In the surface structure of an articleaccording to the present invention, a plurality of convex portionsare so disposed on a surfaceas to have intervals relative to each other and a plurality of fine convex portionshaving a diameter d and a height h smaller than those of the concave portionare formed on the surface of at least the edge portionof the concave portion. By this, when a hand touches the surfaceof the article, the proper number of convex portionsabut on a linear objectconstituting a fingerprintof a hand's finger, to thereby allow the human being to obtain a delicate-and-soft touch feeling.

Surface structure of article

A contact detection instrument including a rod, a tip sensor portion that is attached to one end of the rod and is inserted into a living body through a hole, a speaker that, from outside the living body, inputs a sound into a hollow space that is formed in the interior of the rod and the tip sensor portion, and a microphone that, outside the living body, outputs an electrical signal that corresponds to the sound inside the hollow space, with the tip sensor portion including an elastic material that covers the hollow space.

Disclosed is a surface structure of an article () including multiple protrusions () on the surface. A height H of the protrusions () is equal to or larger than 5 &#x3bc;m, and equal to or smaller than 32 &#x3bc;m, as well as at least one of a distance P between each two neighboring protrusions () and a distance W between each neighboring two of recesses () formed between the protrusions () is larger than the height H of the protrusions ().

Provided is a technique capable of allowing a person to perceive a fine relief on an object surface clearly. 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.

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.

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.
