Title: Fixing device for color image forming device
Inventor: TSUDA TAKESHI
IPC: G03G15/01
Filed: 1990-09-19
Abstract: PURPOSE:To prevent the offset of a toner layer on a sheet by increasing the sheet carrying speed of ejecting rollers in a specific range with respect to the sheet carrying speed of a fixing roller when the toner of two or more different colors is used to form an image. CONSTITUTION:When the toner of two or more different colors is used to form the image, the sheet carrying speed of the ejecting rollers 33 and 34 is increased in the range of 10 - 20% with respect to the sheet carrying speed of the fixing roller 23. Thus, since the sheet carrying speed of the ejecting rollers 33 and 34 is increased by 10 - 20% with respect to the sheet carrying speed of the fixing roller, and the ejecting rollers 33 and 34 are amplified within the range capable of a normal action, the tensile force of a sheet by the ejecting rollers 33 and 34 is increased. Therefore, the tensile force can remove the sheet P after the toner is fixed without winding it on the fixing roller 23 against the sticking force of the toner fixed on the sheet to the fixing roller 23. Thus, the offset of the toner layer on the sheet is prevented.

Title: Lamellar scavenging 2-cycle internal-combustion engine
Inventor: JIYO HANDOU
IPC: F02B25/14
Filed: 1983-12-30
Abstract: PURPOSE:To devise improvement of the thermal efficiency of an engine and quality of the exhaust gas by providing a sub-scavenging passage to connect a sub-scavenging port and the inside of a suction pipe in the downstream of a non- return valve, and forming a partition for dense and thin fuel-air mixture in the suction passage. CONSTITUTION:The suction of an engine is carried out by a reed valve 8 and a piston 18 which opens and closes a suction port 16. A partition to separate dense and thin fuel-air mixture is provided in a suction passage 9. When main scavenging ports 15 are opened in a scavenging stroke, the fuel-air mixture in a crankcase 17 flows into a cylinder 5 through the main scavenging ports 15. When a pair of subscavenging ports 12 are opened dence fuel-air mixture in the suction passage 9 flows into a sub-scavening passage 11 through an opening 10 and is supplied inside the cylinder 5 through the sub-scavenging ports 12. In this way, the blow-bye loss of fresh air is reduced and the thermal efficiency of the engine and the quality of the exhaust gas are improved.

Title: Objective lens actuator
Inventor: KUDOU TSUKANE
IPC: G11B7/09
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To cause a spindle to collide with a supporting piece so as to offset oscillation, by causing the natural oscillation frequency of a collision damper unit including a leaf spring and the spindle to coincide with the oscillation frequency of the supporting piece in a focusing direction. SOLUTION: A collision damper unit 10 is provided to protrude in parallel along a focusing direction with respect to a supporting piece 2b of a body portion 2a. Such collision damper unit 10 includes a leak spring 10a and a spindle 10b provided in an integral manner at the distal end of the leaf spring so that the collision damper unit 10 may collide with and move away from the supporting piece 2b at the time of oscillation. The natural oscillation frequency of the collision damper unit 10 is caused to coincide with the oscillation frequency of the supporting piece 2b in the focusing direction, by adjusting the spring constant of the leaf spring 10a and the weight of the spindle 10b. In addition, a portion where the supporting piece 2b collides with the collision damper unit 10 is treated by wear-resistant processing.  When the supporting piece 2b oscillates in the focusing direction at the time so operation, the collision damper unit 10 oscillates at the same frequency as that of the supporting piece 2b and with the opposite phase, and the spindle 10b collides with the supporting piece 2b, thus offsetting the oscillation.

Title: Drum motor controller for magnetic recording and reproducing device
Inventor: MURATA NORIYASU
IPC: G11B15/473
Filed: 1988-10-05
Abstract: PURPOSE:To improve the phase control accuracy of a drum motor by performing phase control by using a low-accuracy phase control system when the drum motor is actuated, and then switching the control system to a high-accuracy phase control system and controlling the phase of the drum motor. CONSTITUTION:When the drum motor is actuated, the motor is out of rotary phase greatly, so a data selector 26 is switched to the side of an input terminal P and a phase error signal DPE is generated based upon the counted value of a PG phase comparing counter 22 latched by a latch circuit 23 to perform the phase control of the drum motor. Then when the phase of the drum motor enters a set error range under the phase control, the state is decided by a phase lock decision circuit 25 and the data selector 26 is switched to the side of an input terminal F. Then the phase error signal DPE is generated based upon the counted value of the FG phase comparing counter 31 latched by a latch circuit 32 and sent to a drum motor driving circuit. Consequently, the phase of the drum motor is controlled under high-accuracy phase control.

Abstract: PURPOSE:To prevent inversion which arises in a contacting electrification member and to uniform the electrification processing of an image carrier by setting an abutting angle of the contact electrification member with respect to the image carrier smaller than an abutting angle of a cleaning member with respect to the image carrier. CONSTITUTION:The abutting angles are acute, which is made by abutting surfaces of the contacting electrification member 2 and the cleaning member 6A with respect to the image carrier 1 and the tangent of the abutting surface of the image carrier 1.

The abutting angle theta2 of the contacting electrification member 2 with respect to the image carrier 1 is set smaller than the abutting angle theta1 of the cleaning member 6A with respect to the image carrier 1. By such constitution, cleaning of the surface of the image carrier 1 is made efficient and peeling- off can be prevented which arises in the contact electrification member 2 without adhering residues acting as a smoothing agent in the abutting part with respect to the image carrier 1. In addition to that, the surface of the image carrier 1 is uniformly electrified and processed.

Filed: 1989-09-26
Abstract: PURPOSE:To fix output power, to almost remove the loss in a transformer and to reduce heat generation in the transformer or electronic parts by switching and changing input side inductance in accordance with input voltage. CONSTITUTION:When a commercial power supply 1 of 200V is connected, the voltage rectified and smoothed by a rectifier bridge 4 and a capacitor C1 exceeds the Zener voltage of a Zener diode D3, a transistor (TR) Q1 is turned on, and a light emitting diode D1 is turned on. Since a TR Q2 is turned off, a relay is held at the OFF state, an armature R1 is held at the connected state to a contact S1. Thereby, 200V voltage is impressed to coils L1, L2 in series. When the commercial power supply 1 of 100V is connected, the Zener diode D3 is not turned on and the relay is turned on. Thereby, the voltage is impressed only to the coil L2.

Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To achieve cost reduction by adopting a constitution wherein two kinds wire-wound thermometers are inserted into a container all together so that the results of the measurements agree with each other, and by decreasing the processing of the container for inserting and attaching the wire-wound thermometer into the container in an oil-tight mode. SOLUTION: A dial-thermometer type heat sensitive part 31 and a temperature measuring resistor 32, which is the resistor-type heat sensitive part, in the wire-wound thermometer 3 are contained in one heat sensitive tube 34.
