Title: Video information unit and sampling point optimizing circuit
Inventor: IMAOKA REN
IPC: H04N19/00
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To obtain an optimum sampling point of a video signal automatically. SOLUTION: A switch 4 of this unit is thrown to the position of a memory 3 with a delay of one frame and a delay in a delay circuit 10 is changed by dt each within a range of a dot clock period of an input video signal and an A/D converter 2 applies A/D conversion to the input video signal based on a sampling clock from the delay circuit 10. Every time the delay of the delay circuit 10 is varied by dt each, a comparator 6 of a correlation device 5 compares input digital video signal with an output digital video signal of the memory 3 and a counter 7 counts an output of the comparator 6 being the number of times of coincidence between both the video signals. The count indicates autocorrelation value and a microcomputer 11 detects a change point from a string of the autocorrelation for each delay of the delay circuit 10 and uses a sampling clock at a delay of the delay circuit 10 with respect to a median of the two change points as a sampling clock with an optimum sampling point.

Abstract: PURPOSE:To reduce the dispersion in performance by providing a fluid circuit and a magnetic circuit at the upper and lower parts of a straight line connecting electrodes, and providing straightening vanes at the upstream side and the downstream side of a coil case and a coil scale stopper. CONSTITUTION:Plannar straightening vanes 24 and 25 are provided on the upstream side and the downstream side of a coil case 20 and a coil case stopper 21.

Abstract: PURPOSE:To display the reception frequency correctly, by displaying the reference singnal frequency of phase locked loop through the display corresponding from the value carrying over the frequency dividing ratio control data to the magnification of multiplication circuit subtracting the data before carrying. CONSTITUTION:Since the channel space of intermediate broadcast electromagnetic waves is 9kHz, the frequency of the reference oscillator 245 of the PLL corcuit 24 of intermediate wave broadcast reception is taken as 9kHz. The output of the oscillator 29 according to the reception frequency is counted at the counter 28 to produce the frequency dividing control data, this is inputted to the programmable frequency divider 243, and the output and 9kHz are in phase comparison 244 to perform PLL operation. Further, the phase control data of the output of the counter 28 is inputted to the multiplication circuit 30 of 9 times. The circuit 30 constitutes the multiplication circuit of 9 times by subtracting original data from the number of carrying of the input data by one digit, i.e., the numeral of ten times, and this output is inputted to the display circuit 31. Thus, the display of display circuit is correctly corresponded to the frequency from the voltage controlled oscillator 241 and the frequency diveding ratio can be reduced to increase the nature of PLL.

IPC: F02B3/06
Filed: 1979-09-28
Abstract: An air compression direct-injection internal combustion engine having a combustion chamber shaped as a body of rotation arranged in a piston is adapted so that in use a rotational motion is imparted to inflowing combustion air, and at upper engine speeds fuel is deposited, by means of a needle nozzle with controllable cross-section, partly in the form of a film on the wall of the combustion space in the direction of the air motion, whereas during idling and at lower engine speeds and loads direct mixing with the combustion air occurs, the fuel injection pressure at the nozzle bore and thus the speed of the fuel jet being maintained constant or substantially constant over the entire operating range of the engine. The speed of the fuel jet is adjusted so that at nominal rotary speed of the engine it is substantially equal to the swirl speed of the combustion air in the vicinity of the fuel jet, and as the rotary speed decreases the speed of the combustion air is reduced substantially to form a speed difference causing friction between air and fuel. The diameter of the injection orifice is selected in accordance with the ratio of engine R.P.M. between idle and nominal speed.

Abstract: PURPOSE:To surely obtain the error log by constituting this system so that in the case a command error is detected, a microprocessor detects an idle time and executes write of the error log to a flexible disk device in the course of on-line. CONSTITUTION:When a command error is detected, a microprocessor 4 detects the case there is no command processing to a host 1 and a peripheral equipment 3 and starts a log write processing. When an error log is stored in a memory part 7, the processor 4 reads out a state status of a diagnostic processor 6 through a line 40. Subsequently, unless the processor 6 is writing a log to a flexible disk 5, a log write instruction is issued and the error log is read out of the memory part 7 through a line 30 and transferred to the processor 6. The processor 6 starts to write the error log from the processor 4 to the disk 5 through a line 50. When write is ended, the log write end is displayed on the state status.

Abstract: PURPOSE:To print a high-quality reduced character with a simple construction, by providing a mechanism horizontally inclining a printing head or a head holder to vary under control a lengthwise dot pitch. CONSTITUTION:Dots 3-5 carry out a printing with heating elements etc. in a thermal head. In a printing head 2, (n) pieces of printing dots are aligned lengthwise in a line. A dot pitch varying control mechanism consists of a head holder 1, a rotating shaft 6 for inclining the head holder 1, and a gear 7 for transmitting a power for inclination. When a dot pitch P of the printing head 2 is not inclined, the pitch P is used as a lengthwise dot pitch in printing. When it is inclined by an angle of theta, a lengthwise dot pitch 10 in printing is cos theta-times the dot pitch P of the printing head. At this time, a lateral deviation is generated by the distance of P X sintheta, but a dot string can be printed vertically without inclination by shifting an electrical energy applying timing to each dot by the amount off P X sin theta/v (v represents the horizontally scanning speed of the printing head).
