IPC: G02C5/00
Filed: 1989-12-07
Abstract: PURPOSE:To obtain the brazing material for a shape memory alloy having higher and stabler joint strength by forming the brazing material of gold, silver and copper. CONSTITUTION:The brazing material for the shape memory alloy is constituted of the gold, silver and copper. Namely, the generation of compds. and deposition thereof at the grain boundaries, etc. and the creation of a segregation state are preferably averted at the time of the diffusion of the two members or the constituting elements from the inside of the brazing material to each other at the joint boundary. The gold is, thereupon, preferable as the gold has good wettability and hardly forms the reaction product with other metals. The silver is selected as the silver has the compatibility with the gold and lowers the m. p. Further, the copper is selected in order to lower the m. p. The intermetallic compd., the reaction product, segregation, etc., are substantially eliminated at the joint boundary in this way and the brazing material wets well with the two joining members. The tensile shearing strength fluctuates less and the stable and high strength is obtd.

IPC: H01S5/00
Filed: 1993-12-16
Abstract: PURPOSE:To miniaturize the whole constitution of a light source, and stabilize the oscillation wavelength, by integrally retaining a semiconductor laser element, an optical isolator, and a collimator lens, with a housing satisfying a specific conditional expression. CONSTITUTION:An optical isolator 3 is arranged just behind the beam output port of an LD element 2, and a collimator lens 4 is arranged on the output port side of an optical isolator 3. By integrally retaining the above components with a housing 5, and a light source unit 1 is formed. The housing is composed of material of small thermal conductivity whose value (k) [Wm<-1>.K<-1>] satisfies a relation 0<k<2. Since the oscillation wavelength of the LD element changes according to the temperature or the injection current, the temperature and the current must be controlled when the element is used as the light source of a length measuring machine. The material of small thermal conductivity whose value is in the range of the above conditional expression is applied to the housing, and the temperature is controlled to be equal to a previously set value by driving a temperature actuator. Thereby the oscillation wavelength can be stabilized.
