Title: Digital time base generating circuit and method of adjusting delay time between two output signals
Inventor: MEIBIN SHII SUWATSUPU
IPC: H03L7/22
Filed: 1990-08-31
Abstract: PURPOSE: To obtain a stable and adjustable time reference source by sending an output from a reference signal oscillator to 1st and 2nd phase locked loops(PLLs), applying respective output signals from the PLLs to 1st and 2nd coefficient frequency dividers and forming specific fine times between output reference signals outputted from these frequency dividers. CONSTITUTION: The 1st PLL 12 connected to the output of an oscillator 11 for outputting frequency f0 generates a signal of frequency f1 . A 1st coefficient frequency divider 19 connected to the output of the 1st PLL 12 sends a 1st reference signal, having a frequency equal to the frequency f0 to a line 33. On the other hand, the 2nd PLL 22 connected to the output of the oscillator 11 generates a signal of frequency f2 . A 2nd coefficient frequency divider 29 connected to the output of the 2nd PLL 22 outputs a reference signal, having frequency equal to the frequency f0 to a line 34. A time difference Δt exists between the 1st and 2nd reference signals. Consequently, reference time can be set up without using a calibrated delay line.

IPC: B41J2/175
Filed: 1990-08-30
Abstract: PURPOSE:To eliminate a fill-in so as to improve reliability by inputting a drive signal in response to image information to an energy working section, generating bubbles in ink, and attaching an ink flown from an ink surface caused by the working force due to instantaneous growth of the bubbles to a body to be recorded. CONSTITUTION:An ink 19 supplied to an ink supply chamber 3 from an ink supply pipe 2 passes through a fine slit 5 by the capillary phenomenon so as to fill the whole area of a comb-like flow passage 8 surrounded by barriers 7. When the ink 19 can not be supplied and held satisfactorily in the whole area of the flow passage 8 by only the capillary phenomenon, a water head difference may be used by adjusting heights of an ink tank and a record head 1. Thus, in a steady state where the height of an ink surface is adjusted so as to fill the whole area of the flow passage 8 with the ink 19 and to cover each heater 9 with the ink 19, bubbles are generated in the ink on heated heat generating layers 14 when each heat generating layer 14 is energized individually in response to image information. The ink 19 flies on the surfaces of the heaters 9 almost vertically due to the motive force of the bubbles.
