Title: Bus system optical network system
Inventor: MOCHIZUKI MOTOMU
IPC: H04B10/278
Filed: 1988-03-01
Abstract: PURPOSE:To reduce the quantity of the optical fiber cable in use by employing two optical fiber cables for trunk transmission line and plural optical 2- branching couplers so as to build up the bus system optical network. CONSTITUTION:Each end of two optical fiber cables 1a, 1b for trunk transmis sion line are connected together and optical branching couplers 21a-21n, 22a-22n couple separately an output signal from communication controllers 4a-4n and an input signal to the communication controllers 4a-4n with the two optical fiber cables 1a, 1b. Since the optical signal outputted from a commu nication controller is branched into a direction A and a direction of the commu nication controllers 4a-4n in the optical 2-branching couplers 21a-21n con nected to the optical fiber cable 1a, the optical signal reaches all the communica tion controllers 4a-4n. That is, the optical network system of bus structure is built up by the optical fiber cables 1a, 1b only for the two trunk transmission lines. Thus, the quantity of the optical fibers in use in reduced.

Inventor: TERASHI KOSUKE
IPC: B41J19/18
Filed: 1986-03-06
Abstract: PURPOSE:To enable high-quality printing to be performed, by discriminating the distance from the current stop position of a carriage to a printing-starting position, and when the distance is not less than a predetermined length, moving the carriage under acceleration to the printing-starting position and thereafter moving the carriage from the printing-starting position at a constant velocity. CONSTITUTION:Before moving a carriage, it is judged whether there is any space between the current stop position A of a printing head 2 to a printing- starting position B. When the space is not less than apredetermined length, the carriage is started moving under acceleration from the current stop position A, and is then moved toward the printing-starting position B at a constant velocity. The carriage is decelerated in the course of this movement, and is momentarily stopped at a predetermined position A' on the upstream side of the printing-starting position B. From the momentary stop position A', the carriage is moved under acceleration toward the printing-starting position B, an acceleration ending time point for transition from acceleration into a constant-velosity movement being set in conformity with the printing-starting position, and then printing is started.
