  • Publication number: 20010015746
    Abstract: In an ink drying portion, a conveying roller and a rigid roller are rotated by driving force of a driving roller which is transmitted through a driving belt. Air in a housing is discharged by means of a fan and air is sucked into the housing through a clearance between the conveying rollers. A paper conveyed into the ink drying portion is continuously held along a paper drying passageway by the air sucking effect of the discharge of the fan and is consecutively conveyed along the paper drying passageway through the conveying roller. An ink on the paper is dried by direct irradiation with infrared rays from an infrared heat source or by indirect irradiation with infrared rays reflected by a reflecting plate.

  • Patent number: 6275875
    Abstract: A memory card stores programs and constant data for both a master CPU and a slave CPU. The master CPU identifies a header portion of the memory card attached to a card adapter to identify the storage locations of the data for the master CPU and the slave CPU, the size thereof and the addresses in RAMs at which the data for the master CPU and that for the slave CPU are stored. The master CPU writes the data for the master CPU in the RAM while it serially transfers the data for the slave CPU to the slave CPU and writes it in the RAM for the slave CPU. The individual CPUs perform control of loads according to the data in the RAMs.

  • Patent number: 6202469
    Abstract: A gas concentration detecting device for detecting the concentration of a component, such as an oxygen in an exhaust gas of an internal combustion engine. The device has a concentration detecting body 2 for detecting the oxygen and a cover 3 of a double wall structure which is for encircling the portion of the detecting body opened to the flow of the exhaust gas to be detected. The cover 3 has, at its axial tip end wall, a plurality of holes 33 and 34 arranged in such a manner that one of the holes functions as a gas inlet hole and the other hole functions as a gas outlet hole in order to cause the gas to be smoothly ventilated. The cover has, at its side, a wall of a closed structure with no hole for the passage of the gas, which is effective for preventing the cover 3 and the detecting body 2 from being cooled by the exhaust gas, thereby enhancing a heat retaining capacity, thereby preventing particulates from being deposited.

  • Patent number: 6154627
    Abstract: An object of the present invention is to prevent an electrical breakdown of a toner layer and an occurrence of overcurrent, thereby preventing quality of image from being degraded at the time of development, when development with one-component toner is conducted using a developing roller of low resistance. The resistance value Rd of a developing roller which carries and conveys one-component toner in a manner of coming into contact with a photoconductor which bears an electrostatic latent image, is defined as Rd=.rho.d.multidot.(Dd1/S1), wherein S1 (cm.sup.2) is an area in which the developing roller comes into contact with the static image bearing member via a toner layer, Dd1 (cm) is a layer thickness of a semiconductive layer which composes the developing roller, and .rho.d (.OMEGA..multidot.cm) is a volume resistivity thereof. The range of the resistance Rd is set as 10.sup.4 <Rd<10.sup.5 and the resistance Rt (.OMEGA.) of the toner layer is set as Rt>5.times.10.sup.7.

  • Patent number: 6149523
    Abstract: The objective of this invention is to provide an image synthesis method, sound synthesis method, games machine and information storage medium for making it easy to learn a complicated operating sequence from a game controller. This system determines whether an input sequence by which operating buttons are pressed in sequence matches a standard sequence that is specified by standard operations (41) to (51). If the input sequence matches, a matching identification symbol lights up. When an operating button is pressed, an identification sound that identifies the press operating button is output. The player can perceive the operations to be input and the operations that the player has input from these identification symbols and sounds. This makes it easy to acquire special techniques used in a fighting game. Outputting identification symbols and sounds in this manner is particularly effective in a training mode.

  • Patent number: 6064463
    Abstract: A blade is pressed against a developing roller for regulating the amount of toner which is deposited on a surface of the developing roller. The blade is formed with a slant face at its tip end, to which the toner is transported along a direction of rotation of the developing roller. An angle of aperture .theta. at a toner inlet portion defined by the developing roller and the slant face is set at 12.5.degree. or more, the angle of aperture counting in an angle .psi. of the slant face, elastic deformation and radius (R) of the developing roller, and an angle .alpha. related to a nip width w on which the blade contacts with the developing roller. Such an angle of aperture .theta. provides a great allowance for a free length l of the blade, thereby permitting the blade to maintain a constant toner mass for forming a uniform toner layer.

  • Patent number: 6035171
    Abstract: The object of the invention is to certainly remove and certainly recover the charged toner remaining on a developing roller after development. A single component toner which is delivered to the developing roller via a toner-supplying roller is made into a relatively thin layer of a predetermined thickness with a charging plate and is frictionally charged with a given quantity of electric charge. Subsequently, the toner is adhered on a photoreceptor drum along by the electrostatic latent image to develop an image at the developing region at which the developing roller comes into contact with the photoreceptor drum. After development, the electric charge of the toner layer on the developing roller is removed with an electric-charge-removing sheet. The toner after development is recovered into a toner hopper via the toner-supplying roller.

  • Patent number: 5832112
    Abstract: A color image processing apparatus that prevents counterfeiting by detecting specific originals with high precision. Although general banknotes have graphic patterns drawn on uniform density portions, the tonality percepted by human eye is the mixture of the tonality of a graphic portion and the tonality of a uniform density portion. In consideration of the mixed tonality sensed by human eye, the apparatus smoothes a read image signal to generate mixed tonality for judgment, thus improves judgment precision. The total judgment of existence/absence of specific original is made by performing m judgments on m (m>n) judging conditions using the tonality data of pre-registered n (n: positive integer) specific originals.
