Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To provide an image reader in which overflow is prevented and no erroneous information is produced, while effectively utilizing maximally the dynamic range of a charge coupled device(CCD) by controlling a light storage time. SOLUTION: When an original with high glossiness is read and an incident luminous quantity is increased and a storage charge amount exceeds a reference amount, an output signal level detection means 17 detects a pixel whose signal level exceeds a reference value, and a storage time control means 18 generates a shutter signal or changes a generating timing of the shutter signal, so as to reduce the storage time. The detected result by the detection means 17 is reset for each line and when the detection means 17 detects the pixel again whose signal level is more than the reference value on a succeeding scanning line, the control means 18 changes the generating timing of the shutter signal so as to reduce the storage time further. A series of operations are repeated until the pixel whose signal level is the reference level or over is not longer detected.  Then a series of reading operations are conducted again with the storage time with which the pixel whose signal level is the reference level or over is not longer detected.

Title: Two main grooved rib type tread pattern with subsidiary grooves of superior resistance to gravel catching and gravel removing function
Inventor: SUMIKAWA YASUSHI
IPC: B60C11/03
Filed: 1981-02-03
Abstract: PURPOSE:To make a rib type tread with superior resistance to gravel catching and gravel removing function by arranging grooves in such a direction as their bottoms slant to the center side of a tire. CONSTITUTION:A tread part 1 is provided with a pair of main grooves 4 and subsidiary grooves 5. The center line l of a tire meridian profile of each subsidiary groove 5 slants to the normal n, drawn at an intersecting point between said center line and the tread, within the limits of 5-20 deg.. This not only makes it difficult for gravel on the road to be caught into the subsidiary grooves 5 but also causes those gravels caught into groove 5 to come off easily, due to strong resistance from the surface of walls of the grooves, thus realizing superior resistance to gravel catching and gravel removing function of said tread.

Title: Image reading device, its method and storage medium
Inventor: UTAGAWA TSUTOMU
IPC: H04N1/04
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To easily and surely eliminate wrong decisions of an ACS operation that is caused by the overshooting of a scan system by performing no ACS operation in a range, where the scan system is not stabilized at a prescribed speed and then performing the ACS operation after the area is stabilized at a prescribed speed. SOLUTION: When a copying operation is started, a 1st mirror unit starts a prescanning operation, and a counter 20101 counts the color pixels. Then an ACS operation is stopped after the count value of the counter 20101 is equal to the prescribed value. A decoder 4201 decodes a vertical scanning address outputted from a vertical scanning address counter 420 and compares this decoded address with a vertical scanning section signal VSYNC for outputting an ACS signal that rises with a delay equivalent to several lines. A CPU 417 refers to the color pixel value of the counter 20101 and sets a black/white image copying operation of a black/white original, when the color pixel value is smaller than 128. When this pixel value is larger than 128, the copying operation of a color image is set.  That is, the ACS operation will not be carried out in the range where a scan system is not stabilized at the prescribed speed of the 1st mirror unit.
