Inventor: MURAI MASAO
IPC: B23H1/02
Filed: 1995-05-10
Abstract: PURPOSE: To completely prevent the deterioration of a machined surface in accordance with the degree of the electrocorrosion of an article to be machined, by detecting mean voltage between electrodes to switch the polarity of voltage, for inducing electric discharge, between electrodes so that the mean voltage can conform to a reference value. CONSTITUTION: A control circuit inputs bath voltage between a machining electrode 1 and an article 2 to be worked to detect electric discharge, and also outputs a control signal to a main electric discharge circuit 3 and to an electric discharge inducing circuit 4 based on an electric discharge detection signal. A switching circuit (including a differential amplifier 57, a comparator 55, a latch circuit 54, and AND gates 51 and 52), is a circuit for receiving the bath voltage and a control signal from the control circuit to control the opening/closing of the switch elements (44 and 45) and (46 and 47) of the circuit 4.  The applied polarity of electric discharge inducing voltage to between electrodes is switched, the mean voltage of the electric discharge inducing voltage between the electrodes is made a reference value, and effect due to electrolytic action generated by applying electric discharge inducing voltage is substantially eliminated, thereby preventing the deterioration of the surface of an article to be machined.

Title: Dielectric filter
Inventor: SUZUKI SHIGEMI
IPC: H01P1/205
Filed: 1981-08-28
Abstract: PURPOSE:To attain small size and light weight, to reduce adjusting components, to decrease number of components and to improve productivity, by inserting a head of a screw rod for the adjustment of degree of coupling to a spot-facing part formed on a cover and eliminating projection to the upper side of the cover. CONSTITUTION:A screw rod 24 for degree of coupling adjustment is screwed to a cover 23 and its head is built in a spot-facing 231. Since an inserting length of the tip of the screw rod 24 to a coupling degree adjusting hole 202 of a dielectric block 20 is determined to a prescribed length in advance, the rod with such a length can only have to be fixed with screwing and tightening, and if there is any difference in the degree of coupling, a screw is slightly moved or a position with a desired coupling degree is set with a long screw rod and the screw is replaced with one having a length suited to said length. Since the head of the rod 24 is inserted to the part 231 formed on a cover 28, no projection exists on the cover 28. Thus, the block 20 is made small in size and light in weight, the adjusted parts are less, the number of components is reduced and a dielectric filter with excellent productivity can be obtained.

IPC: G06T15/40
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To reduce the shape defining manhour in a line width processing mode where a thick line is changed to a medium or thin line, etc., by turning data made into the variable into an integrated variable in every shape that undergoes the collective hidden line processing for the parts, areas, etc. SOLUTION: When a designer selects a standard/broken line display pattern out of a display pattern menu, the hidden line processing is carried out to turn a head part A, a shaft part B and a screw part C into broken lines. When a head part/solid line display pattern is selected, the hidden line processing is carried out to display only the part A and not to display other parts B and C. In screw part/broken line display pattern, the hidden line processing is carried out to show the part A in a solid line and the parts B and C in broken lines respectively. Thus, the line type of a certain part can be changed for the hidden line processing of only the part just by selecting the no display, the broken line, etc., as the display form of the part.  As a result, the change processing jobs can be omitted in such cases where plural entire graphics having the same shape and partly different line types are sequentially defined or a graphic once defined is partly deleted, etc.

They are ideally the same signal at the overlapped parts. They are analog signals by D/A converters 140, 176 and interpolation filters 142, 178 and compared by a voltage comparator 180. When the data of said range is identical (same phase), a zero is outputted. An error quantity detection circuit 182 outputs a low level signal and the control circuit 172 recognizes the matched phase.
