The present disclosure provides a fixed point stabilization device for a legged mobile body having a generating mechanism for generating a fixed point. The present disclosure also provides a fixed point stabilization device for a legged mobile body comprising a stabilizing device for stabilizing the fixed point in accordance with a leg grounding position of the legged mobile body. The fixed point is generated by inputting a predetermined constant torque to a joint of a leg of the legged mobile body on the basis of the energy balance in the legged mobile body, leg switching, and a leg swinging motion. The fixed point is stabilized globally by keeping the leg grounding position of the legged mobile body constant using a stopper.

A measurement device can detect a degree of bending of a linear body with a sensor when compressive force in a direction of longitudinal axis is applied to the linear body as a result of contact of a tip end of the linear body with an obstacle. Then, the detected degree of bending of the linear body is converted to compressive force in the direction of longitudinal axis applied to the linear body based on predetermined correlation between the degree of bending and the compressive force, so that presence of an obstacle in a direction of travel of the linear body can be sensed based on increase in the compressive force. In addition, as the same measurement device is applicable to linear bodies of various shapes and materials, cost effectiveness is achieved.

A garbage disposing device of an energy-saving type comprises a housing having an air intake port and an air discharge port, and a vessel mounted within the housing to store therein food wastes. The vessel has an air inlet and an air outlet. An intake passage is formed in the housing to extend from the intake port to the air inlet for introducing a fresh air into the vessel. An exhaust passage is formed within the housing to extend from the air outlet to the discharge port for discharging therethrough an air containing unpleasant odor resulting from a decomposition of the food wastes. A deodorizer unit comprises a catalyst for decomposing the unpleasant odor in the air, a heater for activating the catalyst, and a case for incorporating therein the catalyst and the heater. In the present invention, the deodorizer unit is mounted in the exhaust passage such that an outer surface of the case is exposed in the intake passage, and the fresh air in the intake passage is warmed by a contact with the outer surface of the case inevitably heated by the heater to enhance the decomposition of the food wastes. This brings an energy conservation by application of a waste heat given off from the case of the deodorizing unit.

A linear body drive device capable of safely and reliably operating a linear body is provided. A linear body insertion device includes a drive portion, an operation portion, a sensor portion and a processing portion serving as a measurement portion, and an output portion serving as a notification portion. The drive portion drives a linear body having flexibility. The operation portion includes an input member (an operation lever) operated by an operator for controlling performance of the drive portion. The sensor portion included in the measurement portion detects compressive force in a direction of longitudinal axis applied to the linear body, based on a degree of bending of the linear body driven by the drive portion. The output portion provides notification of data of compressive force detected by the measurement portion.

A tactile device of a tactile display slides above an object. The tactile device comprises three rods which are free to move up and down. Lower ends of the rods are in contact with a surface of the object. Upper ends of respective rods touch a palmar-side skin equivalent to positions of three joints of a first finger or a second finger. When the tactile device is slid, upper ends of respective rods move up and down in accordance with a surface relief of the object. In response to the movement of the tactile device, the three rods push three finger joint positions of the palmar-side skin with a stroke equal to a height of the relief.
