A coating facility including: a first base outer surface coating zone; a second base inner surface coating zone; a second base outer surface coating zone; a clear inner surface coating zone and a clear outer surface coating zone; and a baking zone in which each wet coating film are simultaneously baked and cured.

Coating facility and coating method

Disclosed is a method for producing a vehicle body, which, without removing protrusions on an electrophoretic coating, improves the coating quality. The outer surface of the vehicle body is sanded prior to a pre-treatment, where the vehicle body is degreased and washed.

Vehicle body production method

Embodiments of the invention provide a small and economical two-way communications device that has both an excellent echo-cancellation function that substantially suppresses echoes over the entire frequency range and an excellent voice-operated exchange function that provides natural switching of conversation sounds while protecting against unnatural disconnection or echoes during conversation, even when a reception signal and a transmission signal are superimposed in a single transducer.

Two-way communications device having a single transducer

A base unit and a handset comprise a wireless part, a control part, and a transmission () and reception part (), respectively. Communications are switched by either of the two ways: PTT switching and tone generation in the base unit, and tone detection in the handset or PTT switching in the base unit, and voice detection in the handset. It is preferable that the transmission () and reception () part of the handset includes a single transducer type headphone. It is also preferable that photo-coupler () and a photo-switch () are provided at connection point of signal paths between the transmission () and reception part (), the control part, and between the control part and the wireless part.
