Title: Character separating device
Inventor: OUCHI SATOSHI
IPC: G06K9/20
Filed: 1989-04-17
Abstract: PURPOSE:To separate a character area on a dot with high accuracy by extracting an edge picture element from a smoothed picture and deciding it as a character area where the value of the count of an extracted edge picture element exceeds a prescribed value. CONSTITUTION:A smoothing processing section 1 applies smoothing filter to a digital multi-grade input picture (characters and dots are in existence in mixture such as a document picture or the like). A binarizing processing section 3 binarizes a differentiating processing picture by a differentiating processing section 2 at a specific level th1. A picture element made effective by the binarizing processing, that is, a picture element with a level over the level th1 or over is an edge picture element. A count processing section 4 counts the extracted edge picture element and decides the character area and the dot area depending on the count value P. Thus, not only characters on a white background but also characters on dots are separated with high accuracy.

Title: Neutron detector
Inventor: KAKINUMA HIROMI
IPC: G01T3/00
Filed: 1983-05-31
Abstract: PURPOSE:To maintain the ability to convert prompt neutron to thermal neutron even in a high temp. state such as an accident in a nuclear reactor by replacing PE with crosslinked PE having a higher m.p. CONSTITUTION:A neutron detector body 2 is housed in an outside box 1 and crosslinked PE 31 is provided between the box 1 and the body 2. Hydrogen atoms of roughly the same number per unit area as that of conventional PE are contained in the PE housed in the box 1 and therefore the ability to decelerate prompt neutron to thermal neutral does not change and the neutron sensitivity does not change accordingly. Since the m.p. is high, the PE is hardly deformable even if the temp. thereof rises and the detector is usable at a high temp. as well.
