Patent number: 5465827Abstract: A movable member supported for movement on a track has a pressure receptor portion which faces laterally outward. An accelerating device in a horizontally held particular track portion of the track, at the upstream side thereof, acts upon the pressure receptor portion to apply high speed transport force to the movable member. A decelerating device at the downstream side of the particular track portion acts upon the pressure receptor portion to decelerate the movable member. The accelerating device acts upon the pressure receptor portion at the downstream side of the particular track portion, whereby high speed transport force is applied to the movable member so that the movable member may be transported at high speed on the horizontally held particular track portion. The decelerating device acts upon the pressure receptor portion of the movable member being transported at high speed, whereupon the movable member is decelerated.Type: GrantFiled: January 19, 1995Date of Patent: November 14, 1995Assignee: Daifuku Co., Ltd.Inventors: Susumu Nakagawa, Nobuhiro Hayashi, Hiroshi Nakagawa

Patent number: 5466109Abstract: A carrying in-and-out device is provided with four posts which are disposed in a distributive arrangement. The provision of the four posts ensures sufficient strength of the device even if the posts are formed thin, and the distributive disposition of the posts minimizes the turbulence and swirls of clean air to be caused when the clean air collides with the posts. As a result, there is little agitation of dust particles inside a passage. The dust particles are carried along without being scattered, and thus, loads can be prevented from adhering to the dust particles. Dust particles produced in an upper frame are sucked by upper fans and then discharged into the posts. The dust particles on the posts are further sucked by lower fans to be discharged downward.Type: GrantFiled: September 16, 1994Date of Patent: November 14, 1995Assignee: Daifuku Co., Ltd.Inventor: Yukio Iizuka

Patent number: 5460257Abstract: A main conveyer structure 3 incorporates a controller 40 having function to control rotation of conveyer rollers 2. The controller 40 incorporates a plurality of I/O ports 42 for exchanging data signal with respective controllers 40 of conveyer units 1 adjoining in four directions. The I/O ports 42 stores the numbers registered for respective conveyer units 1 in the course of transmitting and receiving the registerable number to and from the controller 42, and then, based on the registered numbers stored in the I/O ports 42, the controller 40 prepares a table for designating direction of driving respective conveyer units 1. By referring to the prepared table designating registered numbers of the start conveyer unit 1 and the destination conveyer unit 1, the controller 40 correctly determines the direction of driving the rollers 2 based on data for conveyance yielded from the table.Type: GrantFiled: March 29, 1994Date of Patent: October 24, 1995Assignee: Daifuku Co., Ltd.Inventor: Yutaka Yoshida

Patent number: 5460285Abstract: A pressure relief venting lid for sealing an opening and providing pressure regulation of a container. The lid has a support plate attached by four angularly spaced spring assemblies to a port cover for sealing a filler opening in a manway cover for the container. The support plate overlies the port cover for fixedly supporting the spring assemblies and cover while protecting the springs and cover from impact or shock. The spring assemblies are disposed between the support plate and port cover for sealing the cover against the opening and allowing the cover to unseat from the opening to regulate the pressure within the container. The spring assemblies are offset equal distances from the center of the port cover to minimize bending moments that the cover may be subjected to. The generally circular port cover has a convex dished portion for strengthening the port cover to maintain the seal with the opening while under load.Type: GrantFiled: July 6, 1993Date of Patent: October 24, 1995Assignee: Clawson Tank CompanyInventor: Robert A.

Patent number: 5458762Abstract: The present invention relates to an electrolyzer for treating an object liquid. A cylindrical anode plate is formed as an outer wall of said electrolyzer and a cylindrical cathode plate is coaxially arranged at a position close to an inner surface of said anode plate. An ion exchange membrane is coaxially arranged between both electrodes to form an isolating chamber for a selective electrophoretic separation and removal and a concentration. A liquid, which has been subjected to an aimed treatment in said isolating chamber, is uniformly flown out from a whole circumference through a circumferential passage provided in an upper portion of an electrode portion. Thus, anions, which have acted upon metal cations, are dissociated in said isolating chamber to selectively separate merely cations.Type: GrantFiled: February 24, 1994Date of Patent: October 17, 1995Assignee: Unitika Ltd.Inventors: Tadaya Ishibashi, Masanori Sasaki, Hideto Obara, Hiroshi Kano

Patent number: 5452701Abstract: An electrically operated fuel pump for automotive vehicles which utilizes a turbine pump rotor operating in an annular pumping channel having circumferentially spaced inlet and outlet ports. The pumping channel has opposed sides with a circumferential array of radially curved grooves axially opposed to the periphery of the impeller and extending radially inwardly from the impeller vanes. The pump has a main outlet leading to the engine to be supplied with fuel. A secondary outlet leads to a fuel jet positioned to direct fuel into a venturi passage to draw fuel from a pump inlet and discharge it into a reservoir in a main fuel tank, the pump being located in the reservoir. A biased valve in the secondary outlet opens when the pump outlet pressure reaches a predetermined pressure to insure adequate fuel flow to the engine upon cold start conditions before fuel is drawn by the jet and venturi and delivered to the reservoir.Type: GrantFiled: May 23, 1994Date of Patent: September 26, 1995Assignee: Walbro CorporationInventor: Charles H. Tuckey

Patent number: 5450929Abstract: A maintenance elevator 40 is employed in the case of an emergency situation such as a failure of the carriage 16 or in carrying out regular maintenance and checkup operations. An operator can get on the maintenance elevator 40 brought to a stop at its lowermost position. The maintenance elevator 40 is moved upward along a post 12 and is brought to a stop at any position in which, for example, a gangway 57 formed integrally with the elevator 40 is opposed to the carriage 16. Movement of the operator between the maintenance elevator 40 and the carriage 16 can be done by utilizing the gangway 57. Transfer from the maintenance elevator to the carriage and vice versa can be always made in an easy and safe manner by using the gangway. Provision of all the gangways at the maintenance elevator side realizes weight reduction at the carriage side, good energy saving, and cost reduction.Type: GrantFiled: October 19, 1993Date of Patent: September 19, 1995Assignee: Daifuku Co., Ltd.Inventors: Kazuyoshi Ohgita, Tomokatsu Sugawara
