Title: Charged particle optical system
Inventor: KURODA KATSUHIRO
IPC: H01J37/141
Filed: 1987-12-23
Abstract: PURPOSE:To make it possible to deflect a charged particle beam easily, by a large angle and at a high speed by disposing at least one lens means between a deflection means which causes a large angle deflection and a sample and further disposing a means which causes a small angle deflection between the lens means and the sample. CONSTITUTION:A deflector 6 is disposed between lenses 3, 4 while another deflector 7 is disposed between the lens 4 and a sample 5. The deflector 6 deflects a charged particle beam 2 by a large angle while the deflector 7 by a small angle. In order for the charged particle beam 2 deflected with the deflec tor 6 by a large angle to pass through the center of the lens 4, the deflector 6 is constituted of deflectors 61, 62 and swings the beam 2 again to the original path. The lens 4 is of a multi-lens construction. This arrangement enables a small deflection aberration without disposing the deflectors 6, 7 within the lenses 3, 4 and to cause the charged particle beam to strike on the sample at right angles. As a result, a device is obtained which requires a deflection at a high speed and by a large angle.

Title: Thermistor sensor
Inventor: HIRAI MICHIO
IPC: G01K7/22
Filed: 1992-12-03
Abstract: PURPOSE:To obtain a thermistor sensor which is thin, light-weight and shows a small heat resistance at a substrate by using an alumina substrate manufactured with the use of a sol-gel method as the insulating substrate. CONSTITUTION:In a thermistor sensor 20, an alumina substrate of not smaller than 0.03mm and not larger than 0.4mm thickness which is manufactured by a sol-gel method with using metallic alkoxide is emnployed as an insulating substrate 22 to form a heat-sensitive body. Therefore, in comparison with a thermistor sensor using a conventional alumina substrate, the sensor 20 becomes thinner and moreover lighter by the amount whereby the substrate 22 is reduced in thickness. A heat-sensitive body 24 is formed on the substrate 22. The sensor 20 is provided with electrodes 26 and lead wires 28 formed at both ends of the heat-sensitive body 24. Since the substrate is formed of high-purity alumina, it has a large thermal conductivity. Therefore, the heat conduction of the substrate 22 is improved and the heat is conducted with good efficiency. Besides, since the surface of the substrate is less rough and smooth, a suitably uniform and flat thin film can be formed particularly when the thermistor sensor is formed of a thin film.

Abstract: PURPOSE:To decide a wiring region between blocks by wirings of signals except for setting of an operation mode of a peripheral circuit and to reduce the area of an internal circuit region by disposing a generator for a signal for setting the operation mode of the circuit as a plurality of peripheral circuits on the periphery of a semiconductor chip. CONSTITUTION:A generator for a signal for setting an operation mode of other peripheral circuit is disposed in a mode signal generating peripheral circuit block 3, and not disposed in an internal circuit block 2. A mode set signal of the peripheral circuit is wired to pass through the interior of the block and to circulate in a semiconductor chip. Accordingly, a signal wiring for transmitting a mode input signal to be applied from the exterior to the block, and wirings for transmitting the output of a mode set signal generator in the block to the mode set signal wiring of the peripheral circuit are eliminated. Thus, the area of the region of wirings between the blocks is reduced.

IPC: E02D17/04
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To improve support force by correcting the opposed face of an earth retaining wall and a waling by utilizing mutual sliding of spherical faces. SOLUTION: The wedge plate 50 of a back-filling tool is driven to contract a coil spring in a coil spring housing cylinder 23, and an interval between a waling side flat plate 20 and an intermediate inclined plate 30 is widened at a prescribed interval. When the protrusion-like spherical face of an earth retaining side protrusion plate 40 and the recess-like spherical face of the intermediate inclined plate 30 are mutually slid, the upper end of an outer screw type bolt 82 is moved in the cylindrical opening of the earth retaining wall side protrusion-like plate 40, and a large-sized washer 62 is moved in a notch 42 as it is slid therein. Thus, the sliding range of the protrusion-like spherical face and the recess-like spherical face can be adjusted by adjustment of the area of the cylindrical opening or the notch 42.  Thereby the opposed face is in a state where it is completely parallel and stress can be transmitted through the whole of the opposed face by laying an earth retaining back-filling tool between the waling and the opposed face of the earth retaining wall unparallel in the horizontal and vertical directions.

Abstract: PURPOSE:To prevent disturbance in synchronism or reproduction of unclear image on a television redeiver of a tape recorder by previously superposing a predetermined DC voltage at an output terminal of a booster means and then boosting an input power supply voltage at a quite high rate. CONSTITUTION:Upon turning a power switch 1 ON at time t0, potential at an output node A of a rectifier circuit 5 rises and reaches a prescribed level at time t1.
