Patent number: 6758181Abstract: A starter which is capable of smoothly and reliably starting an internal combustion engine even though an electric motor employed is relatively small in size and output, thereby making it possible to minimize power consumption of the electric motor, to miniaturize the capacity of battery, to reduce the total weight of the starter, to enhance the durability of the starter, and to suppress the generation of failure of the starter. This starter comprises a buffering/power-accumulating means disposed midway along a power transmission system between a driving member and a driven member, wherein the buffering/power-accumulating means is enabled, during the driving process, to accumulate the power supplied through the driving process while alleviating any impact to the driven member, the accumulated power being subsequently employed to drive the driven member, and wherein the driving member is an electric motor.Type: GrantFiled: January 14, 2002Date of Patent: July 6, 2004Assignee: Kioritz CorporationInventors: Giichi Iida, Junichi Akaike

Patent number: 6712593Abstract: The present invention is directed to split bodies for assembling a synthetic resin blower fan by a hollow article molding process. The split bodies have a first split body which includes a circular base portion and vanes extending radially and a second split body assembled on top of said first split body and is in a doughnut-shaped cap with an air inlet at the center thereof. Air channels are formed between adjacent pair of the vanes. The second split body includes a plurality of grooves which are formed on an inner surface opposite from the first split body in an assembled state. Each of the grooves extends radially along an edge of a corresponding vane and is adapted to be closed by the edge so as to define a flow path for allowing a molten synthetic resin to pass therethrough.Type: GrantFiled: November 2, 2001Date of Patent: March 30, 2004Assignee: Kioritz CorporationInventors: Toshio Takahashi, Giichi Iida

Patent number: 6619409Abstract: A vibration-isolating member is formed of an elastic material, and has a mounting hole at the center thereof, a large diameter section at an end of the mounting hole, a groove at the periphery of the large diameter section, and a flange. One of a vibration-source-side member and a vibration-receiving member is fitted into each of the large diameter section and the groove. An end opposite from the large diameter section is secured to one of the vibration-receiving member and the vibration-source-side member by a mounting member. Since the inside diameter of the large diameter section is larger than any other part of the mounting hole, either of the vibration-source-side member or the vibration-receiving member and the mounting member can be received. The flange prevents the vibration-isolating member from disengaging from one of the vibration-source-side member and the vibration-receiving member.Type: GrantFiled: July 27, 2001Date of Patent: September 16, 2003Assignee: Kioritz Corp.Inventor: Giichi Iida
