HS-SCCH transmission power is controlled on a transmitting side depending on whether HS-DSCH transmission is to be executed, so as to maintain total reception power on a receiving side at a constant level. The pressure switch includes a housing formed of a resin having chemical solution resistance, a pressure sensor that detects the pressure of a fluid, a separator that is formed of a resin having chemical solution resistance and that prevents the fluid from coming into contact with the pressure sensor, and a circuit unit that outputs on and off signals based on the output of the pressure sensor. The light-emitting device has an intermediate layer 104 composed of an n-type boron-containing Group III-V compound between the light-emitting layer and the upper cladding layer. The second region includes a plurality of spaced apart struts with adjacent struts being joined. The image sensor device includes a first compressively-stressed layer formed on the back side of the substrate. The cutting die includes a base and at least one scrap cutting blade and a scrap stripper that comprises one or more fingers that project from the base at an incline and which is slanted forwardly in the direction of rotation of the cutting die for stripping cut scrap pieces of corrugated board from the blade.
