Abstract:
Disclosed is a loading unit for use in loading a bundle of objects to be conveyed, the loading unit being installed on a lifting member of a feeding device. The loading unit includes a first movable base on which a downstream side in a conveying direction of a bundle of objects to be conveyed is loaded, the first movable base being rotatable; and a second movable base on which an upstream side in the conveying direction of the bundle of objects is loaded, the second movable base being rotatable and disposed on a more upstream side in the conveying direction than the first movable base.
Abstract:
A sheet feeding device, which is included in an image forming apparatus and an image forming system, includes a sheet loader, an air drawing body, an attracting and conveying device, an air duct and a blocking device. The sheet loader is a device on which a bundle of sheets is loaded. The air drawing body is configured to generate suction air. The attracting and conveying device is configured to attract a sheet on top of the bundle of sheets by the suction air and convey the sheet. The air duct is configured to intake the suction air drawn by the air drawing body, to the attracting and conveying device. The blocking device is configured to block the suction air in the air duct.
Abstract:
A paper feeding apparatus includes: a sheet loading unit for loading a bundle of sheets; a separation unit that separates a topmost sheet of the bundle of sheets loaded on the sheet loading unit, from the bundle of sheets; a conveyance unit that conveys the separated topmost sheet; an end fence that is movable in a sheet conveyance direction, abuts trailing ends in the sheet conveyance direction, and positions the bundle of sheets in the sheet conveyance direction; and a pressing unit that is provided in such a manner as to protrude from the end fence, and is able to press the trailing ends in the sheet conveyance direction of at least an upper part of the bundle of sheets, wherein the pressing unit has different pressing forces at an upper and a lower portion thereof, and has the lower pressing force stronger than the upper pressing force.
Abstract:
A rotor includes a rotor core fixedly attached to a rotational shaft and having a plurality of hole portions arranged in the circumferential direction, a magnet inserted into a plurality of hole portions each, and a filling portion injected into the hole portion. The filling portion is injected into the hole portion from a gate facing a central part in the width direction of the magnet in the opening of the hole portion.
Abstract:
A sheet material conveying device includes: a sheet material housing unit; a sheet material conveying unit that conveys each sheet material to a predetermined conveyance target position; a separating/feeding unit that separates a sheet material from sheet materials in the sheet material housing unit and conveys the separated sheet material alone to the sheet material conveying unit; a multi-feed detecting unit that detects whether multi-feed occurs in which a plurality of sheet materials are fed from the separating/feeding unit to the sheet material conveying unit; and an internal sheet material detecting unit that detects presence of the sheet material in the sheet material conveying unit. The sheet material conveying device performs multi-feed failure detection control for detecting whether a failure occurs in the multi-feed detecting unit before notification of a detection result of the internal sheet material detecting unit.
Abstract:
Provided are N-acyl-β-lactam derivatives represented by the following general formula, from which a photoresist composition capable of controlling an acid diffusion length to be short is obtained; a polymer obtained by polymerizing the N-acyl-β-lactam derivative represented by the following general formula as one of starting materials; and a photoresist composition containing the polymer, where the structural variables are as defined herein.
Abstract:
A sheet conveying device includes: a separation sheet feeding mechanism having a paper feeding belt and a separation roller; and an adjustment mechanism that changes contact state of the paper feeding belt to the separation roller by changing relative position of the paper feeding belt and the separation roller, and changes and adjusts separation performance of the separation roller for the subsequent sheet, wherein the adjustment mechanism includes a cam follower member changing the relative position of the feeding belt and the separation roller, the cam member includes a first cam face and a second cam face which are formed at each rotation radius position in accordance with the rotation angle position, and are spaced apart in the rotation radius direction, and the cam follower member has a contact unit guided by the first cam face and the second cam face.
Abstract:
A feeding device includes a carrying roller to carry a top sheet of sheets in a conveying direction, a reverse roller to transfer subsequent sheets beneath the top sheet in a direction opposite to the conveying direction while being moved in the conveying direction with the top sheet, and an end fence to restrict rear end positions of the subsequent sheets. The end fence includes an upper contacting member to come into contact with an upper surface of the top sheet, and a restricting member extending from the upper contacting member along a rear end surface of the sheets to stop rear ends of the sheets in its entire width direction, the upper contacting member and the restricting member being arranged such that a width dimension of the end fence is changeable in the width direction, and the end fence being arranged above the top sheet.
Abstract:
Provided are 1) a production process for an acrylic ester derivative capable of being a raw material of a polymer for obtaining a photoresist composition capable of forming a photoresist film which is excellent in a reactivity to acid and a heat stability and is less swollen in developing and which has a refractive index of preferably 1.72 or more in 193 nm and can be patterned, 2) an acrylic ester derivative obtained by the above production process and 3) alcohol and ester which are synthetic intermediates for the above acrylic ester derivative.
