Title: Skewless searching circuit
Inventor: ONO MASAHARU
IPC: H04N5/93
Filed: 1985-11-11
Abstract: PURPOSE:To suppress the generation of skews by entering data based on a horizontal synchronizing signal obtained at the time of reproducing and extracting the data by a clock with the same frequency as that of a television synchronizing signal. CONSTITUTION:If a switch 4a is turned by a synchronizing signal W obtained at the time of reproducing and a position A is selected, information corresponding to a horizontal synchronizing signal period is stored in a shift register 6 connected to the A by a clock C. When a position B is selected, the information is stored in a shift register connected to the B. To read out the information, a switch 4b is turned by a signal R with the same frequency as that of the television horizontal synchronizing signal and the information is selected in the order stored in the shift registers 6, so that the horizontal synchronizing signal W in the reproducing system is synchronizing with the signal R for the selection of reading. The generation of skews can be suppressed by selecting the signal R as the same one as the horizontal synchronizing signal of the television.

Filed: 1988-10-06
Abstract: PURPOSE:To read the light and shade of an image faithfully even when the quantity of light emission of an illumination light source varies periodically by synchronizing the storage period of a photoelectric converting element with the period of the driving signal for the light source for original illumination. CONSTITUTION:The storage period signal which determines the storage time of the photoelectric converting element of a CCD chip 103 and the light quantity driving signal which makes the EL light source 101 emit light are generated by a signal generator 105 and inputted to the CCD chip 103 and EL light source 101 respectively. The signal generator 105 consists of a storage period signal generation part 105a and a light source driving signal generation part 105b and the storage period signal and light source driving signal are obtained based upon a clock signal 201 required to drive the photoelectric converting element. The storage period of the photoelectric converting element 103 and the period of the driving signal for the light source 101 for original illumination are synchronized with each other, so the integral value of the quantity of light in each storage time of the light source which emits light with the driving signal can be made constant. Consequently, the light and shade of the image can be read faithfully even when the quantity of light emission of the illumination light source varies periodically.

Title: Method for driving dot printing head
Inventor: TANUMA JIRO
IPC: B41J2/295
Filed: 1987-10-08
Abstract: PURPOSE:To enable dot pins to be driven at the minimum energy without catch of dot pins on a ribbon, by detecting the moment when the tip of a dot pin reaches printing paper for every dot pin, and by independently controlling the timing for each dot pin to return to the origin. CONSTITUTION:A detection board 45 is fitted with a piezoelectric element at a position nearly above an end of armature 37 opposite to the end where dot pins are secured. When dot pins 38 impinge on the printing paper, the piezoelement emits output A. When output C resulting from comparison with it is applied to flip flop 74 LS107, this element is reset by drive signal D and emits output E showing low level to high level. When the output of an impact detection circuit outputted on the reaching of dot pins to the printing paper shows low level, coil current flows. Therefore, the timing for dot pins to return to the origin is controlled for every dot pin, and the catch of pins on the ribbon can be eliminated. As the result, power necessary pin drive can be reduced as much as possible.
