Abstract: Disclosed are an absorbent and antibacterial polystyrene paper, a method for producing thereof, and an absorbent and antibacterial tray using the same. The absorbent and antibacterial polystyrene paper according to the present invention may be useful to absorb into a paper liquids, such as blood, moisture and the like, which is generated from foods in packing the foods such as meats, fishes, etc., by adding an antistatic agent to polystyrene raw materials and foaming the resultant mixture to produce absorbent and antibacterial polystyrene paper and tray, wherein a plurality of absorption holes are formed on one surface thereof. Here, the absorbent and antibacterial polystyrene paper according to the present invention is produced by mixing, foaming and extrusion-melting 91 to 95% by weight of polystyrene, 2 to 4% by weight of a nucleating material master batch and 3 to 5% by weight of an antistatic agent master batch, wherein a plurality of absorption holes are formed on a surface of a molded sheet.

Abstract: An LED lamp has: an LED with a pair of terminals; a holder to which the LED is attached, the holder being of insulating material; and a radiation unit that has two metallic radiation plates that are attached to the holder while surrounding the holder and being insulated from each other. Each of the radiation plates has a contact portion that contacts the pair of terminals of the LED being attached to the holder and a power receiving terminals for power supplied to the LED.

Abstract: A vibration actuator for effecting paging is provided in which a vibrating section of an electroacoustic transducer is driven using low frequencies to collide it against a fixed section, and the vibration generated from the collision is transferred as external vibration. The vibrating section of a coil and the fixed section are bonded via an elastic member provided therebetween. The vibration generated at the time of collision can be effectively increased by flexibly supporting a magnetic circuit composed of a magnet, a yoke, etc. and by driving the magnetic circuit with alternating current which has a polarity. To permit easier assembly and to prevent damage or deterioration in characteristics, it is preferable to provide an annular molded member, which has hook-like projections, around the magnetic circuit and to support the magnetic circuit by a rubber member attached to the hook-like projections.
