Title: Memory system for image processing
Inventor: MURATA TAKESHI
IPC: G11C29/00
Filed: 1981-06-30
Abstract: PURPOSE:To make the ECC processing accurate and to pick up a desired sub- arrangement, by taking a specified dot unit as the ECC unit corresponding to an arbitrary sub-arrangement at an image processor and providing an ECC code according to the small section. CONSTITUTION:Corresponding to a sub-arrangement (1Xpq)-dot or (pXq)-dot (e.g., p=4, q=8) processed at an image processor, (1Xq), i.e., 8-dot is taken as the ECC unit and (1X2pq) or (pX2q), i.e., 64-dot is taken as the memory access unit. Data read out from a storage device 7 at reading is latched 8-0-8-7 in this ECC unit and applied to 0,8,16,24,32,40,48,56 bit left circular shift circuit 9. After an ECC processing 10 at each ECC unit at data storage, the sub-arrangement not always matched to the ECC unit boundary is selected 11 for 32-bit's share out of 64-bit. Thus, even if the instructed sub-arrangement does not exist in the ECC unit boundary, the ECC processing can accurately be made.

Title: Ophthalmic apparatus
Inventor: YANO NOBUYUKI
IPC: A61B3/10
Filed: 1994-04-15
Abstract: PURPOSE:To facilitate the alignment with an intraocular region, observation and measurement by boring a hole in the central region of a glass filter absorbing light other than laser beam. CONSTITUTION:Alignment detection optical systems 20a, 20b detect the position of an eye 5 to be examined to align the same with a measuring region to determine the position of the eye 5 to be examined. The intensity of the scattered light from a laser projection optical system 1 is analyzed and the turbidity of the measuring region is measured. In an observation optical system, the cornea reflecting light of alignment light is finely limited by a region cutting light other than laser beam and a visible light.infrared ray pervious region when it passes through a filter 13 and the focal depth thereof becomes large. Therefore, even in such a state that an apparatus optical system is aligned with the measuring region axially displaced from a cornea reflecting bright point, the blur of the alignment light image on the surface of an imaging element is kept low and does not become the obstruction in the observation of the measuring region. Since the laser beam emitted to the intraocular measuring region from the laser beam projection optical system 1 transmits through even the peripheral region of the filter 13, the eye to be examined can be clearly observed.

Title: Method for pattern formation
Inventor: HIRAI MICHIO
IPC: H01L21/302
Filed: 1979-08-13
Abstract: PURPOSE:To obtain a high accuracy pattern by applying resist masks to the metal film on a substrate for wet type photo etching wherein a metal thin film is left and the metal thin film is completely removed by successive dry type photo etching. CONSTITUTION:A Cr film 1 is formed on a transparent glass plate 2 and resist masks 3 are applied. Etching removal is done for the film thickness of about 90% by using etchants. Then, etching removal is made for a residual film 6 by plasma etching and the mask of the CR film will be finished. In this composition, after the CR film is etched with accurate width up to the desired depth by wet type photo etching, photo etching is done by maintaining accurate width by dry type photo  etching. The dry type photo etching differs from the wet type photo etching in that plasma radical will not invade into the interface between the CR film and glass plate. Therefore, the photo etching of side face will not rapidly proceed after the Cr film has completely been etched. Therefore, an accurate pattern will be formed.

Abstract: PROBLEM TO BE SOLVED: To obtain a photoreceptor with a surface protective layer excellent in moisture resistance and environmental resistance with satisfactory controllability and stable quality in a small number of processes by forming a surface protective layer on an amorphous silicon photosensitive layer from a silicon nitride film having a specified hydrogen content. SOLUTION: A layer 2 blocking the injection of electric charges and an amorphous silicon photosensitive layer 3 are sequentially formed on an electrically conductive substrate 1 and a surface protective layer 4 made of a silicon nitride (a-SiN:H) film having <=3×10<22> atoms/cm<3> hydrogen content is formed as the top layer by an ECR-CVD method. Since the hydrogen content of the film is low, the film has superior water resistance and environmental resistance. The hydrogen content of the film is controlled by regulating the flow rate of gaseous SiH4 and the electric power of microwaves when the film is formed by the ECR-CVD method using gaseous SiH4 and N2 as raw materials.

Title: Photoelectric type encoder
Inventor: YOSHIMOTO MASANORI
IPC: G01D5/347
Filed: 1984-05-22
Abstract: PURPOSE:To suppress the change in output of a light receiving element, by arranging a fixed slit and a rotary slit so that light passes them in the order of the fixed slit and the rotary slit. CONSTITUTION:An angle between a shaft 2 and a rotary slit plate 3 is made to be theta. A gap between the rotary slit plate 3 and a fixed slit plate 4 is made to be d1. A gap between the rotary slit plate 3 and a light receiving element 7 is made to be d2. When the shaft 2 is rotated by one turn, the gap d1 changes in the range of d1.(1-rcostheta)-d1.(1+rcostheta). The gap d2 changes in the range of d2.(1-rcostheta)-d2.(1+rcostheta). At this time, d1+d2 is kept constant, and the attenuation rate of light is hardly changed at the sum of the gaps d1+d2. Therefore, the output of the light receiving element 7 becomes approximately constant regardless of the rotary angle, even if the angle theta is deviated from 90 deg..
