Title: Exhaust-brake operation instructing apparatus for vehicle
Inventor: IKEDA TERUO
IPC: F02B77/08
Filed: 1983-01-31
Abstract: PURPOSE:To operate exhaust brake effectively, by providing an operational-condition detecting means in a vehicle equipped with exhaust brake, and operating a display section through detection of conditions for operating the exhaust brake and conditions for causing shift-down of a transmission. CONSTITUTION:A control unit 3 is furnished with output signals of a load sensor 1A and a switch sensor 1D in an operational-condition detecting section 1 provided in a vehicle equipped with exhaust brake. In case of no-load operation of an engine and in case that the exhaust brake is not in operation, an exhaust- brake switch operation indicating lamp is lighted by a switch judging means 3B. In case that the exhaust brake is in operation, on the other hand, the vehicle speed and the engine speed are calculated from the output signals of a vehicle- speed sensor 1B and an engine-speed sensor IC, and the gear position is calculated from the above two signals. Here, if it is judged that overspeed rotation of the engine is not caused by shift-down of a transmission, a shift-down instructing lamp 2B is lighted by a judging means 3F.

Filed: 1988-01-26
Abstract: PURPOSE:To make it possible to positively detect a start of engagement by providing a movement detecting means for detecting a preset amount of move ment of a holder previously operated to a clamping-start condition toward a tool to be clamped. CONSTITUTION:When a holder 5 is operated to a clamping-start condition, a sensor-rod 19 is moved and retracted against an energizing force produced by abutting it on a detecting piece 22, and held at that place by operating a lock-cylinder 23. After a motor 11 for rotating the holder is driven, the move ment of the detecting piece 22 caused by a preset amount of movement of the holder 5 is detected by a proximity sensor 21. In like manner, a start of engagement is detected by detecting the amount of movement of the holder 5 moved to a tool to be clamped - side with the engagement, and thus the start of engagement can be positively detected.

Title: Detection of end point of etching
Inventor: ITO SHINICHI
IPC: H01L21/302
Filed: 1986-01-27
Abstract: PURPOSE:To detect the proper end point of etching easily by forming a film onto a substrate, leaving a scribing region and stopping etching when the region is exposed. CONSTITUTION:A film 2 as a gate oxide film is shaped, leaving a scribing region 1a on a semiconductor substrate 1. A film to be etched 8 is formed on the whole surface. The surface of the film 8 is etched until the scribing region 1a is exposed. Accordingly, since no film is shaped in the scribing region, substrate itself is exposed when the film to be etched is etched and the scribing region is exposed, thus easily detecting the end point of etching by detecting the exposure of the substrate.

Title: Recorder
Inventor: FUKUDA MASAYA
IPC: H04N9/835
Filed: 1984-01-31
Abstract: PURPOSE:To prevent crosstalk noises from being generated with simple constitution by overlapping a sound signal with an electric potential to change at inaudible low frequency in a video tape recorder (VTR) and shifting modulated frequency by means of the overlapped potential by inaudible high frequency between adjacent tracks. CONSTITUTION:In the titled device a carrier of an FM sound signal AFM from an FM modulator 17 is shifted by an added voltage because a voltage is added in adder 61. Thus carriers of the FM sound signal AFM are different from each other by DELTAf between adjacent tracks. As a result, even if signals in adjacent tracks are cross-talked, their demodulated components are made of only frequency higher than the DELTAf. Assuming that the DELTAf is 15kHz, these noises can be removed by a low-pass filter at the time of reproduction and demodulation.

Filed: 1988-01-26
Abstract: PURPOSE:To decide whether or not foreign matter is generated in a semiconductor manufacturing process by providing an exciting light irradiating means for the foreign matter and switching and using it and a light beam for normal foreign matter inspection. CONSTITUTION:A detection system for a foreign matter position, shape, etc., and a top lighting type fluorescent microscope system are switched by a switching mechanism 19, which consists of a linear moving base moves the exciting light generation light source 11, an exciting film 13, and a dichroic mirror 15 forth and back horizontally in one body while mounting them; and exciting light obtained from the light source 11 is excluded from the path R of reflected light in the backward movement state and put in the path R shown in a figure in the forward movement state. Consequently, fluorescent light generated by the foreign matter is photodetected or observed at almost, for example, 550nm to decide whether or not the foreign matter is generated in the semiconductor manufacturing process.

Title: Frame synchronization detection system
Inventor: NAGUMO MIKIO
IPC: H04N1/36
Filed: 1991-01-17
Abstract: PURPOSE:To attain the use of lots of control channels by using part of bits of synchronization bit pattern for synchronization monitor as a synchronization bit alternate pattern after the establishment of synchronization and assigning and using excess bits as a control channel. CONSTITUTION:When its own station detects a synchronization bit pattern at a head of a frame sent from an opposite station, an opposite station alarm 2 is cleared and sent to the opposite station to notice synchronization establishment. Upon the receipt of it, the opposite station sends a frame comprising a synchronization bit alternate pattern 3 and a control channel 4 succeedingly. Thus, its own station implements synchronization monitor using the synchronization bit alternate pattern 3 and transmission of control information using the control channel 4. On the other hand, when an error is consecutive for a prescribed synchronization protection stage number or over, its own station discriminates it to be out of synchronism. Then the alarm 2 in the frame is set to inform occurrence of a fault and uses again the synchronization bit pattern to implement synchronization establishment.

Title: Magnetic head
Inventor: SHINKAI SHIGERU
IPC: G11B5/265
Filed: 1992-01-31
Abstract: PURPOSE:To obtain the magnetic head which can rapidly deal with the trend toward the higher coercive force, lower circumferential speed and narrower track of a recording medium by integrating a head for recording of a lamination type and a head for reproduction of an MR element. CONSTITUTION:The head for recording is made into the laminated structure alternately laminated with magnetic metallic films 3 having a high saturation magnetic flux density and insulating films 4, by which the head for recording is provided with the sufficient recording capacity even to the high-coercive force recording medium. The thickness itself of the laminated layers 5 is a track width and, therefore, the track width can be set by the film thickness control of the laminated layers 5 and the narrowing of the tracks is facilitated. On the other hand, the head for reproduction is the MR element 14, the reproduced output of which does not depend on the relative speed with the recording medium and, therefore, the rapid dealing with the trend toward the lower circumferential speed is possible. The two heads are integrated by the structure formed with the head for reproduction on the end face in the medium traveling direction of the head for recording and, therefore, the track alignment of the two head is easy.
