摘要： PURPOSE:To make temperature drift small, to make sensitivity high and to decrease man-hours by providing driving electrodes for exciting bending oscillations on an oscillating body, and providing detecting electrodes for detecting piezoelectricity corresponding to strain generated in the oscillating body in response to the angular velocity around the longitudinal axis of the oscillating body. CONSTITUTION:These electrodes comprise driving electrodes 3a, 3b, 4a and 4b and detecting electrodes 5a and 5b. The electrodes 3a and 3b are formed on a face A and a face C, respectively, and interconnected on a sound piece 10 with thin films. The electrodes 4a and 4b are formed on a surface B and a surface D, respectively, and interconnected on the sound piece 10 with thin films. Meanwhile, the electrodes 5a and 5b are formed on a surface B and a surface D, respectively. Since supporting wires 1a, 1b, 2a and 2b are connected to the driving electrodes and the detecting electrodes having the different polarities, the supporting wires can be used for the role of lead wires for applying driving voltages and leading out the detected voltages. Therefore, when the patterns of the electrodes 3a and 3b are made to correspond to the patterns of the electrodes 4a and 4b, the effects of the electric fields of the electrodes 3a and 3b on the electrodes 5a and 5b can be alleviated.

摘要： PURPOSE:To lessen any damage on the contact of a hot-line insertion/extraction connector caused by spark discharge by driving a pin contact at a high speed by, making use of the restoring force of a spring, in the case of the contact opening speed of a power supply terminal. CONSTITUTION:The restoring force of a spring 13 is smaller than the insertion/ extraction force of catching a pin contact 15 that a socket contact 22 shows when the pin contact 15 is connected the socket contact to the contact 15, 22. Accordingly, the spring 13 is left contacted between the flange of the contact 15 and the flange of the cover 12 until the condition right before both contacts 15 and 22 separate from each other. At the instant when both a receptacle 2 and a header 1 separate from each other by driving them relatively right and left, the contact 15 is driven rightward quickly by the restoring force of the spring 13, and both are separated from each other quickly. Accordingly, the spark discharge time is smaller enough than that in the case of separation by man hand, so the spark discharge can be finished quickly.

摘要： PURPOSE:To concurrently confirm the type of a connector in a wide meaning at the time of confirming that two coupling sections of the connector are coupled by fitting a magnetized body with the preset magnetization pattern to two coupling sections coupled with each other of the connector. CONSTITUTION:A magnetized body 14 with the preset magnetization pattern is fitted to two coupling sections 11 and 12 coupled with each other of a connector. A plug is coupled with a receptacle while a movable section 11 is not coupled with a fixed section 12, the movable section 11 is coupled with the fixed section 12 to lock the coupling state of the plug and the receptacle, then magnetic detector 34 is arranged on the movable section 11 and the fixed section 12, and the magnetization pattern of the magnetized body 14 is read out at once. It is thereby confirmed that the movable section 11 is coupled with the fixed section 12, i.e., that the coupling state of the plug and the receptacle is locked, and also the type of the connector is confirmed.

摘要： PURPOSE:To make it unnecessary to cut off an electric power supply, and also to prevent an inductive fault, by constituting so that the operation is stopped by stopping a shift pulse against a shift register. CONSTITUTION:When a stop switch 26 is set to off, a clock pulse is generated from a clock pulse generator 13, and is supplied to clock terminals C-1-C-5 of each FF. An auxiliary switch 20 is also operated by interlocking with the switch 26, and supply voltage is applied to the input terminal connected to a capacitor 18 of an NAND circuit 16, a shift register 12 starts its shufting operation, and a pseudo random pulse is generated from an output terminal Q-5 of the FF11-5 of the final stage. When stopping the operation of the register 12, the switch 26 is turned on. As a result, supply of the clock pulse from the generator 13 is stopped, and the operation of the register 12 is stopped. Accordingly, the operation can be stopped easily without cutting off a common electric power supply with a system apparatus.

摘要： PURPOSE:To effectively hold a centered state and to fix an optical fiber in a package by centering a laser diode and the optical fiber and then using a microscope used for said centering. CONSTITUTION:The system is provided with the microscope 21 for observing the optical fiber 11 and the laser diode package 15 and a laser source for supplying laser energy for fixing the fiber 11 on the package 15. Centering is executed so that light from the laser diode 14 in the package 15 can be efficiently made incident on the fiber 11 and laser energy is focused on a fixed position on the screen of the microscope. The fixed position is moved to a fixed point of the fiber 11 in the package 15 and then laser energy is radiated to fix the fiber 11 on the package 15. Consequently, accurate positioning can be attained and the optical fiber 11 can be prevented from being shifted due to thermal distortion generated at the time of fixing.

摘要： PURPOSE:To simplify configuration of an electric circuit by frequency sweeping frequency of reference laser light for making optical heterodyne detection using a optical frequency modulator. CONSTITUTION:Laser light 2 emitted from a laser light source 1 is branched into two 2A, 2B by a light branching device 3. One of branched 3 laser light 2A is supplied to an optical path that constitutes an object to be measured. Another laser light 2B is fed to a optical frequency modulator 5. Assuming that frequency of laser light is fL, frequency deviation received by the object to be measured 4B is fX, and frequency to be modulated is fB, optical frequency passed through the object 4B becomes fL+fX, and frequency of modulated 5 signal goes to fL+fB. Accordingly, the output voltage of counted value of a counter 7B and a converter 7C can be taken in circuits 13, 14 by detecting signals when the signals are outputted from a band pass filter 11, then applied with waveform shaping and supplying them to a latch circuit 13 and an analog holding circuit 14. Further, it is possible to find frequency deviation fX received by the object 4B by finding the counted value or voltage value.
