Patent JP-H09307160-A (JP)
Title: Laser equipment
Inventor: ANDO TETSUO
IPC: H01S3/16
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To reduce SHG noise and stabilize output, by installing two or more wavelength band selecting means in a resonator, in a solid laser of semiconductor laser pumping. SOLUTION: An inner resonator type SHG laser equipment is constituted by using a solid laser crystal 4, a non-linear type optical crystal 5, coating 20 on the left surface of the solid laser crystal 4 and coating 22 on the left curved surface of an output mirror 7. An etalon 6 is arranged in a resonator. Wavelength selectivity of the etalon 6 shifts wavelength of transmittance peak by changing the angle to the travelling direction of laser. Since the wavelength selecting width of the etalon 6 is narrow, the fundamental wave 11 turns to a longitudinal single mode. When phase matching wavelength is made to coincide with the fundamental wave, length an SHG light 12 is obtained. Therefore, the inner resonator type SHG laser can be operated with stable output free from noise.

Title: Driving method of inverter employing transistor for switching element
Inventor: KANAYAMA EIZOU
IPC: H02M7/538
Filed: 1979-09-14
Abstract: PURPOSE:To enable easy oscillation of transistors with a pulse by conducting thyristors with a cyclical trigger pulse given alternately so that the transistors switched ON is fully turned OFF while those switched OFF are turned ON. CONSTITUTION:A power source for reducing the time for accumulating charges of transistors Q1 and Q2 and a power source E2 adapted to concurrently serve as a power supply for commutation of SCR1 and SCR2 to switch the transistors Q1 and Q2 OFF are provided. For example, it is assumed that the transistor Q1 is ON while a transistor Q2 is OFF. When a trigger pulse is given to conduct the gate of SCR1, the transistor Q1 is fully switched OFF causing the transistor Q2 to turn ON. Upon the turning ON of the transistor Q1 turned, the SCR1 triggered is led to commutation. This can cause excitation with a pulse as easily as it could by heretofore done in triggering of the gate of the thyristor by use of a bipolar transistor or the like for switching element thereby eliminating short-circuit otherwise caused by accumulating charge.

Filed: 1977-09-30
Abstract: PURPOSE: To supply engine with mixture gas of an air-fuel ratio suited for warming- up of engine, without handling choke lever, by automatically decreasing the number of starting fuel supplying passages after starting of engine.  
     CONSTITUTION: Starting suction passages 8, 8' are formed in parallel with main passage 3 and these passages 8, 8' are communicated or closed by disk valve 7 which is turned in normal or reverse direction by choke lever 6. Starting fuel supplying passages 9, 10 are communicated to the suction passages 8, 8' only when the passages 8, 8' are communicated with each other. When the passages 8, 8' are communicated, fiel is drawn into the passages 8, 8' and a rich mixture is supplied to intake pipe 2. The passage 10 is connected with a negative-pressure valve 13 for closing the fuel supplying passage 10 after starting of engine, which is opened or closed depending on the level of suction vacuum in the main passage 3 to stop fuel supply from supply pipe 10, so that mixture suited for warming-up of engine can be obtained. When choke lever 6 is returned to its original position after the engine is warmed up completely, supply pipe 9 is also closed

Title: Variable-speed power generation system
Inventor: TSUJI EIJI
IPC: H02P9/00
Filed: 1991-05-22
Abstract: PURPOSE:To prevent the overheated damage on a neutral resistance by a harmonic current generated from a frequency converter. CONSTITUTION:A harmonic current flowing through the neutral resistance 2 of a variable-speed power generation system flows via a closed circuit composed of a frequency converter 6, generator-motor 1, neutral grounding circuit and the electrostatic capacitance to ground of the power supply cable 8 of an excited power supply. Because the electrostatic capacitance to ground of the power supply cable is limited so that electric current flowing through this neutral resistor 2 is its rated withstand current value and below, it is possible to prevent the heating damage to the neutral resistor 2.

Title: Document scanning technology using spiral path locus
Inventor: CARIFFE ALLEN E
IPC: G02B26/10
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To entirely preclude the artifact by giving a relative motion in between a sensor array and a medium so that the sensor array demarcates a spiral locus with respect to the medium in an optical scanning cycle. SOLUTION: During a scanning cycle, the optical sensor array for collecting image pixel data from a flat medium 10 is used. A carriage driving device 72 and a turntable drive 92 give a relative motion in between the optical sensor array and the medium 10 and, as a result, a spiral locus is demarcated by the sensor array facing to the medium during the scanning cycle. The maximum diameter of this spiral equals to the dimension of the diagonal line of the rectangular medium. Consequently, even when the sensor array is brought to be in very close proximity to edges of the medium, it can collect the pixel data. Thus, marginal areas of both sides and the upper and lower edges of the medium where the sanning can not be performed are made to be reduced or precluded.
