Title: Wiring duct device for desk with socket attachment part
Inventor: YOSHIDA RYUJI
IPC: A47B13/00
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To easily insert and detach a plug to/from a socket, to prevent the socket and the plug inserted to it from becoming the obstruction of left and right direction wiring inside a wiring duct and to neatly wire cord kinds.

Title: Measuring instrument for quantity of abrasion of furnace wall
Inventor: OZAKI YUKIO
IPC: G01C3/06
Filed: 1986-06-05
Abstract: PURPOSE:To improve the measurement accuracy of the quantity of wear of a furnace wall by measuring the same point on the wall surface in a furnace which is not used by two sensors and storing their data, and comparing them with data obtained by measuring the same point on the internal wall surface in the furnace after operation. CONSTITUTION:The wall surface in the furnace after refractory lining is measured by the sensors 40 and 41, whose data are compared by an image processor 43. A controller 44 when judging that the same point is not measured from the comparison result controls a driving device 45 to adjust the angles of the sensors 40 and 41. Then, the angles of both sensors to the same point are measured and stored in an image memory 42. Then, the angles of both sensors to the same point on the wall surface in the furnace after certain-period operation are measured and processed along with the stored data to calculate the quantity of wear of the furnace wall. Consequently, the measurement accuracy of the quantity of wear of the furnace wall or remaining thickness is improved.

Title: Supply controller for pinball
Inventor: IKEDA HIROSHI
IPC: A63F7/02
Filed: 1989-05-24
Abstract: PURPOSE:To make a supply controller for pinball compact by providing a shutter, to which balls can freely go in and out, in a driving device out of a falling route in a part out of the center of a cross surface in the falling route for pinball equipped with side walls. CONSTITUTION:In the part out of a center 5 of the cross surface in a falling route 2 for pinball equipped with side walls 1, a shutter 3 is provided in a driving device 4, which is provided out of the falling route 2, so that the balls can freely go in and out of the shutter 3. Accordingly, when the shutter 3 is protruded into the falling route 2, the shutter 3 is inserted between upper and lower balls 10 under falling and component force directing the outside of the falling route 2 is received by the lower spherical surface of the ball 10 in the upper direction of the shutter 3. However, since the direction of the component force is not same as the axial direction of the shutter 3 but crossed with the axial direction, the component force to push back the shutter 3 is widely decreased. Thus, necessity for the driving device to prevent the shutter from being pushed back is eliminated and the supply controller is made compact and low-priced.

IPC: H04N5/378
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a power circuit for CCD camera which can improve the starting characteristic of a flyback circuit. SOLUTION: When a power switch 20 is turned on, a power-on signal is outputted from a microcomputer 18, and a chopper circuit 24 is started by a switching controller 22.

Abstract: PROBLEM TO BE SOLVED: To readily obtain high interfacial bonding strength, high rigidity, good slidability, chemical resistance, fatigue resistance or the like by avoiding a skin layer on a surface of a primary molding in the contact surface of the primary and secondary moldings. SOLUTION: A crystalline resin material A is pre-molded to form a primary molding, to which a thermoplastic resin material B is secondarily injection- molded and fused therewith, so as to integrate both of them. The joining surface of the primary-side resin material is subjected to a flame treatment or a hot air treatment, and a portion or all of the surface layer of the joining surface is melt-treated, e.g. by being re-melted, gradually cooled and solidified, thereby substantially avoiding the skin layer of the surface. The flame treatment or hot air treatment is readily applied to only the joining surface of the primary molding, e.g. by applying the hot air at a high temperature to a cavity after the primary molding is provided in the secondary mold which is then closed. The molding method is most preferably an injection molding.
