Title: Overwritable magneto-optical recording medium
Inventor: SATOU MASAAKI
IPC: G11B11/10
Filed: 1988-04-28
Abstract: PURPOSE:To attain overwriting only by the modulation of optical intensity without modulating the direction of a recording magnetic field by using the 1st and 2nd layers having respectively specific perpendicular magnetic anisotropy respectively as a recording layer and a recording auxiliary layer to form multilayer structure. CONSTITUTION:The title magneto-optical recording medium has multilayer structure using the 1st layer having the perpendicular magnetic anisotropy as the recording layer and the 2nd layer having different perpendicular magnetic anisotropy as the recording auxiliary layer. When it is defined that either one of upper and lower directions from a layer plane is 'A direction' and the other is 'reverse A direction', only the magnetization of the 2nd layer is allowed to coincide with the 'A direction' by an initial auxiliary magnetic field Hini, up to the time immediately before recording. When a laser beam with a high level irradiates, the 'A direction' magnetization of the 2nd layer is inverted to the 'reverse A direction' by the recording magnetic field Hb, and pits having 'reverse A direction' magnetization (or 'A direction' magnetization) are formed on the 1st layer by the 'reverse A direction' magnetizing action of the 2nd layer. Consequently, overwriting can be attained and recording sensitivity and a C/N can be improved.

Title: Power steering
Inventor: TAKAHASHI SADAHIRO
IPC: B62D6/02
Filed: 1982-06-21
Abstract: PURPOSE:To prevent the steering auxiliary effort of a power steering unit from largely varying, by keeping off a sudden variation in motor revolution at the time of operating a switching device. CONSTITUTION:A comparator circuit 22 outputs a voltage signal commensurate to a new car speed to a duty control circuit 44 via a selector switch 46 even when a change in car speed or in motor revolution due to the variation of load in a motor 13 occurs. For this reason, the control circuit 44 compares both values between a signal outputted by a generator circuit 50 and a signal outputted by the comparator circuit 22 and then outputs a square wave-base current to a transistor 23 whereby a continuous rating current flowing into the motor 13 is controlled by a chopper. Since the motor 13 drives a pump 14 with a revolution commensurate to the car speed irrespective of its load, the quantity of an operating (hydraulic) fluid discharged out of the pump 14 varies with the car speed so that the steering auxiliary effort produced by a power steering unit 12 enjoys dependability on the car speed, thus steering performance is made yet better.

IPC: G05D11/02
Filed: 1981-07-06
Abstract: PURPOSE:To prevent the fluctuation in mixing rate of a mixed liquid, by supplying each liquid to a mixing section with each measuring pump. CONSTITUTION:A control section 12 operates pumps 16-18 so that a mixed liquid level 11 can be kept almost constant, based on a detection signal from mixed liquid level detectors 19 and 20 serving as flow-rate difference detectors for the total flowrate of mixed liquid supplied from measuring pumps 16-18 and the flow rate carried with a mixed liquid carrying pump 3. That is, the total flow rate of the pumps 16-18 is controlled so that the mixing liquid level can be kept almost constant with the control section 12 and the rate of flow of the liquids can be controlled according to the preset program. Thus, the fluctuation in the pressure of the mixing section caused in the discharging process of gas produced in the mixing section can be avoided and the fluctuation in the mixing rate of mixed liquid can be prevented.

Title: Electrochromic display element
Inventor: SAKUTE NOBORU
IPC: G02F1/153
Filed: 1985-05-21
Abstract: PURPOSE:To obtain an ECD which can form a gap part without affecting adversely a display and has good heat resistance by providing a background material to cover the display part and disposing a counter electrode corresponding to the display part in tight contact with the background material. CONSTITUTION:A transparent electrode 2, an electrochromic (EC) material layer 3 and the background material 4 are formed on a transparent substrate successively to a desired pattern to constitute a display electrode substrate 1. The background material 4 laminated on the EC material layer 3 is porous and has affinity with an electrolyte to prevent the intrusion of foam into the space from the counter electrode 7. The background material prevents the counter electrode from being made visible from the front side. A counter substrate 5 has the counter electrode 7 and permits the disposition of the electrolyte in-between. The substrate 1 and the substrate 5 are sealed at the peripheral part after the cell is formed. The electrolyte 9 is filled into the cell and penetrates into the background material and the counter electrode. The electrolyte is held in the space 10 as well. The intrusion of the foam into the space between the background material and the counter electrode is thus obviated and the soiling of the display function is obviated.

Title: Evaporator
Inventor: MOCHIDA YOSHIO
IPC: F28D5/00
Filed: 1979-08-24
Abstract: PURPOSE: To enhance the efficiency and production of a plant by a method wherein heat transmitting pipes are dispersedly arranged in plural shelves so that the heat transmitting pipes are prevented from the effect of the static pressure due to the depth of water immersion, in an evaporator for use in a low thermal heat power generation system.  
     CONSTITUTION: The fluid fed from a pump 14 is led to the uppermost shelf 18 and allowed to flow from left to right, as indicated by the arrow. During flowing in this way, the working fluid exchanges heat with the surface-layer sea water flowing in heat transmitting pipes 16, whereby part of the working fluid is evaporated; the unevaporated portion of the working fluid flows down from the right end of the shelf 18 to the right end of the next shelf 19, and flows toward the left end of the shelf 19, undergoing heat exchange. In this way the working fluid flows down the shelves sequentially. In this case, the liquid surface level in the evaporator is detected by a detector 23 and kept constant. Accordingly, the effect of static pressure due to the depth of immersion is eliminated, the heat transfer on the side of the working fluid outside of the pipes is equal to the sum of the heat transfer by boiling of pool and the heat transfer by forced convection, resulting in an increased coefficient of heat transfer and enhanced efficiency and production.

Title: Memory for ic card
Inventor: SAKAKIBARA KAZUO
IPC: G11C7/00
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain a memory in which both a write operation and a read operation are executed in parallel so as to enhance an execution speed by a method wherein, when a read request comes during the write operation, an interrupt processing operation which reads out data which is written into a memory cell at an address whose read operation is requested is executed. SOLUTION: During the execution of a write operation, a read request is input to a control circuit 5 from the outside. Then, when a data bus 4 is performing operations other than a latch operation, the bus 4 becomes an empty state, and the output of an address latch circuit 9 is stopped. At the same time, address data which is contained in the read request is latched, and data which is written into addresses at a memory cell array 10 on the basis of the address data is read out. That is to say, the execution of the write operation is interrupted once during a read operation, and the execution of the write operation is resumed after the finish of the read operation. In this manner, when the read request comes during the execution of the write operation, the circuit 5 performs an interrupt processing operation which reads out the data written into the address during the read request of the array 10. As a result, both the write operation and the read operation can be executed in parallel, and the execution speed of a memory can be enhanced.
