A cutting device for an electric shaver comprising an outer cutter and a plurality inner blades that are made of a ferrous alloy comprising a substrate of an Fe-Cr stainless steel and a hardened layer of improved hardness and wear resistance. The substrate has a Vickers hardness of 400 or more. The hardened layer has a Vickers hardness of at least 700 and a thickness of 2 to 15 .mu.m. In particular, it is preferred that the hardened layer is a diffusion layer comprising at least 90 vol % of intermetallic compounds of Al and Fe relative to a total volume of the diffusion layer, and Al content included within a depth of at least 2 .mu.m of the diffusion layer is 35 to 65% by weight based upon total weight of a region of the diffusion layer ranging up to the thickness of at least 2 .mu.m. When the ferrous alloy is polished to form the outer cutter and inner blades, it is possible to provide sharp cutting edges of the outer cutter and inner blades, while preventing the occurrence of burrs or micro-chippings at the cutting edges.

摘要:
An image forming apparatus with which the surface potential of the photoreceptor drum is made appropriate reliably in a relatively short time is provided with the following: a charger unit for charging the surface of the photoreceptor drum; an exposing unit for forming a latent image; a potential sensor for detecting a charge potential; and a controller for controlling outputs of the charger unit and the exposing unit. The surface potential of the photoreceptor drum is made appropriate by detecting and correcting the potential after the photoreceptor drum surface is charged at a potential close to a desired potential. After both the dark and bright portions are charged at appropriate potentials, image formation is performed.

An acupuncture needle for treating diseased parts in a patient's body by sticking its needle point into the diseased parts comprises: a needle body which consists of an optical fiber for transmitting light from a light source over nearly the entire length of the needle, and a needle point attached to the front end of the optical fiber; and a means such as a light collecting lens for applying light from the light source onto the end surface of the optical fiber so that the light can be transmitted through the optical fiber. The needle point inserted into the affected part of the body collects light from the light source and radiate light or heat against the affected part, producing improved remedial effects.

Fe-Cr-Ni-Al ferritic alloy capable of forming hot oxidation/corrosion resistive aluminum oxide scale in the surface thereof by exposure to oxidation environments at elevated temperatures. Due to the ferritic structure, the aluminum oxide scale is formed uniformly and densely to improve scale adherence, or prevent scale flaking. The mechanical properties of the ferritic alloy is considerably improved by incorporation of controlled amounts of Cr, Ni, and Al relative to each other, which are added to precipitate minute Ni-Al intermetallic compounds in the alloy matrix while retaining the ferritic structure. Such minute Ni-Al intermetallic compounds are thought to be responsible for improved mechanical properties, including high temperature strength, tensile strength, hardness and the like. Whereby, the alloy combine excellent hot oxidation/corrosion resistance and improved mechanical properties.
摘要:
A ferritic alloy with a wear resistive oxide scale is obtained through the steps of pressing a ferritic alloy powder containing aluminum into a powder compact of a desired configuration, sintering the powder compact in a non-oxidizing atmosphere to provide a resulting sintered product, and heat-treating the sintered product in an oxidizing gas atmosphere in order to precipitate in the surface thereof alumina in the form of an alumina scale as the wear resistive oxide scale which is responsible for improved surface hardness or wear resistance. Due to the inherent porous nature of the sintered product, the oxidizing gas can readily penetrate deep into the surface of sintered product to facilitate the oxidization of the product surface into the alumina scale, in addition to that the oxidization depth can be controlled such as by the density of the product, which makes it possible to readily control the thickness of the alumina scale. The resulting alumina scale has an improved scale adherence due to the ferritic structure of the alloy.
