Abstract: PROBLEM TO BE SOLVED: To realize high sensitivity of a position sensor for detecting the safety control release territory of a window, in a power window device performing safety control by detecting a caught-in state based on the opening/closing position of the window and the driving condition of a motor. SOLUTION: A pair of contacts 31, 32 are arranged on the side of a main gear 24 rotated by the output shaft 14 of a motor 9 operating to open/close a window. On an auxiliary gear 25 meshing with the main gear 24 through an interlocking gear 27 and rotating at different speed from the main gear 24, a conductive film 30 is arranged so as to be opposite to the contacts 31, 32. When the output shaft 14 of the motor reaches a fixed rotational quantity by relative rotational operation of the main gear 24 and the auxiliary gear 25, namely when the window is moved up to the fixed opening/closing position, the contacts 31, 32 are contacted with the conductive film 30 to output an electric signal. An safety control release territory can be detected at accuracy of 1:1 to the moved quantity of the window, and it is unnecessary to arrange a position sensor in the vicinity of the window.

IPC: G02C7/14
Filed: 1989-03-15
Abstract: PURPOSE:To bring a display and an input device in apparent proximity to each other and to improve the efficiency of an input work by providing prisms to a lower half part of a visual field and forming the virtual image of a lower object adjacently to the image in the upper half part of the visual field by the refraction of the prisms. CONSTITUTION:The spectacles for the work are constituted of glass 1 in the upper half part of the visual field and the prisms 2 in the lower half part. When an operator wears the spectacles, the operator is able to view the display device 7 in a direction 81 and to view the input device 6 which is intrinsically ought to be viewed in a direction 82, as the virtual image a apparently in a direction 83 by the refraction of the prisms 2. The display 7 and the input device 7 which are apart from each other in actuality appear to be adjacent to each other. The operator is, therefore, able to alternately view the display device 7 and the input device 6 even without moving his head. Just a slight movement of the line of vision is, therefore, necessitated. The efficiency of operator's input work is improved and his fatigue is lessened.

Filed: 1986-03-20
Abstract: PURPOSE:To reduce a frame synchronizing restoration processing signal without spoiling the basic function by ANDing paired detection signals of plural pattern detection circuits and applying the frame synchronization restoration pattern to different frames from the result. CONSTITUTION:When a high-order group digital signal Sdh is inputted to a signal split circuit 1, the signal is frequency-divided and the 1st and 2nd signal strings are outputted. When the 1st signal string is inputted to the 1st and 2nd pattern detection circuits 2(1), 3(1) of the output system No.1 side and the 2nd signal string is inputted to the detection circuits 2(2), 3(2) of the system No.2 side, every time the circuit 2(1) detects the 1st split frame pattern signal, the detection signal is outputted and every time the circuit 3(2) detects the 2nd split frame pattern signal, the detection signal is outputted. When the detection signal is outputted from the circuits 2(1), 3(2), a synchronizing restoration circuit 6 applies the synchronization restoration processing based on the signal of an AND circuit 4. On the other hand, in the conversed case, the circuit 6 uses signals of an AND circuit 5 to apply the processing.
