Title: Production of rapidly cooled metal strip by single roll method
Inventor: SATO TORU
IPC: B22D11/06
Filed: 1990-09-19
Abstract: PURPOSE:To resolve the problem of nozzle clogging caused by lowering of molten metal temp. by widening the gap between a nozzle and a roll to the specific value or more at the time of developing partial clogging in an injection hole of the nozzle and then again, setting the gap suitable value after melting the clogging part. CONSTITUTION:When the paddle 4 just below the nozzle 1 is monitored with a telecamera, it is observed that after 0.03sec from the first injection, three splashes 3 are splashed backward in the progressing direction of a strip and one in these is solidified on the roll surface and comes to the paddle part while being brought on the surface of a roll and the partial clogging is developed at the tip part of the nozzle. Then, by immediately shifting the nozzle and widening the gap to 0.5mm, as the molten steel is caused to flow in the whole width of the injection hole at 7sec after rising the nozzle, the nozzle is returned back to the original gap, and after that, trouble is not occurred so that the strip can be produced and coiled. The time from the development of partial clogging in the nozzle to the production of strip at the stationary position is 25sec. Therefore, gap distance in order to eliminate the nozzle clogging is made to be >=0.3mm.

Abstract: PURPOSE: To safely clean a windowpane so as to make this transfer device shiftable as being sucked on the window surface in the optional direction by setting up the half of legs out of four legs being free of contact or separation to or from a contact surface in the one direction and the other half freely rocking motion in a direction orthogonal with this one direction, respectively.

In succession, the suction cup 7 is displaced again and it is contacted with the contact surface of the windowpane and sucked, while this rocking cylinder 5 is reset. Thus, since the totaled four legs 2a to 2d of the paired two sets mutually orthogonal in the rocking direction are selectively displaced in order, a movable carriage 1 is shifted in the optional direction, and thus a windowpane surface is automatically cleaned by a wiping tool mounted on this movable carriage 1.

Title: Thermal transfer recorder and facsimile device using the recorder
Inventor: YOKOYAMA MINORU
IPC: B41J17/02
Filed: 1988-10-04
Abstract: PURPOSE:To prevent contamination of a recording medium and enhance quality of recorded images by recording images while feeding the recording medium and an ink sheet in substantially the same direction at approximately equal velocities, and rewinding the ink sheet by a length smaller than an image- recording length after the recording of the images is finished. CONSTITUTION:When image data is recorded over a predetermined length L, which can be detected based on the number of energizing steps for driving a recording paper-feeding motor, a rewinding motor is driven to rotate through a motor-driving circuit, thereby taking up an ink sheet backward by an amount of, for example, (n-1)L/n. The take-up quantity can be detected based on, for example, the number of marks read by a sensor for detecting feed quantity. After image recording is conducted n times, ink sheet parts having a length of 1/n times the length of the ink sheet used have been used for printing (multi- time printing) one time, two times, three times..., respectively, from the right side. Thus, image recording is conducted while the recording paper and the ink sheet are fed in the same direction, unrequired transfer of an ink to the paper can be prevented, and image quality can be enhanced.

Filed: 1993-10-05
Abstract: PURPOSE:To provide a surface acoustic wave convolver of high performance that increases the degrees of freedom of combination between the electro-machanical coupling factor and the temperature dependency by junctioning together a semiconductor substrate and a piezoelectric substrate by the hydrophilic treatment and the overlapping heat treatment on each substrate surface. CONSTITUTION:A piezoelectric thin plate 2 is directly junctioned to a silicon semiconductor substrate 1 by the hydrophilic treatment of the substrate surface and the overlapping heat treatment. The plate 2 uses, for example, a 40 deg. Y-cut and X-axis propagating lithium niobate single crystal. The input electrodes 3 and 3' are comb-line electrodes which excite the surface waves and used for input of signals. Meanwhile an output electrode 4 is provided on the plate 2 and a ground electrode 5 is provided on the rear surface side of the substrate 1. In such a constitution, two input signals are applied to the electrodes 3 and 3' respectively. Thus the surface acoustic waves propagating in the directions opposite to each other cause the fluctuation of potentials on the interface of the substrate 1. Then the capacity of a depletion layer varies on the interface of the substrate 1, and the convolution of the input signal emerges at the electrode 4 by the nonlinearity of capacity change of the depletion layer.

Abstract: PURPOSE:To prevent the damage of a latent image carrier when the jamming of a sheet occurs or a jammed sheet is removed by turning a peeling pawl and a pawl holding member at around two shafts having different positions, in two steps. CONSTITUTION:This peeling pawl device is composed of plural members 4 and 5 having a turning spring habit in the same direction. Therefore, when the sheet P threads between the top end of the peeling pawl 5 and the latent image carrier 1, and is jammed between the latent image carrier 1 in the vicinity of the peeling pawl 5 and the paul it is turned against the spring habit. Further, when the jam is progressed, the member 4 connected with the peeling pawl 5 is turned against the spring habit. Thus, the turning around two shafts 7 and 10 having different positions in two-setps is carried out, so that a playing quantity is increased, when the sheet is jammed. Thus, the damage of the latent image carrier when jamming of the sheet occurs and the jammed sheet is removed can be prevented.
