Abstract: A punch press includes plural dies and plural punches, and punches a work by a punch and a die that are set at a work position. The punch press includes a lifter for lifting the die to be set at the work position up to a path line of the work, a die-support member movably provided on a die-side of the lifter, and a die supporter provided on the die-support member for supporting the die set at the work position in a state where the die has been selectively lifted up to the path line by the lifter. According to the punch press, contacts between a work and dies while conveying the work can be prevented.

Abstract: Disclosed is a highly efficient turbine nozzle blade that reduces the number of blades in an axial-flow turbine while reducing secondary-flow loss. In the nozzle blade, when a differential pressure between a pressure side and a suction side of each blade, at the same axial chord position of the blade, is defined as a load of the blade, and a ratio between axial chord length “Cx” of the blade and an axial distance “xp” from a leading edge of the blade at a maximum load position that maximizes the blade load is defined as a maximum load relative position, Cx is greater at a hub and tip than at an intermediate vertical portion, and simultaneously a maximum load relative position at the hub and tip is set to be nearer to a trailing edge thereof than a maximum load relative position of the intermediate vertical portion of the blade.

Abstract: A gas inlet member is fixed to a valve body and an upper part stem and a lower part stem are inserted slidably into a vertical stem opening above the gas inlet member. A valve member is provided in the gas inlet member and a gas flow passage is formed. A ring-like seal member is mounted onto the upper part stem and an O-ring is fixed to the lower part stem. A part of the valve member disposed at the lower end portion of the valve body is merely inserted into a gas container. It is possible to carry out a stable operation of the gas supply valve in spite of a change of environment due to vibration or heat while driving a vehicle.

Abstract: A molding apparatus includes a molding box structure with an adjustable internal spacing, a metal mold accommodated in the molding box structure, a thermally expanding, member accommodated in the molding box structure to be arranged in pressure transmitting, relation with the mold member, and a temperature adjuster for adjusting a temperature of the thermally expanding member so that the material thermally expands and contracts. The molding box structure includes a pair of support elements fixed by threaded struts and nuts so that the support plates are spaced from each other. The apparatus further includes an auxiliary pressurizing mechanism including two wedge-shaped plates having respective tapered face, and spaced from each other so that the tapered faces are opposed to each other and so that an overlap between them is adjustable, and an actuator for driving the wedge-shaped plates.
