Title: Magnetic recording and reproducing device
Inventor: ARAI KAZUO
IPC: G11B15/467
Filed: 1985-02-19
Abstract: PURPOSE:To search at a high speed the position of a desired magnetic tape without using an exclusive fixed head, by changing the speed of a rotary cylinder in response to the speed of the tape which is driven at a high speed. CONSTITUTION:The conversion coefficient of an F/V converter 6 is changed so as to obtain the rotational number of a rotary cylinder 1 in such a relation where the relative speed between a head cap and a track is set constant according to the driving speed of a magnetic tape 3 set by a drive circuit 23 after a high-speed drive command is supplied to ann input terminal 26 for high-speed drive command. Thus the revolving speed of the cylinder 1 is set at a desired level and at the same time the oscillation frequency of an oscillator 9 is changed a the same rate. The difference of phase is secured between the output of the generator 9 and that of a pulse generator 7 through a phase comparator 8. This phase difference is added with the output of a comparator 6 by an accelerator 10 and applied to a cylinder motor 4 via a drive circuit 11. As a result, the rotational number of the cylinder 1 is set at a level that gives no change to the track direction components of magnetic heads 2a and 2b.

Filed: 1989-02-13
Abstract: PURPOSE:To improve the operability of a data base such as area expansion by preparing the restoring data of a data base by means of a data base system, which is operated for a long time, without stopping transaction service. CONSTITUTION:When a fault occurs, a data base DB updating means 6 disconnects the data base from a multiplexing system, and a DB updating control means 4 activates the DB updating means 6 in order to updates the respective data bases constituting the multiplexing system. When the data base is disconnected, a differential journal means 7 is activated instead of the DB updating means 6. The differential journal means 7 accumulates the fetches data base upodasting information. A difference restoring means 5 restores the data base based on the contents of the differential journal, and when the restoration is completed, the data base is connected to the multiplexing system.

Title: Liquid fuel combustion device
Inventor: KAWASAKI YOSHITAKA
IPC: F23D5/02
Filed: 1978-03-20
Abstract: PURPOSE: To interrupt the fuel supply in a short time without moving the carbureter for quick and sure extinguishment, by forming a narrow fuel passage between the carbureter and the liquid level in the tank.  
     CONSTITUTION: Fuel flows in a tank 2 through a fuel pipe 1 and the fuel level is kept at the B-B' line. A carbureter 4 made of porous ceramic is fixed above the tank 2 to evaporate the fuel. Between the fuel level B-B' and the carbureter 4 is formed a narrow fuel passage 5 by means of a carbureter holder 3 to suck the fuel up to the A-A' level and to the carbureter 4 by virtue of capillarity. When the fuel fed through the fuel pipe 1 is interrupted, the carbureter 4 consumes up all the fuel that can be absorbed from the narrow passage and then the flame goes out. Since  the narrow fuel passage 5 then becomes a capillary tube with a large liber, the  suction level A-A' is separated from the carbureter 4 after the liquid level in the  tank 2 becomes lower than the B-B' line, which interrupts fuel supply to the carbureter 4 and the flame is quickly extinguished.

Filed: 1985-02-20
Abstract: PURPOSE:To simplify the circuit constitution by providing a storage device storing an output of a counter measuring a period or a half period of an FM signal and a ROM using an output of the storage device as an address.

Abstract: PURPOSE:To approximate a picture of high resolution with a small number of bits by discriminating the magnitude of the loworder bit of image data obtained by division processing from the value of a dither threshold and increasing one of the division boundary value within a division range only when the low-order bit is larger. CONSTITUTION:A real number is obtained by dividing input R data by the length of a section by means of a dividing part 3 and an integer is extracted out of the real number by means of an integer extracting part 4. A difference value between the real number and the integer is calculated by means of a difference value calculating part 5 and whether or not the difference value is larger than the relevant threshold value of a dither matrix is discriminated by means of a difference value discriminating part 6. By using the discriminated result, only when the difference value is larger than the relevant threshold value of the dither matrix, one is added to the integer value obtained by the integer extracting part 4 by means of an adding part 7 so as to make a dither value. When the difference value is smaller than the threshold, the integer value as it is obtained by the integer extracting part 4 is made the dither value. The dither value obtained by the adding part 7 is written in a memory 9 by means of a control part 8.
