摘要:
A heat resistant and wear resistant iron-base sintered alloy to be used as the material of a valve seat and a valve face of an engine valve and a waste gate valve of a turbocharger for an internal combustion engine. The iron-base sintered alloy consists essentially of at least one of molybdenum and tungsten, ranging from 3 to 25% by weight, chromium ranging from 1 to 10% by weight, silicon ranging from 0.1 to 0.9% by weight, manganese ranging not more than 0.7% by weight, phosphorus ranging not more than 0.05% by weight, carbon ranging from 0.1 to 2.5% by weight, boron ranging from 0.5 to 2.0% by weight, intermetallic compound of TiAl ranging from 0.3 to 20% by weight, and balance including iron and impurities. In the sintered alloy, carbide, boride and/or carbide boride and TiAl are uniformly dispersed in the matrix, thereby strengthening grain boundary.

A ferro-sintered alloy having wear-resistance at elevated temperatures, comprises a perlite matrix having a copper content of from 0.2 to 1.5% by weight. 10 to 50% by weight of a phase A rich in heat and corrosion resistance is dispersed in the matrix with phase A including 9 to 20% Cr, 6 to 15% Ni, 1.5 to 9.5% Mo, 1.5 to 9.5% W, 0.7 to 4.5 Cu and an Fe remainder. In addition, 2 to 15% by weight of an additional component is dispersed in the matrix which is selected from one of a group of components which are wear-resistant. The group of components comprises:50.about.70% Mo-Fe Alloy (by weight)50.about.70% Cr-Fe Alloy (by weight)45.about.60% Fe-33.about.36% Mo-Si Alloy (by weight)45.about.60% Co-33.about.36% Mo-Si Alloy (by weight).

An endless belt includes a base layer and a resin layer. The base layer includes a metal film. The resin layer is laminated on an outer side of the base layer. The resin layer includes edge portions in an axial direction with at least one edge portion of the edge portions made narrower than the base layer in the axial direction such that the outer side of the base layer is exposed.

An amorphous core transformer is provided which is capable of effectively suppressing influences, fluctuation, displacement or the like of a coil caused by an electromagnetic mechanical force or the like. In an amorphous core transformer 100 including an amorphous core 101, a plurality of coils 102 in which the amorphous core 101 is inserted and a fixing metal frame 110 that assembles the coils 102 and the amorphous core 101, the inter-coil member 106 is interposed between the neighboring coils 102 and the inter-coil member 106 is positioned and held by a positioning member 107. Thus, it is possible to prevent the coils 102 from being deformed or displaced beyond the inter-coil member 106 and maintain the shape of the coils 102.

The aim is to reduce the influence of the filming environment of an image that represents a two-dimensional code when determining a color that has been added to a cell in the two-dimensional code. Disclosed is a two-dimensional code (100) in which a mark is added to each cell group in an information color or a combination color that is correlated with the information indicated by the cell group, and the mark for each cell (C) in the cell group is added in a specified coordinate color within a component domain from among a component model representing the distribution of color components, that is disposed in a positional relationship void of mutual interference.
摘要:
An amorphous transformer which includes an amorphous core formed of an amorphous material with a lap provided at an upper portion and allowed to stand in substantially a vertical direction while being supported at a core support member, and a coil which is fitted with the amorphous core. The core support member is formed by integrating a core support member for supporting a side surface of the amorphous core and a corner support member for supporting a corner portion of the core. The core support member is provided in substantially a vertical direction along at least one of the side surfaces of the core.

An optical access network method, an optical access network and an optical switch for an optical access network, capable of solving all the three problems in the conventional GE-PON: transmission distance problem, security problem and communication interference problem. The optical access network comprises an OLT, a plurality of ONUs and one or more stages of optical switches, which are connected one another. In the direction from the OLT to the ONU, each frame (packet) transmitted from the OLT to one of the ONUs is checked so that only the destination ONU specified in the frame (packet) is connected to the OLT. In the direction from the ONU to the OLT, a control message transmitted from the OLT to one of the ONUs is checked so that only one ONU which has been given a transmission allowance from the OLT is connected to the OLT with respect to each frame (packet).
摘要:
In the energy saving mode, a card I/F circuit section is controlled to turn ON intermittently for a predetermined interval by using a switch. The I/F circuit section supplies electric power to an outside I/F part during the ON interval, and receives some communication data from the outside. When the communication data received by the I/F circuit section is a request for a return from the energy saving mode, a return to the ordinary mode is effected. Therefore, an I/F part, such as a non-contact IC card, requiring external electric power supply can be used as a factor of a request for a return from the energy saving mode. In addition, the energy consumption for that purpose can be reduced.
