A nickel material, which comprises by mass percent, C: 0.003 to 0.20% and one or more elements selected from Ti, Nb, V and Ta: a total content less than 1.0%, the contents of these elements satisfying the relationship specified by the formula of “(12/48) Ti+(12/93) Nb+(12/51) V+(12/181) Ta—C≧0”, with the balance being Ni and impurities, does not deteriorate in the mechanical properties and corrosion resistance even when it is used at a high temperature for a long time and/or it is affected by the heat affect on the occasion of welding. Therefore, it can be suitably used as a member for use in various chemical plants including facilities for producing caustic soda, vinyl chloride and so on. Each element symbol in the above formula represents the content by mass percent of the element concerned.

A system analyzing apparatus obtains a message group including a message ID, a protocol, a type, and a transmission time of messages transmitted/received in a system where a hierarchical structure of protocols is defined. The apparatus detects pairs of a request message and a response message of the same message ID from the obtained message group. The apparatus identifies a request time and a response time of each of the detected pairs. The apparatus searches for a child-layer pair that has a request time and a response time between the request time and the response time of a parent-layer pair arbitrarily selected from among the pairs and that has a protocol in a layer lower than the protocol of the parent-layer pair on the basis of the identified result. The apparatus outputs the found child-layer pair as a candidate pair having a call relationship with the parent-layer pair.

The present invention provides a duplex stainless steel having excellent resistance to alkalis and particularly corrosion resistance against high-temperature concentrated alkali solutions and excellent weldability. The duplex stainless steel has a chemical composition comprising, in mass %, C: at most 0.03%, Si: at most 0.5%, Mn: at most 2.0%, P: at most 0.04%, S: at most 0.003%, Cr: at least 25.0% to less than 28.0%, Ni: at least 6.0% to at most 10.0%, Mo: at least 0.2% to at most 3.5%, N: less than 0.5%, W: at most 3.0%, and a remainder of Fe and impurities.
摘要:
An air conditioner outlet vent device in which one of a blade and a housing is molded as a primary molding having a shaft hole by primary injection using a first synthetic resin, the other is molded, within a secondary mold die where the primary molding has been set, as a secondary molding having a support shaft by secondary injection using a second synthetic resin so that the shaft hole and the support shaft are fitted together at the same time as they are molded, thereby enabling the blade to pivot within the housing. The first and second synthetic resins are of the same synthetic resin system, and an additive for suppressing shrinkage in cooling and solidifying it after injection molding is added to the first synthetic resin so that the percentage mold shrinkage of the shaft hole becomes smaller than that of the support shaft.

A baby carrier used for holding a baby in both face-to-face and forward-facing manners includes a carrier body 10 for accommodating a body of a baby and a wearing member 30 secured to the carrier body 10 for wearing the carrier body on a body of a user. The carrier body 10 includes at least a back rest 11 and is capable of accommodating and holding a baby in both a face-to-face holding manner in which the baby is held such that the back rest 11 is brought into contact with the back of the baby and a forward-facing holding manner in which the baby is held such that the back rest 11 is brought into contact with the chest and abdomen of the baby. The back rest 11 includes a width-reducing member 50 for reducing a width of a lower portion of the back rest 11, to be located between legs of the baby when the baby is held in a forward-facing holding manner.

A baby carrier having a pad of the present invention comprises a carrier body 10 including at least a back rest 11 and capable of accommodating and holding a baby in both a face-to-face holding manner in which the baby is held such that the back rest 11 is brought into contact with a back of the baby and a forward-facing holding manner in which the baby is held such that the back rest 11 is brought into contact with chest and abdomen of the baby; and shoulder belts 30 and 30 mounted to the carrier body 10 and carried on left and right shoulders; wherein the baby carrier further comprises a pad 40, which can cover the back rest 11, mounted detachably in the carrier body 10, formed wider than a portion which corresponds to a crotch rest portion of the back rest 11 of the carrier body 10 when the carrier body is used in the forward-facing holding. With this structure, it is possible to safely and comfortably hold the baby in any of the face-to-face and forward-facing directions, and to carry the baby laterally and piggyback.

A waist bag usable as a baby holder includes a waist bag body capable of supporting the weight of a baby seated thereon and a waist belt secured to the waist bag body for fixing the waist bag body to a user's waist. A shoulder strap is capable of being suspended from the user's shoulder or neck when the user holds a baby seated on the waist bag body. Both ends of the shoulder strap are connected to the waist bag body. An auxiliary strap is bridged across the shoulder strap for holding an upper part of a baby. A distance between the auxiliary strap and the waist bag body can be adjusted at both ends of the auxiliary strap, independently. Therefore, a baby can always be held by the auxiliary strap despite the baby holding position, the physique of the user or the physique of the baby.
