摘要： Disclosed is an apparatus for compensating mechanical loss produced in a load moving or transporting machine in which the load can be moved by a small external force as if the load were positioned in a space free from gravity or graviational influence by constantly producing a force from an electric motor which is equal to the weight of the load suspended by the apparatus. A circuit for simulating friction produced upon movement of the load is provided in a torque control circuit for the motor, wherein torque command signal for the motor is divided into a torque command signal corresponding to the weight of load and a torque command signal component corresponding to the friction produced as the load is moved and thereafter is applied to the torque control circuit for the motor.

摘要： A moving apparatus for a load has a speed control circuit and a torque control circuit, each circuit controlling a motor for lifting the load. When operation of the speed control circuit is stopped, the torque control circuit stores the value of the torque which is equal to the weight of the load and keeps the torque from the motor at a constant value in response to the weight of the load. In this way, the load can be moved as if it were located in a gravity-free state.

摘要： PROBLEM TO BE SOLVED: To improve a power converting efficiency in driving a small load, and extend the life of a battery when driving loads of different sizes. SOLUTION: When driving a normal load 11, a switch 16 is turned off and therefore an inductance is increased since both o f inductors 2, 15 are in an on state, thereby decreasing inductor current iL. By the on/off operations of a switching device 3, an operation that the power accumulated in the inductors 2, 15 is discharged to an output capacitor 9 is repeated, thereby keeping the output voltage E in a specified range. When driving a maximum load 12, the switch 16 is turned on and therefore the inductance is small since only the inductor 2 is in an on state, thereby increasing the inductor current iL and charging power by the inductor 2. Therefore, even if the load current iR becomes large because of the maximum load 12, the decrease in the output voltage E can be sufficiently compensated by the power accumulated in the inductor 2, and the output voltage E can be kept in the specified range.

摘要： PURPOSE:To provide a heat protecting device in which an operation for mounting a component such as a detector, etc., to protect against an overheat is simplified and an area for mounting an overheat protecting detector and an entire height of the component are reduced. CONSTITUTION:An overheat detector 4 is mounted on a side opposite to that of a circuit board 17 in which heat generating elements 6, 7, 8 are mounted, and connected by a conductor 18 passing both sides to detect abnormal overheats of the elements 6, 7, 8. An overheat protecting circuit stops the operations of the elements 6, 7, 8 with the signal from the detector as a trigger, thereby protecting the elements 6, 7, 8 against the overheat.

摘要： PURPOSE:To simplify a circuit and to make a switch compact by assembling the reset switch of an automatic power off circuit into the automatic power off circuit. CONSTITUTION:This information processor is composed of a power supply unit 25 to convert the power of a battery 1 to a stabilized direct current power, and a main control circuit 10 to set the processing of information, keyboard 59 and peripheral device 60. In such a case by turning an automatic power off state to a switch off state and turning a switch on state to an automatic power off cancel state, the reset switch is assembled into the automatic power off circuit and a power supply switch for power to turn on/off a power line is replaced with the reset switch for canceling automatic power off. Thus, the automatic power off circuit can be simplified and the switch can be made compact.

摘要： PURPOSE:To surely prevent the malfunction by detecting the terminal voltage of a battery for calculation of the remaining electric energy and the electric energy to be consumed for execution of a designated process mode and comparing both calculation results with each other to show the propriety of execution of the process mode. CONSTITUTION:The terminal voltage of a battery 1 is detected by a main control circuit 4 of a CPU, and the remaining electric energy is calculated via the CPU. At the same time, the set value of the current consumption is stored in the circuit 4 in response to the process mode designated via a key board 5. Based on this set current consumption value, the total electric energy of the process mode is calculated. Then both calculated results are compared with each other, and the propriety of execution of the process mode is decided based on the comparison result and shown on a display 6. Thus it is surely decided whether the process mode should be carried out or not and the malfunctions of an information processor can be prevented.
