Abstract: PURPOSE:To plot a thick line provided with roundeness on both ends by plotting the line segment of set length with a point on respective circular arcs as a starting point in a direction determined based on the starting point and a terminating point set initially. CONSTITUTION:With a reference point as a center, the point on the circular arc whose diameter is its thickness is generated (SP2), one point on the circular arc is selected (SP3), the relative position of the selected point to the reference point is applied for the starting and terminating points and thus, the corrected starting and terminating points are obtained (SP4). Then, the line segment is plotted between the corrected starting and terminating points (SP5) and is corrected and then, whether or not processing for all the points on the circular arc is completed is discriminated (SP6). When it is discriminated that the point to which the processing is not performed is present, the other point on the circular arc is selected (SP7) and the processing for obtaining the corrected starting and terminating points is performed again. On the other hand, when it is discriminated that the processing for all the points on the circular arc is completed, the processing is completed.

Title: Loading motor stopping device in magnetic recording and reproducing device
Inventor: KABURAGI TSUKASA
IPC: G11B15/675
Filed: 1985-10-14
Abstract: PURPOSE:To stop a loading motor effectively in a short time without overshooting of a desired mechanical mode by applying an inversion braking of a prescribed quantity immediately after a switch is closed or after a delay of a prescribed time. CONSTITUTION:When a microcomputer changes a command A to 'L', a charge of a capacity 58 is started, a waveform of an input R1 is shaped 60 and a capacity 62 is charged as making a NAND61 'H'. At this time, an input R3 is larger than a threshold VS2 of a NOT64 and its output R4 becomes 'L' to keep a charge of the capacity 62. When an input R3 is smaller than VS2 according to a resistance 63, R4 is changed to 'H', during 'L' period of R4, T1 is determined by an 'H' output VH of the capacity 62, the R1, the VS2, and the NAND. The R4 is made an 'H' output R6 through a NOT65 and the 'H' is applied to one of NANDs 56, 57. During the period T1, the command A goes 'L' and an R5 goes 'H', and a inversion signal of a B appears in an output R7 of an OR69, the inversion signal is produced in outputs D, E and the inversion braking is commanded. On a completion of the baking, the outputs D, E return to 'H'. According to the inversion signal, transistors 87, 88 are turned off and a terminal of a motor goes to 'H' to have a braking condition.

Title: Coordinate detecting part of coordinate input device
Inventor: GOTOU HIDEFUMI
IPC: G06F3/033
Filed: 1982-12-27
Abstract: PURPOSE:To reduce the cost and at the same time to prevent the deterioration of a coordinate position accuracy by forming an electric wire having a constant section area and minute width in a rectangular wave form within an effective coordinate reading region and using the resistance value generated between both ends of the electric wire for a coordinate detecting part. CONSTITUTION:A wire 10 having a constant section area and minute width is formed on an electrically insulated sheet 1 as shown in the figure. The both ends 11 of the wire 10 are used as electrodes. Thus a coordinate detecting part is formed, and therefore the resistance value is generated between terminals 12 and 13. Then numbers 1-m are given to the wire 10 in the direction X, and a potential is applied between the terminals 12 and 13. Thus the potential varies in a range of O-V1 on a thin wire 1 and in a range of V1-V2 on a fine wire 2 respectively. Then the output potential VP of a point P is converted into a digital form by an A/D converter of resolution (m). Therefore the digital quantity shows the number (n) of the thin wire at the point P and also shows the X coordinates. In such a way, the coordinate detecting part is formed in a simple process. Furthermore the deterioration can be avoided for the accuracy of the coordinate position.

Title: Supporting grid of nuclear reactor fuel assembly
Inventor: WADA NORIO
IPC: G21C3/34
Filed: 1987-09-10
Abstract: PURPOSE:To assure sufficient elastic force by blanking slots in such a manner that springs are formed to an S shape and projecting the springs to one side of a plate material so as to gradually increase the surface height of the springs. CONSTITUTION:The springs 8 are formed to the S shape when the plate material is blanked with U-shaped slots 15 oppositely to each other. Further, the springs are formed to project to one lateral face side of the plate material. Since the springs are formed to project to one lateral face side of the plate material, the overall length of the springs 8 is long and the elastic deformation quantity increases correspondingly. The springs 8 are successively taller than the surface of straps 13 nearer the central part 8m. A space 8a is eventually formed between the springs 8 and the straps 13. The space 8a functions as a water path for the cooling water flowing in the supporting grid and the cooling water receives less resistance by the springs. The sufficient elastic force is, therefore, assure even if a zircalloy material, etc., having low mechanical strength are used.

Then the undesired arithmetic items are designated to the displayed totalization result and then deleted selectively. Then the totalization result is compiled again in response to the necessary arithmetic items and displayed. Thus it is possible to surely secure a necessary range of the inter-card totalization result just with a simple input operation.

Abstract: PROBLEM TO BE SOLVED: To prevent electric field concentration through a simple process without increasing the gate resistance of a semiconductor device, by forming high-resistance areas having a nearly uniform thickness on the side faces of a gate in the longitudinal direction in a gate electrode in the joined-side area of the gate electrode. SOLUTION: A source electrode 12 and a drain electrode 13 are formed on a GaAs substrate 11 through an ordinary FET manufacturing process. Then a gate electrode 14 is formed between the electrodes 12 and 13. The gate electrode 14 is formed in a three-layer structure composed of a Ti layer, a Pt layer, and an Au layer form the bottom side. After the formation of the gate electrode 14, high-resistance areas 15 are formed by oxidizing both side faces of the lowermost Ti layer 14a into TiO2 through heat treatment. The high-resistance areas 15 are formed in the parts of the gate electrode 14 which are on the inside of the longest portion of the electrode 14 in the lengthwise direction and do not reach the upper surface of the electrode 14, but come into contact with the GaAs substrate 11.  When positive and negative voltages are respectively impressed upon the drain and gate electrodes 13 and 14, electric field concentration is relieved, because electric fields are dispersed at the lower corner section of the element 14 in the lengthwise direction.

Abstract: PROBLEM TO BE SOLVED: To minimize an effective area by joining and fixing a polarizer on at least one face of a Faraday rotator and polishing the end face of the polarizer to decrease the thickness of the polarizer, while the polarizer is joined and fixed to the Faraday rotator. SOLUTION: An optical part is produced by joining a first polarizer 1, a Faraday rotator 2 and a second polarizer 3. Both optical faces 1a, 1b of the first polarizer 1 and both optical faces 3a, 3b of the second polarizer 3 are subjected to reduction treatment of silver halides aligned on the faces to form a silver particle reduced layer on each face. Then the optical faces 1a, 3b, which are not the joining side of the first polarizer 1 and second polarizer 3 in the joined state, are subjected to mechanical surface polishing, and additionally as necessary, to mirror-polishing to decrease the thickness of the first polarizer 1 and the second polarizer 3. Thereby, by polishing a polarizing material, such as the first polarizer 1 and the second polarizer 2 in the joined state to reduce the thickness, the effective area of the optical part can be minimized.
