Title: Judging device of oil kind on feeding oil
Inventor: YASUDA HAJIME
IPC: G01N29/12
Filed: 1988-09-12
Abstract: PURPOSE:To realize an inexpensive and compact apparatus without any complicated mechanisms to stretch a sensor to the oil level, by using a sonic sensor and judging an oil kind by catching a sonic change of the sucked exhaust gas. CONSTITUTION:In a sensor unit 14, a sonic sensor (microphone) 24 is contained to output the collected exhaust gas sound as a sonic signal (d) converted to an electric signal, being installed at an exhaust gas outlet 25 of an injector. In a decision circuit 28, the sonic signal (d) is analyzed and a pattern is compared whether it is gasoline gas or light oil gas. If it is the same oil kind as that of the oil feed apparatus, an allowable signal (h) for feeding oil is transmitted to energize a pump motor 2 and to force to change over (open valve) an air change-over valve 22. But if it is regarded as a different oil kind from the oil feed apparatus, the allowable signal (h) for feeding oil is not transmitted, feed suspension continues subsequently.

Title: Temperature sweeping type semiconductor spectroscope
Inventor: MATSUI YASUSHI
IPC: G02F1/21
Filed: 1985-10-14
Abstract: PURPOSE:To adjust face accuracy and an optical axis by using a high reflection factor face using a semiconductor crystal cut surface as a base for a resonance mirror, using an optical waveguide having a light confining function as an optical path, and using the temperature dependency of the refractive index of a semiconductor to change the optical length. CONSTITUTION:A semiconductor material in a GaAs or InP group is used as a material constituting the optical waveguide. Light l1 made incident upon the optical waveguide layer 2 generates Fabry-Perot interference between reflection films 4 on both the ends of the optical waveguide layer 2. When the temperature of the smiconductor constituting the optical waveguide is changed, the refractive index is also changed, so that the optical length is also changed. Consequently, the resonance condition is changed and only the light l2 with a specific wavelength can be transmitted. Thus, a compact and highly efficient spectroscope requiring no optical axis adjustment can be obtained by continuously repeating said temperature change.

IPC: H04N7/169
Filed: 1993-08-20
Abstract: PURPOSE: To obtain a system by which a desirable visual effect is obtained by controlling an error due to a transmission fault for a residual picture. CONSTITUTION: In the system to encode a digital television signal and to decode it, a signal indicating residual picture information is converted into plural sub- band signals indicating vertical frequency and horizontal frequency (14) and quantized. The quantized sub-band signals are transmitted after they are scrambled (16) by performing line shaffling before data compression processing is performed to the sub-band signal to reduce influence of a transmission channel error. Decoding (40), re-shaffling of line (38), inverse quantization and sub-band synthesis (30, 34) are included on a receiver side. An inverse operation of an operation on a transmitter side is performed on the receiver side. Therefore, error is controlled by the residual picture.
