Title: Synchronous noise eliminator
Inventor: HITOMI JUICHI
IPC: G11B20/02
Filed: 1988-03-31
Abstract: PURPOSE:To obtain voice output with a superior S/N by obtaining an output signal except for a period where a switching noise is generated at the time of sampling a digital signal again at a frequency less than that. CONSTITUTION:A timing signal generation circuit outputs the frequency fH sufficiently higher than a signal band area and the frequency fL less than that. A demodulation and noise correction circuit digitizes the analog output of a reproducing voice signal processing circuit including a noise by an A/D converter 21, and demodulates it by a digital demodulator 22, and performs the arithmetic operation of the output of the demodulator 22 by a computing element 23. Here, only data except for the period where the switching noise exists is used, and the data sampled with the frequency fL can be obtained by adding those data. By adding those data, sampled data without having the noise can be generated. After performing the above arithmetic operation, an analog signal from which the switch-noise is eliminated can be obtained by passing the data through a D/A converter 24 and an LPF 25.

Title: Wiper control device
Inventor: OKADA KAZUYOSHI
IPC: B60S1/08
Filed: 1986-04-07
Abstract: PURPOSE:To prevent the burning of a wiper motor when a wiper is locked by providing an automatic stop switch for stopping said wiper motor and operating a fail safe function when there is no change in the signals of said automatic stop switch within a set period of time. CONSTITUTION:When an operating switch 1 is operated, a control means 6 starts the counting of a first set time T1 while detects the signal of an automatic stop switch 4 in the set time T1. As a result, when there is change in the signal, the counting of the set time T1 is reset whereas when there is no change, a fail safe function 5 is operated. Accordingly, when a wiper motor 2 gets locked, the fail safe function is operated for the first set time T1 repeatedly until the automatic stop signal is changed while the fail safe function is stopped or intermittently carried out during a second set time T2. Thereby, the wiper motor 2 can be prevented from being continuously electrified and protected.

Title: Rotation stopper for rotary coupling of air clutch
Inventor: KAMIO TAKENORI
IPC: F16D48/04
Filed: 1981-05-26
Abstract: PURPOSE:To accurately keep the outer shaft of a rotary coupling concentric to its inner shaft under resisting force at rotation, by securing a flexible hose for supplying air to an air cylinder mechanism on a clutch housing and the outer shaft of the rotary coupling. CONSTITUTION:The inner shaft 60 of a rotary coupling rotates together with a clutch cover, while the outer shaft 61 of the coupling is standstill because the outer shaft is connected to a clutch housing through a hose 17. Since the hose 17 is flexible, the outer shaft 61 is not restrained by the hose, so that the outer shaft can move in the radial direction relative to the inner shaft 60. For that reason, even if the outer shaft 61 is located eccentrically to the inner shaft 60 at the time of their assembly, the outer shaft receives strong resisting force from the inner shaft 60 at its rotation so that the outer shaft is moved and then maintained in a position which is concentric to that of the inner shaft and is such that the resisting force is minimum.

Title: Detecting circuit for abnormality of tacho-generator
Inventor: KATOU YOSHINDO
IPC: G01P3/42
Filed: 1980-06-13
Abstract: PURPOSE:To decide and detect abnormality instantaneously while enabling the stoppage of a motor by a method wherein the voltage of a motor armature and voltage generated from the tacho-generator are compared, and the presence of the abnormality of the tacho-generator is detected. CONSTITUTION:When a tacho-generator (TG) system is normal, a transistor 19 is at an off condition because voltage (the sum of armature voltage and applied voltage for compensating a voltage drop portion due to armature resistance) inputted to a terminal 17b of a comparator 17 of a TG abnormality detecting circuit 18 is larger than voltage VTG generated from the TG inputted to a terminal 17c. When abnormality generates in the TG system and VTG reaches 0, the transistor 19 is ON, the base driving of a power transistor (not shown) is interrupted, a DC motor is stopped and a light-emitting diode 20 for abnormality alarm is lit. A switch 16 is ON at the time of the operation of the DC motor and OFF at the time of stoppage, and the malfunction of the TG abnormality detecting circuit 17 at the time of the starting and stoppage of the DC motor is prevented.
