Title: Titanium series hydrogen storage alloy and electrode for secondary battery
Inventor: MAEDA HISASHI
IPC: H01M10/30
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To obtain a hydrogen storage alloy of high capacity having a long service life, good in high efficiency dischargeability and suitable as an electrode material for a secondary battery at a low cost by composing it of a Ti-Fe-Ni ternary alloy having a specified compsn. and regulating the average grain size of B2 phases to specified value or below. SOLUTION: The compsn. of this alloy is expressed by the general formula of Ti1-x-y Fex Niy , where (x)=0.3 to 0.5 and (y)=0.01 to 0.10. The smaller the grain size of each phase composing this alloy is regulated, the better its dischargeability is made. Namely, the area of B2 phases as the main hydrogen occluding phases to come in contact with Ti2 Ni phases as the outlets and inlets of hydrogen (boundary area) increases, the absorption and discharge of hydrogen are made easy to occur, by which the hydrogen occluding capacity of the B2 phases can sufficiently be utilized. Particularly, by regulating the average grain size of the B2 phases to <=20 μm, both of the discharge capacity and the service life of an electrode improve, and moreover, the high efficiency discharge therein is also improved. The discharge capacity is equal to that obtd. from an expensive rare earth alloy.

Abstract: PURPOSE:To manufacture a whisker preform with a desired shape having good shape retainability by filling slurry in which whiskers are dispersed into a die, subjecting the slurry to freezing treatment while pressurizing is executed, molding it and thereafter removing the frozen moisture. CONSTITUTION:Whiskers are uniformly dispersed into water to form slurry in which the volume content of the whiskers is regulated to about 10 to 40%. This slurry is, as it is or in the finely frozen state, filled into a die. The slurry is subjected to freezing treatment by using a refrigerant such as liquid hydrogen while pressure is applied to the die, and the slurry or finely frozen grains are integrally molded. The molded body is released from the die as is in the frozen state to remove the frozen moisture. The removal of the frozen moisture is preferably executed, e.g. by the method of reducing the pressure to the degree of vacuum in the vicinity of 1mmHg at <=0 deg.C and performing sublimating and drying. In this way, a whisker preform having a complicated shape can easily be formed.

Title: Formation of silicon film
Inventor: MEGURO TAKASHI
IPC: H01L21/268
Filed: 1984-05-14
Abstract: PURPOSE:To form locally a silicon film at a given portion at a high film-forming rate, by irradiating CO2 laser light to a substrate being placed in a source gas atmosphere at a low angle and by irradiating Ar<+> laser light to a portion of the substrate being irradiated by the CO2 laser light at an approximately right angle. CONSTITUTION:CO2 laser light 2 is irradiated at a low angle theta to a substrate 1 which is being placed in a SiH4 source gas atmosphere and Ar<+> laser light 4 which is focused by a lens 3 is irradiated near the beam center at which the CO2 laser light 2 has the most intense strength. In this way, on the surface portion of the substrate 1 which is being irradiated by the beam center and the vicinities with the most intense strength of CO2 laser light 2, the source gas can be decomposed most efficiently and thus the resulted temperature rise of the substrate 1 can form a film efficiently. Moreover, since the energy of the CO2 laser light 2 is not absorbed by the substrate owing to the low angle incidence, the substrate 1 can be heated locally by the focused Ar<+> laser light 4.
