Title: Output control apparatus for laser
Inventor: WAKABAYASHI OSAMU
IPC: H01S3/131
Filed: 1990-08-30
Abstract: PURPOSE:To control an output with high accuracy without actually measuring the ratio of a P-polarization to an S-polarization by a method wherein partial reflection characteristics and incidence angles of a first partial reflecting mirror and a second partial reflecting mirror are set respectively to be identical. CONSTITUTION:A laser beam generated by a laser medium 1 is output from an output coupling mirror 2; one part of the laser beam is reflected by a first partial reflecting mirror 6, and is then incident on a second partial reflecting mirror 7. Partial reflection characteristics of both partial reflecting mirrors are set to be identical and their incidence angles are set respectively to be identical. Consequently, when reflection factors of S-polarizations of the mirrors 6 and 7 are designated respectively as Rs and Rs' and reflection factors of their P-polarizations are designated as Rp and Rp', Rs=Rs' and Rp=Rp' are materialized. Since the incident and reflecting face of the mirror 7 is installed so as to be perpendicular to that of the mirror 6, P-polarized waves generated by the medium 1 are incident on an optical-intensity detector 4 at a ratio of (RpXRs') and S-polarized waves are incident on it at a ratio of (RsXRp'). Since Rs=Rs' and Rp=Rp' are set up, both waves are set to the same value and are incident on the optical-intensity detector 4.

Filed: 1987-09-16
Abstract: PURPOSE:To reduce leak current by making the concentration of impurities of source and drain areas of MISFET constituting memory cell to be different from that of source and drain areas of MISFET constituting peripheral circuit. CONSTITUTION:In a dynamic RAM, the concentration of impulities of a source area 8 and a drain area 9 of n-channel MISFET Q2 constituting memory cell is formed to be lower than that of a source area 6 and a drain area 7 of n- channel MISFET Q1 constituting peripheral circuit.

Filed: 1992-08-28
Abstract: PURPOSE:To provide a small and light operating device in a simple constitution, which presents good easiness in handling without sense of restraint, enables simultaneous operation of switches, and allows effective execution of works. CONSTITUTION:A drive part 3 equipped with an actuator 3a such as motor is installed inside of a grip 2 which the operator 4 holds.

Abstract: PROBLEM TO BE SOLVED: To improve damping characteristics with small energy by arranging an actuator for applying force to a support element in a direction along reaction, and a control system for causing motion of the actuator suitable for minimizing displacement of a mass element of a main system. SOLUTION: A support element S has a mass Mo, and receives reaction from a spring element 22, and a damping element 23 in respect to a mass element 21. An active damping device A is serially arranged to a passive damping device p through the support element S. The active damping device has an actuator 24 arranged between the support element S and the mass element 11 for applying force to the support element S in the direction along the repulsion, and a control system 25 for causing the motion of the actuator 34 suitably for minimizing displacement of the mass element 11.

Filed: 1986-09-29
Abstract: PURPOSE:To ensure the control of Q of a tuning circuit by connecting a series connected matter of a 2nd controllable coil and a resistor in parallel to a 1st controllable coil to form a tuning inductance. CONSTITUTION:A turning inductance of a tuning circuit is formed by connecting a series connected matter of the 2nd controllable coil 11 and a resistor 12 in parallel to the 1st controllable coil 10. Then the inductance of the coil 10 is roughly controlled; while the inductance of the coil 11 is finely controlled. As a result, the damping effect produced by the resistance 12 is reduced and Q of the tuning circuit is increased. If said control of inductance is reversed between both coils 10 and 11, the damping effect of the resistor 12 is increased with the Q reduced respectively. Thus the Q of the tuning circuit can be controlled.

Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To convert a signal of the noninterlace system into a signal of the interlace system in real time without causing flicker with a simple configuration without increasing the cost. SOLUTION: An analog video signal outputted from an image processing unit is delayed by one line at an analog delay circuit 2 and the delayed video signal is multiplied with an analog video signal of a succeeding line with a coefficient at an analog adder 3 to generate a field video signal. Then the speed of the field video signal is halved by a double speed/equal speed converter 4. Based on the field video signal, a video encoder generates a video signal. When an analog video signal by one frame is outputted from the image processing unit, a video signal of an odd numbered frame is generated as above and a video signal of an even numbered frame is generated based on an analog video signal of a succeeding frame.

Abstract: PURPOSE:To prevent data in a non-volatile memory from the generating an error by forming a traveling distance calculating means, the non-volatile memory, a traveling distance data updating means, a power supply circuit, a switching means, a power supply limiting means, etc. CONSTITUTION:A pulse signal from a car speed sensor 1 is counted up by the traveling distance calculating means 2. Traveling distance data are stored in the non-volatile memory 3 and applied to the means 2. Every time when the counted distance reaches a prescribed distance, the updating means 4 updates the traveling distance data stored in the memory 3. Even if an ignition switch 5 is opened, electric power is selectively supplied by a power supply circuit 6 without being passed through the switch 5. If the opening of the switch 5 is detected at the updating of the data, the switching means 8 is driven by a power supply control means 7 during the updating of the data to supply power from the battery 9 mounted on a car to a power supply circuit 6. Even if the switch 5 is opened, the data in the memory 3 can be updated and no error is generated in the data of the memory 3.
