Filed: 1987-05-15
Abstract: PURPOSE:To prevent a film from isolating at the time of growing the film by forming a protective film of a thin film transistor by a CVD method using mixture gas of a-Si:H-NH3-H2. CONSTITUTION:An Mo gate electrode 2 is formed on a glass substrate 1, covered with two layer film 3 of an a-Si:H and Si3N4, superposed with an Si layer 4, and patterned with a predetermined channel width. A source electrode 5 and a drain electrode 6 are formed to form a thin film transistor 10. Then, an Si3N4 protective film 11 is formed by a CVD method with mixture gas of three components of a-Si:H-NH3-H2.

Title: Absolute position detector
Inventor: OKA YASUO
IPC: G01D5/249
Filed: 1988-05-17
Abstract: PURPOSE:To shorten the read-out time of one frame and to improve the responsiveness by reading out only a necessary pitch element without reading out all picture elements. CONSTITUTION:A signal charge from a photodiode 5 is transferred to a vertical shift register, and the signal charge is transferred to a head register 6. To the register 6, a switching element 7 of an FET is connected, and also, by the next clock which the signal charge of the register 6 has reached, the signal charge is swept out to a ground line 8. The element 7 is set to ON state selectively by an output signal of a horizontal address decoder 9, and the signal charge which has passed through the element 7 is supplied to a comparing circuit 11 through a charge voltage converter 10. To the circuit 11, a threshold voltage is supplied 12, and a binarized image pickup signal is taken out. This image pickup signal is supplied to the decoder 9, and an address of a picture element for executing read-out is designated. In such a way, only the picture element required for deriving absolute position information is read, therefore, the read-out time of one frame is shortened, comparing with reading out all the picture elements of an image pickup element 21, and an output delay time can be shortened remarkably.

Title: Liquid seal vibration isolation rubber device
Inventor: SATORI KAZUTOSHI
IPC: F16F13/26
Filed: 1994-05-10
Abstract: PURPOSE:To simplify external control of an internal pressure by a method wherein a part of a wall part by using which the liquid chamber of a rubber block is formed forms a hydraulic control plate and movement thereof to the interior or the exterior of the liquid chamber from the outside is controlled. CONSTITUTION:When an air pressure in a control space 26 is regulated through drive of the air pump 27 of an external air control device, a hydraulic control plate 12 is moved to control an internal pressure in a first chamber 8. Since, when the thick section part 14 of the plate 12 makes contact with a case member 15, the plate 12 is hardly deformed, a high dynamic spring state is produced, working liquid effectively flows through an orifice passage 34, and fluid resonance occurs to provide damping characteristics. When a control space 26 is released to the atmosphere, in a case comparatively low vibration is inputted in the first chamber 8, the thin section part of the plate 12 is resiliently deformed to absorb vibration, whereby a low dynamic spring state is produced. Since the internal pressure of the first chamber 8 is controlled through movement of the plate 12, the increase of an internal pressure owing to input vibration is suppressed and a dynamic spring constant is decreased.

CONSTITUTION:Continuous recording paper (a) is prevented from floating up by a retainer board 46 in the part from a send-out port 41 to the vicinity of a movable stopper 5, while its float-up is detected by a float-up detecting device 49 in the part between a cutting device 35 and the send-out port 41 and a paper sending device 30 is controlled by the detected signal. And, when the float-up is detected, the speed of the paper sending device 30 is lowered while increasing its speed when the detection discontinued, thereby, enabling recording paper (a) to be fed with a proper loosening in the part between a recording paper send-in device 8 and the paper sending device 30. Accordingly, the loosening being too large causing jamming or slippage causing unclear printed letters, is prevented and the float-up detecting device 49 which is provided on a feeding device A itself enables the wide application of the feeding device A to various recording devices.
