Title: Current generating device
Inventor: IKEDA MASAHARU
IPC: H03F3/34
Filed: 1984-03-13
Abstract: PURPOSE:To allow the titled generator from being hardly affected against the fluctuation of a power supply and variation of hfe of a transistor (TR) by providing a negative feedback system to compensate an output of a current mirror circuit. CONSTITUTION:TRs 13, 14 and 16 form the current mirror circuit. Suppose that the collector current of the TR16 is increased, the collector current of the TRs 13, 14 is increased so as to increase a base potential V1 of TRs 11, 12. Thus, the collector current of the TR12 is increased, a base current of the TR15 is decreased and then the collector current is decreased. That is, the system forms a negative feedback. Since the output of the current mirror circuit is compensated by the negative feedback system, the effect due to the variation in the hfe is decreased. The effect due to the fluctuation of the power supply voltage is decreased similarly. Thus, the generator is hardly affected by the fluctuation of the power supply voltage and the variation in the hfe of the TRs.

IPC: G09G3/36
Filed: 1989-02-28
Abstract: PURPOSE:To cancel a DC level and to shorten the time required for a display by applying necessary initializing voltages which differ in polarity in initialization periods of 1st and 2nd fields. CONSTITUTION:The voltage which rises above the threshold value of liquid crystal is applied in the initialization period of the 1st field to initialize the liquid crystal and in a display selection period following it, the voltage which rises in the opposite direction from that in the initialization period is applied to select a liquid crystal display state corresponding to the applied voltage. In the following initialization period of the 2nd field, the voltage which has the opposite polarity from that of the applied voltage of the 1st field and falls below the threshold value of the liquid crystal is applied to initialize the liquid crystal and then a display state is selected with the applied voltage which falls in the opposite direction from that in the initialization period. The polarities of the applied voltages are made opposite between the 1st and 2nd fields to make the DC levels of the 1st and 2nd fields cancel each other, and a display is made at one field period, so that the time required for the display is shortened.

Title: Liquid crystal display device and driving method therefor
Inventor: ANZAI NORIO
IPC: G02F1/133
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To cancel the influence of the deviation from an ideal value of an effective voltage by induction from data signals to scanning signals and to reduce crosstalk for damaging display quality by contriving the application timing of a data signal voltage. SOLUTION: Gradation display data composed of plural bits are received and a voltage corresponding to display data signals decided by the scanning signals for the respective bits is applied only for a certain period by being weighted for the respective bits during one horizontal scanning period and differentiating the application timing at each or at least one or more column electrodes. That is, by turning the data signal voltages to different signals C1N and C2N though display data on the column electrode and the display data on the different column electrode are the same, the timing of the change of a waveform and the direction of the change of the waveform become different.  Thus, the waveform distortion of a scanning voltage caused by being induced from the data voltage is relatively small and dispersed timewise and the deviation from an ideal waveform without the waveform distortion at all of the actually applied voltage waveform becomes small.

IPC: B41J19/18
Filed: 1990-02-28
Abstract: PURPOSE:To eliminate the generation of disturbance in printing and improve the quality of the printing by a method wherein the movement of a first pin array is controlled so that a distance between the first pin array and the character string becomes equal to the accelerating distance of a printing head, which is necessary for the printing with a given speed, while the movement of a second pin array is also controlled in the same manner. CONSTITUTION:When printing is effected in two times by the left and right arrays of pins, a microprocessor 1 controls a side feeding mechanism 4 and moves a printing head 5 so that a distance CPLL between the left side pin array and the left end of a character string becomes equal to the minimum accelerating distance L of a printing head, which is necessary for printing the string with a given speed, and a character string is printed by only the left side pin array. Next, the printing head 5 is returned to the upper part of a left end side sensor 6 and the printing head 5 is moved so that a distance CPLR between the right side pin array and the left end of the array of letters becomes equal to the minimum accelerating distance L. Thereafter, the printing is effected from left to right by only right side pin array. As a result, a distance (lL) between the left side pin array immediately before printing and an arbitrary point P1 in the character A string becomes equal to another distance (lR) between the right side pin array and the point P1 becomes equal whereby no time difference is generated in the printing at the left and right sides of the point P1.

Title: Gradation image recording
Inventor: KIYOJIRI HIDEAKI
IPC: H04N1/40
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To contrive the way to reproduce a high-resolution image in the high grade and linear gradation mode by distributing the density of a pixel into dots at a previously set rate corresponding to each of different density levels and always making a dot indicating a maximum density identical in each of the pixels at least, of an intermediate tone area. SOLUTION: The density of a single pixel is distributed to a right and a left dot using only a coordinate present in the left upper area of a graph. Consequently, the contrast balance of the density of the right and the left dot is identical through the entire pixels, so that the pixels are oriented in their well coordinated direction. Many curves for reproducing the density of each of the pixels by distributing it to the right and the left dot are present, and their optimal curves are selected depending upon the type of a recording paper and the shape of a thermal head. Thus there are no possibilities that a space between the adjacent pixels might be lost, because the orientation of the pixels is well coordinated, and it is possible to reproduce the linear gradation of an image.
