Title: Horizontal deflection circuit
Inventor: MOTAI KENJI
IPC: H04N3/16
Filed: 1989-04-26
Abstract: PURPOSE:To apply the circuit to a high frequency high quality television receiver or a display device by employing a gate bipolar transistor(TR) with an excellent frequency characteristic for a device for switching in a horizontal deflection circuit and compensating the defective ON-characteristic while giving a current to a circulation circuit in advance provided between the collector and the emitter of the TR. CONSTITUTION:An insulation gate TR 61 is used for a switching device 6 of a horizontal deflection circuit and a circulation circuit 7 is provided between the collector and the emitter of the TR 61, and the circulation circuit 7 consists of a power supply 71, a resistor 72 and a reverse flow prevention diode 73. A minute circulation current flows to the TR 61 of the device 6 while a damper diode 4 is turned on for a consecutive operating period with a control signal S from the control section 6a. When the consecutive operation of the diode 4 is finished, the TR 61 rises from the minute conductive state to the state of the circuit current of the main circuit at the rising of the current of the main circuit. Then the defect of the ON-characteristic of the TR 61 is compensated.

Title: Installation method of cover for grooved wiring floor
Inventor: YAMAMOTO KIYOSHI
IPC: E04F15/024
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To form costlessly and stably the whole floor face to be nearly flat by projecting a part of a rigid thin plate constituting side faces of a floor plate at a specified position of the side faces of the floor plate made of a rigid thin plate laid on the floor face at every specified distance to form fixing projections and fixing a groove cover inserted in the wiring groove to the fixing projections. SOLUTION: The four peripheral sides of a square surface plate 10 are bent downward at right angles to form support legs 2, in a floor plate 1 formed by using a rigid thin steel plate such as a galvanized steel plate. The lower ends are shortly bent at right angles to form grounding pieces 21. Further, the side face of the support legs is partly notched and the part is bent upward to form a fixing projection 3. The floor plates 1 are laid on a floor face to put a wiring groove 4 with a specified width between them. The groove cover 6 is laid between the fixing projections 3 of the floor plates 1 of both sides to flatly finish the whole surface and form the grooved wiring. The fixing projections 3 can be formed at the time of press-molding of the floor plate 1 and since other members are not required nor fitting labor is required, materials and processing are costless.

Abstract: PURPOSE: To obtain a tool for stripping a sheath from the continuous layer of a coaxial cable in order to fix a terminal in which a required processing work is realized without requiring any skill by combining a cable and a terminal specifically and replacing a set of tool easily for another cable and/or terminal. CONSTITUTION: When a cable guide 40 suitable for the diameter of a cable is fitted to a tool and a component 26 is closed after inserting a cable, a pawl 32 engages a ratchet 20 and cutters 34, 36, 38 bite the cable. When the tool is turned, the cutters 34, 36, 38 further bite the cable while cutting the cable coating in the circumferential direction. Biting is eventually blocked when the end face 64 is located on the surface 66 of the body. The tool is turned by one more revolution under that state and the cable is drawn out from the tool thus removing the coating. A set of tools can be replaced to fit the cable and the terminal and can be adjusted finely by means of an adjusting screw 68.

Abstract: PURPOSE:To make the illuminance distribution uniform and construct in a small size by bending a prop, corresponding to inter-electrode span of a light emitting tube, toward the tube, and thereby decreasing influence of the shade of the prop on the irradiated surface without impairing the mechanical strength of the prop. CONSTITUTION:A prop 1 is provided with a bend 1a in the part corresponding to the inter-electrode (31a, 31b) span, wherein the bend 1a starts at the upper and lower bent points 1x of the prop 1 extending toward the center of the light emitting tube concerned 30. In the part formed by bending, the distance between the tube 30 and prop 1 is not constant to cause the prop 1 not to be parallel with the tube 30, so that the shadow of the prop 1 produced by the light from the tube 30 will not be constant to cause unfocused and weak contour. This accomplishes uniform distribution of illuminance and small-sized construction without impairing the mechanical strength of the prop 1 supporting the light emitting tube 30.
