摘要:
It is intended to provide a biodegradable polyester resin composition which is excellent in gas barrier properties, mechanical strength and heat resistance and has Theological characteristics advantageously usable in molding a foamed article, etc., a process for producing the same, and a foamed article and a molded article using the same. The biodegradable polyester resin composition contains 100 parts by mass of a biodegradable polyester resin containing 59% mole or more of a hydroxycarboxylic acid unit, 0.01 to 10 parts by mass of a (meth)acrylic acid ester compound and 0.05 to 20 parts by mass of a layered silicate.

摘要:
A biodegradable resin composition and an object molded or formed from the composition. The resin composition comprises: 100 parts by weight of a biodegradable polyester resin comprising not smaller than 50% by weight of polylactic acid having a melting point of not lower than 160° C., the biodegradable polyester resin having a melt flow rate of 0.1 to 50 g/10 min as measured under a load of 21.2 N at 190° C.; and 0.1 to 20 parts by weight of a phyllosilicate containing a primary, secondary or tertiary amine salt, a quaternary ammonium salt or a phosphonium salt ionically bonded between layers thereof.

摘要:
In a radio communication apparatus having both portable telephone portion and radio paging portion, the portable telephone portion comprises a portable telephone transmission/reception unit 21, a control unit 23, a speech transceiver 25, a display unit 27, and an operation unit 29, while the radio paging portion comprises a radio paging receiver unit 31, the control unit 23, the display unit 27, the operation unit 29, a tone generation announcement unit 33, a silent announcement unit 35, an announcement mode memory 39, and a reception information memory 37. It is assumed that the operation unit 29 selects "a delayed announcement mode after completion of communication" and stores this mode in the announcement mode memory 39. In this event, when the radio paging operation is received during communication of the portable telephone portion, the control unit 23 makes the silent announcement unit 35 carry out call announcement in a silent mode and makes the reception information memory 37 memorize a message. After completion of the communication, the control unit 23 makes the tone generation announcement unit 33 announce reception of the radio paging operation during communication and makes the display unit 27 collectively display the reception information.
