Title: Object detector
Inventor: KUBO MASATOSHI
IPC: G01V3/08
Filed: 1993-02-25
Abstract: PURPOSE:To eliminate the need of frequency detecting circuit by providing an electrode disposed oppositely to a space to be detected, an additional unit constituting an oscillation circuit along with the electrode, and a Q detector for detecting fluctuation of quality factor of the oscillation circuit. CONSTITUTION:An electrode 11 is connected with an additional unit 20 constituting an oscillation circuit S along with the electrode 10. The additional unit 20 comprises an amplifier circuit 21 and a positive feedback element 22 connected in parallel with the electrode 10. The circuit 21 is connected, on the output side thereof, with a Q detector 30 for detecting fluctuation of quality factor Q of the circuit S. When power is fed to the unit 20, an electric field is established in a space around the electrode 10. When an object intrudes into the space, the quality factor Q of the circuit S fluctuates. The Q detector 30 detects the fluctuation of quality factor Q thus detecting intrusion of the object.

Title: Prepoduction of beta-alumina diaphragm for electrolysis
Inventor: YOSHIDA HIROYUKI
IPC: C04B35/113
Filed: 1978-05-26
Abstract: PURPOSE: To lengthen life by reproducing diaphragm by heat-treating beta-alumina when voltage to be applied to electrolyte is risen to a definite range beyond the initial voltage in the electrolysis of molten Na(salt) using beta-alumina diaphragm.  
     CONSTITUTION: When electrolytic voltage rises to an extent not 2 V more than the initial voltage, beta-alumina diaphragm is removed, and then the beta-alumina diaphragm removed is heat-treated at a temperature more than 750°C and 50°C lower than the sintering temperature of the beta-alumina diaphragm. The use of the diaphragm reproduced in this way in electrolysis results in the coincidence of electrolytic voltage with the initial electrolytic voltage, thus preventing the destruction of diaphragm. The reproduction of the diaphragm is made each time electrolytic voltage rises.

Title: Semiconductor optical bistable element
Inventor: TOKUDA YASUKI
IPC: G02F1/35
Filed: 1988-03-16
Abstract: PURPOSE:To obtain the semiconductor optical bistable element which can be controlled by control light by forming a part of a p- or n-type semiconductor layer in an intrinsic region having high resistance and absorbing only the control light in this region to form photocarriers, thereby changing the resistance. CONSTITUTION:The semiconductor bistable element having a pin structure is made into the structure in which a part of the p or n region of said element is made into the intrinsic region having >=5,000Angstrom  thickness or sufficiently large band gap and the high resistance. The element resistance is, therefore, fairly high when there is no control light. The control light is absorbed by the intrinsic layer 12 and the photocarriers are formed when the control light is projected on such element structure. The resistance over the entire part of the element is thereby lowered and the element resistance value is controlled by the control light. Since the input light is long in wavelength, said light is not absorbed by the intrinsic layer 12.

Abstract: PURPOSE:To improve the stability by using a D/A converter converting a digital frequency setting signal into a DC frequency-setting signal and a V/F converter outputting a frequency signal by the DC frequency-setting signal so as to constitute the oscillating means. CONSTITUTION:The oscillator 10 outputting a basic clock signal consists of the D/A converter 11 and the V/F converter 12 and in inputting a digital frequency setting signal (i) to the D/A converter 11, a DC voltage (m) is outputted depending on the value.

Thus, an output waveform with a high frequency is obtained from a low frequency setting signal by varying the frequency of the basic clock signal. Thus, no tight design in the operating timing of each section is not required, the circuit design is facilitated and the adverse effect of the environment of the components is less. Thus, the reliability and stability are both improved.
