Title: Composition for solder paste
Inventor: ISHII GINYA
IPC: B23K35/02
Filed: 1983-06-30
Abstract: PURPOSE:To obtain a solder paste which is hardly oxidizable after coating until soldering with the solder paste for a printed wiring board by limiting the particle size of solder powder. CONSTITUTION:Solder powder having a particle size larger than 5mu is used to form a compsn. for a solder paste. If the solder powder having the larger particle size is used in such a way, the compsn. is made stable to air oxidation. The effect of preventing the oxidation is remarkable perticularly when the coated solder paste is dried by hot wind. However if the particle size of the solder powder is too large, the coatability in the stage of, for example, printing the paste is poor and therefore the adequate partizle size is about 150mu in max. in said respect.

Title: Fe-ni alloy having good plating property and solderability
Inventor: NEMOTO RIKIO
IPC: H01J29/07
Filed: 1985-06-03
Abstract: PURPOSE:To obtain an Fe-Ni alloy having excellent plating property and solderability while maintaining the basic properties of the Fe-Ni alloy by incorporating a prescribed ratio of B into the specifically composed Fe-Ni alloy. CONSTITUTION:This Fe-Ni alloy contains <=0.05% C, <=0.03% N, <=2.0% Si, <=3.0% Mn, <=1.0% Cr, >=25% Ni and 0.002-0.02% B, contains, if necessary <=6.0% Mo and/or <=20% Co and consists of the balance Fe. The above- mentioned Fe-Ni alloy is further incorporated therein with 0.005-0.4% >=1 kinds among Nb, Ti, Zr and Al. The oxygen-enriched layer on the surface of the above-mentioned B-contg. alloy produced by annealing in an ordinary non-oxidizing atmosphere is fairly thin and the B is concd. in the surface layer. The uniform B nitride layer is formed in the surface layer in the non-oxidizing atmosphere. The surface thickening of the other components is therefore suppressed and the oxide layer is hardly formed. The autoreduction of the oxide film arises in a plating liquid. The adsorption of the nuclei of plating is liable to arise and the plating property is improved.

Title: Hydrogen detecting system
Inventor: HARIMA KAZUHIKO
IPC: H01M8/04
Filed: 1994-05-31
Abstract: PURPOSE:To obtain a hydrogen detecting system at a low cost, which can accurately detect the leakage quantity of hydrogen, by measuring the quantity of the moisture generated from the hydrogen component leaked from a device for treating hydrogen inside thereof (fuel cell or the like). CONSTITUTION:In the case where hydrogen is leaked from a fuel cell 1, hydrogen and the purged inert gas exist in a container 3. Such a gas inside of the container 3 is discharged outside through a pipeline. At this stage, a part of the gas is taken to the branch passage 4 side by a suction pump 5, and mixed with the air by an ejector 6, and supplied to a hydrogen reaction unit 7. In the hydrogen reaction unit 7, hydrogen in the mixture gas is burned with the catalyst so as to form the water. The gas, of which hydrogen component is converted to the water in the reaction unit 7, is supplied to a hydrometer 8 by the sucking force of the pump 5. The hydrometer 8 measures humidity of the supplied gas. Since the quantity of hydrogen is detected on the basis of the moisture quantity, hydrogen can be detected at a low cost without using an expensive hydrogen gas sensor for measuring the quantity of hydrogen on the basis of the heat to be used for burning the hydrogen.

Title: Bonding apparatus
Inventor: NAKAJIMA MAKOTO
IPC: H01L21/60
Filed: 1986-05-26
Abstract: PURPOSE:To avoid oxidization of an object to be bonded by a method wherein the object to be bonded is covered by a fixed cover and gas is supplied to the inside of the fixed cover. CONSTITUTION:If a group of lead frames 3 which are arranged in one row along the before-and-behind direction is aligned in the hollow part of a lead frame pressing member 20, a multi-lead frame 3A is stopped intermittently. Then, if the lead frame pressing member 20 is descended to press the outer circumferential parts of the respective groups of the lead frames 3, as reductive gas is being spouted out from a group of spouting outlets 23, the lead frames 3 are exposed in a reductive gas atmosphere. At that time, as the reductive gas atmosphere is covered by a fixed cover 18 and a movable cover 24, the atmosphere can be formed efficiently. It is to be noted that, although the small window 27 of the movable cover 24 is aligned directly above the lead frame 3 to be bonded first and opened, as the opening area is small, the leakage of the gas through the small window can be minimized.
