摘要:
A TV camera for endoscopes comprising an image guide fiber bundle, an imaging optical system and an image sensor, used for focusing an image formed on the end surface of the image guide fiber bundle onto the imaging surface of the image sensor by the imaging optical system, and so adapted as to adjust diameter of the circle of confusion on the optimum image plane of the imaging optical system or the position of an image formed by the imaging optical system.
摘要:
An electrically driven vehicle equipped with electric motors (1, 4) for driving or braking drive wheels (3, 6), and an electric motor controller (33) for controlling the electric motors includes: wheel speed detectors (9 to 12) for detecting the wheel speed of the drive wheels and that of idler wheels (7, 8); computing means (22 to 28, 35 to 38) for computing the slip ratio of the drive wheels based on the wheel speed of the drive wheels and that of the idler wheels; and a determiner (29) for determining that the drive wheels are slipping if the slip ratio exceeds a slip ratio determination value. If the wheel speed of the idler wheels is lower than set speeds Va2, Vb2, then the determiner (29) changes the slip ratio determination value to a value having as the same sign as, and a larger absolute value than, the values λa2, λb2 used when the wheel speed of the idler wheels is higher than the set speeds Va2, Vb2. This structure shortens acceleration time during acceleration traveling and reduces braking distance during deceleration traveling while inhibiting vibrations of the electrically driven vehicle.

There is provided an assisting table capable of horizontally holding a subject and holding an angle at which a head of a subject is supported in an inclined state, and an assisting instrument, which includes a containing portion for containing a fluid to introduce a capsule medical device into a body cavity, capable of ejecting a capsule medical device with the fluid from the containing portion by detachably attaching the capsule medical device at a distal end opening portion of the containing portion and by changing a shape of the containing portion.
摘要:
This magnetic recording medium has a substrate, a nonmagnetic granular layer formed above the substrate and a recording layer formed on the nonmagnetic granular layer. The nonmagnetic granular layer is made of CoCr alloy with an hcp or an fcc crystal structure in which a nonmagnetic material segregates virtually-columnar magnetic grains. The magnetic recording medium and the magnetic storage apparatus in which the medium is used have improved reading/writing performances.

A magnetic recording medium includes a substrate having a surface where a texture is formed along a recording direction; a first underlayer formed on the surface of the substrate and made of Cr or CrMn; a second underlayer formed on the first underlayer and made of CrMn; a third underlayer formed on the second underlayer and made of Cr—X1 alloy wherein X1 includes a material selected from the group consisting of Mo, Ti, W, V, Ta, and Nb; and a recording layer formed on the third underlayer and made of a ferromagnetic material whose main ingredient is Co; wherein content of Mn of the second underlayer is greater than content of Mn of the first underlayer if the first underlayer is made of CrMn; and a total of film thicknesses of the first underlayer and the second underlayer is in a range between 2 nm and 7 nm.
摘要:
A capsule-type medical apparatus holds a drug such that a drug release such as dissolution can be realized under the same condition as in a case where the drug is delivered to an interior of a living body by itself, and realizes confirmation on whether the drug delivered to the interior of the living body is actually released to a site in the living body or not. The capsule-type medical apparatus includes a capsule-like casing which is formed in a suitable size for insertion into the living body, a net-like drug holding unit which houses a drug in a releasable manner with respect to a site in the living body, and an imaging unit which captures an image covering the drug held in the drug holding unit and a surrounding area of the drug. The imaging unit 4 captures an image as drug-source information indicating a release condition of the drug with respect to the site in the living body.
