摘要： PROBLEM TO BE SOLVED: To provide a controller for an elevator for a detached house capable of carrying only a large-sized cargo and a heavy cargo efficiently. SOLUTION: A delivery operation mechanism for delivering a car to other floor is provided in the controller for the home elevator. Only an operation means is enough to be operated in an elevator hall 4 or 6 to carry only the cargo to a desired floor, even when a person is not allowed to get into the car loaded with the cargo such as a thick bedquilt or a furniture. When an operator moves to the desired floor intended to carry the cargo using a stair, the cargo arrives already thereby to be able to take the cargo out quickly by the operator without waiting the arrival of the car in the floor. Operation buttons 11, 13 used in common with a call registering button for calling the car are provided as the operation means, and a delivery operation and a calling operation are allowed to be discriminated in response to the length of time used to push-operate the operation buttons 11, 13 or a delivery registering button is allowed to be juxtaposed in the vicinity of the call registering button.

摘要： PROBLEM TO BE SOLVED: To provide a control device using a one-tip microcomputer to safely control a drive device provided with a motor and a braking machine without depending on a watch dog timer. SOLUTION: In the control device to control the drive device provided with the motor and the braking machine to brake the motor using the one-tip microcomputer, a relay M to close a power supply of the motor is connected to a relay B to close the power supply of the braking machine via an output unit of an input/output register of the microcomputer 7 and a predetermined logical means so that the braking machine is not energized unless the register outputs the predetermined logical signal. For example, NOR elements 21 and 22 which are output buffers to drive coils 10 and 15B of the relays M and B are connected to terminals PA1 and PB1 of a separate register, respectively. Even when the one-tip microcomputer 7 is out of control, or the register is temporarily failed, any mistaken release of the braking machine is eliminated.

摘要： PROBLEM TO BE SOLVED: To simultaneously suppress the time and labor of using a parking card and waiting time at the time of discharging a car from mechanical parking equipment and adjusting a charge at the time of leaving by the card in a parking lot, especially in the parking lot where the mechanical parking equipment is provided together with a self traveling parking lot. SOLUTION: In this parking lot management device, when the parking card 5 in which the time of entering the parking lot and the parking number of the mechanical parking equipment 9 or 11 are recorded is put into a charge adjusting machine 23, a garage leaving command is transmitted to the mechanical parking equipment 9 or 11 and the charge is adjusted. When the parking card 5 is put into the charge adjusting machine 23, since the car is discharged to a mechanical exit 14 while adjusting the charge, the waiting time is saved. Also, for the car parked in the mechanical parking equipment 9 or 11, the trouble of adjusting the charge while being in the car at an exit charge adjusting machine 33 is eliminated and the charge is adjusted only for the car parked in the self traveling parking lot 7 at the exit charge adjusting machine 33. Thus, the entire parking lot is smoothly operated.

摘要： PURPOSE:To make uniform the loss of switching elements by employing semiconductor devices having low forward voltage drop for the second and third switching elements and semiconductor elements having high switching rate for the first and fourth switching elements. CONSTITUTION:When a series multiplex inverter 1 is subjected to V/f control, the interval where the output voltage goes zero in proportion to the output frequency decreases thus increasing the average current of outside switching elements in proportion to the output frequency although the average current of inside switching elements is substantially constant. In this regard, switching elements having low forward voltage drop are employed for the inside switching elements S2, S3 constituting each phase whereas switching elements having short turn OFF time are employed for the outside switching elements S1, S4. Consequently, the loss due to forward voltage drop of the inside switching element decreases more than the increase of loss due to forward voltage drop of the outside switching element. This constitution prevents increase of loss even it the switching frequency is increased.

摘要： PURPOSE:To perform stable torque control in the whole operation region by providing a means for controlling the primary current vector of a motor and a means for controlling the slip frequency of the motor, and performing torque control by a vector control system in a low-speed operation region and by a slip frequency control system in the high-speed operation region. CONSTITUTION:A PWM inverter 1 converts DC voltage into 3-phase AC voltage and supplies it to an induction motor 2 to run an electric rolling stock. Forward/ backward command signals and power running/braking command signals outputted from a main controller 7 are put into a control command generator 6. The control command generator 6 generates an exciting current command signal and a torque current command signal for the induction motor 2 on the basis of a filter capacitor voltage signal, a primary angular frequency command signal, the power running/braking command signals and the forward/backward command signals, and transmits them to a voltage command calculator 5, a current controller 8, and a slip angular frequency calculator 19. And the PWM inverter 1 is controlled by both slip frequency control and vector control.

摘要： PROBLEM TO BE SOLVED: To provide an adjusting method for a multi-stage parking system capable of greatly shortening an adjusting time of a limit switch. SOLUTION: In the multi-stage parking system, the number of parking stages having a plurality of parking spaces are formed in a multi-stage, pallets 11 to 13 positioned at the lowest stage can be horizontally moved, pallets 41 to 44 positioned at the highest stage can be lifted and lowered in the vertical direction and pallets 21 to 23 and 31 to 33 positioned at every stage of middle parts except the lowest stage and the highest stage can be horizontally moved as well as being lifted and lowered in the vertical direction. A manually operated driving velocity V3 of pallets used in the case of maintenance is equal or approximately equal to a low traveling velocity V2 for traveling in the case the pallets are normally called for. In the case of maintenance driving, even after the operation of the limit switch in the terminal of a traveling throw of switch, an adjustment is made such that operation for an overrun time T3 equivalent or approximately equivalent to an overrun time T2 in the case of normally traveling can be performed.
