A liquid droplet ejection head has a liquid introduction part, a pump part which is in communication with the liquid introduction part, and a nozzle forming plate in which a nozzle port is formed in an overlapped manner with the pump part. The method comprises deforming the skin so that a region of skin protrudes from surrounding skin, and applying radio frequency energy to the skin. The communication control device includes a Web information storing unit configured to store the Web information, and a Web information returning unit configured to retrieve the Web information corresponding to the language identifier from the Web information storing unit and to send the retrieved Web information to the information processing apparatus. In addition, a getter chamber is formed in the same surface of the second substrate as the pressure-measuring chamber, and the getter chamber is connected to the vacuum chamber. The shocking action is caused by the expansion and contraction of the heater tubes resulting from the colder water charge flowing through the heater tubes which is then followed by the hotter process fluid flowing through the heater tubes. Said machine also comprises a fat analysing device for determining the fat content in said meat.
