IPC: B44C5/00
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To easily modify an already existing curved face concrete structure to a structure which is gentle to the natural environment and suitable for the raising of biosystem at a low cost and low labor by a method wherein on a flexible decorative base material, a surface decorative material such as natural stones is affixed with an adhesive, and a curved face structure decorative material is formed. SOLUTION: As a flexible base material 2 for this curved face structure decorative material 1, an aluminum sheet, sheet-like articles of tin plate, galvanized sheet steel, rubber, plastic, FRP and fabric are used, and on the top, a surface decorative material 3 comprising a natural stone such as lava, which is water-permeable, has numerous pores, and of which the surface has an uneven shape, is affixed with an adhesive.

Title: Envelope
Inventor: SHIGEMI KAZUTOMI
IPC: B42D15/08
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To prevent the upper envelope paper sheet positioned at the outer periphery of a printing part in a bent state from generating a warp and obtain accurate print, smooth feed and clear printed image, by making thinner the thickness of the upper envelope paper sheet provided with a write-in part than the thickness of the lower envelope paper sheet. SOLUTION: The upper envelope paper sheet 2 and the lower envelope paper sheet 3 are superposed and the three sides are bonded with an adhesive 4 to form an envelope. These envelopes are continuously connected at the boundaries of perforations for folding and cutting purposes to constitute continuous envelopes 10. When the upper envelope paper 2 is made of paper with basis weight of 55kg for instance, the lower envelope paper 3 is made of paper with basis weight of 70kg. And hence, when an envelope 1 is fed in a printer, even if the front face side of the upper envelope paper sheet 2 is positioned at the outer periphery of a bend and bent there, the upper envelope paper sheet is prevented from warping owing to mutual shifting and hence, the envelopes can be smoothly and accurately fed and printed.

Title: Cap for optical element
Inventor: INADA KATSUMI
IPC: H01S5/00
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To reduce thermal distortion and residual stress at the time of sealing to prevent the inclination of a window sheet glass and thereby increase the sealing strength and the airtight reliability by forming a ring-shaped projection which surrounds a light transmitting window hole in an inner face of a top plate section of the main body of a cap. SOLUTION: The main body 1 of a cap is formed of metal whose coefficient of thermal expansion is approximate to that of glass. The main body 1 is provided with an annular top plate section 1a having a round window hole 4 at the center and an annular flange section 1c extended nearly vertically from the periphery of the top plate section 1a. Inside the top plate section 1a, an annular projection 6 which surrounds the light transmitting window hole 4 is provided. By this structure, thermal distortion is reduced at the time of sealing. After the sealing of a window sheet glass 2, the projection 6 cuts and catches into glass solder 3 to reduce residual stress of the glass solder 3. An anchoring function of the projection 6 prevents the release of the glass solder 3.  As a result, the window sheet glass 2 can be sealed with good enough sealingness and thereby the airtight reliability of the cap for an optical element can be increased.
