Abstract: A method for element isolation utilizing insulating materials in a semiconductor substrate is proposed. In this method an oxidizable material layer of polycrystalline silicon or the like is formed and then the oxidizable material layer is selectively oxidized, using an oxidation-proof mask thereby forming a thick oxide layer (6). Thereafter, the oxidation-proof mask is removed and unoxidized oxidizable material below the mask is perpendicularly etched off, leaving part of the oxidizable material (3") which is then oxidized to form together with the thick oxide layer an element isolation. This invention further proposes a semiconductor device having element isolation layer whose bird's beak (A) is very small in length.

Abstract: @ For loading a record disc on the turntable of a record-disc player, a loading device is provided which comprises a movable loading support (32, 34, 36) for supporting a holder (38) containing a record disc (22). The loading support is slidably supported between two fixed, parallel, vertical guide plates (28 and 30) by pins (50 and 52) an the support sliding in L-shaped guide slots (54 and 56) in the guide plates, each slot having a vertical section extending downwardly from a horizontal section. Slidably supported on the outer sides of the guide plates for horizontal movement in vertical planes parallel to the planes of the guide plates are two drive plates (68) having inclined slots (78 and 80) in which the pins on the loading support slidably engage. By cooperation between the inclined slots and the pins the drive plates can move the loading support; guided by the L-shaped slots in the guide plates, along a horizontal path and down a vertical path to deposit the record disc supported on the loading support on the turntable. Pivotally supported between the guide plates is an arm (58) carrying a pressure member (66) for urging the loaded disc into a centred position on the turntable. The arm is pivotable between an inoperative position (Figures 1 and 6) and an operative position (Figure 7) about a horizontal axis and comprises two plates (60) which are movable in vertical planes adjacent the guide plates and which are each formed with a recess (64) which, when the arm is in the inoperative position, is located beside and coincides with the horizontal section of one of the guide slots in the adjacent guide plate at a position such that when the pin on the loading support which engages in that guide slot reaches the end of the horizontal section of the slot during the loading movement of the loading support, the pin enters the respective recess, and as the pins move down the vertical sections of the respective guide slots they cooperate with the recesses to move the arm to the operative position.

Abstract: A liquid crystal display comprises a liquid crystal cell (1) formed by enclosing a thin layer (14) of a cholesteric liquid crystal material between slides (7, 8). A set of electrodes (9, 10) structures is formed on each slide (7, 8) so that voltages may be applied to the liquid crystal material (14) causing an observable display effect. Voltages are supplied to the electrodes in sequence by driver electronics (2, 3) under the control of a logic unit (4) which also controls a variable voltage source (6) supplying voltages to the drivers electronics (2, 3). To reduce the time taken to change displayed information the voltages applied to the driver electronics (2, 3) is reduced in value for a short period e.g. between a display refresh time and 30 milliseconds. The reduction in voltage level may be 90% or less of the normal value.
