Filed: 1983-10-24
Abstract: PURPOSE:To prevent circuit disconnection for a long period of time by driving a timer circuit with an alarm signal given from a voltage monitor circuit, at the same time counting the short-circuit frequencies and inhibiting the short-circuit when the count value of short-circuits reaches a prescribed level. CONSTITUTION:When a circuit breaker 2 is turned off by the surge voltage, etc., a voltage monitor circuit 9 detects a drop of the output voltage 102 given from a stabilized power supply circuit 3. An alarm signal 103 is applied to a drive circuit 10 of a relay 8 from the circuit 9, and therefore a contact 81 of the relay 8 is turned on. Then an earth signal 105 is sent to a timer circuit 7. This circuit 7 drives a relay 5 when the time T1 has passed and turns on a relay contact 51 set in parallel to the breaker 2. At the same time, the time counting is also started. Thus the circuit 9 detects the normal voltage, and the contact 51 is kept closed even after the signal 103 is delivered during the OFF time T2 of the relay 8. For this purpose, the relay 5 is controlled. Furthermore, the normal voltage is also supplied to a counter circuit 6 to count the short-circuit frequencies. When the count value of the counter 6 reaches a prescribed level, the drive of the relay 5 is stopped.

IPC: G06T1/00
Filed: 1991-05-09
Abstract: PURPOSE:To achieve a simplification of the measurement of a three-dimensional surface nature and a higher measuring accuracy by projecting reflected and scattered light of a laser beam to perform a two-dimensional measuring processing of the scattered light by an image processing of an image. CONSTITUTION:A laser light generated by a laser light source 1 is adjusted to a fixed intensity with a deflection filter 2 and is made to project on the surface 3 of metal at a fixed angle of incidence. The laser scattered light reflected on a surface 3 is projected onto a semi-permeable screen 4 to be caught as one image with a CCD camera 5 from the side or rear side of the screen. The image is transferred to a computer 7 with an image processor 6 to be stored in the computer as a two-dimensional integral array, which allows a two-dimensional image measuring processing of the scattered light. Thus, the surface nature is determined by performing a two-dimensional image measurement of an image on the screen of the laser scattered light from the surface of the material. This also enables the measurement of a three-dimensional surface nature from an image data to be carried out.

Abstract: PURPOSE:To execute the write/read processing of data without lowering performance by storing the data, which are written into a correspondent block, to a non-volatile memory and writing the data from the non-volatile memory to the alternative area of an array disk device during the idle time of the disk device. CONSTITUTION:When there is no defective block on the recording surfaces of disk devices 1-1 to 1-n, the data are written into the disk devices 1-1 to 1-n and when there are the defective blocks on the recording surfaces of the disk devices 1-1 to 1-n, the data to be written into these defective blocks are stored in non-volatile memories 4-1 to 4-n. Then, the data stored in the non-volatile memories 4-1 to 4-n are written into the alternative areas of the defective blocks during the idle time of the array disk device. Accordingly, even when the data are written into the array disk device and the defective blocks are existent on the recording surfaces of the disk devices 1-1 to 1-n, time delay can be prevented from being generated by the move of a recording head to the alternative area of the defective block during normal working. Thus, the write/read control of the data can be executed without lowering the performance of the device.

A 300 to 1000 Angstrom  level of an undoped epitaxial layer is selectively formed only on the region designed for charge implantation or discharge promptly. The undoped epitaxial layer is forced to incorporate N type impurities even in the epitaxial layer by auto-doping from a base N type impurity layer during growth, which makes it possible to supply electrons. The epitaxial layer is good for the doped epitaxial growth as well. Then, a tunnel oxide film 3 is formed. The tunnel oxide film is formed into epitaxial growth having lower impurity concentration. This construction makes it possible to improve the service life of the tunnel oxide film with dramatic efficiency.

IPC: C08F2/00
Filed: 1989-08-01
Abstract: PURPOSE:To prepare a water-absorbing polymer having excellent physical properties at a high productivity and processability by feeding dropwise an aq. soln. of an alpha,beta-unsatd. carboxylic acid (salt) into a polymn. reactor pressurized with an inert gas and polymerizing the acid (salt) while boiling is prevented. CONSTITUTION:An aq. soln. of a monomer mainly comprising an alpha,beta-unsatd. carboxylic acid (salt) [e.g. (meth)acrylic acid or sodium salt thereof] is fed dropwise into a polymn. reactor pressurized with an inert gas, and polymerized while boiling of the aq. medium is prevented by the gaseous pressure. Thus, the otherwise essential process of purging oxygen from the monomer with nitrogen can be eliminated, enabling a water-sol. polymer to be prepd. at a high productivity and processability. The resulting polymer, excellent in the absorbence and retention power and having consistent qualities, is useful for hygienic goods, e.g., a sanitary good and a diaper and agricultural goods, e.g., a water retentive agent as well as for a flocculant for sludge, a dew condensation preventive for building and a denydrating agent for oils.

Title: Dry/moisture moisture detection system of object surface in which two cameras of same visual field are used
Inventor: OSHIO MAKOTO
IPC: G01N21/21
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To precisely detect the necessary place for water scattering by finding an average value of each pixel of a threshold value subtraction image found by subtracting a threshold value image from a subtraction image obtained by image processing for a pair of horizontal and vertical polarization images taken in by a plurality of cameras, and judging dryness and moisture of an object. SOLUTION: Reflection light from an object surface by a light source is condensed by a lens 1, and a part of a converted parallel beam is taken in as an image in a first camera 4 through a polarization filter 3 transmitting horizontal oscillating light through a translucent mirror 2. The other part of the horizontal beam is taken in as an image in a second camera 7 through a polarization filter 6 transmitting vertical oscillation light through the translucent mirror 2 and a reflection plate 5. Vertical polarization image is subtracted from a pair of horizontal polarization images with regard to the brightness of the pixel of the same spot to obtain a subtraction image.  If the average value of the brightness of the threshold value subtraction image obtained to subtract a corresponding threshold value image from the subtraction image is smaller than a reference value, water scattering is judged necessary.

IPC: B60Q5/00
Filed: 1992-06-18
Abstract: PURPOSE:To provide double air horns having favorable sound with which a warning can be attained completely by inserting a cylinder tank at a center position of bugles facing each other, storing air in the cylinder tank to be discharged gradually, and forming vibration panels of the bugles of different materials. CONSTITUTION:Single bodies of bugles 2, 2' are formed to be a double horn body, and a cylinder tank 3 is inserted to a center part of the bugle 2. Air introduced from an air cylinder through an air hose is introduced into the cylinder tank 3 through a control switch.

The vibration panels are formed of different materials, or of the same material to echo in compliance with different thicknesses, and sound waves vibrating the vibration panels are blown to the outside from the bugles. Since the cylinder tank 3 is inserted, air stored in the cylinder tank 3 is discharged through the air introducing tube gradually, thereby lingering of the sound is kept continously.
