Title: Conveyer device for furnace
Inventor: TANIGUCHI MASAHIRO
IPC: H05K3/34
Filed: 1987-12-25
Abstract: PURPOSE:To reduce the energy necessary for maintaining the temperature of the inside of a heating furnace and to make it possible to convey an article to be heated with low vibration by rotatably arranging at least two round rods each formed in the outer peripheral surface thereof with a spiral groove, in parallel with each other. CONSTITUTION:Two pairs of round rods (7 and 9), (8 and 10) formed therein with righthand threads and lefthand threads are rotated about their axes, in directions opposite to each other, so as to advance the right and left threads formed therein. Due to the advance of the threads in opposite directions, a print substrate clamped at both ends between the pairs of round rods (7 and 9), (8 and 10) is conveyed within a heating surface. With the use of the threaded round rods 7 through 10, it is possible to eliminate such a phenomenon that a large amount of heat is continuously dissipated into a room temperature atmosphere in the vicinity of the input and output ports of the surface, and so forth. Accordingly, it is possible to reduce the energy necessary for maintaining the temperature of the furnace. Further, since the print substrate slips on the threaded round rods 7 through 10, it is possible to reduce vibration during conveyance.

Title: Image forming device
Inventor: TSUKAMURA SHINICHI
IPC: G03G21/10
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To eliminate foreign matters as much as possible, to prevent image defect and to use a cleaning blade and a photoreceptor over a long term by adjusting so that abutting load between the photoreceptor and the cleaning blade may be smaller than load in the case of removing toner and reversely rotating the photoreceptor. SOLUTION: When image forming is completed, the photoreceptor drum 2 stands still and the rotation of a cam drive motor is stopped in a range where the blade 18 and the drum 2 is maintained in contact. At such a time, the blade 18 press-contacts the drum 2, and the abutting load between the drum 2 and the blade 18 is adjusted smaller than cleaning load for removing the toner. Then, the drum 2 is reversely rotated. Since the reverse rotation is reverse to a normal rotating direction, the foreign matter such as paper powder between the blade 18 and the drum 2 is moved toward a separation pawl in a state where it still adheres to the surface of the drum 2, and then removed from a part between them.

Title: Optical communication device
Inventor: INADA YORIFUMI
IPC: H04B10/25
Filed: 1987-12-29
Abstract: PURPOSE:To widen the frequency band of a transmission signal and to increase communicatable distance by selecting the numerical aperture at which the light emitted from a light source is projected to an optical fiber smaller than the incident numerical aperture intrinsic to the optical fiber. CONSTITUTION:Laser light 13 is transmitted as the transmission signal in the core 12a of the optical fiber 12 of a step index type via a lens 14. The numerical aperture of the luminous flux entering the optical fiber 12 is set smaller than the numerical aperture intrinsic to the optical fiber 12 by selecting the distance l2 between the incident end face 15 of the optical fiber 12 and the lens 14 at the distance larger than the distance l1 between a semiconductor laser 11 and the lens 14 in this case. The number of reflections of the light progressing zigzag while reflecting in the core 12a of the optical fiber 12 is, therefore, decreased and the distortion of the incident waveform generated by a difference in the optical route in the optical fiber 12 is suppressed. The communicatable distance is thereby increased and the frequency band of the transmission signal is widened as well.

Title: Ball screw
Inventor: SHIBATA YASUSHI
IPC: F16H25/22
Filed: 1990-11-28
Abstract: PURPOSE:To improve the sevice life of a ball screw for a ceramic ball to the same level as that of a ball screw for a steel ball by setting the ratio of radius of curvature on inside/outside orbital planes and radius of the ceramic ball smaller than that in the case of using the steel ball. CONSTITUTION:According to Hertz's elastic contact theory, in the case spherical surfaces are brought into contact with each other, when a load P and equivalent radius (p) are kept constant, diameter (d) of the contact surface becomes a function for elastic coefficient E and Poisson's ratio (v). Accordingly, under the same load P and equivalent radius (p), the contact area of a ceramic ball 3 and orbital planes 1a and 2a becomes smaller than that in the case of using a steel ball, and to that extent, high pressure compressive stress is acted on the contact surface. Then, by setting the ratio of radius of curvature on inside/ outside orbital planes 1a and 2a and radius of the ceramic ball 3 smaller than that in the case of using the steel ball, the contact area of the ceramic ball 3 and the orbital planes 1a and 2a is brought close to the contact area of the steel ball and the orbital planes, and thereby, stress on the contact surface can be reduced substantially to the same level as that in the case of using the steel ball.
