Filed: 1984-02-15
Abstract: PURPOSE:To make operator's completion processing unnecessary by providing a delay period between power source disconnection by the operator and power source disconnection on a system and by realizing a retract operation for a disk device during this period. CONSTITUTION:When an operator turns on a power supply of a disk system, a switch a1 is turned on and a power source circuit (c) is fed. When an a2 is energized, a delay circuit (d) drives a relay (b) after a delay period T, and the a1 and the relay (b) constitute a close loop. Next, at the time of power source disconnection of the disk system, the a1 is disconnected by the operator and the delay circuit (d) releases the relay (b) after sufficient delay period T for the retract action, when a generator circuit (e) detects a2 disconnection and generates a retract signal V only for a period of T, which applies an interruption to a microprocessor inside the disk device. The disk device realizes the retract operation by itself.

Title: Manufacture of semiconductor optical element, semiconductor optical element manufactured by it, and optical applied system using the element
Inventor: SHINODA KAZUNORI
IPC: H01L21/3065
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To reduce the residual damages on the surface of a semiconductor and side faces of a waveguide by dividing an etching process into a dry etching process involving ion irradiation and a successive dry etching process involving no ion irradiation. SOLUTION: Steps are formed on the surface of a substrate 1 by reactive ion etching. When the steps are formed on the surface of the substrate 1, damaged layers 7 are formed on the surface of the substrate 1 and side faces of the steps due to shocks from ions. After this first process, radical etching is successively performed by causing glow discharge from a mixed gas of methane and hydrogen. When the radical etching is performed, the substrate 1 is not damaged and the damaged layers 7 formed during the reactive ion etching can be removed, because no shock is given to the substrate 1 from ions. Therefore, the residual damages on the surface of the substrate 1 and side walls of a waveguide can be reduced.

Title: Electrifier for image forming device
Inventor: KANAME YOICHI
IPC: G03G15/02
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To prevent electrification failure and so on over a long period, without making a structure complex, by providing a means for the application of charges, having the same polarity as that of a DC current which is applied to a contact electrifying member, to the surface of an image carrier further upstream than the contact electrifying member in the direction of the movement of the image carrier. SOLUTION: A pincorotron 31, as the charge application means, which applies the surface of the photoreceptive drum 1 charges having the same polarity as that of a DC voltage which is applied to the electrifying roll 10 is provided further upstream than the electrifying roll 10 in the direction of the movement of the photoreceptive drum 1. The DC voltage having the same polarity as that of the DC voltage which is applied to the electrifying roll 10 is applied to the pincorotron 31 by means of a DC bias power source 30, so that the surface of the photoreceptive drum 1 is electrified by the discharge of the pincorotron 31.  As a result, even if foreign matters such as toner, which has slipped out, exists on the suface of the photoreceptive drum 1, the foreign matters are electrified to the same polarity as that of the DC voltage applied to the electrifying roll 10, electrostatic repulsion, therefore, acts between the electrifying roll 10 and the foreign matters, and they do not stick to it.

Title: Optical transmitter
Inventor: TOYAMA TAKAMICHI
IPC: H04J14/02
Filed: 1991-02-22
Abstract: PURPOSE:To improve the operability by devising the transmitter such that one input section is used in common even when an input signal type is changed and troublesome manual changeover is not required. CONSTITUTION:When a signal in the state of a video signal is inputted to an input terminal 1, an input signal deciding circuit 2 detects it that only a component of the video signal is in existence and sends a control signal to an automatic changeover switch 3A. The switch 3A receives the signal and switches itself to a changeover contact (a). Thus, the video signal is subject to FDM in an FDM circuit 4 together with a voice signal 5 and sent to an E/O conversion circuit 6 through a switch 3B, converted into an optical signal and sent to an optical transmission line. On the other hand, when the signal subjected to FDM is inputted to the input terminal 1, the circuit 2 decides the inputted signal to detect it that the component other than the video signal is in existence. Then a control signal to switch the switch 3A to the position of a switching contact (b) is sent to the switch 3A. The signal subjected to FDM inputted to the input terminal 1 through the switch 3A is directly sent to the E/O conversion circuit 6, in which the signal is converted into an optical signal and the result is sent to an optical transmission line.

Abstract: PURPOSE: To facilitate changing a socket and a rod by forming a rod head part, advanced into a socket of a rod, by crushing work into a flat plate shape over the downward from a rod side end part of the socket, so as to prevent plastic deformation of a lug-shaped part which is a rod receiving part of the socket. CONSTITUTION: A head part 3, advanced into a socket 2, of a rod 3 is formed by crushing work into a flat plate shape at least from a side end part of the rod 3 of the socket 2 over the downward. That is, a base end of the head part 3a of the rod 3 is arranged so as to protrude downward from a lower end part of a lug-shaped part 2b of the socket 2. In this way, even in the case that an overload of exceeding a design value acts by any reason in a wire rope 1 and a shackle rod 2b to cause plastic deformation inside the lug-shaped part 2b of the socket 2, since it comes into contact with a side surface of the head part 3a, biting into a lower side of the rod 3 is prevented. Consequently in the case of replacing the wire rope 1, separating the socket 2 and the rod 3 can be facilitated.
