Title: Method and apparatus for detecting defective sealing of drug pack
Inventor: KINOSHITA HAJIME
IPC: G01N21/93
Filed: 1990-03-05
Abstract: PURPOSE:To detect defective sealing even if there is waviness on the surface of wrapping film by projecting light on the surface of the aluminum wrapping film of a drug pack, comparing the amount of the reflected light with a regular reference, and judging the defective sealing. CONSTITUTION:A drug pack 1 in a continuous-sheet shape is moved with a conveying body 11. Light is projected on the surface of the aluminum wrapping film of the drug pack 1 from a light projector 12. Mesh-shaped sealing grooves having the specified depth are formed in the surface of the seal when the thermally bonded seal of the wrapping film is normal. Therefore the light is irregularily reflected from the grooves. Thus the amount of the light inputted into a screen 16 is reduced. When the seal bonding is defective, the seal grooves are not formed, and the irregular reflection does not occur. Therefore, the amount of the incident light into the screen 16 is increased. Then, the amount of the reflected light is compared with a specified value with a light receiving device 17, and the pass or fail is discriminated. In this way, the defective sealing can be positively detected even if there is waviness on the surface of the wrapping film.

Title: Electrophotographic sensitive body
Inventor: OTA KATSUICHI
IPC: G03G5/05
Filed: 1987-03-09
Abstract: PURPOSE:To enhance sensitivity and to lessen the degradation in electric chargeability arising from pre-exposing fatigue by incorporating polyethylene glycol monoether into a layer in which an electric charge generating material is dispersed. CONSTITUTION:An electric charge generating layer 1 and charge transfer layer 2 are successively laminated on a conductive base 3. The polyethylene glycol monoether is incorporated into the layer 1 in which the charge generating layer is dispersed. Namely, the polyethylene glycol monoether is chemically adsorbed in the charge generating material and provides the recombination center of the charges generated by light absorption and, therefore, the charges generated by the pre-exposing fatigue are quickly recombined and are thereby annihilated, conceivably by which the drop of the charge potential of the photosensitive body is suppressed. The electrophotographic sensitive body which has the high sensitivity, extremely lessens the degradation in the electric chargeability arising from the pre-exposing fatigue and obviates the drop of the charge potential even after repetition of the electrical charging and exposure is thereby obtd.
