摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display device consuming low power.
SOLUTION: When the liquid crystal display device displays a picture, odd- numbered signal lines 4 are connected with a column driving circuit 9 by change- over switches 5, and when it displays the next picture, even-numbered signal lines 4 are connected with the column driving circuit 9 by the change-over switches 5. Therefore, a plurality of the signal lines 4 is thinned out to half to drive so that the circuit scale of the analog column driving circuit can be made to half and the power consumption can be reduced.

摘要： PURPOSE:To eliminate a need of a magnetic field inverting motor to simplify and miniaturize the structure by providing an exciting coil, which generates torque, in the vicinity of a permanent magnet which impresses a bias magnetic field. CONSTITUTION:Plural exciting coils 4a-4c and exciting coils 5a-5c consisting of soft magnetic materials are provided in the vicinity of a permanent magnet 2 which impresses the bias magnetic field. In case of the change of the polarity of the bias magnetic field at the time of recording and erasing, currents flows to exciting coils 4a and 4b so that magnetic poles 501a and 501b are the S pole and the N pole respectively, and the N pole of the magnet 2 is attracted to the magnetic pole 501a to turn the magnet 2 at 90 deg. clockwise. Next, currents flow so that a magnetic pole 501c is the N pole, and the magnet 2 is turned at 90 deg. furthermore to invert magnetic poles. Thus, the inverting motor is unnecessary and the structure is simplified to miniaturize the device.

摘要： PURPOSE:To obtain a reproducing signal without a waveform distortion even when magnetic saturation is generated in a main magnetic pole, by providing a nonmagnetic and conductive film at the side of the main pole facing with a complementary magnetic pole. CONSTITUTION:The lower end plane 5a of a main magnetic pole 5 is faced with the magnetizing layer 2 of a recording medium 1, and performs a recording and a reproduction. Also, at the plane 5b of the main magnetic pole 5 facing with a complementary magnetic pole 6, a non-magnetic and conductive film 10 is provided. Meanwhile, the upper end plane of the main magnetic pole 5 is joined with the horizontal piece 60 of the main magnetic pole 6. In such a constitution, efficiency is improved because a magnetic path 8 in a recording and a reproducing time forms a closed magnetic path passing through a magnetic layer 3 with high permeability in the medium 1. Also, when a coil 7 is excited strongly in order to apply a stronger magnetic flux on the layer 2, the magnetic saturation is generated in the magnetic pole 5, and the magnetic path 81 which tries to pass the plane 5 is generated, and it tries to remain a magnetic component in a horizontal direction at the layer 2. However, an eddy current 11 is generated by the film 10, and a magnetic path 82 in the negating direction of the magnetic flux trying to pass the magnetic path 81, is formed, and the magnetic flux which passes the medium 1 passes the magnetic path 82 only in a thickness direction.

摘要： PURPOSE:To obtain a vertical magnetic head which can reduce the distortion of a reproduced waveform by securing a curve of the edge part opposite to a main magnetic pole on a counter surface of an auxiliary magnetic pole against a track part. CONSTITUTION:A lower end face 6a of a vertical bar 61 of an auxiliary magnetic pole 6, i.e., the counter surface against a track part has an area larger than a lower end face 5a of a main magnetic pole. At the same time, an edge part 6b opposite to the pole 5 has a curve on a counter surface of the pole 6 against the track part. Thus the part 6b is not parallel also to a recording signal pattern but curved. Therefore just a small number of signals are picked up at the part 6b. This reduces the distortion of a reproduced waveform.

摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of realizing a high quality image display. SOLUTION: This liquid crystal display device 1 includes a liquid crystal panel 3, a display signal control part 7, a light source control part 6, a light source drive part 5 and a light source 4. A modulation circuit incorporated in the light source control part 6 outputs a pulse signal according to a synchronizing signal (vertical or horizontal) supplied from the display signal control part 7. A comparison circuit incorporated in the light source control part 7 compares the pulse signal with a backlight current of a power source. The current value of the power source is changed based on the comparison result. Thus, since the backlight current is changed steeply synchronously with the synchronizing signal, the response of an optical system is sharpened.

摘要： PURPOSE:To enable the recording with high accuracy and to improve the reliability by constituting the subject device in such a manner that leakage flux generated from an actuator is led to flow into a magnetic substance disposed on a side of an excitation element, so as not to influence upon the magnetic field of the excitation element. CONSTITUTION:At the time of recording information, a magneto-optical disk 4 is rotated, and a current corresponding to a signal is allowed to flow a modulation coil 2 of the excitation element 1 to give the disk 4 a magnetic field, and at the same time, the disk 4 is irradiated with laser light of a semiconductor laser 13. Now, the leakage flux generated from a permanent magnet 11 of the actuator 20 is transmitted through the disk 4 to pass through the magnetic substance 21 disposed on the side of the element 1 to flow back to the magnet 11. Consequently, magnetic flux of the magnet 11 can be never reach the element 1, giving no influence upon the magnetic field generated by the element 1, and hence the disk 4 is recorded only by the magnetic field of the coil 2. By this method, the magneto-optical disk can be recorded with high accuracy and the reliability is improved.

摘要： PURPOSE:To reduce the load of the elevating means of a cartridge and the driving means of a core by providing a core to move in the direction along which said core moves to or retreat from the recording surface of a magneto- optical recording medium and a coil to surround the core and non-movable in the above-mentioned direction. CONSTITUTION:When a cartridge 3 is inserted into the driving device of a disk, it is held at a cartridge elevating part 5 and descended. At this time, a core 2 is also interlocked and descended. When the cartridge 3 arrives at the descending edge, the core 2 is descended further by a driving means along a sliding groove 5a and the tip is approached into an aperture part 3a. At this time, the coil 1, since it is fitted at a coil supporting plate 1a, is fixed as it is and become non-movable. Thus, it is not necessary to elevate the heavy coil.

摘要： PURPOSE:To reduce heat generation and current consumption by equipping the title device with a permanent magnet to generate a magnetic field having a direction to negate another magnetic field from a magnet for an actuator. CONSTITUTION:Actuators 7 and 7, which are driving means to move a lens 5 in a diameter direction and a vertical direction, are provided for the circumference of a lens 5. Further, a core 2 is provided for the upper surface side of a disk medium 4, and a coil 1 is wound around the center part of the core 2. Further, bar-shaped permanent magnets 3 and 3 are provided for the lower side of the coil 1, and the intensity and the directions of the magnetic fields of the permanent magnets 3 and 3 are determined so that the magnetic fields can negate the magnetic fields of magnets 7b and 7b for the actuators. Consequently, since the magnetic fields from the magnets 7b and 7b for the actuators to compose the actuators 7 and 7 to drive an objective lens are negated by the permanent magnets having polarity having an opposite direction to that of the polarity of the magnets 7b and 7b, the influence of the magnets for the actuators can be removed. Thus, it becomes unnecessary to impress an additional bias magnetic field for negating a leakage magnetic field, and the heat generation and the current consumption can be reduced.
