Title: Injecting method of solidifying material into vessel for solidification of radioactive waste and controlling device of injection
Inventor: FUKAO AKIRA
IPC: G21F9/00
Filed: 1988-12-27
Abstract: PURPOSE:To enable accurate injection of a solidifying material at an aimed level and execution of complete solidification and to prevent radioactivity from radiating from a radioactivity-contaminated substance by injecting the solidifying material in two stages with an injection flow rate being varied. CONSTITUTION:First an air-pressure cylinder 7 being driven, the fore end part 6a of a purge pipe 6 is set at a first measuring position before quantification located 60mm below the uppermost part of a processing vessel 1. Next, a control valve 14 provided at a charging port of a mixing hopper 5 is fully opened and a solidifying material is charged into the processing vessel 1 by the amount of charge of about 30l per minute. When the upper surface 4a of the solidifying material 4 reaches the vicinity of the first measuring position of the processing vessel, the pressure of air inside the purge pipe 6 rises about several millimeters by a water column. This change in the pressure is detected by a micropressure sensor 9 and the control valve 14 is restricted to reduce the amount of charge of the solidifying material into the processing vessel 2. By controlling the injection of the solidifying material in two stages in this way, overshooting of an injection level is prevented and an accurate control of the injection level is enabled.

IPC: H01L41/04
Filed: 1987-12-28
Abstract: PURPOSE:To reduce power consumption by turning on and off a transistor of a bridge circuit alternately in a pulse generation circuit to generate positive and negative pulse voltage alternately. CONSTITUTION:An inverter is constituted of an oscillation circuit 1, a driving circuit 2, a pulse generating circuit 3 and a constant voltage circuit 5. When DC voltage V1 is applied to the oscillating circuit 1, oscillation is made with a frequency according to the time constant of a capacitor Cx and resistor R, and corrugated waveform voltage is outputted from the circuit 1. The corrugated waveform voltage is inputted into the driving circuit 2, from which two operating signals Vd1-Vd2 with different operating points are outputted after a quiescent period. Those signals are inputted into each input terminal alternately, and accordingly, Tr1-Tr2 and Tr3-Tr4 of each opposite side of a bridge circuit 4 constituting the circuit 3 are turned on and off alternately. As a result, the DC voltage V2 is converted into positive and negative voltage having a pulse quiescent period, and is taken out from inter-output terminals.

Title: Hot water washing stool seat
Inventor: YAMAZAWA HIDEKI
IPC: E03D9/08
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of waste water by connecting a pressure control valve making discharge pressure constant to an original solenoid valve for performing water feeding and shielding and supplying discharge water of the pressure control valve to a heater by a water pump to jet hot water from a nozzle. SOLUTION: When backside washing is selected and operated by a washing mode button, an original solenoid valve 2 is opened by the output of a microcomputer 13, and city water flows through the original solenoid valve 2 and a pressure control valve 3. After the discharge water of the pressure control valve 3 is supplied to a heater 5 by a rotation speed coincident with the backside washing to become hot water, it is supplied to a four-way valve 11 communicating with a nozzle 12 coincident with the backside washing through a flow sensor 8 to be jetted from the nozzle 12 as washing water. Even when the inlet water pressure of water supplied from a water inlet 1 is high, the downstream pressure of the pressure control valve is operated so as to be substantially previously set water pressure.  Thus, when water energy is weakened by a water pump, the occurrence of waste water can be prevented because the pressure control valve throttles the valve.
