Title: Magnetic recording medium
Inventor: HORI TORU
IPC: G11B5/73
Filed: 1985-10-09
Abstract: PURPOSE:To provide a high S/N characteristic and high reliability by providing steps on a base of a medium for the part where an information signal is recorded and the other parts. CONSTITUTION:Grooves are provided only to the parts on a substrate 1 where recording is made. A magnetic coating compd. is coated over the entire surface of the substrate and the magnetic layer is ground until the projecting parts of the grooved substrate are thoroughly exposed. The pitch of the grooves of the substrate 1 is the same as a track width 5 of a magnetic head 4 and is so designed that the track of the head rises on the magnetic coating compd. 2 when a positioning error is zero. Since both sides of the track are of a nonmagnetic material, the head merely reproduces the signal recorded in the groove parts of the substrate 1 and does not read the noise after the DC erasure of the magnetic layer except the signal recording part. Both the high S/N characteristic and high reliability are thereby obtd. at approximately the same cost.

Title: Vacuum fluorescent display device and method of driving same
Inventor: YAMAGUCHI MASANOBU
IPC: H01J31/15
Filed: 1984-10-26
Abstract: PURPOSE:To obtain a device which makes dot display and picture display possible with a diode structure by arranging thermionic irradiation sources in a matrix shape, and directly controlling thermionic emission. CONSTITUTION:Thermionic irradiation cathodes are arranged in a matrix shape. When a voltage is applied to feeders of XK,...XK+3 and feeders of Yl,...Y1+3, the fluorescent screen of a portion which is opposite to the thermionic irradia tion cathodes of Ck,1+2, CK+1, l, CK+3, l makes luminescent display. On the other hand. in the thermionic irradiation cathodes of Ck, l, Ck,1+1, Ck,1+3, CK+1,1+1, CK+1,1+2, CK+1,1+3 etc., it is little possible to obtain thermionic, emission since the timing of applying voltage to X axial control feeders and Y axial feeders is not synchronized, and therefore the fluorescent screen of a portion opposite to these thermionic irradiation cathodes does not luminesce. Thus, the thermionic emission is carried out from only an optionally thermionic irradia tion cathode which is selected by applying two voltages to the feeders for con trol in time-sharing, and therefore it is possible to make the luminescent display in only desired fluorescent screen.
