Patent number: 7268457Abstract: The present invention relates to an insulator to be disposed in an armature core having a plurality of radially-formed salient poles. The insulator comprises a winding aligning portion having an approximately V shape (forming an angle of 60 degrees) and getting narrower from an outer side to an inner side in a radial direction of the armature core approximately at the middle between the salient poles to position a winding disposed at a first layer which is a most inner side in the radial direction of the armature core approximately at a middle between the salient poles. By this structure, it is possible to align the windings on the second layer and beyond, thereby preventing a dig-in and the like of the windings and hence preventing faulty insulation between the windings.Type: GrantFiled: December 9, 2003Date of Patent: September 11, 2007Assignee: ASMO Co., Ltd.Inventors: Takeo Noda, Shouichi Yoshikawa, Yousuke Natsume, Osamu Kubota, Shigeo Nishio

Patent number: 7227287Abstract: A motor holder or a lower case defines therein a circuit accommodating chamber for accommodating a control circuit device. A side wall of the motor holder or the lower case that defines the circuit accommodating chamber has a vent for ventilating the chamber. A boundary section is formed between the motor holder and the lower case. An overhang extends from the motor holder. In a section of the circumference of the lower case, the overhang continuously covers the boundary section along the outer surface of the side wall of the lower case. A bulging portion is arranged to prevent water droplets from reaching the vent from the overhang. Therefore, the motor assembly prevents the integrally assembled control circuit device from being wet.Type: GrantFiled: May 3, 2006Date of Patent: June 5, 2007Assignee: Asmo Co., Ltd.Inventors: Takeo Noda, Akihiko Suzuki

Patent number: 7087653Abstract: A gas-to-liquid (GTL) process and system for converting a natural gas) into liquid hydrocarbons (e.g. diesel, naphtha, distillates, etc.) wherein the equipment subsystems from existing gas-to-methanol plants are re-utilized in the (GTL) process. The syngas generator from the methanol plant is used to generate syngas in the present process. The syngas is then adjusted to remove CO2 and H2 before the syngas is passed through a Fischer-Tropsch (FT) reactor to convert the syngas to liquid hydrocarbons. The FT reactor is comprised of the same equipment that was use previously to convert syngas into methanol except for the respective catalysts. The liquid hydrocarbons are then upgraded and separated into individual hydrocarbon products.Type: GrantFiled: March 19, 2004Date of Patent: August 8, 2006Assignee: World GTL, Inc.Inventors: Peter J. A. Tijm, David Loring, Leigh Takeo Noda

Patent number: 6836038Abstract: A motor includes a substantially cylinder-shaped motor yoke with an opening at one end, an end plate, and DC power input terminals. The end plate is positioned adjacent to the opening of the motor yoke, and the DC power input terminals are fixed to the end plate. The motor yoke has a grounding flange that protrudes from an outer periphery of the motor yoke adjacent to the opening. A negative terminal of the DC power input terminals has an elastic contact segment. The contact segment is pressed against the grounding flange to ground the motor yoke.Type: GrantFiled: January 31, 2003Date of Patent: December 28, 2004Assignee: ASMO Co., Ltd.Inventors: Takeo Noda, Akihiko Suzuki

Patent number: 6710493Abstract: A rotor and each magnet are configured to satisfy one of the following conditions: (D&pgr;/Z)Xn+T<X<(D&pgr;/Z)×(n+1)−T and (D&pgr;/Z)×(n−1)+T<X<(D&pgr;/Z)Xn−T. Here, Z is a number of cores. D is an outer diameter of the rotor. T is a circumferential dimension of a tooth of each core. X is a circumferential dimension between a circumferentially innermost one of first and second opposing points of a first tapered portion and a circumferentially innermost one of first and second opposing points of a second tapered portion. The first and second opposing points radially oppose first and second imaginary end circles, respectively, defined by outer peripheral surfaces of the cores. Furthermore, n is the number of the teeth that are entirely placed within a range defined by X when a circumferential center of one of the teeth is radially opposed to a circumferential center of the range defined by X.Type: GrantFiled: May 28, 2002Date of Patent: March 23, 2004Assignee: Asmo Co., Ltd.Inventors: Shouichi Yoshikawa, Takeo Noda, Akihiko Suzuki, Yasushi Ueda, Toshimoto Ito

Patent number: 4483405Abstract: An omnidirectional motorized wheelchair having front wheels consisting of a pair of free wheels, and rear wheels consisting of motor-operated wheels driven by electric motors independently of each other. This wheelchair can be moved forward and backward, turned to right and left, and turned in a fixed position. The motor-operated wheels are moved pivotally in the opposite directions by a steering unit to set these wheels to face in the lateral direction with respect to the rider. Thus, the wheelchair can be moved in the lateral direction with the rider facing forward, and it can also be turned while it is moved in the lateral direction.Type: GrantFiled: July 22, 1982Date of Patent: November 20, 1984Assignee: Koyu Enterprise, Inc.Inventors: Takeo Noda, Ichiro Tsunaki
