Title: Control circuit for inverter
Inventor: KOSHIN HIROAKI
IPC: H02M7/537
Filed: 1987-07-15
Abstract: PURPOSE:To prevent a MOSFET from being damaged, by detecting voltage at both ends of a current detecting resistor, and by turning the MOSFET OFF regardless of input signal in a period when the drain current of the MOSFET exceeds a specified value. CONSTITUTION:Two serial circuits connecting two MOSFETs Q1-Q4 in series to a DC power source Vin are arranged in parallel with each other, and to a space between the connecting points of the FETs, and an inductive load L is connected, to constitute a full-bridge type inverter. Into the negative pole side of the DC power source Vin, a current detecting resistor R1 is inserted, and a voltage detector E is set up to defect that voltage at both ends comes to specified voltage or higher. Besides, the FETs Q1-Q4 are ON/OFF-controlled according to input signals V1-V4, and gate circuits G1-G4 for turning the FETs OFF with the output of the voltage detector E regardless of an input signal state are arranged. As a result, by turning them OFF in a period when the voltage at both ends of said resistor R1 exceeds a specified value, drain current can be prevented from being excessive.

IPC: F02D41/06
Filed: 1984-08-24
Abstract: PURPOSE:To keep an air-fuel ratio in the desired value as well as to prevent an exhaust gas component from getting worse, by calculating a suction air quantity compensation factor, compensating a rising portion for pressure in a surge tank according to the time elapsed after starting or accelerating, while compenstaing the air quantity for decrement. CONSTITUTION:The air taken in by way of an air cleaner 12, after being metered by an air flow meter 14, is drawn in a combustion chamber 10A by suction together with fuel to be spouted out of an injector 20 installed in a suction manifold 19 via a suction pipe 15, a throttle valve 16 and a surge tank 18. An electronic fuel-injection controller 26 calculates an injection quantity on the basis of a suction air quantity or the like out of the air flow meter 14. And, in time of starting or accelerating, it calculates a decrement compensation factor for compensating a rising portion for pressure inside the surge tank and also calculates the injection quantity with the suction air quantity after compensation. With this constitution, in time of starting, an air-fuel ratio is preventing from being overrich and, what is more, an exhaust gas component is prevented from getting worse.

Filed: 1988-07-15
Abstract: PURPOSE:To easily detect abnormality of a gapless arrester by providing an infrared-ray sensor, or a deterioration detecting means which is formed by sticking a metallic foil to a thin plastic plate having a slit. CONSTITUTION:A deterioration detecting means 18 is attached by providing an insulating plate 16 on the lower part of a bursting hole 13 provided on the lower metallic fixture 12 of a gapless arrester. The deterioration detecting means 18 is constituted by sticking a metallic coil 20 such as an aluminum foil, etc., to a plastic plate 19 provided with a slit 21 in the center so as to close up the slit 21, drawing a signal cable 22 for detecting its cutting to both ends of the metallic foil 20 and connecting it to a terminal box. In this state, the deterioration is detected electrically due to a fact that high pressure gas generated by deterioration or a rupture of the gapless arrester cuts the metallic foil 20. In such a way, abnormality is detected easily without stopping a line or removing the gapless arrester, and a remote centralized control can be executed.

Title: Hard copy device
Inventor: MORI KAZUO
IPC: H04N5/76
Filed: 1987-07-15
Abstract: PURPOSE:To prevent such error that the same image is photographed twice by subtracting an image to be photographed and its previous image and giving the alarm whenever a subtracted result is less than a threshold. CONSTITUTION:When image data on an image 5a being a 1st frame is written in a memory 16, a processor 17 will not operate because no object to be subtracted exists at that time. When image data on an image 5b being a 2nd frame is written in the memory 16, a controller 16 has the processor 17 fetch the image data on said two images from the memory 16. Based on that, the processor 17 substrates the image data on the 1st and 2nd frames. Similarly 3rd and fourth frames are substrated, and the result is transmitted to the controller 15 from the processor 17. Based on the result, the controller 15 checks substracted values, and rings a buzzer 21 whenever they are unsatisfactory.

IPC: H04J3/06
Filed: 1985-08-12
Abstract: PURPOSE:To decrease a circuit scale and to attain a high circuit integration by attaining an operation separating a high speed signal section and a low speed signal section. CONSTITUTION:A clock extraction circuit 36 at the reception side 3 extracts a high speed clock, which is frequency-divided by a counter 32 to obtain a low speed clock. The low speed clock fL is used to separate a high speed data signal by a demultiplexer 31. A control signal channel detector 33 detects one channel including a frame synchronizing signal among separated signals to check on which order of line in the (n+1) channels a control signal such as a frame synchronizing signal is given. Since the next channel to the detected channel is CH1, a channel sequential switching device 35 is subjected to switching control to connect the output of the demultiplexer 31 to the 1st output line of the output PCM signal line 34.

Inventor: HIGUCHI TADASHI
IPC: H04N17/04
Filed: 1994-07-28
Abstract: PURPOSE:To adjust a television receiver with a laterally long side and to measure distortion quickly and accurately. CONSTITUTION:The device is made up of a circuit generating an image having an expansion ratio reverse to image compression for upper and lower peripheral parts in the wide zoom mode of a television receiver with a laterally long side and a circuit generating an image having an expansion ratio reverse to image compression for left and right peripheral parts in the full mode. The image signal generated by the circuits is given to the television receiver with a laterally long a side, on which images at a uniform interval are displayed and the image is picked up by a television camera 7 to make adjustment and to measure distortion. Or in place of the image generating circuits, a computer is used to analyze a television image pickup image and to display images at a uniform interval automatically as the image generating method. Thus, it is avoided that the images displayed at a ununiform interval are used for adjustment or distortion measurement images and then quick and accurate adjustment and measurement are conducted.
