Desirably said polishing compound is the compound in which water soluble organic solvent is contained. Further, present invention provides edge polishing method and surface polishing method by use of said polishing compound.
Abstract:
A mudguard structure for a straddle-ride vehicle suppresses the enlargement of an attachment portion of a mud shield plate and makes satisfactory the external appearance of the circumference of a rear fender. A mudguard has left and right erecting walls erecting to the rear from respective left and right outer edges thereof and a front-lower concave portion integrally continuing into a lower portion of a rear wheel runout concave portion of a rear fender. A box-like attachment portion for attachment to the rear fender is located at each of both, left and right, sides of the upper end portion of the mudguard.
Abstract:
An exterior cover (shroud) for a saddle-type vehicle is formed by integrally uniting a plurality of resin members including a front cover section and a rear cover section. The shroud is insert molded to form an overlapping part where the front cover section and the rear cover section overlap with each other. The front cover section has an external-appearance-surface side at the overlapping part. The rear cover section has a non-external-appearance-surface side, which overlaps with the front cover section at the overlapping part. The rear cover section has a rib extending on the non-external-appearance-surface side. Such exterior cover prevents a sink mark from being generated in the external appearance surface of the front cover section, and improves the external appearance of vehicle.
Abstract:
A silencer for a motorcycle has a front cup which has a tapered tubular shape, a center sleeve which is connected to the front cup, and a tail cup which is connected to the center sleeve. Since the front cup has a tapered tubular shape, the front cup is arranged such that a front end of the front cup is positioned in the vicinity of a main frame. A distal end of the silencer can be shifted frontward in the longitudinal direction of a vehicle compared to a silencer of a prior art. As a result, a length of the silencer can be increased while avoiding interference between the silencer and legs of a rider and hence, silencing performance of the silencer can be enhanced. Since the distal end of the silencer can be shifted frontward in the longitudinal direction of the vehicle, the concentration of a mass can be acquired.
Abstract:
A seat structure for a vehicle, such as a motorcycle, includes a seat arranged rearwardly of a fuel tank mounted on a vehicle body frame. The seat includes a cushion member, and a bottom plate for holding the cushion member. The cushion member is made of an elastic material. The bottom plate is fixed to the vehicle body frame and to the fuel tank. The cushion member includes a bulging portion which bulges forwardly from a front end portion of the bottom plate and onto an upper surface of a stepped portion of the fuel tank. The bulging portion is supported on the upper surface of the fuel tank.
Abstract:
A motorcycle has a rear fender configured for strength and rigidity when the rear fender is lifted upwardly, while minimizing mass thereof. The motorcycle includes main frame sections extending rearwardly from a head pipe, left and right pivot plates attached to rear ends of the main frame sections and extending downwardly, and a swing arm, having a front end supported on the pivot plates to be swingably movable thereon, and a rear end configured to support a rear wheel. The motorcycle also includes left and right seat rails for supporting a seat thereon, left and right reinforcing rods extending between the seat rails and the pivot plates, and a rear fender mounted on the seat rails above the rear wheel. The rear fender includes projecting portions supported at front end portions thereof by front mounting flanges, the projecting portions projecting forwardly and contacting the seat rails from above.
Abstract:
When a press jig is inserted into a jig insertion hole, an O-ring attached to the outer peripheral surface of the press jig is prevented from being caught on an air supply port opening to the inner peripheral surface of the jig insertion hole and damaged. In a sealing pump-up device 10, the opening diameter of an air supply port 58 opening to the inner peripheral surface of a jig insertion hole 44 provided at one end of an air supply path 60 is set smaller than the strand diameters of an O-ring 72 and an O-ring 96. Consequently, the width at the edge of the air supply ports 58 on which the O-rings 72, 96 may possibly be caught can be made sufficiently smaller than the strand diameter of the O-rings 72, 96. When the O-rings 72, 96 pass on the inner peripheral side of the air supply ports 58 in a state of press contact with the inner peripheral surface of the jig insertion hole 44, the amount by which the O-rings 72, 96 are deformed (restored) in order to swell to the outer peripheral side so that a portion thereof fits into the air supply ports 58, can be reduced sufficiently.
Abstract:
A semiconductor manufacturing method and apparatus is provided that can improve uniformity of processing time of oxidation thickness. When starting a heat oxidation process, a time for optimum oxidation processing in the process management system is calculated based on atmospheric pressure data, a target thickness of that process, oxidization time, thickness data and atmospheric pressure data in the immediately preceding process under the same oxidization processing job. The optimum system comprises a process management system such as a host computer, a device having a barometer, a heat oxidation-processing device and a thickness-measuring device. The host computer, the barometer, the heat oxidation processing device and the thickness-measuring device are connected via a network so as to transmit data to and from each device.
