Title: Solar light collector
Inventor: IMANI KAZUTAKE
IPC: F24S50/20
Filed: 1983-10-26
Abstract: PURPOSE:To simplify the sun tracking mechanism by mounting a reflecting mirror in a vacuum glass tube so as to be rotatable around a heat collecting tube, and utilizing the difference of the electric outputs of even number of solar cells in the tube, thereby eliminating the influence of atmospheric air. CONSTITUTION:The light ray form the sum 1 is collected to a heat collecting tube 4 by a reflecting mirror 3 which rotates around the heat collecting tube secured to the interior of a vacuum glass tube 2. Solar cells 6 mounted perpendicularly to the solar light and two solar cells 7, 8 inclined to the symmetrical position rotate together with the reflecting mirror. A stationary coil 9 utilizes the electric outputs of the solar cells 6 to magnetize a core 3, but they do not relatively displace from the glass tube by fittings 12. A coil 10 is magnetized by the output of the solar cell 7, and a coil 11 is magnetized by the solar cell 8. The both coils 10, 11 are secured to the end of the mirror, and produces a rotary torque in a differential transformer type by utilizing the difference of the attracting force of the coil 9.

Title: Indirect injection internal combustion engine
Inventor: KATAYAMA TOSHIKAZU
IPC: F02B19/14
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To uniformize formation of an air-fuel mixture of fuel and air, and improve a fuel consumption rate by respectively boring cross-sectional areas of these upstream auxiliary chamber nozzle ports in proportion to divided areas when a main combustion chamber is divided into the areas surrounded by the center line between mutually adjacent auxiliary chamber nozzle ports and an outer peripheral line of a piston cavity. SOLUTION: Auxiliary chamber nozzle ports 7 are divided into (71 to 76) from the cylinder center side. The cross-sectional areas of the auxiliary chamber nozzle ports 7 are determined so that the main combustion chamber divided areas 51 to 56 surrounded by the center line between mutually adjacent auxiliary chamber nozzle ports 7 and the outer periphery of a piston cavity and the nozzle port cross-sectional areas 71 to 76 become (the main combustion chamber divided area 51/the nozzle port cross-sectional area 71 = the divided area 52/the cross-sectional area 72 =...= the divided area 56/the cross-sectional area 76).  Therefore, since the divided areas of a main combustion chamber 5 per respective nozzle port cross sectional areas in proportion to injection fuel become equal to each other, the ratio of unburnt gas to air of the main combustion chamber 5 becomes equal with respective nozzle ports, and the uniform air-fuel ratio is obtained, and fuel can be excellently burnt.

IPC: F04F1/18
Filed: 1981-12-11
Abstract: PURPOSE:To make it possible to smoothly and surely perform a pumping work by forming a cylindrical body with a plural number of cylinders whose diameters become successively larger upward so as to provide the larger upper part cross areas thereof and reducing as much as possible the frictional force between a lump of air jetted and raised within the cylindrical body and the inner wall of the cylindrical body. CONSTITUTION:When compressed air is sent from an air supply pipe 15, it enters from an external storage chamber 12 through a vent 14 to an internal storage chamber 11, and is stored while forcing down the water in both these chambers 11, 12. And when the level of the water gradually descends and reaches the lower end edge of a blow pipe 10, the compressed air that has been stored in the internal and external storage chambers 11, 12 is forced out at a stretch from the inside of the blow pipe 10 to a cylinder 5. And, said compressed air rises in the cylinders 5', 5'' rapidly forming a lump of air, and explosively rushes out of the upper end of the cylindrical body 4 to force out and pump the polluted water in the cylindrical body, while simultaneously with this pumping new polluted water is absorved frorm a water absorption hole 8 into the cylindrical body 4. In that case, the lump of air rises in the cylinders 5, 5', 5'' respectively having the diameters that become successively larger from the lower one to the upper one of them, so that the frictional resistance between the lump of air and the wall surface of the cylindrical body 4 is reduced, allowing a pumping action to be smoothly and surely performed.
