Title: Reel turn table moving device
Inventor: UMEE KAZUNORI
IPC: G11B15/32
Filed: 1985-05-17
Abstract: PURPOSE:To make it possible that three kinds of cassette tape for which the reel position is changed linearly are set to one device, by displacing the axis of rotation of the first rotating body and the axis of turning of a turning arm held by this rotating body so that the reel turn table is arranged in three positions on a straight line when the rotating body is rotated. CONSTITUTION:When a turning arm 22 is turned with a turning shaft 23 fixed at one point in case of movement from a position X for large cassette to a position for middle cassette, the axis of rotation of a reel turn table 24 is in a position V and a position for small cassette where the arm 22 is turned furthermore and three points are not arranged on a straight line; but the axis of turning of the turning arm 22 is moved to arrange them on a straight line. In such a case, a length (l) between axes and a length S are made equal to each other. The extent of movement of the table 24 to each cassette position is determined by the length of the turning arm 22 and the turning angle. The length (l) between axes is determined by the length S generated by turning of the turning arm 22 and the rotation angle of the first rotating body 26.

Title: Manufacture of semiconductor device
Inventor: AKIBA TAKAO
IPC: H01L29/423
Filed: 1984-05-24
Abstract: PURPOSE:To reduce the source-drain concentration by a method wherein a double-layer structure of a gate oxide film and a gate electrode is prepared on a semiconductor substrate, and the gate electrode is side-etched by a factor of the duplication of the source-drain and the gate electrode by tapering the side surface of the gate electrode. CONSTITUTION:The gate oxide film 3 is formed in the part serving as a transistor on the semiconductor substrate 1, and the whole surface is coated with the gate electrode 2. After a photo resist 7 is patterned, the gate electrode 2 is patterned by inclining its side surface by anisotropic etching with the photo resist 7 as a mask. When the source-drain 5 is formed by ion-implanting an impurity using this electrode 2 as a mask, the impurity concentration of the source-drain 5 gradually decreases in the neighborhood of the electrode 2. Next, the part of duplication is removed by whole-surface etching the electrode 2 by anisotropic etching. This manner eliminates the variation in threshold voltage due to hot carriers because of a low impurity concentration in the neighborhood of the electrode 2 and can prevent the punch-through phenomenon.

The read numerical map is divided into plural areas and made polygonal and shown (step 103). The image data is overlapped on the polygonal data and is shown (step 104). Parts which have colors that are different from a background color are automatically detected as an artificial building (step 106) from image data that finishes adjustment (step 105). Three-dimensional geographical image data is created (step 107) by synthesizing texture data that is undergone texture processing and the polygonal data.

Title: Paper feeder
Inventor: WATANABE KAZUO
IPC: B65H3/06
Filed: 1990-04-21
Abstract: PURPOSE:To prevent a sheet from remaining, when a paper feed cassette is drawn out, by providing a means for temporarily reversing a feed means, and actuating the reversing means for a predetermined time after the final feed is finished. CONSTITUTION:When feed means 47 to 49 are actuated in a condition that a sheet 2 in paper feed cassettes 44 to 46 is brought into press contact, feed action in an upper layer part of the sheet tends to feed out these sheets from the paper feed cassettes 44 to 46. This fed out sheet 2, when it reaches a part where the feed means 47 to 49 and a handling pad 51 are brought into press contact, is impeded from advancing by the handling pad 51 and fed only after the uppermost layer sheet, directly receiving feed action by the feed means 47 to 49, passes through. Accordingly, the sheet can be fed sheet by sheet. Since a reversing means 64 is actuated for a predetermined time when the final feed is finished, a sheet, even when it is fed before and placed in a narrow space between the feed means 47 to 49 and the handling pad 51, can be forcedly fed back and removed from the space to a side of the paper feed cassettes 44 to 46.

Title: Sensitive inclination sensor
Inventor: MASUDA NORIO
IPC: G01C9/24
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To enable attainment of miniaturization, high sensitivity and cost reduction by a construction wherein the inside upper surface of a vessel with a liquid put inside is made a flat or recessed surface and an indent is provided almost in the center of this flat or recessed surface, while a bubble is so provided as to be in contact with the indent. SOLUTION: When the whole of a vessel 1 is inclined clockwise, a force to move a bubble 6 upward acts thereon and it is distorted leftward. When this inclination is restored to the original state, the distortion of the bubble 6 is gone and the original shape thereof is recovered. The amount of distortion of the bubble 6 increases in proportion to an angle of inclination in this way and the bubble leaves an indent 21 at last. Herein the diameter of a cylindrical member 3 is made to be in a such a proper dimension as to limit the movement of bubble 6 in such a manner that the bubble comes into contact with the member 3 before it leaves the indent 21, and thereby this sensor is made easy to use. While the inside of an upper cover 2 is made a flat surface, it may also be a recessed surface having a limited radius of curvature.  Since the distortion of the bubble 6 corresponding to the inclination conforms to the recessed surface, in this case, it is smaller than that in the case of the flat surface.
