Title: Transless type switching constant voltage power unit
Inventor: NOZU MIKIO
IPC: G05F5/00
Filed: 1978-12-04
Abstract: PURPOSE: To obtain a compact and light-weight constant voltage power unit of transless which can set the free output voltage by generating the gate signal through the comparison between the voltage passed with the time limit of the commercial power source and the free reference voltage and thus giving the control to the CRT.  
     CONSTITUTION: The voltage obtained from the commercial power source is controlled at time control part 16, and the voltage passed for the time controlled is compared with the free reference voltage at reference voltage comparison part 17. When the voltage passed through part 16, becomes lower than the reference voltage, the gate signal is generated to be applied to the CRT of current pass control part 18. Thus the current path is controlled for the commercial power source. The output current at part 18 is smoothed through smoothing circuit 19 and thus changed into the DC current to be supplied to load 20. The minute fluctuation of the output voltage due to the change of the impedance of load 20 is fed back to part 17 via negative feedback circuit 20 to correct and stabilize the fluctuation of the output voltage. In such way, a low-cost, compact and light-weight constant voltage power unit, which can set the free voltage, can be obtained.

Abstract: PURPOSE:To enable appropriate paper feed and paper discharge to be performed through operating the same switch, by detecting whether paper is present or absent, feeding the paper to a printable position, deciding whether printing can be performed, and switching a function of external input. CONSTITUTION:With an execution switch 3 depressed, a signal from a paper sensor 2 is read to check whether paper is present or absent. When the level of the signal from the sensor 2 is LOW, it is judged that the paper is present. The record at the time of the preceding paper feeding is checked, and where a new paper is pushed in after discharge of the preceding paper, the paper is fed by about 200 steps by a paper-feeding motor 1, whereby the paper is fed to a printable position. Where paper discharge is not just finished, the paper is fed by a one-line amount. When the level of the signal from the sensor 2 is HIGH, it is judged that the paper is absent, and this condition is stored. The paper feed quantity after the paper is discharged is checked, and when printing can be performed, the paper is fed by a one-line amount. When printing can not be performed, the paper is fed by about 600 steps until the paper is completely discharged.

Title: Power source equipment
Inventor: SATO MITSUTAKE
IPC: H02J9/06
Filed: 1988-06-21
Abstract: PURPOSE:To improve power loss without sacrifice of the system reliability by connecting first and second power sources in parallel with a load through respective power FETs then detecting the voltage difference between the drain and the source of the FET and controlling the gate voltage such that the FET is turned OFF when it is biases reversely. CONSTITUTION:When the output voltage of a power source P2 increases with some reason, the base voltage of the transistor T2 in a detection control circuit C1 increases accordingly and functions to turn the transistor T2 ON and to turn a transistor T1 OFF. Consequently, voltage drop across a resistor R4 increases to lower the gate voltage of a FETQ 1 and to turn the FETQ 1 OFF thus continuing normal operation of a power source P1 with no influence of output voltage rise of the power source P2. Then the power source P2 is interrupted through an incorporated over voltage protection circuit and normal voltage is fed from the power source P1 to a load L.

Title: Method of oscillating laser beam in solid-state laser device
Inventor: KOJIMA MINORU
IPC: H01S3/092
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To largely reduce the energy density of a laser beam at the time of initial laser oscillation, by gradually increasing power to be supplied to excitation lamps of a solid-state laser device to a specified value. SOLUTION: When a solid-state laser medium 1 is excited, high power is not supplied drastically to excitation lamps 2 and 2, but power is supplied to them in such a manner that its level is increased step by step. By supplying the power in this manner, the energy density of a laser beam at the time of initial laser oscillation can be kept low. Therefore, such a laser beam whose energy density is high at the time of the initial laser oscillation will never damage the optical coatings of an output mirror 3, a total reflection mirror 4, and an external shutter mirror 10. At the same time, such a laser beam will never damage the laser beam incident end of an optical fiber, either. Moreover, high-quality laser processes can be performed using high-quality lser beams that exhibit less time-dependent output fluctuations.

Filed: 1985-07-10
Abstract: PURPOSE:To reduce the motion steps of a robot and to increase the operability by providing a distance detector on the periphery centering around the shaft of a welding torch and the driving mechanism to locate it with its rotation and by detecting the symmetrical position independently of the robot motion. CONSTITUTION:A welding torch 3 is located on a welding start point P5 because of the welding start point P5 and the same completion P6 being taught in advance. Now when a distance sensor 5 is rotated once by a driving device 6, the detection value for the scanning line 7 of the distance sensor 6 becomes points A13-A15. The points A16-A18 are found with one rotation of the distance sensor 5 once again by moving the welding torch 3 along the weld line to a position P7 then. The equation of space straight lines l1, l2, l3 is found by using the points A13-A18. Consequently the cross point of the space straight lines l1, l2 corresponds to a welding start point WS and the l3 becomes corresponding to the weld line direction and found by a formula and these operations are performed by using a control device 10.

Abstract: PURPOSE:To enable to check the normality of clock, by detecting whether the clock of the phases A and B is alternately output or not. CONSTITUTION:When a clock A1 of the phase A keeps ''1'' on the way, the output signal of an OR circuit 7 enters an AND gate 6. On the other hand, the clock of the phase B is input to an AND gate 2 and the output signal is output to the gate 6. The output of the gate 6 sets a latch circuit 11 via an OR gate 9. Further, the clock failure signal is output from the circuit 11. When either one clocks of the phase A is stopped, since no signal is output from the gate 1 and the latch 10 is not set, the phase B holds the set state. Next, an output signal is made from a gate 5 with the clock of the phase B (output signal of the gate 2) and failure signal is output via the circuit 11.

Abstract: PURPOSE: To achieve a comfortable hot air heating by providing a combustor of a hot air heater with a means of easily adjusting the quantity of hot air and the combustion level simply by changing the angle of an air direction plate of a hot air diffusion port.  
     CONSTITUTION: Air for hot air flows in through an air port 11 with a fan 2 driven with a motor 1 and diffused into the room through a diffuser 7 passing through a clearance between a outer cylinder 3 and an air rectifying plate 4. A combustion chamber 5 is turned to a negative pressure owing to an ejector effect produced when the air flow passes through the outer cylinder 3 and the air rectifying plate 4 and an air for combustion is fed into a burner 6 from the bottom thereof differential pressure from the atmospheric pressure. The air flow is mixed with a high temperature combustion exhaust gas and diffused through the diffuser 7 as hot air. The quantity of air for combustion herein used is roughly proportional to the passing speed of the air for hot air and the burner 6 burns kerosine proportional to the quantity as vaporized with a vaporizer section 8b. Therefore, the adjustment of the angle of the air rectifying plate 7' provides the combustion level proportional to the variation of the quantity of hot air.
