The present invention relates to a reflector for a light-emitting device consisting of (A) an polyamide composition comprising a polyamide polymerized from (a) a dicarboxylic acid comprising at least 50 mol % of an alicyclic dicarboxylic acid and (b) a diamine comprising at least 50 mol % of a diamine with a branched main chain.
摘要:
A masterbatch pellet is provided for obtaining a polyamide resin composition excellent in mechanical strength and heat aging resistance. The masterbatch pellet is obtained by melt-kneading a raw material component containing a thermoplastic resin (A) and a metal oxide (B), wherein a content of the metal oxide (B) is 0.5% by mass or more and a fraction of the metal oxide (B) after the melt kneading is present as an aggregated particle of 5 μm or more in a major axis length. A proportion of the aggregated particle of 5 μm or more in a major axis length in a whole metal oxide after the melt kneading is preferably 30% by mass or less.

摘要:
The present invention enables appropriate behavior of an individual who has problems with memory, and behavior support thereof with certainty. The individual who has problems with memory always carries the portable communication terminal and loads and collects various types of information along with an ID through the communication network as behavior monitoring information. Also various types of provided information (e.g. map information) are collected. When a specific status information (e.g. forgetting the road to take) of the individual who carries the portable communication terminal is loaded, memory support information (behavior support information) is generated by conversation, text and image, so that the specific status where the individual who lost memory cannot take an action to be performed next can be individually dispelled on the spot based on the information collected in the past and various types of provided information, and this memory support information is transferred to the individual carrying the portable communication terminal. In this way, information for dispelling a specific status where an individual who lost memory cannot take an action to be performed next on the spot can be implemented by inference, personally and instantaneously.
