Title: Method of filling space with permanent magnet powder
Inventor: MATSUO YOSHIO
IPC: H01F41/02
Filed: 1988-06-27
Abstract: PURPOSE:To fill the molding space of a die with a certain quantity of permanent magnet powder piled above the opening of the molding space uniformly in a very short time and manufacture a permanent magnet having excellent magnetic characteristics by a method wherein a solenoid coil is provided near the opening and an AC current is applied to it and the permanent magnet powder is magnetically attracted into the space to fill it. CONSTITUTION:A solenoid coil 20 and a magnetic pole 22 are provided near the opening of the molding space 18 of a die and permanent magnet powder 24 is piled above the molding space 18. If an AC current is applied to the solenoid coil 20, AC magnetic lines of force are induced as shown by broken lines and an AC magnetic field is produced in the permanent magnet powder 24, the molding space 18 and so forth. The permanent magnet powder piled above the molding space 18 is magnetically attracted into the space 18 by the AC magnetic field and, while the permanent magnet powder repeats the complex vibration caused by the reaction with the AC magnetic field, even a very narrow gap is filled with the powder in a short time. Therefore, the molding space can be filled with the permanent magnet powder quickly and a permanent magnet can be molded very efficiently.

Title: Waveform shaping circuit
Inventor: ITOU TAKASHI
IPC: H03K5/08
Filed: 1982-09-14
Abstract: PURPOSE:Tu ensure an accurate waveform shaping operation despite a large waveform distortion of an input signal, by superposing the output of a comparator on a binary input signal after integrating it under the prescribed conditions and making a binary decision by the optimum threshold voltage in accordance with a DC bias signal supplied from an itnegration circuit. CONSTITUTION:A CMOS inverter has the characteristics as shown in the diagram, and a comparator 36 gives a binary decision to a signal 204 with the 2.5V threshold voltage. If the duty ratio of an H level signal is set at about 40% for an output signal 206, the average voltage VE of the signal 206 is equal to 2V. The integration voltage VD of an integration circuit 32 is turned into a bias signal 202 and then superposed on a signal 200. The voltage 204 increases as the voltage VD increases. When the voltage of the signal 202 increases, the reference voltage VT1 of an inverter 38 drops relatively to the signal 200. Then the H level duty ratio increases for a waveform shaped signal delivered from an inverter 40. This operation is repeated to obtain stability with a 50% duty ratio. The threshold volage VT1 with which the comparator 36 performs a binary decision is relatively set at an optimum level by the increase and decrease of the input signal 200. Thus it is possible to shape the wave form automatically regardless of the waveform distortion.

Title: Image correction circuit

Filed: 1989-06-22
Abstract: PURPOSE:To obtain an image signal whose shading is always corrected appropriately by detecting the shading state of the image signal after applying shading correction, and varying a correction signal to be inputted to a divider corresponding to the above state. CONSTITUTION:A maximum level detector 13 detects the maximum value of the envelope of the image signal, and its output signal is inputted to a subtractor 14. The subtractor 14 outputs a signal in which the level of the envelope is subtracted from the maximum level of the envelope of the image signal, and its output signal is inputted to an adder 16. The adder 16 adds the output signal of a correction signal generator 15 on the output signal of the subtractor 14, and its output signal is inputted to a divider 11. The divider 11 corrects the shading of the image signal by dividing the image signal outputted from a photoelectric converter 10 by a shading correction signal outputted from the adder 16. Thereby, the shading of the image signal can be corrected appropriately.
