Title: Picture reader, picture reading method and recording medium
Inventor: TODA YOSHIZO
IPC: H04N1/19
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To execute appropriate original reading even if a prescanning operation is not executed at every reading operation through the use of a white board. SOLUTION: An AGC circuit 6 controlling the gain of the picture signal of an original, which is read by an image sensor 2, is constituted so that it can write a fixed gain value that is set at the time of reading an initial amplification gain value and at the time of reading the original after tracing control. The secular output deterioration of the image sensor 2 by original reading is judged according to integrating reading time. The fixed gain value of an AGC circuit 5 is decided and set based on the judged result. Thus, it is not necessary to trace/control the amplification gain value at every time at the time of subsequent original reading when an initial amplification gain value against white reference is once registered prior to original reading.

Abstract: PURPOSE:To enable a low reaction region and a high reaction region to be distinctly discriminated from each other in a dash pot having a buffer orifice in its cylinder wall by providing a notch to the front brim of a piston that supports a piston ring. CONSTITUTION:A buffer orifice 15 is provided on the circumference of a cylinder 5 in order to promote the discharge of the fluid from a high pressure chamber 11 and to prevent the large reaction, which is caused by an orifice 14 at the same time when a piston 6 starts operating, from occurring.
