IPC: F15B11/00
Filed: 1985-03-12
Abstract: PURPOSE:To control the pressure of a secondary passage to low pressure close to zero by leading the pressure of the a primary passage to the pilot passage of the pilot chamber of a main valve and the pressure the the secondary passage to the pilot passage of the pilot chamber of a pilot valve which opens and controls the former pilot passage.

Title: Electrode for electrochemical etching
Inventor: HIRATA MASAKI
IPC: H01L21/302
Filed: 1986-03-07
Abstract: PURPOSE:To prevent the leakage of currents without using a waterproofing agent when a silicon substrate is etched through an electrochemical method by burying a terminal material consisting of the specific quality of material to a 'Teflon(R)' material with a groove holding one part of the silicon substrate pushed in through an opening. CONSTITUTION:The high concentration layer 6 side of a silicon substrate 5 is directed in the direction that it is brought into contact with an electrode, and inserted into an electrode hole 3 in a groove 2 for a Teflon material 1 through an opening, and the high concentration layer 6 is brought into contact with a bent section 4a in a terminal material 4 in which phosphor bronze is plated with nickel-gold. When an anode for a DC power supply is connected to the terminal material 4 and the silicon substrate 5 is dipped gradually in an etching liquid, the high concentration layer 6 side is electrically etched, and only a low concentration layer 7 is left. Even when the lower section of the 'Teflon(R)' material 1 is dipped in the etching liquid, the etching liquid does not intrude because a groove 2 section is fast stuck to the silicon substrate 5. Accordingly, leakage currents do not flow even when a contact section between the silicon substrate 5 and the electrode is not sealed by a waterproofing agent.
