Title: Double-layered semiconductor capacitor
Inventor: MATSUMOTO TETSUYA
IPC: H01L27/04
Filed: 1991-11-29
Abstract: PURPOSE:To eliminate the parasitic capacitance between a wiring material and a lower electrode by providing cut-offs for the lower electrode so as not to allow the lower electrode to exist under the wiring material connected to the upper electrode. CONSTITUTION:No lower electrode 13 exists immediately below the wiring material 10 made of Al connected to an upper electrode 12 through a contact 11. Here, the parasitic capacitance is almost zero. Thus, no parasitic capacitance exists between the wiring material 10 of the upper electrode 12 and the lower electrode 13, making it possible to design a capacitor block of a high precision ratio in a switching capacitor circuit, A/D converter, D/A converter, or some other circuits in which the precision ratio of capacitance may present a problem.

Title: Manufacture of woody tape and woody tape
Inventor: TSUDA EIJI
IPC: B27D5/00
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a woody tape which is produced by joining a continuous backing sheet to the rear surface of a continuous veneer prepared by connecting a plurality of ultra thin veneers in one row, in which the poor joining due to the uneven coating of an adhesive is dissolved and, in addition, which is excellent in cost reduction and production efficiency. SOLUTION: By running a continuous backing sheet 4 formed in a uniform thickness under tension and the continuously coating an adhesive through a roll coater 7 or a hotmelt applicator on the top surface of the backing sheet, uneven coating is prevented from developing, resulting in improving the joining strength between the continuous backing sheet 4 and a continuous veneer 3. Further, since no uneven coating develops, a small amount of adhesive is enough for coating, resulting in saving the adhesive and reducing the production cost of a woody tape.

IPC: B25J3/00
Filed: 1992-10-30
Abstract: PURPOSE:To perform continuance of a work even when an overload is detected by a method wherein when contact of a robot with a rigid body is detected, the limit value of a torque limiter is reduced to a value lower than a rated value, a speed command is prevented from an output, and after confirmation of the stop of a robot, a position command is caused to coincide with feedback, and a torque limiter limit value is restored to a rated value.

Title: Initial water pouring apparatus of hot water heating system
Inventor: HAMADA KAZUTAKA
IPC: F24D3/10
Filed: 1989-12-05
Abstract: PURPOSE:To automatically perform an initial water pouring operation of a hot water heating system by providing time measuring means for measuring a resupplying interval of hot water and initial water pouring completion determining means for stopping the initial water pouring operation when the resupplying interval of hot water exceeds a predetermined time. CONSTITUTION:When a pump 3 is driven, resupplied not water is resupplied into a piping 4 and a radiator 5. Therefore, hot water in a heating source unit 1 decreases, so that decrease of the hot water therein is detected by a water level detector 6. When the hot water is continued to be resupplied into the piping 4 and the radiator 5, an interval from closing a solenoid valve 7 to the detection of decrease of the hot water by the water level detector 6 becomes long. The resupplying interval of the hot water is measured by time measuring means, thereby making it possible to determine completion of an initial water pouring operation, namely, whether the resupplying interval of the hot water is longer than predetermined time or not. When the completion of the initial water pouring operation is determined by initial water pouring completion determining means 10, a signal outputted therefrom is inputted to control means 8. Then, the pump 3 is stopped by the control means 8, thereby finishing the initial water pouring operation.
