Title: Current mirror circuit
Inventor: HASHIMOTO MASARU
IPC: H03F3/343
Filed: 1979-02-13
Abstract: PURPOSE:To achieve correct correspondence between the input and output current, by connecting the emitter of the first and second transistors in which the bases are mutually connected to the voltage supply source and connecting the collectors to the emitters of the fourth and third transistors. CONSTITUTION:The emitters of the transistors 1, 2 connecting the bases mutually are respectively connected to the voltage supply source Vcc, and the emitters of the transistors 4, 3 connected to the bases are respectively connected to the collectors. The bases and the collectors of the transistors 2, 4 are connected one another. The input current Iin is fed to the collector of the transistor 4 and the output current Iout is obtained from the collector of the transistor 3. With this constitution, the collector to emitter voltage of the transistor 1 is almost equal to the collector to emitter voltage of the transistor 2, allowing to make equal the collector currents ic1 and ic2 of the transistors 1, 2. Accordingly, the current amplification rate of each transistor is sufficiently greater and the base current is neglected, then ic1=ic4=Iin, ic2=ic3=Iout are obtained and Iin=Iout is made possible.

Title: Air-conditioning device for vehicle
Inventor: NAITOU NOBUYASU
IPC: B60H1/00
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of condensate to a heater core, in an air- conditioning device for a vehicle wherein an internal external air two-layer flow mode is set. SOLUTION: In this air-conditioning device for a vehicle, a partition plate 15b positioned between a vaporizer 12 and a heater core 13 is arranged in an inclined state such that the vaporizer 12 side is positioned below and the heater core 13 side is located above. This constitution excellently suppresses movement of condensate to the heater core 13 side through inclination of the partition plate 15 itself even when condensate adhered on the upper surface of the partition plate 15b is about to be moved toward the heater core 13 side togetherwith a flow of blast air by a partition plate 15b serving as a guide. This constitution prevents the occurrence of a trouble, such as increase of comfortability and worsening of defogging ability of a window glass due to the increase of humidity in a car room occasioned by adhesion of condensate to the heater core 13.

Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of a device by unnecessitating a mass memory for processing concerning an image data compression processing method for compressing source image data by performing multiplex resolution conversion to the source image data. SOLUTION: Source image data expressing a source image are divided 2 into plural blocks, wavelet transformation 3 is performed to block source image data in this block, and plural pieces of image data 4 are provided for each frequency band. Next, respective pieces of image data 4 are quantized 5. Afterwards, respective pieces of image data 4, to which the quantization 5 is performed, are encoded 6.

Abstract: PURPOSE: To economically recover hydrocarbon from a mixed gas comprising air and hydrocarbon vapor, by causing a liquid to absorb the hydrocarbon vapor in an absorption column and flush-evaporating the liquid in two or more stages in a plurality of containers different in degree of vacuum.  
     CONSTITUTION: A mixed gas 1 comprising air and gasoline is brought into vapor liquid contact with lean oil in a first-stage absorption column 2 so that about two thirds of the gasoline vapor are absorbed. The rest of the gasoline vapor is entered together with the air into a second-stage absorption column 3 so that almost all of the rest of the gasoline vapor is caught by lean oil. Rich oil from the first-stage absorption column 2 flows into a rich oil tank 5 and is conducted to a first-stage flush drum 4 by a circulating pump 8 so that the rich oil is flushed. The gasoline vapor is introduced into a gasoline washing column 13 by a vacuum pump 10. Rich oil produced in the second-stage absorption column 3 gathers in a chimney tray 24 and is flushed by a second-stage flush drum 15 so that the gasoline vapor is introduced into the gasoline washing column 13 by other vacuum pump 17.

Title: Hydraulic control device in stepless speed change gear
Inventor: IDE TOORU
IPC: F16H9/18
Filed: 1984-01-30
Abstract: PURPOSE:To prevent a belt from slipping upon kick-down, by exerting a control signal pressure upon the signal load side of a speed change ratio control valve so that the signal load of the above-mentioned speed change ratio control valve is applied to an accelerator opening signal pressure by means of a reaction force signal pressure and the control signal pressure. CONSTITUTION:Upon kick-down of an accelerator a rod 81 in a speed changer ratio control valve 70 is stepped-likely moved by a full stroke in accordance with depression of the accelerator so that a Pitot-pressure on increase acts upon a control plunger 73 while it is regulated by an orifice 85 so that the control plunger moves modelately to gradually increase a spring load. Therefore, no overrun due to shift-down which is caused by an abrupt increase in the spring load is brought about before increase of the Pitot-pressure, and after shift-down to a predetermined speed ratio, shift-up is made along the full-open curve of the accelerator.

Abstract: PURPOSE:To feed a fluid in the energy-saving manner by evaporating heating medium in a heat receiving closed receptacle to contract an expansion receptacle, thereby discharging a feed fluid when a feed fluid of a temperature higher than the atmosphere temperature is fed into the expansion receptacle in the state of expansion. CONSTITUTION:A feed fluid 1 such as warm water or the like in an expansion receptacle 6 is discharged by contraction of the expansion receptacle 6. The full quantity is discharged, and when a discharge control valve 9 is closed, a heat receive and release control valve 12 is separated from a communicating port 7, so that heating medium 2 is cooled and condensed in a radiating chamber 14 to lower the inner pressure in a heat receiving closed receptacle 3.

Abstract: PURPOSE:To decrease the trigger current of a control rectifier element at high temperature and to prevent useless heat and waste power consumption by decreasing a voltage given to a gate of the control rectifier element when the temperature of the control rectifier element is high. CONSTITUTION:The resistance of a limit resistor 5 is selected to give a proper trigger current to a control rectifier element 7 when the temperature of the control rectifier element 7 or its ambient temperature is a prescribed temperature or below. Then a temperature detection section 8 to detect the temperature of the control rectifier element 7 or its ambient temperature is provided in the vicinity of the control rectifier element 7 and the signal representing the detection temperature is given to an AC power supply 1. When the temperature detected by the temperature detection section 8 is a prescribed value or over, the voltage of the AC power supply 1 is lowered and when the prescribed value or below, the voltage is increased. Thus, useless heat and power consumption of the control rectifier element 7 is prevented at a high temperature of the control rectifier element 7 to prevent the temperature rise of the device incorporated with the control rectifier element 7 thereby miniaturizing the device.
