Abstract: PURPOSE:To miniaturize a device by providing a knob composed of a projecting part energized upward and freely extended/contacted on the top surface of the housing case of a transfer corona discharger, and forming a pressing part at a position opposite to the knob of a photosensitive body unit. CONSTITUTION:A transfer unit is housed in the housing case 21 and for improving operabilities at the time of attaching/detaching the transfer unit, plate-shaped knob parts 22 are provided on both ends of the top surface on the housing case 21.

When an upper unit is fixed, the knob part 22 is housed in the recessed part 21a of the housing case 21 and projects from the top surface of the housing case 21 when the upper unit is removed. Since the knob part 22 provided in the housing case 21 is level with the top surface of the housing case 21 at the time of fitting the upper unit, it is unnecessary that the recessed part into which the knob part 22 is fitted, is formed on the upper unit 21 and a space required for the upper unit can be reduced.

Title: Automatic control system
Inventor: NAKANO MICHIO
IPC: G05B11/36
Filed: 1989-08-09
Abstract: PURPOSE:To constitute a repeat control system with high accuracy by storing the change of the control deviation of a closed loop automatic control system as a non-temporal function. CONSTITUTION:An analog shift register 5 of M stages which performs a shift operation of one stage at every input of a pulse P, and a pulse oscillator 6 mounted on the controlled system 4 of a motor or a compressor rotating system and which generates M pulses per rotation are provided. At such a case, the control deviation for each rotational position is stored in the analog shift register 5 during one rotation. Repeat control is performed so that control can be performed for the deviation stored in preceding rotation at each rotational position in the next revolution more accurately than the present rotation as increasing the rotation by performing the similar operation. In such a way, a targeted value or a waveform of disturbance remains unchanged for the rotational position even when the rotating speed of the motor and a cycle in point of time changes, which prevents impairment of control effect.

Title: Lighted button switch
Inventor: ITO SHOJI
IPC: H01H9/16
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To form a button into small size and to intensely irradiate light of an LED to an upper part in the button, by integrally forming the operating button and an emitter of LED or the like made movable. SOLUTION: A tip end of an operating shaft 20a is fitted to be inserted to a cavity of a button 10 consisting of a translucent member to form a cavity in the inside. Here is previously mounted an emitter 16a in a recessed part in an upper end of the shaft 20a, to be positioned in the inside upper part of the button 10. The emitter 16a is connected by lead wires 44 to a printed board 42 connected to a switch circuit part 12 through a switch circuit case 18. In this way, since a space between an upper end of the emitter 16a and an upper part reverse surface in the button 10 can be formed to a prescribed distance or less, the button 10 can be intensely lighted. That is, a position of the emitter 16a of LED or the like is fixed relating to the button 10, to move the emitter 16a with the button 10, consequently to eliminate necessity for a member and space necessary in the past, and irradiation light can be intensified while the button 10 can be miniaturized.

Title: Line relieving method and ring network using the method
Inventor: MAEJI NAOKI
IPC: H04L12/437
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a switching system capable of most shortening a route at the time of line relief by switching a transmission line to be used in a line unit and partially relieving the line incapable of being relieved by conventional techniques when transmission faults occur at plural spots by permitting the coexistence of two kinds of ring switching and span switching systems on the network at the same time. SOLUTION: In this line relieving method in the case of transmission fault occurrence on a ring network, a fault detection node, which detects the fault, transmits fault information to the other node on the ring network and the fault detection node judges whether the switching of the line is required for the fault or not and judges whether the switching is span switching using a reserve line or ring switching using a ring line. In the case of span switching, the request of switching to the line to use the reserve line is outputted to the adjacent node on the side of the same fault detection.

Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To receive weather information by simple operation by receiving a signal distributed by a specific frequency band and switching a telephone line only when detecting a weather information identification number. SOLUTION: A signal sent to a weather information identification number detector 10 and a number to store within optional extraction storage device RAM 13 are compared by a central processor CPU 11 and at the time of detecting the weather information identification number, the signal of cutting off a communication telephone line 4 is sent to the relay part 6 of a line interface part 5 through an input/output device I/O 14 to cut off this. Then weather information is received only by a weather information identification number detection line 7, and a weather item number to store in RAM 13 and receiving weather item number are compared with each other to send the command signal of matched numbers to a display unit to display weather information. Thus, the weather is simply received only by the key operation of a receiving terminal witching unit.

Title: Message added system digital signature method and verification method therefor
Inventor: CHA YOUNG TAE
IPC: H04L9/32
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To reduce the length of a signature by adopting the method that a first part of the signature is obtained based on a hash code generated in relation to a message and on a random number generated at the time of signature and a latter part of the signature is obtained based on a cryptographic key of a person signing the signature, a random number generated at the signature time and the first part of the signature. SOLUTION: After the digital signature method is started, at first a hash code H(M) is generated based on a message M in the step 100 on one hand, and a code g<k> is calculated based on a random number K and a variable (g) in the steps 110, 120 on the other hand. Then a modular (p) is calculated by multiplying the H(M) with the code g<k> in the step 130, then a first part R of the signature is obtained by cutting off the result of the arithmetic operation above into Lq-bit in the step 140. Then a latter part S of the signature is calculated by using a cryptographic key X of the signer in the step 150, and the parts R, S are merged in the step 160 to obtain the signature ΣR||S. This signature Σ is added to the message M in the step 170 and the resulting message is transmitted together with a signature verification key Y.  Thus, the length of the signature is decreased.
