Title: Method for controlling electrostatic recording device
Inventor: NOZAKI HIROMI
IPC: G03G15/00
Filed: 1982-10-29
Abstract: PURPOSE:To reduce useless toner consumption, and to prevent early deterioration of performance of a cleaning device by detecting the density of a visible image formed at each of plural recording cycles, and controlling the process. CONSTITUTION:A charging device 2, a developing device 3, a transfer section 4, and a cleaning device 5 are arranged around a photoreceptor 1 of a rotary drum. A latent image is formed on the photoreceptor 1 by exposing it to a light image obtained from an original placed on an original platen 6 with an exposing device 8. A swinging lever 15 installed in a toner replenishing vessel 13 is moved to replenish the toner into a developer vessel 13. A light emitting diode 20 and a phototransistor 21 are arranged between the transfer section 4 and the cleaning device 5, and a reference density batch image 22 is formed to detect its reflected density. This density is compared using comparators C1-C3, and the results are fed to the ports P1-P3 of CPU. The CPU controls the interval for forming the image 22 intermittently in accordance with the density of the image 22. As a result, useless toner consumption can be reduced and deterioration of the device can be prevented.

Title: Heat transfer film and heat transferring method
Inventor: AKATA MASANORI
IPC: B41J31/00
Filed: 1986-08-18
Abstract: PURPOSE:To prepare a color image forming heat transfer film in which no back trapping phenomenon occurs thereby to improve color reproducibility by disposing a plurality of dye layer regions in a order of lower dye concentrations to be thermally transferred to a material to be transferred by a predetermined heat energy. CONSTITUTION:As a result that a plurality of dye layer regions having different hues made of dyes of different hues are continuously formed in a order of lower back trapping properties on a filmlike base, already heat transferred dye is less back trapped to the heat transfer film in case of a second thermal transfer, and the back trap is less further when thermally transferred thirdly or fourthly. Thus, color separation images of various hues which are faithful to color separation information of an original can be thermally transferred. Resultantly, a color image having very excellent color reproducibility can be formed. The dye layer regions formed in this manner have thicknesses of approx. 0.4-2.0.mum and the dyes in the dye layer is preferably in the amount of 10-60wt% of the weight of the dye layers.

Title: Picture processor
Inventor: YAMAGUCHI HIROSHI
IPC: H04N1/409
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To reduce the executing frequency of defective section verifying work. SOLUTION: A picture processor detects the defective section of a picture to be processed based on IR data after reading pictures recorded on a photographic film with respect to R, G, B, and IR(infrared region) (122) and, when a 'verification mode' is 'automatic selection of picture to be verified', fetches a selection criterion (126) and discriminates whether or not the picture is to be verified by collating the characteristic amount of the detected defective section with the selection criterion (128 and 130). When the picture is not to be verified ('No' in 130), the processor automatically corrects the defective section (132).  When the picture is to be verified ('Yes' in 130), the processor displays the picture before the defective section is corrected and, at the same time, clearly indicates the detected defective section (134) and informs an operator of the defective section or shifts to a manual correction mode in which the processor corrects the defective section in accordance with the instruction from the operator.

Filed: 1981-12-02
Abstract: PURPOSE:To eliminate the influence of noise and to simplify the constitution, by converting an optical image to an electric signal to detect the inclination of an analog waveform and making the analog output binary in an auto-focus camera or the like. CONSTITUTION:At the start of measurement, capacities C201 and C202 are discharged, and switching transistors TRs 191 and 192 are turned on by an input G. Since capacities C have no electric charge, a switching TR22 is turned on, and charging of capacities C201 and C202 is started. The light to photodiodes HD171 and HD172 is approximately proportional to charge currents of capacities C201 and C202. When the charge voltage of the capacity C201 exceeds the input voltage of an inverter INV211, the TR22 is turned off to break the charge of the capacity C202. The output of an inverter INV212 becomes ''0'' if the light to the photodiode HD172 is stronger than that to the photodiode HD171, and the output of the inverter INV212 becomes ''1'' if the light to the photodiode HD171 is stronger. The output of an output terminal OUT2 is monitored to discriminate the inclination of the output of a photodetector, and it is made binary.
