The present invention provides a method for analyzing the C-terminal amino acid sequence of a peptide by applying reaction technique for successively releasing the C-terminal amino acids therefrom, which method can suppress, when releasing the C-terminal amino acids of the peptide in sequence, such as an undesirable side reaction as cleavage of peptide bond in the intermediate position of the peptide, and allows to carry out the chemical treatment thereof under widely applicable conditions. In the method according to the present invention, an alkanoic acid anhydride and a perfluoroalkanoic acid both of vapor phase, which are supplied from a mixture containing an alkanoic acid anhydride with a small amount of a perfluoroalkanoic acid added thereto, are allowed to act on a dry sample of the peptide to be examined in a dry atmosphere at a temperature chosen in a range of 15 to 60° C.; whereby the release of the C-terminal amino acid is resulted from successive formation of a 5-oxazolone structure being followed by cleavage of the 5-oxazolone ring; and then the C-terminal amino acids sequence is identified by analysis based on the decrease in molecular weight in a series of the reaction products obtained.

An object of the present invention is to provide a single-phase film of a metal sulfide with good quality, and a method for preparing a metal sulfide film at a low cost in a convenient manner. The present invention provides a preparation method of a metal sulfide film, comprising the steps of providing metal halide, such as iron halide (FeCl3, FeI3, FeBr3, FeCl2, FeI2 and FeBr2), as a first raw material and a thioamide compound, such as thioacetamide, as a second raw material, preferably vaporizing these raw materials and reacting them at atmospheric pressure; and a metal sulfide film prepared by this method.

When a MOS transistor is turned off, a forward current flows into a diode connected to the MOS transistor. When the MOS transistor is conducted, a reverse bias is applied to the diode. When the MOS transistor is turned on during the reverse recovery time of the diode, a short-circuit current flows into the MOS transistor, the diode, and a battery connected in series with the diode and the MOS transistor. In this case, an overcurrent flows through the wiring of the battery momentarily, and electromagnetic wave generates from the wiring. Accordingly, noise caused by the electromagnetic wave is generated in an antenna to a radio receiver. The drain current of the MOS transistor is gradually increased by a delay circuit, and the MOS transistor is shifted from a completely turned-off state to a completely turned-on state with a time period longer than a reverse recovery time of the diode. Consequently, no reverse current flows through the diode. Therefore, a short-circuit current is prevented from flowing through the battery, the diode, and the transistor, and no noise is generated in the receiver.

This invention is to enable inter-domain routing using MPLS. When communication is carried out passing through plural domains, respective management servers managing respective domains cooperate to carry out path constitution and optimum routing. At the path constitution, the respective management servers connect links within the respective controlling domain to constitute paths to reach a target address. When the paths are constituted, label data is notified to nodes associated with the constituted paths, and isused at the routing. At the routing, the management server controlling the source domain obtains the dynamic transmission bandwidths from the respective management servers, and identifies the routing policy from a port number of a request to be routed or the like to identify the optimum path. When the optimum path is determined, it is possible to carry out the routing using the label data held in the respective nodes.

This invention is to provide a technique enabling efficient routing in the entire network by totally viewing a state of the entire network from a specific server. An information processing method for managing paths between arbitrary nodes in a specific network according to the invention, includes: obtaining data concerning a utilization state of each link constituting a path, from associated nodes in the specific network; and calculating a value of dynamic transmission bandwidth in an entire path by using the data concerning the utilization state of each link constituting the path, and storing the calculated value into a management data storage. By the dynamic transmission bandwidth, that is, bandwidth, which can actually be used for communication to be carried out from now, it becomes possible to carry out efficient routing.

A process for recycling a thermoplastic resin covered with a thermosetting-resin paint film includes the steps of decomposing the paint film by bringing the thermoplastic resin covered with the paint film into contact with a paint-film-decomposing agent in a molten state, and removing decomposed products, resulting from the paint film and the paint-film-decomposing agent, and the residual paint-film-decomposing agent by degassification to prepare a recycled resin. The paint-film-decomposing agent can be primary amines and/or secondary amines having a boiling point of 250.degree. C. or less, or being decomposed at 250.degree. C. or less, or can be tertiary amines and/or quaternary amines having a boiling point of 250.degree. C. or less, or being decomposed at 250.degree. C. or less to which water and/or alcohols is added.
摘要:
With respect to methods of connecting two or more members where at least one of them comprises a resin member, there is provided a method of connecting members that is capable of firmly connecting two or more members with a rivet without causing the matrix resin to crack even when a joining method that uses a self-pierce rivet is applied to the connecting method. The method of connecting members is a method of connecting members in which overlapping portions of two or more members are connected, the method comprising: disposing a resin member, whose matrix resin comprises a thermoplastic resin, at at least a bottom layer forming the overlapping portions; and, with the matrix resin melted by heat treating at least the resin member of the overlapping portions, driving in a self-pierce rivet from above a member at a top layer of the overlapping portions so that it reaches an interior of the resin member, and connecting the overlapping portions by curing the matrix resin.
