Abstract: A color image forming apparatus is provided wherein toner images formed on a plurality of image carriers are primarily transferred onto an intermediate transfer object, and then, are secondarily transferred onto a recording sheet. The color image-forming apparatus includes an intermediate transfer member, a longitudinal direction of which is arranged in substantially a vertical direction, and onto which toner images formed on image carriers are sequentially transferred in such a manner that the toner images overlap relative to each other so as to form a color toner image on the intermediate transfer member. In addition, a transferring device is provided to transfer the color toner image formed on the intermediate transfer member onto a transfer sheet. The intermediate transfer member and the image carriers are integrated into a rack, and the rack is drawable in substantially a horizontal direction with respect to a mainframe of the color image-forming apparatus.

Abstract: With a structural laminated wood (L.V.L) made up by laminating and bonding a plurality of wood laminas, the wood laminas are respectively formed in an approximate L-shape or U-shape in one plane, and the structural laminated wood is formed in an approximate L-shape or U-shape having two side portions of predetermined lengths approximately at right angles to each other. Moreover, with a construction member for a framework structure for buildings, where the construction member uses the structural laminated wood, one side portion of the structural laminated wood is made at least a part of a vertical construction member, and the other side portion is made at least a part of a transverse construction member.

Abstract: A throwaway drill capable of machining a workpiece stably in a balanced manner even under high-efficiency, high-load conditions and capable of disposing of chips efficiently and smoothly. The drill carries an outer insert and an inner insert. As shown, each insert has a plurality of cutting edges each having a curved crest, a first slope, and a second slope which is at least partially a curved line. The inner and outer inserts are arranged so that the cutting area to be cut by the outer insert alone is partially cut by a cutting edge portion of the inner insert near its corner, and the cutting area which to be cut by the inner insert alone is partially cut by the crest of one cutting edge of the outer insert.

Abstract: An image forming apparatus includes a plurality of toner reservoir for storing different toner, a developing unit composed of a plurality of developing devices, and a plurality of toner conveyors for conveying toner from the toner reservoir to the developing unit. Through-holes are formed in the developing unit, and an upper portion of each through-hole is connected with each toner conveyor in such a manner that an upper opening of each through-hole is opposed to an ejection port of each toner conveyor, so that toner drops from the toner conveyor into through-hole and is guided to each developing device.

Abstract: An image forming apparatus having a carriage which can be pulled out from an installed position thereof. The carriage supports a cartridge including an image forming body, at a pull-out position, and fixes the cartridge to a position at which an image can be formed, at the installed position of the carriage. When the carriage is located at the installed position, the carriage forms at least a part of the upper surface of a main body of the apparatus.

Abstract: Joint apparatus for construction members and a building construction are provided with standardized joint members including at least one of a basic joint member including a fitting protrusion of an approximately cross-figured lateral sectional shape, an end plate portion connected at a top or a bottom face of the fitting protrusion, and a projection extending upwardly from the end plate portion for fitting a groove of approximate straight line or cross-figured lateral sectional shape.
