Title: Gradation display method for video signal and display device using the same
Inventor: NAKA KAZUTAKA
IPC: G09G3/28
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To reduce picture quality deterioration due to false outline noise in gradation representation of a subfield system. SOLUTION: Digital data of an input video signal are supplied to a subfield converting circuit 2 and the respective bits of the data are assigned to subfields set in one field to generate subfield data. In this case, high-order bits having weights of a value obtained by equally dividing the total of the values of bits from the most significant bit are generated and assigned to different subfields. When gradations are low, the light emission period of pixels is determined by a combination of low-order bits of the subfield data, but when the gradations are high, the light emission period of the pixels is determined by a combination of the high-order and low-order bits of the subfield data, and consequently a gradational display is made, but high-order bits which contribute to the light emission of the same pixels are made different between adjacent pixels or in odd/even fields.

IPC: G11B23/093
Filed: 1989-12-20
Abstract: PURPOSE: To obtain a high data transmitting speed using a helical scarming by fixing a means for detecting and incorporating information of a magnetic tape to a prescribed position with respect to a drum and providing with a magnetic head brought into contact with the magnetic tape in the opposite side of an annular groove. CONSTITUTION: A tape reading/writing assembled body 20' is provided in the external part of a tape drum 10', and one or more number of magnetic heads 21 are included in the reading/writing assembled body 20' in order to read and write for the magnetic tape 14'. When the tape drum 10' is rotated to a base 12' and the magnetic head 21, a circular path on the cylinder type outer diameter surface 24' of the tape drum 10' is tracked with the magnetic pole of the magnetic head 21. However, since the magnetic tape 14' is transfered along a hel ical rurming path around the tape drum 10', the magnetic pole of the magnetic head 21 is made to track along an inclined path on the magnetic tape 14' to execute a helical scanning for the tape.  By this way, when the tape drum having a relatively large diameter is used, many magnetic heads are arranged around the periphery of the tape drum, and the high data transmitting speed is obtained.

IPC: G01R33/02
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To provide electromagnet control equipment and a method for controlling electromagnet, in which the time required for detaching a chucked body is shortened and residual magnetism of the material is lowered, by controlling voltage or current applied to an exciting coil of an electromagnet that demagnetizes the chucked body at the detaching, based on the detected value from a magnetism sensor. SOLUTION: In detaching a chucked body 3 from an electromagnet 5, a control circuit 6 applies first voltage, based on the data memorized in a memory 7, to an exciting coil 12 of an electromagnet 5 during first period of time, wherein polarity of the first voltage is opposite to that applied during holding period. The control circuit 6 receives detection signal from a magnetism sensor 8 in the first period of time. Based on the detection signal, the control circuit 6 calculates second voltage and second period of time, and applies the voltage to the exciting coil 12 of the electromagnet 5. The same operation is repeated until the residual magnetism detected after the second period becomes lower than approximately 5 gauss. By this constitution, it is possible to shorten the time required for the detaching, and to lower the residual magnetism of the material.
