Publication number: 20140331505Abstract: A wind shielding portion is provided in a front side of an exhaust port for cooling air from a motor such that it crosses over a lateral width with respect to a cutting direction. The cooling air which is blown to the wind shielding portion is effectively blown through a ventilation portion having a small ventilating resistance force and towards a marking line guide. Even when the cutting device main body is set at an incline, the cooling air is blown to the wind shielding portion, and is effectively blown through the ventilation portion to the marking line guide.Type: ApplicationFiled: April 23, 2014Publication date: November 13, 2014Inventors: Sho KUME, Kenji ABE

Publication number: 20140331506Abstract: A jigsaw includes a motor, a rod having a blade attached thereto, a power transmission portion that converts rotation transmitted from the motor to vertical movement of the rod to vertically move the blade, and a counterweight that moves vertically in a direction of the vertical movement of the rod outside a range of the vertical, movement of the rod and the blade. At least a part of the counterweight is disposed so as to cross an extended line of a trajectory of the vertical movement of the rod.

Publication number: 20140167491Abstract: When removing a wheel cover from a wheel, force in an inner peripheral direction is applied to one end portion of an engaging member. The engaging member pivots (including elastically deforms) about the other end portion, such that an engaging protruding portion pivots and comes away from an engagable protruding portion. As a result, a center attaching portion is able to be removed from an ornament receiving hole, thus enabling the wheel cover to be removed from the wheel.Type: ApplicationFiled: June 21, 2012Publication date: June 19, 2014Applicants: PLAMAC CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuta Karashima, Kenji Abe, Masatsugu Sasagawa, Toshiyuki Tetsuda, Satoru Tsurubuchi, Tomoaki Kume, Yasuo Noji, Yasuhiro Kuraoka

Patent number: 8708113Abstract: A brake system includes a pad having a frictional surface, and a disc having a frictional surface sliding on the frictional surface. The frictional surface includes hard particles supported elastically and a plurality of protrusions arranged along a direction in which the frictional surface slides on the frictional surface, and when the frictional surface slides on the frictional surface, hard particles abut respective protrusions continuously while being displaced in the direction perpendicular to the frictional surface. Thus, wear resistance can be improved Since only the vicinities of the peaks of the hard particles and the vicinities of the peaks of the protrusions abut, the hard particles do not follow irregularities of the frictional surface, and thereby the hard particles and the protrusions repeat point contact. Thus, since the distance between the hard particles and the protrusions is stabilized and the adhesion frictional force is stabilized, a stable frictional force can be obtained.Type: GrantFiled: June 15, 2009Date of Patent: April 29, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kenji Abe, Hiroshi Isono, Yoshitomo Denou

Patent number: 8648484Abstract: Power generation efficiency is improved with a simple configuration. A braking device is provided with a brake rotor which rotates on a central axis, and friction portions which are in frictional contact with the brake rotor. A coil is wound around the outer peripheral portion of the brake rotor. A friction portion has the north pole of a magnet, and a friction portion has the south pole of a magnet. The braking device generates electricity by using an electromagnetic induction phenomenon and an electrostatic phenomenon that are caused by the interaction between the outer peripheral portion and the friction portion, for example, at the time of braking. As a result, the configuration can be simplified and the amount of power generation is not likely to be limited by a motor capability because there is very little need to use the motor as a generator.Type: GrantFiled: August 11, 2009Date of Patent: February 11, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kenji Abe, Hiroshi Isono, Yoshitomo Denou

Patent number: 8561763Abstract: A brake device includes a pad 100a having a friction surface 101 and a disk 200a having a friction surface 201 sliding on the friction surface 101. The friction surface 101 includes hard particles 102 that are elastically supported in a y direction perpendicular to the friction surface 201. The friction surface 201 includes a plurality of convex portions 202 that is disposed in a direction where the friction surface 201 slides on the friction surface 101.
