Abstract: A driving and positioning system consisting of a rotor equipped with permanent magnets and of a stator with at least two windings. The windings are connected to an electronic voltage-supply circuit controlled by rotor-position sensors for commutating the current. To improve its adjustment potential by converting the system into one that can be magnetically meshed or latched, the stator is non-ferrous, the disk-shaped stator windings, which are positioned in parallel planes, are overlapped in such a way that the magnetic field generated by the windings and surrounded by the coils is essentially parallel to the magnetic field generated by the permanent magnets, and the rotor-position sensors are each integrated into both windings. A practical electronic voltage-supply circuit for controlling the system is also described. It has two sets of multiplication stages and a set of addition stages in a prescribed layout.

Title: Waveform memory device
Inventor: SUZUKI TOSHIHISA
IPC: G01R35/00
Filed: 1982-02-24
Abstract: PURPOSE:To match outputs of bright lines with graduations on the surface of a CRT by correcting the gain and the offset with the calculation of errors therein from a deviation in the positions detecting them with a photoelectric conversion element when the bright lines are outputted on the CRT in varied voltages. CONSTITUTION:A fixed voltage is outputted on a CRT 1 as test signal through an output circuit 4 with a computation controlling circuit 3. At the same time, the position of the output is detected with a photoelectric conversion element 2 and the value is read into the computation controlling circuit. Then, a voltage different from the test signal is likewise outputted on the CRT 1 and the position of the output is detected with a photoelectric converter 2 to be read into the computation controlling circuit 3. Based on the difference between these two values, the circuit 3 calculates a deviation between the gain and the offset and outputs a value to correct the gain and offset. This automatically corrects the gain and the offset eliminating the deviation between graduations on the surface of the CRT 1 and the output positions.

IPC: C21C7/00
Filed: 1986-02-12
Abstract: PURPOSE:To improve the quality of a molten steel contg. alumina as a nonmetallic inclusion by agitating the molten steel with blown gaseous Ar and an agitator made of a CaO-base material so as to remove the alumina in the form of (CaO)m(Al2O3)n. CONSTITUTION:Gaseous Ar is blown into a molten steel contg. Al2O3 as a nonmetallic inclusion to agitate the molten steel. At the same time, the molten steel is agitated at >=1,500 deg.C with an agitator made of CaO, CaO-CaF2 or CaO- MgO. The Al2O3 in the molten steel reacts with CaO to form a composite compound such as (CaO)m(Al2O3)n and the compound is adsorbed on the agitator and removed. Even when part of the (CaO)m(Al2O3)n is dispersed in the molten steel, unlike Al2O3 the dispersed (CaO)m(Al2O3)n floats up and enters slag at a high rate because the melting temp. of (CaO)m(Al2O3)n is lower than that of Al2O3.

Abstract: PURPOSE:To desorb CO2 remaining in an adsorbent when an absorbing process in finished, into raw gas and besides, to recover CO2 gas having high purity from raw gas having a small CO2 content, by setting the pressure in an adsorbing tower than the adsorbing process is finished, at the pressure higher than the partial pressure of CO2 in the raw gas supplied in the adsorbing process. CONSTITUTION:The raw gas having a relatively small CO2 content is supplied 2, 21 to the adsorbing tower 11 and continued to supply by opening valves 711, 712, after increasing the pressure in the tower 11 to a slightly higher pressure more than atmosphere pressure (pressure increasing and adsorbing process). During this period, a washing process is carried out in an absorbing tower 13, and a desorbing process in an adsorbing tower 14. The adsorbing process in the tower 11 is finished by closing the valves 711, 712 and a released gas having a higher CO2 concn. than one in the raw gas is introduced from the tower 14 to the tower 11. The CO2 in the released gas is adsorbed with the adsorbent in the tower 11 after the adsorbing process and the residual waste gas is exhausted 3. As the result, the amt. of CO2 adsorbed with the adsorbent in the tower 11 can be increased than one at the end of the absorbing process.
