Patent JP-H09145228-A (JP)
Title: Refrigerator
Inventor: NAKAMURA HIROKAZU
IPC: F25D19/00
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To prevent corrugated fins from disengaging from a pipe, by making a pipe outer size of bent portions, which are positioned at both ends of the corrugated fins and toward the corrugated fins, larger than a width dimension of notched grooves. SOLUTION: Corrugated fins 9b are moved toward one of bent portions of a pipe 9a between linear portions of the pipe when caulking dimensions are made loose between notched grooves 9c and the pipe 9a. When the corrugated fins 9b are moved, wind changes in direction, so that a set performance cannot be ensured and there is caused a bad effect such as the notched grooves 9c engaging the bent portions of the pipe 9a to rise up. To prevent this, stopper portions 14 are provided on the pipe 9a. The stopper portions 14 are formed by deforming the pipe 9a in a direction of crushing so as to become larger than a width dimension of the notched grooves 9c. Thus the fins 9b are restrained from movement. Accordingly, it is possible to readily perform a work of prevention of movement without the use of any special parts.

Title: Method and device for gas phase deposition
Inventor: DEIRU ROBAATO PAWAAZU
IPC: C03B37/014
Filed: 1990-11-13
Abstract: A method for making preforms by vapour phase soot deposition processes is disclosed, whereby an oxidizing atmosphere is used during at least part of the deposition process; e.g. during the deposition of the centre portion of the preform. The oxidizing atmosphere results from supplying oxygen, available to react with the fuel, in an amount which is stoichiometrically in excess of that required to fully oxidize the fuel. This results in enhanced dopant capture, reduced axial inhomogeneities (e.g. of dopant) in the consolidated preform and finished fibre, and an overall stabilization of the deposition process. A method for selecting burner flow rates which optimize the deposition process is also disclosed. The reaction deposition burner used to carry out the process has:- a first passageway (13) and second passageway (15), both of which carry at least oxygen but no fuel; a third passageway (17) to carry at least fuel and oxygen; and optionally a fourth passageway (19) to carry at least oxygen but no fuel, for shaping the flame.

Title: Molecular beam epitaxial growth method
Inventor: SAWATO HIRONOBU
IPC: H01S5/00
Filed: 1991-10-29
Abstract: PURPOSE:To provide a method for molecular beam epitaxial growth to form a lead sulfide p-n junction which is suitably applicable to form a current block layer formed through p-n junction. CONSTITUTION:A substrate 1 is fixed on a substrate holder 2, and a p-type lead sulfide semiconductor film is formed thereon in a molecular beam apparatus using dopant such as thallium. After the substrate holder is cleaned, an n-type lead sulfide semiconductor epitaxial film 6 is continuously formed thereon with no dopant added.
