Title: Paper sheet discharge device for office equipment
Inventor: OTAKE YOSHIHISA
IPC: B65H29/22
Filed: 1988-09-28
Abstract: PURPOSE:To perform positively the discharge of paper sheets into a discharged paper stocker by forming the title device in such a way that the elastic blades of an impeller push the terminus part of the paper sheet forcibly out to the inlet part of a discharged paper stocker when the terminus part is separated from a discharge roller. CONSTITUTION:A paper sheet reaching a discharge part 37 is pressed to a discharge roller 36 by means of a discharge presser bar spring 35 and conveyed up to the inlet part 41 with the tip of the paper sheet 2 inserted between the elastic blades of an impeller 39. As a result, even if a preceding paper sheet still exists, such a case that the tip of the following paper sheet 2 goes over the terminus part of the preceding paper sheet 2 never occurs. Accordingly, the paper sheets 2 are delivered to a paper discharge tray 42 precisely in order. When the terminus part of the paper sheet 2 is separated from the discharge roller 36, the elastic blades 40 of the impeller 39 push its terminus part out to the paper discharge tray 42 side. As a result, the paper sheet 2 is prevented from being stopped in the process before being completely discharged into the paper discharge tray 42.

Title: Preference controller for frame memory access
Inventor: HATTORI HIROSHI
IPC: G06F13/16
Filed: 1990-09-17
Abstract: PURPOSE:To simplify the software constitution and to increase the drawing speed by providing a preference control circuit to set the priority among those accesses given from a drawing control part, a CPU, and a refresh timing circuit. CONSTITUTION:A preference control circuit 4 prepares five types of signals, i.e., a request signal, a queuing state signal, a start signal, an under-execution signal, and an end signal in regard of the accesses of a CPU 2 and a drawing control circuit 1. Each access starts with the request signal and ends with reception of the end signal. When the request signal is inputted, the presence or absence of the signals higher in rank than its own one is checked. If no higher rank signal exists, the request signal is used as the start signal and the under- execution signal is outputted. Then the access of the under-execution signal can monopolize a V-RAM 6. In the same way, five types of signals are applied also to the access of a refresh timing circuit 3 of a higher rank. Thus the CPU 2, the circuit 1, and the circuit 3 start in the order of higher ranks and the execution of them are controlled despite the presence of a refresh request signal.

Title: Automatically cutting and winding device for band-like object like film, etc.
Inventor: SUZUKI TSUTOMU
IPC: B65H19/28
Filed: 1984-11-19
Abstract: PURPOSE:To reduce roughness on the surface of a core by rotatably installing a pair of retaining rolls oppositely to a cutter across a band-like object to enable a cutter to enter between said rolls at a cutting position and enabling a very thin adhesive tape to wind a film. CONSTITUTION:When a predetermined winding length is reached, a turret 7 rotates in the direction of A, an arm 17 is elevated and a cutter 16 reaches an operating position, and a new core 5 starts to rotate at a synchronized speed. Here, control is made to bring the stop position of the cutter accurately close to a winding line E to make the length of the end (a) of a film preceding the winding line E, minimum. Then, an arm 15 is lowered, the film1 is pressed against a cutter 16 and cut by means of rolls 13, 14 at a high speed, the film 1 is attached onto the core 5 by means of the roll 13 to change winding, the arms 15, 17 are returned after the change of winding is completed,and anew mill roll is wound on a core 5. Thus, since the film is retained by rolls at the time of cutting,the value of adhesive force of the core to a film can be made small, enabling an adhesive tape of less than 10mu to be used, while reducing the generation of ragged surface of a core.

Title: Spindle drive controller of spinning machine
Inventor: YOSHIDA OSAMU
IPC: D01H1/26
Filed: 1992-08-19
Abstract: PURPOSE:To provide the subject controller capable of readily changing the speed change pattern of the rotational speed of a spindle in a spinning machine. CONSTITUTION:An average speed gradient theta is calculated from the production quantities and the rotational speeds of the spindle respectively at the starting point (N1) and the terminal point (N4) in an acceleration interval from start of winding till the maximum rotary speed of the spindle. Speed gradient ratios (r1, r2 and r3) are set so that the average speed gradient theta may be equal to the average value of speed gradients theta1, theta2 and theta3 in the respective acceleration intervals (S1, S2 and S3) obtained by dividing the acceleration interval and the set values are stored. A controller outputs a speed direction to an inverter based on the production so that the rotational speed of the spindle may be in accordance with the speed gradients theta1 to theta3 calculated by a central processing unit from the speed gradient ratios (r1, r2 and r3) and the average speed gradient theta. The inverter can change the speed of the drive motor based on the speed direction and can control the rotational speed of the spindle.

A high-speed image signal operating and processing section 6 operates and processes the data for every picture element at high speed, and finds image information about the soldered side of the object 3 at respective angles. The image information so obtained is put into the form of data as detailed image information about the soldered state and edited as shape data. Thereafter, a recognition and judgement section 8 evaluates the soldered state of the object 3 for each case corresponding to a fine conditional change in soldering, and a change in data dispersion.

Filed: 1988-09-29
Abstract: PURPOSE:To make the thickness of a semiconductor oxide film which is formed at one time thin and to embed a deep step part flatly by repeating the formation and the flattening of the semiconductor oxide film. CONSTITUTION:A wiring layer 12 and an insulating film 13 are formed. A thin reflow film 16 is deposited so that a void is not formed at a step part. The film 16 undergoes reflowing by heat treatment, and a reflow film 16b without a void is obtained. Then, a reflow film 17a is deposited on the film 16b. The film 17a is made thicker than the film 16a. The film 17a undergoes reflowing, and a reflow film 17b is obtained. Since the film 16b is formed so as to embed the step part to some extent, there is no void in the film 17b even if the film 17b is thicker than the film 16b. The surface is made approximately flat. Thereafter, a contact window is formed in the films 17b, 16b and the like. The film 17b undergoes reflowing again, and the shoulder part of the contact window is made smooth.

Title: Manufacture of silicon-germanium film
Inventor: TAKANO HIROSHI
IPC: C01B33/06
Filed: 1991-09-25
Abstract: PURPOSE:To prevent the occurrence of a point defect, such as haze, etc., so as to prevent the deterioration of such electric characteristics of a device as mobility, lifetime, etc., by controlling the oxygen concentration in a silicon- germanium film lower than a specific value. CONSTITUTION:When a P-type Si1-xGex film is grown by using metaboric acid (HBO2) as an impurity source, the oxygen concentration in the film has growing temperature dependency. When the growing temperature exceeds 540 deg.C, the oxygen concentration starts to abruptly decrease and becomes lower than the concentration which is originally contained in an Si substrate at a growing temperature of 570 deg.C. When the growing temperature becomes 630 deg.C or higher, the oxygen concentration decreases until it becomes lower than the background level of oxygen for SIMS analysis. When the oxygen concentration is lower than the original oxygen concentration originally contained in the Si substrate, point defects hardly occur and the mobility and lifetime of a device do not deteriorate. Therefore, the oxygen concentration in the silicon-germanium film can be controlled to <=1X10<18>cm<-3> by controlling the growing temperature.
