Abstract: In a nuclear reactor building of a steel plate concrete structure that houses a pressure containment vessel formed with a plurality of penetration ports penetrating the pressure containment vessel on the periphery thereof and includes a biological shielding wall disposed outside the pressure containment vessel. The pressure containment vessel is vertically divided into a plurality of blocks so that each of the blocks has one or more pressure containment vessel penetration ports arranged on a same horizontal plane, and the reactor building including the biological shielding wall is divided into a plurality of modules by the horizontal plane.

Abstract: Endless drive belts are provided in a spaced-apart relation to each other such that one endless driven belt is set in contact with one of these drive belts and the other endless driven belt is set in contact with the other drive belt. The one drive belt is driven by one pulse motor through one drive roller and that other drive belt is driven by the other pulse motor through the other drive roller. A bill is conveyed with its opposed edges gripped by the drive and driven belts. A controller measures the skew of the bill and bill-to-bill interval on the basis of output signals detected by forward-stage detecting units against the conveying bill and controls the respective rotational speeds of the one pulse motor and that other pulse motor on the basis of a result of measurement.

Abstract: A card reader-writer includes a body provided with a card inserting opening into which a card to which reading and writing of information can be made is inserted, magnetic heads arranged in the body to read and write information from and on the card, and a device for carrying the card which is inserted into the card inserting opening to the magnetic heads. The carrying device includes a card chucking unit for chucking the card and a carriage for moving the chucking unit along a certain passage. The position of the card chucked by the chucking unit is corrected by a card position adjusting or correcting unit.

Abstract: A motor having a stator which comprises a stator iron core 6 formed by fitting an inner ring magnetic pole portion 10 into an outer ring yoke portion 5, the inner ring magnetic pole portion 10 having slots 8 and magnetic poles 7; an insulating member 11 covering the inner ring magnetic pole portion of the stator iron core; a funnel-like insulating 13 which is formed integrally with the insulating member 11 to cover an end surface 14 of the inner ring magnetic pole portion 10 and which has a first through hole 15 for rotary shaft to communicate with the central portion of the inner ring magnetic pole portion 10 spool frames 23, 24 with pins 28 formed on the magnetic poles 7 so as to be integral with the insulating member 13; a rotor 16 inserted in the inner ring magnetic pole portion; 10; a funnel-like insulating cover 18 having a second through hole 20 for rotary shaft which is in alignment with the first through hole 15, the insulating cover 18 being mounted on the other end surface 12 of the inner ring magn

Abstract: In the present invention there is disclosed an improved serial type dot printer. According to the printer, the mutual magnetic interference between the magnetic circuits that are provided for each of the printing hammers to act as their respective driving sources, can be avoided by an appropriate choice of the distance between the printing pins, and at the same time, the power supply capacity can be reduced.
