Patent number: 8246806Abstract: An electrophoresis apparatus includes a multi-capillary array having a liquid or solid disposed between the capillaries of the array. The liquid or solid exhibits a refractive index higher than that of air and less than that of water and reduces the amount of laser beams scattered by the capillaries. Also provided are methods of adjusting refracted and reflected excitation light beams passing through capillaries of a multi-capillary array, to reduce loss of intensity of the laser beams and increase irradiation of respective samples disposed in the capillaries.Type: GrantFiled: March 6, 2007Date of Patent: August 21, 2012Assignees: Applera Corporation, Hitachi, Ltd.Inventors: Ryoji Inaba, Tomohiro Shoji, Shozo Kasai, Masaya Kojima, Yasushi Shimizu, Seiichi Ugai, Eric S.

Patent number: 5393210Abstract: A motor-driven vertical type injection molding apparatus with stable screw back pressure is provided with a simple structure. A plurality of guide shafts extending in the perpendicular direction are integrally provided in a lower base of an injection unit. A screw holding member is supported on the plurality of guide shafts to be movable in the perpendicular direction. The screw holding member is moved in the perpendicular direction by an injection motor through a ball screw mechanism. A screw extension shaft is integrally connected to the upper end of a screw. The screw extension shaft is supported on the screw holding member to be movable in the axial direction and rotatable. The screw extension shaft and screw are rotated by a measuring motor. In a measuring step, the dead weight of the screw holding member automatically resists the reactive force (screw back pressure) of a molten resin at a screw tip end portion.Type: GrantFiled: July 5, 1994Date of Patent: February 28, 1995Assignee: Canon Kabushiki KaishaInventors: Shozo Kasai, Yozo Tohbo, Norio Nikaido, Hirofumi Sugawara

Patent number: 5332382Abstract: A screw holding member in which a screw is rotatably provided is guided in a vertical direction by two guide shafts. A ball screw is integrally provided on an upper part of the screw holding member through a load cell. A ball nut screwed to the ball screw is provided internally in an upper base through bearings. A second toothed pulley is fixed to the upper part of the ball nut. The ball nut is rotated by an injection motor through the second toothed pulley. The ball screw and the screw 44 are vertically driven by rotation of the ball nut. The second toothed pulley is formed with a through-hole into which the ball screw is loosely fitted, whereby the ball screw does not protrude from the second toothed pulley even when the ball screw rises.Type: GrantFiled: September 28, 1992Date of Patent: July 26, 1994Assignee: Canon Kabushiki KaishaInventors: Shozo Kasai, Yozo Tohbo, Norio Nikaido, Hirofumi Sugawara
