A calculating device 10 for calculating the concentration of elements contained in a sample 13 based on the FP method is provided. The calculating device 10 is operable to assume a concentration of unmeasured elements as far as unmeasured elements, of which fluorescent X-rays are not measured, are concerned, and, also, to utilize, in place of the secondary X-rays emanating from the unmeasured elements contained in the sample, scattered X-rays of the primary X-rays at least equal in number to the number of the unmeasured elements, of which concentrations are assumed, and including scattered X-rays of different wavelengths before they are scattered from the sample.

An industrial robot includes a movable arm and an electric motor driving the arm. A current flowing through the motor is controlled so that the arm is moved into predetermined positions and is balanced in the predetermined positions sequentially. A device memorizes values of the motor current at which the arm is balanced in the respective predetermined positions. A target value of the motor current is calculated on the basis of the memorized motor current values. The target motor current value allows the arm to be balanced in a given position.

The joint units, driving units and arms each have connecting surfaces thereon having positioning parts and setting-fixing parts in a predetermined pattern for enabling the joint units, driving units and arms to be detachably connected to other joint units, driving units and arms at corresponding connecting surfaces to form arm units with the desired joint units, driving units and arms. The joint units each have a stationary frame and a follower frame rotatably connected to each other and driving power transmitting mechanism connected between said frames and including reduction gears. The driving units each have a motor and an output member fixed to the motor shaft which, when a driving unit is connected with a joint unit, is engaged with power transmitting mechanism.

It is an object of the present invention to provide an opening/closing hinge device which can be produced simple in construction and inexpensive in production by reducing the number of the parts forming part of the mobile device and to provide a mobile device small in size, reduced in cost and sufficiently reliable in the hinged members. The second member is rotated with respect to the first member toward the opening operation direction through the movable cam (150) by the urging force of the urging means (170) when the operation cam (130) is displaced in the predetermined operation direction by the external operation force. The fixed guide member (110) has inclined guide portions (115) each inclined at an advance angle in a predetermined inclination direction with respect to the surface perpendicular to the guide center axis to have the second rotation cam (140) rotated around the guide center axis in response to the displacement of the second rotation cam (140) along the guide center axis. The second rotation cam (140) being driven to rotate by the inclined guide portions (115) under a pressing force from the movable cam (150) to have its engagement state with the movable cam (150) changed and to have the urging direction of the second member by the urging means (170) changed when the operation cam (130) is operated to cause the first rotation cam (160) to be rotated from the operation starting position.

摘要:
A disk recording/reproducing device includes a power transmitting mechanism which transmits movement of a pickup while engaging with the pickup, and a disk retaining mechanism which, in response to the movement of the pickup transmitted by the power transmitting mechanism, retains a disk on a turntable or releases retention of the disk. Radially inward movement of the pickup causes the disk retaining mechanism to retain the disk on the turntable, while radially outward movement of the pickup causes the disk retaining mechanism to release retention of the disk. For accomplishing the release of the retention of the disk upon the radially outward movement of the pickup, an operation switching mechanism is provided for changing a position of the power transmitting mechanism to cause the power transmitting mechanism to engage with the pickup upon the radially outward movement of the pickup.
摘要:
In an industrial robot including a control apparatus capable of executing control of the robot in a position control mode, a velocity control mode and a current control mode. The control apparatus includes a changeover section (20) for executing changeover between the position control mode and the current control mode. The position of an object is sensed by driving a set of arms of the robot in a force control mode which is a combination of the velocity control mode and the current control mode, and detecting the position at which the arms contact an object and are halted. Detection of the halted condition is performed based on a condition of an output signal produced from a position sensor (13), and by repetitively performing such detection for a plurality of different points on the body surface, a plurality of position values are derived which are compared with reference position data. Any change of the position of the object from a reference position is thereby computed by a computation section (24), whereby the robot itself is capable of sensing the position or attitude of an object, in 2 dimensions or 3 dimensions.

A method for forming an electrode of a solar battery on an electrode forming face of a semiconductor substrate, comprises: applying a resin containing a conductor material to be the electrode onto an electrode forming region of the electrode forming face; causing a pattern transfer member, on which a reverse pattern obtained by reversing a pattern of the electrode is formed, to face the electrode forming face, and registering the pattern transfer member on a position in which the electrode is to be formed in the electrode forming face; pressing the pattern transfer member against the electrode forming face to transfer the electrode pattern to the resin containing the conductor material; separating the pattern transfer member from the resin containing the conductor material; and baking the electrode pattern transferred to the resin containing the conductor material to form the electrode on the electrode forming face of the substrate.
