Title: Angular velocity detector
Inventor: OKABE TAKAHIRO
IPC: G01C19/00
Filed: 1982-11-23
Abstract: PURPOSE:To obtain an electrical signal output of the low frequency corresponding to an angular velocity by transmitting microwaves separately in right and left directions in the transmission path of a closed loop, oscillating the same in the transmission path, detecting the mixed wave and passing the detected output through a low-frequency amplifier means. CONSTITUTION:The microwave oscillated in a microwave oscillator 1 is equally divided by a magic T3 and rotates in the directions opposite to each other in a microwave transmission path. The clockwise and counterclockwise microwaves enter a mixed wave detector 4 via the magic T3 after making a round turn in the path 2 and are thus detected mixedly. When the microwave part rotates with respect to the absolute space, a difference arises in the oscillation frequencies f1, f2 of the clockwise and counterclockwise microwaves, and when such waves are mixedly detected with the detector 4, the low frequency DELTAf which is a frequency difference is generated. The frequency DELTAf is proportional directly to the angular speed omega in the microwave part. The low frequency passes a capacitor 5, is amplified in a low-frequency amplifier 6 and is displayed on a frequency display device 7.

Resin 15 is cast into the recessed parts 13 of the molding tool 14. The board 11 is superposed on the molding tool 14 so that the resin 15, which is cast into the recessed parts 13 of the molding tool, may penetrate the semiconductor chips 21 directed downward. The resin 15 is arranged to penetrate the semiconductor chips where pressure is applied to the resin, which spreads all over the corners, thereby inhibiting the generation of void in the resin. After the resin is cured under the condition which allows the board 11 to be superposed on the molding tool, the board 11 is separated from the molding tool 14. The cured resin serves to seal the semiconductor chips 12 mounted on the board 11.

Abstract: PROBLEM TO BE SOLVED: To provide a vibration alleviating apparatus for an air conditioner for reducing vibrations, by a repetition of a regenerative state and a power state of an induction motor of the conditioner to be driven by an inverter. SOLUTION: In an inverter 3, the variation in energy communicated between a DC power source 7 and a power converter 8 is detected as a voltage change by a voltage change detector 9. Only the change content of the voltage change is extracted from an AC component by a change content detector 10 is waveform shaped into a pulse. The pulse is outputted. A waveform calculator 11 calculates a regenerative frequency change amount and a power frequency change amount based on pulse widths of the pulses, corresponding to the regenerative state and the power state.  Thus, a fundamental frequency command value for designating the frequency of the converter 8 and a boosted chopper reference voltage command value for designating an output voltage of a booster chopper 6 are corrected, based on the regenerative frequency change value when regenerating or based on the power frequency change amount at the time of the power state, thereby controlling the direction for suppressing vibration.

IPC: G02B6/28
Filed: 1994-08-31
Abstract: PURPOSE: To provide a process for producing optical fiber couplers capable of simultaneously producing plural pieces of the optical fiber couplers having uniform characteristics. CONSTITUTION: The diameters of optical fibers 11, 12, 13, 14 and the diameters of optical fibers 22, 23 existing in the central part on an upper side are the same.

Four sets of the optical fibers combined above and below in such a manner are fused and stretched under heating. While the optical fibers in the central part are the same above and below, the upper and lower optical fibers on both sides have a difference in the clad diameters, by which the characteristics of the resulted four optical fiber couplers are made uniform in spite of the heating of the optical fibers on both sides strong with respect to the central part.
