Title: Fixing device for electrophotographic device
Inventor: OGANO AKIRA
IPC: G03G15/20
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To provide the fixing device of a roller system that a roller member made large-sized and made heavy in weight is easily and inexpensively exchanged and defective fixing is eliminated on the entire surface of printing paper. SOLUTION: Relating to the fixing device 30, a holding member 31 holding at least either of a peeling layer or a nip forming layer on an outer peripheral surface is made attachable and detachable into/from a cylindrical member 32 having rigidity on an outer periphery side. An exchange work is easily and inexpensively executed because it is needed to replace only the holding member at an exchange time. Also, the cylindrical member is supported, rotated and driven from the inner peripheral surface by plural rollers 33, so that a necessary nip width is maintained even in the case that the entire length of a roller part is long.

Title: Speed controller of motor
Inventor: NISHIZAWA YUJI
IPC: H02P29/00
Filed: 1985-04-17
Abstract: PURPOSE:To stably control the speed in a high performance by varying a speed loop gain in response to a motor speed. CONSTITUTION:An operational amplifier 3 supplies a voltage V2 corresponding to a deviation between a speed command signal S1 and the actual speed value S2 of a motor through a divider 20 and a power amplifier 4 to a motor 5. A function generator 18 outputs a voltage V3 corresponding to the output voltage Vr of a return signal S2 to the divider 20. The divider 20 calculates the ratio of the output voltage V2 of the amplifier 3 to that V3 of the generator 18, i.e., V2/V3, and outputs the output voltage V21 to the amplifier 4. thus, when the speed increases, the gain G decreases. Accordingly, the control is stabilized at high speed, and the gain G is not reduced at low speed, thereby generating no insensitive zone.

Abstract: PURPOSE:To increase the accuracy of detection, by providing a higher-mode fiber for a detection section converting variable due to mechanical bending force or vibration into an amount of light and cutting off the light of higher mode produced through the mechanical vibration by means of a lower mode fiber. CONSTITUTION:A higher-mode fiber 24 functioning as a detecting section is fixed to a pipe line 31 with a packing 32 and a fixture 33. A vortex BU is alternately generated at the left and right sides at the downstream of a device toward the flow FL and the fiber 24 is oscillated with a force FO orthogonal to the flow FL. The light in a light emitting element 21 is propagated in the fiber 24 through a lower-mode fiber, the fiber 24 is bent with the external force FO, and the propagated light is converted from the lower to higher mode. The light of the higher mode to be converted is cut off at the lower-mode fiber 22 at the  feedback side and the amount of beam propagating the fiber 22 is changed. The flow rate can be obtained with high accuracy by detecting the change in the amount of beam at a photodetector 25.

IPC: H04L7/08
Filed: 1983-05-10
Abstract: PURPOSE:To automatically detect discrepancies among plural framing codes, by serial-parallel converting framing codes from repeatedly transmitted information and detecting coincidence of the framing codes from the converted output. CONSTITUTION:A serial data signal (a) inputted into a terminal 12 is converted into a parallel signal by means of a clock signal (b) at a seral-parallel circuit 1 and the output is impressed upon a coincidence detecting circuit 2. The output (d) of the circuit 2 becomes a coincident pulse of a high level only when the output (d) coincides with any one of framing codes FC A, B, and C, and outputs (e), (f), and (g) of the circuit become pulses for generating high-level coincident pulses having error correcting capabilities, only when they coincide with the framing codes FC A, B, and C, respectively. FFs 5-7 are reset by a selection start signal (c) from a terminal 13 and a high-level pulse (e) is latched at the FF5. The combination of a reset circuit 3 and AND gate 4 generates a coincident pulse extracting pulse (i) from the signals (d) and (c) and releases the latched condition of the FF5, and then, outputs an FC signal (k) to the coincident FC A from an AND gate 8.

Title: Power converter
Inventor: KOUNO MICHIO
IPC: H02M3/155
Filed: 1980-06-18
Abstract: PURPOSE:To stabilize an output voltage by providing an auxiliary winding to the choke coil of a step-down type converter and by obtaining a voltage proportional to the output voltage of the converter by rectifying a voltage developed across the winding. CONSTITUTION:A choke coil L2 is provided with an auxiliary winding N2 and a voltage obtained by subtracting an output voltage V0 from an input voltage VIN is so applied that a positive potential is generated at the beginning of the winding N1 in a period L2 when a transistor TR is conducting. In a period when the TR is cut off, a voltage V0 is so applied that a negative potential is generated at the beginning of the winding N1. Therefore, a voltage V0' obtained from a voltage developed across a winding N2 through the half-wave rectification of a diode D2 is in proportion to the output voltage V0, so the voltage V0' is detected instead of detecting the voltage V0 to stabilize the output voltage.
