Title: Method for foreseeing abnormality in horizontal and continuous casting plant
Inventor: IIDA SHINZOU
IPC: B22D11/16
Filed: 1980-12-10
Abstract: PURPOSE: To foresee abnormality such as shell breakout and clogging and the cause for the same and make operation stable by embedding temp. detectors in the inlet part of a mold and monitoring the fluctuations of the output signals thereof.  
     CONSTITUTION: The detection of clogging is accomplished by utilizing the time average of the detection signals of the 1stW3rd temp. detectors 6W8 having increased differences in temp. from the normal time out of the 1stW4th temp. detectors 6W9. On the other hand, in case when no shells are formed in the inlet part of a mold 3, hence the so-called shell breakdown that the molten metal contacts the inside wall 3a of the mold directly takes place, the temp. detected with the 2nd temp. detector 7 produces sinusoidal oscillations in correspondence to drawing cycles, and further double peaks are generated in the oscillation of the temp. detected with the 3rd temp. detector 8 and the temp. detected with the 4th temp. detector 9 goes much higher as compared to the temp. detected in the normal time. Hence, the generation of the shell breakdown is detected by detecting the above-mentioned characteristics.

Title: Number plate character segmenting device
Inventor: SHIMIZU SANAE
IPC: G06K9/34
Filed: 1991-07-16
Abstract: PURPOSE:To segment the character area of a number plate out of a photographed image. CONSTITUTION:The image of a car which is photographed by a camera 1 is once stored in an image memory 2 and then replaced with a binary image by a binarization processing circuit 3. The binary image is divided by an area dividing circuit 4 and the character area candidate equal to a prescribed frame is extracted by a character area candidate extracting circuit 5. Then a positional relation detecting circuit 6 detects the relation of the characters peripheral to the extracted character area candidate. A character area selecting circuit 7 selects the relation coincident to the character positional relation of a number plate. Thus the character area of the number plate is segmented.

Title: Schmitt circuit
Inventor: YOKOYAMA RYOICHI
IPC: H03K3/2897
Filed: 1985-08-08
Abstract: PURPOSE:To facilitate the determination of hysteresis characteristics and to stabilize characteristics of components by employing a differential amplification mode. CONSTITUTION:When an input voltage impressed to an input terminal 11 is much lower than the voltage of E16, QN1 is off and QN2 is on; and the base current of QP3 and a current from R7 flow in the collector of the QN2 and QP3 is at a low level. In this case, input/output characteristics are hysteresis characteristics symmetrical about the voltage e1 of the E16 and the hysteresis width is widened by increasing a resistance value or a constant current value. When only Rs 7 and 8 increase in resistance value owing to variance, the hysteresis width increased, but the resistance value of R52 also increases when a Schmitt circuit is composed of an integrated circuit, so the constant current value of I05 decreases and the hysteresis width is held constant regardless of variance in resistance value.

Abstract: PURPOSE:To improve remarkably the picture accuracy of a solid-state image pickup device by providing a means for shifting bits of a picture element signal data to the input side of a sensitivity correction operating section and a sensitivity correction function section to correct each picture element signal with high accuracy. CONSTITUTION:Bit shifters 15a, 15b are added to an input section of a microprocessor 13 and a bit shifter 15c is added to the input side of a multiplier 16 to attain external bit shift to data.

Since the over-range of the correction data is prevented regardless of the quantity of the output data from a solid-state image pickup element 1, each picture element signal is corrected with high accuracy.

Title: Semiconductor neutron beam detector
Inventor: SATO NORITADA
IPC: H01L31/09
Filed: 1988-07-15
Abstract: PURPOSE:To effectively utilize generated alpha-ray or <7>Li nuclei to generate electron-hole pairs by reducing the thickness of a boron film containing concentrated isotope <10>B on an N-type semiconductor substrate thinner than the pass length in the boron film of the alpha-ray. CONSTITUTION:An N-type semiconductor substrate 21 is covered with a boron film 22 containing concentrated isotope <10>B. In a neutron beam detector having a P-type doping layer 23a under the film 22, the thickness of the film 22 is thinner than the pass length in the boron film of the alpha-ray. The pass length of the alpha-ray in the film 22 is approx. 4.4mum, the pass length of <7>Li nuclei is approx. 1.4mum extremely short. Accordingly, if the film 22 is excessively thick, the alpha-ray and <7>Li nuclei generated near the surface of the boron film are merely absorbed into the boron film, and not arrived at a depleted layer 27. Then, if the thickness of the boron film is longer than the case of the <7>Li and thinner than the pass length of the boron film of the alpha longer than the case of the <7>Li nuclei, almost all of the alpha-ray flying at least to a depleted layer side contribute to the generation of electron-hole pairs, thereby improving neutron beam sensitivity.
