Title: Double-ended reciprocating compressor
Inventor: IKEDA ISATO
IPC: F04B27/08
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent an increase in frictional resistance of a cylinder bore and a piston even if oil foaming is caused at starting time by arranging hole parts to come and go between a crank chamber and the inside of the cylinder bore according to reciprocating operation of the piston, on an outer peripheral surface of the piston. SOLUTION: When a compression object fluid is sucked in a swash plate chamber from an intake port, lubricating oil contained in the compression object fluid enters through hole parts 28 and 28 provided in shoe receiving parts 9c and 9c of a piston 9, and is discharged in a cylinder bore 8 when the through hole parts 28 and 28 come and go between the swash plate chamber and the cylinder bore 8 accompanying with reciprocating operation of the piston 9. That is, the lubricating oil entering the through hole parts 28 is easily stored in the through hole parts 28 as it is even if oil foaming is caused at starting time. Therefore, when a compressor is operated in a condition where lubricating oil in the compressor runs out by the oil foaming, the lubricating oil entering the through hole parts 28 is discharged in the cylinder bore 8, and acts as lubricating oil.

Title: Driving circuit of electrochromic display element
Inventor: YOKOYAMA MEISOU
IPC: G09G3/19
Filed: 1982-04-10
Abstract: PURPOSE:To make the constitution of an electric power simple and to make capacity considerably small, by enabling the use of one kind of the voltage level for the power source in a driving circuit for a display element by a pair of complementary type transistor constitution and voltage dividing constitution of resistors. CONSTITUTION:The emitter terminals of transistors 10, 11 are coupled to constitute complementary type transistors, and resistors 14, 15 are constituted so as to divide voltage. When a pulse voltage is applied to the base terminals of the TRs 10, 11, the TR 10 goes on and 11 goes off and +Vo voltage is generated at a coupling point A upon attainment of +Vb voltage. When the voltage attains -Vo, the TR 10 goes off and 11 goes on, and the point A falls to an earth level. On the other hand, if the resistors having an equal resistance value are used for the resistors 14, 15, the display is decolored when the display electrode is +Vo/2 and the electrode is colored when -Vo/2. Since a lithium battery of this type is made usable for an source 13 by the above-mentioned method, the constitution of the power source is made simple and the capacity is made extremely small.

Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To enlarge the effective sensitivity range of an image-pickup device by correcting luminance information of an obtained subject according to the distortion of a photoelectric conversion characteristic of an image-pickup device. SOLUTION: A CPU 71 discriminates the value of inputted photographing data D10 and gives an operating instruction SS to a linearizing circuit 851 in a digital processing circuit 85. When the value of the photographing data D10 corresponds to the linear region of the photoelectric conversion characteristic graph of the image-pickup device, the linearizing circuit 851 outputs data D11 of the value as it is, to an image-processing circuit 852. When the value of the input data D10 corresponds to a non-linear region, the value at the time that the photoelectric conversion characteristic graph is assumed to be straight line obtained by extending the straight line of the linear region is adopted as the value of output data D11. Look-up tables for executing correction, corresponding to the distortion of the photoelectric conversion characteristic such as this region are provided for each R, G and B color in the linearizing circuit 851.

Filed: 1991-02-12
Abstract: PURPOSE:To improve constant current control characteristic by reducing a detecting error of an output current detector as much as possible and to stabilize a load current even if an outpost voltage is varied by so providing a bypass circuit that a current for detecting the output voltage does not flow to the detector. CONSTITUTION:A current Ia for detecting an output voltage flows from a connecting point of a diode DA2 of a multivoltage rectifier and a capacitor VCO2 to a connecting point 2 of a diode DA1 and a capacitor C01 through a variable resistor VR03, a resistor R05 and a resistor R01 of the multivoltage rectifier 1. Accordingly, the current Ia for detecting the output voltage does not flow to an output current Ib to be detected by an output current detector 4 thereby to reduce a detecting error of the current Ib by the detector 4 and to accurately control a constant current. If an output voltage is varied, even if the current Ia for detecting the output voltage is varied, it does not exert influence to the detector 4, and a load stability can be enhanced.
