Title: Manufacture of blanking die for pattern
Inventor: KASAI YASUO
IPC: B26F1/00
Filed: 1979-12-20
Abstract: PURPOSE: To manufacture blanking dies for pattern in a short time and at a low cost, by performing main etching with photoresist coating formed on a substrate, then by forming edge by finish etching after the removal of the photoresist coating.  
     CONSTITUTION: Photoresist coating 3' of uniform line breadth W is formed nearly along the central line of pattern to be blanked on a steel substrate 2. The substrate 2 is attacked with etching soln. 4, and the etching of the side is continued until very fine edge reduced in width remains at the central part of the photoresist coating 3'. Then the edge 5 of width (x) is exposed by peeling the coating 3'. Etching soln. is then poured onto the exposed edge 5 in order to perform finish etching to form edge 6, and the finish etching is continued to complete sharp edge 7. This method allows to form a ridge line of edge at the center of linear pattern, hence product of high dimension accuracy is obtained.

Title: Voltage control method for power system
Inventor: MOTOHASHI JUN
IPC: H02J3/12
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To control a load center point voltage of the power system to constant value through cooperative control of a step voltage controller (SVR), using a tape transformer and a serial voltage controller(SVC) consisting of a serial transformer and a power converter. SOLUTION: SVR switches the tap of a transformer so as to make a load center point voltage almost constant. A serial SVC calculates a load center point voltage VL with a secondary voltage V2 of SVR, a current I, line constants R, X and controls reactive power or active power output from SVC to output a compensation voltage Vc, in the same phase as V2 for making equal VL to load center point reference voltage Vref. However, SVR switches the tap, so that VL becomes almost equal to Vref for voltage change due to gradual change of load and a serial SVC compensates for compensation amount Vc for sudden change of the voltage, which cannot be compensated by SVR.
