Title: Device for measuring outside diameter
Inventor: IGUCHI TOSHIYUKI
IPC: G01B11/02
Filed: 1979-08-28
Abstract: PURPOSE: To simplify a measuring device and enhance its reliability, by using a lens to form an  image of rays of light from a diffusion plate illuminated by a light source and by using a solid  scanning element to read an equal magnification imge formed by a lens for a measured object  located on an image formation surface for the former image and by effecting prescribed calculation and processing to determine the outside diameter of the object.   
     CONSTITUTION: Light is irradiated from a light source 21 upon a diffusion plate 25 through a  reflector 22, a lens 23 and a filter 24. Diffused light from the plate 25 is formed into an image in a position (s) by a lens 26. The equal magnification image of a measured object 11 located in the  position (s) is formed on a solid scanning element 28 such as CCD by a lens 27. The solid scanning element 28 is scanned by a driver 29. The output signal of the element is processed by a  signal processor to determine the outside diameter of the object 11. The nonuniformity of the brilliance of the image formation surface (s) is compensated through a filter or a calculation circuit.  In that case, an optical output is changed into a binary code by an intermediate level (V max - V min )/2, and number N of O-level bits is counted and the pitch length l of a photoelement is multiplied by N to determine the outside diameter. Thereby, said procedure results in simplifying a  measuring device and enhancing its reliability.

Abstract: PURPOSE:To reduce the drop of potential of a developing part by using red and blue light sources for destaticizers respectively before and after transfer. CONSTITUTION:A photosensitive drum 1 is positively charged at a selenium- tellurium by a preelectrifier 2 and a latent image is formed by a laser beam 3 and developed by a developing device. The drum 1 is destaticized by the destaticizer 15 after cleaning based upon a cleaner 8. A red LED and a blue LED are used as the light sources of these destaticizers 14, 15, so that much carriers are generated on a carrier generating layer and a projection layer on the drum 1 respectively and electron holes are moved to the substrate side by the red and blue light based on the pairs of electrons and electron holes and efficiently neutrarized. Consequently, the drop of potential on the developing part is reduced over a long period and stable and excellent electrophotographing recording free from fogging or the like can be attained.

Title: Preventive and remedy for disorder caused by active oxygen in living body
Inventor: OONISHI HARUO
IPC: A61K38/44
Filed: 1979-08-27
Abstract: PURPOSE: To obtain the titled medicine effective to the radiation diseases and the side effects of a carcinostatic agent, adriamycin, by the use of human superoxide  dismutase as an effective component.   
     CONSTITUTION: Human superoxide dismutase (hereinafter called as haman SOD) purified from human blood or placenta, is used as an effective component. Oxygen existing in the living boy is usually triplet state ( 3 O 2 ), and it is said that when  singlet oxygen ( 1 O 2 ) or so-called active oxygen such as superoxide anion, etc. is  generated in the living body, the body is affected by various diseases (e.g. chronic  rhemarthritis, retinopathy of prematurity, radiation diseases, scenescence, hepatic  toxicity caused by catecholamine such as α- methyl DOPA, etc.). Since the  human SOD has a catalytic activity for the disproportionation decomposition of  superoxide anion into molecular oxygen and hydrogen peroxide, it is effective to  these diseases, and, as it is derived from the human, there is no side effect.
