Abstract: PURPOSE:To massproduce highly efficiently an amorphous alloy powder having a uniform particle diameter, by melting a crystalline alloy powder having a uniform particle diameter with the powder dispersed and moved by a gas stream, arresting and solidifying quickly the powder. CONSTITUTION:The crystalline alloy powder 3 made up of particles having a uniform particle diameter of up to 200mum is fed via a feeding port 4 of a hopper 2 into a container 1 while an inert gas or a reducing gas is introduced via a gas introducing inlet 5 of the container 1, so that the gas is mixed with the powder 3 to form a mixed stream, which is jetted in an atomized state from a nozzle 6 into a tubular furnace 7. In the tubular furnace 7, the alloy particles are heated to a temperature 50-500 deg.C higher than the melting point of the alloy, and are melted and delivered. Then the melted alloy particles are arrested by a cooling medium liquid 8 that is being circulated in directions shown by arrows 9, 9', so that they are quickly solidified into alloy particles, which are stored in storing liquid tank 10. Said cooling medium liquid 8 is fed in an amount of 20- 500 times the amount of melted alloy particles to be arrested so that the alloy particles may be quickly cooled.

IPC: H03K3/2897
Filed: 1979-09-19
Abstract: PURPOSE: To make it easy to adjust hysteresis width by providing a Schmitt trigger circuit with an additional current source composed of a current Miller circuit.  
     CONSTITUTION: When potential V 40  at base terminal 40 of transistor 15 rises and the collector current of transistor 15 exceeds I/2 (I is current value of electric power source 12.), the collector current of transistor 11a becomes less than I/2 and the collector current of transistor 11b also becomes less than I/2. Consequently, a difference is generated between the collector currents of transistors 15 and 11b and the difference current flows to bases of transistors 16 and 18, which turn on duddenly. When voltage V 40  falls below V 30  (potential at base terminal 30 of transistors 13 and 14), transistors 16 and 18 turn off similarly. For this purpose, adjusting emitter areas of transistors 13, 14 and 15 of electric current source 11 makes is possible to adjust the hysteresis width.

Title: Gold for electronic parts or gold alloy plating material
Inventor: ASAHARA HAJIME
IPC: C25D3/58
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To improve heat resistance, corrosion resistance and press formability by forming the material which has an alloy plating intermediate layer containing a specific ratio of P in Cu alloy blank and consisting of the balance Cu and inevitable impurities and consists of a surface layer plating of Au or Au alloy. SOLUTION: The intermediate layer contains 0.05 to 15 wt.% P. Or the intermediate layer may contain P and B at 0.05 to 15 wt.% in total. P and B form a stable film in a pinhole part by their own oxidation, thereby suppressing the diffusion of Cu of the blank and the plating layer to the surface layer and substantially preventing the occurrence of the increase in the contact resistance or the degradation in solderability at the time of heating. The thickness of the intermediate layer is preferably set to 0.01 to 1.0 μm. If inserting and removing properties are desired to be improved, the execution of an ordinary sealing treatment by a sealing treating liquid of an organic system or inorganic system is recommended.  The alloy plating of Cu-P of the intermediate layer may be executed by using a bath prepared by adding sodium hypophosphite to a Cu plating bath of a pyrophosphate system as a base.
