IPC: B26F3/00
Filed: 1990-06-29
Abstract: PURPOSE:To effectively reduce the turbulent flow of high-pressure water in a focusing chamber and improve the flow characteristic by providing a valve body reciprocated in the penetrating direction of an inlet passage and opening or closing the inlet passage opened to an inlet chamber. CONSTITUTION:The inlet passage 13 of a device main body 1 is opened or closed via a valve body 2 via the reciprocation of the valve body 2 by a reciprocating system 3, and the high-pressure water guided from the inlet 11 of the device main body l at the time of an opening action is injected as ultra-high- pressure water from a nozzle 15 via an inlet chamber 12, an inlet passage 13 and a focusing chamber 14. The valve body 2 is reciprocatably arranged on the inlet passage 13 side to the focusing chamber 14, not in the focusing chamber 14, thus the turbulent flow of the high-pressure water in the focusing chamber 14 is reduced, and the flow characteristic of a fluid to the nozzle 15 can be improved.

Abstract: PURPOSE:To conduct a test for the durability of the magnetic disc medium in a short time by measuring a time required for the magnetic disc medium coming to head crush through adjustment of the arrangement of an air-flow direction adjusting member on the head arm of a magnetic head device. CONSTITUTION:The air-flow direction adjusting member 4 is constituted in such a manner that an air-flow direction adjusting plate 4b is supported by props 4a of the magnetic head arm 1 at an angle theta to the latter in the rear of the positions where a gimbal 2 and a magnetic head 3 are arranged and in the direction of the rotational advance thereof. By this constitution, the air moving in the direction of rotation in parallel to the surface of the magnetic disc, which is not shown in Figure, is disturbed forcedly to take the direction shown by an arrow and is taken to the gimbal 2 and the magnetic head 3. Then, the posture of the magnetic head which is lifted is disarranged due to the disturbance of an air film, and the height of the lift can not follow the disturbance of the air film and thus the head is brought into contact with the magnetic disc and led to the head crush in a short time.

Title: Method of polishing surface of hydrogen storage metal
Inventor: SHIGE TAKASHI
IPC: B24B1/00
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To restrict the quantity of hydrogen in the hydrogen storage metal, of which surface is ground, at a remarkably small value by limiting the moisture content of the grinding oil at the predetermined value or less. SOLUTION: Grinding oil, of which water content is small, is used as a grinding agent so that an active new surface to be generated at the time of polishing a surface of the hydrogen storage metal is not directly and repeatedly exposed in the grinding liquid and the moisture included in the atmospheric air. Absorption of hydrogen from the moisture to the hydrogen storage metal is thereby prevented. In the case of surface grinding of the hydrogen storage metal using the grinding oil, of which moisture content is low, when the grinding oil is eliminated after concluding the polish, the polished surface contacts with the atmospheric air, and a strong oxide film is generated thereon, and simultaneously, a little quantity of hydrogen is absorbed to the hydrogen storage alloy, but it is limited to once. Consequently, quantity of hydrogen to be absorbed to the hydrogen storage metal can be disregarded. Desirably, moisture content in the grinding oil is limited at 200 ppm or less.

Title: Automatic aperture control circuit of camera
Inventor: TAKAHATA HISATOSHI
IPC: G03B17/38
Filed: 1983-09-20
Abstract: PURPOSE:To prevent a camera which has a momentary stop-down photometery type aperture control means and an electromagnetic releasing means to malfunction by inhibiting aperture control for a specific time after the electromagnetic release starts operating. CONSTITUTION:An aperture AP is initially in a full open state, and a photometery circuit LC outputs a signal V1 corresponding to the opening of the aperture AP, ASA of a film, etc. The output V2 of a manually set shutter is initially less than V2. When a release SW1 is turned on, a latch LT1 generates an H-level to flow a current through a coil Mg1 for the start of stop-down operation, which is carried on by holding a driving circuit MD2 at L until a delay circuit DL1 generates an H output a specific time later. When the stop-down operation advances until V1=V2, an AND G2 generates an H output and a coil Mg2 inhibits the stop-down operation. Then, SW2 is turned off right before a mirror is elevated to hold a latch LT2 at H, SW3 is turned off to charge a capacitor MC to V1 corresponding to the shutter speed, and a shutter magnet Mg3 is excited to release the shutter. Thus, proper exposure is performed.

Abstract: PROBLEM TO BE SOLVED: To reduce the external size of the enclosure of a gas-insulated metal enclosed switchgear by protruding the fitting legs of saddles to the end sections of the cable connecting-side openings of a cover. SOLUTION: T-shaped bushings 2 are fitted to the upper surface of a flange 1d welded to the ceiling section of an enclosure 1 and fitting saddles 3A are fixed to the bushings 2. The height of a fitting cover is made slightly higher and strip-like fitting flanges 6 are symmetrically welded to the lower sections of the front and rear ends of the fitting cover. Since the bushings 2 fixed to the upper parts of a flange 1d can be brought nearer to each other when the bushings 2 are fitted in such a way, the width of the flange 1d and the depth of the enclosure 1 can be reduced. As a result, the area of the enclosure through which the bushings 2 are installed to an external wall is reduced by the protruded fitting legs and the external size of the enclosure 1 can be reduced.
