Title: Hot-wall epitaxial growth apparatus
Inventor: SHINOHARA KOJI
IPC: C30B23/02
Filed: 1987-04-10
Abstract: PURPOSE:To obtain the titled growth apparatus capable of forming an epitaxial layer having large area and uniform thickness on a substrate held above a crucible containing a source for forming epitaxial crystal layer, by forming the opening part of the crucible in elliptic shape and the side part of the crucible in flat shape. CONSTITUTION:The cross-section of the top opening part 32 of a crucible 31 has flat elliptic shape and the bottom of the crucible 31 is furnished with a bottom-closed inner tube 33 protruded downward. A source material (PbTe or PbSnTe) for epitaxial layer to be formed on a substrate 35 (e.g. PbTe) is placed in the crucible 31 and the inner tube 33 contains Te for the control of the composition of the epitaxial layer. Accordingly, the molecules evaporated from the bottom of the crucible 31 are moved along the dotted lines and reach the positions A, B and C at the opening part 32. Since the opening part 32 has flat shape and the dimension l in the direction of the short side is short, all parts of the opening part 32 have equal distance from the hot wall 34 of the crucible 31. Consequently, the ratio of molecules slantly incident upon the substrate 35 after collision to the hot wall 34 is decreased to equalize the amount of evaporated molecules of the source material.

Title: Method for measuring liquid surface level in cz method
Inventor: KIZAKI SHINGO
IPC: C30B15/20
Filed: 1991-03-27
Abstract: PURPOSE:To accurately measure the liquid surface level of a melt in a crucible in producing a single crystal using the Czochralski (CZ) method. CONSTITUTION:Light emitted from the liquid surface of a melt 4 in a crucible 2 is concentrated with a lens 11 and the concentrated light is irregularly reflected with a reflecting plate 12.

Title: Resin molding machine
Inventor: SATO SUMIO
IPC: B29C45/40
Filed: 1995-04-14
Abstract: PURPOSE: To reduce the cost by using moving means without controlling the moving amount of a bar by switching the moving force of the bar of the means to the state of transmitting to the moving element or the state of transmitting to an ejector pin. CONSTITUTION: A columnar barlike moving element 34 is solely movably engaged within molten resin passages 16b, 18. The moving force of a hydraulic ejector (bar) 15a is switched by switching means 106 to the state of transmitting to the element 34 or the state of transmitting an ejector member 23. Thus, the movement of the ejector 15a in the case of moving the element 34 to the return position and the movement of the ejector 15a in the case of moving the member 23 to a cavity 17 side are independently conducted. Accordingly, since it is not necessary to control the moving amount of the ejector 15a at two stages, the cost can be reduced.
