Filed: 1995-06-26
Abstract: PURPOSE: To make the efficiency of AC generation high and to prolong the lives of cells, by providing a capacitor or battery in parallel to killed cells and storing energy, discharging it adding it to their output when the cells are made alive. CONSTITUTION: Cells 4 and 5 for obtaining positive and reverse outputs by the irradiation of light, heat, cosmic energy, etc., are arranged on divided-into- four circles having a center at a shaft 12, and magnetic poles 14 having coils 13 for causing their currents to flow are provided corresponding to the cells arranged on the divided-into-four circles, and permanent magnets 15 which rotate around the shaft 12 as a center by attraction or repulsion corresponding to the magnetic poles 14 are arranged. Generated power of cells 17 is charged in a capacitor or battery when light to the cells 4 is shut, and generated power of cells 18 is charged in a capacitor or battery when light to the cells 5 is shut. When the cells 5 are irradiated the outputs of the cells 18 and discharge from the capacitor or battery flow into the coil 13.  As the result, the lives become long since the cells do not deteriorate. Energy efficiency becomes high since an AC can be obtained directly without a converter.

Title: High sensitivity light receiving element
Inventor: KOYAMA KOICHI
IPC: G01J1/02
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To attain quick response and excellent stability by providing a transparent electrode, an ion conductive electrolyte and a semiconductor electrode and outputting a time differential photoelectric response for a variation in the quantity of light. SOLUTION: The high sensitivity light receiving element comprises a transparent electrode 1 and a working electrode, i.e., a silicon electrode 3, sandwiching an ion conductive electrolyte 2 between them and an oscilloscope 8 is connected between the output terminals 6, 7 thereof. When the transparent electrode 1a side is irradiated with a visible light, after quick rising of a photocurrent is observed in an external circuit before the photocurrent is returned, back to 0 level as it is and when the light is turned off, the photocurrent is deflected reversely and returned back to the original level. In other words, the light receiving element has a so-called a time differential response.  If an n-type silicon electrode 3 is employed, electrons migrate from the ion conductive electrolyte 2 (the silicon electrode 3) to the silicon electrode 3 (the ion conductive electrolyte 2) when the light is turned on (off). According to the structure, the sensitivity is enhanced by a factor of three figures, the response sped is enhanced by a factor of one figure or more resulting in quick response and excellent stability.

Title: Electron gun for picture tube
Inventor: SHIRAI MASAJI
IPC: H01J29/48
Filed: 1983-10-19
Abstract: PURPOSE:To decrease spherical aberration by extending the effective electrode diameter of a UPF type electron gun near to the inner diameter of the neck portion of a cathode-ray tube. CONSTITUTION:In extending the electrode diameter of an electron gun, an electrode supporting rod is an obstacle matter in the direction where the electrode supporting rod is present 'vertical direction', however, in the direction at a right angle to the above direction 'horizontal direction', the electrode diameter can be extended near to the inner diameter of the neck portion of a glass surrounding case 1. In the vertical direction where electrode diameter is small, the distance between acceleration electrodes 7, 9 is shortened, and in the horizontal direction, the distance is extended. Then, astigmatism of a lens can be removed and a larger aperture can be obtained, and resolution is improved. In this type of electron gun, as acceleration electrodes 7, 9 are put in a focusing electrode 8, lens intensity can be controlled by the distance between acceleration electrodes, and even if focusing voltage is extremely low, proper value can be kept in the lens.
