Title: Idle speed control valve for internal combustion engine
Inventor: SUMITA MAMORU
IPC: F02M69/32
Filed: 1993-12-08
Abstract: PURPOSE:To reduce the fluid sound due to pressure pulsation, by providing a pressure pulsation absorbing means to absorb the pressure pulsation of a fluid at the upstream passage, in an idle speed control (ISC) valve having a valve hole to communicate the upstream passage and the downstream passage. CONSTITUTION:When a power is given to an electromagnetic coil 35 to excite it, a movable iron core 33 is attracted to a fixed iron core 31 side against a return spring 34 and extending a spring 38, so as to open the fluid communicating hole 37a of a pipe 37. As a result, the fluid branched from an intake pipe to a bypass passage is fed to an engine as a bypass air after passing through fluid passages 41b to 41c. In such an ISC valve, a pressure pulsation absorbing means which consists of a membranous elastic body 42 having plural fluid flow-in ports is provided so as to block the upstream of the fluid communicating hole 37a. Since the elastic body 42 is deformed by the pressure pulsation of the fluid, the pressure pulsation of the fluid is absorbed through the above deformation, so as to suppress the generation of fluid sound.

Abstract: PURPOSE:To prevent degradation in film forming efficiency by sputtering by adding gaseous nitrogen to gas at the time of forming an information recording medium having a recording film contg. carbon and hydrogen and metal, semimetal or semiconductor element by sputtering using a metal or semiconductor as a cathode in a specific atmosphere mixture. CONSTITUTION:The gaseous nitrogen 10 is added to the gas at the time of forming the information recording medium having the recording film 12 contg. the carbon and hydrogen and metal, semimetal or semiconductor element by sputtering using the metal, semimetal or semiconductor as the cathode 8 in the atmosphere of gaseous hydrocarbon 4 or mixture composed of the gaseous hydrocarbon 4 and rare gas 6. The species formed in the glow discharge state of the gaseous hydrocarbon and gaseous N2 are the chemical species of C-N and N-H systems and the carbon and reformed layers on the target react with the N radicals and H radicals generated in glow discharge to form the volatile gas contg. the carbon which is easily removable from the target. The materials to hinder sputtering are thereby prevented from depositing on the target and the degradation in the film forming efficiency by sputtering is obviated.

Abstract: PROBLEM TO BE SOLVED: To prevent a junction capacitance from being generated between a first conductivity-type impurity region and a second conductivity-type impurity region by a method wherein the first conductivity-type impurity region and the second conductivity-type region are constituted so as to be kept at the same potential. SOLUTION: In a semiconductor device 89, the lower electrode 79 of a MIS capacitor is composed of a P-type impurity region 76 and an N-type impurity region 78 formed inside the P-type impurity region 76. The P-type impurity region 76 and the N-type impurity region 78 are kept at the same potential through a first lower take-out electrode 72b and a second lower take-out electrode 81. When the device 89 is set in operation keeping the MIS capacitor floated off a GND line or in such a state that the lower electrode 79 of the MIS capacitor is not connected to a GND, the P-type impurity region 76 and the N-type impurity region 78 are kept at the same potential. Therefore, a junction capacitance is not induced between the impurity regions 76 and 78, so that the lower electrode 79 is lessened in junction capacitance, and a high Q value and high frequency characteristics are ensured.

Filed: 1994-12-13
Abstract: PURPOSE:To realize smooth operation while reducing the cost by providing a guide with a part for inserting and reversing a cable and a protrusion sliding on a cable. CONSTITUTION:Under a state where the shaft part 56 is turned in one direction relatively to the frame part 44, a cable 22 is pulled into a guide 21 while being reversed through a reversing part 73 thereof and wound around the shaft part 56.
