Title: Electrostatic multi-ink jet head and electrostatic ink jet printer
Inventor: OHARA TERUMI
IPC: B41J2/06
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To facilitate size reduction and integration of an ejection electrode control circuit by arranging the control circuit between an ejection electrode bias power supply and an ejection power supply thereby lowering the withstanding voltage of the ejection electrode control circuit. SOLUTION: An election electrode control circuit 10 is arranged between an ejection electrode bias power supply Vb for aggregating charged coloring particles at an ink ejection opening and an ejection power supply Vh for flying the aggregated charged coloring particles. At the time of printing, the control circuit 10 applies an ejection electrode 7 with a bias voltage for aggregating charged coloring particles and then an ejection voltage corresponding to a print input signal is applied. The ejection voltage has same polarity as the charged coloring particles and the aggregated charged coloring particles flies from the ejection opening by Coulomb repellent force to form a dot on a recording medium 3. Since withstanding voltage of the ejection electrode control circuit can be lowered, size reduction and integration thereof can be facilitated.

Filed: 1994-06-02
Abstract: PURPOSE:To enable reading address and to unnecessitate error processing by repeating track jumps untill an optical pickup enters the range of a target address and extending the range of the target address for every time when the number of track jumps exceeds a specified number in the track searchings of an optical disk capable of a video reproducing. CONSTITUTION:This method is provided with a magneto-optical disk 1, an address decoder 4 decoding address data and an EFM modulation part and CRIC part 5 performing an EFM modulation to a signal to be recorded and performing a correcting operation to digital data read out from the magneto- optical disk 1. A track searching means calculates the range of the target address from a specified search address and calculates the number of tracks between the present position of a pickup 13 and a targeted address to perform track jumps. In the case where the optical pickup 13 is not placed on the range of the target address in spite of the execution of track jumps, whether the number of jumps exceeds, for example, 10 or not is checked and then in the case where the number does not exceed 10, jumps are repeated again. Then, jumps are repeated by extending the range of the target address.

Title: Phase locked loop
Inventor: YAMADA YOSHIFUMI
IPC: H03L7/14
Filed: 1983-08-08
Abstract: PURPOSE:To allow a phase locked loop to lock in phase again after a fixed period by interrupting and holding the output of a loop filter in the phase locked loop for the fixed period at the instantaneous out-of-phase. CONSTITUTION:Voltage due to the phase difference between the phase of an input signal 1 to the phase locked loop and the phase of an output from a voltage controlled oscillator 2 is outputted from a phase comparator 3. The output of the comparator 3 is applied to the oscillator 2 as a control voltage so that the phase difference is turned to zero by the loop filter 4. If the phase locked loop goes to out-of-phase, a switch 8 is turned off by a phase locking detecting part 9 to interrupt the output of the filter 4 and the output of the filter 4 is held for the fixed period (t) by a holding circuit 5. When the lock-off status is generated for the fixed period of instantaneously, the loop filter is held for the fixed period (t), so that the phase locking of the phase locked loop is restored again after the fixed period (t).
