Publication number: 20130136487Abstract: A cleaning device includes a first cleaning member, a first opposing member, a second cleaning member, a second opposing member, and a pressing member. The first and second cleaning members clean an outer surface of a belt member by coming into contact with the outer surface. The first and second opposing members are in contact with an inner face of the belt member at positions that are opposite the first and second cleaning members. The pressing member is disposed between the first and second opposing members and is in contact with the outer surface of the belt member. The pressing member presses a portion of the belt member that is located between the first and second opposing members from an outer surface side of the belt member toward an inner face side of the belt member.Type: ApplicationFiled: May 25, 2012Publication date: May 30, 2013Applicant: FUJI XEROX CO., LTD.Inventors: Kaoru MATSUSHITA, Kazuyoshi HAGIWARA, Kazutoshi SUGITANI, Kuniaki TANAKA, Koichi SATO, Yuji KAMIKAWA, Koji DEGUCHI, Yusuke SAKAI

Patent number: 6341906Abstract: A tape cassette is set in a cassette accommodating section of a tape printer. A magnetically affixable printing tape is fed out from a holding reel along with an ink ribbon having a non-magnetic ink layer formed thereon across a cut in the tape cassette and conveyed through between a thermal head and a platen roller while being pressed by those elements. The printing tape comprises a printing layer and a magnetic layer pasted to the printing layer. The magnetic layer is magnetized such that S and N poles are alternately arranged longitudinally of the tape to thereby prevent turns of the tape roll from shifting widthwise. The magnetic layer has a coated fluorine layer formed thereon or has wrinkles formed thereon to thereby prevent blocking from occurring on a printing face of the tape due to its winding. Thus, the printing tape is conveyed in a correct attitude to enable a high quality image to be printed thereon.Type: GrantFiled: September 14, 1999Date of Patent: January 29, 2002Assignee: Casio Computer Co., Ltd.Inventors: Kenji Kobayashi, Kenzo Ito, Kenji Igarashi, Masayuki Ikeda, Kensaku Takeuchi, Kenji Suyama, Satoshi Kimura, Koji Deguchi

Patent number: 6190067Abstract: A tape cassette which contains a roll of a magnetically affixable printing tape formed around a holding reel and a roll of an ink ribbon formed around a holding reel and having a non-magnetic ink layer formed on the ribbon is set in a cassette accommodating section of a tape printer. The printing tape and the ink ribbon are fed out from their holding reels within the cassette across a cut in the tape cassette and through between a thermal head and a platen roller while being pressed by those elements to thereby perform printing. The printing tape comprises a printing layer and a magnetic layer pasted to the printing layer. S and N poles which extend lengthwise of the tape are alternately arranged widthwise on the magnetic layer. Thus, two overlapping poles of any two adjacent turns of the tape have the same polarity at any peripheral position.Type: GrantFiled: September 14, 1999Date of Patent: February 20, 2001Assignee: Casio Computer., Ltd.Inventors: Kenji Kobayashi, Kenzo Ito, Kenji Igarashi, Masayuki Ikeda, Kensaku Takeuchi, Kenji Suyama, Satoshi Kimura, Koji Deguchi

Patent number: 6072714Abstract: A first driver MOS transistor and a second driver MOS transistor are formed at the surface of a semiconductor substrate. A first load element is connected to the drain region of the first driver MOS transistor and the gate electrode of the second driver MOS transistor. A second load element is connected to the drain region of the second driver MOS transistor and the gate electrode of the first driver MOS transistor. A first transfer MOS transistor is formed at the surface, one of the source and drain regions of which is connected to the drain region of the first driver MOS transistor. Further, a second transfer MOS transistor is formed at the surface, one of the source and drain regions of which is connected to the drain region of the second driver MOS transistor. An inter-layer insulation film is formed on the first driver MOS transistor, the second driver MOS transistor, the first transfer MOS transistor and the second transfer MOS transistor.Type: GrantFiled: May 29, 1998Date of Patent: June 6, 2000Assignee: NEC CorporationInventor: Koji Deguchi

Patent number: 5598117Abstract: A MOS differential voltage-to-current converter circuit has first and second MOS transistors forming a differential pair and a resistor connected between the sources of the first and second MOS transistors. These first and second MOS transistors are connected to the sources of third and fourth MOS transistors, at respective sources. By biasing the third and fourth MOS transistors, with a constant current, differential input voltage is supplied to the gates of the third and fourth MOS transistors. The drain outputs of the third and fourth MOS transistors are respectively connected to first and second signal transmission circuits for transmitting the drain outputs to the gates of the first and second MOS transistors through the first and second signal transmission circuits. With taking the current flowing through the first and second MOS transistors as differential output, a voltage-to-current conversion characteristics not depending upon variable property of the MOS transistors can be obtained.Type: GrantFiled: July 1, 1994Date of Patent: January 28, 1997Assignee: NEC CorporationInventor: Koji Deguchi

Patent number: 5175482Abstract: A stepping motor control circuit (50) has a step circuit (51) and a track circuit (52). The track circuit has an up-down counter (1) including an offset circuit (11), and a decoder (2). The offset circuit speeds up the change over from the first digit to the second digit in an up-down counter, when a two-phase excitation system is selected for the stepping motor. The speed-up is by a half period, or so, in terms of the output of the first digit in the up-counting mode or down-counting mode. Therefore, in either of the up-counting or down-counting modes, the excitation output starts to change at the first clock pulse input after the counting direction has been changed. Thus, the operation speed of the control circuit can be improved. Also, the information on the completion of the track operation can be immediately sent to a host device.Type: GrantFiled: October 16, 1991Date of Patent: December 29, 1992Assignee: NEC CorporationInventor: Koji DeGuchi
