IPC: H01B13/00
Filed: 1993-11-26
Abstract: PURPOSE:To prevent the generation of the mechanical disarrangement of a superconductive wire at the time of generation of a high magnetic field by a method wherein the superconductive wire, which forms a superconducting coil, is solidified and fixed by glassy ceramic. CONSTITUTION:Borosilicate glass powder is mixed in the mixed powder of alumina powder and forsterite powder and the mixed powder is made to disperse in an alcohol to form a ceramic powder slip 5. Then, the ceramic powder slip 5 is coated on a superconductive wire 4 and while the slip 5 is dried, a winding is executed and after the winding of an internal coil 3 ends, the slip 5 is coated on the outer peripheral surface of the coil 3 and moreover, a drying treatment is performed. Then, a heat treatment is performed in a vacuum using an A-15 phase formation treatment using a wind and react method and a ceramic sintering treatment in combination as one treatment to manufacture a superconducting coil 1. Thereby, a fixing of the wire material 4 is strengthened and it becomes possible to obtain the superconducting coil which generates stably a high magnetic field.

Title: Cooling method inside duct way
Inventor: ISHII FUJIO
IPC: H02G9/00
Filed: 1989-12-11
Abstract: PURPOSE:To ventilate and cool the inside of a duct way securely by providing water cooling devices on the intake side of the duct way, taking outside air into these water cooling devices by blowers to cool, and guiding the air into the duct way. CONSTITUTION:When blowers 6 operate, outside air is taken into water cooling towers 13 by their suction force through the medium or nets 18. Meanwhile, water absorbing belts 14 move round as motors 17 drive belt wheels 15. Accordingly, the outside air touches the water absorbing belts 14 in the water cooling towers 13, and is cooled as its heat is taken away. The cooled outside air is made to pass thorugh ducts 12 and ventilating ducts 5 by the suction force of the blowers 6, and guided to the inside of a cut way 1 through intakes 3. Accordingly, the cooled outside air flows through the inside of the duct way 1 cooling and ventilating the inside, and is exhausted from exhaust holes 4. This makes it possible to prevent the transmission capacity of a power cable 2 from lowering by keeping the inside of the duct way 1 at a low temperature, and facilitate maintenance and inspection.

Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To obtain the magnetic head having excellent inductive noise resistance without generating corss talk and capable of preventing misrecording/ misreproducing due to interference of an erasing head. SOLUTION: Magnetic heads 2 and 3 for an FDD, etc., are constituted, and a 1st coil 17 and a 2nd coil 19 for generating recording magnetic flux respectively in the different directions from each other are disposed independently of each other, and coupling capacity of these coils 17 and 19 is reduced, so as to raise a resonance frequency which depends upon this coupling capacity and inductance of the coils 17 and 19. By this method, noise from an inductive noise source and crosstalk from the heads 2, 3, etc., on the sides opposite to each other are suppressed.  Then, the 1st coil 17 and the 2nd coil 19 are made to be different from each other in the number of turns, so as to compensate a generated magnetic field and/or asymmetry of magnetic recording cause by interference of leakage magnetic flux of the easing head 3, thus reducing the occurrence of errors such as misrecording and misreproducing, etc.

Abstract: PURPOSE:To make emitted light intensity uniform in accordance with an electric current to each LED by providing an LED array obtained by series connecting of LEDs, switching elements respectively connected in parallel to the LEDs and a constant current device supplying an electric power to the LED array. CONSTITUTION:Phototransistors T1, T2,...Tn are turned ON if they make a pair with light emitting diodes E1, E2, ... En connected to output terminals of an LED driver 1 turned to L level. On the contrary, phototransistors T1, T2, ... Tn remain in OFF states if they make a pair with light emitting diodes E1, E2, ... En connected to H-level output terminals of the driver 1. In the phototransistor turned ON, an area between an emitter and a collector is clamped by a saturation voltage. However, because a forward voltage of the LED connected to the ON phototransistor in a parallel system is higher than the saturated voltage, all the currect flows to the phototransistor and does not flow to the LED. On the other hand, the current flows to the LED connected to the OFF phototransistor in a parallel system. An electric current passing through LEDs L1, L2,...Ln or the transistors T1, T2,...Tn in this manner is a constant current (is) supplied from a constant current device 2.

Filed: 1993-12-22
Abstract: PURPOSE:To assure the stable light controllable effect of an automatic light controllable device over a long period of time while making the light quantity distribution of lens transmitted light without shielding this light by shielding members. CONSTITUTION:A lens plate 3 having plural pieces of cylindrical lenses 5 is supported via thermally expandable supporting members 4 by a transparent plate 2. The shielding members 6 are arranged within the optical path of the lens transmitted light where the optical path section is smaller than the optical path section of the incident light on the cylindrical lenses 5.
