Title: Commutator motor with eccentric shaft
Inventor: SAKON SHOZO
IPC: H02K23/04
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts and working man-hour for eliminating the unbalance of a rotor by changing the quantity of the winding of the rotor by making partrally uneven the thickness of an insulating member provided between the end face section of a laminated core and the winding, and eliminating the unbalance of the rotor caused by an eccentric shaft. SOLUTION: In a commutator motor with eccentric shaft from which an output shaft 1 eccentrically provided against the axial center of a rotor is protruded outward, the rotor is provided with insulating members 51 and 52 which can easily correct the unbalance of the rotor by partially changing the volume of a winding 4 by providing irregularities in the axial direction on both end faces of an armature core 3. Namely, when the winding 4 is wound on the insulating members 51 and 52, the quantity of the winding 4 wound around thick teeth becomes smaller and that of the winding 4 wound around thin teeth becomes smaller. Therefore, the number of parts and working man- hour for eliminating the unbalance of the rotor are reduced.

Title: Rolling bearing
Inventor: INOUE YOSHIYUKI
IPC: F16C19/00
Filed: 1987-12-22
Abstract: PURPOSE:To provide an increased working life, by a method wherein a steel ball on which a soft metal is coated and a holder made of copper or a copper alloy are used in combination. CONSTITUTION:A steel ball on which silver special ion plating is coated and a holder made of copper or a copper alloy are used in combination. In this constitution, during the initial stage of rotation, silver or copper coated on the steel ball is acted as a solid lubricant. When a given working time passes and the lubricant is in short supply due to friction between the steel ball and a track ring, contact between the steel ball and the holder causes supply of copper or the copper alloy from the holder itself in a way that the copper and the copper alloy is transited to a steel ball surface and a track surface.

Title: Liquid crystal display device and its method
Inventor: SUZUKI YORIHISA
IPC: G09G3/36
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device and its method in which the display color level of a vertical non-image part (mask area) is never fluctuated by bright regulation. SOLUTION: When the display size of image based on a video signal is differed from the screen size of a liquid crystal display panel 15 in a liquid crystal television 1, an LCD controller 12 (switching control means) switches analog switches S1, S1 (switching means) in a period for supplying a display signal to each picture element electrode of vertical non-image parts 15a, 15c (mask area), so that the amplitude in a VCOM signal generating part 13 (common signal amplifying means) becomes a high magnification. Thus, the liquid crystals of the vertical non-image parts 15a, 15c are alternately driven by the display signal supplied to each picture element electrode and a VCOM signal amplified at a high amplification ratio which is supplied to a common electrode.  Thus, even if the brightness of an image is regulated by bright regulation, the black level of the vertical non-image parts 15a, 15c (mask area) is never fluctuated.

Abstract: PURPOSE:To enhance the efficiency of defruiting processing by eliminating a shift register and reducing a circuit scale by performing defruiting processing for removing the fruits contained in a secondary monitor radar video after the detection of a bracket. CONSTITUTION:Defruiting processing 9 is realized by firmware and provided in front of target detection processing 10 within a microcomputer 8. Since a report is inputted to the microcomputer 8 through a bracket circuit 4, said report is inputted in the order of a small detection range. Therefore, the range of the report of the previous sweep is compared with that of the report of the present sweep in input order in the processing 9 composed of firmware and, when the coincidence of the ranges is taken, the report is judged to be based on a real target and, when said coincidence is not taken, fruits are judged. By this method, defruiting function can be realized.

Title: Connector
Inventor: TSUJI KENJI
IPC: H01R13/52
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To prevent water from intruding at a high pressure into a cover from the drain hole provided in the cover for water-proofing. SOLUTION: A cover 35 consists of a pair of semi-cylindrical pieces 36L and 36R coupled together by a hinge 37 (shutter means). A drain hole 47 is formed in the undersurface of the cover 35, and the hinge 37 is installed in such a way as hindering viewing straight the inside and outside of the cover 35 through the drain hole 47. When water is splashed straight with a high pressure over the hole 47 from outside the cover 35, the water runs against the hinge 37 and does not reach the hole 47 directly. With eventual water intrusion, it is splashed back to the inner surface of the hinge 37 and the water energy is weakened, so that there is not risk that high pressure water intrudes to the inside of the cover 35.

Abstract: PURPOSE:To perform surgery on a valve leaf with a scalpel or a sharp spoon completely and correctly by forming a support apparatus with holding section for an operator, an arm section inserted with an optical fiber, and a tip section bent into a hook shape. CONSTITUTION:A casing 4 has a light source 5, a battery 6 and an on/off switch 7 for the light source 5 in it. An arm 8 is bent into a hook shape at the tip, and an optical fiber 9 is inserted into it. The light sent from a radiation port 11 penetrates a valve leaf and reaches the eyes of an operator to tell the calcified portion, the thickness of the valve leaf, and the position of the radiation port 11 to the operator, and the arm 8 is closely stuck to the valve leaf from below and can support the valve leaf. The calcified portion is displayed as a dark image by the transmission light, the other portion is displayed as a bright image, thus the calcified portion, particularly the calcified portion deposited in the valve leaf invisible from the outside, can be searched. The light source 5 of the transmission light is brightest at the center section, thus the position supporting the valve leaf is correctly shown to the operator even if it is located below the valve leaf invisible to the operator.
