An object is to improve the operational reliability of a gas turbine by suppressing thermal stress and thermal deformation acting on the rotor of the gas turbine. The gas turbine has a rotor shaft constructed by arranging, in an axial direction in turn, a plurality of discs each having a plurality of combustion gas-driven moving blades annularly arranged on the peripheral portion and spacers arranged between the discs, and is characterized in that gap portions are formed between a region, on the rotor shaft center portion side, of the above-mentioned discs facing the spacers and spacers adjacent thereto, contact surfaces are formed both of which contact on both a region, on the rotor peripheral side, of the above-mentioned discs facing the spacers and adjacent spacers thereto, and a third flow path leading fluid to the above-mentioned gap portions is provided.

A turbine rotor for a gas turbine includes first and second wheels each having turbine blades fixed to a peripheral portion thereof, and a spacer arranged so as to be sandwiched between the first and second wheels. A partitioning member is provided between the spacer and at least one of the first and second wheels. Coolant paths in which coolant for cooling the turbine blades flows, are provided inside the turbine blades. A cavity formed by the partitioning member and the spacer is provided in a recovery course through which the coolant passed through the coolant paths is exhausted from the turbine blades.

A method and apparatus for enabling a processor to execute processing routine even if a power-source voltage drop occurs during processing. When an ignition key switch 102 is closed, voltage VB is supplied from a vehicle-mounted battery B1 to a comparator AMP of a CPU 108 and to a power-source stabilizer circuit 201 of a regulator 200. Also, capacitors C1 and C2 are charged with a load from the vehicle-mounted battery B1. Even if the power-source line is momentarily interrupted while in this state, the capacitor C1 has already been charged, and so the transition of the drop in voltage VB is gradual compared with a case wherein the capacitor C1 is absent. Additionally, because the capacitor C2 has already been charged, voltage VCC supplied to the CPU 108 from the regulator 200 is held at a fixed value for a certain interval. Because of this, the drop in voltage VCC is delayed and the power source is switched from the vehicle-mounted battery B1 to a battery B2, thereby allowing the CPU 108 to continue to perform uninterrupted data processing.

A time required for a copying operation is shortened in making duplex copies from simplex documents. In a copying machine provided with a recirculating document feeder for feeding documents one by one from a document container to an exposure region and returning the exposed documents to the document container, when the documents are circulated prior to the copying operation so as to count the number thereof, the copying operation is started immediately in the case where the number of the documents is detected before a first document passes the exposure region.

Based on whether image formation is to be performed on an one side or both sides of record paper, and on whether image data concerning image formation is image data of an one-sided document or image data of a double-sided document, it is judged whether a blank page or a blank sheet whose both sides are blank pages is included, and image formation is performed excluding said blank page or both sides of the blank sheet based on said judgment result.

On a case member of a semiconductor device, a screw block terminal or the like for connection to external equipment is attached. The screw block terminal or the like arranged on a region inside a base plate is attached to a terminal attachment member. Terminal attachment member has wall-like bodies, similar to wall-like bodies formed on a sidewall portion, formed along the direction of extension of terminal attachment member. On one end of terminal attachment member in the direction of extension, a side fitting portion is formed that corresponds to the wall-like body, and by fitting the side fitting portion to a space between sidewall portion and the wall-like body, terminal attachment member is fixed on case member. Thus, a semiconductor device is provided that allows high degree of freedom with simpler structure, as to the position of attaching a screw block terminal or a pin terminal to the case member.
