Title: Power converter
Inventor: KUROSAWA TOSHIAKI
IPC: H02M1/14
Filed: 1985-01-25
Abstract: PURPOSE:To reduce the harmonic wave current of a power source side by providing a circuit for absorbing the harmonic wave current generated by the operation of an AC/DC converter in parallel with an overvoltage absorber. CONSTITUTION:A compensator CP is used to suppress a harmonic wave current of a power source side generated by a resonance phenomenon. The relationship between the capacitor C and the inductance L of the compensator is selected to match the resonance frequency f0 of the inductance Lu of the power source and the capacitor Cu for absorbing an overvoltage, and when a resistor R is regulated optimally, the harmonic wave current of the frequency f0 can be absorbed. As a result, the harmonic wave current generated at the power source current can be suppressed by the resonance phenomenon of the inductances Lu-Lw of the power source side and the capacitors Cu-Cw for absorbing the overcurrent.

When the LTC is changed toward the dotted lines with the control signal externally, the signal from A reaches D and that from C gets to B to select the line of signals. In case of the line represented in solid lines, the leakage of the signal A-D is the sum of values determined with the isolation with LTCs21, 28, 27 and 23, 30, 25. Thus, the selection of the signal path can be made in high speed without using mechanical mechanism.

Title: Drop on-demand ink jet head
Inventor: UEMATSU RYOSUKE
IPC: B41J2/055
Filed: 1987-01-20
Abstract: PURPOSE:To inject an ink droplet different in a volume using one head without changing the flight speed of the ink droplet, by driving a piezoelectric element by the drive signal coinciding with the phase of a mode. CONSTITUTION:When a drive pulse is applied to each piezoelectric element, pressure inherent vibration of a tertiary mode is selectively excited in a pressure chamber. By this vibration, the pressure of a nozzle part also coincides with an inherent cycle to rise and fall and an ink droplet is formed. When a drive pulse having a phase coinciding with the half cycle of the inherent cycle r5 of a pentamery mode is applied to each piezoelectric element, the pressure inherent vibration of the pentamery mode is selectively excited in the pressure chamber. By this method, the ink droplet is also formed but, since the inherent cycle r5 of the pentamery mode is shorter than the inherent cycle r3 of the tertiary mode, the ink droplet having a volume smaller than that of the ink droplet formed in the tertiary mode is formed. By this method, the phase of the drive pulse applied to each piezoelectric element is controlled to make it possible to inject the ink droplet different in a volume.

Title: Recognition circuit for octet number of structural block
Inventor: TERADA TAKESHI
IPC: H04L7/08
Filed: 1994-02-04
Abstract: PURPOSE:To allow the circuit to immediately cope with a new configuration by counting continuously an octet clock number so as to recognize octet number of data for a structural block thereby eliminating the need for re-setting of the octet number even when the configuration of the structural block is revised. CONSTITUTION:A flip-flop FF 11 reads a 8-kHz frame clock C8K at an opposite phase of a serial clock CLK and an output of the FF 11 is differentiated at the opposite phase of the CLK to generate a negative polarity pulse corresponding to the rising of the C8K. On the other hand, a flip-flop 21 uses a 3-bit counter 23 to count the CLK at a leading of the C8K to provide an output of an octet clock formed by 1/8 frequency division from a Q2 output terminal. Then an 8-bit counter 31 counts the clock for one period of the clock C8K, then the result of count indicates binary notation of the octet number (n) of the data forming the structural block, the flip-flop 41 latches the data to obtain an 8-bit binary number expressing the value (n). Thus, even when the configuration of the structural block is revised, the octet number is recognized accordingly.
