The second line is affected by a parasitic capacitance at the moment when the scanning signals S3, S4 of the third and fourth lines rise in, for example, the horizontal period H1 and the pixel voltage P2 thereof is fluctuated. During this horizontal period H1, the scanning signals S2 (S1) are impressed in succession and a (TFT) which is the switching element is turned on and, therefore, the fluctuation-component of the pixel voltage is annihilated during this time. The horizontal period H1 ends and the scanning signals S1, S2 rise, by which the writing of the first and second lines is normally completed at target values V1, V2.

IPC: B41C1/00
Filed: 1990-09-14
Abstract: PURPOSE:To improve work efficiency by reading a plurality of manuscripts to be processed sequentially for processing and controlling a processing area with respect to size of a printing paper to be printed. CONSTITUTION:In a 1st process mode, character and image in a sheet of manuscript are read by scanning and character and image corresponding to the character and image in the one sheet of manuscript are processed by scanning on a sheet of original paper. In a 2nd process mode, characters and images in 2 or more manuscripts are read by scanning sequentially and characters and images corresponding to the characters and images in the manuscripts are processed by scanning sequentially in a sheet of original paper. In such a process printing method comprising the 1st and 2nd process modes, printing is performed on a printing paper having a predetermined dimension by using the processed original paper. In an execution of the 2nd process mode, when a processing is to be done by detecting size of a printing paper to be printed and by reading character and image of a preceding manuscript, the processing operation is interrupted once in a state that the original paper is scanned for a dimension corresponding to a size of 1/2 of the printing paper, and the scanning of the original paper and the processing operation are restarted in response to a start of the reading operation of a succeeding manuscript. Thus, even when the characters and images are deviated in a part on the manuscript, the printing can be performed efficiently.

Filed: 1994-10-12
Abstract: PURPOSE: To prevent substantial deviation from the true reference frequency of a base station by adjusting the reference frequency of the base station based on the reference frequencies of plural mobile stations. CONSTITUTION: Radio waves emitted by the plural mobile stations 1 present within the area of the present base station 2 are received, the difference of the respective reference frequencies of the stations 1 and 2 is obtained and the adjustment operation of the reference frequency of the station 2 2 is repeated every time the radio waves of the stations 1 are received so as to reduce a frequency difference by 1/N of the difference. Thus, the reference frequency of the station 2 is brought closer to the average value of the reference frequencies of the plural stations 1 stepwise.  In this case, a central control part 9 receives the radio waves of the plural stations 1 present within the area of the station 2, computes the difference of the reference frequencies of the stations 1 and 2 based on information obtained from an IF frequency counter 7 and performs correction stepwise in a frequency computing part 10 so as to reduce the difference.
