Title: Rotary head mechanism and tape shaped recording medium
Inventor: FURUKAWA MASANOBU
IPC: G11B5/52
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To obtain a lead shape improving track linearity by presetting a lead height of a guide lead lower by a prescribed quantity than a prescribed lead height recommendation value so as to correct a deviation value of track linearity owing to elongation of a magnetic tape. SOLUTION: This rotary head mechanism is provided with a fixed drum 2 as a lower drum which is arranged facing an upper rotary drum so as to form a gap through which a magnetic head passes between the upper drum and the lower drum, and a guide lead which guides a magnetic tape to a prescribed tracking position with respect to the magnetic head is formed in the fixed drum 2. A lead height H1 of the guide lead 31 is preset so as to become lower by a prescribed quantity (h) than a lead height recommendation value H0 in order to compensate a deviation value of track linearity owing to elongation of the magnetic tape, and moreover a shape of the guide lead 31 is formed into a slightly upward projected curve. The track becomes linear in a state in which tension of the magnetic tape is eliminated.

On the other hand, a focus error signal which is detected due to the movement of the actuator is linearized. Then, a feedback control operation is performed in such a way that the position deviation between a linearization position output after its correction and the reference position shown in (A) is reduced.

IPC: G02F1/133
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To display an image on the same liquid crystal panel even with a video signal different in the number of scanning lines by changing the superposition number of scanning lines temporarily by one. SOLUTION: In waveform when the basic superposition number (n) is 1, that is, non-superposed, the pulse number of a superposition number signal P3 is 1, the pulse width of a superposition number switching signal P4 is 1H, and a scan timing signal P5 is reversed every 1H and rests from reversing once at the timing of superposition number switching signal P4. S1-S8 out of a common electrode drive signal group of a common driver usually have the superposition number (n)=1, that is, perform simple scanning, and have the superposition number = 0 at the timing of the superposition number switching signal P4, that is, are put in a nonselective state, which results in thinning out a video signal by the 1H portion. Dotted lines indicate rising timing of the signals in the case of not being thinned out.  Even with a video signal different in the number of scanning lines, an image can be displayed on the same liquid crystal panel, and the superposition number can be selected according to a user's preference.

Title: Shadow display method and apparatus
Inventor: NOOMAN DENISU RICHIYAADOSU
IPC: H04N1/21
Filed: 1987-12-24
Abstract: Pixel information representing an image for display is coded using data compression. The data compression consists in obtaining the pixel information as a first matrix of high resolution pixel values, subtracting from this first matrix a second matrix composed of lower resolution pixel values, produced by low pass filtering the first matrix, to produce a third matrix of difference values, sub-sampling the second matrix to produce a fourth matrix of less density lower resolution pixel values and coding the third and fourth matrices. Complementary decoding consists in restituting the second matrix by interpolation filtering the decoded fourth matrix, and combining the restituted second matrix with the decoded third matrix. Loss of accuracy in the decoding method is reduced by coding and then decoding the fourth matrix during the coding method before it is interpolated to full pixel density to form the restituted second matrix which is subtracted from the first matrix to produce the third matrix of difference values. In this way, any sub-sampling and interpolation errors in the restituted fourth matrix occur in both the coding method and the decoding method and therefore cancel out. Figure 3 illustrates the coding method including these coding and decoding steps.

Title: Magneto-optic head
Inventor: MURAKAMI YUTAKA
IPC: G11B7/085
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To prevent a relative position error between a light spot and a magnetic field applying means from being generated by rotating an optical head and a magnetic head in one body so as to follow up an eccentric component of an information recording medium. SOLUTION: So that the laser spot formed by the optical head 1 follows up surface waving and eccentricity of a magneto-optic disk, a focus driving device 10 and a tracking driving device 11 perform focus control and tracking control over an objective. At this time, the optical head 1 and magnetic head 12 are coupled by a coupling member 14, so the magnetic head 12 also rotates on an axis 9 of rotation. Therefore, a position-adjusted optical axis and the center axis of the magnetic pole end surface 3a in the center of a core 3 are always aligned with each other. Thus, rotation in one body on a plane parallel to an information recording medium is enabled to prevent the light spot and magnetic field applying means from shifting in position from each other when the eccentricity of the magneto-optic disk is followed up, thereby making the magnetic field applying means small-sized.
