Patent JP-S6017293-A (JP)
Title: Submersible pump
Inventor: TANAKA TEIJI
IPC: F04D15/00
Filed: 1984-06-27
Abstract: PURPOSE:To reduce the variation of the axial thrust due to the suction pressure by varying the differential pressure in a pressure balance pipe for connecting a pump discharge pipe with a casing wall opposed in the vicinity of the back-surface boss part of a vane wheel, in correspondence with the variation of the suction pressure of a pump. CONSTITUTION:A pressure balance pipe 16 connected to a pump discharge pipe is installed onto a casing wall 7 opposed in the vicinity of the back-surface boss part of a vane wheel 1. Therefore, the static pressure acting onto the side wall of the vane wheel 1 is represented by the figure, and though the leak flow passing through the balance pipe 16 flows to the outlet side of the vane wheel 1 from the pump discharge pipe, the differential pressure between before and behind a weiring ring 13 (namely the leak flow) can be set small by setting the area of the narrow slit part of the weiring ring 13 larger than the sectional area of the balance pipe 16. Therefore, the axial thrust which is generated towards the front-surface side wall 1a from the back-surface side wall 1b side by the revolution of the vane wheel 1 can be set to an arbitrary small value.

Title: Manufacture of semiconductor laser
Inventor: KOMAZAKI IWAO
IPC: H01L21/205
Filed: 1988-05-27
Abstract: PURPOSE:To provide a window region causing no reflection loss at combined parts by cleaving a part of crystals made to grow by selective illumination in the vapor growth of an organic metal for forming the end face for emitting laser light. CONSTITUTION:On a n-type GaAs substrate 1, there are deposited an n-type Al0.55Ga0.45As first clad layer 2 and an n-type Al0.4Ga0.6As optical guide layer 3 sequentially in that order without illumination of light. Then, while excimer laser beams are applied to the n-type GaAs substrate 1 selectively through a mask, an active layer of Al0.15Ga0.85As 4, a p-type Al55Ga0.45As clad layer 5 and a p<+>-type GaAs cap layer 6 are deposited sequentially in that order. The illuminated regions serve as windows to light generated by recombination of carriers, and the illuminated regions and the non-illuminated regions are combined taperingly as the level of breaking the resonator end face is increased. Thus, the wafer as a whole is subjected to growth without illumination until growth of the optical guide layer disposed under the active layer. Therefore, no step is produced at the combined parts. In this manner, it is possible to obtain a window region causing no reflection loss at the combined parts.
