Patent JP-S57199474-A (JP)
Title: Controller for power reversible converter
Inventor: MAEDA KEIJI
IPC: H02M7/48
Filed: 1981-05-29
Abstract: PURPOSE:To prevent the generation of the short circuit of a power supply by mounting a gate signal distributing circuit stopping the transmission of gate signals when the logic levels of the output of the first and second flip-flop circuits agree. CONSTITUTION:When there happens trouble in the NAND circuit 12A of the flip-flop circuit 11F at t time and QA output changes to logic (1) from logic (0), the QB output of an NAND circuits 12B changes to (0) from (1). Since the flip- flop circuit 11R maintains the original condition, two input to an exclusive-or circuit 14 reaches (1), and output EX reaches (0). Accordingly, since AND gate circuits 13F, 13R are closed, the output of gate signals GF, GR is stopped, both thyristor circuits THF, THR cannot transmit gate signals and the generation of the short circuit of the power supply can be prevented.

Abstract: PURPOSE:To perform automatic focus adjustment with a device made smaller in size, by providing a main image pickup element and secondary image pickup element on the same surface to perform the focus movement of light image formed on the secondary image pickup element, and adjusting automatically the focus of the main image pickup element at a position where the amplitude of the high-frequency component of an output signal shows the maximum value. CONSTITUTION:The light image of an object 101 is formed on a main image pickup element 104 by a focus adjusting lesn 102 and an eyepiece 103, and the part of it is diffracted by a half mirror 106 and formed its image on a secondary image pickup element located on the same surface as that for the element 104 via a focus moving lens 108, vertical direction comporession lens 71 and mirrors 72 and 73. The forcus of the light image formed on the secondary image pickup element is adjusted by moving a mirror 108, and a position where the amplitude of the high-frequency component of the signal out of its output terminal 105 shows the maximum value is detected by a maximum value detector 112. The detection signal is suplied to a comparator 115 via a smoothing circuit 114, and the focus of the element 104 is automatically adjusted by moving the lens 102. The read out of the secondary image pickup element is made to be the signal of the vertical interval signal of a standard television and outputted by time division with the output of the element 104.

Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To output a high-resolution image pickup signal directly to the input terminal of a projector not through a computer by reading digital video data stored in a buffer memory and converting the data into an analog signal through color spatial conversion. SOLUTION: A monitor discriminating circuit 28 discriminates the kind of a monitor and sends the discrimination result to a system controller 20. A changeover switch 24 determines whether data are read out of the buffer memory 17 in the timing of an interface controller 19 or monitor display timing controller 23. A D/A converter 25 converts the digital RGB signal outputted from an RGB matrix circuit 18 into an analog RGB signal. When the data of the buffer memory 17 are displayed on the monitor, the changeover switch 24 is set to the side of a monitor display timing controller 23 and the data read out of the buffer memory 17 are outputted to the monitor from the RGB matrix circuit 18 through the D/A converter 25.

Abstract: PURPOSE: To obtain a flux cored wire for welding which has high productivity without disconnection even if high-speed drawing is executed in the stage of a small diameter. CONSTITUTION: A flux composed of ferromagnetic raw material powder and weakly magnetic raw material powder at a specific compounding ratio is used as the basic prescription for the flux in this process for producing the flux cored wire for welding by supplying the flux to a tubular body during the course of forming metallic band steel to the tubular shape and joining the butt parts of the tubular body by high-frequency welding, then reducing the diameter. The flux is the plural divided prescription fluxes formed by at least bisecting this basic prescription to the first kind divided prescription flux 5 compounded with the weakly magnetic raw material powder and the second kind divided prescription flux 6 compounded with the ferromagnetic raw material powder.  The first kind divided prescription flux 5 is supplied to the upper layer side of the tubular body 3 and the second kind divided prescription flux 6 to the lower layer side of the tubular body 3. At least the second kind divided prescription flux 6 is pellets. In addition, iron oxide in the form of superfine powder of a grain size of <=1.0μm is incorporated into the second kind divided prescription flux 6 at 0.2 to 2.0% of the total weight of the filled flux.

Title: Slitter device provided with blade polishing function
Inventor: OKIMASA EIJI
IPC: B26D7/12
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To automatically perform in-line polishing at the suitable driving speed without affecting the production speed in polishing treatment for restoring the sharpness of a rotational cutting blade, in a slitter device for performing cutting by the rotational cutting blade to be rotated at speed higher than the feeding speed of a corrugated sheet. SOLUTION: When a cycle is shifted to a non-cutting cycle, knife discs in the polishing period are polished by an exclusive polishing device (an abrasive grinding wheel) for each knife disc in T40, T41. When a need to change the order is generated during polishing, the polishing operation is interrupted in T44, and a cycle is shifted to the cutting cycle after T45. The discs not yet polished at that time are polished after T40 when the cycle is returned from the cutting cycle to the non-cutting cycle, and therefore, polishing for discs requiring polishing can be reliably performed without affecting the production line.
