IPC: H05H1/46
Filed: 1991-06-27
Abstract: PURPOSE:To simplify constitution by providing a work coil grounded in its center tap on the output side of a matching device to sum power in the work coil. CONSTITUTION:A RF signal transmitted from an oscillator 1 is amplified by a preamplifier, then divided into two by a power divider 3, and transmitted to first and second power amplifiers 4a, 4b with the phases being shifted by 180 deg.. The RF power amplified by the power amplifiers 4a, 4b is transmitted through transmission lines 5a, 5b, subjected to impedance conversion by a matching device 6, and then sent to a work coil 7. The work coil 7 is grounded in its center so that a power is summed in this coil 7 when a waveform of reversed phase is sent from both ends of the work coil 7. Thus, the power sum and impedance conversion in the course are not required, and the constitution is simplified.

Title: Conveyor for sheet material
Inventor: MIYAKE MATSUYUKI
IPC: G03G15/00
Filed: 1981-10-02
Abstract: PURPOSE:To prevent damaging of transfer paper even when the preceding end of the transfer paper under transferring is grasped by a fixing means in press contact therewith by providing a conveying passage provided with a recess changing gradually in the width direction of the transfer paper between a separating means for the transfer paper and the fixing means. CONSTITUTION:A transfer material transferred with toner images by a corona discharger 6 is separated forcibly from a drum 1 by a separating belt and a separating means using a roller 7 and a roller 8. A conveying passage 9 on the down stream side of the separating means has a U-shaped recess. The separating means side of the separated transfer paper is guided on the side 10a of the passage 9. On the other hand, the inner side of the transfer paper ascends once like a chain line then advances by gravity along the side 10b of the recessing surface in the lower part of the conveying passage. Therefore, the preceding end on the separated side of the transfer paper arrives at the press contact line of a fixing device 11 which is deviated by an angle theta with respect to the angle at a right angle to the conveying direction of the transfer paper, and the pulled side is accumulated along the surface of the recess, thus preventing the adverse influence of the tension by the pulling upon the transfer paper.

Filed: 1985-07-17
Abstract: PURPOSE:To improve the centering precision by providing elastic materials which are brought into contact with a rib and are engaged in a collet an are held in a cone and pushing claws of the collet open independently of one another by elastic materials. CONSTITUTION:When a flange 16 is pushed down by an arm, a collet assembly falls along a guide 17. Each claw F of a spring 18 compressed by a cone 26 is brought into contact with each claw D of a collet 25 independently. Even if the dimension precision like the out of roundness is varied among claws of the collet 25, this variance is absorbed by a flat spring 24, and all claws of the collet are brought into contact with an inside wall surface (a) of a spindle 14 and are pressed there. Thus, the centering precision is improved because a center hole (b) of a medium 8 follows up uniformly the spindle 14 on a circle.
