Abstract: PURPOSE: To lessen the scatter of discharge energy even against the change of a machining gap, by an electric source apparatus for cutting a wire with an electric discharge, the apparatus including a combination of a voltage variable direct current power source, a high direct current power source, and main and subsidiary switch circuits.  
     CONSTITUTION: When the output S 3  of a discriminator 44 and the output S 1  of an oscillator 32 are given to a delay-differentiating circuit, the output S 4  of an AND gate 36 triggers and drives a vibrator 38. The output S 5  thereof drives to close a main switching circuit 30. After a sub-switching circuit 28 becomes conductive to energize the machining gap with an electric voltage E 1 , and a certain delay time has passed, the main switching circuit 30 is set to close or open according as an electric discharge has been generated or not. If a normal electric discharge is generated by the energized voltage E 1  from the first direct current power source 26, the discharge can be succeeded even if the second direct current power source 26 has a high output voltage and a high peak current capacity.

Abstract: PURPOSE:To manufacture a waveguide having an exact rectangular cross section by forming a circuit pattern by lithography and reactive ion etching on a heat resistance resin layer formed on a substrate, and using it as a mold for forming the waveguide. CONSTITUTION:A heat resistance resin layer 4 which becomes a mold is formed on a substrate 3, silicone which becomes a mask of the resin layer 4 is subjected to sputter coating thereon in the post-process, a photosensitive resist is subjected to spin coating, a mask puttern is exposed by ultraviolet rays, and development is executed.

Title: Damper
Inventor: KATSUMORI TEIJI
IPC: F16F9/06
Filed: 1979-02-23
Abstract: PURPOSE: To improve damping performance by providing a retainer separately for a sealing member which seals the inside and outside of the cylinder of a damper and giving hardness to the end of the substrate of a lip part only in the valve- closing direction, while keeping the part flexible enough in the valve-opening direction.  
     CONSTITUTION: When a piston rod 10 is thrusted into an inner cylinder 2, oil 12 in the chamber A is given pressure by a piston 19 and the pressurized oil flows into the chamber B through a communication port 15, bending upward the outer peripheral edge of a disc valve 16. On the other hand, the pressurized oil flows also into the reservoir chamber C via a communication port 14, raising the pressure of a gas 13 in the chamber C. By the rise in pressure, the lip part 20b of a valve body 20 is seated on a valve seat 4b so as to prevent the gas 13 from penetrating into the chamber B through the valve chamber D. On the occasion, as the end of the substrate 20c of the lip part 20b is reinforced by a retainer 23, the lip part 20b is prevented from being deformed by bending toward the inside in the radius direction due to the high pressure of the gas.
