Abstract: An instrument is provided, e.g. a forceps or a pair of pliers, capable of removing a dental restoration from a tooth without destroying the dental restoration. The distal ends of a pair of jaws of the instrument each have an inner slant portion, a first outer slant portion configured to contact the boundary between the tooth and the dental restoration, and a second outer slant portion adjacent to the first outer slant portion on a side thereof remote from the boundary. When the distal ends of the jaws are disposed perpendicularly to the axis of the tooth, the inner slant portion has an inclination angle of about 20±5 degrees with respect to a horizontal plane perpendicular to the axis of the tooth. The first outer slant portion has an inclination angle of about 35±5 degrees with respect to the horizontal plane. The second outer slant portion has an inclination angle of about 1±1 degrees with respect to the horizontal plane.

Abstract: An electro-developing recording medium has a reference zone exhibiting a substantially-constant transparency to prepare correction data for correcting image pixel signals obtained by an optical and electronic reading of a developed image of the electro-developing recording medium. The reference zone is located at a margin area of an image recording area of the electro-developing recording medium. Further, the reference zone is located adjacent to a side edge of the image recording area of the electro-developing recording medium. The electro-developing recording medium includes an electrostatic information recording medium and an electric charge keeping medium. The electric charge keeping medium has the reference zone exhibiting the substantially-constant transparency. The electric charge keeping medium is formed as a liquid crystal display, and the reference zone can be defined as an empty space from which a portion of a liquid crystal of the liquid crystal display has been eliminated.

A unitary pixel is defined at an intersection between one of data electrodes 8 and a group including a pair of the scanning electrode, one of pair of the sustaining electrodes adjacent such pair of the scanning electrodes and one of the next succeeding pair of the sustaining electrodes adjacent such pair of the scanning electrodes.

Abstract: The present invention is directed to a device and method for transferring service of a local loop from one local exchange carrier to another competing local exchange carrier. A first local exchange carrier has a first switch connected to an distribution frame, which is connected to subscribers. A second local exchange carrier sets up a second switch and an interface in proximity to the distribution frame, and “half-taps” the interface with the connection between the first switch and the distribution frame. The second local exchange carrier has control over the first switch to connect or disconnect it from the distribution network.

Abstract: Endoscopic biopsy forceps with which the tissue to be analyzed by biopsy can be severed positively to the last bit so that a specimen of the tissue can be collected with minimum occurrence of bleeding. The opposed open ends of two forceps cups are made slightly different in size so that when the two forceps cups are closed, the open end of one forceps cup rests into the open end of the other forceps cup.

Abstract: Method and apparatus for manufacturing an electron gun. A beam spot coefficient is obtained from an electrostatic lens magnification and a spherical aberration coefficient of a set resistance distribution. Then, a first process loop is executed to select another resistance distribution that provides an approximate minimum value of the beam spot coefficient. It is then determined whether the beam spot coefficient is an approximate minimum value. The first process loop is repeatedly executed until the beam spot coefficient is determined to be equal to the approximate minimum value. At this point, a second process loop is executed to confirm the minimum value of the beam spot coefficient using an aberration-independent function that is dependent upon the electrostatic lens magnification and is not dependent upon the spherical aberration coefficient.

Abstract: A ink transfer printer includes a thermal head having an array of heating elements, a film having through-holes facing the heating elements, an ink space formed between the thermal head and the film, and a mechanism which brings a recording medium in contact with the film. When the heating element generates heat, the ink is transmitted through the through-hole of the film and is transferred to the recording medium. An ink amount controller is provided in the ink space, which controls the amount of ink transmitted through the through-hole to the recording medium.

Abstract: Optical fibers used in a star-type optical coupler each have a light signal input terminal and a light signal output terminal. A light signal passes through the optical fibers in a linear displacement. According to the present invention, linear displacement of the light is transformed into a generally circular movement through a coupling ring, such that the input terminals of the optical fibers need not be grouped on the same side of the optical fibers, and likewise for the output terminals of the optical fibers. Thus, the input terminal of a first optical fiber and the output terminal of a second optical fiber can be arranged adjacent to each other, so as to form a pair. When the input terminal is thus paired with the output terminal, the star-type optical coupler can be connected to peripheral optical communications apparatuses more easily.
