Patent number: 7186632Abstract: In a method for manufacturing a semiconductor device having a laminated gate electrode, a phosphorus-doped polysilicon is formed on a gate oxide film. A high-melting metal or a compound of a high-melting metal and silicon is formed on the polysilicon. Phosphorus is doped into the polysilicon so that a concentration of the phosphorus in the polysilicon at an interface between the polysilicon and the gate oxide film is 2×1020(1/cm3) or less. Then, thermal oxidation is carried out in a wet-hydrogen atmosphere containing water vapor.Type: GrantFiled: March 24, 2003Date of Patent: March 6, 2007Assignee: Elpida Memory, Inc.Inventors: Kazuo Ogawa, Kiyonori Ohyu, Kensuke Okonogi, Toshihiro Imamura, Keiichi Watanabe, Hiroyuki Ohta

Patent number: 6647667Abstract: The present invention relates to a trim or a seal member such as an opening trim weather strip. The trim or a trim body in the seal member has a holding lip portion and modified holding lip portions. And the holding lip portion and modified holding lip portions have head portions. The head portions are made to bulge out toward a bottom wall portion at the tip ends of modified holding lip portions of the trim or the trim body of trim portion. The modified holding lip portions are formed so that projecting lengths of the head portions from the end surfaces of tip end portions of the modified holding lip portions, and the thicknesses of the head portions increase in inverse proportion to lip projecting lengths of the modified holding lip portions from an inner surface of an interior side wall portion. Alternatively, a slope inclined with respect to an extension plane of an opening-portion-side surface of a base end portion is formed at tip ends of the modified holding lip portions.Type: GrantFiled: March 9, 2001Date of Patent: November 18, 2003Assignee: Toyoda Gosei Co., Ltd.Inventors: Kiminori Mine, Kazuo Ogawa, Keizo Hayashi

Patent number: 6019495Abstract: The presence or absence of any step-out of an actuator which is used to adjust a damping factor is made always detectable without additional provision of any special sensor such as a position encoder. Based on an equation of motion of a suspension, an estimated acceleration Gp derived from a detected vehicle height Sh and its differential Vr, and an actual acceleration Sg detected by an acceleration sensor, a deviation .DELTA.G is derived and compared against a threshold A. If the magnitude of the deviation is high, the occurrence of the step-out is declared after a given time interval T.sub.0. Upon detecting the occurrence of the step-out, the actuator position is returned to its home position, and the value in the position register is initialized. A skyhook control of the suspension is performed.Type: GrantFiled: June 14, 1994Date of Patent: February 1, 2000Assignees: Aisin Seiki Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Naoki Yamada, Satoru Onozawa, Shigetaka Isogai, Kazuo Ogawa

Patent number: 5701245Abstract: A suspension control system of the present invention varies a damping force according to a velocity ratio of a mass-body velocity to a relative velocity, while ensuring both a comfortable drive and stable cruising. In the suspension control system, a CPU calculates a mass-body velocity Zd and a relative velocity Yd based on detection signals from sensors and determines a velocity ratio Zd/Yd (steps S110 and S120). A small skyhook damping coefficient is set for a small vehicle speed V to reduce a damping force according to the velocity ratio Zd/Yd (step S130). In the process of varying the damping force, a stepping motor used for the variation in damping force is driven at a low driving frequency for a small vehicle speed V (step S180).Type: GrantFiled: October 6, 1995Date of Patent: December 23, 1997Assignee: Toyota Jidosha Jabushiki KaishaInventors: Kazuo Ogawa, Takaaki Enomoto, Masato Kawai, Minoru Kato, Kunihito Sato
