Filed: 1994-09-16
Abstract: PURPOSE: To provide an ice heat regenerative air conditioner capable of suppressing the increase of consumed current during an operation using heat regenerative air-cooling and reducing electricity rate by efficiently controlling the operation using the heat regenerative air-cooling while a peak shift operation is conducted. CONSTITUTION: An ice heat regenerative air conditioner has a first refrigerant driving device 11, a first refrigerating cycle using air as a heat source and a second refrigerant driving device 22, and a second refrigerating cycle using heat stored in a heat storage tank 51.

Abstract: PROBLEM TO BE SOLVED: To reduce a distributed-constant like resistance value of a gate electrode and increase switching speed and transfer efficiency by forming a plurality of source regions and drain regions, each surrounded by the gate electrode, connected in parallel to each other. SOLUTION: A plurality of source regions 1a and drain regions 1b, each surrounded with a gate electrode 2, are connected in parallel to each other, thus forming source and drain electrodes of a transistor T1. The gate electrode 2 is formed in a grid, where three or more drain regions 1b or source regions 1a are formed around each of the source region 1a or drain region 1b. The source regions 1a of the transistor T1 respectively have a diffusion region 1c for connecting a well region 6, formed in a semiconductor substrate to a predetermined potential. This easily reduces the distributed-constant like resistance of the gate electrode 2 at a position away from connection with a metal wiring layer 3b with a resistance lower than that of a polysilicon layer.

Title: Fast fourier transform arithmetic circuit
Inventor: KATO RYOHEI
IPC: G06F17/14
Filed: 1984-10-24
Abstract: PURPOSE:To shorten the operation time and increase the rate of in-taking of the input data column by taking-in the input data column in two data memories of real number part and imaginary number part alternately when the input column is of real number data only. CONSTITUTION:The operation of the real number part is performed by a data memory 22, a multiplier circuit 24, and an adder-subtractor 25, and that of the imaginary number part is done by a data memory 23, a multiplier circuit 26, and an adder-subtractor 27. A fast fourier transform arithmetic circuit needs at least four clocks in order to perform the butterfly operation of the input data constituted only by the real number part. Therefore, when the input data column is of real number part only, the data is so controlled as to be taken-in by memories 22 and 23 alternately. In this manner even if the frequency of the internal clock is 1/2 of that of the clock that controls the entire system, all the data columns can be stored in the memories 22 and 23 without lowering transmission time to 1/2. Also, two pieces of data can be transmitted to the arithmetic circuit by one clock.

Filed: 1988-09-07
Abstract: PURPOSE:To inhibit the alteration of an LSI by detecting a fact that the main body case of the LSI is opened via a sensor to turn on a switching circuit with the detection output of the sensor and applying a destructive battery to the LSI. CONSTITUTION:When a main body case of an LSI 4 is opened for alteration of the memory contents of the LSI 4, a solar battery 8 is irradiated by the light and generates the electromotive force. Thus both transistors Tr1 and Tr2 of a switching circuit 10 are turned on, and the collector voltage of both transistors have low levels. Then the gate voltage levels of the MOS transistors 6a and 6b are inverted by an inverter 12 into high levels. Thus both MOS transistors are turned off. While the gate voltage of the MOS transistors 14a and 14b of the circuit 10 are set at low levels. Thus both 14a and 14b are turned on. As a result, the LSI is destroyed.

Title: High pressure fuel carburetor for diesel engine and combustion method
Inventor: TANIGAWA HIROYASU
IPC: F02B3/06
Filed: 1993-07-15
Abstract: PURPOSE:To prevent the production of nitrogen oxide and eliminate incomplete combustion by providing a nitrogen gas cylinder, and gasifying fuel with the content inside the cylinder. CONSTITUTION:A high pressure fuel carburetor 24b is connected to a nitrogen gas cylinder via a high pressure gas passage 14. High pressure reversely whirling gas is jetted from a spiral chamber 15 to vaporize fuel jetted simultaneously to be jetted in reverse whirling into a combustion chamber through injection windows 19 of a vaporizing chamber 26. The bottom surface of an outer cylinder 17 is formed into a conical shape corresponding to injection ports 18 of various angles except for the radial and axial directions. Injected oil particles injected from the injection port 18 for injecting the fuel therethrough at various angles are vaporized by simultaneously jetting high pressure reversely whirling gas from the spiral chamber 15 and jetted in reverse whirling into the combustion chamber through the suitable number of the injection windows 19. Consequently, since the fuel which is gradually rotation- accelerated to scatter into the oxygen atmosphere by its own centrifugal force is subjected to lean combustion in sequence, combustion is started after diffusion, thus restraining the production of nitrogen oxide and generation of black smoke.

Abstract: PURPOSE:To absorb a shock produced at the time of coupling an armature to a rotor by connecting the armature to which driving force from the rotor is transmitted and a coupling member with spring members adapted to elastically displace in the rotating directions of the armature and the coupling member. CONSTITUTION:When an electric current is applied to an exciting coil 10, a magnetic circuit is formed among a field core 11, a rotor 5 and an armature 2, and the armature 2 is attracted to the rotor 5 against a releasing plate spring 1.
