Patent number: 8299410Abstract: 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: GrantFiled: December 28, 2010Date of Patent: October 30, 2012Assignee: Fanuc LtdInventors: Kazuhiko Hirano, Kazuyuki Sasaki

Patent number: 8215060Abstract: 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: GrantFiled: August 5, 2009Date of Patent: July 10, 2012Assignee: Mitsui Mining and Smelting Co., Ltd.Inventors: Kazuyuki Sasaki, Yosuke Kitamura, Yasunori Nakajima
