PROBLEM TO BE SOLVED: To provide a wheeled inverted pendulum mobile unit capable of stopping itself without shaking its body. SOLUTION: A mobile unit 100 includes support legs 20 downwardly extending from a body 10 and grounded at the front and behind of an axle 14 of driving wheels, with lower ends going up and down according to the inclination of the body 10, and a lock mechanism 26 fixing the position of the lower ends of the support members. The support legs 20 are grounded regardless of the operation/non-operation of an inverted pendulum control and move up and down according to the inclination of the body 10. Therefore, the support legs 20 do not interfere the inverted pendulum control though being grounded always. In the case of stopping the inverted pendulum control, the positions of the lower ends of the support legs 20 are fixed by operating the lock mechanism 26. When the inverted pendulum control shifts its state from operative to inoperative, the support legs 20 can support the body 10 without time lag. Thus, the body is not shaken by having the telescopic support legs 20 which is always grounded and the lock mechanism 26. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a traveling type moving body capable of sufficiently eliminating dirt from its wheel, and its control method. SOLUTION: The traveling type moving body has the wheel 2 which advances in a first direction when rotating normally and advances in a second direction when rotating reversely and a brush 3 disposed in the vicinity of the wheel 2. The traveling type moving body also has a control section 5 which brings the brush 3 into contact with the wheel 2 on the side of the second direction of the wheel 2 during its normal rotation and keeps the brush 3 away from the wheel 2 during its reverse rotation.

PROBLEM TO BE SOLVED: To provide a neuronal apparatus and the like suitable for performing appropriate control by making a neuron threshold variable, extending Hebb's rule, and devising integer expressions, in a neuronal network. SOLUTION: In the neuronal apparatus 101 for simulating nerve cells, a threshold storage part 102 stores a threshold variable θ and two threshold coefficients Δθ1 and Δθ2, an input reception part 103 receives one or more input of input signal values at prescribed time intervals, an output part 104 outputs as an output signal value 1 assuming that the neural apparatus 101 is igniting when a total sum s of input signal values is threshold variable θ or larger and 0 assuming that the neural apparatus 101 is at rest otherwise; and a threshold update part 105 calculates Δθ1X + Δθ2(X-1) from an outputted output signal value X and the stored threshold coefficients Δθ1 and Δθ2 and updates the value of the threshold variable θ to be stored by the threshold storage part so that it increases just by the result of calculation.

Abstract:
PROBLEM TO BE SOLVED: To provide a technology for generating steam having a stable steam quality and an excellent response to load changes. SOLUTION: In a first steam generator, flow rates Y1 and Y2 of combustion fuel supplied to a vapor phase of a heat exchanger are feedback-controlled based on steam temperature Tm, while the flow rate Y3 of combustion fuel supplied to a liquid phase is feedback-controlled based on steam flow rate Fm. The two types of feedback controls are carried out independently from each other. A second steam generator is controlled based on the steam temperature Tm, calculated as a weighted average of a plurality of local steam temperatures measured at points near the outlets of a plurality of small channels wherein the steam flows.
