Patent JP-S63282494-A (JP)
Title: Heat exchanger
Inventor: MATSUURA OSAMU
IPC: F22G3/00
Filed: 1987-05-13
Abstract: PURPOSE:To dissolve a problem on fatigue crack occasioned by a fluctuation in a condensate temperature at a part where a sleeve is mounted to the pipe end connection part of the outlet of a heat transfer pipe, by a method wherein, in a heat exchanger being of a system wherein heated steam is condensed in a heat transfer pipe, a sleeve is mounted to the pipe end connection part of the outlet of a heat transfer pipe. CONSTITUTION:In an outlet part 19 of a heat transfer pipe 6, a heat transfer pipe 6 is secured and supported to a tube plate 7 by welding at 20, and is mounted in a state to cover the weld part 20 with a sleeve 22. The sleeve 22 is secured to a heat transfer pipe 6 on the steam upper stream side 23 and is secured at an outlet part 24 to the tube plate 7, and a space 25 is formed between the weld part 20 at a pipe end and the sleeve 22. Therefore, overcooled condensate 15 flows over the sleeve 22, and the temperature change of condensate 15 is hardly propagated to the weld part 20 due to the effect of the space 25. This constitution prevents production of a repeat thermal stress, by which the occurrence of crack is caused, at the weld port 20, and enables provision of a heater having high reliability.

Inventor: YUUJIEN AASAA FUITSUTSUJIERARU
IPC: H01L21/203
Filed: 1994-05-27
Abstract: PURPOSE: To manufacture a high equality semiconductor hetero-structure of gallium arsenide of germanium by exposing a germanium surface to an environment in which substantially no arsenic is present, depositing a gallium layer on the surface, then growing a gallium arsenide layer. CONSTITUTION: A substrate 10 is introduced into a growth chamber where no arsenic is present, and exposure is made by attaching/detaching an oxide on a Ge surface 11. Then, the germanium surface 11 is covered with a preliminary layer of gallium. After the gallium preliminary layer is grown, a GaAs 12 is grown. The advantage of his method is that it promotes two-dimensional growth of a single region of gallium arsenide. Therefor, an anti-phase border is removed, and threading dislocation, freely slides in GaAs to generate a long misfit dislocation at a GaAs/Ge interface. As a result, a high quality GaAs/Ge hetero-structure with which optoelectronic devices are manufactured is obtained.

Title: Reflection type liquid crystal display device
Inventor: OKAMOTO MASAYUKI
IPC: G02B5/30
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To obtain high visibility by setting up the integration value of a refractive index in the thickness direction of a liquid crystal(LC) layer about light advancing in the normal direction of a substrate to a specific value and arranging an optical phase difference compensating plate between the LC layer and a polarizing plate. SOLUTION: Illumination light such as external light is made incident upon the LC layer 1 through the polarizing plate 10 and the incident light is observed from the side of the plate 10. Only a linearly polarized light component of a specific azimuth out of the illumination light is selectively transmitted by the plate 10 and its polarization state is changed by the optical phase difference compensating plate 8. As a condition for attaining fine display, the LC layer 1 is required to have proper double refraction for light passed in the normal direction of the display surface of the LC layer 1 even when the LC layer is in any orientation arrangement, i.e., bright display or dark display.  A component having 100 to 180 nm double refraction and capable of controlling two orientation states can be adopted as an LC layer candidate and shevron layer structure e.g. obtained in the case of forming the smectic C phase of an LC component like a layer can be utilized.
