Title: Washing machine
Inventor: HAMAGUCHI WATARU
IPC: D06F33/02
Filed: 1988-11-16
Abstract: PURPOSE:To inform a user of an abnormal water feed within a short time from the water feed starting by making a control means judge a poor water feed and operate an abnormality informing means when the water level is less than a certain fixed water level and the increase amount of water level per unit time is less than a predetermined value in the operation of a water feed valve. CONSTITUTION:A water feed valve 3 is operated to supply water into a washing tank 10. When the water level is lower than a value D predetermined as a limit value, it is regarded as no water feed or a remarkably less water feed amount, and an abnormality information is conducted. When the change of water level to the limit value D or more is observed and the presence of water feed ability is judged, the water feed is repeated until reached to a set water value. A water feed abnormality information can be always conducted even in such a case as the disconnection of a water feed hose on the way, and the submersion of the washing machine disposed place can be prevented. This water level detecting means 8 can not detect the water level until the water in the tank 10 is reached to an air trap 6.

Filed: 1987-11-18
Abstract: PURPOSE:To observe even a thermally unstable amorphous material at an atomic size level, by cleaning the surface of a specimen by the etching using an electrolyte solution and observing the specimen while keeping the surface thereof clean. CONSTITUTION:A needle 2 made of Au is mounted to the leading end of an xyz stage 1 and a specimen stand 3 is arranged in an etching tank 4. Herein, when the chip 7 having an amorphous Si-film formed on an Si-wafer is mounted on the specimen stand 3, since the amorphous Si-film is brought into contact with air in this stage, a SiO2 film is formed to the surface thereof. The etching tank 4 is filled with an aqueous HF solution and, when the needle 2 and a specimen 7 are left for 20sec said solution, the SiO2 film is perfectly removed to expose the amorphous Si-film. Negative voltage is applied to the needle 2 of STM in this state to scan the specimen and, when a tunnel current is detected by an amplifier 5, the surface structure of the amorphous Si-film can be observed by a display apparatus and, since a material having an ionization tendency smaller than that of an etching ion is used in the needle 2, the needle 2 is not etched.

Title: Brazing filler metal and production thereof
Inventor: KASHIWAGI YOSHIYUKI
IPC: B23K35/30
Filed: 1988-11-16
Abstract: PURPOSE:To produce a brazing filler metal of a low temp. and to decrease the thermal influence upon joining material by subjecting specific % of Ag powder and Al powder to a thermal spraying treatment in a nonoxidative atmosphere and forming the powder mixture to a thin sheet shape. CONSTITUTION:The mixture composed of 50 to 80wt.% Ag powder and 20 to 50wt.% Al powder is subjected to the thermal spraying treatment in a nonoxidative atmosphere and is formed to the thin plate shape. the alloy having such compounding ratios is hard and does not elongate but is in the form of the thin sheet; therefore, the alloy allows working such as cutting and blanking. The sheet-like brazing filler metal which is not limited in the points of application is thus easily obtd. In addition, the brazing filler metal has the relatively low brazing temp. of about 650 deg.C at which the thermal adverse influence is low. The thermal influence that this brazing filler metal exerts on the joining members and other constituting members is thus decreased and the well joining of various metallic materials consisting of copper, iron, stainless steel, cobalt alloy, titanium, nickel, etc., is possible.

Title: Sealed alkaline storage battery
Inventor: KAWASE RYUJI
IPC: H01M10/34
Filed: 1988-11-16
Abstract: PURPOSE:To lengthen the cycle life of a battery by using an alkaline aqueous solution whose zincate ion concentration is 0.1-0.6mol/l as the electrolyte. CONSTITUTION:Nickel hydroxide is used as a positive active material and cadmium hydroxide as a negative active material. By using this specified electrolyte, zincate ions in the electrolyte are adsorbed on the surface of the positive active material. As a result, the conversion of nickel hydroxide into gamma-nickel oxyhydroxide during charging is retarded. Decrease in electrolyte held in a separator is thereby retarded, and the cycle life of a battery is lengthened.

IPC: B01D46/10
Filed: 1985-12-25
Abstract: PURPOSE:To reduce dust floating in air and facilitate discarding of dust by disposing a net held by a frame member under the floor of a dust chamber, catching dust having a large sizes by the ne, simultaneously allowing dust having sizes which are smaller than those of the mesh to pass through the net, and discarding dust having larger sizes. CONSTITUTION:When clear air 3 obtained through a filter 2 is ejected so that it blows downward through a dust-proof chamber 1, a floor 6 allows air 3 to flow, and minute dust and waste pieces of thread in the air pass through the floor 6. A filter 7 is mounted on a stay or the like supporting the floor 6 in a freely attachable and detachable manner. While air 3 is ejected, dusts having large sizes such as waste pieces of thread are caught by a net 12 but those having smaller sizes than the mesh pass through the net 12. Accordingly, during the cleaning operation, the entire part of the filter 7 is removed from the stay, and dust caught by the net 12 is discarded, whereby cleaning of dust having large sizes is carried out at once. Thus, the clean degree of clean air can be increased.
