Patent JP-H01300572-A (JP)
Title: Optically driven semiconductor device
Inventor: TAKEHARA KATSUNAO
IPC: H04N5/335
Filed: 1988-05-27
Abstract: PURPOSE:To obviate the need of attaching an optical filter to the outside of a device for actuating the device by a specific wavelength of light by arranging filters in a light-transmitting section. CONSTITUTION:A white regulating semiconductor device is provided with three light-transmitting plates having different properties, consisting of a light diffusing plate 13, an ultraviolet cutoff plate 12 and an infrared cutoff plate 11. Since the infrared cutoff plate generally has the lowest moisture resistance among the three, it is arranged in the innermost place within the semiconductor device. Thereby, the semiconductor device has all the functions for regulating white by itself. In this manner, it is possible to obtain an optically driven semiconductor device having properties to various wavelengths of light by suitably selecting filters attached thereto, without requiring any optical filter attached to the outside of the device.

Filed: 1984-06-25
Abstract: PURPOSE:To discriminate easily a through hole part from a light transmitting part at a base area of a printed board, by cutting only the peripheral part of a large pattern of the light leakage pattern signals. CONSTITUTION:A printed board 1 is exposed in the illumination beams 2 and at the same time shifted to the right from the left at a fixed speed. When a through hole reaches at a point (a) where nothing exist to shield the light at the illumination side, a signal is detected by a CCD5 via a lens 4.

Then the through hole reaches a point (a') where a light shielding mask 3 is put after a fixed period of time, a through hole image is formed on a CCD6 through the lens 4. If the through hole plated area has a defect, the light is irradiated inside the through hole through the defective area. This leakage light is detected by the CCD6, and this detection signal is binary coded by a binary coding circuit 8. Then only the peripheral part of a large light leakage pattern is cut by a filter circuit 10.

Scattered light reflected by the manuscript is transmitted through the layer 12 to the opposite direction and is made incident on the layer 14. A photocurrent can be led out through the layers 16 and 12 having a conductivity. When the beam is made to scan along the holes 18, light is irradiated in order on each point, which corresponds to each through hole 18, on the manuscript. Photocurrents to correspond to the lightness and darkness of each point on the paper are led out in order through the layers 16 and 12. Thereby, the manufacture of a contact type image sensor is facilitated and the production cost is significantly reduced.
