Title: Load sensing circuit
Inventor: AKITA YOSHISUKE
IPC: F04B49/00
Filed: 1982-06-19
Abstract: PURPOSE:To maintain respondency in flow control and enable absorbing surge pressure at a load limit by not allowing a peak-cut valve to function during a flow rate control period and by allowing the peak-out valve to function when a load reaches a limit value. CONSTITUTION:In a load sensing circuit in which both a relief valve 4 that relieves the discharge rate of a pump 1 when load side hydraulic pressure P2 reaches a prescribed value and a peak-cut valve 5 that absorbs the surge of pump side hydraulic pressure P1 are provided, when the flow rate is reduced by means of an electromagnetic flow rate control valve 2, a check valve 10 is kept closed and the relief valve 4 does not open for the pressure below the prescribed pressure even if the load side hydraulic pressure P2is lowered. As a result, the peak- cut valve does not function because its low pressure side pilot hydraulic pressure is not lowered. But when the load reaches a limit value, the load side hydraulic pressure P2 increases rapidly. And if the relief valve 4 starts leaking, the hydraulic pressure at point (e) decreases, opening the peak-cut valve 5 to absorb the surge pressure.

Title: Adapter for recording and reproducing
Inventor: TERAO MASATOSHI
IPC: H04N5/225
Filed: 1989-04-27
Abstract: PURPOSE:To execute electric connection with an optical equipment by simple operation by providing an interlock mechanism to link a connector cover to a hole part cover and a connector for recording information provided in the main body of an adapter to connect the connector for recording information output of the loaded optical equipment when the two covers are opened. CONSTITUTION:By loading the optical equipment on a loading panel 27, a con nector cover 63 is linked to a hole part cover 34. When the loading panel 27 is fluctuated in a state that the optical equipment is loaded, the hole part cover 34 releases the through hole part of the loading panel 27 and simultaneously, the connector cover 63 is interlocked to the hole part cover 34. Then, the connec tor front surface of the optical equipment is opened. When the loading panel 27 is further fluctuated, a connector 62 of the optical equipment and a connector 26 of the adapter are connected through the through hole part of the opened loading panel 27. By fluctuating the loading panel so as to be returned to an original position, the connector 62 of the optical equipment and the connector 26 of the adapter are separated and afterwards moved backward so that the hole part cover 34 and connector cover 63 can be opened. Thus, the adapter and optical equipment can be easily linked.

CONSTITUTION:Reverse rotation of the drive motor 5 actuated by a jam signal puts a worm wheel 8 in rotation in the direction of the dotted arrow to permit a sheet bunch placing plate 1 to sink with the aid of a wire 14 and a pulley 12 to rotate in the direction of the dotted arrow, and then the rotation of gear 45, idle gears 46, 47, gear 48, shaft 28 and one-way clutch 29 in directions as shown by respective arrows will rotate the lower separator roller 26 in the direction of the arrow, i.e. in the reverse direction to paper feeding. Consequently, the upper separator roller 25 rotates counterclockwise. Accordingly, the sheet S is returned to the paper feeder box 2 off from the rollers 25, 26. Thus, according to this constitution, a sheet in jam can be taken away automatically to assure prevention of damage to the sheet.

IPC: H03M1/66
Filed: 1988-04-28
Abstract: PURPOSE:To minimize the degradation of linearity accuracy by constructing an input element for a power source which is used as a reference current in a block composed of other plural current sources. CONSTITUTION:When using plural strings of A/D converters DAC as DA1-3, a dedicated transistor TRC1 for generating reference voltage is provided and a TRB1 for a reference current source is provided for each DAC string. In such a case, each source terminal is connected to the same power source line on each string by a current mirror circuit composed of TRC1 and B1 and when source voltage conditions are made equal, voltages between gates and sources are made equal. Thus, noise filter effect is obtained by wiring resistances and capacities R11, C11-R33, C33 who are parasitizing reference voltage VREF signal lines. Consequently, the degradation of a linearity characteristic based on the difference in source common power source voltage caused mainly by the wiring resistances can be minimized.

Abstract: PURPOSE: To obtain titled resin having excellent surface gloss, weather resistance, heat resistance, impact resistance, etc., by graft polymerizing an alkenyl aromatic monomer and an unsaturated dicarboxylic acid anhydride-containing monomer component in the presence of an ehylene-propylene rubber.  
     CONSTITUTION: A thermoplastic resin is produced by dissolving the total ethylene- propylene rubber in a monomer consisting mainly of an alkenyl aromatic monomer, e.g., styrene, if necessary, adding a solvent which dissolves the rubber, continuously adding an unsaturated dicarboxylic acid anhydride, e.g., maleic anhydride, so that the ratio to the anhydride is kept substantially constant during the polymerization, and copolymerizing the reaction mixture so that the total resin composition obtained by the polymerization contains 20W30wt% rubber and 5W35wt% unsaturated dicarboxylic acid anhydride. Thus, an impact-resistant resin having excellent resistance to heat and weather, and good surface gloss and appearance is obtained by polymerizing so as to reduce the amount of alternating chains of the alkenyl aromatic monomer and the unsaturated dicarboxylic acid anhydride.

Title: Avalanche photodiode
Inventor: ITOU MASANORI
IPC: H01L31/10
Filed: 1978-09-01
Abstract: PURPOSE: To obtain an avalanche photodiode of low noise and high multiplication by several multiplication regions.  
     CONSTITUTION: A π layer of the thickness of about 35 μm is allowed to grow epitaxially on a P +  substrate of Si, then ions are injected on the surface to make P layers P 1 , P 2 , N +  layers are diffused on the surface to make a pn junction J. When weak electric field is acted, a 1st carrier multiplication region Ab characterized by a low multiplication rate and an excessively low noise factor and a p-n junction are formed, while when heavy electric field is acted a 2nd carrier multiplication region Aa with a high multiplication rate and an excessively high noise factor is formed. Since an excessive noise factor F 1 (M 1 ) of the region Ab is smaller than a factor F 2 (M 2 ) of the region Aa, the noise factor F of the whole system can be nearly equal to the factor F 1  for a large multiplication rate M 1  low noise can be obtained and the multiplication rate M also can be increased because M=M 1 ×M 2 . In this way low noise and high multiplication can be achieved.
