Patent JP-H01314309-A (JP)
Title: Magnetic guidance system
Inventor: OKAMOTO AKIFUMI
IPC: G05D1/02
Filed: 1988-06-15
Abstract: PURPOSE:To prevent a moving body from deviating from a travel permitted course by installing magnetic markers at the external edge of the travel permitted area of the moving body and allowing the moving body to travel within the set range of the magnetic markers. CONSTITUTION:The magnetic markers 1 and 2 are laid along the external edge of the course of the moving body 3 previously and the moving body 3 is allowed to travel between the magnetic markers 1 and 2. If the moving body 3 deviates from its travel direction and a magnetic detecting element 4 or 5 is on the magnetic marker 1 or 2, the magnetic detecting element 4 or 5 detects the magnetic markers 1 or 2 and generates an output signal V1 or V2. As the generation time difference (t) between the output signals V2 and V1 is shorter and shorter, the degree of deviation from the traveling direction is larger and larger, so this time difference is selected properly to correct the traveling direction of the moving body 3. Consequently, the deviation is prevented completely.

Title: Composition for insulating paste
Inventor: FUKAI MOTOHARU
IPC: H01G4/12
Filed: 1989-06-08
Abstract: PURPOSE:To enable formation of a ceramic substrate having a high dielectric area by specifying the composition ratio of a composition for an insulating paste made up of the mixture or compound of Al2O3 and CuO. CONSTITUTION:The composition ratio of an insulating paste made up substantially of the mixture or compound of Al2O3 and CuO is so set that Al2O3 is 80.0 through 95.0mol% and that CuO is 5.0 through 20.0mol%. This composition for the insulating paste is applied on a ceramic molded body before primary baking. Then the insulating paste is diffused into a substrate before a grain growth of a material occurs, the grain growth in the part whereon the composition is applied is suppressed and thus the expansion of a low-dielectric part after baking is suppressed. Thereby the area of a high-dielectric part is maintained and the ceramic molded body can be used effectively.

Title: Managing method for cache page and medium stored with managing program for cache page
Inventor: UCHIDA MITSUJIRO
IPC: G06F12/12
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To detect a conflict between entries in a protection area and to automatically adjust the size of the protection area to a proper value by comparing the latest access times of both entries at the LRU positions in the protection area and an examination area with each other in case of a cache miss. SOLUTION: The time when each entry 3 is accessed most recently is stored and held. In case of a cache miss, the access times of both the LRU entries 3 held in the protection area 1 and examination area 2 are compared with each other. When the former is older, the LRU entry 3 in the protection area 1 is moved to an MRU position in the examination area 2 to reduce the size of the protection area 1, the entry 3 having caused the cache miss is added at the MRU position in the examination area 3, and the LRU entry 3 in the examination area 2 is expelled. When the latter is older, the LRU entry 3 in the examination area 2 is expelled and the entry 3 having caused the cache miss is added at the MRU position in the examination area 2 instead.

Title: Gain adjustment circuit for hand-free communication equipment
Inventor: NASU YOSHINORI
IPC: H04M1/60
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To obtain the gain adjustment circuit for a hand-free communication equipment without a sense of changeover between a transmission and a reception with high simultaneous speech performance by providing a loss provision means to provide a loss in response to the level of a reception signal to a transmission signal. SOLUTION: When a voice is inputted to a microphone 1, a transmission signal SS corresponding to the voice is outputted to a transmission loss circuit 6 and a changeover control circuit 5. Simultaneously when a reception signal SR is outputted from a radio reception section, the reception signal SR is simultaneously inputted to a reception signal loss circuit 3, a changeover control circuit 5 and a rectifier circuit 7. The changeover control circuit 5 converts an inputted transmission signal SS and the reception signal SR into a transmission voltage and a reception voltage and compares the both. When the reception signal SR is smaller than a prescribed level, a small loss is given to the transmission signal SS accordingly and when the reception signal SR is a prescribed level or over, a large loss is given to the transmission signal SS accordingly.

Title: Electronic controlled ignition advancing device of internal-combustion engine
Inventor: GOUHARA YOSHIHIRO
IPC: F02P5/04
Filed: 1982-08-25
Abstract: PURPOSE:To ignite at the optimum ignition timing by a method wherein the optimum ignition timing is obtained by an ignition timing setting device in accordance with the speed and the amount of suction air of the engine. CONSTITUTION:The engine speed is detected by a pulser coil 32. The opening degree of a throttle valve or the amount of suction air is detected by a throttle opening degree detector 46. The ignition timing setting device 51 reads out the optimum ignition timing in accordance with the speed and the amount of suction air of the engine from a map. An abnormal combustion detector 49 delays the ignition timing by sending a signal to the ignition timing setting device 51 when the knocking of the engine is detected. Obtained optimum ignition timing is compared with a crank angle, obtained by the pulser coil 32, a crank rotating angle signal generator 36 and a crank angle detector 52, and an ignition signal is outputted when they are coinciding with each other. According to this method, the optimum ignition timing without generating knocking may be obtained for the ignition of the engine.
