摘要： A dental attachment is embedded in a denture base so as to attach to a keeper made of a soft magnetic material built in a tooth root by magnetic attractive force. The dental attachment comprises an attachment main body which has a magnetic body delivering magnetic attractive force and a cap which covers a head portion located on the opposite side of an attractive surface to attach the keeper of the attachment main body. The cap, made of a non-magnetic material, is installed in the attachment main body so as to be able to move between a contacting position (A) which contacts with the head portion and an extended position (B) which is far from the head portion for a certain distance.

摘要： A semiconductor device is manufactured using a SiC substrate. On a semiconductor region a region formed of SiC having an (11-20) face orientation is formed. A gate insulation layer is a gate oxidation layer. The surface of the semiconductor region is cleaned, and the gate insulation layer is formed in an atmosphere containing hydrogen or water vapor. After the gate insulation layer has been formed, the substrate is heat-treated in an atmosphere containing hydrogen or water vapor. This reduces the interface-trap density at the interface between the gate oxidation layer and the semiconductor region.

摘要： An MIS transistor that uses a silicon carbide substrate has a buried channel structure. The surface orientation of the silicon carbide substrate is optimized so that the device does not assume a normally on state, has good hot-carrier endurance and punch-through endurance, and high channel mobility. In particular, a P-type silicon carbide semiconductor substrate is used to form a buried channel region. To achieve high mobility, the depth at which the buried channel region is formed is optimized, and the ratio between buried channel region junction depth (Lbc) source and drain region junction depth (Xj) is made to be within 0.2 to 1.0. The device can be formed on any surface of a hexagonal or rhombohedral or a (110) surface of a cubic system silicon carbide crystal, and provides a particularly good effect when formed on the (11-20) surface.

摘要： A dental magnetic attachment having good cushioning properties against a compressing pressure which makes a denture sink appropriately on biting. The dental magnetic attachment embedded in the denture base for holding the denture in the oral cavity by a magnetic attractive force working with the magnetic assembly and a soft magnetic keeper embedded in the top of the root surface includes a magnetic assembly and a cap covering the top of the magnetic assembly. The magnetic assembly has a hollow in the center of its top. The cap with a button is placed on the magnetic assembly, inserting the button into the hollow to contact to its bottom. On biting, the button is compressed, to be deformed with a shorter thickness and at this time a sleeve formed as a body around the core slides down along the side of the magnetic assembly to reduce the thickness of the dental magnetic attachment. This sliding makes the denture sink uniformly and appropriately. The dental magnetic attachment has good cushioning properties and offers a good feeling to a patient when biting with the denture.

摘要： An information reproducing apparatus quickly retrieves tape position information of a tape-shaped recording medium on which tracks are formed so as to record information and tape position information. This apparatus includes a tape speed detecting unit for continuously detecting the running speed of the tape-shaped recording medium, a cylinder speed setting unit for setting target values of rotation of a rotary cylinder for making constant the component of speed at which the head moves in a track direction according to the output of the tape speed detecting unit, and a cylinder control circuit for controlling the rotary cylinder so as to adapt its rotation to the target value of velocity of the cylinder set by the cylinder speed setting unit. By rotating the cylinder at a rotational speed at which data reproduction can take place at a tape speed obtained by the tape speed detecting unit, the tape position information can be positively read out even in a transient state when the running speed of the recording medium changes.
