Title: Protecting apparatus for electric motor vehicle
Inventor: KOUNO TOSHIKATSU
IPC: B60L3/00
Filed: 1982-04-14
Abstract: PURPOSE:To prevent a DC circuit including a main motor from becoming an overcurrent state by reducing the output of a field power source when an electric motor vehicle passes an AC-AC section during a regenerating operation. CONSTITUTION:A main circuit voltage controller 9 and a field voltage controller 23 input a command signal from a master controller 8 and respectively control a thyristor power source 5 and a field thyristor power source 21. When a vehicle element 11 detects a signal from a ground element 12 installed before an AC-AC section SE while an electric motor vehicle carries out a regenerating operation, the controller 9 controls the phase shift to the degree not fail the commutation of the thyristor of the power source 5, and the controller 23 cuts the output of the power source 21, thereby setting the field current to zero. When a vehicle element 11 detects a signal from a ground element 26 installed at the rear of the section SE, the regenerating operations again carried out.

Filed: 1979-05-21
Abstract: PURPOSE:To shorten the time of work greatly by grasping a trimming position with accuracy by detecting the variation start position of the oscillation frequency of a crystal vibrator when the oscillation frequency of the crystal vibrator is adjusted by irradiating the crystal vibrator with a laser beam. CONSTITUTION:Crystal vibrator 1 is placed at a work position and the initial irradiation position of a laser beam is set at point 11. Next, the laser beam is made to scan from point 11 to point 12 linearly and when there is no variation in oscillation frequency between both the points, the scan is advanced from point 12 to point 13. Thus, when a change in frequency is obtained at point 20, the Y coordinate of point 20, namely, that of coarse-adjusting thin film 2 is stored and at the same time, the start Y coordinate of fine-adjusting thin film 3 is calculated by CPU in terms of only DELTAY. Next, the scan is taken from point 22 to point 31, and consequently coordinates of thin films 2 and 3 can be found. As a result, the time of work can remarkably be shortened by finding a trimming position with accuracy.

Title: Manufacture of decorative sheet
IPC: B32B27/10
Filed: 1992-03-18
Abstract: PURPOSE:To improve taste and aptitude for fabrication by a method wherein a printing pattern layer and a primer layer are successively laminated on mixingly manufactured paper and after applying polyvinyl chloride resin on the surface, it is made to get by heating and a surface on the printing pattern layer side is embossed. CONSTITUTION:At first, a printing pattern layer and a primer layer are successively laminated on an upper surface of mixingly manufactured paper.

Thereafter, the polyvinyl chloride is made to gel by heating and a surface on the printing pattern layer sidle is embossed. A sheet composed of paper and the vinyl chloride resin can be processed thereby on the surface of the sheet with embossing which is abundant in taste because of a large vertical difference between a projection and a recess. Further, good aptitude for fabrication wherein troubles such as crack or the like are difficult to occur can be added even to an angular state base material which is difficult to be laminated.

Abstract: PURPOSE:To obtain a bi-directional circuit operating means which hardly acquires a circuit double and uses circuits uniformly by shifting the selection order of the acquisition of a free circuit between both exchanges by >=1 from each other. CONSTITUTION:When an exchange A(1a) uses the circuit with a circuit number 3, both exchanges A(1a) and B(1b) give new idle order numbers (1), (2), and (3) to circuits with circuit numbers (1), (5), and (6); and those circuits are given selection order numbers (1), (2), and (3) by the exchange A(1a) and selection order numbers (3), (1), and (2) by the exchange B(1b). As another example, when the circuit having a circuit number (2) becomes free, the circuits having circuit numbers (3), (1), (5), (6), and (2) are given idle order numbers (1), (2), (3), (4), and (5) newly by both exchanges A(1a) and B(1b), and those circuits are further given selection order numbers (1), (2), (3), (4), and (5) by the exchange A(1a) and selection order numbers (5), (1), (2), (3), and (4) by the exchange B(1b). Therefore, double acquisition never occurs unless the number of calls exceeds the total number N of circuits in a group 5.
