    • There is a need for high-precision detection timing in a radiological imaging apparatus using a semiconductor detector so as to decrease time variations against a noise and easily correct process variations. A radiation detection circuit includes: a semiconductor detector; charge accumulation means connected to the semiconductor detector; a circuit to discriminate timing of a signal generated from the charge accumulation means based on a specified threshold value; a shaper 1 to limit a band from the charge accumulation means using a first time constant; a shaper 2 to limit a band from the charge accumulation means using a second time constant; a circuit 1 to hold an analog peak value 1 for the shaper 1; and a circuit 2 to hold an analog peak value 2 for the shaper 2. The radiation detection circuit performs a signal process to generate timing correction data based on the analog peak values 1 and 2 and correct timing data from the timing discriminator circuit.

    • An allowable ranges of a horizontal component of the translation floor reaction or a floor-surface-parallel component of the translation floor reaction force of a legged mobile robot 1 or a horizontal component of a total center-of-gravity acceleration or a floor-surface-parallel component of a total center-of-gravity acceleration of the robot 1 (hereinafter referred to as a friction force component) is set, and a provisional movement of the robot 1 is determined so as to satisfy a predetermined dynamical equilibrium condition. When the friction force component determined by this provisional movement departs from the allowable range, a rate of change of an angular momentum around the center of gravity of the robot 1 is changed from the provisional movement so as to satisfy the dynamical equilibrium condition while limiting the friction force component within the allowable range to thereby determine a movement of a desired gait. Consequently, not only walking of the robot 1 but also running thereof can be performed properly, and a gait that does not cause slippage is generated.

    • When gait parameters for specifying a gait to be generated of a mobile robot (1) are determined, the values of the priority parameters of the gait parameters are updated from the values of the priority gait parameters of predetermined base gait parameters such that the priority parameters approach and reach the original required values step by step. For every update, out of non-priority parameters other than the priority ones, the parameters to be sought are determined by seeking so that the parameters may satisfy the gait boundary condition on the dynamic model of the robot (1). Thus, the new gait parameters including the determined parameters and the updated priority parameters are determined. Lastly, the gate of the mobile robot (1) is generated using dynamic model and the new gait parameters determined when the priority parameters are made to agree with the requested value.
