摘要： An actuator, which allows a controller to be commonly applied to a plurality of models without requiring complicated setting operation of control parameters, and is superior in cost effectiveness, reusability and expandability, is provided. And further, a motor unit and a controller unit constituting the actuator are provided. The motor unit is equipped with a motor, a motor drive circuit and a parameter memory, which stores characteristic parameters necessary for controlling the motor. A controller unit, which is adapted so as to be detachable to the motor unit, is provided with a motor control circuit and a communication control circuit. When the controller unit is attached to the motor unit, characteristic parameters stored in the parameter memory are loaded via a communication connector, and used for setting control parameters for the motor control circuit.

摘要： A member is disclosed which includes a hard carbon film provided through an interlayer or directly on a main body such as a vane. A mixed layer is formed within the main body or interlayer adjacent to an outer surface of the main body or interlayer. The mixed layer contains carbon and a constituent element of either the main body or the interlayer. The mixed layer has a carbon content gradient in its thickness direction so that a carbon content in a thickness portion thereof closer to an outer surface of the mixed layer is higher than in a thickness portion thereof remoter from the outer surface of the mixed layer.

摘要： In a linear compressor driving apparatus, a position instructing portion (31) outputs a position instruction value Pref of a piston in accordance with an equation A*sin .omega.t. A position control portion (33) calculates a speed instruction value Vref by multiplying difference between position instruction value Pref and position present value Pnow by a constant Gv. A speed control portion (35) calculates a current instruction value Iref by multiplying a difference between speed instruction value Vref and speed present value Vnow by a constant Gi. A current control portion (37) controls a power source (3) so that current present value Inow becomes equal to the current instruction value Iref. Phase control portion (38) adjusts .omega. and Gi so as to eliminate phase difference between speed present value Vnow and current instruction value Iref. Since thrust of linear motor can be directly and appropriately controlled in accordance with the load condition, high efficiency is obtained.
摘要翻译：在线性压缩机驱动装置中，位置指示部（31）根据等式A *sinωt输出活塞的位置指示值Pref。位置控制部分33通过将位置指令值Pref和位置存在值Pnow之间的差乘以常数Gv来计算速度指令值Vref。速度控制部分35通过将速度指令值Vref与速度当前值Vnow之间的差乘以常数Gi来计算当前指令值Iref。电流控制部分（37）控制电源（3），使得当前的当前值Inow变得等于当前指令值Iref。相位控制部分（38）调整ω和Gi，以消除速度当前值Vnow和当前指令值Iref之间的相位差。由于线性电动机的推力可以根据负载条件直接适当地控制，因此可以获得高效率。

摘要： A bogie is provided with a wheel mechanism that can move each wheel in a vertical direction, and a control unit to perform impedance control of moving force to be applied to a wheel supporting unit in which a motor provided in the wheel mechanism is supporting the wheel. When the third wheel is to climb up a step, the control unit controls output of each wheel mechanism to cause the third wheel to make contact with a wall face of the step, and facilitate the wheel to move upward so that it can climb up the step, and the other wheels can be immediately made to contact with the ground even when the climbing wheel irregularly moves in a vertical direction, so that the bogie remains in a stable posture.

摘要： A linear compressor according to the invention is for generating compressed gas and includes two pairs of pistons 608a, 608b and cylinders 607a and 607b coaxially provided and facing opposite to each other, a shaft 603 having pistons 608a and 608b at its ends, coil springs 605a and 605b coupled to shaft 603 for returning a piston departed from a neutral point to the neutral point, and a linear motor 613 for causing shaft 603 to axially move back and forth, thereby generating compressed gas alternately in two compression chambers 611a and 611b. Thus, the non-linear force of the compressed gas acting upon the pistons may be divided into two/reversed in phase. As a result, as compared to a conventional structure having only a single piston, the motor thrust may be reduced and linearized for the purpose of improving the efficiency. Furthermore, the size of the device may be reduced as well as the vibration/noises caused thereby may be reduced.

摘要： A force detection device of the present invention includes a handle to be given an operation force by an operator, disposed on a support reciprocatably in a first axis direction along a forward/backward direction of the truck and a second axis direction orthogonal thereto. A pair of force detection parts capable of detecting only a force in the first axis direction is disposed on the support in a spaced-apart relationship in the second axis direction. A force propagation body intervenes between both force detection parts and the handle. A part of the force propagation body passes through the inside of a gripped part of the handle. The force propagation body is coupled to the handle by a coupling axis extending in a third axis direction orthogonal to the first axis and second axis so as to be capable of relative rotation about the coupling axis.
