Title: Synchronizing method of image formation on photoreceptor
Inventor: KATSUHARA KATSUYOSHI
IPC: G03G15/30
Filed: 1982-06-25
Abstract: PURPOSE:To improve the accuracy of a synchronizing method of image formation, by setting preliminarily the number of pulses of a rotation detector till the carrying timing of a transferred paper and the time from the last pulse to the carrying timing of the transfer paper while keeping the optical start timing as a standard, to a copying machine as an inherent value. CONSTITUTION:Synchronous control of the carrying timing of transfer paper and the optical movement timing is performed after the transfer paper is carried to the position of a stop roll 12. The time from the start timing of an optical system to the carrying timing of the transferred paper is stored by the number of pulses N and a time T in this copying machine, and a timer is operated to measure a time till the first detecting time of pulse, and the new pulse counting number N' and a time T' from the first detecting time of pulse till the start timing of the transfer paper are sought on the basis of the time t, the number of pulses N, the time T and a pulse period t'. By this way, the accuracy is improved because intervals of detected pulses are compensated by the timer.

Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To enable movement of a camera for capturing a silhouette image in every direction while securing the jump edge of an objective surface to be inspected of an electronic component which is reflected on the silhouette image. SOLUTION: A camera 25 for capturing a silhouette image is set so that a main point P thereof is positioned on an extended surface L of the bottom face of a body 10 of an objective electronic component. If such a positional relation is maintained, the bottom face of the body 10 of the objective electronic component usually corresponds to the profile of the bottom end of the body 10 of the relevant electric component to be reflected on the silhouette image regardless of the direction in which the camera 25 is moved, while the surface of the bottom face of the body 10 of the objective electronic component is not reflected on the silhouette image. Accordingly, the jump edge of the bottom face of the body 10 of the objective electronic component does not become a roof edge or a smooth edge that is difficult to be detected stably.

Filed: 1990-04-26
Abstract: PURPOSE:To reduce the quantity of data to be stored and to attain the high speed conversion of data by storing previously the coefficients of each linear equation showing the nonlinear output data into a memory as the output data against the input data. CONSTITUTION:A function curve showing the nonlinear output data against the input data is approximately by a straight line connecting plural points corresponding to the inputs. Then (a) and (b) in an equation y = aX + b showing each straight line are previously stored in a memory as the output data against the input data.

Thus it is possible to reduce the conversion error and the number of data and furthermore to attain the high speed conversion of data with a reduced memory capacity and in a small number of program steps.
