Title: Internal leakage detecting system for hydraulic cylinder
Inventor: KANEHARA MASAKI
IPC: G01M3/26
Filed: 1984-08-28
Abstract: PURPOSE:To enable easily to judge the internal leakage of a hydraulic cylinder by detecting the pressure at the head-side chamber and that at the rod-side chamber of a hydraulic cylinder so as to output an internal leakage signal when the pressure difference between the pressure at the head-side chamber and that at the rod-side chamber is a prescribed value or less. CONSTITUTION:Each of the pressures at the head-side chamber 2h and that at the rod-side chamber 2r of a hydraulic cylinder 2 is detected by pressure detectors 5h and 5r respectively. And the detected pressure signals are input into an input part 6, and, after they have been converted into a digital signal, the difference of both pressure signals is calculated in an arithmetic part 7 and the difference value thus obtained is compared with a prescribed value. In this case, if any abnormality exists in the piston packing of the hydraulic cylinder 2, the oil pressure in both chambers 2h and 2r becomes equal since oil in the head-side chamber 2h leaks into the rod-side chamber 2r. Accordingly, when the remainder after the detected value of pressure detector 5r is subtracted from that of pressure detector 5h is a prescribed value or less, an internal leakage signal is output from the arithmetic part 7 to an indicating part 8.

Abstract: PURPOSE:To provide a burning method of producing bunst products from incineration ash from which is has been conventionally difficult to produce burnt products. CONSTITUTION:This burning method of refuse incineration ash is to add glass cullet to a refuse-incineration ash, then knead the mixture with an added binder and water and burn a molded mixture product after its mixing process. In concrete terms, the refuse-incineration ash, if containing water, is dried and crushed to the grain diametral size of about 4mm or less. Glass cullet, crushed to the size of about 1mm or less, is mixed at a radio of 10 to 30 pts.wt. for 80 to 50 pts.wt. of refuse-incineration ash. Further, this mixture is compressed into a molded product at a pressure of 500 to 1000kg.f/cm<2>, and is burned at a temperature range of 850 to 1,150 deg.C.

Title: Delay circuit
Inventor: KANAZAWA TAKESHI
IPC: H03K5/13
Filed: 1988-07-15
Abstract: PURPOSE:To construct the title circuit cheaply in a small space by obtaining a delay time twice as much as the inherent delay time of a reference delay circuit at the rise of an input signal by only one set of the reference delay circuit. CONSTITUTION:The title circuit is equipped with a reference delay circuit 1, a latch circuit 8 to hold the output of the reference delay circuit 1 if necessary and a polarity inverting circuit 9 to invert the polarity of the signal of an external input terminal by the output of the latch circuit 8. By holding temporarily the output of the reference delay circuit 1, the latch circuit 8 changes the output to the polarity inverting circuit 9 connected to the input of the delay circuit 1 and the external output of the latch circuit 8 only in case of need. Consequently, by one delay circuit, the delay time twice as much as the delay time of the delay circuit can be obtained. Thus, the circuit can be constructed inexpensively in a small space.

Title: Dc high-voltage power source
Inventor: OSANAI KATSUTOYO
IPC: H02M7/10
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To reduce wasteful electric power consumed inside a power supply. SOLUTION: Respective connecting points of a smoothing capacitor CF, connected in series and a capacitor C for Cockcroft-Walton type boosting circuit, are connected through a high resistor RB, and with a DC voltage existing at the respective stages of the boosting circuit given to the connecting point of the smoothing capacitor, and the potential of the smoothing capacitor is determined. Thus a breeder resistor, which was necessary hitherto for giving the voltage divided by parallel connection with the smoothing capacitor to the respective smoothing capacitors, is dispensed with. Also electric power consumed inside the power source is reduced, because no wasteful breeder current flows.

Abstract: PROBLEM TO BE SOLVED: To obtain a multichannel flaw detecting method which does not require much time to eliminate an irregularity in the flaw detecting characteristic between channels and which prevents the time resolution of an echo from being degraded. SOLUTION: A first process (S1 to S3) is executed in such a way that an initial transmitting signal in a prescribed waveform is transmitted to an object, to be detected, in every channel out of multichannels via an ultrasonic probe in the channel, and that the frequency characteristic of the ultrasonic probe in the channel is found on the basis of a signal which comprises its echo signal and on the basis of the initial transmitting signal. A second process (S4 to S6) is executed in such a way that the frequency range of an ideal waveform on the basis of the found frequency characteristic is decided so as to find the ideal waveform and that the filter characteristic of the channel is found so as to make the echo waveform of the channel the ideal waveform.  A third process (S7) is executed in such a way that a filter treatment by the found filter characteristic is executed to an echo signal, to be compressed, in the channel or to the initial transmitting signal. After that, a flaw detecting operation by the multichannels is executed.

Filed: 1988-07-19
Abstract: PURPOSE: To shorten the length of the longitudinal axis of a nozzle while holding a good signal generating function by coupling a needle valve and a spring member provided between the needle valve and a movable element, through a traction connection with a clearance. CONSTITUTION: A coiled compression spring 38 provided within a spring chamber 22 formed inside of an injection nozzle holder 10 is coupled with a needle valve 15 by way of pressurizing member 20 to be connected through traction with a clearance to a pressurizing pin 19 and is engaged with a movable body 32.

Immediately after a release stroke starting, as the initial gap between the movable body 32 and the magnetic core 30 is reduced to zero, a clear variation can be recognized in the created voltage. In the case of a closure stroke, when the movable body 32 is kept away from the magnetic core 30, a clear signal is again transmitted to the evaluation circuit.  When the injection nozzle is constructed in the manner as described above, the length of the nozzle can be shortened without losing a good signal transmitting function.

IPC: G07D1/00
Filed: 1994-07-29
Abstract: PURPOSE:To reduce a load on a coin pay-out motor and to speedily pay out change coins by controlling a projection protruding and retracting means arranged for each rotary cam. CONSTITUTION:When coins are paid out, the projections 20a-24a of rotary cams 20-24 are retracted into the corresponding cam grooves 12-16 of pay-out slides 2-6 corresponding to the coins to be paid out through projection protruding and retracting means 50 arranged by the rotary cams 20-24. Therefore, plural kind of coins can be paid out at the same time by driving plural pay-out slides at the same time. When no coin is paid out, the projections 20a-24a of the rotary cams 20-24 are protruded from the corresponding cam grooves 12-16 of the pay-out slides 2-6 through the projection protruding and retracting means 50. Therefore, the rotation of the rotary cams 20-24 is maintained to cut off the transmission of a driving force to the pay-out slides 2-6, and consequently no load is placed on the coin pay-out motor 30 which transmits the driving force to the rotary cams 20-24.
