Title: Method and device for plotting straight line
Inventor: TAKAHASHI YASUHIKO
IPC: G06T11/20
Filed: 1989-10-31
Abstract: PURPOSE:To improve plotting speed by deciding the number of dots to be generated on a next scan line from the accumulated result of the error from an ideal straight line and generating plural pieces of the dots at the same time on one scan line on the basis of the result of this. CONSTITUTION:The basic number N of the dots to be generated on one scan line is obtained by an arithmetic part 11 on the basis of the inclination of the ideal straight line to be generated to the scan line, and the error between the position of the generated dot and the ideal straight line is accumulated at every shift of the scan line, and from this accumulated result, it is decided whether the number (n) of the dots to be generated on the next scan line is either N or N+1, or either N or N-1. Then, the dots of the number corresponding to a decided result are generated at a time by the word width unit of a generating accumulator 12, and are stored in a bit map memory 3. Thus, the plotting speed can be improved.

Title: Sorter with finisher
Inventor: ISHIGURO KUNIAKI
IPC: B41J13/00
Filed: 1986-11-27
Abstract: PURPOSE:To make a staple function independently usable without disturbing a finish process at an on-line mode, by making an independent staple process at an off-line staple mode performable except during the finish process. CONSTITUTION:In the subroutine of an off-line staple process, when an off-line staple mode is selected, a staple process is performed upon making sure that a sheet is inset onto a staple tray 91 with the on or off of a sensor Se6. That is to say, the staple process only is independently executable with an off-line, and an independent staple process at the off-line is prohibited during a finish process, that is, it is possible only at time except during operation of the finish process, whereby if the sheet is inserted into the staple tray 91 during operation at the on-line by mistake, the staple process is in no case performed, thus the finish process at the on-line mode is not disturbed at all.

Abstract: PURPOSE:To improve the dispersibility of magnetic powder and durability by incorporating a vinyl chloride resin contg. a sulfo group and/or phospho group in the form of an alkali metal salt, urethane resin, nonmagnetic particles and lubricating agent into a magnetic layer and specifying the coefft. of dynamic friction. CONSTITUTION:The vinyl chloride resin contg. the sulfo and/or phospho group in the form of the alkali metal salt, the urethane resin, the nonmagnetic particles having >=5 Mohs' hardness and the lubricating agent are incorporated into the magnetic layer 3 and the coefft. of dynamic friction at 60-80 deg.C is specified to <=0.25. Since the vinyl chloride resin as a binder contains the sulfo group and/or phospho group in the form of the alkali metal salt, the viscosity of the magnetic coating compd. is low and the dispersibility of the magnetic powder is improved. The surface smoothness of the magnetic layer is thereby improved and the self-adhesiveness is considerably decreased. Since the urethane resin is used in combination in the magnetic layer, the durability is improved as well.

Filed: 1988-11-11
Abstract: PURPOSE:To easily detect a fault of an optical transmission line without error by providing an interference film filter to one end of an optical transmission line, sending an optical signal from other end and varying its wavelength so as to detect the level of the returned light. CONSTITUTION:A variable wavelength light source (OSC) 3, a photodetector (DET) 5 and an optical directional coupler 4 are connected to one end 1 of an optical transmission line being an optical fiber and the other end 2 connects to an interference film filter 6 and an optical transmitter (transmitter-receiver) 7. Then when an optical signal is outputted from a variable wavelength light source 3, the optical signal is sent to an optical transmission line 8 through the optical directional coupler 4 and the optical signal through the optical transmission line 8 enters one end 2, is radiated to the interference film filter 6 and the light with a wavelength not passing through the filter 6 is reflected in the optical transmission line 8 and returns to one end 1. The returned optical signal is branched by the optical directional coupler 4 and made incident in the photodetector 5. Thus, if no fault exists in the optical transmission line 8, the output level of the photodetector 5 is changed by varying the wavelength of the variable wavelength light source 3.
