Title: Plasma electrode
Inventor: FUJIWARA TAKAMASA
IPC: H01L21/31
Filed: 1989-05-18
Abstract: PURPOSE:To improve the uniformity of a film thickness in a batch by a method wherein dummy substrates for impedance correction use are provided and the impedances between electrode plates are corrected so as to become uniform over the whole region of each electrode plate. CONSTITUTION:If there is a gap between substrates 4 and electrode plates 2, different contact resistances and different capacitances are generated according to the flatnesses of the plates 2 and the degree of roughness of the surfaces of the plates 2. Moreover, by the plates 2, variation is generated in the impedances between the upper and lower electrode plates over the whole region of each electrode plate. There, the resistance and capacitance of each dummy electrode 6 are matched to the variation of the impedance of each plate 2 and the impedances between the upper and lower electrode plates can be uniformly matched to each other properly over the whole region of each electrode plate. Thereby, plasma power is uniformly distributed between the plates 2 and a film having a good uniformity can be deposited on each substrate 4. Moreover, the substrates 4 are respectively mounted to the lower part of each plate 2 by fixing jigs 5 and the above effect is fulfilled.

Abstract: PURPOSE: To obtain a magnetic head capable of making a magnetic latent image in a short time and easy to produce by a method wherein electric currents of different directions are applied selectively to each lead wire of a magnetic head and a recording magnetic field is impressed selectively on a magnetic recording material.  
     CONSTITUTION: When a downward current is applied to a lead wire A in the figure and an upward current is applied to a lead wire B in the figure, a magnetic field is concentrated to a main magnetic pole 7 facing a grid zone (a) made up by these lead wires A, B, E, F and a vertical magnetizing membrane portion 10 on this main magnetic pole 7 is magnetized. Then, when a downward current is applied to the lead wire B in the figure, the magnetic field is concentrated to the main magnetic pole 7 facing a zone (b) made up by lead wires B, C, E, F and the vertical magnetizing membrane portion 10 on this main magnetic pole 7 is magnetized. In like manner, when a downward current to a lead wire C in the figure and an upward current to a lead wire D in the figure are applied respectively, the vertical magnetizing membrane portion 10 on the main magnetic pole 7 facing a zone (c) is magnetized. Thus, by applying electric current only to portions requiring magnetization, those portions are magnetized to form magnetic latent images.

Abstract: PURPOSE: To decide a character or a noise and prevent misreading, by checking the amount of a black signal in the scanning area.  
     CONSTITUTION: The fixed value is preset to the counter 29 by the initial data information, a mode signal and a load signal, in accordance with the conditions such as whether a period is read as a character or not, etc. A pattern signal obtained by cutting out a character is input to the counter by taking AND with a clock signal. When the counter has overflowed, "1" is provided as an output so that an input to the counter can be stopped by the aforesaid output. In case an output of the counter 29 is "1" at the time point when a pattern signal of the cut-off character has been finished, it is shown that the character is not a noize. In case it is not "1", it is shown that the cut-out character is a noize.

Title: Identification signal recording system for software recording medium
Inventor: DAIGAKU MASAAKI
IPC: G11B20/00
Filed: 1983-07-08
Abstract: PURPOSE:To eliminate the adverse effect due to an identification signal at the use of a tape by recording the 2nd identification signal having a frequency, an amplitude and a phase to be cancelled substantially when the signal is synthesized with the 1st identification signal at the reproduction of a soft-ware recording medium. CONSTITUTION:A signal Ea recorded on a region Ta and a signal Eb recorded on a region Tb have the same frequency and the same amplitude but an opposite phase. On the other hand, a signal Ec recorded on a region Tc and a signal Ed recorded on a region Td have the same frequency, amplitude and phase. In reproducing the software tape recorded in this way by a 2-channel stereo phonic head, the signal waveform output is obtained as it is but in reproducing the soft- ware tape as shown in Fig. by a monaural head, or the signals obtained through the reproduction of the 2-channel stereo phonic head are synthesized, then the signals Ea and Eb are cancelled together and the resulting level is 0 and no signal is outputted. Further, since the signals Ec and Ed have the same frequency and same phase, a signal having a double amplitude is obtained.
