Title: Deleterious radioactive ray shielding material
Inventor: ENOMOTO MASAKI
IPC: G21F3/00
Filed: 1994-12-27
Abstract: PURPOSE: To shield deleterious radioactive rays with an air-permeable fabric material having no adverse effect to a human body by molding a thermoplastic resin containing tungsten of a specific grain size at a specific wt.% into a fiber shape, and forming the fibers into a texture shape. CONSTITUTION: A thermoplastic resin containing tungsten of 99wt.% or below, preferably 30-99wt.%, is molded into a fiber shape, and the fibers are formed into a texture shape. The shape of tungsten is powder of the grain size 20μm or below, preferably 5-20μm. At the grain size of 0.5μm or below, for example, the workability when tungsten is formed into pellets is inferior, however the feature of the yarn is improved. When the grain size exceeds 20μm, the yarn surface is roughened at the time of spinning, and the succeeding process is hindered. There is no limitation for the thermoplastic resin in particular, a polyamide resin, a vinyl resin including vinyl chloride, or an acrylic resin can be used, however the polyamide resin is preferable in view of the affinity with tungsten.  A stabilizer such as a ultraviolet ray stabilizer or an oxidation inhibitor may be added as required.

Title: Finder and photographing optical system
Inventor: YAMAGUCHI TAKAO
IPC: G03B13/14
Filed: 1990-11-27
Abstract: PURPOSE:To eliminate parallax at the observing time of an object by observing the object by extracting a finder luminous flux from a photographing optical system at the observing time of the object on a long focal distance side. CONSTITUTION:Variable power is executed by a photographing system A by mutually changing an interval between a first lens group 1, and a second lens group 2. Besides, the photographing system A has a property that back focus on the short focal distance side thereof is short and the back focus on the long focal distance side is long on the contrary. That means, by arranging a reflecting member 3 such as a plane mirror at the part of the back focus side at the observing time of a finder in the case that the photographing of the long focal distance is executed, a photographing luminous flux from the photographing system A can be guided to the real image surface 9 of a finder system. Thus, the parallax whose tendency becomes remarkable on the long focal distance side of a compact camera where in variable power can be executed is reduced or eliminated.
