IPC: G03F7/26
Filed: 1986-05-15
Abstract: PURPOSE:To execute printing with high accuracy by subjecting a printing roll on which a coating film of a photosensitive resin for a photoresist and coating film for an original plate consisting of a photographic emulsion are formed to be scanned with light to form a halftone original plate of the photographic emulsion, then etching the same by full-surface exposing and developing.

IPC: H02P29/00
Filed: 1988-05-10
Abstract: PURPOSE:To prevent a disk from rotating at an abnormally high speed by switching the output signal of an automatic phase controller to a predetermined holding voltage when the rotating speed of the disk exceeds the controlling range of the controller due to a disturbance. CONSTITUTION:When any disturbance is applied to the rotation control system of a disk motor 2, read from a disk and a signal fed to an automatic phase controller APC 7 exceeds the controlling range of the APC 7, a step-out signal A is output from a synchronization detector 15 to a microcomputer 20. If a counterelectromotive force (e) detected by a counterelectromotive force detector 16 exceeds a reference voltage V1, a signal B is output from a comparator 17 to the microcomputer 20. When the microcomputer 20 receives the signal A and the signal B, it switches a changeover switch 19 from a to b, and feeds a voltage V2 so set as to correspond to a lower speed than the rotating speed of the disk 1 at the time of normal state in a driver 8.

Title: Prescribed position stop control system of synchronous motor
Inventor: MATSUDA ISAO
IPC: H02P3/24
Filed: 1983-06-21
Abstract: PURPOSE:To stop a synchronous motor at the prescribed position by a simple control system by fixing the pulse width of a pulse train of phase outputs, and applying repeatedly equal width pulses to the motor, thereby generating a stationary magnetic field from an armature winding. CONSTITUTION:An inverter 2 is controlled by a PWM controller 4.

Title: Schottky barrier type semiconductor device and manufacture thereof
Inventor: TSUDA NAOYUKI
IPC: H01L29/872
Filed: 1979-08-30
Abstract: PURPOSE:To contrive the improvement in the electrostatic withstanding characteristics of the Schottky barrier type semiconductor device by forming at a low slope the junction surface between a Schottky barrier metal and an Si substrate from the inner peripheral surface of an insulating film over the recess of the surface of the substrate. CONSTITUTION:An N type epitaxial layer 2 is formed on an N<+> type Si substrate 1, an SiO2 5 and a CVD SiO2 6 are superimposed thereon, an opening is perforated thereat, and an N type layer 2 is exposed thereon. The exposed surface is heat treated at high temperature, and an SiO2 3 having round corners in the recess is formed thereon. In this case the layer 2 of the exposed part is recessed in dish shape to be further reduced in thickness, and this thickness determines the series resistance of the diode. Then, the SiO2 3 is etched, the etching step is finished immediately after the layer 2 is exposed on the bottom of the opening, and the Schottky barrier metal 4 is attached thereto. Since no corner is produced in the recess according to this configuration, destruction owing to the electric field concentration hardly occur. Since the surface of the substrate is removed in recess shape, the contamination on the junction surface with the metal is removed, and  the insulating film on the periphery of the junction surface is reduced in thickness, and the electric field concentration can hardly occur.

Title: Surface acoustic wave filter for transmitting fm television signal
Inventor: ETSUNO MASAYOSHI
IPC: H04N5/44
Filed: 1991-05-16
Abstract: PURPOSE:To effectively maintain differential gain and differential phase characteristics even when the smoothness of the characteristics is deteriorated by specifying the lengths of an input inter-digital converter and an output inter- digital converter and a distance between the centers of both the converters. CONSTITUTION:It is defined that the center distance between the input inter- digital converter 5 and the output inter-digital converter 6 in the propagation direction of a surface acoustic wave is L1, the lengths of the converters 5, 7 are L2, L3, the propagation speed of the propagating surface acoustic wave is V, and the frequency of a color subcarrier in an FM television (TV) signal is fs. In this case, L1=V/fs set up and at least one of L2, L3 is set up less than V/fs. Thereby the center distance L1 becomes the inverse of the frequency fs and the period of a ripple appearing on the pass band of frequency characteristics becomes fs. Even when a ripple is generated due to the influence of a direct wave and the smoothness of characteristics is deteriorated, the deterioration of the differential gain and differential phase characteristics at the time of transmitting a TV signal to be transmitted can be suppressed.

Title: Image forming device
Inventor: OKUDA KOICHI
IPC: G03G15/02
Filed: 1990-04-27
Abstract: PURPOSE:To prevent the density irregularity of an image or the width irregularity of a line from occurring by executing the constant-voltage control of an electrostatic of an electrostatic charge member with the aid of a DC voltage detected when the electrostatic charge member corresponds to the image forming area of a body to be electrostatically charged. CONSTITUTION:An electrostatic charge roller 2 is controlled in terms of a DC constant- current control in a rotating term that it corresponds to the non-images forming area surface of a drum 1. Then, the DC voltage at this time is detected. When the DC constant-voltage control is started, the image forming of a firs sheet by laser scanning and exposure is executed. Besides, the electrostatic charge roller 2 corresponds t the image forming area surface of the drum 1 and the surface of the drum 1 is electrostatically charged under a DC constant-voltage control state. Therefore, the electrostatic potential of the drum 1 is made to be fixed regardless of the variation of the resistance of the roller 2. As the result, even when the roller 2 and a pin hole on the surface of the drum 1 are brought into contact with each other at the time of forming an image, the DC voltage with respect to the roller 2 is not changed because it is not the constant-current control. Thus, the irregularity of the density does not occur at the contact time of the roller with the pin hole.
