Abstract: PROBLEM TO BE SOLVED: To correct the cross talk of a plasma address display device for enhancing the quality of images. SOLUTION: A plasma address display device is provided with a panel 1 in which a plasma cell and a liquid crystal cell are joined to each other through a dielectric sheet. The plasma cell has discharge channels 5 arranged in rows, and on the other hand, the liquid crystal panel is provided with signal electrodes 4 arranged in columns; and an image plane 6 is constituted by defining image elements 6 in the intersections of the discharge chambers 5 and the signal electrodes 4. A scanning circuit 2 is connected to the discharge channels 5, and the discharge channels 5 are successively discharge-driven all over the image plane for selecting the image elements 6 for each row through the dielectric sheet.  A signal circuit 3 is connected to the signal electrodes 4 so as to drive the signal electrode 4 in synchronization with the discharge drive and also on the basis of the image data for one image plane and to write the signal voltage onto the selected image elements 6. An arithmetic circuit 8 calculates for each row the effective potential difference produced between the adjacent signal electrodes 4 on the basis of the image data that have been input from the outside, and integrates them all over the image plane. A correction circuit 9 corrects the signal voltage to be supplied to the respective signal electrodes 4 on the basis of the result of integration, and reduces the cross talk attributable to the potential difference between adjacent signal electrodes 4.

Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To linearly vary the oscillation frequency of a quartz oscillator by applying DC power voltage of a buffer part to the pressure dividing point of plural first resistors through a second resistor. SOLUTION: For using the part of satisfactory linearity with capacity characteristic against voltage in a barrier cap type diode VC, Vcont is divided and variable voltage width applied to the barrier cap diode VC is narrowed. The resistors R1-R3 are connected in series between the terminal to which DC control voltage Vcont is applied and ground, and the barrier cap diode VC to the resistor R2 in parallel. Capacitors C1 and C2 and a trimmer capacitor CT are connected in parallel between the pressure dividing point (a) and ground. For improving the linearity of the oscillation frequency against Vcont, a resistor R4 is connected to the voltage dividing point (a) and power voltage Vcc to the other end.  When the resistance value of the resistor R4 which is to be connected to two closed circuits is calculated and the obtained value is applied to the circuits, the linearity of the frequency differential characteristic of a quartz oscillation circuit is improved.

IPC: G11B5/85
Filed: 1987-01-28
Abstract: PURPOSE:To permit adjustment of a degree of nitridation in the depth direction of a thin film and to obtain the thin iron nitride film having desired characteristics by projecting ion current in such a manner that the density thereof is larger in the position nearer the min. incident angle of a cylindrical drum in an incident vacuum deposition method. CONSTITUTION:The vapor evaporated from a vapor deposition source 3 when said source is heated flies toward a direction 4 and sticks onto a film 2. The vapor is controlled by an antisticking mask 5 so as to be projected to the film 2 only from the direction diagonal thereto. The vapor is so projected that the angle between the perpendicular rising from the center of the cylindrical drum 1 and the direction 4 of the vapor flow attains the min. angle in the position near the mask 5 and that the density of the ion current is larger nearer said position. The treatment of the ion current essentially consisting of nitrogen is thus executed from the beginning of the vapor deposition of the magnetic material to be deposited by evaporation or the material to form the magnetic material and, therefore, the control of the magnetic characteristics and corrosion resistance of the magnetic layer to be formed is permitted. The magnetic layer having the various magnetic characteristics is thereby obtd.
