The semiconductor device includes a device isolation structure, a surrounded channel structure, and a gate electrode. A pair of valve plate units are disposed at both ends of the cylinder body, and have refrigerant discharge holes formed therein. The first case is formed by using a molding die that has a gate for injecting resin approximately in parallel with a seal correspondence surface for forming the seal surface of the first case. The power consumption of the SCS configuration presently andor previously exercised is displayed for the clinician. The devices then establish a wireless networking communication or networking link, via their wireless network transceivers, based on the network configuration data exchanged therebetween.
