting nozzle 5 from a gas lead-in pipe 4. As molten ash led out and sucked up to the ejector 6 is blown off by high speed gas erupting from the nozzle 5 and cooled at the same time, the ash is atomized and discharged from the ejector 6 along with the gas. The gas containing the atomized ash is led into a separator 7 and the ash is recovered through separation. As for the separator 7, a centrifugal type one is desirable. The atomized ash accumulated on the bottom of the separator is taken out from an ash hopper 10.

Title: Sheet feeding device
Inventor: SAITO NAOMASA
IPC: B65H1/26
Filed: 1987-07-18
Abstract: PURPOSE:To take out sheets left in a feed roller part when cassette is replaced, by furnishing a sheet returning member rising and falling by its own weight adjoining to a roller which feeds sheets from an accommodating cassette while distributing one by one. CONSTITUTION:Sheet returning rings 51 having a center hole 51 a little larger than the dia. of a shaft 11 of a roller 1 are installed on both sides of a feed roller 1. In the sheet feeding condition as shown in attached illustration, the sheets A accommodated in a cassette 4 are distributed by the feed roller 1 and friction member 21 and fed toward a guide plate 6. When the cassette 4 is drawn out, a lever 3 rotates round a fulcrum 33 in the direction of arrow C to slacken a spring 23, and another lever 2 rotates round a fulcrum 22 in the direction of arrow b. Now the friction member 21 does not press the sheet returning ring 5 and feed roller 1 any more, and the ring 5 falls by its own weight. Also the sheet pinched by the roller 1 and friction member 21 is drawn out together with the cassette 4. This facilitates cassette replacement during feed of sheets.

Title: Driving method of switching circuit
Inventor: IWAMURA MASAHIRO
IPC: H03K17/62
Filed: 1982-10-15
Abstract: PURPOSE:To increase the number of switching circuits driven at the same time without requiring increase in package grounding pins by splitting the switching circuit into plural groups and adopting different switching timing to each group. CONSTITUTION:Data input signals A1-An are given respectively to the switching circuits 70-1-70-n of the 1st group, the circuits are on/off-controlled with the 1st switching control signal GA, and the 2nd and the 3rd groups are controlled similarly by signals GB and GC. Since a common impedance 40 is formed with bonding wires and package pins connected externally to the internal ground, a noise voltage is generated across the common impedance at on/off control, but the generation takes place spearately because the phase of the signals GA, GB, GC is different, and the number of switch circuits possible for simultaneous drive is increased in comparison with the case without grouping. Thus, the decrease in the common impedance due to increase in the grounding pins is avoided.
