摘要:
A highly directional microphone includes an acoustic tube and a microphone unit that is disposed inside the base end of the acoustic tube. The acoustic tube is composed of an elastic material. An adjustable member elongates and contracts the distance between the microphone unit and the front end of the acoustic tube. The acoustic tube is held by an acoustic-tube protector having openings on a peripheral wall thereof. The base end of the acoustic tube is integrated to the acoustic-tube protector, and the front end of the acoustic tube is connected to a sliding cylinder that is slidably fitted in the axis direction of the acoustic tube along the acoustic-tube protector.

A transmission-side robot control device (21) and a receiving-side robot control device (21) each include an EPROM (27) which stores a software update program and robot motion control software, a RAM (24) which stores the software update program read from the first storage section (27), and storage media (26B) which stores update software. An external terminal or a host computer for software update is not needed, and a plurality of robot control devices can be standardized to have even an old version. It is not necessary to check a version currently stored, and the update can be performed at high speed.

Processing relating to maintenance of a monitoring subject device is performed by detecting by a computer an IP address of an electronic device connected to a LAN, automatically referring to communication protocol specification data indicating a communication protocol with the electronic device indicated in remote maintenance management data provided in advance or obtained from the electronic device, and performing a communication with the electronic device by using said communication protocol and the IP address indicated by the communication protocol specification data.
摘要:
A reaction tube of a reaction apparatus includes a circular cylindrical inner tube and an intermediate tube disposed concentrically with the inner tube. A catalyst used in reforming reactions is charged in the gap between the inner and the intermediate tubes. The inner tube accommodates filler particles and is provided with a hollow member disposed therein in contact with the filler particles and capable of absorbing stress resulting from thermal expansion of the filler particles. By virtue of the provision of the hollow member which absorbs thermal stress of the filler particles that are caused to undergo thermal expansion by a high-temperature gas, such as a combustion gas, flowing through the inside of the inner tube, the apparatus is capable of preventing any deformation or breakage of the inner tube.
