Patent number: 7677787Abstract: A mixing degree adjusting device comprises a pair of spacer members arranged at a position sandwiching both round sectional portions of a pair of screws from both sides in the aligning direction of the pair of screws, and a pair of drawing members arranged as a position sandwiching both the round sectional portions from both sides in the orthogonal direction that is orthogonal to the aligning direction. The spacer members are movable between an adjusting position opposing to the round sectional portions, and a retracting position, when the screws are extracted from the barrel, for retracting to the outside until the passage of the screws is accepted. Opposing portions opposing to the round sectional portions at the time of moving to the adjusting position are formed in a substantially linear shape extending in parallel with the orthogonal direction seen from the axial direction of the screws.Type: GrantFiled: June 6, 2006Date of Patent: March 16, 2010Assignee: Kobe Steel, Ltd.Inventors: Yasuaki Yamane, Shin Hotani, Yoshinori Kuroda, Koichi Miyake, Katsunori Takahashi, Taiji Orimo

Patent number: 7644641Abstract: A rotor and a seat mounted on a first shell is disposed between an annular first shell and an annular second shell both constituting a damper case, thereby forming a rotary damper device. A damper lever on which the rotor is mounted is hooked on a fixing pin fixed to a body. Viscous fluid such as highly viscous oil is charged into a damper chamber formed between the rotor and the seat, and a viscous resistance is applied to the rotor and the seat. In a state in which a rotation center of the rotary damper device is deviated from a rotation center of the shaft which is rotated by the operating lever, the damper case is fixed to a flange portion of the shaft, the rotor and the seat are allowed to rotate relatively to each other by an inclining operation of the operating lever, and a resistance force from the rotary damper device is applied to the operating lever.Type: GrantFiled: September 22, 2004Date of Patent: January 12, 2010Assignee: Komatsu Ltd.Inventors: Masayoshi Mototani, Shuuji Hori, Daisuke Kozuka, Yasuhiro Sato, Koichi Miyake

Patent number: 5831389Abstract: A method and apparatus for controlling an au room lamp are provided, in which the room lamp is lit up when the ignition key is extracted from the ignition switch with an automotive door being closed, to thereby provide convenience for the driver and the passengers to get out of a car. A control unit (1) detects the on/off states of the ignition switch (2), a door switch (3) and an ignition key insertion/extraction detecting switch (4). If it is judged that the ignition key is extracted from the ignition switch with the door closed, the control unit turns on the room lamp (5) at a second luminance which is lower than a first luminance provided when the room lamp is on with the door being open, keeps the luminance of the room lamp for a predetermined time, and then turns off the room lamp.Type: GrantFiled: November 22, 1996Date of Patent: November 3, 1998Assignees: Mitsubishi Jidosha Kogyo Kabushiki Kaisha, Mitsubishi Jidosha Engineering Kabushiki KaishaInventors: Naoki Kawashima, Koichi Miyake, Yoshihiro Murase, Eri Nishikawa, Tamotsu Kurachi
