Title: Variable speed driver
Inventor: NAKAMOTO MASAHIKO
IPC: B60L9/18
Filed: 1989-03-03
Abstract: PURPOSE:To make the outputs of both two sets of inverters connected in paral lel uniform and to prevent a circuit from damaging by detecting a difference of DC voltages of input sides of the inverters, and controlling the modulation rate of the inverters in response to the difference. CONSTITUTION:Filter capacitors 4, 5 connected in series are charged from a DC power source 1 through a filter reactor 3. Coils 81, 81 of a 3-phase induc tion motor 8 are excited with the outputs of 3-phase inverters 6, 7 connected to the capacitors 4, 5. A difference  E between DC voltages EC1 and EC2 is detected from resistors 9, 11 and voltage sensors 10, 12 connected to both ends of the capacitors 4, 5 by a detector 13, its absolute value is calculated by a calculator 14, and a changeover switch 15 is set to a state indicated by a solid line/a broken line in response to positive or negative. The modulation rate PMF1 or PMF2 of the inverters 6, 7 and the output of the switch 15 are subtracted by a subtracter 16 to generate PMF1* or PMF2*, thereby modulating the inverters 6, 7. Thus, the outputs of both the inverters are made uniform to prevent components from damaging.

Abstract: PURPOSE:To feed water at the optimum timing after discharging hot-water in accordance with the condition of weather by a method wherein a control unit, detecting a temperature difference between the water temperatures of the side of heat collector and the side of the hot-water reserving tank and the water level in the same tank to release a water feeding valve, is provided in the device. CONSTITUTION:When atmospheric temperature at night is high and TH is higher than TL by a temperature TC, a comparator 48 outputs ''H'' output and a relay 62 is conducted. Consequently, the water feeding valve 21 is conducted through the contact 621 of the relay 62 and the contact 711 of a relay unit 71 to begin with the feeding of water. When the water level (h) of the hot-water reserving tank 16 is elevated due to the feeding of water and the level (h) exceeds H2, self-holding is applied on the relay unit 70 and the contacts 701, 702 are closed. Further, when the level (h) exceeds a level H2, the relay unit 70 is held by itself and the contacts 701, 702 are closed. Further, when the level (h) exceeds H3, the relay unit 71 is held by itself, the contact 711 is opened to cut the conduction of the water feeding valve 21 and the contact 712 is closed. On the other hand, in case the atmospheric temperature at night is lower than the temperature of feed water such as in winter, the comparator 48 outputs ''L'' output and the relay 62 is not conducted.

IPC: B23Q15/00
Filed: 1989-03-03
Abstract: PURPOSE:To quickly and easily produce a working path with no manual intervention by detecting an intersecting point on an offset curve to change the offset value of only a shape element part of the area where the intersecting point is detected and thus setting the optimum offset value for production of the working path. CONSTITUTION:The offset value is imported by a generated working shape curve offset value input means 2a. An interference detecting means 4 decides whether an intersecting point exists or not on a locus generated by the offset value. If so, an offset local changing means 5 changes the offset value for only a shape element part of the area where the intersecting point is detected. Then a path generating means 6 generates a working path. As a result, the interference part of an offset curve is eliminated and the working path is generated with no manual intervention.
