Title: Optical fiber gyro
Inventor: USUI TAKESHI
IPC: G01C19/64
Filed: 1982-07-15
Abstract: PURPOSE:To measure a rotating angular speed precisely by canceling variation in the wavelength of a lght source by variation in the attenuation of an optical attenuator. CONSTITUTION:A photodetector 6 detects the intensity of incident light and a control circuit 7 compares its detection signal with a set reference voltage to control the oscillation frequency of an oscillator 8 so that they are equal to each other. For this purpose, variation in phase difference by sagnace effect is canceled by variation in phase difference resulting from that an acousto-optic modulator 3 shifts the light signal in frequency, finding the revolving angular speed from frequency variation from the oscillation frequency in a stationary state. In this case, if the light emission wavelength of the light source varies, the light signal outputted to the side of the photodetector 6 varies in intensity. On the other hand, the optical attenuator 5 which varies in attenuation with wavelength is installed in front of the photodetector 6 to compensate variation in light intensity with the light emission wavelength by variation of the optical attenuator, so even if wavelength variation occurs, the rotating angular speed is detected precisely.

Title: Power supply, discharge lamp lighting apparatus and lighting apparatus
Inventor: KITAMURA NORIYUKI
IPC: H02M7/5387
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To surely start an inverter with a low price starting circuit. SOLUTION: When a power switch is turned on, a rectified current from a rectifying circuit 2 charges a capacitor C1 through a resistor R1, its terminal voltage is applied to the gate of a transistor Q1, when it exceeds a preset voltage, the transistor Q1 turns on. When the transistor Q1 turns on, the rectified current flows through the transistor Q1, the primary side CT1 of a saturable transformer, a linkage transformer 3 and a capacitor C4. In this case, charges of the capacitor C1 are discharged through the transistor Q1. When the voltage becomes lower than the preset voltage, the transistor Q1 turns off and an inverse current flows into the primary side CT1 of the saturable transformer to turn on a transistor Q2. Subsequently, the transistor Q1, Q2 are switched.  When these transistors Q1, Q2 are switched, a high frequency voltage is generated in the resistor R5 and this voltage causes a transistor Q3 to switch on for discharging the capacitor C1.

Title: Vertical type heat transfer tube
Inventor: KOKUBO YUUHEI
IPC: F28F17/00
Filed: 1980-09-09
Abstract: PURPOSE: To improve the efficiency of condensing action, by providing a vertical wall of a vertical type heat transfer tube with an inclined groove part and a grooveless part.  
     CONSTITUTION: The condensation heat transfer tube 1 is formed with the inclined groove part 2 for serving as main heat transfer means and the vertical grooveless part 3 for collecting the condensed liquid formed at the part 2 and for permitting it to flow down. Condensation occurs at the inclined groove part 2, and the condensed liquid produced flows down along inclined grooves 4. The condensed liquid collects to the grooveless part 3, and flows along the tube surface swiftly to be discharge. The angle of the inclined grooves is in the range from 50W85° for a condensate for example from Fron, petroleum or the like vapors to facilitate the efficiency for removal of the condensed liquid. Consequently, as the condensing action and the removal action for the condensate are balanced not to increase the thickness of the liquid film on the heat transfer surface beyond a certain level, the condensation heat transfer effect can be maintained high.

Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To surely draw a took which firmly sticks to a main spindle, by using a tool drawing mechanism, which is linked with a piston and is simple in construction. SOLUTION: A hammer base 11 is supported by a frame 10 of an auxiliary drawing device 2 in an ascendable/descendable manner, while the hammer 12 is energized downward by a spring 14. An engaging shaft 8 of the piston 6 is provided with a contact plate 16 and a working claw 20, while a slider 23 on a block 22 is press-contacted with the working claw 20 by means of a spring 24.

At the almost bottom end of the motion of the piston 6, the working claw 20 dissociates the locking claw 23a from the base 11, thereby releasing the energyzing force of the spring 14.  At the same time, the hammer 12 strikes the contact plate 16, so that the impact force is given to a tool via the piston 6 and a draw bar.
