Abstract: A conveyance route switching mechanism and a paper sheet handling apparatus that includes the conveyance route switching mechanism include a driving source, a gate, a first gear, and an internal gear. The driving source includes a driving shaft. The gate includes a gate shaft, and a blade that is provided on the gate shaft, and switches conveyance routes of paper sheets. The first gear is provided on the gate shaft. The internal gear meshes with the first gear. According to rotation of the driving shaft, the gate shaft rotates on an axis of the gate shaft, and revolves with the driving shaft as a rotation center while the first gear meshes with the internal gear.

Abstract: An object of the present invention is to provide a recombinant phage having high safety and excellent practicality and usefulness. Provided are a recombinant bacteriophage which is deprived of its proliferative capacity and can infect only once due to the fact that a bacteriophage genome in which a part of a virion constituent gene is deleted is stored in a head, and a method for preparing the same. In addition, provided are a recombinant bacteriophage which is deprived of its proliferative capacity and can infect only once due to the fact that a plasmid having a packaging site and encoding a target gene is stored in a head, and a method for preparing the same.

Abstract: A method of manufacturing a billet for cold forging according to the present invention is characterized by the first spheroidizing annealing step of spheroidizing a carbide in a blank, the drawing step of drawing the blank at a predetermined sectional area reduction ratio after the first spheroidizing annealing step, and the second spheroidizing annealing step of promoting the dispersion of the internal carbide for an increased spheroidizing ratio after the drawing step. The drawing step has a drawing ratio of approximately 20%. The blank is cut to a desired dimension between said first spheroidizing annealing step and said second spheroidizing annealing step.

Abstract: A method of, and an apparatus for extruding a billet of a light metal alloy, wherein the billet has an outer diameter smaller than a maximum configuration width and larger than a minimum configuration width of the die hole at its entry side. The billet is pressurized and extruded by a stem to form a preshaped portion which is larger than the entry side configuration of the die hole, at a frontal end portion of the billet near an entry portion of the die hole. The preshaped portion of the billet is subsequently shaped by the die hole into an extruded shape corresponding to the cross-sectional shape of the die hole and of parts formed from the extruded billet, e.g., of an automobile suspension arm. A reduced resistance and a minimized extrusion pressure upon extrusion of a light metal alloy result from the preshaping of the billet and enable realization of a compact and less expensive arrangement of the production facility.

Abstract: An X-ray imaging diagnostic apparatus emitting a low X-ray radiation dose is disclosed as comprising an X-ray generating source for exposing an object, an optical system having a fluorescent screen for receiving the X-ray image at an aperture portion thereof, a high sensitivity imaging device coupled directly to the optical system and receiving an X-ray image from the fluorescent screen for radiographing the X-ray image, a control unit for amplifying the output from the high sensitivity imaging device and for controlling the exposure time of X-ray radiation emitted from the X-ray generating source, an image storing memory circuit connected to the control unit for storing an image signal therefrom and a monitor circuit for displaying the image signal.
