IPC: H02K15/03
Filed: 1986-06-16
Abstract: PURPOSE:To constitute a large-diameter polygonal mirror surface which realizes high resolution into the integral structure which is thin and flat and to form a titled scanner so as to withstand high-speed rotation by forming respectively different anisotropic structures into the inside and outside peripheral part of a magnet rotor consisting of a carbon alloy by a specific simple process. CONSTITUTION:The desired outside peripheral part of the rotor 7 consisting of a manganese-aluminum-carbon alloy magnet is formed as the part 7b where the axis of easy magnetization is preferentially oriented within the plane perpendicular to the rotation axis direction of the rotor 7. The desired face of the outside peripheral part is formed to a specular surface 7c. The greater part of the outside peripheral part of the rotor 7 where the rotor faces an electromagnetic coil 8 is so formed that the axis of easy magnetization is preferentially oriented at least in the direction parallel with the rotation axis direction of the magnet rotor. The magnet rotor and the polygonal mirror are thereby made into the integral structure which is thin and flat. The optical scanner which has the large diameter of the polygonal mirror and has the high motor efficiency and has the structure to withstand the high speed rotation is thus obtd.

Title: Sheet manuscript automatic handling device
Inventor: YOSHIMURA SHIGERU
IPC: G03G15/00
Filed: 1979-10-29
Abstract: PURPOSE: To prevent picture distortion with a low cost, by providing an original stop pawl which positions the original in its feed direction at the original coming to the original exposure part and is released immediately after stop of the original carrying belt.  
     CONSTITUTION: In case of handling of thin originals, when the original is stopped by original stop pawl 18, the original is distorted in the contact part of original stop pawl 18, and picture distortion is generated. Then, original stop pawl 18 is so constituted that it may be placed to stop the original but may be released upward immediately after stop of rotation of carrying belt 10 simultaneous with stop of the original. Consequently, even if the original is distorted temporarily by original stop pawl 18 at the stop of the thin sheet original, the original is stretched forward to prevent picture distortion by releasing pawl 18 upward. Thus, picture distortion can be prevented with a low cost.

Title: Protective circuit with ptc device
Inventor: RII MAAKU MIDORUMAN
IPC: H01C7/02
Filed: 1995-06-06
Abstract: PURPOSE: To handle a relatively high current by cutting off a specific PTC element, when a current flowing to the specific PTC element increases and the temperature of the PTC element rises, and suppressing the flowing current and protecting a circuit. CONSTITUTION: A PTC(positive temperature coefficient) element 1 is formed of a PTC conductive polymer. The PTC conductive polymer has a resistance value of <=5 Ω.cm at 25 deg.C, and the crystal fusion point of the polymer is at least 180 deg.C. A protecting circuit 11 (resistance value <1 Ω and <0.5 RLΩ) has metal flat plate electrodes 2 which are arranged on both sides of a constant thickness (t) and is brought into direct contact with the PTC element 1, and a current flows within a range of d/t>=10, where (d) is an equivalent diameter within a range of the current flowing to the PTC element 1. When a current flows from a power source to a circuit element through a circuit protector 11, the PTC element 1 is heated with the circuit current.  Thus when the temperature of the PTC element 1 rises, the PTC element 1 is cut off to suppress the current circuit, thus protecting the circuit.

Title: Electric wire drum for feeling prefabricated electric wire string for completely prefabricated wire stringing and method for reeling electric wire on the electric wire drum
Inventor: YOKOYAMA KAZUO
IPC: H02G1/06
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To inexpensively and easily increase the number of divisions of an existing electric wire drum and apply an electric wire drum divided into two or three or so for large-scale transmission lines to small-scale transmission lines, in such a manner that even an unoccupied portion of the electric wire drum is minimized. SOLUTION: A first electric wire 1a is wound regular over a first block. A plurality of partitioning members 33 for multilayer winding are placed on the first regularly wound layer of the first electric wire 1a in the circumferential direction. The portion close to a split wire 2a, including a compressive anchor clamp 4a' at the trailing end of the first electric wire 1a and a compressive anchor clamp 4b at the leading end of the second electric wire 1b is reeled inside the partitioning members 33 for multilayer winding. The second electric wire 1b is wound over the regularly wound layer of the first electric wire 1a outside the partitioning members 33 for multilayer winding. Thus two layers can be wound in one block on the electric wire drum, and additional threads can be further wound on an existing electric wire drum.  Owing to the partitioning members 33 for multilayer winding, the number of divisions of the existing electric wire drum can be readily substantially increased at a low cost.

Title: Wafer holder and manufacture of semiconductor wafer
Inventor: HUBER ANTON
IPC: B24B7/22
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To enable grinding and rounding the edge part even if stains of a semiconductor wafer are so roughly removed that the surface is still stained to be visible by forming a support for fixing a semiconductor wafer during grinding of a soft material. SOLUTION: In case of grinding a first surface, a semiconductor wafer 1 is fixed on a wafer holder having a soft support 6. Both surfaces of the semiconductor wafer 1 obtained by cutting a crystal are not flat surfaces, and not parallel to each other. After washing the wafer, particles remaining between the semiconductor wafer 1 and the support 6 will not deform the semiconductor wafer 1, but the particles are forced into the soft support 6 when the wafer is fixed to the wafer holder 3. Similarly also during grinding the front surface 2, a non-uniform area of the back 5 of the semiconductor wafer 1 is received by the support 6. Thus, grinding and rounding the edge can be performed without special labor.

Title: Method for operating vacuum degassing furnace for molten steel
Inventor: OKAMOTO MASAHARU
IPC: C21C7/10
Filed: 1985-06-25
Abstract: PURPOSE:To prolong the life of a refractory contg. carbon as the lining of a vacuum vessel by adding a slag forming material to molten steel in the vessel during degassing so as to inhibit the oxidation of the refractory. CONSTITUTION:A vacuum vessel is lined with a refractory contg. carbon and a slag forming material is added to molten steel in the vessel during degassing. Slag scatters and sticks to the inner surface of the refractory. When the evacuated state of the vessel is returned to the original state after degassing, the slag line lowers together with the surface of the molten steel in the vessel and slag sticks successively to the part covered with the molten steel during degassing. The rear side of the refractory is temporarily under reduced pressure while the inside of the vessel is under atmospheric pressure when the evacuated state of the vessel is returned to original state, so the slag sticking to the refractory is sucked into the refractory. The slag penetrates into the structure and joints of the refractory and more surely inhibits the oxidation of the refractory.

Abstract: PURPOSE:To achieve a high density of electrical current, by previously subjecting a high-molecular electrode to doping and anti-doping with ions of large radium in a different electrolyte solution. CONSTITUTION:A battery comprises a positive electrode 1, a negative electrode 2 and an electrolyte 3.
