Patent number: 7913820Abstract: A control system for elevators controls the operations of a plurality of elevator apparatuses. The elevator apparatuses have cars and elevator doorways provided at each landing floor. The control system for the elevators is equipped with a landing call registration device, a landing call automatic registration portion, a response selection portion, a passenger traveling time period calculation portion, and an opening/closing control portion. The landing call registration device is provided at the landing floor to be operable at the landing floor. The landing call automatic registration portion sets as a car call floor the landing floor whose landing call registration device is operated, and makes a car call registration for stopping one of the cars at the car call floor.Type: GrantFiled: December 7, 2005Date of Patent: March 29, 2011Assignee: Mitsubishi Electric CorporationInventor: Susumu Sakurai

Patent number: 7163871Abstract: A manufacturing method of a semiconductor device having a trench is provided to form, at a corner portion of the trench, an oxide film which is greater in thickness and smaller in stress than at other portions. When the trench formed in the semiconductor substrate is oxidized, it is oxidized in an oxygen environment containing dichloroethylene at a predetermined weight percent to allow the formation of an oxide film having a greater thickness at the corner portion of the trench than thickness at other portions, whereby the semiconductor device improving dielectric breakdown characteristics can be obtained.Type: GrantFiled: January 26, 2004Date of Patent: January 16, 2007Assignee: Elpida Memory, Inc.Inventors: Taishi Kubota, Yoshihiro Kitamura, Takuo Ohashi, Susumu Sakurai, Takayuki Kanda, Shinichi Horibe
