Title: Oil injection device for scroll compressor
Inventor: IZUNAGA YASUSHI
IPC: F04C29/04
Filed: 1989-07-26
Abstract: PURPOSE:To improve reliability through the restraint of the vibration of a piping system connecting to an oil injection hole, by opening at the lower part of a space the inlet and outlet of the buffer space provided at an injection piping system connecting to the injection hole. CONSTITUTION:When a compressor is driven, supply oil through an oil injection pipe is injected into a compression chamber 8 through an oil injection hole 15, and is mixed with operation gas, and is discharged into the upper part space 1a through a discharge hole 9 as the oil together with the operation gas becomes of high temperature and of high pressure. Next, this mixture comes to a space 1b around a motor via passages 12a, 12b, and the operation gas and the oil are separated, and the oil falls into the lower part of a sealed container 1 and is stored. Hereupon, the pulsation of pressure is generated within the hole 15, and this pulsation is conveyed through an oil injection pipe 14a to oil 16a within a buffer space 20, but as operation gas 21 occupying the upper part space of the space 20 has the property of compression, it acts on so that the pulsation of pressure may be restrained. Accordingly, the pulsation of pressure within an oil injection pipe 14b connecting to a space inlet 22, is restrained, and the vibration of a piping system can be reduced.

Abstract: PROBLEM TO BE SOLVED: To steadily disinfect water without being accompanied with malodor evolution by stopping a pump during a time when water in a container is heated by a heating means at a disinfection temperature and then starting the operation of the pump and discharging the disinfected water to a heat diffusion tank from a container. SOLUTION: A circulation pump 15 is intermittently operated by operation of a control apparatus to circulate water of a bathtub 16, which is a heat diffusion tank, to a counter flow type heat exchanger 1 and stopped during the time when the water in the inside of the housing 6 is heated at the disinfection temperature by a heating means 3. After that the circulation pump 5 is started to discharge the disinfected water out of the counter flow type heat exchanger 1 to the bathtub 16. At that time, the stop period in the intermittent operation cycles of the circulation pump 15 is set shorter in the case the heating demand of the bathtub 16 is higher. The operation of the circulation pump 15 is stopped until the temperature in the inside of the bathtub 16 becomes lower than a prescribed value after the disinfected water is discharged out of the counter flow type heat exchanger 1.

Title: Laser-diode driving circuit
Inventor: WADA TETSUO
IPC: H01S5/068
Filed: 1986-08-19
Abstract: PURPOSE:To stabilize the light output of a laser diode, by providing a feedback loop, which is constituted by a differential amplifier, an overcurrent preventing circuit having an integrating circuit constitution and a variable voltage element, which makes the source voltage Vs of an FET constant, at the source of the field effect transistor FET. CONSTITUTION:When the mark rate of an input signal (d) is fluctuated, a DC component, which flows through a source (a) of an FET 2 and is fluctuated in accordance with the fluctuation of the mark rate, is charged in a capacitor C2, which is connected to the source of the FET 2. The voltage of the source is applied to one input terminal of a differential amplifier 4. A variable voltage element 3 is controlled so that said voltage becomes equal to a reference voltage (e), which is applied to the other input terminal of the differential amplifier 4. Thus a source potential can be kept constant. An overcurrent preventing circuit 5 comprising an integrating circuit is provided between the differential amplifier 4 and the variable voltage element 3. The source potential is changed more slowly than the change in gate potential by the circuit 5 when a power source is truned ON. Thus generation of overcurrent can be prevented, and the compact, highly reliable driving circuit is obtained.

Filed: 1981-11-30
Abstract: PURPOSE:To suppress the scorching of food in moderation even if the food comes in contact with a heater, by so constituting that the heater is descended over repetition of alternate movement for ascent and descent of the heater, in a microwave oven which is served both as microwave heating and grill heating. CONSTITUTION:When microwave heating is suspended, a relay R2 is excited, a heater 8 is electrified and the heater 8 is started to descend by turning a damper 3 off. In this instance, the heater repeats its ascending and descending movements in such a manner that two steps are taken forward after a step taken backward by making a rotation of a motor 9 into forward and reverse directions alternately through alternate actuation of relays R3 and R4 to be made by instructions of a microcomputer CPU. With this, the heater 8 is descended finaly. The heater 8 is ascended through judgment that food is brought into contact with the heater 8 when terminal voltage of a gas sensor becomes extraordinary. Contact of the food with the heater is reduced and damage of the food can be made minimum through repetition of ascent and descent in little like this.
