Title: Electrostatic charging device
Inventor: MIYAMOTO TOSHIO
IPC: G03G15/02
Filed: 1988-02-09
Abstract: PURPOSE:To prevent an electrostatic charging member and a body to be charged from being fixed and further to prevent toner from being fixed on the surface of the charging member by composing the charging member of a conductive rubber layer and forming a releasing film at the part in contact with the body to be charged. CONSTITUTION:A photosensitive drum 3 as the body to be charged rotates as shown by an arrow. An electrostatic charging roller 4 as the charging member is in contact with the drum 3 with specific pressure. The roller 4 is constituted by providing the conductive rubber layer 4b to a metallic 4a and further forming a surface layer 4c as the releasing film on its peripheral surface. Consequently, the charging member and body to be charged are prevented from being fixed and none of the curing agent in the conductive rubber of the charging member is never stuck on the body to be charged, so the toner is prevented from being fixed on the surface of the charging member to preclude a defect and an irregularity in electrostatic charging due to the filming of the toner on the body to be charged.

Title: Facsimile terminal
Inventor: HIROSE YUKINARI
IPC: H04N1/32
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To utilize received title information as information to manage transmission reception and for retrieval by configuring a facsimile terminal such that NSS information integrating the code information of the title information by an NSS processing means is transmitted together with image information in the case of transmitting the image information to a facsimile terminal of a transmission opposite party. SOLUTION: Communication with an opposite terminal is set up by starting a communication control section 8 and title attached image information is transmitted to the opposite terminal via a MODEM 14 and a network controller 15 together with NSS information that is to inform the facsimile terminal of the transmission destination of the capability of its own terminal. In this case, the processing to integrate title information in the title attached image information into the NSS information is conducted. Then the title information is simply transmitted to the opposite terminal as part of the NSS information. Since the opposite terminal receiving the information can obtain the title information of the received image information from the NSS information as code information, the opposite terminal can utilize the code information as reception management information.

Title: Gate driving circuit of gate turn-off thyristor
Inventor: IIDA KATSUJI
IPC: H03K17/732
Filed: 1983-02-28
Abstract: PURPOSE:To allow a simple circuit to perform overdriving and wide-width gating with a narrow-width signal and to eliminate interference between circuits by providing a wide-width on gate circuit, and turning a control thyristor for it on by an on gate transformer and off by an off gate transformer. CONSTITUTION:An on control signal turns on a TRTON at time t1 and the on gate transformer PTON turns on a thyristor SON for prevention against on/off interference to turn on a gate turn-off thyristor GTO. At this time, even the control thyristor SW is turned on to flow a current through a loop including the SW and GTO from a DC power source E, obtaining a wide-width on gate current (figure (b)). The on control signal is ceased at time t2 and the thyristor SON turns off, but the thyristor SW turns on to flow the wide-width on gate current continuously (figure (b)). An off control signal turns off an off TRTOFF at time t3 as shown in a figure (c) to apply a voltage to the off gate transformer PTOFF, and the current of a route shown by a solid line turns off the GTO (figure (d)) to turn on a TRSOFF for turning off the SW. Therefore, the current of the power source E, SOFF, and PTOFF power source E turns off the thyristor SW.

Abstract: PURPOSE:To make the inductive voltage a smooth continued value, lessen the deviation of the output value from the reference value under operation, and enhance the accuracy by tying two arbitrary points of the reference value of coil supply current as a function of time by an elliptic function curve. CONSTITUTION:Data of reference value is accommodated in a memory 3, and a power source 4 supplies current to a load coil 5 in accordance with the reference value. Reference value is given through intertalk by the use of a computer 1 and a CRT display 2. The diagram as illustrated is displayed on the display 2, and coordinates of Points P, Q and the gradient are given, and 4-degree simultaneous equations are solved by the computer 1 to determine the elliptic function [I=a+b{1-c(t-d)<2>}<1/2>]. By the use of this function the numerical data about each time are obtained by the computer 1 and stored in the memory 3. Accordingly, Points P, Q are tied together smoothly when the power supply is in operation, and the voltage LdI/dt becomes continuous with respect to the inductive load, and the deviation of the output value from the reference value is lessened.

Output signals from the monitoring device 11 are outputted as control signals 12a and 12b to a governing valve 3 and a motor B for driving a turning device 9. Especially, when the eccentric amount of the rotor shaft of a steam turbine 4 is larger than the set value of an eccentric amount as a starting condition, a turning operation is performed by actuating the governing valve 3 or a warming valve so as to supply a small and proper amount of steam to a steam turbine main body. Thus, the eccentricity of the steam turbine rotor shaft is corrected at an early time, a time of reaching the starting condition is shortened and a suddenly and frequently changed power demand is coped with.

Abstract: PURPOSE:To prevent weaving bars from occurring by changing over an operation parameter to a shockless parameter so as to provide a higher produced torque than the rated value before completing start-up and the rated value after the completion using an inverter device interposed between a power source and a motor. CONSTITUTION:When a loom is started up, an operation parameter is changed over to a shockless parameter through an inverter device, interposed between a power source and a loom motor and equipped with a smoothing means for changing over the operation parameter to the shockless parameter so as to provide a higher produced torque of the aforementioned loom motor than the rated value during a period just after the start-up to completion and the rated value after outputting the signal of completed start-up. Thereby, the scope for occurrence of a time zone in which the motor causes a passive state recognized in conventional contact circuits in changing over the operation parameter is eliminated.

Abstract: PURPOSE:To prevent shape faults by predicting vertical direction deflection of the work rolls based on the direction and value of tangential driving force of the small diameter work rolls, then correcting the set value of a shape control actuator based on this predicted values. CONSTITUTION:When the schedule of the plate thickness rolling reduction and the base material plate crown are given, the target plate crown required for a i-th pass is obtained by a prescribed equation. On the other hand, the i-th pass rolling load is obtained by a given work roll diameters, plate thickness and the inlet and outlet sides plate thickness of the i-th pass, inlet and outlet sides tensions, deformation resistance of the rolled stock and the friction coefficient between the work rolls and rolled stock. Similarly, torques of the work roll shafts at the i-th pass are obtained and the roll driving tangential force is obtained by the equation. Further, because the plate width and the roll diameter are given, unknown numbers in the equation are only bending forces FW, FI of the work rolls and intermediate rolls. The value FI at each pass can be determined assuming FW = constant, or conversely, FW is determined assuming FI = constant.
