Filed: 1991-04-19
Abstract: PURPOSE:To make it possible to conduct a test of a signal processing function at a high speed and with high precision without being affected by noise, by a construction wherein a circuit which can generate a signal equivalent to the one of a displacement sensor is incorporated inside signal processing IC. CONSTITUTION:A type absolute-type displacement sensor (ABS sensor) 1 outputs a signal corresponding to displacement of a movable element in relation to a fixed element. A simulation signal generating circuit 30 and an analog circuit 40 for processing a signal to be an object of a test are integrated in the same IC. The simulation signal generating circuit 30 operates in the same way as the ABS sensor 1 and is called a dummy sensor. The analog circuit 40 comprises demodulation circuits 3 to 5 and phase detecting circuits 6 to 8. When it processes a sensor output as a signal processing circuit, various signals are inputted to the signal processing circuit from the dummy sensor 30 and it is determined whether or not a desired characteristic is obtained therefrom. When the dummy sensor 30 is used in this way, no mixing-in of noise occurs, measuring conditions can be altered quickly, in addition, and thus a performance test of a capacitance-type displacement measuring apparatus can be conducted at a high speed and with high precision.

Title: Multicylinder internal-combustion engine
Inventor: MURAMATSU TATSUHIRO
IPC: F02B27/02
Filed: 1983-06-30
Abstract: PURPOSE:To keep off a cylinder noise in neutral without entailing any drop in engine output in time of engine driving, by coupling each of suction air passages with a coupling passage, while closing the coupling passage in the neutral by means of a shift operating mechanism. CONSTITUTION:When a shift operating mechanism 32 is in a neutral N position, a neutral lamp 36 is lighted for indication. Therefore, at an electric circuit 34 being coupled with the neutral lamp 36, an electric current flows, turning a solenoid valve 30 to ON. Accordingly, a valve body 28 of a neutral valve 30 is promected outward, closing a coupling passage, whereby both first and second suction air passages 12 and 16 are intercepted, checking the propagation of a pressure wave acting on each cylinder, thus the generation of a cylinder noise is preventable from occurring. On the other hand, when the shift operating mechanism 32 is in a position other than the neutral or in time of engine driving, the neutral lamp 36 is no longer lighted and indicated and thereby the valve body 28 opens the coupling passage 24. With this constitution, the cylinder noise can be kept back from occurring owing to a dynamic effect of the coupling passage 24.

Title: Encoding method
Inventor: OKAMURA SHIROU
IPC: H04B14/04
Filed: 1980-08-26
Abstract: PURPOSE:To reduce the influence of dropout, etc., by converting a center level part of an analog signal to a code having the most same polarity bits, in case when the analog signal is converted to a digital signal. CONSTITUTION:An analog sicnal is converted to a digital signal by use of a code 3 or 4, which has many same polarity bits such as 1111, 0000 in a center level part of the analog signal, and also decreases the number of codes having the same polarity in principle toward the upper and lower end levels. According to such encoding, even if dropout occurs and the code is varied to 1111, 0000, only the regenerative signal level is varied to a center level, and comparing with the case of natural binary encoding, no maximum nor minimum level is shown, and its influence is reduced.
