Abstract: PURPOSE:To decrease the number of operating channels of time division multi plex communication from 2 channels into one channel while keeping the reliabil ity of a duplicated communication line by adding a different address for each interface adaptor identification to a sending packet and using its identification address so as to discriminate each communication. CONSTITUTION:A packet sending circuit 1 in an equipment ST adds an identification address 1 to a data, when it comes from one communication line L1 and a time division multiplex TDM frame is sent to a time slot of a channel 1. When a data comes from other communication line L2, the packet transmission circuit 1 adds an identification address 2 to shape the packet form and the TDM frame is sent in the time slot of the channel 1. Thus, since which of the duplicated communication lines L1, L2 is to be used depends of the identification address added to the TDM frame, the number of operation channels is decreased from 2 to 1 channel.

Title: Ink jet head drive method
Inventor: YONEKUBO SHUJI
IPC: B41J2/045
Filed: 1990-01-23
Abstract: PURPOSE:To improve a printing quality by a method wherein an applied voltage signal directs an oscillator to start displacing in the departing direction from a nozzle opening, and the length of the pulse width thereof is determined to be a specific multiple of the length of the oscillation cycle of the oscillator. CONSTITUTION:Where an oscillating pulse width PW is a half of a cycle Tv, an ink drop speed 41 and an ink jet amount 42 are maximized. To obtain an ink jet amount as much as the ink jet amount 42 at the time of the pulse width PW of a half length of the cycle Tv when a pulse width PW of a drive voltage signal 17 is 3/5 - 4/5 times the cycle Tv in length, a drive voltage is increased. As a result, even if a nozzle gap which is a small gap between a nozzle opening and an oscillator 18 is so small that the oscillator 18 is subjected to a large reaction force through ink, the increased drive voltage allows the oscillator 18 to move against the reaction force at a sufficiently high displacing speed. Thus, an adequate ink drop speed can be obtained.
