Title: Head driver for electrostatic ink jet printer
Inventor: TAKEMOTO HITOSHI
IPC: B41J2/205
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To suppress complication of circuitry incident to increase in the number of jet electrodes or the gray level. SOLUTION: The head driver 10 comprises a head control section 12 and a pulse width generating section 14. The head control section 12 converts a gray level data received from a host unit into the number of unit pulses for each jet electrode 106 and outputs presence/absence of unit pulse for all jet electrodes 106 in the order of the unit pulse. Every time when the presence/ absence of unit pulse is received from the head control section 12, the pulse width generating section 14 applies a voltage of specified pulse width to a jet electrode 106 where the unit pulse is present. Since increase in the number of jet electrodes or the gray level can be dealt with by increasing the number of unit pulse, complication of circuitry can be suppressed.

Title: Test method and its device for logic circuit
Inventor: TOKUYAMA SABUROU
IPC: G06F11/00
Filed: 1979-03-02
Abstract: PURPOSE: To reduce the test time as well as enhance the test efficiency by delivering the timing signal in switching based on the output expected logic value and then giving the comparison with the signal timing between the output of the tested logic circuit and the output expected logic value.  
     CONSTITUTION: Both output signal (c) of the voltage comparator and output expected logic pattern (d) are supplied to exclusive logic sum circuit 5, and output signal (e) of circuit 5 is supplied to D-type FF circuit 6. Decision timing signal (f) is applied to the clock terminal of circuit 6, and the logic value of signal (e) is decided by the timing of signal (f). For signal (f), the 1st and 2nd decision timing signals f 1  and f 2  corresponding to logic value "1" and "0" of output expected logic pattern (a) are delivered in switching through switch circuit 7. Thus signal f 1  is delivered in case the output expected logic value is "1", and signal f 2  is delivered in the case of "0" each.

Title: Digital/analog converter
Inventor: SUGANO HIROSHI
IPC: H03M1/66
Filed: 1987-02-04
Abstract: PURPOSE:To reduce distortion at the time of outputting a small signal by constituting an digital/analog converter with a constant adder based upon digital operation, an overflow limiter for restricting a maximum value based on a carrier output, a D/A converter, and a BPF. CONSTITUTION:The constant adder 2 adds a DC offset to a digital signal inputted from an input terminal 1. Since the polarity of a D/A converted signal is inversed when the added digital signal exceeds the peak value of the D/A converter 4, the digital signal exceeding the peak value is replaced by the overflow limiter 3 based on a carry signal 2b outputted at the time of exceeding the peak value. Since a signal less than an offset does not cross the bipolar zero point of the converter 4 at the time of converting the output of the limiter 3 by the converter 4, large distortion is not generated. Since the BPF 5 removes the added DC offset, an analog signal reduced at its distortion can be obtained from an output terminal 1.
