Title: Cleaning method of metal super fine powder
Inventor: SAITO KAN
IPC: B22F9/28
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To clean a large quantity of a sample with a small quantity of a cleaning liquid for a short time, to enable to apply also for a water insoluble halide and to suppress the dissolution loss due to the oxidation of the metal powder itself by cleaning with an organic acid aq. solution heated to a specific temp. in a specific range of a solid-liquid ratio. SOLUTION: The organic acid aq. solution is added in an untreated metal super fine powder. The organic acid concentration in the organic acid aq. solution is preferably controlled to 0.03-0.3 mol/l. The solid-liquid ratio, that is a ratio by weight of the metal super fine powder to the solvent portion in the organic acid aq. solution, is controlled to 1:5 to 1:1. Next, the cleaning is performed by stirring for 20-30 min while heating. High cleaning effect is attained by keeping the temp. of the aq. solution to 60-80 deg.C. Ultrasonic or mechanical cleaning is used for the stirring and the stirring time is about 20 min and it is sufficient to stir 1-2 times. The cleaning is desirably performed in a reduced pressure or an inert gas atmosphere. After cleaning, the purified powder is separated from the organic acid aq. solution by filtration.

IPC: G06F1/08
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To attain a compact and light-weight structure of an information equipment for its portable use and also to secure a set-up operation of the same software as a desk-top type and the compatibility of data by taking an inside module out of an outer casing in a portable mode to separate a function equal to that secured while the module is kept in the casing. SOLUTION: An inside module is kept in a small casing, and a portable display part 1a consists of a compact LCD, etc. A display switching part 2 is connected to a display part 1 and the part 1a or a display connection terminal part 16 when the inside module is set in and taken out of the outer casing respectively. A portable input part 5a is independent in terms of its function but uses a touch panel unified with the part 1a and is controlled by an input control part 6. Thus, the inside module stored in a small casing of an information equipment can have the same function as that of a notebook or desk-top type information equipment even if it is taken out of the casing.
