Title: Reducing method for quantized noise
Inventor: UCHIKOSHI KOUJI
IPC: H03M1/66
Filed: 1981-10-12
Abstract: PURPOSE:To reduce effectively the quantized noise to the frequency of a low level and to simplify the increase of the number of changing bits, by compensating the analog voltage produced centering on a changing point based on the shorter one of the 1st and 2nd times of the sampling period of information. CONSTITUTION:The supplied digital signal Dn is compared with the signal Dn-1 obtained from a shift register 1 before sampling through a comparator 4. Then the signal, which does not change during the 1st time which is equal to an integer-fold value of the sampling period and then changed into the information which is different at the changing point, is detected by a detecting circuit 5 with the outputs Qa and Qb. This information is fed to a read-only memory ROM. Then the analog voltage of the shorter one of the 1st and 2nd times and produced centering on the changing point is compensated based on the shorter time and by an ROM9, a latching circuit 11, an ROM12, a compensated voltage generating circuit 14, etc. in case the different information has no change during the 2nd time which is equivalent to an integer-fold value of the sampling period. The output of a D/A converter 3 is compensated by a mixer circuit 15.

Title: Recording apparatus
Inventor: ONO TAKESHI
IPC: B41J2/355
Filed: 1988-07-01
Abstract: PURPOSE:To prevent the occurrence of white stripes at the time of recording of a first block by a method wherein image data are not recorded at a record timing accompanying at least first conveyance of recording paper, and corresponding 1-line recording of the image data is conducted at a subsequent record timing. CONSTITUTION:When a recording start instruction is received from CPU 102, a BUSY signal to a main control element 100 is turned to be '1' to prohibit a subsequent recording start instruction from the main control element 100. Next, a pointer PP to be recorded is set at '4'. This is made for the purpose of making record in the direction of sub-scanning with a density being rougher four times than the minimum record density by a recording element 110 so as to record one line of an image by four lines. Next, whether or not recording is skipped by high-speed conveyance of recording paper because of all the line data preceding by one being a white line, for instance, is checked up from whether a SKPF flag is ON or not. When it is not ON, a mechanism element 117 is driven to convey the recording paper for one step and recording for one line is executed. This recording operation is conducted by electrifying each of four divided blocks of a thermal head 115 for 0.6ms at the maximum, and therefore a time of about 2.4ms is required for recording one line.

Title: Driving circuit of picture tube
Inventor: SANEISHI YASUO
IPC: H04N9/64
Filed: 1982-09-20
Abstract: PURPOSE:To obtain the driving circuit of a picture tube which prevents deterioration of frequency characteristic, by reducing the value of the collector resistance of a transistor which supplies a collector output to the cathode or the grid of the picture tube. CONSTITUTION:When both horizontal retrace pulse and vertical retrace pulse do not exist, the output voltage of a constant-voltage circuit 2 which is determined by a constant-voltage diode Dz, a resistance R9, and a volume VR is applied to the base of a transistor Q2. Therefore, a voltage which is lower than that of the emitter of the transistor Q2 is outputted and a low voltage is applied to a cathode Ca. When the horizontal retrace pulse or the vertical retrace pulse exists, a pulse of a relatively high level is inputted into the base of the transistor Q2 and, therefore, a high voltage is applied to the cathode Ca. Consequently, the collector loss of another transistor Q1 is reduced and the value of the collector resistance can be reduced. Thus deterioration of frequency characteristic due to a stray capacity is prevented.

Title: Two-color electrophotographic recorder
Inventor: HIDA MASAYUKI
IPC: G03G15/04
Filed: 1979-12-18
Abstract: PURPOSE:To carry out sharp 2-color recording without mixing of 2-color toners on a photosensitive drum, by conducting formation of the first latent image and its development, and after those, formation of the second latent image and its development. CONSTITUTION:Photosensitive drum 5 is charged to potential VS with charger 17, and exposed 12, forming a latent image with potential VL of the exposed areas controlled to about 1/2 of VS. This image is reversely developed with black toner 20 having positive charge in the first developing device 13. Then, drum 5 is positively exposed with the second exposing means so as to render the potential of the exposed areas nearly VL. Drum 5 is positively developed in the second developing device 16 with red toner having negative charge. At that time, developing bias voltage VDB2 is kept somewhat higher than potential VL. Such a process permits a black and red toner image to be formed on drum 5 and sharp 2-color recording to be made without mixing of the 2-color toners.
