Patent number: 6518547Abstract: A substrate heat treatment apparatus irradiating a substrate such as a semiconductor wafer with light and performing heat treatment is provided. 19 lamps 82 are arranged on a plane in the form of a honeycomb to form a lamp group 81. The lamp group 81 has 6-fold rotation symmetry about a symmetry axis XR. A substrate W is rotated about a rotation axis XW in a plane parallel to that formed by the lamp group 81. The symmetry axis XR of the lamp group 81 and the rotation axis XW of the substrate W are displaced for relaxing peaks and bottoms of illuminance distribution on the substrate W resulting from regularity of arrangement of the lamp group 81. Consequently, fluctuation of radial illuminance distribution on the substrate W is reduced and improving uniformity is improved. When the uniformity of radial illuminance distribution on the substrate W is improved, temperature uniformity of the substrate W in heat treatment can be ensured.Type: GrantFiled: February 16, 2001Date of Patent: February 11, 2003Assignee: Dainippon Screen Mfg. Co., Ltd.Inventors: Mitsukazu Takahashi, Hideo Nishihara, Yoshio Ito

Publication number: 20010040067Abstract: On the outer periphery of a bearing 10 for supporting a worm 71 rotating interlocked with the rotation of a steering assist motor 6 inside the housing 8, elastic members 20 are provided to restrain the bearing 10 from moving in the radial direction thereof. The force for the restraint by the elastic members 20 is made different depending on the position in the peripheral direction thereof. A portion of the elastic member, wherein the force for restraining the movement of the bearing 10 in the radial direction is small, energizes the worm 71 to the meshing position of the worm 71 and a worm wheel 72. Another portion, wherein the force for restraining the movement is large, restrains the worm 71 from moving along the lead of the worm wheel 72. With this configuration, the elastic members 20 can reduce the amount of the backlash at the meshing portion of the worm 71 and the worm wheel 72, and can make the rotation torque applied to the meshing portion of the worm gears relatively small.Type: ApplicationFiled: May 10, 2001Publication date: November 15, 2001Applicant: KOYO SEIKO CO., LTD.Inventors: Tetsuya Murakami, Takeo Iino, Masanori Kobayashi, Akihiko Shiina, Yoshio Ito, Tatsuo Otsuka, Takayuki Todaka

Patent number: 6275604Abstract: A computer implemented method and an apparatus for generating exposure data of a layout pattern used to fabricate semiconductor integrated circuits. The layout pattern is first analyzed to determine if it can be modified to one or more predefined patterns without having to segment the layout pattern into rectangular patterns. The layout pattern is then modified to the one or more predefined patterns. The modified pattern is also analyzed to determine if it can be modified into segmental block patterns and if so, it is modified accordingly. Finally, exposure data is generated using the modified segmental block patterns.Type: GrantFiled: August 12, 1998Date of Patent: August 14, 2001Assignee: Fujitsu LimitedInventors: Masaaki Miyajima, Yoshio Ito

Patent number: 5941793Abstract: It is an object of the invention to provide a shift control apparatus which does not cause a vehicle driver to feel uncomfortable when shift control means resumes normal shift control using a predetermined shift pattern. Where return-to-normal determining means 105 determines that a condition or conditions under which the shift control means 102 resumes shift control using a MEDIUM MODE shift pattern is/are satisfied, return-to-normal permitting means 116 permits the shift control means 102 to resume the shift control using the MEDIUM MODE shift pattern when an output control member release determining means 108 determines that an accelerator pedal 58 has been released. In this arrangement, the driver does not feel uncomfortable even if the transmission is shifted up immediately after the shift control means 102 resumes the shift control using the MEDIUM MODE shift pattern.Type: GrantFiled: February 28, 1997Date of Patent: August 24, 1999Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yoshio Ito, Yasunari Nakamura, Takashi Ohta, Kazuyuki Shiiba, Kunihiro Iwatsuki, Tooru Matsubara

Patent number: 5769412Abstract: A first shaft 21 and a second shaft 31 parallel with each other are provided near an inlet 14 of a bill storage chamber 10. Taking-in runners 20 are disposed on the first shaft 21 and taking-in rollers 30 are disposed on the second shaft 31. The taking-in runners 20 and the taking-in rollers 30 differ in position in a direction in which the shafts extend. Further, the sum of the radius of each taking-in runner 20 and that of each taking-in roller 30 is larger than the spacing between the first shaft 21 and the second shaft 31. Thus, if a plurality of overlapped bills are caught in the space between the taking-in runners 20 and the taking-in rollers 30, they are bent in a wavy form and the intimate contact force between the bill is lowered significantly, causing the bills to be easily aligned.Type: GrantFiled: September 3, 1996Date of Patent: June 23, 1998Assignee: Kabushiki Kaisha Ace DenkenInventors: Takatoshi Takemoto, Yoshio Ito, Motohiro Sugawara
