Title: Knocking detector for internal combustion engine
Inventor: YAMAGUCHI KIMIAKI
IPC: G01H11/02
Filed: 1979-08-28
Abstract: PURPOSE: To enable detection of knocking easily and accurately by detecting magnetic resistance variation corresponding to the variation in the gap between a vibration plate resonating with the knocking and a barlike magnetic body by a coil.  
     CONSTITUTION: Knocking vibration is transmitted to the vibration plate 21 secured to the magnetic body 23 and having a resonance characteristic through a housing 27 of a detector 2 screwed into a cylinder block and the barlike magnetic body 23. Accordingly, the vibration plate 21 generates a resonance vibration, and the gap between a barlike magnet 22 and the vibration plate 21 varies to vary the magnetic resistance of a magnetic path formed by the magnet 22, magnetic body 23, vibration plate and the like. The magnetic flux corresponding to the variation proportional to the knocking is detected by a coil 25 having a low impedance. Accordingly, the detection of the knocking can be performed accurately by a simple construction.

Title: Voice signal insertion circuit
Inventor: MATSUMOTO YOSHIAKI
IPC: H04H60/04
Filed: 1987-04-30
Abstract: PURPOSE:To insert voice signals of all stations desiring the insertion without overload by multiplying an insertion signal with a coefficient being <=1 and adding the result to the voice signal of a main transmission line. CONSTITUTION:A voice signal inputted to an input terminal 102 becomes the 2nd input of an adder 1 via a coefficient device 2. Thus, the sum of the voice signal and the insertion signal of the main transmission line is outputted from the adder 1 and this signal is outputted to an output terminal 103. The coefficient device 2 gives a degree of loss to the insertion signal so as to prevent an adder 3 from being overloaded. Thus, the insertion and transmission of the voice signal are attained without causing overload from an optional station.

Title: Motor driving circuit
Inventor: OIWA SHOJI
IPC: H02P8/12
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a driving circuit of a motor which can limit charging current with small number of components and which requires only a small space and can increase the motor efficiency by allowing charging current of an electrolytic capacitor to flow through an upper or a lower arm transistor which constitutes an H-bridge and a resistor for detecting a motor winding current and thereby building up a current limiting circuit with these components. SOLUTION: When a power switch 12 is turned on, for examle, an upper transistor 2 comes to an ON state and charging current id is caused to flow through the transistor 2 and a diode 9. The current id passes through a resistor 14 for detecting a current, where the current is converted into voltage, and then the voltage is compared with the reference voltage by means of a comparator 15. In the case that current of the set value or above is caused to flow, an output signal from a logic circuit 7 is cut off to stop the flow of charging current into an electrolytic capacitor 13. When the current in the resistor 14 for detecting a current decreases, the electrolytic capacitor 13 is supplied with charging current again. When charging comes near to completion, a motor winding 5 is also starts to be excited.  The sum of the charging current id and the exciting current for the motor winding 5 is kept at the set value.
