摘要:
A (Nb, Ti) phase in an Nb—Ti—Co alloy is composed of a granular structure. The Nb—Ti—Co alloy is preferably subjected to heat treatment at 800° C. or more so that the eutectic structure in the casted state can be changed to a granular structure. The Nb—Ti—Co alloy used there is preferably NbxTi(100-x-y)Coy, (x≦70, 20≦y≦50 (mol %)). By properly predetermining the heating temperature and time, the resulting alloy exhibits improved hydrogen permeability in combination with a good hydrogen embrittlement resistance characteristic in the CoTi phase, making it possible to provide a practical hydrogen permeable membrane having an advantageously high performance.

摘要:
Disclosed are a silicon carbide sintered body and a sliding component using the same, and a protective body which, even when fine cracks are generated due to thermal shock or mechanical impact over prolonged use, are capable of inhibiting development of the cracks. The silicon carbide sintered body contains silicon carbide grains as a major component and has a relative density of 95% or more. On an observation surface of the silicon carbide sintered body, coarse silicon carbide grains 1b having a surface area of 170 μm2 or more occupy 6 area % or more and 15 area % or less. The silicon carbide sintered body has excellent mechanical properties such as strength and rigidity. Even when fine cracks are generated due to thermal shock or mechanical impact, coarse silicon carbide grains 1b are capable of inhibiting development of the cracks.

摘要:
An overhead shuttle is controlled to support a bottom of an article while traveling. A transfer apparatus is controlled to hold the article from above the article, move the article between a position above the overhead shuttle and a position above stations provided on a side of a travel rail, and elevate and lower the article to transfer the article between the transfer apparatus and the station.

To provide a power generation member having a high power generating capacity, a power generation device using the same, and a power generation system.A power generation member 1 includes: a piezoelectric element 2 in which electrodes 2a and 2c are formed on both main faces of a plate-shaped piezoelectric ceramic 2b; a pressing member to press one main face of the piezoelectric element 2; and a support member 4 to support the other main face of the piezoelectric element 2, wherein the support member 4 supports an outer rim of the piezoelectric element 2, and the pressing member 3 presses the piezoelectric element 2 at a part inside the support member 4 with a planar pressing face. It is possible to reduce cancellation of the generated charge, as well as to allow the piezoelectric ceramic 2b to deform sufficiently to produce large strain by pressure energy generated by a walking man or vibration energy generated by a running car and the like. As a result, it is possible to effectively obtain large electricity.

In an image communication system for compositing and generating an image for enhancing the communication, a composite image generator in a communication terminal analyzes voice data and image data, and an analyzer analyzes voice data to detect an emotion parameter. Basic emotion data are generated by a movement controller, an emotion movement pattern storage and a basic emotion generator, based on the emotion parameter. An expression compositor composites the basic emotion data with expression data, extracted from image data, to generate composite expression data. An image compositor composites the composite expression data with character data to generate a composite character image.

A resilient contact member to be installed in a jack for use in conjunction with a pin-plug comprising a fixed leg portion to be fixed to an inner wall of a housing of the jack, a movable leg portion having a portion which is to be engaged with a pin portion of the pin-plug inserted into the jack to make an electrical connection between the jack and pin-plug, a substantially U-shaped portion for connecting the fixed and movable leg portions to each other at their one ends, said fixed and movable leg portions extending in parallel with each other. The fixed and movable leg portions and U-shaped portion are all formed integrally with each other by punching a thin metal plate. The contact member further comprises a reinforcing member which engaging with the movable leg portion. The movable leg portion can be moved toward the fixed leg portion in a resilient manner against the resilient force of the movable leg portion and the reinforcing member.
