Title: Multilayer wiring forming method
Inventor: YAMAHA TAKAHISA
IPC: H01L21/316
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To flatten an interlayer insulating film and to improve the yield of production of a wiring in the multilayer wiring forming method. SOLUTION: After wiring layers 36A and 36B have been formed on an insulating film 34 which covers the surface of a board 30, the insulating film 38 such as plasma CVD-SiO2 , etc., is formd covering the film 34, wiring layers 36A and 36B. After a hydrogensilsesquioxane resin film has been flatly formed on the film 38 using a rotary painting method etc., a ceramic-like silicon oxide film 40 is formed by heat-treating the above-mentioned resin film in an inert gas atmosphere. The film 40 is brought into a ceramic state by heat-treating the film 40 in an oxidizing atmosphere. Microscopic protrusions 40a are generated on the surface of the film 40.  After the insulating film 42a such as normal pressure CVD-PSG etc., which does not reflect the microscopic protrusions 40A, has been formed on the film 40, the insulating film 42b, such as plasma CVD-SiO2 etc., is formed, and a wiring layer is formed on the film 42b.

Patent JP-H0367090-A (JP)
Title: Rotary compressor
Inventor: NAGAGAWA MAMORU
IPC: F04C28/06
Filed: 1989-08-03
Abstract: PURPOSE:To prevent reduction in an achievement coefficient during operation and to obtain a good pressure balance during a shutdown by providing a balance groove on an end surface of a cylinder block, by forming a muffler chamber and an oil reserving chamber, and by making an opening end of the oil reserving chamber faced by the balance groove. CONSTITUTION:A lubricant supplied from an oil pump during operation flows out of the tip end of a bearing 6 through an interval between a shaft 4 and a main bearing 6 and is guided to an oil reserving chamber 16, and the lubricant which has been collected is guided by a balance groove 12 and fills it. Thus, refrigerant gas is prevented from flowing into a cylinder chamber 5a through the balance groove 12, which prevents reduction in an achievement coefficient during operation. Also, during a shutdown, as there is no oil supplied form the oil pump, the lubricant which has been collected in the balance groove 12 flows down along it, and high pressure refrigerant gas can be guided into the cylinder chamber 5a from the balance groove 12, which achieves a good balance between the high pressure side and the low pressure side.

Filed: 1982-11-22
Abstract: PURPOSE:To discriminate efficiently the arranging order of each transmission controller by a monitor controller by fetching a signal representing idle state transmitted from the down-stream of a loop and an address of each transmission controller added to the signal. CONSTITUTION:The monitor controller CST and plural transmission controllers ST(ST1-ST7) are connected in loop in series via transmission lines 3 and 4.

After the end of the set, the device CST transmits a signal representing the line idle state to the line 3 or 4 by a communication controller and a modulation circuit. Based on the signal indicating the line idle state from the upper stream, each device ST transmits the own device address set just before the transmission to the down- stream by adding the address to said signal. The signal transmitted from the down stream is fetched by the device CST so as to discriminate the arranging order of each device ST.
