Title: Manufacture of semiconductor device
Inventor: SUZUKI MIEKO
IPC: H01L21/768
Filed: 1992-04-28
Abstract: PURPOSE:To form a flat normal pressure CVD silicon oxide film in which air bubbles do not exist independently of a substratum, by performing fluorine compound gas plasma processing after a silicon oxide film is deposited, or by ion-implanting fluorine compound and surface-treating the silicon oxide film. CONSTITUTION:After a first silicon film 2 is formed on a silicon substrate 1 by a CVD method, a lower layer aluminum wiring 3 is formed. A second silicon oxide film 4 is deposited by a plasma CVD method. The surface of the second oxide silicon film 4 is etched by about 0.1mum with a cathode coupled system dry etching equipment using CHF3 and O2. A third silicon film 5 is deposited by a normal pressure CVD method wherein the flow rate of ozone and TEOS is set to be 20:1. By the surface treatment using CHF3 and O2, substratum dependency of the surface of the deposited third silicon oxide film 5 is eliminated and the surface is flattened. A through hole is opened and then an upper layer aluminum wiring 8 is formed.

Title: Rotary stencil press with ink overflow preventing unit
Inventor: MATSUSHITA TAKESHI
IPC: B41L13/04
Filed: 1995-05-08
Abstract: PURPOSE: To provide a rotary stencil press preventing the overflow of ink by effectively and efficiently separating a plate cylinder from an ink roller at the time of ending printing. CONSTITUTION: A high rigidity part 15 having higher rigidity than that of a front part is former at the rib 14 protruding at the terminating end 17a of the opening 16 of a plate cylinder body 12 to the outside as a center, and a gap is provided between a plate cylinder 10 and an ink roller 40 in a natural state to be disposed. Even if the cylinder 10 brought into pressure contact with a press roller 50 during printing is not brought into pressure contact with the roller 50, it remains in contact with the roller 4 by the sticking force of the ink 46. After printing, when the part 15 of the cylinder 10 arrives at the contact region 13a, the cylinder 10 increases its restoring force to the natural state to separate from the roller 40. Since excess ink is not supplied from the roller 40, the ink is prevented from being leaked from the rear end 32 of a print base sheet 30.

Abstract: PURPOSE:To make assembly work to install a choke in an output part easy and obtain good characteristics by forcedly fitting a circular platelike periphery part in the wall plane of an outer conductor, and joining them completely by hard-soldering. CONSTITUTION:A relatively long cylindrical part 22A extending toward the axis of a tube is formed in the periphery part of a circular platelike part of a metal piece 22a to be fixed in a sealing metal 21 (an outer conductor). Using such metal piece 22a and when a metal piece 23a is forcedly fixed in the lower side of the metal piece, the shoulder part of the metal piece 23a is stuck to the lower end of the cylindrical part 22A of the metal piece 22a and thus the metal piece is positioned. Both metal pieces are previously plated with slightly thick copper or silver and the plating layer is melted by heating the fixed part to carry out soldering of the forcedly fixed part. Consequently, a choke which suppresses unnecessary higher harmonics of specific frequency from leaking is positioned easily and precisely in good figure and high function to cost ratio is obtained.

Abstract: PURPOSE:To prevent an oil leak from the connection part of an oil pipe and the fracture thereof by providing a cylinder unit, a tank chamber, a hydraulic pump and a spring and control valve for shut-off within a single cylinder block. CONSTITUTION:When a control valve 20 is actuated and a hydraulic pump 26 is operated in closing a switching part, oil to a tank chamber 24 flows into both sides of the operating piston 19 of an operating cylinder chamber 16 and an accumulator cylinder chamber 17. As a result, a rod 21 moves together with the operating piston 19 due to a pressure differential and the switching part 20 is closed. On the other hand, when the control valve 20 is selected to the off-position in opening the switching part 20, the operating cylinder chamber 16 and the tank chamber 24 becomes continuous to each other via the control valve 29 and an accumulator piston 22 is pushed with the force of an energized spring 25. As a result, oil in the accumulator cylinder chamber 17 flows to the operating cylinder chamber 16 and concurrently therewith, oil in the operating cylinder chamber 16 flows to the tank chamber 24 via the control valve 29, thereby opening the switching part. According to the aforesaid construction, the fracture of an oil pipe and an oil leak from the connection part thereof are prevented.

Abstract: PURPOSE:To produce a high quality picture without being affected by variations in an X-ray intensity, by suppressing variations of the voltage when an inverter starts by controlling the pulse width of the inverter. CONSTITUTION:A control circuit 20 supplies a voltage application signal VS and a pulse width signal EW to a gate circuit 13 of an inverter 3, and also sends a command signal SH for opening or shutting a shutter to a shutter 21. The pulse width signal EW controls the amplitude of input current to the inverter 3 in such a manner that, when the inverter 3 is actuated the width of a voltage which is applied to an X-ray tube 6 is narrow but it becomes broader, successively to suppress variations in the input voltage to the inverter. After the input voltage to the inverter 3 has been stabilized and the amplitude of the current has reached a desired value, a command signal SH for opening the shutter 21 is output to open the shutter 21. A stable intensity of X rays can be obtained by applying the X rays from the next operation of the inverter.
