Title: Integrated heat exchanger
Inventor: KOBAYASHI HIDETAKA
IPC: F28F9/26
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To prevent cracking a tank by connecting a first upper tank and a second upper tank, or a first lower tank and a second lower tank to each other by means of a connecting member, and forming a projection part projected upward or downward between connecting parts. SOLUTION: A first upper tank 25 and a second upper tank are connected to each other by means of a connecting member 45, and a projection part 47b projected upward is formed between connecting parts 45a, 45b of the connecting member 45. Impact force applied on the projection part 47b of the connecting member 45 is dispersed into the first upper tank 25 and the second upper tank 29 through the connecting member 45. It is thus possible to prevent cracking and the like from generating on the upper tanks 25, 29, and it is also possible to avoid leaking fluid in the upper tanks 25, 29 outward. In the case where the impact force is large, the connecting member 45 is peeled from the connection part 45b arranged on the second upper tank 29 side whose brazed area is small.

Title: Selective growing method
Inventor: TANAKA SHIGEHISA
IPC: H01L29/06
Filed: 1993-12-08
Abstract: PURPOSE:To accurately perform selective growing in a fine area by growing crystal by using a mask formed by selectively removing a part of a semiconductor multilayer structure formed of a plurality of semiconductor thin films of different types. CONSTITUTION:A part of a multilayer structure GaAs layer 2 formed by growing a GaAs layer 2 and an AlGaAs layer 1 on a substrate 4 is selectively removed and a comb-shaped extremely fine mask is formed. The Ga and As molecular beams 6 are applied on the GaAs substrate 7 from an Ga and As molecular beam source 5 using the mask, and molecular beam epitaxial growing is performed. Since only the molecular beams that pass through the opening reach the substrate, fine wires 8 that have extremely fine width are selectively crystal-grown in an extremely fine area depending on the shape of the opening. Then, a molecular beam is emitted from a source arranged in a direction different from the molecular beam 5 so as to bury the fine wire structure to form a quantum wire structure.
