Title: Manufacture of natural wood laminated sheet-like object
Inventor: KOBARI TOSHINORI
IPC: B32B37/10
Filed: 1995-03-29
Abstract: PURPOSE: To obtain flexibility in either vertical or horizontal direction and improve durability by arranging a parquet pattern such as a checkered pattern using a natural wood laminated sliced sheet and lining the sheet with three layers of base sheet. CONSTITUTION: A band-like base material consists of a band-like thinly sliced sheet of paulownia square timber which is lined with two layers of base sheet 2, 8. In addition, the base material is composed of a series of continuous square wood sliced sheet pieces 1a measuring d am high and wide which form a band horizontally, and are arranged in such a manner that the vein directions of the adjacent square wood sliced sheet pieces 1a... are orthogonal with each other. Next, the adjacent band-like base materials are arranged flatly, on a rectangular base sheet 12 with a thermofusible adhesive 3 applied to the surface, in the longitudinal direction of the vertically set band-like base material, in such a manner that each one of the sliced sheet piece 1a is staggered vertically and closely to each other so as to allow the veins of the sliced sheet pieces 1a to be orthogonal with each other. Finally, this laminated sheet-like material is hot-pressed and then is cut along both edges to obtain a checkered pattern laminated sheet-like object 13 of paulownia.

Title: Semiconductor device
Inventor: TSUKADA HIROMI
IPC: H01L23/10
Filed: 1984-05-16
Abstract: PURPOSE:To carry out good sealing of the outer appearance with high reliability by a method wherein two kinds of material having different melting points are used as the sealant. CONSTITUTION:A high melting point (highly viscous) glass 2 is applied inside the peripheral edge of the back of a cap 1, and a low melting point (lowly viscous) glass 3 is applied outside. Next, the base is fused to the cap 1 through a belt furnace for sealing or the like. When the viscosity of the glass is low, the wet spreading of the glass is good, that is, the outer appearance is good; however, blow holes, etc. generate. When the viscosity is high, blow holes, etc. less generate; however, the outer appearance of the glass becomes worse. Therefore, the outside viscosity should be made lower and the inside one higher at the time of sealing.
