Title: Tv signal processing circuit
Inventor: ISONO KATSUO
IPC: H04N7/01
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To effectively eliminate white longitudinal lines at both ends of a screen by giving a horizontal sharpness blanking signal to a sharpness control terminal for a non-signal period including both left/right ends of the screen in normal display of a television receiver with a laterally long screen. SOLUTION: One input of an OR gate 281 of a sharpness blanking generating circuit 280 receives a luminance signal YS from an aspect ratio conversion circuit 220 and the other input receives a luminance signal YS from a PIP circuit 230 to display a slave pattern in a master pattern. A time constant circuit consisting of a resistor 283 and a capacitor 284 of the buffer 280 delays an output leading edge but does not delay a tailing edge. An output waveform (i) is fed to a sharpness terminal T via a position B of a changeover switch SW via a transistor(TR) 287 deciding a high level output and a buffer 285. As a result, a quadratic differentiation waveform at both ends of the screen in a luminance output signal is eliminated and undesired longitudinal lines at both ends of the screen are eliminated while keeping a sharp effect on the screen except both the ends.

IPC: H01L21/31
Filed: 1986-09-09
Abstract: PURPOSE:To provide a mask sputtering method which can yield exact films corresponding to a pattern even if the formed films have a large thickness, by using a mask formed by superposing >=2 sheets of mask materials having the through-holes of approximately the same pattern, thereby preventing the camber of the mask. CONSTITUTION:The mask material 1 having; for example, a circular shape has the plural slit-like through-holes 2 as shown in the figure. Two sheets of the mask materials 1 are superposed in such a manner that the mutual through- holes 2 are superposed on each other as shown in the figure (a). Such material is disposed as the mask material 10 on a thin film forming surface 3a on a substrate 3. A film material is then sputtered from below onto the substrate 3 disposed with the mask 10 to stick the film material only to the part of the thin film forming surface 3a superposed with the through-holes 2, by which the thin films corresponding to the pattern of the through-holes 2 are formed. Since the mask material 10 consists of two sheets of the mask materials 1, the upper mask material is in close contact with the substrate 3 even if the lower mask material 1 cambers as shown in the figure (b); therefore, the thin films corresponding to the prescribed pattern are exactly formed.

IPC: B41J2/36
Filed: 1990-08-10
Abstract: PURPOSE:To make sizes of dots identical in recording before and after one-time stoppage of the recording operation on restarting of the recording operation by a method wherein recording energy to be applied on the restarting of the operation for the recording of a new line is made bigger than that applied for the recording operation continuously carried out from the preceding line to the new line. CONSTITUTION:When a command is given for recording of a new line on one- time stoppage of the recording operation after finishing of the recording for a preceding line, a signal is sent from a pulse control section 30 to a pulse generating circuit 28 so that recording energy which is bigger than that applied when the recording is made successively from the preceding line to the new lime can be applied. Then the recording operation starts with bigger energy through a thermal head 14 for the new line on thermosensitve paper. Therefore sizes of recording dots on the preceding line (Ln) and the sizes of the dots on the new line (Ln+1) become almost identical, and continuity of the dots in the recording before and after the one-time stoppage is secured smoothly, preventing discontinuity from occurring to recorded images or the like.
