Title: Manufacture of extra-low boron steel by refining
Inventor: TSURUOKA SHIGEO
IPC: C22C33/04
Filed: 1983-05-31
Abstract: PURPOSE:To manufacture a low B steel with little brittleness by deoxidizing a molten steel discharged from a steel manufacturing furnace up to a specified oxygen content and by adding an alloy material for regulating the composition. CONSTITUTION:A molten steel discharged from a steel manufacturing furnace into ladle is deoxidized up to 100-400ppm O2 content by adding Fe-Mn, Fe-Si, Fe-Al or the like. After discharging molten slag from the ladle, a necessary ferrroalloy is added to regulate the composition of the molten steel. No boron is restored from molten slag, and since the O2 content is proper, very little boron enters the molten steel from the ferroalloy for regulating the composition. A low B steel free from defects such as red shortness due to Fe2B is obtd.

Abstract: PURPOSE:To eliminate the influence of the transfer function of a vibrating table control system and to correctly reproduce a target input waveform by making close the inverse transfer function of the vibrating table servo system with a digital filter and inputting a target waveform through this to the servo system. CONSTITUTION:The transfer function of a vibrating table control system when an input wave signal related to an exciting wave signal is given through a digital filter 6 to the servo system of a vibrating table 1 is displayed as the product of the transfer function of the digital filter 6 and the transfer function of the digital filter 6. First, without passing through the digital filter 6, the vibrating table 1 is excited and the transfer function of the vibrating table control system is obtained by a transfer function measuring instrument 15. The characteristic of the digital filter 6 is set by a gain controller 16 so as to become equal to the inverse transfer function of the obtained transfer function. Thereafter, the input wave signal is given through the digital filter 6 to the servo system of the vibrating table 1. Thus, the influence of the transfer function of the vibrating table control system is eliminated regardless of the data length and type of a target input waveform and the target input waveform can be correctly reproduced.

Title: Method for generating movement locus image
Inventor: NAKATSUKA MASAMI
IPC: G01S7/295
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To make an image showing a movement locus of a target always disappear in a predetermined time. SOLUTION: When a memory cell (a) is selected at a first scan to a display memory as an object an image data of which is to be erased, the memory cell (a) is removed from an erasure object selection range at a second scan and afterwards. When a memory cell (b) is selected as the erasure object at the second scan, the memory cells (a) and (b) are removed from the selection range at a third scan and afterwards. When a scan count exceeds a predetermined value, an image data related to a movement locus of a target disappears from the display memory, and therefore the movement locus of the target is surely erased on a screen of a display apparatus within a predetermined time.

Title: Reproducing circuit of carrier wave
Inventor: MISHIRO TOKIHIRO
IPC: H04L27/227
Filed: 1982-06-08
Abstract: PURPOSE:To reproduce a reference carrier wave from a 2-phase modulated wave and to realize the share between 4-phase and 2-phase, by providing a switching circuit to one side of an orthogonal control signal system of a costas type carrier wave reproducing circuit which reproduces a reference carrier wave from a 4-phase modulated wave. CONSTITUTION:An operation same as a conventional costas loop is ensured when a switch 13 is closed. When the switch 13 is opened, the output of an adder 12 is equal to the waveform (C) obtained by obtaining a product through a multiplier 10 between the waveform (B) of an LPF4 and the waveform (A) of a comparator 9'. The output of the adder 12 moves to a point (i) and (j) when the digital value is 0 and pi respectively and has the same function to have the synchronism for the phase of a VCO7' since the place where the value 0 cuts is set in the same phase changing direction. Thus the VCO7' is set under a stable phase synchronizing state. A reference carrier wave is reproduced also from a 2- phase modulated wave with the output of the VCO7'.
