Patent number: 9080859Abstract: A housing including a base and cover has an open space that is open to the atmosphere and a closed space that is closed to the atmosphere. The open space contains a laser having a low operating temperature. The closed space contains a heat generating element and the like, which have higher operating temperatures than the laser. The heat generating element is in close contact with the base, which also serves as a heatsink, so that the heat generating element is cooled. Most parts of a motor, which is a heat generating member, are disposed in the closed space. A fan is diagonally disposed with respect to side surfaces of the heat generating element, which has a rectangular shape and flat side surfaces, so as to efficiently blow air toward the heat generating element disposed in the closed space.Type: GrantFiled: September 2, 2010Date of Patent: July 14, 2015Assignee: KABUSHIKI KAISHA YASKAWA DENKIInventors: Mikio Oshima, Mitsuhiro Matsuzaki, Hiroyuki Maezawa

Patent number: 8384251Abstract: A linear and curvilinear motor system includes: linear and curvilinear guiding devices movably guiding and respectively supporting right and left of a slider, each having a guide rail configured by linear tracks and a circular arc track and slider blocks; a motor unit having a stator with a stator linear section and a stator circular arc section and a mover with a linear section and provided for the slider and away from the stator with a gap interposed therebetween; and an encoder head and a hole sensor detecting positions of the linear tracks and the circular arc track. When a magnetic pole pitch of the linear section of the stator is a distance ?m and a magnetic pole pitch of the circular arc section of the stator is an angle ?m, a radius r of the circular arc track at the position detection point is defined as r=?m/?m.Type: GrantFiled: August 11, 2010Date of Patent: February 26, 2013Assignee: Kabushiki Kaisha DenkiInventors: Toru Shikayama, Mikio Oshima, Kenichi Sadakane, Shogo Makino

Patent number: 6195141Abstract: A hand-held control device comprises a casing (1) having a plurality of operating switches (21) and a cut hole (3) in front face thereof, a transparent window (5) fitted in the cut hole (3) of the casing (1), a printed circuit board (6) accommodated in the casing (1) and connected to the operating switches (21), a crystal liquid display plate (7) disposed near the window (5) of the casing (1) and connected to the printed circuit board (6) through a connector (8), the crystal liquid display plate (7) being fixed with a mounting member (10) so as to the connector (8) is sandwiched between the mounting member (10) and the printed circuit board (6), and an upper cover (17) and a lower cover (14) for holding the printed circuit board (6) through the buffer member (10). Accordingly, even when an impact is applied onto the casing (1), the liquid crystal display plate (7) is less affected thereby, and therefore the contents of display can be surely displayed on the liquid crystal display plate (7).Type: GrantFiled: September 18, 1998Date of Patent: February 27, 2001Assignee: Kabushiki Kaisha Yaskawa DenkiInventors: Takayuki Kawano, Masafumi Ushijima, Mikio Oshima

Patent number: 5665945Abstract: A deadman switch (4) comprises a pressing plate (5), a shaft (7) provided at the pressing plate (5), a dog plate (6) fitted over the shaft (7), a plurality of bosses (34), a spacer (9) fitted over the shaft (7), a spring (8) provided at the shaft outer circumferential portion, and three-point type limit switches (41), (42) attached on a back plate (3) and such that when dogs (41a), (42a) are engaged with the dog plate (6) so that the limit switches are in free state, they are turned OFF, when the dog plate (6) slightly pushes the dogs (41a), (42a), the limit switches are turned ON, and when the dog plate (6) comes into contact with the spacer (9) to further deeply push the dogs (41a), (42a) against spring force of the spring (8), the limit switches are turned OFF. Since this portable controller is securely turned OFF even if operator tightly grips the portable controller in the panic state based on runaway, etc. of robot, an extremely safety portable controller for robot of the fail-safe type can be provided.Type: GrantFiled: May 10, 1996Date of Patent: September 9, 1997Assignee: Kabushiki Kaisha Yaskawa DenkiInventor: Mikio Oshima
