Title: Production of iron oxide for ferrite
Inventor: SASAKI HIROYUKI
IPC: C01G49/02
Filed: 1986-01-14
Abstract: PURPOSE:To obtain the titled iron oxide composed of Fe2O3 in a short time in high efficiency and productivity with a simplified apparatus installable in a small space, by carrying out oxidizing calcination of mill scale simultaneous to fine pulverization in a hot treating furnace. CONSTITUTION:Mill scale composed of about 50wt% FeO and about 50wt% Fe2O3 is transferred from a raw material hopper 1 to a screw conveyor 2 and passed through a magnetic separator 3 and a vibration sieve 4 to remove impurities, metals, coarse ingredients, etc. The obtained crude raw material having particle size of <=500mu is roughly crushed with a continuous vibration mill 5 to a size of 10-50mu and sent to a buffer tank 6. The material is then transferred to a treating furnace 8 with a screw conveyor 7 and blasted with O2 ejected from an O2-supplying nozzle 81 and with high-temperature air and flame ejected from a jet burner 82 at an ultra-high speed. The mill scale is finely pulverized by this process and, at the same time, oxidized and calcined in an oxygen-rich atmosphere at 600-800 deg.C to form fine powder of Fe2O3. The product is sucked and transferred with a fan 9 through a duct 10a, a gravity collector 11, a duct 10b and a cyclone collector 13 and the obtained Fe2O3 having particle diameter of about 2mu is transferred by a screw conveyor 14, metered with a metering machine 15 and bagged.

Inventor: OTSUKA ISAO
IPC: H03C3/00
Filed: 1989-01-10
Abstract: PURPOSE:To decrease the capacity of a ROM and to quicken operating speed by providing a conversion table converting a phase angle in a range of a reference phase angle into an amplitude within a reference amplitude range corresponding to the phase angle. CONSTITUTION:A signal separation switching circuit 110, a conversion section 120 and a code correction circuit 130 are provided on the subject circuit. All the phase angles of a phase signal are converted into phase angles in a reference phase angle range being a specific range in all the phase angles, the phase angle/amplitude conversion is implemented with respect to the converted phase angle and the code is corrected by the information of the amplitude code at the conversion of the phase angle with respect to the converted amplitude. Thus, an LUT ROM used for the conversion section 120 is decreased by 2-bit at the input bit width and by 1-bit at the output bit width. Thus, the ROM capacity is reduced and the operating speed is quickened.

Patent JP-S62163102-A (JP)
Title: Control circuit
Inventor: ITO SEIICHI
IPC: G05B9/02
Filed: 1986-01-14
Abstract: PURPOSE:To avoid the generation of the control output due to a circuit trouble by securing such a constitution where the control output is produced only when both operation permission and instruction signals are supplied from a sensor and also only in case the operation instruction signal is produced again after the operation permission signal is once turned off. CONSTITUTION:When the input signal P1 is equal to an inhibition signal (level h) after the output signal given from a sensor is turned off, the output signal of an AND gate 1 is turned off. Thus an AND gate 2 is reset and the output signal Z is turned off. Then the signal P1 is equal again to the operation permission signal (level p) and therefore the gate 1 oscillates again to produce the rectifying output (q) when the operation instruction signal P2 is supplied continuously. However the gate 2 does not oscillate and therefore the output Z is kept off. Then the gate 2 oscillates only when an operation instruction is delivered again and the change S2 is produced.
