Abstract: PURPOSE:To obtain a ferrite magnet having excellent magnetic characteristics, not causing a different phase in burned powder during ferrite formation at a high temperature, by grinding mill scale, primarily oxidizing, mixing the powder with Sr or Ba oxide or carbonate, secondarily oxidizing by a sloping type rotary furnace, and then burning. CONSTITUTION:Mill scale is ground into <=20mum of average particle size and primarily oxidized in an atmospheric pressure at 600-900 deg.C for 0.1-1.5 hours to change degree of oxidation of the mill scale into >=95%. The powder is mixed with Sr or Ba oxide or carbonate, secondarily oxidized by a sloping type rotary furnace with 8-10% amount of oxygen in an atmosphere at the inlet side of a raw material at the temperature up to 700 deg.C and then burnt at 1,275-1,300 deg.C for 15 minutes to one hour. A ferrite magnet using this raw material may contain <=2% of one or more of SiO2, Cr2O3, etc., as an additive so as to improve sintering properties or magnetic characteristics. In the case of containing impurities such as TiO2, MgO, etc., in the mill scale, processes such as magnetic selection and flotation are added.

Title: Method of setting digital speed reference of electric motor
Inventor: UMEMOTO FUJIO
IPC: H02P29/00
Filed: 1988-10-24
Abstract: PURPOSE:To obtain an adjusting speed reference pattern approximate to a required speed adjusting pattern without changing the time of acceleration and deceleration by calculating a fraction of speed increase, estimated from a condition of acceleration and deceleration, before starting the acceleration and deceleration and dividing correction of the fraction equally into two or more speed adjusting scans. CONSTITUTION:In acceleration and deceleration at a fixed rate by a cyclic scan from the present value v1 to the target value v2, when a difference between the values v1 and v2 is not an integral multiple of a standard speed reference increase  v per 1 scan, its fraction is divided into two or more scans and applied to the  v of those scans as the correction value. Thus a digital speed setter for a speed control device of an electric motor enables the adjusting speed setting pattern to be digitally set very approximately to the target pattern without changing the time of acceleration and deceleration.

Title: Method for controlling injection of injection molding machine
Inventor: OCHIAI KIYOTADA
IPC: B29C45/77
Filed: 1986-11-11
Abstract: PURPOSE:To prevent injection pressure from rising abruptly by a method wherein injection speed is controlled when the injection pressure, which corresponds to the position and holding time of a screw, is less than or equal to the set pressure, while injection pressure is controlled when the injection pressure is more than or equal to the set pressure. CONSTITUTION:When the reaction force to a screw 6 (or injection pressure Ps) is smaller than the output Pp of a pressure control valve 9, the screw 6 is speed-controlled by a flow control valve 8. As a result, the screw 6 is controlled by hydraulic flow rate so as to advance. On the other hand, when the injection pressure Ps reaches the set pressure Pp of the pressure control valve 9, the flow control valve 8 goes out of function and consequently the screw 6 is controlled by the pressure of the pressure control valve 9. As a result, the screw 6 advances under the control of hydraulic pressure. Further, at this time, the output Qp of the flow control valve 8 lowers to the state of Qp<=Qs (in which Qs is the rate of the flow supplied in an actuator). After that, when the injection pressure Ps becomes less than the output Pp of the pressure control valve 9, the flow control valve 8 functions again so as to control the screw by the valve 8, resulting in speed-controlling the screw 6 by hydraulic flow rate.

Title: Cutting tool abnormality detecting means in machine tool
Inventor: NAKAZAWA KOJI
IPC: B23Q17/09
Filed: 1985-11-29
Abstract: PURPOSE:To detect the abnormality of a cutting tool with high sensitivity and without impairing its cutting rigidity by detecting a thermoelectromotive between said cutting tool and a workpiece, measuring variation in its amplitude with respect to a feeding speed, and judging the abnormality of said cutting tool. CONSTITUTION:The detected value of thermoelectromotive between a cutting tool and a workpiece is frequency analyzed by a detected output processing part 15, and the relation of resonance frequency amplitude / feed speed is outputted to a comparator 17 and a monitor indicating device 18 as a detected output 15', by means of the result of the analysis and a feeding signal from a feed commanding part 14. On the other hand, a threshold value of the detected output 15' at each feed speed is previously set in a reference data memory 16, and a threshold value corresponding to a feed speed is outputted and compared by the comparator 17 and, if the detected output 15' is greater than the threshold value, a warning output 19 is outputted as the wear of the cutting tool is great. Since it is not necessary to outwardly insulate the cutting tool and the workpiece by means of an insulating material, the cutting rigidity is not impaired.
