Title: Operation of vacuum degassing treatment
Inventor: INOUE MAMORU
IPC: B01D53/04
Filed: 1988-02-19
Abstract: PURPOSE:To reduce unit requirements of oxygen and a deoxidizing agent and to obtain high purity gaseous CO by stopping blowing into a converter at the time when the amt. of C in molten steel is slightly higher than that in an end product, allowing C to react with oxygen in the molten steel and producing gaseous CO by vacuum degassing treatment. CONSTITUTION:Inert gas or the like is blown into a converter and molten steel is subjected to vacuum degassing treatment. Blowing is stopped at the time when the amt. of C in the molten steel is slightly higher than that in an end product. Gaseous CO is then produced by carrying out vacuum degassing treatment until the desired amt. of C is attained. The produced gaseous CO is recovered.

Title: Rotary cylinder for video tape recorder
Inventor: KOJIMA TAIZOU
IPC: G11B5/52
Filed: 1983-03-02
Abstract: PURPOSE:To prevent a magnetic tape from contacting with the edge of a space part by the pressure of an air film between a rotary cylinder and the magnetic tape by cutting away the circumferential part of the cylinder in a groove shape near the head position of the cylinder. CONSTITUTION:The circumferential part of the rotary cylinder 4 which has an axial center in the direction of an axial line A-A is cut away. This axial line A-A is directed in the tangential direction of the rotation of the rotary cylinder 4. A ground part 9 is formed so that this cylindrical shape overlaps a space part 8. For this purpose, only the circumferential part near the edge 7 of the space part 8 is cut away in the groove shape and moved back inwardly. Further, removed parts on both ends of the ground part 9 are slightly and the rotary cylinder 4 is removed greater toward the center. Therefore, the variation in flow passage area of air is made smaller where the head is positioned than before to reduce variation in air pressure, thus reducing the waving of the tape.

Abstract: PROBLEM TO BE SOLVED: To obtain a picture having a required aspect ratio through the aspect ratios of a picture display element and a required picture are different from each other by providing a magnify-projecting means capable of obtaining the magnified picture of a specific aspect ratio. SOLUTION: In the figure, a part shown by a dot line is the path of light and shows the path of respective dots A to C. The aspect ratio of the display element 1 is 4:3 and that of the display part 4 is 16:9. Thus, a picture obtained from the display element of 4:3 is magnified and displayed by 16:9 at the same time. Then, the picture of the element 1 is projected by 16:9 through the use of a lens 9. At this time, a projection system varying the magnification of a horizontal direction and a vertical direction are constituted. In another projection system, a lens 10 magnifies the picture by the same ratio concerning both of a vertical direction and right/left direction and after then reduces only the vertical direction by using a lens 11 having an effect of reducing only the vertical direction.

Title: Cylinder for internal combustion engine
Inventor: HIRAOKA TAKESHI
IPC: C23C4/18
Filed: 1981-03-13
Abstract: PURPOSE:To heighten the wear and scuff resistance of a cylinder having a flame-sprayed layer on the inside surface, by making the void ratio of the flame- sprayed layer different between its part near the top dead center and its other  part. CONSTITUTION:A flame-sprayed layer 2 is provided on the inside surface 11 of a cylinder. To improve the lubrication on the part of the flame-sprayed layer 2  near the top dead center during the operation of the engine which is server on  said part at the top dead center, the void ratio of the part of the flame-sprayed  layer 2 is set at 20-30% and that of its other part is at set at 10-15%. If the void ratio of the part of the flame-sprayed layer 2 near the top dead center  were set at less than 20%, the layer would not function as an effective oil reservoir and the resistance of the cylinder to the wear and scuff not would not  be improved. If the void ratio of the part of the layer 2 were set at more than  30%, the roughness of the surface of the layer would be so high as to promote  the wear of the piston ring which slides on the layer.

Title: Pid controller
Inventor: MURATE TSUNEO
IPC: G05B13/00
Filed: 1987-02-20
Abstract: PURPOSE:To realize the response with improved controllability for a PID controller by calculating the waste time and a primary delay time with process identification for comparison between both times and applying the PID control to a process based on the set optimum parameters. CONSTITUTION:A process identifying means 2 calculates the waste time L and the primary delay time TL and a parameter setting means 3 compares both times L and TL with each other to decide whether a process is controlled by the time L or the time TL. Based on this deciding result, the gain K, the integration time Ti and the differentiation time Td serving as the PID (proportion, integration and differentiation) parameters are calculated. Then a PID control means 4 calculates the manipulated variable MV corresponding to the input deviation from those parameters K, Ti and Td and outputs the MV to perform the control to the process. Thus it is possible to attain the response with improved controllability.

Abstract: PURPOSE:To enable sure commutation of SCR, by reducing the adverse effect of the inductance component of circuit on the turn-off time of SCR, through the small sized transformer construction. CONSTITUTION:The transformer T2 is made smaller in size by separating it to the transformer T1 giving the back bias voltage to the thyristor CR and the transformer T2 turning on QM giving the base current of a small value to the commutation transistor QM.
