Title: Method and apparatus for detecting bubble in compressed-liquid discharging system
Inventor: SUTEFUAN ERU MAAKERU
IPC: G01N11/08
Filed: 1992-02-21
Abstract: PURPOSE: To detect a bubble if a fluid while discriminating from other pressure disturbance by filtering the pressure detection signal of a pressurized liquid thereby removing two signals lower than a predetermined reference level, a short duration signal and a long duration signal. CONSTITUTION: A pressure detection means 58 detects pressure drop of a pressurized fluid delivered through a nozzle 56 continuously to generate a signal 60 corresponding to the pressure varying with time. The signal 64 is amplified 61 and a a negligible waveform having extremely small amplitude is removed through an amplitude filter 62 thus delivering a signal 64 to a band-pass filter(BPF) 66. The BPF 66 compares positive and negative reference levels being set in a high-pass filter 66A and a low-pass filter 66B with the time interval between the intersection of respective waveforms and removes a short duration waveform or signal of abrupt variation not corresponding to the waveform of bubble and a long duration waveform or signal varying slowly through filtering.  An AND 66C delivers a signal 68 indicative of passage of the signal 64 through both filters thus indicating that a bubble is generated at the nozzle 56 or passed through the nozzle 56 by a bubble designation means 70.

Filed: 1988-02-19
Abstract: PURPOSE:To improve the using efficiency of a buffer memory by equipping an alternative clock generating circuit and a data abandoning means to abandon data addressing a line, for which a clock is disconnected in the buffer memory. CONSTITUTION:When a clock 18 from an outgoing line is disconnected, an alternative clock 21 is generated by an alternative clock generating circuit 20 with using the internal clock and outputted to a register 13. For the alternative clock 21, a logical sum is obtained with the clock 18 from the outgoing line in the inside of the register 13 and data to be accumulated by the register 13 are outputted samely as a normal time. Such a condition is recognized by a buffer control part 15 through a signal line 14 and data in a buffer memory 11 are outputted by normal operation hereafter. Accordingly, the data addressing the outgoing line, for which a trouble is generated and the clock is interrupted, are outputted without stopping in the buffer memory 11 and wholly wasted on an outgoing line 19. Thus, a buffer memory area to be used for the data addressing the trouble generating line is released and the using efficiency of the buffer memory is improved.

Title: Pattern detecting circuit
Inventor: OOHAMA MASAYUKI
IPC: G06F7/02
Filed: 1983-03-07
Abstract: PURPOSE:To detect a specific pattern with a small quantity of hardware regardless of length by providing one exclusive OR circuit, two FF circuits, specific pattern generating circuit, parallel-series converting circuit, and timing generating circuit. CONSTITUTION:When an input serial signal arrives at an input terminal IN, the exclusive OR circuit 3 makes a bit-by-bit comparison between the input signal and the signal of the specific pattern converted by the parallel-series converting circuit 5. When the comparison between the fianl bits is completed, the timing generating circuit 8 sends a latch signal to an FF7. The FF7 decides on whether the specific pattern is detected or not. An FF6 is reset by the output signal of the circuit 3 when a bit in dissident pattern is detected in the middle of the generation period of the specific pattern. In this case, the FF7 outputs zero to an output terminal OUT. When it is decided that the bit in coincident pattern is detected, 1 is outputted.
