Title: Bucket beat
Inventor: IZUKI NORIYASU
IPC: A47C7/14
Filed: 1984-08-30
Abstract: PURPOSE:To allow a crew to get on or off a car smoothly keeping out of the way by configurating one side of a side frame in such a manner that it is made to be rotational against a seat frame allowing it to be locked in a stand-up condition only when the crew takes a seat. CONSTITUTION:On the load being applied to an upheval (a) on one side of a seat cushion Sc while a crew is taking a seat, a side frame 3 is allowed to be knocked down outside overcoming the resistance of a torsional coil spring 9. This permits the upheaval (a) to be on the same surface of the center section of the seat cushion Sc allowing the crew to sit down on the seat as usual. In this case, the weight of the crew causes a pad pulling bar 19 to be deflected downward allowing an engaging plate 14 to swing counterclockwise with center at the shaft pin 15, since the engaging plate is connected with the end 18a of the pad pulling bar. Subsequently, an engaging pin 16 comes in contact with an engaging projection 12 on a plate 3a of the side frame 3 which is in a stand-up condition. Then the plate 3a is supported by both the engaging pin 16 and a flange section 11 allowing the rotational rame 3 to be locked in a stand-up condition.

Title: Rotating electric machine
Inventor: SHINSHI TADAHIKO
IPC: H02K5/00
Filed: 1994-08-02
Abstract: PURPOSE:To obtain a rotating electric machine in which mechanical rigidity is ensured in order to suppress deformation due to a transverse tensile force, in which the plate thickness in the central part of an aluminum-alloy frame generating much heat by a stator is made thin and whose thermal resistance is reduced by Na method wherein the wall thickness on the side of an output shaft and on the side opposite to the output shaft is made thicker than that of the central part which fixes the stator at the aluminum-alloy frame. CONSTITUTION:A stator 10 is shrinkage-fitted or force-fitted to the central part of a frame 11. The plate thickness at the end part of the frame 11 is changed smoothly so as to become at about 60% or lower of a plate thickness in the central part. Thereby, since the plate thickness is sufficient at the end part of the frame 11 in which a transverse tensile force acts largely, mechanical rigidity can be ensured sufficiently. In addition, since the plate thickness is changed smoothly, a cooling wind flows easily along the surface of the frame 11. In addition, since the plate thickness in the central part, generating much heat, of the stator 10 is thin, the heat generated from the stator 10 can be conducted well to the outside.
