Title: Method for measuring coat thickness of cable
Inventor: HIRAI TAKESHI
IPC: G01B17/02
Filed: 1983-07-11
Abstract: PURPOSE:To measure the coat thickness of a cable highly accurately by measuring the coat thickness of the cable extruded from an extruding machine by ultrasonic sensors arranged in water at positions on the inlet and outlet sides of a water-cooled trough and correcting the measured value of the inlet side from the difference between both measured values. CONSTITUTION:The coated cable 3 extruded from the extruding machine 1 is cooled in the water-cooled trough 4. The ultrasonic sensors A, B1 on the inlet and outlet sides of the water-cooled trough are turned to the cable 3 and an ultrasonic sensor B2 is turned to a reference sample 7 consisting of the same material as the cable and already known at its thickness. A coat thickness calculating circuit 13 calculates the coat thickness from the ratio of thickness signals obtained by the sensors B1, B2 and a correcting factor calculating circuit 12 calculates the correcting factor of the sensor A and registers the calculated result in a correcting circuit 11. A switching circuit 8 is switched and then the thickness signal outputted from the sensor A is corrected by the correcting circuit 11. Consequently, the highly accurate value similar to that measured by the sensor B1 on the outlet side can be obtained by the sensor A on the inlet side of the trough.

IPC: H04J3/14
Filed: 1982-07-19
Abstract: PURPOSE:To prevent radio interference, by measuring a timewise shift between a receiving signal and a reference signal every time a receiver receives a signal from each transmitter and producing alarm when the shift exceeds a prescribed value. CONSTITUTION:Reset terminals 3a, 3b of a timer 3 of each transmitter 2 are connected to reset terminals 8a, 8b of a timer 8 of a receiver 1. After a start switch 11 of the timer 8 is depressed in this state, the timer 3 is disconnected from the timer 8. Thus, the timers 3, 8 are synchronized, an output is given from the timer 3 of the transmitter 2 at a prescribed time interval and the transmission is attained during this time. On the other hand, the timer 8 of the receiver 1 outputs the reference signal corresponding to the transmission time of the transmitter 2 and a comparison circuit 9 measures the time shift between the receiving signal and the corresponding reference signal. When this shift exceeds a prescribed value, it is discriminated that radio interference is possible and a signal is transmitted from the circuit 9 to an alarm device 10.

IPC: F02B37/00
Filed: 1978-10-14
Abstract: PURPOSE: To provide an internal combustion engine with supercharger, in which cams for driving suction and exhaust valves are formed to be used for both of supercharged and non-supercharged operation of the engine, whereby lowering of engine output can be prevented by shifting the cams to their position of non-supercharged operation when some trouble is caused with the supercharger.  
     CONSTITUTION: Cams are formed on cam shaft 2 such that they have respectively a supercharging cam portion 3 having a large overlap of the suction valve and the exhaust valve and a non-supercharging, normal cam portion 4 having a relatively small overlap of the two valves. The cam shaft 2 is designed to be shifted automatically or manually by lever 8, so that tappet 6a for driving the suction valve and the exhaust valve can be shifted between two positions of the above cam portions 3 and 4. With such an arrangement, if some trouble is caused with the supercharger, lever 8 is shifted so that tappet 6a comes into engagement with non-supercharging cam portion 4. Thus, suction valve and exhaust valve are opened and closed at the timing suited for normal non-supercharged operation of the engine.

Title: Semiconductor integrated circuit
Inventor: OGURA ISAO
IPC: G11C11/413
Filed: 1986-05-31
Abstract: PURPOSE:To enlarge a sense margin by pulling up an input signal and a reference signal respectively by individual nodes. CONSTITUTION:The respective potentials of the input signal AIN, the reference signal VR are pulled up through coupling capacitors C1, C2 by the individual nodes c, f. One of the nodes c, f goes to a high potential through a transistor Q10 controlled by a signal AIN, a charging transistor Q9, at transistor Q11 controlled by a clock, a transistor Q12 controlled by the transistors Q9, Q10 or the like, and then the other goes to a low potential. When the signal AIN goes to a high level, the capacitor C1 is pulled up and when it goes to a low level, the capacitor C2 is pulled up, the conductance of the transistors Q1, Q2 is selectively enlarged to carry out a high speed sense and at the same time, a sense margin is enlarged. Consequently, when the minute potential difference between the input signal and the reference signal is effectively detected, there is obtained a semiconductor sense circuit difficult to produce a malfunction.

Title: Water and sand ejection
Inventor: ANDOU NOBORU
IPC: B24C7/00
Filed: 1979-10-01
Abstract: PURPOSE:To simplify facilities and facilitate the operation, by opening a hose connected with a sand vessel into a nozzle which ejects a high pressure water, and sucking sand by the negative pressure induced by the ejected water. CONSTITUTION:By manipulating a trigger 27 a high pressure water is ejected through the nozzle 16 at high speed. In this case, a negative pressure is induced in the nozzle 16. Accordingly, when a spindle valve 40 is opened, by this negative pressure the sand is sucked up together with the air sucked through holes 70 and passes through a hole 72, a valve cylinder 52 and the hose 34 to reach the nozzle 16, so that the sand together with the water can be ejected toward the object. Thus since the sand is sucked by the negative pressure that is induced when the high pressure water is ejected through the nozzle, a sand carrying compressor is not required and therefore the facilities are simplified and the operation is ready.
