Title: Luminance/chrominance signal separation circuit
Inventor: FUJII TOSHIKAZU
IPC: H04N9/78
Filed: 1988-12-28
Abstract: PURPOSE:To perform the separation of a luminance signal with few dot disturbance and with high resolution from a chrominance signal by varying the area of a non-correlative component corresponding to the state of a composite video signal. CONSTITUTION:The characteristic of a chrominance signal elimination filter E with variable characteristic is varied by a control signal from a control signal generation circuit F which generates the control signal representing the level of a luminance signal component based on the output of a subtraction circuit C. When the high correlation of the composite video signal exists, the characteristic of the chrominance signal elimination filter E is switched to the one with large amount of elimination of the chrominance signal by the control signal of low level since a few amount of luminance signal component leaking in a chrominance signal component outputted from the subtraction circuit C. Thereby, an effect to prevent the occurrence of the dot disturbance can be heightened. When the correlation of the composite video signal is weak, the characteristic of the chrominance signal elimination filter E is switched to the one with small amount of elimination of the chrominance signal. Thus, it is possible to weaken the chrominance signal elimination effect of the chrominance signal elimination filter E and to prevent the resolution of the composite video signal with large amount of washboard or oblique information from deteriorating.

Title: Semiconductor device
Inventor: ASANO YUJI
IPC: H01L27/04
Filed: 1989-12-21
Abstract: PURPOSE:To improve the reliability of a semiconductor device as well as to contrive the improvement of the yield of the manufacture of the device by a method wherein a concentration distribution that the concentration of an impurity in a semiconductor film is small in the interface part between an insulating film and the semiconductor film and the concentration becomes the larger the more distant from the interface part is given to the impurity in the semiconductor film. CONSTITUTION:The concentration of an impurity in a semiconductor film is distributed in such a way that the concentration is small in the interface part 15 between an insulating film 17 and the semiconductor film and the concentration becomes the larger the more distant from the part 15. As a result, even if pinholes are generated in the film 17, an upper electrode 18 and the semiconductor film do not form an ohmic contact unlike a conventional method and form a Schottky junction because the impurity concentration in the semiconductor film directly under the film 17 is small. Accordingly, in the case that the semiconductor film is an N-type, if the conductive film is biased to a negative potential like the conventional method and the semiconductor film is biased to a positive one, the Schottky junction is brought into a reverse-biased state. Therefore, a leakage current does never flow via the pinholes. Thereby, the reliability of a semiconductor device is improved and at the same time, the yield of the manufacture of the device is enhanced.

Title: Printed wiring board
Inventor: KITAICHI TATSUHIRO
IPC: H05K3/34
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To prevent short circuits of solder at the time of soldering by forming a barrier wall of marking ink for preventing flow-out of solder on a resist, thereby preventing flow-out of solder to a neighboring small diameter VIA or a pad. SOLUTION: In a printed wiring board 10 provided with small diameter VIAs 4 and pads 5 at a specified pitch, a barrier wall 1 for preventing flow-out of solder is formed of a marking ink 3 on a resist 2. Since the barrier wall 1 prevents a solder to be soldered to a specified position from flowing out to a neighboring small diameter VIA 4 or a pad 5, short circuit of solder is prevented at the time of soldering. The barrier wall 1 is formed by simply setting a marking position in addition to marking process, without requiring additional processes. Solder short circuiting between the pad 5 and the small diameter VIAs 4 or among the small diameter VIAs can also be prevented, when the barrier wall 1 is formed on the small diameter VIAs 4.
