摘要： PROBLEM TO BE SOLVED: To solve such a problem that, in a conventional energy saving service, a user and an energy saving service provider cannot necessarily receive merits of energy saving because initial investment by a contractor (for example, the user of an electric power facility) is necessary and the energy saving service provider guarantees a target value of energy saving to the user.SOLUTION: For a facility which is owned by a user who desires energy saving and has the target load facility, present power consumption is measured. A service provider installs an inverter, or an inverter and a motor or the like in the target load facility, performs motor speed control by the inverter, obtains merit charge based on difference between the present power consumption and power consumption with use of the inverter, and distributes the merit charge by reflecting the merit charge to content previously decided between the user and the service provider.

摘要： PROBLEM TO BE SOLVED: To provide a permanent magnet type dynamo-electric machine capable of attaining stable driving even when the dynamo-electric machine using a concentrated winding stator and a magnet imbedded type rotor is driven by a position sensorless 120° excitation inverter.
SOLUTION: This permanent magnet type dynamo-electric machine has the stator 6 around which a concentrated winding type armature winding 5 is wound so as to surround the plurality of teeth 3 formed at a stator core 2, and the rotor 7 in which the permanent magnet 10 is accommodated in a plurality of permanent magnet insertion holes 9 formed at a rotor core 8. The permanent magnet 10 is formed into a protruding V shape relative to a shaft of the rotor 7, a roughly V-shaped recess portion 13 is formed between poles at an outer periphery surface of the rotor core 8, an angle which is formed by both intersections between the rotor outer periphery surface and the roughly V-shaped recess portion relative to the rotor shaft is taken as θ2, and θ2/θ4 becomes ≥66.7% or ≤85.7% when the value of 360°/the number of poles is taken as θ4. Torque by magnet flux is increased, and armature reaction flux generated by the armature current is deceased, therefore, abscissa inductance is decreased, thus promptly commutating the armature current.

摘要： PROBLEM TO BE SOLVED: To provide a permanent magnet dynamo-electric machine where vibration or noise is not increased with increase in armature current. SOLUTION: A permanent-magnet dynamo-electric machine is provided with a stator with armature winding installed in a plurality of slots formed in its stator core and a rotor with a permanent magnet held in a plurality of permanent magnet insertion holes formed in its rotor core. In the electric rotating machine, the permanent magnets are so formed that they are substantially in an arc shape, protruded toward the outside radius of the rotor core and further substantially in an arc shape, protruded toward the inside radius of the rotor core. As a result, the torque resulting from magnet magnetic flux is increased and further the armature reaction magnetic flux produced by armature currents is reduced. Thus the permanent-magnet electric rotating machine allows vibration and noise to be reduced, without having to reduce the torque generated by the dynamo-electric machine.

摘要： PROBLEM TO BE SOLVED: To prevent abnormal temperature rising caused by failure of a cooling device or contact failure of a power source connection part by measuring the temperature with a non-contact type temperature measuring means, and comparing the measured temperature with a reference temperature to detect temperature abnormality. SOLUTION: Thermal radiation energy from a metal part at both ends of a Xe lamp is converted into a temperature signal with a temperature detecting part 12, and the temperature signal is sent to a comparing part 14 through an amplifying part 13. The comparing part 14 compares the measured temperature signal with a signal from a reference temperature signal part 15, and if the measured temperature is higher than a reference temperature, a signal of an abnormal temperature rising display is sent to a display part 16. At the same time, a lamp extinguishing signal is sent to a lamp power source control part 17 to control a lamp power source 18 and to put out lights. The temperature detecting part 12 converts thermal radiation energy into an electric signal with a silicon photocell through a protection filter, a condenser lens, a light quantity adjusting plate, and a spectral sensitivity adjusting filter, and directly measures the temperature of the metal part at both ends of the lamp 11.
