Title: Bathtub device
Inventor: SUGAWARA NORIO
IPC: A61H9/00
Filed: 1990-02-21
Abstract: PURPOSE:To allow water cold or hot to fall from a high place and permit a person to feel that he is strucken by a water fall, by furnishing a discharge pillar being divergent from a selector valve installed on the discharge side of a pump, and expanding or contracting this discharge pillar with the water pressure in the direction up and down. CONSTITUTION:When a pump 4 is operated, hot water in a bathtub 1 is blown in from a suction hole 3 and passes through a selector valve 5 to flow to a blowout hole 2 or the discharge hole 8 of a discharge pillar 12. When this selector valve 5 is switched to the discharge side in order to make fall hot water onto the shoulder or the like of a user, the hot water intrudes to the discharge pillar 12 upon adjustment of its rate of flow by a flow adjusting valve 7. The hot water having intruded into the discharge pillar 12 runs against a throttle 13, and the water pressure generated thereby slides cylindrical members 9, 10, 11 so as to stretch upward as indicated by dotted line in the attached illustration, to cause jetting out of the discharge hole 8. According to this arrangement in which the discharge pillar 12 is furnished being divergent from the selector valve 5 and a throttle is installed at the discharge 8 of the discharge pillar 8, the discharge pillar 12 is expanded and contracted up and down by the water pressure, and the height of the discharge hole 8, i.e. the intensity of the hot water, can be made variable.

Title: Gain controller
Inventor: IKEGAMI ICHIROU
IPC: H04N5/52
Filed: 1981-03-18
Abstract: PURPOSE:To reduce the dynamic range as an input stage which is used to transmit the signal to a control circuit part, by securing the dynamic range to  the input signal with use of a PNP transistor differential amplifier having an  active load. CONSTITUTION:The constant current source of a diode D8 plus transistors Q10 and Q11 applies the DC current to differential amplifiers Q12 and Q13, and the input signal S1 has no relation with the current source. And the DC voltage required at that pat is set nearly at 0.75V. On the other hand, the collectors of the Q12 and Q13 drive active diodes D6 and D7 by the current. Thus the forward voltage of the D6 and D7 is enough with about 0.75V. Accordingly the voltage that is available for the differential amplifiers Q12 ans Q13 is shown as VCC- (VDS+VD6)=TCC-1.5V, and a margin is obtained for the voltage by an amount equivalent to the differential voltage. The voltage obtained by subtracting the base-emitter voltage of the Q12 and Q13 from the differential voltage is equal to the dynamic range to the signal S1.
