Title: Color television system
Inventor: FURUYA REIJI
IPC: F02B75/02
Filed: 1978-11-14
Abstract: PURPOSE: To realize the band compression with application of the interlaced scanning system by shifting the phase of the subcarrier by the half cycle in all for the period of the 1-frame scanning.  
     CONSTITUTION: The luminance signals supplied through terminals 1∼3 plus two color difference signals are multiplied by color encoder 4. In this case, subcarrier entering through terminal 5 receives the phase shift via phase shifter 6 by 1/4 cycle with every field. As a result, the subcarrier component always features the same phase at the same position on the screen, and thus the interlaced scanning can be applied. The signal for the interlaced scanning system is produced by sampler 7 to the output of encoder 4 to be transmitted through terminal 8. At the reception side, the input signals to be supplied to terminal 9 are writtern in sequence into the memory position where frame memory 11 corresponds after the re-sampling given by re-sampler 10 and in synchronization with the sampling frequency of the transmission side. The contents of memory 11 is read out and introduced to color decoder 12 to be converted into the luminance signal and two color difference signals. And these signal are drawn out through terminals 13∼15.

Abstract: PURPOSE:To enable conversion the type of a gas merely through the switching of a gas- type setter, by a method wherein a blower for supplying the air for combustion is installed, and a detector, detecting the pressure or the flow rate of a gas fuel, and the gas-type setter are provided, and a gas proportioning control valve is actuated according to the deviation signal between the detector and the setter. CONSTITUTION:When a gas-type setter 8 is switched by an electric switch according to the gas type to be used and a power source is closed, a blower 4 is run to feed a predetermined combustion air to a mixing part. The gas flowing in through a gas passage 1 flows in a gas proportioning control valve 2, and the gas, producing a flow rate corresponding to a gas type, is fed to a gas nozzle 3. The gas is mixed with the air for combustion in a mixing part 5 to produce an optimum air-fuel ratio, the mixture being burnt at a burner 6. A detector 7 detects a feed pressure (flow rate) to the gas nozzle 3 to compare it with the value of the gas-type setter 8, and the gas proportioning control valve 2 is actuated through a gas proportioning control circuit 10 according to the deviation signal therefrom. This enables completion of reliable conversion of the gas- type through a simple operation, and eliminates the necessity for replacement of a nozzle and regulation of the quantity of a primary air.

Filed: 1983-07-30
Abstract: PURPOSE:To enhance processing efficiency, by rotating a work while grasping and holding the same under pressure by a pair of clamp members each comprising an elastomer having high friction factor. CONSTITUTION:After a work W is grasped and held under pressure by a pair of clamp members 17, a sprocket 29 is rotated by a motor 32 through a chain 33.

Abstract: PROBLEM TO BE SOLVED: To improve a signal reading performance in total and to satisfactorily secure the continuity of dynamic images, particularly in actions reproduction by setting the optimum highest reproducing double speed, in accordance with the grade of a disk recording face and eliminating wasteful switching operation for double reproducing speed. SOLUTION: By means of an AC detection circuit 7, the amplitude value of a drive current is measured which is outputted from a driver 5 to a focus actuator 3, and regarding a reproducing double speed, by a micro-computer 8, it is discriminated whether or not this measured amplitude is an allowable value in the system or whether or not it is less than the set value near the above value. Then, this reproducing double speed is set as the highest speed for a disk presently mounted, thereby prohibiting switching to such a high reproducing double speed as a focusing servo system can be in saturation.

IPC: G06F12/00
Filed: 1989-06-01
Abstract: PURPOSE:To shorten the processing time of a program by previously executing the opening processing of a file before the execution of the program but not by operating a file opening function for the necessary file while the program is executed. CONSTITUTION:The name of the file 2 and control are given to an opening function control means 12 from a file opening means 6 to which the opening of the file 2 is requested from the program 3 and the means 12 operates. The opening function control means 12 retrieves a file control table 41. When the name of the file 2 is registered in the file control table 41, the means 12 gives an instruction not to execute the opening processing for the file 2 to the file opening means 6. When the name of the file 2 is not registered in the file control table 41, the means 12 gives the instruction to execute the opening processing of the file to the file opening means 6 as conventionally. Thus, the processing time of the program is shortened and the performance of a system improves.
