Title: Picture reader
Inventor: TAKENAKA YOICHI
IPC: G16H10/60
Filed: 1984-07-16
Abstract: PURPOSE:To read out effective picture information over a wide density range by changing the quantity of incident light in stages in accordance with the dynamic range of a photodetector system, dividing the picture information into proper density areas to read out the information and then synthesizing the divided pictures. CONSTITUTION:Optical beam scanning is adjusted so as to be executed twice during the sending of one picture element width of a film 9 and low density incident light and high density incident light are held in the 1st and 2nd scanning respectively. In each scanning, light corresponding to the density of a film is inputted to a photoelectric vonverter 12 and converted into an electric signal, which is logarithmically amplified, inverted and inputted to an A/D converter 15. The output of the converter 15 is switched by a switch 16 and stored in a low or high density data buffer 17 or 18. The output of the buffer 17 is compared with a constant by a comparator 21 and switched by a switch 23 to select data in each picture element. The value of low-density incident light can be calculated by adding a constant A corresponding to the difference between low density and high density to high-density data. Thus, effective picture information can be read out over a wide density range.

Abstract: PURPOSE: To improve self-lubrication and anti-abrasion, and to sharply reduce a leaking amount of sealed fluids, by thermal-compression-molding the compound mixed in a given ratio with graphite powder, plastic resin binder and boron nitride powder.  
     CONSTITUTION: Graphite powder ranging from 55 to 70 weighing percent, plastic resin binder from 25 to 40 weighing percent and boron nitride powder from 2 to 15 weighing percent are mixed and are molded under a thermal compression method. The performance can further be improved by compound-adding silicon dioxide and a silica powder by 2 to 15 percent of either or both of them togetherwith the boron nitride powder. And thus, the determining results of an abrasion efficiency, a heating temperature and a specific abrasion amount show an extremely more excellent value in the part material made in such a manner as described above than in traditional one. Self-lubrication and antiabrasion can be improved eminently, and a sliding surface can also be free from roughening. A high sealing performance can thus be maintained.
