Abstract: An image forming apparatus such as an ink jet printer or a laser beam printer include an ink or toner cartridge loading portion and a display portion to show the remaining amount of the ink or the toner. The ink or toner cartridge loaded in the ink or toner cartridge loading portion and the display portion are viewable together at once.

Abstract: The surface layer of a receptive layer has a water-absorbing property, and when the surface layer of the receptive layer is glossy and a layer to be printed covers up to a clamp area, the medium has a high possibility of causing a sticking of the receptive layer to a chucking mechanism in a drive. For this reason, an optical disk has been demanded which does not cause the peeling of the receptive layer in the clamp area while being used as the medium, provides a clear printed image, and copes with a high-resolution wide printing. In order to make the surface of the receptive layer not stick to the chucking mechanism of the drive, it is necessary to roughen the surface, but when a colored fine particle is contained in the receptive layer, a printed image on the receptive layer becomes unclear.

Abstract: A cigarette testing apparatus includes a ventilation-characteristic measuring section having a ventilation vessel which is disposed horizontally so as to reduce the vertical dimension of the apparatus. A cigarette is supplied in a horizontal position from a cigarette supplying section to a weight measuring section where the cigarette weight is measured. The cigarette ejected therefrom is transferred to a circumference measuring section, a ventilation-characteristic measuring section and a length/hardness measuring section in this order in a condition that the horizontal position is kept unchanged. In these sections, the circumference, ventilation characteristic, length and hardness of the cigarette are measured in sequence.

Abstract: An image forming apparatus includes an open interior space that retains ejected printed sheets. The apparatus includes a scanner that operates in a book-scanning mode of operation and a printer that includes a sheet ejection side wall in which an opening is formed for ejecting a printed sheet there through and a pair of support walls for supporting the scanner thereon. Each of the pair of support walls is orthogonal to the sheet ejection side wall and shorter in length than a length of the scanner in a longitudinal direction. In the image forming apparatus, the scanner is mounted on the sheet ejection side wall and the pair of support walls in a way such that a front part of the scanner projects in a horizontal direction from front edge sides of the sheet ejection side wall and the pair of support walls so that an interior space for handling the printed sheet is formed under a bottom part of the scanner that projects from the front edge sides of the sheet ejection side wall and the pair of support walls.

Abstract: In a method and apparatus for discriminating a coal species, discriminating values of coal species/properties are prepared corresponding to coal ranks, a coal to be discriminated is irradiated with near-infrared rays having different wavelengths, and light of near-infrared rays reflected from the coal is received; Aborbances of the coal are acquired, and the coal species/property discriminating value of the coal is discriminated on the basis of the absorbances and a prescribed calibration curve.

Abstract: There is provided a stamper for producing a recording medium exhibiting excellent durability and capable of stably forming projections and pits and a method of producing the stamper. A stamper for producing a recording medium comprising projections and pits in a predetermined pattern on the surface thereof, wherein a value of tan .theta..sup.-1 obtainable from an enlargement angle .theta. of an output from a cartridge with respect to an enlargement of an output denoting a load measured by a test of scratching the surface having the projections and pits under conditions that a diameter of a stylus is 100 .mu.m and a loading speed of 1 .mu.m/second is 1.3 or more.

Abstract: A floppy disk unit including a cartridge case or a jacket, a flexible magnetic disk rotatably accommodated in the cartridge case or the jacket, and liners disposed on the inner surface of the cartridge case or the jacket, wherein at least the surface layer of each of the liners in sliding contact with the magnetic disk is made from a fiber material such as rayon fiber, polyamide fiber, polyester fiber, or polynosic rayon fiber, each fiber having a diameter of 10 to 30 .mu.m, and the fiber material contains inorganic oxide material powder such as titanium oxide having an average diameter of 0.01 to 1 .mu.m by weight ratio 0.1 to 10%.

Abstract: A welding gun provided with a backup cylinder is characterized in that the welding gun is moved toward a workpiece by a welding robot an end of which is connected to the welding gun via a bracket, then one electrode is brought into contact with the workpiece by a backup cylinder so that the workpiece is held by one electrode, thereafter the other electrode is brought into contact with the workpiece by a pressure application cylinder so that the pressure force is applied to the workpiece by both the electrodes for welding operation.

Abstract: Connecting metal fittings for resistance welder comprise receiver metal fittings connected to transformer side and clamping metal fittings connected to a resistance welding gun side. The receiver metal fittings include terminal strips and power supply connecting plates, both provided on the transformer side and fixed thereon, and a pair of rotatable clamping handles having stopping cylinders and stopping pins both provided on a handle lever. The second metal fittings include a shaft lever penetrating the terminal strips on the welding gun side and being inserted into notched grooves formed in tips of the power supply connecting plates, spring sockets being slidably inserted into both ends of the shaft lever, plate springs disposed between the spring sockets and power supply connecting plates, and a cam having stopping levers composed of stopping hooks formed on the tips thereof, and fixed thereon and adapted to make contact with the spring sockets.

Abstract: A primary cable apparatus for a robot welding gun having a cable including a pair of conductors operatively connected to a welding power source, a grounding conductor, a shield wire surrounding the pair of conductors and the grounding conductor and an insulation coating operatively positioned around the shield wire.
