Title: Vertical shaft rice cleaner
Inventor: SATAKE TOSHIHIKO
IPC: B02B3/06
Filed: 1987-12-25
Abstract: PURPOSE:To smooth the flow of uncleaned rice into a cleaning room even when the density of rice grain in the cleaning room is changed through the operation of the rate-of-cleaning adjusting mechanism by making the external circumferential diameter of a spiral rotor larger than that of a cleaning rotor provided on the upper part of the said shaft. CONSTITUTION:The uncleaned rice supplied from a tank 31 to the spiral rotor 5 is sent to the cleaning room 19 and cleaned by the agitation of the cleaning rotor 6 to a prescribed rate of cleaning. The uncleaned rice discharged from the upper part of the cleaning room through a cleaned rice discharging gutter 23 to the external part of the equipment and the peeled rice-bran is discharged from a through hole of a porous cylinder 13 for removing rice-bran. When the rate of cleaning of the cleaned rice discharged from a cleaned rice discharging gutter 23 is not normal in such a rice cleaning operation, the density of rice grains flowing in the clean-room 19 is varied by manipulating a rate-of-cleaning adjusting mechanism, the cleaned rice discharged to the cleaned rice discharging gutter 23 is adjusted to a desired rate of cleaning. In this case, since the spiral rotor 5 is larger in the external circumferential diameter than the cleaning rotor 6, the flow rate of uncleaned rice to the cleaning room 19 does not vary.

Title: Overwritable magneto-optical recording medium
Inventor: MIYAMOTO JIICHI
IPC: G11B11/105
Filed: 1989-12-25
Abstract: PURPOSE:To obtain a large Kerr rotation angle by setting the Curie temp. of a first magnetic layer higher than the Curie temp. of a second magnetic layer. CONSTITUTION:The Curie temp. of the first magnetic layer 3 is made higher than the Curie temp. of the second magnetic layer 4. Since the magneto-optical effect, namely the Kerr effect, becomes large as the higher Curie temp. of the first magnetic layer 3 is higher, the direction of the magnetic field for recording is set opposite to the direction for which the directions of magnetization in the first magnetic layer 3 are made uniform when the layer 3 is irradiated with laser beam of low intensity. Thereby, a large Kerr rotation angle can be obtained without decreasing the recording sensitivity.

Filed: 1989-12-21
Abstract: PURPOSE:To eliminate distorted sound even in use of an inexpensive LPF whose characteristic is not so much excellent by using a one-shot multivibrator and a logic gate to shape the waveform of output of a comparator eliminating a signal in middle and high sound frequencies. CONSTITUTION:An input signal passes through an LPF 1, in which only a required low frequency component is extracted and a signal at the output point F of a comparator 2 is converted into a logic signal. A signal at the point F has a waveform with a narrow pulse as shown in Figure (a) by a leaked signal component at medium high sound frequencies. The narrow pulse causes distorted sound by the operation of a T-FF3. In order to prevent such distortion, at first, a one-shot multivibrator (OS) 7 and a logic gate 8 erase the narrow noise and the OS 9 and the logic gate 10 correct the reduction in the pulse width attended with the erasure. On the other hand, the output of the LPF 1 is supplied to a rectifier circuit 5, the amplitude is detected and the output of an LPF 4 is controlled by a VCA 6 so as to be proportional to the amplitude, as a result, the signal whose frequency is a half that of the input signal and whose amplitude is proportional to the amplitude of the signal is obtained.

Abstract: PROBLEM TO BE SOLVED: To make a high-quality control of an induction machine available by outputting secondary magnetic flux with the inputs of induction machine voltage and current, a primary resistance, a primary and a secondary self- inductance, and a mutual inductance and outputting a secondary time constant with the inputs of the secondary magnetic flux, the induction machine current, and the mutual inductance. SOLUTION: A magnetic flux calculator 9 outputs secondary magnetic flux Ψ2 with the inputs of the induction machine voltage (v) and current (i) and a preliminarily given primary resistance R1, primary self-inductance L1, secondary self-inductance L2, and mutual inductance M. A time constant calculator 10 outputs a secondary time constant T2 with the inputs of the secondary magnetic flux Ψ2, the induction machine current (i), and the mutual inductance M. Since DC current is caused to flow in a secondary circuit, measured values of the secondary time constant T2 and secondary resistance R2 are the ones which are close to those at the normal operation of the induction machine. And, a voltage detector 3 detects or estimates the voltage V when the induction machine 4 is rotating at nearly a rated rotating speed, and therefore there is only a little error by the voltage detector 3.
