Title: Vapor growth method for compound semiconductor single crystal
Inventor: YAMAGAMI TOMOJI
IPC: C30B23/00
Filed: 1986-05-30
Abstract: PURPOSE:To grow a homogeneous and high-quality compd. single crystal of optional size by vaporizing the raw material by a sublimation process or a halogen transport process, introducing the vapor into a seed crystal chamber to extend a seed crystal, and growing a bulk single crystal on the tip of the seed crystal in a single crystal growth chamber. CONSTITUTION:A crystal growth vessel 1 is separated by a partition wall 4 into the seed crystal chamber 2 and a raw material chamber 3. A II-VI compd. raw material 5 such as ZnS and ZnSe is charged in the raw material chamber 3, and a seed crystal 7 mounted in a heat sink 6 is arranged in the seed crystal chamber 2. The crystal vessel 1 is inserted into a heated furnace having a requisite temp. distribution. The vapor of the raw material 5 generated in the furnace flows into the seed crystal chamber 2 through the bored hole of the partition wall 4, and is deposited on the seed crystal 7 to grow a crystallite 8. The highly crystalline tip of the crystallite 8 convergently grown to the vicinity of the bored hole of the partition wall 4 forms a good-quality seed crystal, and a uniform and high-quality bulk single crystal 9 of the compd. semiconductor is grown at the upper part of the raw material chamber 3.

Title: Detection system for overspeed of hydraulic turbine
Inventor: HAYAKAWA NORIO
IPC: H02P9/04
Filed: 1981-08-14
Abstract: PURPOSE:To protect a hydraulic turbine by operating a protecting device when a speed of the hydraulic turbine exceeds a determined value for not less than a specified time period and by detecting a unconstrained speed driving state without any operation of the protecting device caused by a transient overspeed. CONSTITUTION:In cases where a speed caused by cutting out a load exceeds an operating value V4 and an overspeed detection relay 1 operates, a set time T5 of an integration type timer is determined to an appropriate value exceeding T0 (an operation time of an overspeed detection relay during a no load operation). In cases where the following equation: TS<=T1+T2+... wherein T1 indicates an operation time of an overspeed detection relay during a unconstrained driving is satisfied, when TS exceeds T1, not to mention when TS is below T1, the speed is judged to be at a level not occuring during a normal drive. As the result, a hydraulic turbine 6 can be protected by operating a protecting device 5 according to the directions of a protecting device 2 to close an inlet valve.

Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To provide a carrier for optical communication which can be automatically mounted on a substrate by a carrier mounting device for optical communication with high position accuracy so as to secure the required photocoupling level. SOLUTION: Concerning an optical element carrier 2, an alignment mark 21 is formed on a plate-shaped object (substrate). A mask is formed in an area excepting for the area to become the alignment mark 21 on the surface of that plate-shaped object, wet etching is applied and a hole throughout the rear side is formed. The alignment mark 21 is an opening on the front side of that hole. Since the alignment mark 21 and a first rear side alignment mark are formed through one etching process, these marks can be highly accurately aligned each other. The accuracy in the alignment of an alignment mark 22 and a second rear side alignment mark is made similar as well.  By loading the optical element carrier 2 through the mounting device onto a substrate 1 while aligning the first and second rear side alignment marks with alignment marks 13 and 14, an optical element 25 can be automatically mounted on the substrate 1 with high position accuracy.
