Title: Health care device
Inventor: KUNITAKE YASUHIRO
IPC: G01N33/493
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To prevent residual liquid in a transporting passage from leaking, even when a sensor for measuring physical quantity of excreta provided in a stool is removed, by interposing the sensor at a position having the highest potential energy in the transporting passage. SOLUTION: In a urine examining device 10, a urine sampling arm 32 of a urine sampling unit 12 mounted to a rim of a western-style stool samples discharged urine of a user, and a feeds it to a measuring unit 11 installed on a floor. After a rotary valve syringe 18 communicates a port of a starter with a buffer liquid port to suck buffer liquid, the measuring unit 11 communicates with a port of a transporting tube 150 connected to the inlet of a urine sensor 28, charges the buffer liquid into the transporting tube 150 and a tube 152, and feeds urine to the urine sensor 28 via the buffer liquid. The urine sensor 28 specifically identifies glucose (grape sugar) from many components, and converts it to an electric signal. Because the urine sensor 28 is placed at a position having a potential energy higher than those of both tubes 150, 152, its removal does not cause leakage of liquid.

Title: Excessive input signal preventive system
Inventor: YOSHII KUNIKATSU
IPC: H03G3/34
Filed: 1979-04-17
Abstract: PURPOSE:Not to cause an excessive input in the post-amplifier even the status has been varied from non-input to availabe input, by delaying and controlling a signal by the pre-amplifier when the signal has been input. CONSTITUTION:In case of the status that a signal is not input, the post-circuit is disconnected by the switch SW, and only the pre-circuit is operated. When an input signal has been generated, the squelch circuit 6 is opened, and the switch SW is closed after a fixed period of time by the delay circuit 9. In this delay time the automatic gain control system AGC1 shows the effect and controls the amplifier 3 so that an output signal from the switch to the pre-circuit can be controlled. Accordingly, it is possible to suppress generation of a noise due to an excessive input which has been generated in its head part when the input signal has been generated.

Title: Noise reducing method of press machine and its device
Inventor: ABE TOSHIO
IPC: B30B15/02
Filed: 1981-03-31
Abstract: PURPOSE:To reduce a noise generated when a cushion pin hits against a die- cushion pad in case of starting a machine, by providing a pre-cushion pin mechanism on the bolster of a press machine. CONSTITUTION:A pre-cushion pin mechanism is installed to a bolster 6 of a press machine. When a slide 3 goes down in case of starting a press machine, at first, a pre-cushion pin goes down, and its lower end pushes a die-cushion pad 5, and makes the slide 3 go down softly. Subsequently, the slide 5 interferes with a cushion pin 7, makes the cushion pin 7 go down, and hits against the die- cushion pad 5. That is to say, it is prevented that a maximum load is applied from the beginning at the moment when the cushion pin 7 hits against the die- cushion pad 5, a pre-cushion is given by the cushion mechanism. Therefore, it is possible to remarkably reduce a noise generated when the cushion pin 7 hits against the die-cushion pad 5 with a maximum load.
