Title: Visual sensor device
Inventor: SHIYAKUSHI TETSUO
IPC: G06K7/10
Filed: 1988-10-12
Abstract: PURPOSE:To detect the distance and the tilt against the surface of a detecting subject as well as a mark with high accuracy by changing the light quantity to the surface of the detecting surface in accordance with the detecting subject and at the same time changing the shutter speed of a black/white TV camera. CONSTITUTION:When the distance and the tilt are detected against a subject surface 3, the surface 3 is irradiated with a light beam 2 of a large light quantity so as to prevent the influence of a mark 8. At the same time, the shutter speed of a black/white TV camera 4 is increased so as to prevent the overexposure. When the mark 8 is detected, the mark 8 is illuminated by an auxiliary illuminator 5 as necessary for improvement of a contrast between the mark 8 and its ground color. Under such conditions, the shutter speed of the camera 4 is slowed down to photograph the mark 8. In such a way, the light quantity is changed to the surface 3 and at the same time the shutter speed of the camera 4 is changed. Thus it is possible to detect the distance and the tilt against the surface 3 as well as the mark 8 with high accuracy regardless of the influence of the mark 8 drawn on the surface 3.

Abstract: PURPOSE:To solve the drop in a color resolution in the vertical direction and color run in the vertical direction by giving a comb-line filter characteristic only to a band in the high frequency band of a luminance signal for entering the lower frequency band of a carrier chrominance signal. CONSTITUTION:A color video signal (figure (a) shows the frequency spectrum of an input signal) impressed to an input terminal 1 at recording is inputted to a 1H delay line 2. The luminance signal of the color video signal passing through said 1H delay line 2 delays by 1H, however it has the same phase as a signal before an input in terms of a phase, and the phase of the carrier chrominance signal is inverted. This signal is passed through a low-pass filter 3 having a frequency characteristic as shown in figure (b). The low-pass filter 3 limits the frequency characteristic so that the signal can pass through the frequency band including the high frequency band of the luminance signal for expanding to the lower frequency band of the carrier chrominance signal. The output of the low-pass filter 3 is subtracted from an original signal from the input terminal 1 in a subtractor circuit 4, and a desired carrier chrominance signal can be obtained at an output terminal 5. Figures (c) and (d) show the comb-shaped characteristic of the color comb-shaped filter with the constitution and the frequency spectrum of the desired carrier chrominance signal, respectively.

Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a synchronous embossed decorative sheet rich in a three- dimensional feeling sharply synchronous with a pattern layer and hardly forming a scratch, and a method for producing the same. SOLUTION: A colored solid layer 2 is formed on a base material sheet 1 and, subsequently, patterns are partially printed on the colored solid printing layer 2 to form pattern layers 3. Next, ink having liquid repellency to ionizing radiation curable paint is applied to the surfaces other than the pattern layers 3 by reverse plate printing to form liquid repelling layers 4. Subsequently, ink non-repellent to the ionizing radiation curable paint is printed only on the pattern layers 3 to provide omitted printing layers 5. Next, the surface of the base material sheet passed through the respective processes is coated with the ionizing radiation curable paint and the coated sheet is irradiated with ionizing radiation to form topcoat layers 6.  The topcoat layers 6 on the omitted printing layers 5 are cured so as to be held in the thickness thereof while the topcoat layers 6 on the liquid repelling layers 4 become thin and the topcoat layers 6 on the respective layer can take height difference because of the film thickness of the omitted printing layer 5 and, therefore, the topcoat layers 6 become unevenness sharply synchronous to patterns and are excellent in scratch resistance.
