Abstract: A radiation image capturing system includes a capturing room and a console. The capturing room includes a bucky apparatus, a radiation irradiating apparatus and a detecting unit. A plurality of portable radiation image capturing apparatuses can be loaded on the bucky apparatus. The radiation irradiating apparatus is able to simultaneously irradiate radiation to the plurality of portable radiation image capturing apparatuses. The console is associated with the capturing room and obtains capturing order information. The console allows the portable radiation image capturing apparatuses to advance to a capturing possible state when the console judges that capturing in the capturing order information is long length capturing. The console allows only one of the portable radiation image capturing apparatuses to advance to the capturing possible state when the console judges that the capturing is not the long length capturing.

Abstract: A magnet chuck has a piston assembly including a tube shaped permanent magnet and a core yoke able to move on the interior of a cylinder tube. The permanent magnet is provided on the outer periphery of the core yoke, is magnetized in the radial direction, and a magnetic sensor is attached to the side surface of the cylinder tube.

Abstract: A surface-coated cutting tool has excellent welding resistance and fracturing resistance and comprises a hard coating layer, including at least a lower layer and an upper layer, formed on a surface of a cutting tool body. The lower layer is formed of one layer or two or more layers of a TiC layer, a TiN layer, a TiCN layer, a TiCO layer, and a TiCNO layer. The upper layer is found as an Al2O3 layer on a surface of the lower layer. On at least an outermost surface of the upper layer of a rake face, a zirconium oxide layer is formed in an area ratio of 30% to 70%. The Al2O3 layer on the rake face has a tensile residual stress of 10 to 200 MPa and a surface roughness Ra is 0.25 ?m or less.

Abstract: A work tank of an electric discharge machining device can manually move up and down, open and close, and lock and unlock a door without using any mechanical components. The work tank includes: a box-shaped tank body having an open front surface and an openable and closable door; a pair of handle bars that are placed right and left of the tank body; a handle that is installed between front end parts of the pair of handle bars; a pair of door stays that are placed at right and left of the tank body; a guide rail that moves up and down the door stay hung from the handle bar; a load receiving unit that supports a load of the door stay; and a stopper that restricts downward rotation and a frontward movement of the handle bar at a predetermined rotation position.

Abstract: A workpiece mounting table (20) for an electric discharge machine, which machines a workpiece (12) by discharging electricity between an electrode and the workpiece (12) in an interior of a work tank (6) and removing a surface of the workpiece (12), includes a surface-plate mounting table (3) made of a conductive material and arranged at the bottom of the work tank (6), a plurality of insulating materials (2), each of which has a flat shape and is arranged and fixed on the surface-plate mounting table (3) with a gap (4) between the insulating materials (2) to constitute an insulating flat plate (30), and a surface plate (1) made of a metal material, fixed on the insulating flat plate (30) and insulated from the surface-plate mounting table (3) by the insulating flat plate (30), for fixing thereon the workpiece (12).

Abstract: A skid steering loader capable of performing on-the-spot rotation. The loader has a wheel-type handle, an accelerator pedal, and a drive lever for setting the loader to forward, neutral, and rearward positions. A control device receives a handle turn angle signal, an accelerator pedalling angle signal, and a drive instruction signal from the drive lever. The control device controls a drive mechanism for driving left and right wheels in response to these signals to thereby separately control the numbers of turns of and directions of rotation of the wheels. The skid steering loader can be operated by manipulating the accelerator, handle, and drive lever in same manner as an ordinary automotive vehicle.

Abstract: A charge pump bias generator constructed of P channel MOSFETs in an N type substrate is used to provide a negative bias to a P well containing active N-channel MOSFET circuit elements to reverse bias the N type source to P well junctions. Since the charge pump uses P channel FETs in an N substrate with the N substrate connected to the positive power supply, parasitic minority carrier injection by the charge pump is prevented.

Abstract: A semiconductor memory device which comprises a memory section formed of a first substrate region of a first conductivity type and a first MOS transistor of a second conductivity type which is formed in the first substrate region to act as a transfer gate; and a peripheral circuit constituted by a second MOS transistor of a first conductivity type and a third MOS transistor of a second conductivity type. A second substrate region of a second conductivity type in which the second MOS transistor is formed substantially surrounds the memory section.

Abstract: An insulated gate FET comprises a semiconductor substrate, source and drain regions formed in the surface of the semiconductor substrate in a manner spaced at a prescribed interval from each other, and a gate electrode provided on a surface portion of the substrate between the source and drain regions through an insulation layer. Depletion layers formed by the action of a buit-in-field are spread, respectively, into said semiconductor substrate from the source and drain regions, and these two depletion layers contact each other.
