Title: Attitude controllor for antenna on moving body
Inventor: KATO EIJI
IPC: G01S3/44
Filed: 1990-11-30
Abstract: PURPOSE:To make it possible to correct the attitude of an antenna not only in the direction of the yaw angle of a moving body but also in the directions of a roll angle and a pitch angle by using only an attitude-change detecting mechanism in the direction of the yaw angle. CONSTITUTION:A first control means 4 corrects the antenna attitude through driving means 141 and 151 in the offsetting direction of the attitude deviation of a BS antenna Ant with respect to a radiowave source in response to the attitude change Yas detected with a yaw-attitude-change detecting means 30, the attitude change in the roll-angle direction operated with a first operating means 4 and the attitude change in the pitch-angle direction operated with a second operating means 4. Thus, the attitude-change data in the yaw-angle direction in the roll-angle direction and in the pitch-angle direction are obtained only with the mechanism of the yaw-angle-change detecting means 30. The attitude of the antenna Ant is corrected in azimuth and in elevation in response to the data.

Title: Method and device for superconducting multilevel recording and reproducing
Inventor: KATO TADASHI
IPC: G11B5/02
Filed: 1987-12-28
Abstract: PURPOSE:To enable the multilevel recording and reproducing of the unit of magnetic flux quantum by performing the multilevel recording and reproducing at the unit of the magnetic flux quantum by controlling the number and the direction of the magnetic flux quantum to be pinned on a recording medium. CONSTITUTION:When a magnetic field is impressed to the recording medium 10 and simultaneously, light is converged and projected from an objective lens 4, because the temperature of an irradiated part rises and exceeds a critical temperature, a magnetic flux intrudes inside a superconducting thin film 11. Next, when the projection of the light is stopped, the temperature of said part drops, and at last, it comes below the critical temperature, and a superconductive state is restored, and at that time, a part of the magnetic flux having intruded in the superconducting thin film 11 is pinned at a pinning center such as the lattice defect, etc., of the superconducting thin film 11, and is held in the recording medium even if the magnetic field is removed. Accordingly, by controlling the number and the direction of the magnetic flux quantum to be pinned at the lattice defect, etc., by changing the magnitude and the direction of a current to be flown in a recording head, information recording at multi-level can be performed. Thus, the multi-level information recording/reproducing can be performed.

Title: Discharge lamp lighting device
Inventor: URATANI KAZUYUKI
IPC: H05B41/39
Filed: 1988-12-28
Abstract: PURPOSE:To enable a deep dimming and to obtain a dimming lighting in a wide scope by providing a high-frequency wave generator to apply a relatively high-frequency of voltage to a discharge lamp only for a specific period from the initial time of a half cycle at every half cycle of a rectangular wave AC voltage. CONSTITUTION:An inverter 1 outputs a rectangular wave AC voltage of a relatively low frequency. And a high-frequency wave generator 6 applies a relatively high frequency voltage to a discharge lamp 2. That is, while the discharge lamp 2 is enforced by a rectangular wave AC voltage, a relatively high frequency voltage is applied to the discharge lamp 2 for a specific period from the initial time of every half cycle at every half cycle of the rectangular wave voltage. Since the current valve of the rectangular wave voltage is controlled in such a way, the discharge lamp is never put out even though a deep dimming control is carried out, and the high-frequency lamp current owing to the high-frequency voltage is never increased to disturb the dimming lighting. Consequently, a deep dimming of the discharge lamp can be carried out, and the dimming in a wide scope is realized.

Title: Electron beam irradiating method, cross-linking or curing method, and object irradiated with electron beam
Inventor: KUWABARA MASAMI
IPC: C08J3/28
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To produce a variation in the state of cross-linking or curing of an object irradiated with an electron beam without homogeneously cross-linking or curing the object as a whole by irradiating the object with an electron beam by using a specific electron beam radiation apparatus. SOLUTION: A distribution of cross-link density, hardness, or degree of modification is formed in the thickness direction of an object by the irradiation with an electron beam. This irradiation is performed with a vacuum-tube electron beam radiation apparatus. Since this apparatus operates at a low acceleration voltage, the reachable depth of an electron beam is low, and since the acceleration voltage is easily controllable, the reachable depth of an electron beam can be easily controlled. In order to form a gradation structure or a layered structure without fail, the object is pref. thermally treated after partially cross- linked or cured in the thickness direction. The radiation voltage of the electron beam is pref. 100kV or lower in terms of controlling the reachable depth. The thickness of the object is pref. 10μm or higher.

Title: Movement detecting device for moving body
Inventor: HAKAMATA KAZUO
IPC: G01P3/486
Filed: 1989-12-26
Abstract: PURPOSE:To detect the movement and direction of the reciprocal moving body by detecting light which is made incident on two optical waveguide members individually as the reciprocal moving body moves, and deciding the photodetected outputs. CONSTITUTION:When a moving body which is not shown moves, a projection part 55 moves in the lengthwise direction of converging rods 56a and 56b. The surfaces 75a and 75b of the converging rods 56a and 56b are scanned with the laser light 58 from the projection part 56, and the parts of masks 61a and 61b and slit parts where the masks 61a and 61b are not provided are irradiated alternately. The light 58 irradiating the slit parts is made incident on the converging rods 56a and 56b and reflected totally by the interfaces between their surfaces and a circumferential medium to travel toward end surfaces 76a and 76b. The laser light 58 which is thus propagated is detected by photodetectors 62a and 62b. When the laser light irradiates the masks 61a and 61b, on the other hand, the light is cut off by the masks 61a and 61b and the outputs of the detectors 62a and 62b vary, so the movement of the moving base can be detected.
