Abstract: During sputtering for use in thin film deposition, anomalous discharge is prevented from generating between a target and a backing plate, and a target presser. In the target presser also serving as an earth shield and a deposition preventing plate, an insulating member staying in contact with the sputtering target or the backing plate is provided with a recess constituted of two or more different depths so that the recess does not come in contact with the sputtering target or the backing plate.

Abstract: An EL display in which expansion of dielectric breakdown occurring at any one of EL elements is inhibited. Scan electrodes are arranged to receive an offset voltage Vm at those instances other than during application of a scanning voltage thereto in a positive field, while a predetermined voltage is applied to data electrodes to prevent voltage from being applied to EL elements immediately after application of the scan voltage. Accordingly, even where dielectric breakdown occurs at any one of the EL elements due to application of a light emission driving pulse voltage, it is possible to inhibit current flow between the scan electrodes and the data electrodes to thereby inhibit further subsequent dielectric breakdown.

Abstract: In order to perform micromachining of a precision smooth curved surface on a workpiece, light emitted from a mercury lamp is transmitted through a photomask, Fourier transform lens, aperture material, and inverse Fourier transform lens, after which it is beamed upon the workpiece material to be surface-machined and a positive photoresist layer which is formed on the surface of the workpiece material. By means of the foregoing structure, the high-frequency optical components which are included in the light emitted from the mercury lamp and which may cause roughening of curved-surface machining are made to converge at a location away from the optical axis and are removed by means of an aperture provided thereupon, with the only the residual low-frequency optical components being transmitted through the aperture, and so the intensity profile of the light which is beamed upon the positive photoresist layer is smoothed and a smooth-surface curved surface is transcribed to the positive photoresist layer.

Abstract: A magnetic clutch has a driving-side rotating member for holding one of a magnetic substance member and a hysteresis member and rotating in asynchronization with a rotary shaft; a driven-side rotating member for holding the other of the magnetic substance member and the hysteresis member and rotating in synchronization with the shaft, the driven-side and driving-side rotating members being spaced apart on the shaft; and a device for regulating the rotation of the shaft with sliding friction caused by viscosity. Alternatively, the driving-side rotating member can rotate in synchronization with a rotary shaft, and the driven-side rotating member can rotate in asynchronization with the shaft.

Abstract: A color electrostatic recording apparatus in which a color picture can be reproduced without misconvergence of colors through actuating a recording head to expand or contract and compensating the recording position of each image in accordance with the information of expansion/contraction and meandering of a recording medium which has been detected by reading register marks provided on the side edges of the recording medium.

Abstract: In a flat-shaped display apparatus has a face plate, a rear plate, side plates, and necessary electrodes therein, a supporting plate and plural supporting rods which are connected to an edge of the supporting plate at intervals of a certain distance are provided between the face plate and the rear plate. The supporting rods are made of metal and all bonded parts are covered by guide plates so that no adhesive is exposed to the electron beams. Therefore, over-scanning of the electron beams can be made, without the electron beams impinging on the adhesive thereby enabling effective distortion compensation.

Abstract: An electrode assembly for display apparatus is disclosed. A plurality of electrodes of different rigidities are provided between a cathode and a fluorescent material through coupling spacers. Plural kinds of coupling spacers are prepared in each of which the materials of a substrate metal, an insulating layer and a glass frit are different from each other and the proportional thicknesses of these components are varied to the extent that the intervals between the electrodes of different rigidities are not changed are prepared. An electrode block is completed by arranging the electrodes and the spacers such as to cancel the rotating moment around the neutral axis of the electrode block and joining them by means of calcination. The assembling accuracy of the electrode block is heightened very advantageously for positional accuracy with respect to the fluorescent screen.
