Title: Fixed optical attenuator
Inventor: TSUCHINUMA KENICHI
IPC: G02B6/26
Filed: 1979-10-26
Abstract: PURPOSE:To obtain a fixed attenuator free from the return of reflected light by providing optical attenuating characteristics controlled to predetermined values to a focusing rod lens made of silicic acid glass contg. metal ion. CONSTITUTION:Focusing rod lens 10 is obtd. by mixing 0.01-0.1wt% Cu<2+>, Cr<3+>, Fe<2+> or other metal ion into silicic acid glass consisting essentially of SiO2, B2O3, Na2O and Tl2O3. A pair of optical fibers 11, 12 are coupled to the light beam incident and emergent parts of lens 10, respectively while allowing their optical axes to agree with each other. The metal ion mixed into the silicic acid glass as impurity causes light absorption due to material absorption in lens 10, resulting in high quality lens 10 with very high purity and no optical attenuating characteristics. Thus, an attenuator free from the return of reflected light can be obtd.

Abstract: PURPOSE: To prevent malfunction of an IGBT drive circuit due to noise by keeping the turn-on characteristics of an IGBT in harmony with diode recovery characteristics and suppressing overshoot voltage and a voltage vibration even at a high-speed operation of the IGBT. CONSTITUTION: An IGBT 29 and a diode 30 are connected in inverse parallel on a collector electrode plate 23. Also, the emitter of the IGBT 29 is connected to an emitter electrode plate 24, the gate is connected to a gate electrode plate 25, and the anode of the diode 30 is connected to the emitter electrode plate 24 by a wire. A capacitor 31 is connected between the collector electrode plate 23 and the emitter electrode plate 24. Then, by increasing the parasitic capacitance of the IGBT and diode or connecting a capacitor instead, the peak value of a voltage vibration can be reduced. The peak value of the overshoot voltage is suppressed to 1/3 or less of a rated voltage.

Title: Rotary compressor
Inventor: SEKIMOTO SHINYA
IPC: F04B39/00
Filed: 1983-07-29
Abstract: PURPOSE:To suppress noise by allowing the outside surface of casing of a compressor body to attract two semi-cylindrical permanent magnets to function as a damper, and thereby suppressing possible torsional vibration. CONSTITUTION:Outside surface of the casing 20 of a compressor body shall attract two semi-cylindrical permanent magnets 22, 23 to function as a damper. That is, the bond between these magnets 22, 23 and the casing 20 is only due to magnetic force. Accordingly, even when the casing 20 begins torsional vibration, the magnets 22, 23 are willing to retain their original positions owing to the inertia force deriving from their own gravities, without making followup motion to said torsional vibration, but sliding on the outside surface of the casing 20. Thereby a frictional force is generated at the attraction parts between casing 20 and magnets 22, 23 because of said sliding to bring about the torsional vibration. Thus noise likely otherwise generated by such torsional vibration can be suppressed.
