Publication number: 20020041586Abstract: In serial transmission of a mixture of isochronous data and anisochronous data, communications thorough a transmission path with a high ratio of occurrence of transmission errors may disturb images during streaming reproduction and produce noise in sound. To solve this problem, the isochronous data that has not been successfully received is retransmitted using an anisochronous region. Thus, transmission error of the isochronous data can be reduced without impairment of isochronous characteristics of the data.Type: ApplicationFiled: October 10, 2001Publication date: April 11, 2002Inventors: Hiroshi Hayashino, Kazuhiro Ando, Shinichiro Ohmi, Yasuo Harada

Publication number: 20010008092Abstract: A starter for engines uses a leaf spring as a shift lever for advancing a pinion gear for engagement with a ring gear. The shift lever may be constructed with a plurality of layered leaf springs having respective front ends spaced apart one another to contact a one-way clutch at different positions. The shift lever may include a lever holder which has a low heat conductive member to minimize fatigue of the leaf spring. The leaf spring is initially loaded with a spring force.Type: ApplicationFiled: January 16, 2001Publication date: July 19, 2001Inventors: Mikio Saito, Kazuhiro Ando, Kiyokazu Haruno, Masahiro Katoh

Patent number: 6166448Abstract: In a starter for an engine, a magnet switch attracts a plunger by a magnetic force generated by a solenoid coil wound around a sleeve, so that a pinion fitted on an output shaft of a starter motor is driven by movement of the plunger to engage with an engine ring gear. The the plunger is pressed to contact tightly with the sleeve, whereby the relative movement between the plunger and the sleeve is restricted as long as the coil is held deenergized. The pressing may be attained by an inclined surface provided on the plunger or a flexture of a transmitting member which connects the plunger and a pinion.Type: GrantFiled: October 13, 1999Date of Patent: December 26, 2000Assignee: Denso CorporationInventors: Kazuhiro Ando, Tsutomu Shiga, Takeshi Araki

Patent number: 6114771Abstract: A resilient restricting member of a rotation restricting member which restricts a pinion moving body from rotating is accommodated in a frame of a restricting member holder under a flexed and loaded state so that the rotation restricting member has a sufficient rotation-restricting function as long as the rotary force of the pinion moving body does not exceed the load acting thereon at the time of engagement and restriction of rotation. When a pinion gear abuts the end face of a ring gear and the pinion moving body is restricted from moving forward, the entire rotary force of an output shaft acts on the pinion moving body. The resilient restricting member flexes further in the restricting member holder to allow rotation of the pinion moving body, thus enabling the pinion gear to mesh the ring gear. Thus, the rotary force of the output shaft is converted to the advancing force of the pinion moving body surely even when the spiraling of the helical spline is not so large.Type: GrantFiled: September 9, 1998Date of Patent: September 5, 2000Assignee: Denso CorporationInventors: Yoshito Takagi, Takeshi Araki, Kazuhiro Ando

Patent number: 6111872Abstract: A master station performing continuous operations is communicatively coupled with a plurality of remote stations performing intermittent transmission/receiving operations in constant cycles. Control units of the remote stations control radio communication devices to transmit synchronizing signals to the master station in constant cycles respectively. When the synchronizing signals are received from the remote stations, a control unit of the master station acquires information of corresponding intermittent receiving timing from a memory device, and controls a radio communication device to perform transmitting operations to the remote stations in coincidence with the intermittent receiving timing. Further, the control unit of the master station reads random number values from a random number generator in re-transmission of data, and shifts data transmission timing from original timing by time corresponding to the random number values.Type: GrantFiled: February 28, 1996Date of Patent: August 29, 2000Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takayuki Suematsu, Hiroyuki Imai, Kazuhiro Ando, Shinichiro Ohmi

Patent number: 6095164Abstract: In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a sheet of transfer paper, a CCD sensor detects an unremoved image formed by a stamp, additional writing, etc. and left on the transfer paper sheet after toner separating processing is performed with respect to the transfer paper sheet by a liquid-providing toner-separating unit. A discriminating mark such as a punch, a mark o, etc. is additionally provided to the transfer paper sheet having the detected unremoved image by a discriminating mark providing unit. The transfer paper sheet having the discriminating mark is automatically sorted by a sorting unit and is discharged onto a paper discharging tray. The toner removing apparatus may have an unrecognizing device for blotting the unremoved image such as a seal print, a signature, etc. on the transfer paper sheet.Type: GrantFiled: September 22, 1994Date of Patent: August 1, 2000Assignee: Ricoh Company, Ltd.Inventors: Masatoshi Saitoh, Kazuhiro Ando, Tadashi Saitoh, Youichi Asaba, Kiyoshi Tanikawa, Yoshiaki Miyashita, Satoshi Shinguryo, Shinichi Kuramoto, Sadao Takahashi, Yoshiyuki Kimura

Patent number: 6047758Abstract: In a method for repeatedly using an image holding member such as a sheet of paper, toner for an electronic photograph is constructed such that a maximum value of viscoelasticity of the toner shown by tan .delta. is equal to or smaller than 3 in the range of a heating temperature when the toner is heated and fixed to the image holding member. Such toner has sufficient elastic or cohesive force. Accordingly, when the toner is heated and fixed to the paper sheet, no excessive adhesive force is caused to such an extent that paper fibers of the paper sheet eat into the toner attached to the paper sheet. Accordingly, after an aqueous solution including a surfactant is supplied to the paper sheet by a liquid supplying unit, the toner is softened by heat from heating rollers so that the toner is attached to a surface of an offset belt.Type: GrantFiled: December 11, 1997Date of Patent: April 11, 2000Assignee: Ricoh Company, Ltd.Inventors: Shinichi Kuramoto, Youichi Asaba, Kiyoshi Tanikawa, Yoshiaki Miyashita, Satoshi Shinguryo, Sadao Takahashi, Yoshiyuki Kimura, Kazuhiro Ando, Tadashi Saitoh

Patent number: 5605777Abstract: A predetermined processing liquid is supplied by a liquid supplying unit to a sheet of transfer paper having a surface on which toner is stably attached. An adhesive state of the toner on the transfer paper sheet is changed to an unstable adhesive state. The processing liquid is constructed by water, aqueous solutions of a surfactant, a water-soluble polymer, etc. The transfer paper sheet including the processing liquid is fed to a toner separating unit. While the toner is heated and pressurized in the toner separating unit, the toner is attached to a separating roller having a surface on which the softened toner is easily attached. The toner separating unit then separates only the transfer paper sheet from the surface of the separating roller by a separating claw. The processing liquid is removed from the transfer paper sheet by heating the transfer paper sheet, etc. using a drying unit such that the transfer paper sheet can be reused for a copying machine, etc.Type: GrantFiled: November 27, 1995Date of Patent: February 25, 1997Assignee: Ricoh Company, Ltd.Inventors: Kazuhiro Ando, Yoshiaki Miyashita, Youichi Asaba, Kiyoshi Tanikawa, Satoshi Singuryo, Shinichi Kuramoto, Sadao Takahashi, Yoshiyuki Kimura, Tadashi Saito, Mitsuru Ohminato, Masaru Nakano, Eiichi Kawamura
