Abstract:
A magnesium alloy of the present invention includes magnesium as a main component, boron of 0.0005 weight % or more, manganese of 0.03 to 1 weight %, and substantially no zirconium or titanium. This magnesium alloy may further include aluminum of 1 to 30 weight % and/or zinc of 0.1 to 20 weight %. Because of appropriate amounts of boron and manganese contained in the magnesium alloy, the grain of the mangnesium alloy is refined.
Abstract:
An aluminum alloy according to the present invention includes from 4.0 to 6.0% Mg, from 0.3 to 0.6% Mn, from 0.5 to 0.9% Fe, and the balance of Al and inevitable impurities when the entirety is taken as 100% by mass. By appropriately selecting the composition range of Mg, Mn and Fe, it has been possible to micro-finely crystallize Al (Mn, Fe) compounds while inhibiting the growth of primary-crystal Al. As a result, the resulting aluminum alloy is good in terms of the castability, and shows high strength as well as high ductility.
Abstract:
Disclosed are an aluminum alloy casting having a high strength and a high toughness, and a production process for the same. The aluminum alloy casting comprises silicon (Si) in an amount of 2.5 to 4.4% by weight, copper (Cu) in an amount of 1.5 to 2.5% by weight, magnesium (Mg) in an amount of 0.2 to 0.5% by weight and the balance of aluminum (Al), and a matrix thereof includes a dendrite which has a size of 30 micrometers or less. Since the Si addition amount is suppressed as less as possible and since the size of the dendrite is micro-fined in the aluminum alloy casting, the toughness is improved remarkably. Further, since the Cu and Mg are added in the predetermined addition amounts, the strength is enhanced in the aluminum alloy casting. In addition, a solution treatment which is employed in the production process can further enhance the strength of the aluminum alloy casting.
Abstract:
A contact includes a plate with a width that ranges from 0.1 mm or more to 1 mm or less, and a stress concentrated place, where a surface roughness (Ra) on the stress concentrated place is 0.2 μm or less. When samples whose surface roughness Ra is 0.040 μm, 0.080 μm, 0.120 μm, and 0.180 μm were used to study a number of repetitive fracture times, as the surface roughness Ra was smaller, the number of repetitive fracture times became larger. Particularly, it is found that the surface roughness Ra may be 0.200 μm or less in order to satisfy 3000 times as a number of operating times of the battery connector. Further, the surface roughness Ra may be 0.080 μm or less in order to satisfy 6000 times as the number of operating times when a safety factor is 2.

A hitless path switching ring network capable of switching from a work transmission line to a protection transmission line without instantaneous hitting of a signal when a failure occurs in the work transmission line. In the hitless path switching ring network, a node device includes a first memory section storing a signal being transmitted onto the work transmission line during normal operation, and a first read control section, at the time of failure occurrence, reading out the transmitted signal, held before failure occurrence, from the first memory section and sending out the transmitted signal through the protection transmission line in the opposite direction from the transmission direction employed before failure occurrence. Another node device includes a second memory section for storing the signal received through the work transmission line during normal operation, a third memory section for storing the signal received through the protection transmission line during failure occurrence, and a phase adjusting section for matching the time phase of the received signal in the second memory section with the time phase of the received signal in the third memory section and outputting the received signal held before failure occurrence.
Abstract:
A pair of electrode substrates are combined with a sealing material and spacers therebetween. A cell gap of a liquid crystal display element is controlled by maintaining the pressure in the space between the pair of electrode substrates at a predetermined pressure for a period of time as part of an evacuation process for the pair of electrode substrates, and pressing the pair of electrode substrates with atmospheric pressure. This prevents a sealing edge from becoming irregular due to bubbling of the sealing material, thereby providing the liquid crystal display element thus obtained with good linearity in the sealing edge. Moreover, since movement of the spacers near an exhaust port is prevented, irregular display coloring is eliminated, which enables the liquid crystal display element to have good display characteristics. Furthermore, since the sealing edge does not become irregular, the liquid crystal display element has excellent uniformity in the cell gap.
