Abstract: PURPOSE:To obtain a diaphragm wherein the boundary between a strain generating part and a fixing part becomes a nearly regular octagon, by performing alkali anisotropic etching by using an etching mask whose aperture is in the form of a cross. CONSTITUTION:In the central part of a diaphragm mask 13, an aperture part 14 opened in the form of a cross is arranged, whose periphery is covered with an SiN film. Each side of the aperture part 14 is arranged and formed so as to coincide with the crystal axis (110) of a silicon substrate 12, and subjected to alkali anisotropic etching. In the course where etching of the crystal face (110) of a bottom 16 progresses, the silicon substrate 12 corresponding with corner parts A is etched, and inclined surfaces 16 appear. On the other hand, a crystal face (111) whose etching rate is low appears as inclined surfaces 17.

Title: Engine ignition timing control device
Inventor: IMAZU SHIGEKI
IPC: F02D41/16
Filed: 1985-04-25
Abstract: PURPOSE:To ensure the stability of idle operation and to aim at enhancing the economy of fuel consumption, by providing an idle detecting means and by providing an ignition timing control means receiving a detection signal from the detecting means, for setting the ignition timing toward the spark advance side for a predetermined time just after transition into the idle operation. CONSTITUTION:When the operation of an engine is shifted into its idle operation from its decelerating operation, a spark advance term IGA is added to a basic ignition timing to set the ignition timing toward the spark advance side for a certain predetermined time, and the basic ignition timing is set initially after the above-mentioned predetermined time elapses. If the ignition timing is set toward the spark advance side, the rotational speed of the engine tends to increase, a control valve 12 in a bypass passage 11 is controlled by a control unit 14 in the direction in which the rotational speed increases. Accordingly, the amount of intake-air decreases as a whole, and therefore it is possible to reduce the fuel consumption. Thus it is possible to aim at enhancing the economy of fuel consumption while the stability of idle operation is ensured.

Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To appropriately mount a test piece on a material testing machine without deflecting or folding the test piece by bending the soft test piece in the short side direction, holding it and conveying it to a specified position. SOLUTION: A pad 1a consisting of a silicone rubber is provided on one end of a vacuum pad 1, and an air suction device is connected to the other end. After the vacuum pad 1 is lowered to the position where the pad 1a is brought into contact with a surface of a test piece TP, the suction device is operated to suck the test piece to the pad 1a. When the test piece TP is sucked to the pad 1a, the test piece TP is bent in the short side direction by a bending guide at the same time. An elevating/lowering cylinder 7 is operated while the bend test piece TP is sucked to the pad 1a, the test piece TP is suspended, and mounted on a material testing machine. Since the rigidity of the curved test piece TP is increased, no deflection due to its self weight is generated. And the specified material test can be carried out.
