Abstract: A polylactic acid foam of beautiful appearance excelling in heat resistance and having satisfactory mechanical properties is provided from polylactic acid and a polyolefin resin and further a vinyl-carboxylate-modified polyolefin resin. The polylactic acid foam is characterized in that not only 1 to 80 parts by weight of polylactic acid but also vinyl-carboxylate-modified polyolefin is contained in 100 parts by weight of polyolefin resin containing 50 wt. % or more of polypropylene resin.

Abstract: The interior material article for an automobile of the present invention comprises sequentially a skin layer (A), a crosslinked foam layer (B) and a base layer (C), and is composed of an integrated combination of a laminated sheet in which the skin layer (A) and the crosslinked foam layer (B) are joined and the base layer (C) by vacuum molding method. The skin layer (A) comprises a polyolefin-based resin (a1), and the crosslinked foam layer (B) is a layer in which a crosslinking and foaming resin composition is crosslinked and foamed, the composition comprising a polylactic acid-based resin (b1), a polyolefin-based resin (b2) comprising a monomer unit based on ethylene and a monomer unit based on propylene, a modified polyolefin (b3) having an ester bond at its side chain, and a crosslinking aid (b4).

Abstract: The invention relates to polylactic acid foam comprising a resin composition that comprises polylactic acid (A), polyolefin resin (B) and a polyolefin resin copolymer (C) wherein the weight ratio of the polylactic acid to the sum of the polyolefin resin and polyolefin resin copolymer in the resin composition, (A)/{(B)+(C)}, is in the range of 0.2-6. The polylactic acid foam used is low in the load in global environment and high in heat resistance, moldability and compression strain recovery, and this polylactic acid foam can be applied to a wide variety of uses where polyolefin resin foam has been used conventionally, including interior members of vehicles, heat insulator, cushioning medium, packing material, base of pressure sensitive adhesive tapes, and joint filler for tiles.

Abstract: A monitoring apparatus (3) which is used to monitor the channel actually selected by a TV set (1). A reference tuner (32) independently reproduces and output an audio signal of the channel to be monitored. An audio comparison part (31) compares the feature parameter of an audio signal from a loudspeaker output terminal (13) of the TV set and the feature parameter of the audio signal from the reference tuner to detect whether or not the both signals coincide with each other. A remote control signal receiving part (34) receives a signal from a TV remote control signal transmitter (2) to obtain information of a channel to be switched to. At the time of changing the channel of the reference tuner until coincidence is detected in the audio comparison part, a control part (37) indicates first to the reference tuner the channel to be switched to identified by the remote control signal part, thereby permitting fast and accurate monitoring of the channel being selected by the TV set.

Abstract: A television channel selection monitoring apparatus for identifying the broadcast channel to which a television receiver means is tuned at any given time is disclosed. Instead of relying for the channel identification on the local oscillation frequency at the tuner of such television receiver means, the apparatus of the present invention utilizes the recognition of the channel identification number superimposed on the video signal received through the selected channel so that the image of the superimposed channel number may appear, for a certain duration following the channel selection, at a predetermined area of the image corresponding to the video signal.
