Title: Image display device
Inventor: SANO TAKESHI
IPC: G09G5/00
Filed: 1994-12-09
Abstract: PURPOSE: To automatically generate the best sampling clock for the sampling of a video signal. CONSTITUTION: Image information in specific pattern for clock generation is stored in a memory 4, and prior to a video signal that a video output device 2 generates, the same video signal for clock generation as it is outputted from the video output device 2. A clock frequency control circuit 9 calculates the number of dots in one horizontal scanning period of the output video signal of the video output device 2 and a clock generating circuit 7 is controlled according to the number of dots to generate the sampling clock equal to the dot clock frequency of the video signal. This sampling clock has its phase adjusted by a clock phase varying circuit 6 and a sampling circuit 5 samples the video signal.  Then a clock phase control circuit 8 compares the patterns of the image part of the video signal for clock generation and the image information for clock generation in the memory 4 with each other and the clock phase varying circuit 6 controls the phase adjustment quantity.

Filed: 1988-12-02
Abstract: PURPOSE:To limit a current flowing in preamplifiers and to reduce a power- supply current at operating time by operating only a preamplifier connected to a selected memory array block and making the other preamplifiers into a non-operating state. CONSTITUTION:The data of memory array blocks 1-4 are inputted to respectively connected preamplifiers 5-8, passes through output control circuits 9-12, and outputted to an output terminal 17. Further, signals 13-16 to select the data of the blocks 1-4 to be outputted are inputted to the control circuits 9-12 and also inputted to the preamplifiers 5-8. Thus, while the preamplifiers connected to the blocks not to be selected never operate, the current flows only in the preamplifier connected to the selected block. Consequently, the power-supply current at the operating time can be reduced.

Title: Discharge lamp lighting device
Inventor: SHIOMI TSUTOMU
IPC: H05B41/24
Filed: 1989-11-27
Abstract: PURPOSE:To prevent generation of leading phase mode by means of the half wave discharging condition immediately after discharge is started, and enable quick transfer to the all-wave discharge condition by controlling the operating frequency of a switching element so as to transfer gradually from the frequency at no load to the frequency at lighting up when the start of discharging of a discharge lamp is detected. CONSTITUTION:When the start of discharging of a discharge lamp RL is detected, the operating frequencies of switching elements Q1, Q2 are so controlled as to shift gradually from the frequency f1 at no load to the frequency f2 at lighting up. This process prevents generation of the leading phase mode by means of the half wave discharging condition immediately after start of discharge, and the frequency f2 at lighting up is approached as the half-wave discharging condition approaches the all-wave discharging condition, thus the current flowing through a discharge lamp RL is increased and transfer to the all-wave discharging condition can be accomplished quickly.
