Title: Method of reducing oxide in iron powder without decarburization
Inventor: ERITSUKU SUTORESHIE
IPC: B22F1/145
Filed: 1993-05-26
Abstract: PURPOSE: To provide a process for preparing a carbon-containing oxide-free iron powder or iron-base powder where oxygen impurities are removed from iron powder without substantial decarburization. CONSTITUTION: The process consists of steps of: heating an iron powder or iron-base powder in an enclosure under a pure hydrogen atmosphere from room temperature up to a first intermediate temperature; replacing the pure hydrogen atmosphere in the enclosure by a pure nitrogen atmosphere; heating the iron powder or iron-base powder up to a second temperature higher than the first intermediate temperature; cooling the iron powder or iron-base powder under an inert atmosphere down to a temperature where no oxidation occurs; and removing the iron powder or iron-base powder from the enclosure. The first and the second temperature are the temperatures which are sufficient to reduce substantially all oxide impurities in the iron power or iron-base powder without substantial decarburization.

IPC: H01F10/10
Filed: 1986-05-29
Abstract: PURPOSE:To obtain an organic thin film material exhibiting magnetism, by applying the two-dimensional orientation aggregate forming ability of synthesis two-molecular film forming compound, and arranging regularly a metal ion complex having magnetic moment. CONSTITUTION:A complex forming a planar four-coardination structure in which copper or oxivanadium serves as a center metal and a matrix which has positive or negative charge and posseses property forming a two-mecular film are uniformly dissolved or dispersed in water by means of a supersonic treatment and the like. This solution or dispersion liquid is casted on a substrate, and dried gradually for several days in a desiccator. In this manner a thin film is easily formed. Setting the direction of film thickness as Z axis, ESR is measured in cases where Z axis is parallel to and vertical to the direction of magnetic field. Thereby magnetic anisotropy can be estimated and recognized. The thin film like this can be applied to, for example, a medium for various memories as a magnetic recording material, an absorber for electromagnetic waves, a small-sized transformer and motor, etc.

Title: Photoelectric conversion device
Inventor: SHINOMIYA KOJI
IPC: H01L31/02
Filed: 1986-05-29
Abstract: PURPOSE:To provide the title photoelectric conversion device capable of highly accurate photoelectric conversion by a method wherein the voltage of rear gates of MOS transistors converting short-circuit current of multiple photodiodes is equalized with the potential of mutually connected anode electrodes of photodiodes. CONSTITUTION:The short-circuit current generated in photodiodes 3, 4 is converted by means of a conventional circuit as usual, however, the voltage of rear gates of N-ch MOS transistors 2-1, 2-2 is equalized with the potential of anode electrodes of photodiodes 3, 4. Through these procedures, the potential difference between source, drain and channel parts of MOS transistors constituting a switch and the rear gates can be eliminated so that the leak current between the source, drain and channel part of this MOS transistors and the rear gates may be reduced approximately to naught. Resultantly, almost all short-circuit current generated in photodiode 3, 4 can be fed to another diode 8 to be converted into voltage providing the photoelectric conversion with high accuracy.

Title: Adjusting method for rotational position detector
Inventor: YURA MOTOSUMI
IPC: G01B21/22
Filed: 1993-04-30
Abstract: PURPOSE:To automatically adjust the amplitude difference between two phase sine wave signals by multiplying a speed detection error by the two phase sine wave signals and a two-multiplied sine wave signal and then extracting only a specific error component included in the speed detection error. CONSTITUTION:A gear 1 is rotated at a certain speed and a rotational position detected value 15 is differentiated to obtain a rotating speed detected value 17; and its mean value is further subtracted to obtain the speed detection error 21. Multipliers 24a and 24b multiply the error 21 by the A-phase and B-phase sine wave signals 18 and 19 to extract error components. Then a multiplier 24c finds the product of the signals 18 and 19, i.e., the two-multiplied sine wave signal 27. The product 27 is differentiated to obtain a 2nd two multiplied sine wave signal. Those two signals 27 and 28 are multiplied by the speed detection error and the results are smoothed to detect DC values corresponding to the phase difference and amplitude difference. Therefore, the amplitude difference can be adjusted by semifixed resistances 6c and 6d of the rotational position detector according to the smoothing output.

IPC: G05D7/00
Filed: 1977-10-20
Abstract: PURPOSE: To prevent abrupt change in the flow rate of water supplied, when a partition valve is opened and closed, by overlapping compensating pulses upon the opening of a regulating valve.  
     CONSTITUTION: When a flow rate setting signal exceeds a preset level, the signals indicative of the opening of a partition valve assume their full level to operate a relay 15 thereby to render a contact 16 conductive so that control pulses are overlapped upon a regulator valve opening command by the action of an adder 19 through a compensating pulse generator 18. The change from the full open to full closed condition of the partition valve opening signals is compensated instantly in response to the regulating valve opening signals so that the time for the restoration of the compensating pulses can be free from any disturbances by adjusting it with the time constant of a prime mover system and so that the speed change of the prime mover can be controlled to a low value.

IPC: G01S15/931
Filed: 1995-04-26
Abstract: PURPOSE: To greatly reduce ringing so as to improve detection sensitivity in a short range by impressing the second variable electric field with a different phase and a different amplitude in the thickness direction of a piezoelectric film and generating ultrasonic waves from the piezoelectric film. CONSTITUTION: A trigger pulse generator 191 triggers a one-shot multivibrator 199 so as to generate a pulse in a predetermined cycle for opening a gate 1, and an output (variable magnetic field) of an oscillator 192 is impressed to a piezoelectric film (converter), and then, ultrasonic waves are generated. An output pulse from the vibrator 199 is differentiated in a differentiation circuit 194 into a positive/negative sharp pulse so as to be outputted to a clipper 196 via an inverter 195. This signal triggers the second one-shot multivibrator 197 so as to open a switch 198 via a gate 2. Similarly, a switch 190 opens the gate 1, and a transmitter 192 impresses an output 2, whose phase is opposite to that of an output 1, onto the piezoelectric film. In this way, ringing can be canceled.
