Patent JP-S6065523-A (JP)
Title: Manufacture of semiconductor film
Inventor: KITAJIMA HIROSHI
IPC: H01L21/86
Filed: 1983-09-20
Abstract: PURPOSE:To enable the improvement of a semiconductor thin film even if the film is thick by a method wherein ion implantation is performed along a crystallographic axis of a low order to make amorphous only the disorderly region in the vicinity of a defect, after which recrystallization is done by annealing. CONSTITUTION:When ion is implanted in a substrate vertically, the part when a lattice defect 14 exists is made into an amorphous region 15 and the part except that is still a single crystal region 16. After that, heat annealing is done in a nitrogen atmosphere to cause recrystallization and the lattice defects in a recrystallization region 17 are reduced. The ion implantation is thus performed along the crystallographic axis of a low exponent when the defects exsisting in the thin film are reduced by ion implantation and annealing. Consequently, the vicinity of the defects can be selectively made to be amorphous and the damage upon a good crystalline region is less and also the range of thickness of a film which can be applied is enlarged by ion implantation along a low-order crystallographic axis.

Title: Hermetic compressor
Inventor: SUZUKI NOBORU
IPC: F04C28/28
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To attain size reduction by improving pressure resistant strength in the vicinity of a glass terminal, and improve reliability by applying it even to a refrigerant having high saturation pressure by forming the sealed vessel of a cylinder part whose one is sealed and an upper cover part where the glass terminal is arranged in the central vicinity. SOLUTION: In a sealed vessel 1, a cylindrical vessel 11 whose one is sealed is covered with an upper cover part 12, and a glass terminal 14 is installed in the upper cover part 12. The upper cover part 12 and the glass terminal 14 are installed over the whole circumference by welding, and are formed as a sealed structure. The glass terminal 14 is installed in the center of the upper cover part 12. When internal pressure of the sealed vessel 1 abnormally increases, the upper cover part 12 and the cylindrical vessel 11 swell in a spherical shape by pressure. Since the glass terminal 14 exists in a central part of the upper cover part 12, and force applied as a whole is uniformized, and stress does not concentrate, and pressure resistant strength of the sealed vessel 1 can be improved. Therefore, when a refrigerant having high saturation pressure is used, necessary pressure resistant strength of the sealed vessel 1 can be secured.

Title: Reversible thermal coloring composition and reversible recording medium employing it
Inventor: FURUYA HIROMI
IPC: B41M5/337
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To obtain a reversible recording medium applicable to wide working conditions and environmental conditions while sustaining stabilized coloring/discoloring properties by employing a phenolic compound shown by a formula as an electron acceptive compound. SOLUTION: The reversible thermal coloring composition is composed of a coloring agent, i.e., an electron donative color developing compound, and a developer, i.e., an electron acceptive compound, wherein a colored or discolored state can be formed relatively depending on the difference of the heating temperature and/or the cooling rate after heating. The electron donative acceptive compound employs a phenolic compound shown by a formula (where, X represents a bivalent group including a hetero atom, R1 , R2 represents a hydrocarbon group, and n represents 1-3). A coloring state obtained through quenching from a fused state is held in a state where the developer and the coloring agent are mixed and aggregated such that the molecules thereof can cause a contact reaction.  On the other hand, discoloring through gradual cooling from a fusing point state or through temperature rise tram a coloring state is caused by variation in the aggregation structure at the temperature and phase separation or crystallization of the developer.

CONSTITUTION:A transparent insulation film 20 used also for a protection layer is formed all over the surface except for an input/output terminal section 17, and a metal film 21 is formed all over the surface of the film. On the occasion, the part of the metal film above 2 photosensitive section 2 shaped in an array is formed as an open pattern so that light can be incident through it operating as a window 22 for entry of light. According to this construction, wiring and others provided for a process from the reception of light by the photosensitive section 2 to the impedance conversion by IC 14 for detection are all covered with the metal film 21. Therefore, a sufficient light-intercepting shield effect is exhibited, there is no possibility of genera tion of electricity by the light in any part other than the photosensitive section 2, and an effect of noise due to a high-frequency electric wave is excluded substantially. Thereby a ratio between a light current and a dark current, i.e. an S/N ratio, can be set to be large, and reading of an original picture and the like is made accurate.

Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To prevent the corrosion of boiler piping by a chloride and to prevent the resynthesis of dioxin by extracting the salts in dust captured from a phyrolysis gas contg. combustible dust splashing from a waste melting furnace with water, then dehydrating the salts and refeeding the dehydrated cake thereof into the waste melting furnace. SOLUTION: The dehydrated cake from which the salts are removed is fed again into the waste melting furnace 1 at its top and is converted to the pyrolysis gas in the waste melting furnace. The slag component is made into molten slag. The combustible gas from which the combustible dust to which the salts are stuck is removed by a dust remover 7 is sent to a combustion chamber 12 to be burned. the generated waste gas is sent to a waste heat boiler 13 where heat is recovered. The waste gas is cooled by a waste gas tamp. controller 14 and is released to the atmosphere after dust collection.  If operation is so carried out that the temp. of the pyrolysis gas discharged from the waste melting furnace top falls to <=400 deg.C, the salts in the pyrolysis gas can more migrate into the dust and, therefore, when the dust in the waste gas is collected by the dust collector, the salts may be more effectively removed.
