Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/65
Filed: 1987-12-19
Abstract: PURPOSE:To obtain a magnetic recording medium which is improved in C/N of a short wavelength region by disposing a fine particle coated layer on a high-polymer film, then providing a thin ferromagnetic metallic film consisting of curved fine columnar particle having >=0.85 packing rate thereon. CONSTITUTION:The fine particle coated layer 2 is disposed on the high-polymer film 1 and the thin ferromagnetic metallic film 3 consisting of the curved fine columnar particle having >=0.85 packing rate is disposed thereon. The microscopic deformation under high-speed sliding contact with a magnetic head is thereby decreased to a negligible level and the modulation noise is improved; in addition, the C/N is improved as well in contrast with the conventional media which result in the increased modulation noise with shorter wavelengths and are consequently degraded in the C/N while the fine ruggedness formed by the fine particle coated layer 2 contributes to a remarkable improvement in durability.

Title: Electrophotographic photoreceptor
Inventor: MASUDA SHUNICHI
IPC: G03G21/16
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To make only a photoreceptor replaceable and eliminate the necessity of partially increasing strength by composing a photoreceptor of a rotor part provided with a driving gear part for rotatory-driving the other part of a device body, and a drum-like electrophotographic photoreceptor part with one end fixedly fitted to the rotor. SOLUTION: A motor 24 for rotatory-driving a photoreceptor 2 is composed of a DC motor fitted to a base 25, and this motor 24 has a stator part 24A and a rotor part 24B. A shaft 24C of the rotor part 24B is rotatably supported on the stator part 24A by a bearing. The photoreceptor 2 is removably connected to the outer rotor part 24B of the motor 24. A driving gear 29 for rotatory-driving the other part of a recording device is formed at a part of the rotor part 24B, and this driving gear 29 transmits rotation to a paper feed roller and a register roller through a gear train 30. Only the photoreceptor 2 can thereby be replaced as a consumable component, and since a gear part is provided at the photoreceptor itself, there is no need to additionally heighten strength.

Title: Ink jet recording method, ink jet recorder used in the method, and ink jet recorded matter recorded by the method
Inventor: SHIKAME OSAMU
IPC: B42D15/00
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous diagnosis by recording information of gray scale, for example, with an image preservability decision ink at a specified location of an image other than the effective area so that deterioration of the image due to fading or discoloration of dye can be determined easily. SOLUTION: Information of gray scale, for example, is recorded with an image preservability decision ink having lower lightfastness and weatherability than a medical image recording ink at a specified location of an image other than the effective area. A preservability deciding section comprising a stocker 3, a printer 4 and a preservability deciding section decides the preservability using an optical density and color difference detector comprising a light emitting element, e.g. a halogen lamp or an LED, a CCD, a spectral sensor and a microcomputer. A decision is made that the preservability is not acceptable when the optical density(OD) fluctuates 10% or more from the original level. Decision accuracy can be enhanced by forming a patch of gray scale at an appropriate interval of maximum and minimum OD parts and making a decision at each density.

Title: Wheel chair
Inventor: KAMITE MASAYUKI
IPC: A61G5/02
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To allow a wheel chair to easily get over a step with the center of gravity thereof shifted to the rear part thereof by longitudinally moving a driving wheel frame to or from a seat frame following the operation of a forced operation mechanism to allow selection of the position of a running guide caster narrowed in distance to a driving wheel or that of the caster returned to the original point. SOLUTION: When an attending person or the like of a wheel chair 1 pulls a forced operation mechanism 12 to be fixed on a fixing metal fitting 13 for getting over a step, a parallel link member 11 turns centering around a link point with a seat frame 10A to narrow the distance between a running guide caster 3 and a driving wheel 1. As a result, while a seat 5 is maintained horizontally, a mounting part of the running guide caster 3 of the seat frame 10A is hoisted to let the running guide caster 3 float simultaneously with the shifting of the center of gravity of the wheel chair 1 to the rear part thereof 1. Therefore, as the wheel chair 1 advances toward a step, the wheel chair can get over the step immediately with the running guide caster 3. This allows the wheel chair 1 to get over the step simply and accurately.
