Title: Detection of internal defect of crystal
Inventor: FURUKAWA JUN
IPC: G01N21/88
Filed: 1994-02-28
Abstract: PURPOSE:To certainly detect the internal defect of the surface layer of a crystal without being almost affected by the surface state of the crystal by enabling infrared rays to be made incident on the crystal in the vicinity of the surface thereof with a high efficiency by utilizing such a phenomenon that the infrared rays made incident on the surface of a substance at a low angle are totally reflected from the surface of a substance. CONSTITUTION:Infrared rays IR are made incident on the rear surface 12A of a wafer 12 at a predetermined incident angle. Infrared rays IR are guided to the vicinity of the surface of the wafer so that the infrared rays transmitted through the wafer 12 are totally reflected from the surface 12B of the wafer 12. When the internal defect (d) of the wafer 12 is irradiated with infrared rays IR, light scattering is generated. 90 deg. scattered light is condensed to be formed into an image on a sensor 14 to detect the internal defect of the wafer.

Title: Optical element module
Inventor: CHINEN YUKIO
IPC: G02B6/42
Filed: 1989-03-07
Abstract: PURPOSE:To prevent an optical coupling between the tip of a fiber element and a light emitting element from dislocating in position owing to thermal variation by fixing the periphery of the tip of the fiber at the inside of one end of a ferrule and fixing the clad at the other end part, and forming an air hole penetrating the intermediate part. CONSTITUTION:The tip of the fiber element 23a is inserted into a ceramic sleeve 32 which is pressed in the lower end of the ferrule 31 and fixed with epoxy resin 33. Further, the jacket 23b of an optical fiber 23 is fixed at the upper end part of the ferrule 31 with epoxy resin 34. Namely, the tip periphery of the fiber element 23a is fixed at the inside of one end of the ferrule 31 and a jacket 23b is fixed at the other end part. Then, no epoxy resin is filled in the intermediate part of the ferrule 31 except both end parts and the air hole 35 which penetrates the ferrule 31 is formed in the intermediate part. Consequently, even if the ambient temperature varies, almost none of the influence of heat expansion is exerted and the end part position of the fiber element 23a never shifts.

Abstract: PROBLEM TO BE SOLVED: To prevent liquid compression from occurring by suction of liquid refrigerant by discharging stagnating refrigerant from a discharge port provided about the bottom of a compressor by using a refrigerating machine oil, and evaporating the liquid refrigerant in a evaporation pipe to flaw it out into a suction pipe. SOLUTION: During interruption of a compressor 10 refrigerating machine oil 7 and a liquid refrigerant, both being mutually not soluble, are separated into two layers where the refrigerating machine oil 7 stagnates in a shell 11 as an upper layer with the liquid refrigerant as a lower layer owing to their specific gravities. In this state, when the operation of the compressor 10 is started and simultaneously a two-way valve 14 is opened, the liquid refrigerant is sucked through a discharge hole 12 communicated with a suction pipe 10a, and is sucked into the compressor 10 through a discharge pipe 13, the two way valve 14, a flow rate limit valve 15, an evaporation pipe 16, and the suction pipe 10a.  At this time, the liquid refrigerant is limited in its flow rate by the flow rate limit pipe 15 after passage through the two way valve 14 and is reduced in its pressure, and is further evaporated in the evaporation pipe 16 whereby when it reaches the suction pipe 10a, it becomes refrigerant vapor so that liquid is prevented from being compressed in the compressor 10.
