Title: Ink jet recording device
Inventor: KOMAI HIROMICHI
IPC: B41J2/015
Filed: 1990-01-24
Abstract: PURPOSE:To supply a selected and optional amount of liquid to a liquid storage part and make possible an intermediate-tone recording by forming liquid droplets selectively from the groove of a beam member to the liquid storage part due to the movement of the beam member into a recording liquid. CONSTITUTION:A beam member 2 is provided extending to a recording liquid 4 in a liquid chamber 5 and a groove 3 is provided in the beam member 2. This groove 3 communicates with a liquid storage part 1 for forming liquid droplets for recording. A beam deforming device 11 is provided in the beam member 2. If a voltage pulse for forming a beam using the beam deforming device 11 is applied, the beam member 2 becomes deformed into the recording liquid, and the recording liquid 4 is guided into the liquid storage part 1 through the groove 3. The recording liquid of the liquid storage part is splashed by an electrostatic force generated by a recording voltage generation part 7 between opposed electrodes 8 provided on the rear of a recording sheet 9, and attaches to the recording sheet for recording. At that time, the beam member 2 is held in the recording liquid by increasing the width of a pulse generated by a voltage pulse generation part for deforming the beam 11. During this process, recording continues and thus an intermediate-tone visualization is possible.

Title: Coordinate input device
Inventor: SUZUKI NORIYUKI
IPC: G06F3/048
Filed: 1988-01-28
Abstract: PURPOSE:To delete the coordinates of wrong input points by counting backward the information corresponding to the vibration transmission time from the calculated coordinate value and checking the obtained information. CONSTITUTION:A coordinate input device consists of a vibration transmitting plate 8 which transmits the vibrations as elastic waves, the vibration sensors 6 containing the piezoelectric elements which detect the elastic waves, etc. The detection signals received from the sensors 6 are amplified by a preamplifying circuits 9-11 and supplied to the waveform detecting circuits 12-14 respectively. The circuits 12-14 detect the arrival timing of a prescribed waveform component through the waveform processing of each detection signal and latch the clocking information of a clocking counter 14 via latch circuits 15-17. This clocking information (the arriving time information between an input point and each sensor 6) is supplied to a controller via a microcomputer, etc., for calculation of the input coordinates. Then the comparison is carried out between the measured vibration transmission distance and the vibration transmission distance counted backward from the coordinate value. Thus the presence or absence of a significant difference is checked between both distances for decision and deletion of a wrong detection point.
