Title: Image forming device
Inventor: MATSUOKA ISAO
IPC: G03G15/00
Filed: 1994-02-28
Abstract: PURPOSE:To restrain the change of rotating speed caused by small fluctuating torque to such an extent that image-forming is not hindered by normally giving comparatively large load torque to a photoreceptor. CONSTITUTION:An arm-like sliding member 106A whose moment of inertia is large is turnably supported at a part positioned inside the drum of an integrated driving shaft 103A driving a photoreceptor drum 10A. When the drum 10A is rotated by the driving of the driving shaft 103A in a state where a frictional material 107A attached to the tip of the sliding member 106A abuts on the inner peripheral surface of the drum, the sliding member 106A is retained at a fixed position by the moment of inertia so that the frictional material 107A normally applies the specified load torque to the drum 10A by the sliding thereof.

Abstract: PURPOSE:To stabilize the standard of judgement and make the inspection performed at high speed by a method wherein a reflected light obtained by scanning a plate to be inspected by a spot light is detected by a plurality of light-receiving units having specific opening parts and the outputs thereof are judged through comparison. CONSTITUTION:The spot beam 2 of a laser 14, for instance, is applied on the plate 1 to be inspected, thereby scanning is conducted perpendicularly to the moving direction of the plate 1 to be inspected, and the reflected light therefrom is imaged on a screen 8 through the intermediary of a lens 11. In the rear of the screen 8, the light-receiving units 6, 6' and 6'' having opening parts 6a, 6b, 6a', 6b' and 6a'' are arranged. The judgement of the surface of the plate is performed by comparing mutually the outputs of the light-receiving units 6, 6' and 6'' based on the distribution 4 of the reflected light which has projections 12 caused by scratches on the plate 1. By this method, the standard of the judgement is stabilized and the inspection can be made to be of high speed.

IPC: G01N27/04
Filed: 1994-02-01
Abstract: PURPOSE:To reduce the temperature dependency of a sensor element and to improve the gas selectivity of the element against organic gases, etc., by alternately applying positive and negative voltages across the element. CONSTITUTION:A sensor element is provided with an insulating substrate 1, a pair of electrodes 2a and 2b, a gas sensitive film 3, a heater 4, and lead wires 5. The film 3 is directly formed on the substrate 1 by sputtering or vacuum heating evaporation. Then, while positive and negative voltages are alternately applied across the electrodes 2a and 2b, the impedance variation of the element is detected as sensor signals. Since the polarity of the potential between the electrodes 2a and 2b is alternately switched, the influence of an electric field can be eliminated and stable and accurate output signals can be obtained. Since the influence of the frequency of the alternating voltage (polarity changing speed of the electric field) on the equilibrium gas adsorption varies depending upon the kind of gases, the frequency of the alternating voltage is adjusted to a gas to be detected when the gas is to be selectively detected.

Title: Magnetic fine particle and production thereof
Inventor: SEGAWA MASARU
IPC: C23C14/06
Filed: 1994-02-02
Abstract: PURPOSE:To develop a domain pattern with high resolution by setting the saturation magnetization at a specific level or below and setting the pressure of Ar gas within a specific range thereby suppressing the aggregation of magnetic fine particles. CONSTITUTION:Individual magnetic fine particle responses quite sensitively to the pole of a magnetic material and the field produced from a magnetic wall and adheres selectively to the pole. The fine particles collide each other frequently in an inert gas because of high degree of freedom thereof. A fine particle having saturation magnetization of 50emu/g or less exhibits low magnetic interaction to cause low aggregation upon collision. Even after selective adhesion to the pole and magnetization, the fine particles are not coupled in chain with other fine particles adhering subsequently to the pole nor aggregated because of low value of magnetization. The magnetic fine particles are produced by inert gas evaporation where the pressure of AR gas is set in the range of 0.15-0.7Torr. It is distinguished by a magnetization patterns having magnetic inversion length of 0.39mum(10MHz signal) and 0.24mum (16MHz signal).

IPC: E04F15/02
Filed: 1994-03-01
Abstract: PURPOSE:To enhance bactericidal and insecticidal functions by weaving as the weft needle thread of a tatami border a filament made of a high-density polyethylene with an antibacterial agent and a mothproofing agent added thereto. CONSTITUTION:A weft needle thread, a weft bobbin thread and a warp, all made of synthetic fibers, are woven into a tatami border. In this case, a functional monofilament, spun from a high-density polyethylene melted with an antibacterial agent and a mothproofing agent added thereto, is used as the weft bobbin thread. A chemical is blended in the weft needle thread which has a large degree of surface exposure, so as to effectively mildewproof and mothproof that side of the tatami border which comes into contact with human bodies. The effective components are kneaded so as to lower the speed at which they are released, thereby keeping effects over a long period. Therefore, a comfortable living environment on the tatami can be maintained and costs can be reduced.
