Title: Production of ktp crystal by atmospheric control growth
Inventor: SASAKI TAKATOMO
IPC: C01B25/08
Filed: 1994-07-18
Abstract: PURPOSE:To obtain a KTP crystal improved in transmittance, suppressed in light absorption in the visible region, and excellent in practical performance, by growing a potassium titanylphosphate (KTP) crystal in an inert gas atmosphere. CONSTITUTION:This crystal is obtained by growing a KTP crystal in an inert gas atmosphere. In general, a KTP crystal colors during its growth in the presence of oxygen, decreasing its transmittance. Its cause is supposed to be due to the contamination of the growing crystal with impurities such as Pt<3+>. The above coloration and impurity contamination cannot be avoided by potassium oxide addition or annealing in an oxygen gas atmosphere as conventionally practiced. By this method, the optical absorption (400-520nm: visible region) of this crystal can be reduced, and use of this crystal enables highly efficient wavelength conversion.

Abstract: PURPOSE:To provide a double row fork device which can align fork reach of a group of forks automatically and a taking in and out device with double row fork device which can reserve cargoes on shelves without disturbing an attitude of the cargoes. CONSTITUTION:When each primary fork 27 of each fork device 18, 19 advances and retracts, fork reach tends to differ between the fork devices 18 and 19 due to the elongation of a chain for interlocked advance and retraction. However, it is possible to align and move each primary fork 27 integrally owing to the provision of an interlocking tool 60 between the primary forks 27. Consequently, each primary fork 27 advances and retracts in a condition in which a difference in fork reach is small relatively. A cargo 5 to be scooped between primary forks 27 is not distorted at the center of a fork and a shape of the cargo is not disturbed.

Filed: 1986-07-15
Abstract: PURPOSE:To form grooves vertically even though widths of the grooves are narrow and perform an etching treatment of silicon substrate, depths of which vary slightly by using mixed gas consisting of SiCl4, Cl2, and fluorine series gas that is lacking in C. CONSTITUTION:With the introduction of mixed gas consisting of SiCl4, Ol2, and fluorine series gas that is lacking in C in a vacuum vessel 1, Glow discharge permits a plasma to be developed and a silicon substrate 4 is etched in this plasma. being lacking in C, fluorine series gas, that is NF3 for instance, produces a large quantity of F radicals in the plasma and these F radicals have a strong property to etch Si in accordance with an isotropic manner. Then, a well balanced state between a deposition reaction attained by adding NF3 at wall parts of groove sides and a transverse etching reaction obtained by F radicals allows the silicon substrate to form vertical grooves with uniform depths. Thus, even narrow grooves can be vertically formed to achieve an etching treatment of the silicon substrate 4, depths of which vary slightly.

Abstract: PROBLEM TO BE SOLVED: To efficiently produce oxygen of a low-purity by cooling an inflated low-pressure stock air and a low-temperature compressed high-pressure stock air by heat exchange with a liquefied hydrogen for supplying fluid and cold heat which are obtained from a low-temperature distillation. SOLUTION: By setting a warm edge temperature difference between a feed air with a high pressure and a low-temperature nitrogen gas discharged from a single distillation tower 7 to at least 5 deg.C in a main heat exchanger 5, a nitrogen gas can have a stock air pre-cooling capacity, thus pre-cooling a compression stock air without using any power of a freezer and the like, thus simplifying a device configuration and at the same time drastically reducing the unit of a product low-purity oxygen gas. On the other hand, one portion of a liquefied oxygen separated to the bottom part of an edge distillation tower 7 is introduced to a reboiler 11, is heated, and becomes a rising gas. After the remaining liquefied oxygen is compressed by a liquefied oxygen pump 13, it is heated and is evaporated.  The oxygen gas exchanges heat with a feed air by the main heat exchanger 5 and is collected as a product low-purity oxygen gas.
