The fuel cell disclosed in the present specification is provided with an electrolyte membrane comprising a three-dimensional structure composed of bridged chains of a first polymer stable to water, and a second polymer having a function as an electrolyte. In such an electrolyte membrane, the bridged chains of the first polymer hold the second polymer, and hence the membrane does not swell with wat...

The set comprises a first and a second anchoring element (1, 18) of modular type usable either as an alternative to or in combination with one another in relation to the requirements of height adjustment of a clamping fixture's components. Each of them comprises a hollow external casing (4, 19) provided with a hollow threaded screw (2, 21) for its fastening to an underlying anchoring element or to...

A ratcheting and threaded connector for connecting an upper and lower tubular member which allows an upper member to be connected to a lower member with a ratcheting action and on subsequent rotation causes a threaded spring to move into position to engage shoulders on both the upper and lower members to place them in a rigid and tight relationship. Multiple load bearing shoulders on each of the m...

A microwave oven has only a microwave sensor or both microwave sensor and temperature sensor. The microwave sensor has a wave absorber to generate heat through absorption of microwave energy and a thermistor to detect temperature of this wave absorber. The temperature sensor has a thermistor to detect the ambient temperature around the wave absorber. A controller determines a value of microwave po...
