Title: Apparatus for judging origin position of rotary body
Inventor: WADA KIYOSHI
IPC: G01D5/244
Filed: 1988-03-31
Abstract: PURPOSE:To accurately and rapidly judge a steering neutral position by a simple circuit constitution, by judging a sub-zone, wherein the integration time contributing to the detection of an origin range reaches a predetermined time at first in an origin zone, as an origin position. CONSTITUTION:A steering angle sensor 100 is constituted of a rotary disc 1 and photointerruptors 2-4 and slits 1a are opened on the disc 1 at a predetermined angular pitch P. An origin zone 1b is opened to the disc 1 and the rotary position where the slit 1b is opposed to the photointerruptor 4 is set as the origin position of the disc 1. The angle width alpha of the slit 1b is set to the three-angular pitch P of the slits 1a and the origin zone is divided into a plurality of sub-zones on the basis of the steering angle position detected by the sensor 100. Subsequently, the times contributing to the detection of the respective origin ranges of the divided sub-zones are integrated and the sub-zone wherein said integration time reaches a predetermined time at first is judged as the origin position. By this method, the origin position, that is, a steering neutral position can be accurately and rapidly judged by a simple circuit constitution.

Abstract: PURPOSE:To take out a signal having high frequency, by making a pitch of a coil piece of a comb-tooth-shaped coil into 1/N times (N is an integer other than 1) pitch of a magnetic pole of a rotary magnet in a speed detector used a whole circumference integral type frequency dynamo. CONSTITUTION:Printed circuit of a comb-tooth-shaped coil K is formed on a print substrate 6b and coil pieces K1-K36 are formed by e.g. 1/3 pitch of a pole pitch (180 deg. electric angle) of a magnetic pole for speed detection 2b of a magnet 2. Accordingly, the tertiary higher harmonic included in a magnetic flux distribution waveform of the magnet corresponds to the coil piece in the same pitch because three coil pieces correspond to one piece of the pole 2b. Consequently, an output added the electromotive force which is induced in each coil piece, is taken out from an output terminal Kout. This output can be made higher frequency than conventional frequency corresponding to a fundamental wave. Also, the pitch corresponding to a higher harmonic can be specified.

Abstract: PURPOSE:To monitor the life condition at a remote position by detecting the catalyst reaction heat of generated gas. CONSTITUTION:In a gas absorber 1, platinum catalyst such as palladium and the like making oxygen and hydrogen gas react is stored. The absorber 1 is set at a liquid port 9 of a storage battery 9, and the catalyst reaction heat is detected by a temperature sensor 10. The catalyst reaction gradually decreases due to the oxygen from a storage battery 3 or antimony in the generated gas, poisonous substance such as arsenic. The substance is generated when a lead base is electrolytically corroded, and the rate of generation is in proportion to the rate of overcharge. Since the catalysis reaction is heat reaction, the temperature of the catalyst is converted into an electric signal, which is sent to a display 12 through an amplifier 11, and the life conditions of the battery is displayed. When the corrosion conditions at the lattice of lead base of battery 3 is remarkable, the poisonous rate of catalyst increases and the decrease in the catalyst reaction is detected in terms of temperature, thereby it is detected that the end of service life of battery 3 is near and the conditions can be monitored in this way.
