Patent JP-H02237892-A (JP)
Title: Electromagnetic propulsion vessel
Inventor: NOMURA TOSHIHIRO
IPC: B63H11/00
Filed: 1989-03-13
Abstract: PURPOSE:To freely control the movement of a hull by forming an annular body by setting the opposed sides among a plurality of square-shaped superconductive coils 1 and arranging said annular body in a hull and arranging at least a pair of electrodes, setting contiguous to the opposed side, in the water on the outer periphery of the hull. CONSTITUTION:A triangular annular body is arranged in a hull, in the state where the opposed sides of square-shaped superconductive coils 1-3 are set contiguous. Electrodes 1A and 11A are arranged in water so as to be opposed to one opposed side 1a of the superconductive coil is through the wall of the hull. Other superconductive coils 2 and 3 are constituted similarly. When electric current flows in each superconductive coil 1-3, the coil magnetic field N is generated in the outward direction perpendicular to the coil surface, and the magnetic field between the contiguous coils is generated in the inward direction S. Therefore, the water stream in the direction perpendicular to the paper surface is generated in the sea water between the electrodes 1A and 1B and the electrodes 11A and 11B, according to the Feming's law. Therefore, the direction of the water stream can be changed in various directions according to the existence of application to each electrode and by the selection of the electrodes.

Title: Recording and reproducing device
Inventor: KOGURE MASAO
IPC: G11B27/34
Filed: 1995-02-24
Abstract: PURPOSE: To confirm whether a combine operation can be executed or not when it is put into a reproducing temporary stop condition in a certain track on a recording medium by discriminating whether it is possible to execute a combine operation or not by a track connection discriminating device and providing the discrimination result to a user. CONSTITUTION: When a REW-AMS operation is executed during a reproducing temporary stop, a program searching access in the REW direction is first executed and it is put into a temporary stop condition at the access point, i.e., the leading position of a track. Then, the current temporary stop position is defined as a combine point CB and is used to discriminate whether it is possible to combine or not. When it is possible to be combined, a display section 20 displays 'MARK', for example. If it is not possible, no display control is performed. Thus, when it is put into a reproducing temporary stop condition within the track of a recording medium 1, the discriminating device discriminates whether a combine operation can be executed or not. Then, the result of the discrimination is provided to the user and the user confirms whether the operation can be executed or not.

Title: Direct current regulated power supply circuit
Inventor: INABA KATSUHIKO
IPC: G05F1/56
Filed: 1980-05-06
Abstract: PURPOSE:To obtain a power supply device efficient and stable against input voltage fluctuation, by stopping the operation of a starting circuit to perform the regulating control when the output voltage reaches a steady value by the starting circuit. CONSTITUTION:When an input voltage is supplied, a current is supplied from the resistance 20 to the base of a transistor TR19, and the base current of a TR22 is flowed through the collector of a TR19; and if the output voltage at this time reaches a prescribed value, the starting operation of a starting circuit 18 is performed completely. In this case, resistances 25, 26 and 27 are selected to stop the operation of the TR19 of a circuit 18. Therefore, the base potential of the TR19 is restrained to a potential equal to or lower than the potential of the connection point A between resistances 26 and 27. The starting circuit 18 stops the operation to control stably the base voltage of the main control TR22 by the output of a TR23. As a result, DC regulating control efficient against input voltage fluctuation is performed.

Title: Braking device for hoisting device
Inventor: HIRATA MITSUO
IPC: B66C13/23
Filed: 1988-03-16
Abstract: PURPOSE:To make it possible to lower a hung cargo to a safe position by forming the braking device to be released in the case of AC power failure by driving a hydraulic system by means of an emergency battery. CONSTITUTION:When AC power fails, a servolifter 5 cannot support a weight 2 to allow the brake to remain operated. In order to release the brake force, a hydraulic system 6 is driven by the power source of a battery 11 to supply a working fluid to the top side of a hydraulic cylinder 7. The weight 2 is thus lifted through a lever 9, a brake shoe 3 is released from a brake drum 4, and the brake is released to lower a hung cargo. When the hung cargo is to be landed, a solenoid valve of the hydraulic system 6 is switched to supply the working fluid to the rod 8 side of the hydraulic cylinder 7. At this time, the rod 8 is pushed up at very high speeds, thereby the weight 2 is lowered through the lever 9, and the brake force is restored to stop the lowering of the hung cargo. Collision between the hung cargo and the ground can thus be prevented.

Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To reduce operation voltage at the time of recording information in an optical memory card in which information can be recorded by irradiating it with pattern light of two dimensions. SOLUTION: This memory is constituted with multi-layers in each of which a photoconductive film 5 is formed on one side of planes of ferroelectric substance 4 and a transparent electrode 6 is formed on both side and the outermost layer is held by a polarizer 8 and an analyzer. At the time of recording information, pattern light is emitted from the under surface, while a polarizing state of the ferroelectric substance 4 is varied by applying voltage from the transparent electrode 6 varying magnetic fluxes penetrating a coil 3. As each transparent electrode 6 are connected in parallel with the coil 3 being a voltage source, applied voltage to the transparent electrode 6 at the time of recording information can be reduced.
