Patent number: 10495114Abstract: A blower fan includes a plurality of blades radially extending from a boss provided at a rotary center and spaced apart from each other in the rotational direction, and a ring portion connecting outer peripheral ends of the blades in a ring shape. A radially outer end part at an end on an air-flow upstream side of the ring portion is positioned outward in a radial direction of a rotary shaft in the blower fan, as toward the air-flow upstream side. Thus, the blower can prevent the backflow air from being swirled, thereby reducing noise.Type: GrantFiled: February 20, 2015Date of Patent: December 3, 2019Assignee: DENSO CORPORATIONInventors: Toshikatsu Kondou, Youhei Kamiya, Masaru Kamiya, Takeshi Miyamoto, Masashi Matsukawa, Isao Kondoh, Takashi Ito, Kazuhiro Takeuchi

Patent number: 10309422Abstract: A blower fan includes a plurality of blades radially extending from a boss provided at the rotary center and spaced apart from each other in the rotational direction, and a ring portion connecting outer peripheral ends of the blades in a ring shape. An inner peripheral wall surface of an end part on an air-flow downstream side of a cylindrical portion is disposed on the outside in a radial direction of the rotary shaft in the blower fan, with respect to an end part on the air-flow downstream side of the ring portion. The end part on the air-flow downstream side of the cylindrical portion is positioned outward in the radial direction of the rotary shaft, as toward the air-flow downstream side. Thus, the blower can prevent the backflow air from being swirled, thereby reducing noise.Type: GrantFiled: February 20, 2015Date of Patent: June 4, 2019Assignee: DENSO CORPORATIONInventors: Toshikatsu Kondou, Masashi Matsukawa, Youhei Kamiya, Masaru Kamiya, Takeshi Miyamoto, Isao Kondoh, Takashi Ito, Kazuhiro Takeuchi

Patent number: 9768660Abstract: An air purge system includes an electric motor having an air purge device which supplies air to a space around the outer peripheral surface of an output shaft, an information acquisition unit which acquires operation information of the electric motor, and an air control unit, which controls the amount of air supplied from the air purge device in response to the acquired operation information. The air control unit increases the amount of the air supplied from the air purge device when the information acquisition unit acquires deceleration operation information of the electric motor.Type: GrantFiled: June 18, 2015Date of Patent: September 19, 2017Assignee: FANUC CORPORATIONInventor: Youhei Kamiya

Publication number: 20170261033Abstract: A spindle-bearing protecting device is provided that captures an indication of failure of the spindle bearings of a machine tool and can prolong the time until the main bearing is scorched. A spindle-bearing protecting device for protecting a bearing that supports a spindle to be rotatable, includes: a rotating part provided more to an outer side in an axial direction than the bearing, and having a rotor blade that rotates along with the spindle; a supply part that supplies coolant or lubricant to between the rotor blade and the bearing; a detection unit that detects abnormality of the bearing; and a control unit that controls a supply of coolant or lubricant by way of the supply part and the revolution speed of the spindle, in a case of the detection unit detecting abnormality of the bearing.Type: ApplicationFiled: March 1, 2017Publication date: September 14, 2017Inventor: Youhei KAMIYA
