IPC: C04B41/80
Filed: 1989-12-05
Abstract: PURPOSE:To form the optical waveguide having excellent thermal stability by implanting >=2 kinds of ions constituting any of an oxide, nitride and halide onto a substrate from the surface thereof. CONSTITUTION:A Cr film 2 to serve as a mask at the time of ion implantation is formed on the surface of the substrate 1 consisting of quartz glass and an aperture 3 of an optical waveguide pattern is formed in the film 2 by a photolithographic technique. The ions 4 of >=2 kinds constituting any of the oxide, nitride or halide are then implanted onto the substrate 1 from the surface thereof and a heat treatment is applied thereto at need. The material of the substrate 1 forming the optical waveguide 5 may be any of glass, ceramics, semiconductor and metal. The elements of >=2 kinds implanted to the substrate 1 form a compd. by bonding to each other, thereby acting to provide the thermal stability. The optical waveguide having the excellent thermal stability is formed on the substrate having the high heat resistance in this way.

Title: Test circuit
Inventor: IWASE NOBUKAZU
IPC: G01R31/28
Filed: 1989-12-04
Abstract: PURPOSE:To set a programmable memory mode at high speed when a power supply is closed by providing a level detection part detecting a voltage level applied at every function block and a test signal output part. CONSTITUTION:At the time of the setting of a programmable memory (PROM) mode, function blocks 11 - 13 make the reset signal in an integrated circuit chip active so as not to exert effect on the access of a PROM 14 to set an operation stop state. Since the blocks 11 - 13 are in a function stop state, high voltage power supply terminals V1 - V3 may be the same potential as usual operation voltage power supply terminals G1 - G3 and potential is set when a power supply is closed in matching relation to various modes of the PROM. A level detection part 15 detects the voltage levels of the terminals V1 - V3 to form detection signals 1a - 1c and outputs the same to a test signal output part 16. The output part 16 receives the signals 1a - 1c to decode the same and forms a test signal 1d to output the same to the PROM 14 and an external function block 17.

Abstract: PURPOSE:To remove the effect of magnetization even if the body of a car to which a geomagnetism sensor is attached is magnetized and to detect an azimuth accurately all the time by arranging a magnetism correcting plate comprising a magnetic material at the outer surface of the geomagnetism sensor with a slight interval being provided between the geomagnetism sensor and the correcting plate. CONSTITUTION:Geomagnetism is decomposed into two orthogonally intersecting components within a horizontal plane, and the components are detected in a geomagnetism sensor 4. A geomagnetism correcting plate 9 comprizing a magnetic material is arranged in the horizontal direction around the outer surface of a case 7 containing the geomagnetism sensor 4. The right end of the roof 5 of a car is magnetized as an N pole and the left end is magnetized as an S pole when the car passed through a railroad crossing. At this time, the magnetism correcting plate 9 is also magnetized. The left edge side of a sensor inserting hole 8 which faces the geomagnetism sensor 4 is magnetized as an N pole, and the right edge side is magnetized as an S pole. Magnetic flux phi1 formed by the magnetization of the roof 5 whose magnetism flows through the ring-shaped core in the geomagnetsm sensor 4 and magnetic flux phi2 formed by the magnetization of the magnetism correcting plate 9 act in the directions so as to offset the magnetic fluxes to each other. Then screws 10 are turned, and the positions of the geomagnetism sensor 4 and the geomagnetism correcting plate 9 are adjusted. Thus the effect of the magnetization of the roof 5 can be eliminated.

Title: Device for reducing noise in car room
Inventor: KOYAMA YUICHI
IPC: B60R16/02
Filed: 1989-12-06
Abstract: PURPOSE:To remove not only a confined noise but also other noise components together by making an applicable step size variable in accordance with an output condition of a car audio equipment and controlling a speaker so as to minimize an input of a microphone, by means of a controller. CONSTITUTION:Engine vibration X(n) is converted into a car room noise Y(n) closely to ears and observed through a car room space transmission path by a transmission function G. Here the engine vibration itself is caused by an engine speed secondary component, but the noise Y(n) contains a component except the above described engine speed secondary component by the transmission function G. An engine vibration signal X(n) and an output signal e(n) from a microphone are always input. In a controller 5, and a filter coefficient train H is adequately controlled base on these signals by an LMS method or the like to generate a speaker output y(n) so as to cancel the car room noise Y(n). In this case a car audio output condition is fed to the controller 5, and the corresponding step size mu is selected to perform an applicable control.

Title: Driving device for stepping motor
Inventor: MATSUSHITA TAKESHI
IPC: H02P8/22
Filed: 1990-11-21
Abstract: PURPOSE:To make the generating torque of a stepping motor constant by providing a means for detecting the pattern of the numbers of turns of simultaneously excited windings and a reference value switching means which switches a reference value for changing the current flowing to the windings in corresponding to each pattern. CONSTITUTION:A reference value switching means 20ac (20bd) switches the value of a reference value S1 by changing the voltage dividing ratio between resistances Rs and R2 (R5) by connecting and separating the resistance Rs. Accordingly, when phase switching signals A and B are outputted, a set value switching signal E is outputted from a NOR gate 12. Then a transistor Tr is turned off and the resistance Rs is connected in series with resistances R3 and R2. Therefore, the reference value S1 becomes smaller and currents flowing through windings Ca and Cb are controlled to low values. On the other hand, when only the phase switching signal B is outputted, the transistor Tr is turned on and the reference value S1 and, accordingly, the current Ib becomes larger, since the set value switching signal E becomes a low level.
