An object of the present invention is to provide a turbine external compartment, a frame for a turbine external compartment, and a method of constructing a frame for a turbine external compartment that can improve a flow of steam inside of the compartment and can enhance the rigidity of the compartment using a simple structure. A turbine external compartment according to the present invention is placed in a frame having a steel-plate reinforced concrete structure obtained by filling a space between a plurality of steel plates with concrete. The turbine external compartment includes a lower half part having a side plate part or an end plate part made of the steel plates that constitute the frame.

A steam turbine has an outer casing that is divided into an upper casing and a lower casing (a lower block) on a horizontal plane through which a rotor passes. The upper casing is divided into a middle block having a through hole and an upper block having a top panel, that is, into a portion including at least a part of the through hole through which the rotor penetrates. With this configuration, machining of a bellows fitting unit provided in an end-plate cone portion can be performed in existing facilities such as a factory, in a state that the lower block and the middle block are assembled without assembling the upper block.

To feed a plurality of cut sheets of paper to a recorder, in a one-by-one picking up manner, a stack plate supports the cut sheets placed on a paper stacking side thereof, a spring member is provided on an opposite side to the paper stacking side of the stack plate, a feed roller is rotated to force out in a paper feed direction a top sheet of the cut sheets placed on the stack plate, as the stack plate is elastically urged by the spring member toward the feed roller, a pawl member separates the top sheet from the rest, as it is forced in the paper feed direction by the feed roller, and a convex stripe part is provided on the paper stacking side of the stack plate, the stripe part extending in a crossing direction with the paper feed direction.

Device and method for feeding cut sheets of paper in a one-by-one

A force detector/indicator is disclosed which is provided with a piezoelectric plate that generates voltage when subjected to operation force or pressure, and a liquid crystal display (LCD) having a threshold value sufficiently lower than the generated voltage of the piezoelectric plate, the piezoelectric plate and the liquid crystal display being electrically connected such that generated voltage from the piezoelectric plate acts as an input signal to turn on the display of the liquid crystal display. In addition, a high-resistance conductor for discharge is provided between the two electrode lines making up a circuit connecting the piezoelectric plate and liquid crystal display.

Force detector/indicator

In a layer structure oxide in crystallite form having a composition of the formula: AMO.sub.2 wherein A is Li or Na and M is Co, Ni, Fe or Cr, at least one additive element Z which is Bi, Pb or B is present in the form of an oxide on the surface of crystallites or between crystallites. Atomic ratio Z/M is from 0.0001 to 0.1. Since the crystallites have an increased size, the layer structure oxide has improved properties and is suitable for use as a positive electrode material of a secondary cell.

A tape recorder consisting of a main body, a cassette lid which opens and closes the cassette room and touch-type switches provided on the cassette lid to execute various types of operation modes.

Tape recorder

An apparatus for moving the pinch roller and the magnetic head of a tape recorder into their operative positions comprises a small size motor which supplies a drive to a pair of drive and driven members such as the combination of a pinion and a rack. The drive is transmitted via the pair of members to a movable member which carries the pinch roller and magnetic head, thus moving the pinch roller and the magnetic head to their operative positions.

A back spacing apparatus for a transcribing machine comprises a first means for providing a first signal (a) corresponding to the period of rotation of a supply reel or a take-up reel, a drive source for rewinding a tape toward the supply reel and a second means for providing electric energy (Tm.times.V) corresponding to the period (Tm) of the first signal (a) to the drive source for rewinding to vary the r.p.m. of the supply reel at the time of rewinding the tape toward the supply reel or the period of the rewinding operation according to the first signal (a). The magnitude (Tm.times.V) of the electric energy is varied in accordance with the period (Tm) of the first signal (a) for making the length of the tape rewound toward the supply reel substantially constant irrespective of the diameter of the tape rolled on the supply reel.
