  • Publication number: 20050281964
    Abstract: The invention relates to a manufacturing method of an image recording medium wherein during the process of cutting a long roll body of the medium into sheet like product the curl tendency, a cause of poor printer feedability, is removed, and at the same time the generation of cracking in a recording layer is suppressed. In the manufacturing method a web of a long roll body, a sheet like material of a paper substrate with thermoplastic resin layers formed on both surfaces one of which also has a recording layer with the long roll body wound such that this recording layer surface is on the outside, is unwound into a cutting device whilst at the same time a straightening element of a roller of diameter between 8 mm and 16 mm is pressed against the side of the recording layer with a wrap angle that is less than 60 degrees.

  • Publication number: 20050270357
    Abstract: A preparation method for an inkjet recording paper obtained by cutting an inkjet recording sheet which has been formed in advance with an image wherein cutting is carried out by: providing a surface of the inkjet recording sheet before cutting with a cut location mark; detecting the cut location mark using a reading sensor; and cutting the inkjet recording sheet.

  • Patent number: 6919707
    Abstract: A method for controlling and addressing a battery power source device having a plurality of battery pack systems connected in parallel or serially in parallel, each battery pack system having a battery pack block and a battery ECU connected thereto, is provided. The battery ECUs are connected to each other over communication lines, and a plurality of address setting terminals and address lines are connected to each other differently to provide a unique address to each battery ECU. When an abnormal state is detected in one of the battery pack blocks over the communication line, control is provided to the abnormal one of the battery pack blocks, identified by its address, to turn off its open/close relay contact to disconnect it from the parallel or the serial parallel connection, thereby preventing the function of the entire battery power source device from being stopped or degraded.

  • Publication number: 20040255743
    Abstract: A discoid lower blade and a discoid upper blade, having a sharper knife angle compared with that of the lower blade, are arranged such that rotational axes thereof are parallel to each other, and portions of the blades overlap one another in the direction that the rotational axes extend. A sheet with a coating layer on one side is fed through and shear-cut between the upper and lower blades in the direction perpendicular to the rotational axes, with the surface of the sheet opposite the coating layer in contact with a periphery of the lower blade while the blades are rotated. When the sheet is shear-cut, a contact start position, where contact between the sheet and the upper blade starts, is positioned upstream in the feed direction of the sheet but outside a contacting area of the sheet, where the sheet contacts the periphery of the lower cutting blade.

  • Patent number: 6612100
    Abstract: A protective cover that is pre-folded by a protective cover pre-folding apparatus is supplied to a pack producing apparatus. After sheets are stacked on the protective cover, the protective cover is fully folded onto the sheets to produce a pack, which is then inserted into a bag to produce a package. The package is then delivered from a package stacking apparatus.

  • Patent number: 4496824
    Abstract: A method and circuit for controlling the temperature of heat generating elements of a thermal transfer type thermal printing head is presented. The temperature of the thermal printing head is compared with preset low and high temperatures, within this range a normal thermal printing is effected. When the printer head temperature is high above the high preset temperature, a blower is energized in order to air-cool the printer head surface. When the printer head temperature goes lower than the preset low temperature, then the printing head is lifted up apart from the platen and thereafter all of the heat generating elements are heated up. The latter heating operation can be carried out prior to the start of the thermal transfer operation or during the thermal transfer operation by intermittently halting the operation.

  • Patent number: 4071905
    Abstract: A binary full adder/subtractor circuit includes an exclusive OR gate operating upon augend/minuend and addend/subtrahend binary input signals. The sum/difference output from the circuit is the carry/borrow input signal or its inverse depending upon the output state of the exclusive OR gate. The carry/borrow output of the circuit comprises either the carry/borrow input or the addend/subtrahend input, as determined by the output of the exclusive OR gate and by an operation (sum/difference) specifying input signal.
