Title: Character array detecting device
Inventor: ITEZONO TOSHIYUKI
IPC: G06K9/20
Filed: 1988-02-22
Abstract: PURPOSE:To make it unnecessary to prepare a histogram and to simplify a device constitution by detecting the starting edge position and termination position of an array based on the detecting signal of a first picture element and a second picture element on a scanning line. CONSTITUTION:The picture data from a reader 22 are inputted through a picture memory 24 to a character array detecting device 24. When a character line detecting means 12 detects the first picture element on the scanning line of a scanning range, a first detecting signal to show the detection is preserved, and when a second picture element only is detected in the scanning line of the scanning range, a second detecting signal to show the detection is preserved. A character array detecting control means 14 detects the starting edge position and the termination position of the array based on these first and second detecting signals.

Title: Binarizing processing system in picture reader
Inventor: YAMAZAKI NOBUHISA
IPC: H04N1/401
Filed: 1989-02-20
Abstract: PURPOSE:To quicken the picture reading and to prevent the deterioration in the picture quality by detecting a white level peak value for each raster during original reading, generating a slice level from the peak value, applying binarizing or dither processing and following up the control to a change in the light quantity, background color and picture characteristic. CONSTITUTION:A white level reference board is placed also to the left side of an original together with the head of the original and each raster scans an original face after the scanning of the left side white level reference plate. When the white level reference board at the head of the original is subjected to raster scanning, a shading correction circuit 6 stores a white level data by one raster into a RAM 61. The white level reference board at the left side of the original is read, a peak hold circuit 71 detects a white peak level W and reads it in an MPU 73. The MPU 73 generates a slice level of W/2 and applies it to one input of a binarizing circuit 9. A slice level W'/2 based on the white peak level W' is used when the read of the background area is finished to read the character area. When the character area is switched into a photographic area, the MPU 73 changes the slice level into W/2 to apply reading.

IPC: H01L41/18
Filed: 1988-02-24
Abstract: PURPOSE:To suppress the maximal firing temperature low by making a specific amount of at least one kind of a specific lead composite perovskite to be added as an auxiliary component to the main component while constituting the main component of Pb(Mg1/3Nb2/3)O3-PbTiO3-PbZrO3. CONSTITUTION:When the main component is expressed as [Pb(Mg1/3Nb2/3)O3]x [PbTiO3]y [PbZrO3]z, a main component constituting range is limited to the values, which are 0.10<=x<=0.60, 0.30<=y<=0.60, 0.10<=z<=0.60 (x+y+z=1). When 0.01 to 20mol% of lead composite perovskite Pb(Ni1/2W1/2)O3 or the like added to the main component, the optimal firing temperature sharply drops, while increasing mechanical strength, further being able to enlarge epsilon /epsilon0 without lowering kp. When the contents of Pb(Ni1/2W1/2)O3 or the like are less than 0.01mol% to the main component, efficiency of improving a characteristic is little and when the contents exceed 20mol%, kp drops remarkably.
