Abstract: The object of the present invention is to provide a method for the manufacturing of a cutting material possessing excellent toughness and a high strength. The composition by weight of the Nickel alloy ingot, is chromium (Cr )14-23%, molybdenum (Mo) 14-20%, tungsten (W) 0.2-5%, iron (Fe) 0.2-7%, cobalt (Co) 0.2-2.5% with the remaining portion being made up of Ni and unavoidable impurities. After undergoing a solution heat treatment process, the Ni ingot undergoes plastic working, at a product ratio above 80%, followed by heating at a temperature of 500.degree.-600.degree. C. for longer than 30 minutes. Heating the alloy of the aforementioned composition at the above mentioned temperature promotes the precipitation of an intermetallic compound possessing a hardness greater than 57 on the HRC. The resulting superior cutting material is resistant to corrosion even when exposed to sea water.

Abstract: There is disclosed an alarm clock comprising a vertical mounting plate having an integral battery case at its bottom, the battery case being inwardly rounded to receive a battery therein, a motor mounted to the mounting plate upwardly of and closely to the battery case and electrically connected to the battery, the motor including an output shaft extending parallel to the plane of the mounting plate, a clockwork mechanism fixedly mounted to the mounting plate forwardly of and closely to the motor and the battery case, a gong mounted to the mounting plate upwardly of and closely to the motor, an alarm hammer unit driven by the motor and having an alarm hammer positioned wthin the gong and swung to strike the gong upon actuation of the motor, and an operating lever surrounded by the motor, the clockwork mechanism and the battery case and reciprocable on the mounting plate in the longitudinal direction of the battery case.
