Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To fix the position of a door at a slightly open state by fixedly clamping a horseshoe-shaped clip body made of elastomer between side edges or upper edges of a door. SOLUTION: A door stopper comprises a horse shoe-shaped clip body made of elastomer whose opening edges 1a and 1b are provided with a smaller width B. Projected strips 3a and 3b are formed on an inner surface of this opening end. The width B1 between both projected strips is formed substantially 1/2 of the width B2 between the inner surfaces on the base of the clip body 2. The clip body 2 is properly deformable and provided with elastic properties to return to the original shape. The width B1 is arranged to be smaller than the thickness T of a door 4 while the width B2 is formed so that it may be larger than this thickness T. The clip body 2 is locked with the side edge 4a of the door 4, thereby interposing the clip body 2 between the door 4 and a door frame 5 and forming a clearance. This construction makes it possible to halt the door 4 at that position for ventilation or the like.

Filed: 1982-12-15
Abstract: PURPOSE:To provide a paint which exhibits good resistance to cement lye by a single application to cement building material, containing a hydrolyzable organo- silane. CONSTITUTION:A building paint contains a hydrolyzable organosilane compd. conrg. hydrolyzable sustituents and stable hydrophobic groups in a ratio of 1:3- 3:1 in the molecule, such as trimethoxymethylsilane, ethoxytriethylsilane, etc. Most of the hydrolyzable organosilane contained in the paint penetrates into the interior of building materials and is chemically bonded to silanol in building substrate to form a waterproof layer. A film-forming component in the paint is spread over the surface layer to form a coating film layer so that a double- layer structure is formed by coating. Hence, it is presumed that the migration to the surface of the coating film and an adverse effect on the coating film are inhibited by the waterproof layer formed by the hydrolyzable organosilane.

Filed: 1989-08-24
Abstract: PURPOSE: To improve light efficiency and luminance by arranging a cathode and an anode on an upper surface of a back face plate, interposing a matrix- shaped striped insulating layer in a bottom part of the cathode together with the anode, and respectively forming a partition wall and a barrier lower than this on both side edges of the insulating layer. CONSTITUTION: A cathode Kb and an anode Ab are arranged on a back face plate Bb, and a matrix-shaped striped insulating layer Ib is interposed in a bottom part of the cathode Kb together with the anode Ab, and a partition wall Pb and a partition wall Pc lower than this are respectively formed on both side edges of the insulating layer Ib or the like. In this case, a discharge passage is bent and formed in a bridge shape to bypass the barrier Pc. That is, discharge between the cathode Kb and the anode Ab is generated through an inverse U-shaped passage performed through a straight line passage by the barrier Pc, but since a length of a positive column contributing to excitation of a phosphor layer Eb becomes long, the phosphor layer Eb can be strongly excited with sufficient discharge efficiency. Therefore, a high luminance image can be obtained with high discharge efficiency.
