Abstract: A robot gravity balancer includes: a tubular housing whose both ends in the direction of a longitudinal axis are closed by end plates having through-holes; a movable member housed inside the housing so as to be movable in the direction of the longitudinal axis; a compression spring disposed between the movable member and the end plate; and an elongated rod that is capable of being passed through the through-holes of both the end plates, and that is disposed in a state of having one end detachably mounted on the movable member and the other end protruding to the outside of the housing, regardless of which of the through-holes the rod is passed through. The robot gravity balancer is disposed between a first member and a second member of a robot, the second member being provided so as to be swingable around a predetermined swing axis relative to the first member.

Abstract: A life prediction apparatus is configured to accurately predict a life of a cable wired at a joint part of a robot. The life prediction apparatus includes a fatigue-level estimation unit for estimating a fatigue level of the cable based on encoder information of an actuator which moves the joint part of the robot, and a life prediction unit for predicting the life of the cable based on a fatigue level of the cable estimated by the fatigue-level estimation unit and an allowable value of the cable.

Abstract: An electronic circuit having a circuit board, a shield frame and a shield cover is provided. The shield frame is provided on the circuit board along a fringe of an area of the circuit board. The shield frame is discontinuous at a portion on the fringe. The shield cover is fastened to the shield frame so as to cover the area having the fringe along which the shield frame is provided.

Abstract: A mobile communication device configured to be connected to a first external cable is provided. The mobile communication device has a connector configured to be connected to the first external cable, and has an interface and a controller. The interface has a first sensing port, and a first circuit connected to the connector and to the first sensing port. The first circuit is configured such that the first sensing port is provided with a voltage level that changes depending on whether the connector is open or connected to the first external cable. The controller is connected to the first sensing port. The controller is configured to perform an interruption process so as to perceive the connection of the first external cable upon sensing a change of the voltage level at the first sensing port.

Abstract: Each of multipliers (1, 2) is used to respectively multiply reception data by a first cycle code generated in a first cycle code generator (3) and by an inverted first cycle code obtained by inverting the first cycle code in a polarity judging section (4). An output from each of the multipliers (1, 2) is supplied to 16 selectors (5) associated with 16 types of Hadamard Sequence patterns. To the selectors (5) are respectively fed selection signals of 16 patterns determined by figuring out exclusive ORs from a code obtained by converting each chip in a second cycle code from “1” to “0” and “−1” to “1” with respect to each of 16 types of the Hadamard Sequence patterns. The selectors (5) select and output each of the multipliers (1, 2) based on the selection signals so that outputs are accumulated in accumulators (7).
