IPC: B23H7/26
Filed: 1987-12-17
Abstract: PURPOSE:To eliminate the uselessness of an electrode and eliminate the error of a worked shape and improve reliability by oppositely arranging a thin hole guide to a workpiece and installing an insulating grease guide for suppressing the electrode vibration between a revolving device and the thin hole guide. CONSTITUTION:A thin wire electrode 1 is installed onto a revolving device 5 installed onto a chuck 4, and is revolved, and then lowered, and the top edge is inserted into a grease guide 7 and a thin hole guide 2, and allowed to reach a workpiece 3, and working is carried out. Then, the top edge and the outer peripheral part of the thin wire electrode 1 are applied with grease as lubricating agent by a grase guide 7, and the thin wire electrode 1 is smoothly inserted into the thin hole guide 2, too. Further, since the grease of the grease guide 7 is not a fixed guide but a soft guide for the movement of the thin wire electrode 1, the vibration, deformation bending, etc. during the revolution of the thin wire electrode 1 can be suppressed. Therefore, the uselessness of the thin wire electrode 1 can be eliminated, and the error in the working shape can be suppressed, and high reliability can be obtained.

Abstract: PROBLEM TO BE SOLVED: To sense failure of a system correctly by sensing the water level in a water tank and the quantity of water being flown over the water tank and judging whether a failure is present in a makeup water supply system or not based on the sensed water level and the overflow volume and the control state of makeup water. SOLUTION: A water level sensor 310 and an overflow sensor 320 are provided and a supply valve 330 is controlled by means of a controller 340 depending on the sensor outputs. The controller 340 judges whether or not the water level sensor 310 or the supply valve 330 breaks down based on the sensed water level and the overflow volume and the open/close state of the supply valve 330. It is judged that the supply valve 330 breaks down if the overflow volume exceeds a reference level and the supply valve 330 is closed. If the overflow volume exceeds the reference level, the supply valve 330 is opened, and the sensed water level is lower than a reference level, it is judged that the water level sensor 310 breaks down and an alarm 350 is actuated.

Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To realize a highly reliable semiconductor device in which generation of leak current is suppressed. SOLUTION: A storage capacitor 10 has such a cross-section as the side faces 11s of a lower electrode 11 approach each other from the lower end toward the upper end, with respect to the central axis of the storage capacitor 10 to form an upper end outer circumferential face 11c intersecting the upper face 11u and the side face 11s.

Consequently, a stress concentration field occurring in a capacitor insulation film 12 is relaxed and generation of leak current can be suppressed. Since the lower electrode 11 has a trapezoidal cross-section, the corner of the lower electrode 11 between the upper end outer circumferential part and the lower end outer circumferential part is made obtuse.  Consequently, a stress concentration field in the capacitor insulation film 12 occurring at the upper end outer circumferential part and the lower end outer circumferential part is relaxed and generation of leak current can be suppressed furthermore.

Abstract: PURPOSE:To check the presence and degree of a variation in water lever in a non- testing section, caused by leakage between an packer and the wall of a hole by monitoring a result detected and indicated by a pressure sensor for detecting water pressure in the non-testing area. CONSTITUTION:After start of a pump 23, the pressure of filling which is indicated at an A-channel on an indicator 6 is adjusted to a prescribed value by means of a pressure adjusting valve 25, and then wafer is filled in a testing section T through a boring rod 22 and a packer 3. Simultaneously, an indication at a B-channel is monitored, and a variation in water level in the hole in a tensile test section N is checked. Thus, the pressure of filling is directly detected a pressure sensor 4 in the lower part of the testing section T, and accordingly, it is possible to eliminate the necessity of a ground-measured pressure value in which a pressure loss caused by a boring rod 22 is considered. Then, a filling pressure and a filling volume at any of filling pressure values set by the pressure adjusting valve 25 are obtained when the filling volume becomes constant, and accordingly, a lugeon value and a critical pressure are obtained from a filling pressure-filling volume curve. Thereby, it is possible to surely know the variation in water level in the non-testing section N, and the water-tightness of the packer 3 with convenient work.
