Title: Multi-color recording device
Inventor: TODA TOSHIO
IPC: G03G15/01
Filed: 1985-02-20
Abstract: PURPOSE:To obtain a color image having no color mixture even if the potential on a toner image of the 1st color which is already formed varies by varying and controlling the bias voltage value of the next development of the 2nd color according to the potential on the toner image of the 1st toner after electrostatic recharging. CONSTITUTION:A two-color recording device charges a photosensitive drum 1 electrostatically and uniformly by an initial charger 2, and the 1st exposure system 3 forms the 1st latent image, which is developed in the 1st color by the 1st developing device 4. Then, a recharger 5 charges the photosensitive drum again, the 2nd latent image is formed by the 2nd exposure system 6 and developed in the 2nd color by the 2nd developing device 7, and the toner images of the two colors are transferred and fixed at a time to obtain two-color record. Then, the potential on the toner image of the 1st color after the recharging is measured by a surface potential meter 21 and a control part 20 controls the developing bias variable power source 17 of the 2nd developing device 7 according to the potential so that the developing bias voltage of the 2nd color is invariably lower than the potential on the toner image of the 1st color.

Title: Slitting method
Inventor: KAGOO MASAJI
IPC: B23D33/00
Filed: 1989-02-13
Abstract: PURPOSE:To perform separating operation without causing damage to a metal strip when the metal strip is slitted by separating the slitted strip using slope changing rolls. CONSTITUTION:A metal strip 1 slitted into a strip 11 and a strip 12 by a slitter 2 passes through a deflector 3, then is separated by a first inclined roll 4 and a second inclined roll 5 so that only the strip 11 is raised, and is wound round a tension reel through a pinch roll 6. The distance between a lowest point of the roll 4 and a path line is maintained to be 10mm so that contact between the strip 11 and the strip 12 is prevented and the roll 4 contacts only the strip 11. Further, the distance from an upmost point of the roll 5 to the path line is maintained in the movable range of -10 to +190mm, the roll 5 contacts only the strip 12, and separation of the strips is thus promoted by the difference of elevation between the roll 5 and the roll 4 and the angle between them.

Title: Device and method for print control and storage medium stored with computer-readable program
Inventor: IKENO TOSHIHIKO
IPC: B41J5/30
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to shorten a host release time by limiting the start of data processing by a printing process means by a control means until a receiving buffer becomes full when a setting means sets a data reception priority mode. SOLUTION: The setting means 115 sets the data reception priority mode wherein data are received preferentially by the receiving buffer. When the data reception priority mode is set, the control means 111 limits the start of the data processing by the printing process means until the receiving buffer becomes full to store print information continuously. Thus, when the data reception priority mode is set, the control means 110 limits the start of the data processing by a printing process part 108 until the receiving buffer 105 becomes full, so the print information can be stored in the receiving buffer continuously in an idle state wherein no print information is processed, so that the host release time can be shortened.

Title: Strip monitoring device
Inventor: KAYA KAZUAKI
IPC: B65H26/02
Filed: 1985-02-21
Abstract: PURPOSE:To prevent a walk from taking place without any restriction from both environment and facilities by monitoring the running condition of a strip using an equivalent spring constant outputted from an arithmetic device where a computation is performed taking into consideration both the revolving speed of a drive motor and the output signal from a tension force detector. CONSTITUTION:A computation is performed by an arithmetic device 6 taking into consideration both the revolving speed Ni-Nk of roller 2i-2k and the output Fj from a tension force detector 3j for a roller 2j allowing the estimation Kij1 and KjK1 for an equivalent spring constant to be outputted. And when a walk takes place on the strip allowing the strip to be force out, the cross sectional areas (a) and (b) are decreased allowing the equivalent spring constant K to be decreased. Accordingly, when the equivalent spring constant is monitored, sudden change in the equivalent spring constant can be interpreted as an occurance of the walk enabling an warning alert to be sounded followed by the corrective action. While on the contrary, in case of a facility such as a continuous annealing furnace where the strip weaves among multiple rollers which are located up and down, a strip tension force computing means is arranged to each of rollers together with load cells allowing the equivalent spring constant to be computed. Then, based on the resultant, the tension force is computed so as to obtain the proper tension force preventing a possible walk from taking place.
