Abstract: PURPOSE:To prevent the solar battery ventilating device from invasion of wind and rain and permit stabilized operation by a method wherein a solar battery panel is provided pivotably on an opening at the outside of a building and a shutter, capable of being closed when the device is not being used, is mounted at the inside of the solar battery panel. CONSTITUTION:The solar battery panel body 6 is pivoted to face it toward a direction capable of receiving efficient illumination and the shutter plates 10 are opened to the positions shown by dotted lines by the air pressure from a ventilating unit 5 to project them out of a main body 4. The amount of protrusion of a mounting section is formed so as to be equal to the amount of protrusion of the shutter plates 10 substantially. When the solar battery panel body 6 is pivoted until the panel is brought to a position parallel to the main body 4, the shutter plates 10 abut against the panel 6, however, the solar battery panel body 6 is pivoted to the slanted condition thereof, shown by dotted lines in the diagram, or more slanted condition when the panel is being used. Accordingly, the minimum slanted condition of the panel body 6 is secured and the amount of protrusion of the mounting section 46, in which the panel is not abutted against the shutter plates 10, is designed in the design thereof. Thus, the invasion of wind and rain may be prevented by the shutter body, projection of solar beams against the panel body may be effected well and the stabilized operation may be effected.

IPC: F02M25/08
Filed: 1984-06-14
Abstract: PURPOSE:To ensure high efficiency of purification and prevent fuel vapor from being emitted to the atmosphere, by closing a purge controlling solenoid valve when a feedback quantity on the basis of an output signal from an exhaust gas sensor exceeds upper and lower limit decision levels. CONSTITUTION:A purge controlling solenoid valve 16 is provided in a vaporized fuel purging passage 15 connecting a vaporized fuel adsorbing device 9 with an engine intake air passage 2.

Title: Ignition timing control device for internal combustion engine
Inventor: NAKANO KAZUMI
IPC: F02P3/04
Filed: 1986-05-27
Abstract: PURPOSE:To securely prevent the erroneous detection of engine stall due to a rotation error on a high speed side by cutting off a power transistor when the lowering quantity of engine speed gets larger than a set value which is varied in accordance with said engine speed. CONSTITUTION:In an engine control device 10, a hard/soft switchover circuit 13 is switched over to either of a hard ignition or a soft ignition by means of a switchover signal from a CPU 14. That is, when the lowering quantity of engine speed is larger than the number of revolutions for judging hard ignition switchover which is obtained by multiplying an engine speed calculated from a rotation angle sensor 1 by a factor and tending to engine stall, a hard ignition is set and a transistor 15 is cut off, thereby, preventing the heat generation of the power transistor 15 and an ignition coil 20. Thus, since the number of revolutions for judging hard ignition switchover is varied by the engine speed, the erroneous detection of engine stall due to a rotation error on a high speed side can be securely prevented.

Title: Gasification combined cycle power generation plant for removal of carbon dioxide
Inventor: ABE TAKAYUKI
IPC: F02C3/28
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To maintain high efficiency of the plant, providing easy regeneration of collected carbon dioxide gas, and eliminating the necessity of a special CO2 removing equipment. SOLUTION: This combined cycle power generation plant is composed of a gasification furnace 1, a low-pressure type air separation equipment 10, a gas turbine power generation equipment 12, a water separation equipment 14, a mixture gas supply line 16, a CO2 treatment equipment 18, and an oxygen compressor 20. The gasification furnace gasifies the fuel with high-pressure oxygen. The air separation equipment separates the air into oxygen and nitrogen. In the power generation equipment, the mixture of oxygen and CO2 is compressed, the gas which is generated in the gasification furnace and purified by the gas purifier is burned in the compressed mixture gas, and power is generated by collecting the power from the generated combustion gas. The water separating equipment condenses and separates the moisture included in exhaust gas from the gas turbine power generation equipment 12.  The mixture gas supply line 16 mixes the CO2 gas coming out of the water separation equipment 14 with the O2 separated by the air separation equipment 10, supplying the mixture gas to the gas turbine power generation equipment 12. The CO2 treatment equipment 18 is disposed in the down stream of the water separation equipment. The O2 compressor compresses the O2 separated at the air separation equipment 10 to be further pressurized. Since nitrogen in the air does not enter the system, the exhaust gas is almost pure CO2 . This facilitates treatment thereof.
