    摘要: Disclosed is a method for recovering acrylic resin from an excess of a sprayed powder coating composition. An excess of the powder coating composition which is not deposited onto an article to be coated and is recovered in a coating apparatus is dissolved in an aromatic hydrocarbon solvent which dissolves the acrylic resin component and which has a solubility of a curing agent of not more than 1.0 g (curing agent)/100 g (solvent) at 20.degree. C. and the acrylic resin component is recovered from the resin solution. The acrylic resin component thus recovered can be reused as a resin component for coating compositions.

    摘要: An antenna for mounting on a vehicle which restrains damping of a signal voltage by reducing a stray capacitance of a signal path and has an improved antenna characteristic and a short physical length, and an antenna element which is suitable for an antenna for mounting on a vehicle and is flexible by using a helical coil of a large winding diameter are provided. In the antenna for mounting on a vehicle, with respect to a band signal having a short wavelength of a plurality of band signals to be transmitted/received, an antenna element is caused to resonate with a physical length shorter than ¼ of the wavelength of the band signal. A linear line portion is provided at the proximal end, and the antenna element is provided at a predetermined distance from vehicle body and a conductive member of the same electric potential as the vehicle body. The stray capacitance between the proximal end portion of the antenna element and the vehicle body is small, and a signal voltage is outputted without being damped. The antenna element is formed by burying a helical coil coaxially into a flexible insulating resin pipe. The pitch of the helical coil is not shifted even when it is bent repeatedly. Also, no sink mark is generated in the insulating resin pipe.
