Title: Magnetic recording system
Inventor: NAGANO MASAHIKO
IPC: G11B5/012
Filed: 1983-03-17
Abstract: PURPOSE:To prevent a variation of a reproducing output level, which is caused by a variation of a reproducing head, by recording a signal to a magnetic recording medium by a head having a scanning width which is capable of forming a wider track than a reproducing scanning width, and also erasing the recorded track. CONSTITUTION:As for a narrow width head II having a head width T2, recording and erasion of a signal are executed by a wide width head I having a head width T1 of about two times. A signal recorded to a track on a magnetic disk is erased by the wide width head  I of the head width T1. This erasion is executed by the wide width head  I having the same head width T1 as a track width Tt of a signal to be erased, which is recorded already, therefore, an unerased part is generated on a track to be erased, due to deformation of the magnetic disk or roughness of a tracking servo. Even if this unerased part is generated, however, in case of the reproducing scanning by the narrow width head II, this head width T2 is sufficiently small against a track width Tt, therefore, a crosstalk is scarcely generated between said signal and a new signal recorded in this track.

Filed: 1986-02-27
Abstract: PURPOSE:To form a surface of a cell layer into a dense plane to prevent gases of impurities such as water or the like from being absorbed, by firing the cell layer at a process temperature higher than the conventional one for firing the cell layer at which the surface of a dielectric layer becomes molten. CONSTITUTION:A material, which is formed by mixing a low gamma material such as Al2O3, a crystalline glass of low melting point, a coloring agent comprising cobalt trioxide for enhancing the contrast of a discharge-display, is used to forma cell layer 24 on a dielectric layer 23. Thereafter, this cell layer 24 is fired at a process temperature higher than the firing temperature of the cell layer at which the surface of the dielectric layer 23 becomes molten, for example, at 510 deg.C or so in case that the conventional firing temperature of the cell layer is 440 deg.C and that of the cell layer 23 is 570 deg.C. Thus, because, the whole surface of the cell layer is covered with a glass film 23 caused by dissolution in a part of the molten dielectric layer 23 and becomes dense, gases of impurities such as water carbon dioxide and the like can be prevented from being absorbed.

Title: Reproducing device for multi-channel information
Inventor: TOKORO KIYOUSUKE
IPC: G06F3/06
Filed: 1989-02-23
Abstract: PURPOSE:To change the order of information to be transferred by writing the information into a prescribed area allocated to each channel and outputting the information to a buffer memory via a matched read address. CONSTITUTION:A matching address conversion means 8 converts a write or read address supplied to a buffer memory 3 so that this address gives an access to a prescribed area allocated previously to each channel. As a result, the write address received from a write address generating means 6 is converted by the means 8 and the information corresponding to a fixed channel is always written into a fixed area of the memory 3 even if the transfer order of information received from a large capacity memory 1 is changed. Furthermore the read address received from a read address generating means 7 is converted by the means 8 despite the variance of a writing area. Thus the information can be read out of each proper area for each channel.
