摘要： PURPOSE: To sense oxygen concentration over a wide region with immediate response. CONSTITUTION: Sensing radio waves of approximately 5mm wavelength having the nature of being absorbed by oxygen and reference radio waves separate from the wavelength of the sensing waves and having wavelength not observed by gas except oxygen are emitted from a transmission antenna 3, they are propagated in a space 1 to be sensed and received by a reception antenna 3, and oxygen concentration in the space to be sensed is sensed by a difference in received wave strength levels of the sensing radio waves and the reference radio waves.

摘要： PURPOSE:To save energy by heating warm water which circulates within a heat fence, by means of a system consuming no fuel. CONSTITUTION:The cycle of a heat pump is driven with a compressor 16 driven by means of a thermal turbine 12, so that warm water circulating within a heat fence 2 is thereby heated by the cycle of the heat pump. This constitution is most favorable from the stand point of energy saving with no exhaust gas discharged either because no fuel is used at all.

摘要： PURPOSE:To inspect whether a gas circuit breaker is leaked or not by emitting a sound wave from a sound wave emitter under the gas circuit breaking state and receiving the sound wave by a sound wave receiver at another side. CONSTITUTION:The sound wave emitter 3 and the sound wave receiver 4 are provided at one side and another side of an upstream side (a) or a downstream side (b) of a gas flow path 2 respectively across a gas circuit breaking part of the gas circuit breaker 1 such as gas emergency trip valve. After setting the breaker 1 to the gas circuit breaking state, the sound wave is emitted from the emitter 3, and the presence and absence of the leakage of the gas circuit breaking part is inspected by presence and absence of the received sound wave in the receiver 4. In this way, 200cc/min and 3,000cc/min leakage quantities can be detected in case 500Hz-4kHz and 40kHz sound wave frequencies respectively. Consequently, the leakage can be inspected easily by very simple machine and in a short time.

摘要： PROBLEM TO BE SOLVED: To easily perform, in a short time, measuring work of the three- dimensional form of an object to be measured. SOLUTION: In a light source means 10, a plurality of stripe pattern. projection lights different in phase are generated, by making lights different in wavelength pass a plurality of intensity-modulated stripe patterns different in phase. While the positional relation of the stripe pattern projection lights is maintained, the lights are synthesized and parallel lights are formed, which are projected on an object 2 to be measured. A stripe pattern reflected image generated on the object 2 is optically or electrically decomposed every wavelength, and independent stripe patterns are obtained. On the basis of the obtained patterns, the three-dimensional form of the object 2 is measured, so that the three- dimensional form can be measured by once measuring the stripe patterns. As a result, measuring work is easily enabled in a short time.

摘要： PROBLEM TO BE SOLVED: To provide a man-machine interface system with which malfunction caused by artificial error is more decreased. SOLUTION: An operator performs the input of a real operation from a console 3 and inputs an intended operation from a voice input device 5. When the intended operation is inputted from the voice input device 5, correspondent operation contents are extracted from an operation content data base 7, and a confirmation part 9 collates the contents of the real operation inputted from the console 3 with the operation contents extracted from the operation content data base 7. When the collation shows coincidence, the operation of a controlled system is executed. When the collation shows noncoincidence, a message or the like for calling the confirmation of the operator is displayed on a display device 11.

摘要： PURPOSE: To sensitively detect significant fluctuation in a process without being affected by noise. CONSTITUTION: The mutual correlation cofficients between secular measured data of two process values related in the causation in a process are calculated and significant fluctuation is detected by the sizes. After an FFT processing is performed for the secular measured data of the two process values related in the causation in the process and the data is converted into frequency axis data, the mutual correlation coefficients between each converted value are calculated and significant fluctuation is detected by the sizes. Thus, whether the fluctuation of the secular measured data of the process value including noise is the significant fluctuation of the process or the noise of an instrument, etc., or not is discriminated and only the sensitive fluctuation can be detected. Also the process having a time-lag can be flexibly coped with.

摘要： PURPOSE:To provide a dynamo which is easily adaptable to the high revolution speed of a rotary drive source, such as turbine, water wheel, and the frequency of supply power by a dynamo. CONSTITUTION:A drive shaft 2 is coaxially installed within a cylindrical conductor 1 and at the same time a field coil 7 provided in the direction of the length of the cylindrical conductor 1 is installed outside the drive shaft 2, and the field coil 7 is connected to an exciting current source 9 and at the same time the part of the cylindrical conductor 1 between both ends and the center part is made up into a power output part 11. Thereby, a loss is reduced since a mechanical decelerating means is not used to be able to reduce the size of a device as a whole. Also, the maintenance and the control are easy and the stabilization of the output frequency is very easy since the number of movable parts is small.
