Patent number: 6832895Abstract: A cooling fan acts as a light shield to block light from shining therethrough, and also provides good air circulation. An impeller, which is a key constituent component of the fan, is split into a front stage impeller and a rear stage impeller. The front stage impeller has front stage blades, and the rear stage impeller has rear stage blades. Each of the front stage blades overlaps with the adjacent blades of the rear stage blades so as to cover the gaps between the sides of the rear stage blades. With this arrangement, the incident light beams are blocked by the blades, and also the constituent components can be released easily from the dies after molding. Still further, the air circulating characteristic is not degraded in the light shield fan of the present invention.Type: GrantFiled: November 26, 2002Date of Patent: December 21, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Koji Yoshioka, Shoji Kawahara

Publication number: 20040071553Abstract: With a trend toward a higher intensity projection type liquid crystal display device to further increase brightness of a projection screen, rated input power of a light source lamp increases, which makes essential a fan apparatus for cooling the light source lamp, etc. Such a fan apparatus would require a light-shielding member which causes the number of parts to increase. The present invention provides a fan apparatus provided with a rotor section 410 that can be rotated/driven around a predetermined rotation axis and a propeller section 420 including propeller blades 421 to 428 and attached to the rotor section 410 arranged in such a way as to substantially shield light parallel to the rotation axis.Type: ApplicationFiled: December 4, 2003Publication date: April 15, 2004Inventors: Shoji Kawahara, Takehiro Okada, Makoto Hoshino, Koji Yoshioka

Patent number: 6692025Abstract: A tilt steering apparatus has a pivot fixed to, for example, a pair of fixed side plates of a vehicle body. The pivot is inserted through a connection hole provided in a steering column. At the time of tilt adjustment, the steering column is swung around the pivot. In either one of an inner peripheral surface of the connection hole and an outer peripheral surface of the pivot opposite thereto, a projection extending in a substantially circumferential or axial direction is formed in contact with the other peripheral surface. Consequently, the contact area between the pivot and the connection hole is reduced, thereby reducing friction therebetween. When the pivot is pressed into the connection hole, the projection is suitably crushed, so that fitting between the pivot and the connection hole is loosened, which is useful for the reduction in the friction therebetween.Type: GrantFiled: September 27, 2001Date of Patent: February 17, 2004Assignee: Koyo Seiko, Ltd.Inventors: Koji Yoshioka, Susumu Imagaki

Patent number: 6523432Abstract: A lower bracket for mounting a steering column to a vehicle body is formed as a single element that is fixed to the vehicle body by inserting a bolt with a collar therethrough. Upon application of an impact load, the lower bracket forces the bolt and collar into a path of a smaller width than the collar thereby plastically deforming an edge portion of the path for absorption of the impact energy.Type: GrantFiled: September 6, 2000Date of Patent: February 25, 2003Assignee: Koyo Seiko Co., Ltd.Inventors: Yoshitaka Yamamoto, Koji Yoshioka, Noboru Minamoto

Patent number: 6040814Abstract: An active-matrix LCD causes no cross-talk even if the capacitance between a given cell and adjacent data lines is large. The LCD has a liquid crystal panel which has data lines arranged in parallel with one another, scan lines arranged orthogonally to the data lines, and liquid crystal cells arranged at the intersections of the data and scan lines, respectively. Each of the cells has a cell electrode and a switching device that is arranged between and connected to the cell electrode and a corresponding one of the data lines. The conduction of the switching device is controlled in response to a scan pulse applied to a corresponding one of the scan lines. The LCD also has a data driver for applying data signals to the data lines, respectively, so that the data signals are written to corresponding ones of the cells, and a scan driver for applying the scan pulse sequentially to the scan lines.Type: GrantFiled: May 13, 1996Date of Patent: March 21, 2000Assignee: Fujitsu LimitedInventors: Hiroshi Murakami, Koji Yoshioka, Keizo Morita, Masafumi Itokazu, Ken-ichi Nakabayashi, Akira Yamamoto, Munehiro Haraguchi
