Title: Roller for belt conveyor
Inventor: NAKAMURA KAZUHIRO
IPC: B65G39/071
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a roller for a belt conveyor of a simple structure in which a conveyor belt is not deflected even when tension change by a load position (loading position) of a load such as a luggage, deflecting tendency of the belt conveyor, etc., occur. SOLUTION: As friction force to a conveyor roller of a conveyor belt B is increased because of tension change by a load position (loading position) of a load such as a luggage, deflecting tendency of the belt conveyor B, etc., at a part where these occur, one half part of a parted body (a) including the part is inclined in a friction force reducing direction, that is a direction to get closer to a support shaft 1, while the other half part is inclined in a friction force increasing direction, that is a direction to get apart from the support shaft 1 to increase the friction force. Respective parts of the conveyor belt B thus get in contact with a roller surface A' with roughly uniform friction force, thereby the conveyor belt B is naturally guided to be perpendicularly guided to be rotated or driven by the belt conveyor rollers A.

IPC: E05B1/00
Filed: 1994-08-30
Abstract: PURPOSE: To prevent the backlash of the lock knob of a door handle for an automobile without increasing parts in number. CONSTITUTION: A shaft 2 is disposed in through holes 11a and 12a bored in a first support wall 11 and a second support wall 12 which are provided in parallel with a base 1.

Title: Power steering device
Inventor: KOMAMURA SEIJI
IPC: B62D5/22
Filed: 1985-09-17
Abstract: PURPOSE:To make a device compact through electrically connecting a detection part to a motor so as to free the positional relation between both, by electrically detecting input from a handle and putting a motor, provided on the output side, in follow-up rotation corresponding to said detection. CONSTITUTION:When a handle 1 is operated in any direction, due to grounding resistance of a wheel 45, the rack 43 of a side rod 42 engaged with the pinion 40 of an input shaft 2 does not move instantly, and torsion is produced on the input shaft 2. Then the angle of torsion is electrically detected by means of the strain gauge of a detection part 3, and a motor 25 is driven by a control circuit 8 correspondingly to the angle of torsion and the direction of torsion. Thereupon, the pinion 44 of the motor 25 starts its rotation in the same direction as that of the pinion 40 of the input shaft 2 to put the rack 43 in movement and the side rod 42 in stroke, therefore, the wheel 45 is changed in its direction. Due to this structure, which does not impose restrictions on relative positions of the detection part 3 and the motor 25, an expected purpose can be attained.

Abstract: PURPOSE:To discriminate propriety of a semiconductor device visually or with optical means without inking agent. CONSTITUTION:An operation checking circuit 3A of a semiconductor integrated circuit (IC) 4 is provided at input/output terminals of each one unit of the IC 4. An operating voltage and a test signal of the original IC 4 are respectively applied to a power terminal 5 and input/output terminal 7a of the circuit 3A.

Abstract: PURPOSE:To enhance a yield by a method wherein, after a semiconductor water has been coated with a silicon compound solution, a silicon compound solution film in a peripheral part of the semiconductor wafer is removed before the wafer is heat- treated in order to prevent a silica component from being released as a particle. CONSTITUTION:After a semiconductor wafer 1 has been fixed to a rotary chuck 3, a silicon compound solution is dropped to the central part of the semiconductor wafer 1. Then, while the rotary chuck 3 is being turned, the silicon compound solution is spread uniformly over a wafer face by means of a centrifugal force. During this process, an excess silicon compound solution is blown off to the outside of the semiconductor wafer 1; however, a silicon compound solution film 2 is formed in a peripheral part and an end part of the semiconductor wafer 1. Then, a removal liquid of the silicon compound solution film is applied, from nozzled 4A, 4B, to the peripheral part of the semiconductor wafer 1 which is being turned; the silicon compound solution film in the peripheral part and the end part is removed. An acid containing hydrofluoric acid or an alcohol is appropriate as the removal liquid. While the water is erected in a wafer support jig 5 and heat-treated in an atmosphere of O2 or H2O, a solvent other than a silica component is evaporated.

Title: Optical head device
Inventor: SHIKAMA SHINSUKE
IPC: G02B6/12
Filed: 1984-10-01
Abstract: PURPOSE:To reduce the number of moving elements to make a device small in size and high in reliability by forming an optical head system on a thin film waveguide and forming a minute oscillating spot to a disc with an electric means using the elastic optical effect. CONSTITUTION:A collimator lens 5, a beam splitter 10, a grating coupler 11, and a comb-shaped electrode 7 are formed on a thin film optical waveguide on a substrate 1 having the elastic optical effect. When a high frequency from a frequency sweep oscillator 62 is applied to the electrode 7, a surface acoustic wave 8 is generated in the thin film. Consequently, the luminous flux from a semiconductor laser chip 3 is deflected oscillatorily by the surface acoustic wave 8 to form the condensed light spot, which is oscillated minutely, on the surface of a disc 15. Tracking of information tracks and reading of information signals are performed similarly to a conventional device by this spot. Thus, the number of moving elements is reduced to obtain a small-sized and high- reliability head device.

Title: Manufacture of shadow mask frame

IPC: H01J9/14
Filed: 1987-08-21
Abstract: PURPOSE:To improve reliability of a shadow mask with a uniform tension and less wrinkles by placing the shadow mask on a frame, pressing the shadow mask with another frame to make the shadow mask adhere to the frame, and welding the portions of the shadow mask inside or outside the other frame. CONSTITUTION:A frame 1, placed on a table 4 made of a material of good conductivity connected to one of electrodes 3 of a welding power source, is electrically connected to the electrode 3. A shadow mask 2 is flatly held with its several positions stretched in radial directions from the center by means of springs 6 attached to a holding jig 5. Upon moving and fixing the frame 1 to a specified position, a frame 8 is lowered to be pressed in close contact the shadow mask 2. The thermally expanded shadow mask 2 is pressed and brought into close contact with the frame 1 by means of the frame 8 and welding positions of both of the components are fixed. Another electrode 9 for seam welding is rotated while in contact with the frame 8 to perform the seam welding. Since the thermal capacity of the frame 1 is large, temperature rise due to the welding is small. On the other hand, since the shadow mask 2 is fixed to the frame 1 while being heated and expanded, tensile forces are produced on the entire surface when cooled to the room temperature.

Abstract: PURPOSE:To obtain a large converting gain with low distortion and a small local oscillation input by constituting a double balanced mixer circuit by dual gate FETs of common source. CONSTITUTION:The second higher harmonic distortion of the double balanced mixer circuit is suppressed by inverting the phase of an output at an intermediate frequency output terminal 19 out of two output terminals 18, 19 of the circuit further and synthesizing the result with an output of the terminal 18.
