Title: Data for high-speed data transfer between lsi
Inventor: INAGAWA TAKASHI
IPC: G06F1/10
Filed: 1995-03-09
Abstract: PURPOSE: To operate with a clock frequency of higher speed by means or the same CMOS process. CONSTITUTION: In a system consisting of first and second LSIs 1 and 2 and a clock supply circuit 3 supplying a clock for these LSIs 1 and 2, signal transfer from first LSI 1 to second LSI 2 is executed by the synchronizing transfer of the latency of 1.5-clock and that from second LSI 2 to first LSI 1 is executed by the synchronizing transfer of the latency of 1.5 clock. In a system where the synchronizing transfer of the signal between LSIs 1 and 2 determines the upper limit of the frequency of a system clock, the upper limit of the frequency of the system clock can be improved to be 1.5-fold through the use of this method.

Title: Method and device for image processing using fm signal
Inventor: SHINOHARA KOICHIRO
IPC: H04N1/407
Filed: 1994-03-22
Abstract: PURPOSE:To attain image processing with excellent sharpness, gradation and granuality and a wide dynamic range by scanning a photosensing body through the comparison between a received image signal and a reference signal frequency-modulated depending on a characteristic quantity of the image signal and lighting or extinguishing a laser beam used for exposition. CONSTITUTION:A received image signal is converted into an analog signal whose amplitude is in a range of -1V to 1V by a D/A converter of a comparator circuit 15 and a comparator of the comparator circuit 15 compares the analog signal with an input (r) from an FM modulation circuit 32. Since an image output device 16 in this case adopts the image writing system making print to a lighting section of a laser, the comparator provides an output of a lighting signal only when the image signal is larger than the input (r) from the FM modulation circuit 32. Thus, a low frequency output is obtained with a low input contrast where gradation is continuously changed and a high frequency output is obtained with a high input contrast such as a character respectively.

Title: Reactive power compensating device
Inventor: NISHIKAWA TADASHI
IPC: H02J3/18
Filed: 1986-03-11
Abstract: PURPOSE:To attain the immediate supply of the gate signal at the time of reapplication by using a means which applied the first gate signal to a thyristor at a time point when the A-K voltage of the thyristor is changed to a forward state from a reverse state and a means which always supplied the gate signal at a zero-cross point of the power supply voltage. CONSTITUTION:In case a capacitor application command is outputted when the capacitor voltage VC is higher than the peak level of the power supply voltage VRS, no zero-cross point is outputted through the A-K forward and reverse voltage detectors 4-1 and 4-2 of a thyristor. Thus the 1-shot multiplex circuits 10-1 and 10-2 output no output. While the signals received from a voltage transformer 6 and a zero-point detector 7 are always outputted at a zero point of the power supply voltage. Thus an AND circuit 12-1 is set up with those signals received from the transformer 6 and the detector 7 and a capacitor application command. Then a thyristor Th1 has ignition to start supply to the capacitor current. The zero point of the power supply voltage is detected in such a way for supply of the gate signal. As a result, the holding time is reduced less than a single cycle.
