Title: Method for vapor epitaxial growth
Inventor: TOSHIDA YOSHIKAZU
IPC: C30B25/02
Filed: 1989-09-26
Abstract: PURPOSE:To deposit an Si single crystal film without any defects at a high deposition rate and a low temperature by specifying the linear velocity of diluted disilane in growing the Si single crystal film on an Si single crystal substrate using the disilane as a raw material. CONSTITUTION:Diluted disilane is used to epitaxially grow an Si single crystal film on an Si single crystal substrate. In the process, the linear velocity of the diluted disilane is kept at 5-100cm/min. The concentration of the disilane in a raw material gas is preferably 0.001-1vol.%. more preferably 0.002-0.5vol.%. An inert gas, such as H2, He or Ar, can be used as the diluting gas in the raw material gas; however, the inexpensive H2 is preferred. If the linear velocity of the raw material gas is lower than 5cm/min, the amount sufficient for crystal growth cannot be fed. If the linear velocity exceeds 100cm/min, deposition defects are caused in the resultant crystal film.

IPC: H01L23/36
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To hold all heat generative members at a specified temp. by cooling heat generating members having high heat-generating densities by a jet flow structure which utilizes a gas flow mixed with a gas flow approximately along a substrate and crosses it with a flow along the fin surface of a heat sink. SOLUTION: A multiple-chip module 30 has a high heat-generating density and hence needs a jet flow cooling structure to cool the individual members. It jets air 4 from both side fins, approximately perpendicularly to a gas flowing direction, while a cooling air 1 blown approximately parallel to a substrate is accelerated in a restricted passage at the module 30 being cooled with the jet flow. At a heat sink the air flow cooled with the jet flow is jetted, approximately perpendicularly to the gas flow approximately in parallel with the substrate, and hence both air flows are mixed to send the cooled air enough to small electronic elements 40 round the module so that electronic elements 45, 46 mounted on the heat sink 20 are well cooled with the low temp. air.

Title: Sheet for transparent part of paper box
Inventor: HASHIMOTO TADASHI
IPC: B65D5/52
Filed: 1990-09-20
Abstract: PURPOSE:To prevent breaking of paper material and wrinkling of a transparent part when a paper box original paper consisting of a transparent sheet and the paper material pasted to each other and formed in a developed shape by a method wherein a thin belt having a specified layer thickness is formed at a part to be bent of the transparent sheet, and the width of the thin belt is prescribed times as thick as the thickness of the other part of the sheet. CONSTITUTION:A thin belt 2 is formed along a part to be bent of a transparent sheet 1, and it is designed that the thickness (t) of the thin belt 2 is 50% or less than the thickness (T) of the other art of the sheet 1 and the width (w) is three to twenty times as large as the thickness (T). As only the part to be bent is thin, when the sheet 1 is bent, an extension volume of a paper material 3 is so small that the paper material 3 is unlikely to break at corner parts. In addition, the other part is thick enough for preventing wrinkling all over a transparent part. If the thickness (t) is larger than 50% of the thickness (T), when the sheet 1 is bent, the paper material 3 is pulled and extended at the corners, and thus it is likely to break. On the other hand, if the width (w) is smaller than three times the thickness (T), the sheet 1 is likely to break for the same reason, while if it is larger than twenty times, the sheet is likely to wrinkle.
