IPC: G03H1/02
Filed: 1992-09-22
Abstract: PURPOSE:To decrease the flare light at the time of image reproduction by using a photosensitive material which is previously made lower in the concn. of the photosensitive dyestuff or photoreaction initiator near the surfaces of the photosensitive material than the respective concns. within the photosensitive material. CONSTITUTION:The photosensitive material which is previously made lower in the concn. of the photosensitive dyestuff or photoreaction initiator near at least the one surfaces of the photosensitive material than the concn. within the photosensitive material is subjected to exposing to form prescribed diffraction gratings. The photosensitive material has hologram surfaces 1, 2, the parts 4 of which having a high refractive index and the parts 5 having a low refractive index form the diffraction gratings by their layer structures. The diffraction gratings gradually disappear the nearer the surface 2 from the inside within the transition layer 3 on the surface 2 side. The diffraction gratings do not exist in the extreme surface 2 which has the uniform structure. Light partly transmits the holograms when the light is made incident on the holograms from the surface 1 side, but spurious multislits do not exist on the extreme surface on the surface 2 side and, therefore, there are no diffraction and scattering.

Title: Ultraviolet erasable memory
Inventor: YAMAGUCHI AKIHIRO
IPC: H01L21/8247
Filed: 1986-11-20
Abstract: PURPOSE:To prevent the lowering of the strength of a package, and to improve the area efficiency of a semiconductor chip capable of being sealed into the package by mounting a rectangular window for applying ultraviolet rays. CONSTITUTION:The title memory is constituted of a package 2, an ultraviolet erasable memory chip 1 shaped onto a semiconductor substrate in the package 2 and a square window 3 being positioned onto the package 2, being coated with an ultraviolet transmissible material and having the length of one side of 1.4r. Since a circular window having a radius (r) is formed in place of the square window 3 having the length of one side of 1.4r in conventional devices, the area ratio of the window is reduced. Accordingly, the area of an opening section into which the window of the package is shaped can be made smaller than that of the circular window, the strength of the package can be increased, and a semiconductor chip having a larger area can be irradiated with ultraviolet rays when the area of the window is equalized.

IPC: G06F3/038
Filed: 1991-10-01
Abstract: PURPOSE:To accurately shape the waveform of an output pulse from a photointerrupter without being affected by noise while saving handling time for adjusting the amplitude. CONSTITUTION:An output pulse PS from the photointerrupter is compared with a threshold value SL1 by a comparator 4 and binarized. A comparator 5 generates a gate pulse GP at a level 'H' when the output pulse PS is larger than a threshold value SL2, and during this pulse period, a clock CLK is passed through an AND gate 7 and counted up by a U/D counter 8. The count value of the U/D counter 8 is converted by a D/A converter 9 and turned to the threshold value SL2. The edge of an output pulse PS' from the comparator 4 is detected by an edge detector 6, and an edge pulse EG is counted down by the U/D counter 8. Thus, the peak value of the pulse PS is held in the U/D counter 8. The threshold value SL1 is formed by potential-dividing the threshold value SL2 at a potential divider 10.
