Title: High-uniformity magnet device
Inventor: BAN ETSUO
IPC: H01F7/00
Filed: 1979-07-16
Abstract: PURPOSE: To produce a magnetic field uniform in a wide range between magnetic poles, by setting the intensity of the magnetic field on the central plane between projections on the edges of the opposed magnetic poles so that the intensity is higher at the edges than at the central sections.  
     CONSTITUTION: When it is supposed that the distance from magnetic pole members to the central plane M between the magnetic poles is 1, there is a prescribed relationship among the width n of annular projections, their thickness m and the allowable variation range ±ΔH of the intersity of magnetic field and the relationship can be expresed with ΔH as a parameter. The width m and the thickness n are selected from an expressed curve. Appropriate compensation is effected for the edges of the magnetic poles depending on ΔH. This results in enlarging a region of high uniformity in magnetic field further.

Title: Record terminal detector
Inventor: KOBAYASHI RIICHI
IPC: G11B19/14
Filed: 1986-04-18
Abstract: PURPOSE:To detect the terminal of a record without being affected by eccentricity and external oscillation, by including a shielding plate which changes the extent of shielding in accordance with rotation of a tone arm and a photointerrupter to which the light is intercepted by the shielding plate. CONSTITUTION:A photointerrupter 1 is shielded by a shielding plate 6 so that the output of the photointerrupter 1 is linearly changed according as a tone arm 5 is moved inward, and the photointerrupter outputs the output proportional to the position of the arm, and the output becomes, for example, an output (c). Consequently, the output of a comparator 7 is inverted in the position, where a slope output (b) crosses the output (c) of the photointerrupter, and becomes a waveform (d) and is inputted to a microcomputer 3, and the microcomputer 3 turns off a pulse signal (a) which is outputted till then. Thus, the microcomputer 3 reads in a delay time T from the pulse signal output to the signal (d) input. Since the delay time T is proportional to the extent of movement of the stylus tip of the tone arm 5, a sound groove, a leading-out groove, or the last groove is detected in accordance with the position of the stylus tip of the tone arm 5.

Title: Automatic level corrector
Inventor: KURODA TOKUJI
IPC: G11B20/04
Filed: 1992-04-10
Abstract: PURPOSE:To provide an automatic level corrector which correct level difference between the respective channels of video signals in the case of dividing a video signal into plural channels, recording those divided signals in a magnetic tape or the like and synthesizing them into one channel on the side of reproducing. CONSTITUTION:A lamp signal fetch circuit 2 fetches lamp signals inserted during the vertical blanking period of the respective channels of video signals. A lamp signal inverse function generating circuit 3 generates the inverse functions of the fetched lamp signals. A lamp signal judge circuit 4 judges whether the fetched lamp signal is normal or not. When it is not normal, a lamp signal inverse function correcting circuit 5 corrects the lamp signal inverse functions, RAMs 7 and 8 store the lamp signal inverse functions, and the levels of the respective channels are automatically corrected. Thus, the level is exactly corrected by preventing quality degradation caused by erroneous correction generated when the amplitude of the reproduced lamp signal exceeds the dynamic range of an A/D converter.
