Patent number: 6764650Abstract: A rack transportation assembly having a projecting member projecting forward is fixed onto a floor by a plurality of adjusters so that its rack transportation surface is brought to a desired level. The projecting member has a first reference surface facing upward. A treatment unit structure having a rack transferring area has a second reference surface in its lower surface. The treatment unit structure is pushed toward the rack transportation assembly under a condition that the second reference surface is lifted upward using height-adjustable casters so as to not become higher than the first reference surface. Then, the treatment unit structure is lowered so that the second reference surface is mounted onto the first reference surface, and a height in the front side of the treatment unit structure is adjusted using the plurality of adjusters.Type: GrantFiled: August 15, 2001Date of Patent: July 20, 2004Assignee: Hitachi, Ltd.Inventors: Katsushi Takahashi, Hitoshi Tokieda, Toshiyuki Ikeda, Susumu Kai

Patent number: 6290907Abstract: A sample handling system comprising: a transportation line including a combination of plural partitive line units; and a plurality of handling units, wherein each of the plural partitive line units and each of the plurality of handling units form a pair, and each handling unit is installed removably from its corresponding partitive line unit. Each handling unit transmits inoperative information to the transportation line when it becomes inoperative. The transportation line transmits this inoperative information to the central controller. The central controller monitors handling units at which the sample rack can stop over. The sample rack avoids stopover at the inoperative handling unit, but is allowed to advance to the subsequent handling unit passing through the partitive line unit which makes a pair with the inoperative handling unit.Type: GrantFiled: September 10, 1998Date of Patent: September 18, 2001Assignee: Hitachi, Ltd.Inventors: Katsushi Takahashi, Mikio Komata, Toshiyuki Ikeda

Publication number: 20010013440Abstract: An all-terrain vehicle has a selectively engageable four wheel drive system. The system has dedicated rear wheel drive and selectively engageable front wheel drive. The front wheel drive is engaged within the differential housing. A differential input shaft extends into the differential housing. A stub shaft is journaled for rotation within the housing. A sleeve slides relative to the two shafts and couples the two through a coupling configuration. The coupling configuration results from the externally splined ends of the two shafts and the internally splined surface of the sleeve. The positioning of the sleeve is controlled by a shift fork. The shift fork is moved by an actuator in response to a signal produced by a control unit. A switch allows an operator to instruct the control unit when to engage and disengage the front wheel drive system.Type: ApplicationFiled: March 17, 1999Publication date: August 16, 2001Inventors: KAZUHIKO IZUMI, KATSUSHI TAKAHASHI
