Title: Controller for generator for water stream containing bubble
Inventor: SONEDAKA KAZUNORI
IPC: F24H9/00
Filed: 1992-09-01
Abstract: PURPOSE:To secure safety and protection of water circuits by detecting the abnormality of the water circuits. CONSTITUTION:By a pump 5, water is allowed to circulate in a circulating water circuit part A and part thereof is discharged into a water tank 1 through a feed pipe line 3. Air from an air inflow device 16 and the water from the water tank 1 through a return pipe line 18 are led into the circulating water circuit part by the action of a negative pressure part 8a, which action is caused by circulating-water in an ejector part 8. Therefore, the air is pressurized and solubilized in the water by the pump 5, is depressurized through the feed pipe line 3 and is discharged into the water tank 1, and thus a water stream containing bubbles is generated. A controlling means 21 controls the operation of producing the water stream containing the bubbles. In addition, by the controlling means 21, the air inflow device 16 is opened and the air is allowed to flow-in when a pressure-detecting part 14 detects a normal pressure in the feed pipe line 3. When the pressure becomes abnormal, an opening and shutting device 20 for discharging water in which the air is mixed is opened, and abnormal pressure and the water are relieved to the water tank 1 through a branch line 19 and the operation of the pump 5 is also stopped. Therefore, the pump 5, the circulating water circuit part A, the feed pipe line 3, the return pipe line 18 and so on can be protected against the abnormal pressure.

Abstract: PROBLEM TO BE SOLVED: To improve operability and exterior design by facilitating the removal of a separation-type battery pack used for a portable telephone. SOLUTION: When a hook portion 60 of the bottom of a battery pack 50 is engaged with the recessed part 35 of the bottom of a portable telephone body 10 and then the battery pack 50 is pressed into the portable telephone body 10, a slide claw 21 which is integrally constituted with a slide knob 20 is engaged with the recessed part of the head portion of the battery pack 50 to be fixed. When the slide knob 20 is pulled out, engagement between the slide claw 21 of the slide knob 20 and the recessed part of the head portion of the battery pack 50 is released, a slide projection 22 constituted integrally with the slide knob 20 is brought to contact a projection 70 of the back surface of the head portion of the battery pack 50 to forcibly press up the battery pack 50 to push up the battery pack 50. Thus, the battery pack 50 can be easily removed from the portable telephone body 10, and since projections for the removal of the battery pack is not required to be provided for the battery pack, exterior design of the battery pack is also made neat.

IPC: F02D41/00
Filed: 1986-10-03
Abstract: PURPOSE:To enable shortening of a time required for starting of self-running of an engine, by providing a valve device which is temporarily communicated with a small volume pressure accumulating chamber before cranking of a large volume pressure accumulating chamber during the starting of an engine. CONSTITUTION:When an ignition switch 58 turned ON to start an engine, a second shut-off valve 23 is opened by means of a signal from a control unit 40. Since high pressure fuel stored in a large volume fuel pressure accumulating chamber 14 is fed in a small volume fuel pressure accumulating chamber 12, the small volume fuel pressure accumulating chamber 12 is filled with high pressure fuel. Thus, with a starter motor run, a fuel pressure in the small volume fuel pressure accumulating chamber 12 is immediately increased to a value higher than a set pressure necessary to injection, and thus, an engine can be started in a short time. During running of an engine, the small volume fuel pressure accumulating chamber 12 and the large volume fuel pressure accumulating chamber 14 perform function of an injection pressure accumulating chamber having a single high volume.

Abstract: PURPOSE:To prevent the hang-up or the system down of the titled system by outputting a pseudo interruption response signal from a time supervision part to a peripheral equipment control part when prescribed time is elapsed after outputting an access request signal in case an interruption response signal is not outputted from a peripheral equipment. CONSTITUTION:If an access request signal is outputted from the peripheral equipment control part 4 to the peripheral equipment 3, the time supervision part 5 is triggered at the output timing of the said signal. If the peripheral equipment 3 operates normally and outputs an interruption response signal to the peripheral equipment control part 4 in response to the access request signal, the time supervision part 5 is reset at the timing of the output of the access request signal. On the other hand, in case the interruption response signal is not outputted to the control part 4 because the peripheral equipment 3 does not normally operate due to such as the status of errors, the time supervision part 5 is triggered and the prescribed time lapses, the part 5 outputs a pseudo interruption response signal to the peripheral equipment control part 4. As a result, the hangup or the system down of the titled system can be prevented.
