摘要： PROBLEM TO BE SOLVED: To provide a cleaning machine without giving bad effects on the cleaning machine by lowering the alkaline degree of alkaline cleaning water. SOLUTION: In a waste water process, an electrode 25 in a waste water tank 23 is set to be a positive electrode, and an electrode 24 in an assistant tank 22 is set to be a negative electrode. Alkaline cleaning water is charged into the waste water tank 23 by action of a water feed pump 36, and electrodialysis is performed by action of a DC power source circuit 39. In the waste water tank 23, sodium ions in sodium hydroxide solution as alkaline cleaning water pass through an ion exchange film to get into the assistant tank 22 by electrodialysis. The sodium ions are thus recovered into the assistant tank 22. Hydroxyl groups (OH ) are replaced by oxygen gas to be discharged by electrodialysis, and hydroxyl groups in alkaline cleaning water are reduced to lower the alkaline degree.

摘要： PROBLEM TO BE SOLVED: To provide a steam generator which is small-sized and susceptible of less failure. SOLUTION: An upper cover 3 and a lower cover 4 are mounted to a top and bottom of a cylindrical-shaped insulating casing 1. Provided in the casing 1 is an electrically conductive heating element 9 having therein a multiplicity of voids and adapted to generate heat by induction heating when an AC current passes through a coil 2 wound around an outer peripheral wall of the casing 1. Water supplied into the casing 1 through a feed water pipe 8 is heated by contact with the heating element 9 to make water vapor to be transferred outside the easing 1 through a delivery pipe 7. The heating element 9 is hollow at its core portion to allow a water level detecting electrode bar 5 to be inserted thereinto from the upper cover 3. With such arrangement, a highly reliable steam generator free of troubles such as plugging of a water pipe, disconnection of an electric heater and the like can be obtained which can provide water vapor efficiently with a compact configuration.

摘要： PURPOSE:To follow up to the maximum electric power point of the solar battery at a high speed by varying the quantity of variation in reference operation point to a small value in an area nearby the maximum electric power point when the reference operation point of the solar battery is varied to reach the maximum electric power point. CONSTITUTION:The voltage V of a DC power source 1 follows up a reference operation voltage Vref and DC output electric power PDC is generated; and an inverter 2 converts it into AC output electric power PAC. A controller 5 is a function generator which generates a reference operation voltage Vref(t) at time (t) as (equation 1) by using outputs at time t-T and time t-2T (t: sampling cycle). A gain K is plus when a detected value P*AC of the AC output is increasing or minus when decreasing. The gain K is made small nearby the maximum electric power point and then the quantity of variation in the reference operation voltage Vref(t) is varied to the small value in the area nearby the maximum electric power point, thereby following up to the maximum electric power point of the solar battery at a high speed.

摘要： PURPOSE:To reduce vibration and noise by controlling individual speeds of zones by rotating angle detection signal obtained electrically and independent controllers provided for zones of electric angles partitioned by the rotating angle detection signal. CONSTITUTION:One set of input changeover switch 4a and output changeover switch 4b of a controller 4 is selected from the input changeover switches 4a and the output changeover switches 4b of the controllers 4 provided in number corresponding to the number of zones partitioned by the outputs of position detectors 1 by the output of the position detector 1, a deviation between the output of a speed detector 2 and a speed command value signal 3 is calculated, and a compressor 7 is driven through a PWM generator 5 and an inverter 6. As a result, a torque responsive to torque change due to a load for each zone divided from one revolution of a motor 7 can be generated. Thus, a speed variation during one revolution is suppressed, and vibration and noise are reduced.

摘要： PURPOSE:To stabilize the commercial power system, by maintaining the output power from an inverter for inverting DC current fed from solar cells or batteries into AC power at a constant level with respect to time and setting the output power higher than the maximum output power from the solar cells. CONSTITUTION:An inverter 3 follows to a command output fed from a controller 6 and feeds effective power to a commercial power system 4. Output power from the inverter 3 is maintained constant with respect to time and set higher than the maximum output from solar cells 1. Batteries 2 discharge power to the inverter 3 and the power stored in the batteries 2 reduces because of day time discharge. The reduction is supplemented through recharge of the batteries 2 with midnight power.

摘要： PURPOSE:To effectively use power, by controlling the voltage at both ends of an electrolytic capacitor to be made equal to reference voltage higher than the peak voltage of a commercial power. CONSTITUTION:The output direct current of a solar battery 1 is fed to an electrolytic capacitor 3 via a diode 2, and is fed to an inverter 4 with ripple removed. By the inverter 4, direct current is converted to alternating current, and is connected to a commercial power system 7 via an AC switch 5 in a closed state, and is fed to a load 6. Then, voltage at both ends of the electrolytic capacitor 3 is detected by a DC voltage detector 8, and detection voltage due to the detector 8 and reference voltage higher than the peak voltage of the system 7 due to a reference power source 11 are compared with each other by a controlling means 16, and the output of the inverter 4 is controlled by the controlling means 16. As a result, even if the inverter 4 is set in a stopped state, current is not to flow to the capacitor 3 from the system 7.
