IPC: H04N1/04
Filed: 1990-09-14
Abstract: PURPOSE:To suppress the degree of ''blurring'' to the minimum by generating an information light obtained through a document only in a period in which a light source is turned on. CONSTITUTION:A light source 11 is provided so that its longitudinal. direction coincides with the width direction of a document, and a turn-on period is controlled by a light source control part 13. A CCD 12 is constituted by providing an optical signal. accumulating part 12a and a shift register 12b. The optical signal accumulating part 12a is provided with a photodiode group in the longitudinal direction. Also, each photodiode is constituted so as to input a reflected light reflected by a document 15 and to accumulate optical. signal charge corresponding to an image. The shift register 12b outputs a picture data signal based on an optical signal. transferred from the optical signal. accumulating part 12a. In such a way, ''blurring'' in image read can be reduced without shortening the optical signal accumulation time.

Title: Inverter
Inventor: NAKAMURA TAKASHI
IPC: H02P27/06
Filed: 1984-11-20
Abstract: PURPOSE:To prevent a rotary load from reducing its acceleration force at rising time by setting rated voltage and frequency characteristic lower than the voltage of V/f pattern in a frequency corresponding to the normal rotating speed. CONSTITUTION:In an inverter 1 of a motor 2 for driving a load such as a sewing machine 3, a motor 7 is driven by the output of the inverter 1 at constant V/f ratio the frequency corresponding to the normal speed of the machine 3, and the rated voltage/frequency characteristic of the motor is set to the voltage lower than the V/f pattern in the frequency corresponding to the normal speed. Thus, since the magnetic flux density increases in the amount corresponding to the voltage difference between the V/f pattern (solid line C) and the motor characteristic (broken line D), the output torque rises as the frequency increases. Accordingly, the rising characteristics of the machine 3 becomes efficient without reduction in the acceleration force.
