Publication number: 20100031576Abstract: A window regulator includes a carrier. The carrier includes a holding section and is capable slide along a guide rail with the holding section slidably contacting on the guide rail. The carrier supports a window panel. A brake mechanism is provided on the carrier. The brake mechanism prevents the window panel (the carrier) from self-weight drop by slidably contacting onto the guide rail by an urging force thereof. According to the window regulator, good down operations of the window panel can be maintained even if a slidably contacting portion(s) of the holding section that holds the guide rail becomes worn.Type: ApplicationFiled: August 5, 2009Publication date: February 11, 2010Applicant: MITSUI MINING AND SMELTING CO., LTD.Inventors: Kazuyuki Sasaki, Yosuke Kitamura, Yasunori Nakajima

Publication number: 20070045306Abstract: A fan motor is mounted on the upper wall of the casing. The lower surface of this upper wall is formed into an inclined surface in which inclination is formed from the front wall side of the casing toward a back wall across from the front wall. When the fan motor is driven, oil mist or moisture contained in the air are condensed into water droplets or oil droplets. These water droplets or oil droplets fall and flow to the inner wall surface of the upper wall of the casing along the inner peripheral wall of a vent hole. Then the water droplets or oil droplets flow along the profile line of a vent hole smoothly (without stopping) and roll down the side wall of the casing.Type: ApplicationFiled: July 19, 2006Publication date: March 1, 2007Applicant: FANUC LTDInventors: Kazuhiko Hirano, Kazuyuki Sasaki

Patent number: 6285778Abstract: The vehicle surroundings monitor detects the sizes and positions of obstacles, ditches and humans as well as the depths of the ditches to provide the driver with sufficient information to secure safety during driving. The pattern light projector receives an incoming laser beam and projects a light spot matrix in the form of a regular grating onto the monitored area. The camera photographs the light spot pattern on the monitored area and sends image signals to the data processor which processes the image signals to detect the presence of any obstacle, ditch or human. Based on the steering angle detected by the steering angle sensor, the path the car will take is predicted and a possible contact or collision of the car with the obstacle is detected beforehand. The buzzer, voice synthesizer and display device are used to alert the driver and indicate the presence of the obstacles, the possible contact with them and the location where the possible contact will occur.Type: GrantFiled: June 6, 1995Date of Patent: September 4, 2001Assignee: Yazaki CorporationInventors: Masato Nakajima, Junichi Yamaguchi, Hiroya Akita, Yoshihiro Tsuji, Kazuyuki Sasaki, Naoto Ishikawa

Patent number: 6246961Abstract: A collision alarm method and apparatus for vehicles in which, in order to detect and alarm of danger of collision, the time of possible collision is calculated by a danger judgement means from optical flow. In order for an image processing means to detect the optical flow, a horizontal or vertical noticeable edge is used, which edge is extracted from two images obtained at different times with an image photographing means. The collision alarm method and apparatus for vehicles detect danger of collision at high speed and gives a timely alarm so as to enable collision avoiding action to be securely taken.Type: GrantFiled: June 8, 1999Date of Patent: June 12, 2001Assignee: Yazaki CorporationInventors: Kazuyuki Sasaki, Naoto Ishikawa, Masato Nakajima, Hirosada Miyaoka

Patent number: 6049747Abstract: In a driver monitoring system, a pattern projecting device consisting of two fiber gratings stacked orthogonally which receive light from a light source projects a pattern of bright spots on a face of a driver. A image pick-up device picks up the pattern of bright spots to provide an image of the face. A data processing device processes the image, samples the driver's face to acquire three-dimensional position data at sampling points and processing the data thus acquired to provide inclinations of the face of the driver in vertical, horizontal and oblique directions. A decision device decides whether or not the driver is in a dangerous state in accordance with the inclinations of the face obtained. A warning device warns the driver against his dangerous state. The pattern light projecting device and pick-up device are integrated to each other and installed on a steering column on a vehicle.Type: GrantFiled: June 10, 1997Date of Patent: April 11, 2000Assignee: Yazaki CorporationInventors: Masato Nakajima, Kazuyuki Sasaki, Naoto Ishikawa
