摘要:
A film is formed on the surface of a soft metal portion (2) such that the film contains phosphorus and either platinum or palladium, and further, at least one element having homogeneous solubility with platinum or palladium, with the content of the phosphorus being in a range of about 15 to 25 atomic %, or contains boron and iron with the content of the boron being in a range of from about 15 to 25 atomic %. Thus, a soft metal is made up by turning the film into a hard layer (3) made of an amorphous alloy.

A decorative part comprising a hardening layer having a pink Au alloy coating film on a surface of the part. The hardening layer is obtainable by laminating a base layer, a primary layer and a finishing layer from the side of a substrate. The base layer comprises a metal layer comprising one metal or two or more metals selected from Hf, Ti and Zr and, superimposed thereon, a compound layer comprising the same metal constituting the metal layer and further comprising nitrogen, carbon or oxygen. The primary layer has a laminating structure such that an Au alloy layer, and a compound layer comprising one metal or two or more metals selected from Hf, Ti and Zr and further comprising nitrogen, carbon or oxygen are laminated one after the other. The finishing layer comprises an Au alloy layer.

A method for measuring a directional of a body in a three-dimensional space defined by an X-axis (magnetic north), a Y-axis, and a Z-axis is proposed. A geomagnetic force along an x-axis, which is the direction towards which the body points and an x-axis tilt angle, which is an angle between the horizontal plane and the x-axis, are detected. The x-axis tilt angle is determined as a rotation angle, which an angle by which the x-axis needs to be rotated around the Y-axis so as to be in the XY-plane. An azimuth of the body is calculated from the geomagnetic force and the rotation angle.

A soft metal and a decorative article of wristwatch are produced by forming, on the surface of a soft metal article (2), a hard layer (3, 13) containing zirconium and molybdenum, or containing zirconium, molybdenum and further an additive element constituted of at least one or more elements selected from niobium, tantalum, and titanium. It is preferable that the content of molybdenum constituting the hard layer (3, 13) is about 30 to 75 wt %, or that the content of molybdenum is about 25 to 65 wt % and the total content of the additive elements is about 25 wt % or less.
摘要:
A multimedia signal processing apparatus comprises communication service units having a plurality of types of signal processing modes corresponding to a plurality of types of communication service classifications, a communication service classification identifying unit for identifying, on the basis of signal processing request information on one call communicated from a higher-rank node, a communication service classification for that call, and a mode control unit for controlling a signal processing mode of the communication service unit to a mode suitable for the communication service classification identified in the communication service classification identifying unit. With this configuration, in the multimedia signal processing apparatus, the signal processing mode of the communication service unit is controlled to a mode suitable for the service classification for each call, which can considerably decrease the number of communication service units to be mounted and significantly reduce the probability of the rejection of newly arrived call.
摘要:
A wristwatch case (11) and a method of manufacturing the case, the wristwatch case comprising a wristwatch case body (1) made of titanium or stainless steel and a crown pipe (3) fixed to each other, wherein a stem hole (2) corresponding to the crown pipe (3) is formed in the wristwatch case body (1), a small diameter part is formed in the crown pipe (3), and a small diameter part corresponding to the a small diameter part of the crown pipe is formed in the stem hole (2), the method comprising the step of fitting the crown pipe (3) into the stem hole (2) in the wristwatch case body (1) to form a solid phase diffusion joining part at a portion where the small diameter parts thereof are fitted closely to each other, and to form a brazed connection part at a portion other than that where the small diameter parts are fitted closely to each other, whereby a watch external part having excellent corrosion resistance and waterproof and a large number of design variations can be provided.
摘要:
One wristwatch case, wherein a pipe is fixedly connected thereto and a connection interface between the wristwatch case and the pipe is not present substantially; the method of fixing the wristwatch, comprising the steps of providing a through-hole in the wristwatch case, press fitting the pipe of 0 mm or larger in press fitting tolerance (pipe outer diameter—through-hole diameter) between the through-hole and the pipe, and heating the wristwatch case after the press fitting step; the other wristwatch case, wherein a pipe is fixedly connected thereto through a diffusion layer; the method of fixing the pipe of the wristwatch case, comprising the steps of forming a through-hole in the wristwatch case, press fitting the pipe of 0 mm or larger in press fitting tolerance (outer diameter of pipe having a metal film formed on the surface thereof—diameter of through-hole) between the through-hole and the pipe having a metal film formed on the surface thereof, and heating the wristwatch case in vacuum or reducing gas atmosphere after the press fitting step.
摘要:
A Metal-In-Gap head is disclosed. A barrier layer of iron-silicon alloy is formed on a surface of a gap side of a core, and a sendust layer is formed on the surface of the barrier layer. A gap layer of nonmagnetic material is disposed between the surface of the sendust layer and a surface of another core.
