IPC: H04N1/113
Filed: 1989-07-13
Abstract: PURPOSE:To adjust the fine frequency and to reduce the dispersion in the scanning start point by frequency-dividing a reference clock signal, generating plural pulse signals with the same frequency and different phases and selecting one of plural pulse signals as a picture scanning clock taking the synchronization with the scanning of the light beam. CONSTITUTION:A reference clock signal outputted from a reference clock signal generating circuit 10 is inputted to a pulse signal generating circuit 11, frequency-divided and plural pulse signals with the same frequency and different phases are generated and outputted. The plural pulse signals are inputted to a picture scanning clock selection circuit 12 and one of the plural pulse signals is selected as a picture scanning clock taking the synchronization of the scanning of the light beam corresponding to a synchronizing detection signal for periodic deflection of the light beam. Thus, a stable picture scanning clock is obtained against the fluctuation of the reference clock signal and the dispersion in the start point of the raster scanning of a face to be scanned due to the light beam is minimized and the optical scanning with high accuracy is attained.

Abstract: PURPOSE:To provide a system for producing the above bar-like synthetic resin matter having highly accurate outer diametral. CONSTITUTION:In a controller, at the component S1, the completion state of the preparation of automatic operation is judged. At the component S2, the rotational frequency (n) of a gear pump, the set value (a0) of the outer diameter of a bar-like matter, the number N of times of the measurement of its outer diameter and its take-off speed (v) are read. After the completion of the changing-over to automatic operation is judged at the component S3, the time T required from the delivery of the bar-like matter out of an extruder until its arrival at a measuring device is calculated at the component S4. After the elapse of the time T is judged at the component S5, the measurement of the outer diameter of the bar-like matter with a measuring device is carried out by counting the number of times N of measurement at the component S6 and repeating the measurement at the components S7 and S8 in order to obtain N measured values (a) of outer diameter. At the component 39, the average value of the measured values (a) is calculated. At the component S10, the average value and the set value (a0) of outer diameter are compared with each other. At the component S11, the corrected value of the rotational. frequency (n) of the gear pump is calculated so as to carry out the correction by decreasing the rotational frequency (n) of the gear pump when the average value of the measured values (a) is smaller than the set value (a0) of outer diameter.

IPC: C08L23/06
Filed: 1988-07-20
Abstract: PURPOSE: To make ribbon thinner than before available by employing polymer or copolymer blend of polyurethane and isotactic polypropylene as the substrate. CONSTITUTION: When drawing polymeric blend of polyurethane and isotactic polypropylene followed by stretching with cooled roll processing, what is much thinner than before can be obtained. Because the ribbon obtained after this satisfies standards of commercial products used for both purposes of printing and peeling correction and becomes much thinner, the cost can greatly be reduced. Obtained in consequence is a ribbon with good quality thinner than known ribbons. This can be used as substrate in the range of past thickness, and in this case, it is particularly fit for printing on coarse sheet as ribbon with large amount of ink transfer.
