Title: Electrophotographic method
Inventor: NISHINO TOSHIO
IPC: G03G5/08
Filed: 1986-01-30
Abstract: PURPOSE:To increase the potential contrast on the surface of a photosensitive body by charging electrostatically the entire surface of the photosensitive body after primary electrostatic charging and image exposure at a voltage lower than a primary charging voltage within a time wherein a light parts on the photosensitive body have optical fatigue. CONSTITUTION:A charger 15 for the secondary electrostatic charging is arranged between an optical system 6 and a developing mechanism 8 which are arranged at the periphery of a drum to perform the primary charging and image exposure and the entire surface of an amorphous silicon photoconductor layer 2 where an electrostatic latent image is formed is charged electrostatically and secondarily. This entire-surface secondary charging is carried out without exceeding the primary charging voltage within the time wherein light parts of the photoconductor layer still have optical fatigue. Consequently, the electrophotographic method which uses the amorphous silicon photosensitive body increases the potential contrast on the surface of the photosensitive body without any increase in the film thickness of the photoconductor layer.

Title: Electronic blackboard device
Inventor: SUGA YUKIO
IPC: B43L1/04
Filed: 1993-01-08
Abstract: PURPOSE:To obtain an electronic blackboard device, with multiple writable facets where data can be written and erased, of an endless sheet structure having, at least, a single reversibly foldable area in parallel with the writable facet of a writing medium of a writable/erasable material. CONSTITUTION:If it is necessary to check an image of written data again or write additional data, an endless sheet 25 is moved reversibly or normally and stopped so that additional data is written or already written data is corrected. After that, data is printed by the same procedures. Part of the endless sheet 25 is folded starting from a roller 28 as a starting point behind the writable facet, and is positioned almost in parallel with the writable facet as a reversibly folded area. Thus the number of image-bearing facets of the endless sheet 25 is increased. Consequently, it is possible to provide the increased number of image-bearing facets and select any other writable facet in a short time.

Abstract: PROBLEM TO BE SOLVED: To specify a failure part by measuring the surface temperature distribution of a specimen in an operating state. SOLUTION: A temperature sensor 7, e.g. an infrared image sensor, can measure a surface temperature 120 as a plane image in which the object part as a whole of a specimen 1 can be surveyed. The temperature distribution of the specimen 1 as an object to be measured is measured by the temperature sensor 7, it is converted into surface-temperature-distribution data (an electric signal) 102 in the form of a prescribed signal, e.g. the electric signal. The data (the electric signal) 102 is converted into surface-temperature-distribution data (a voltage) 104 corresponding to the temperature by a temperature detection circuit 8. The data (the voltage) 104 is converted into surface-temperature- distribution data (digital data) 106 by an A/D conversion circuit 9.  The digital data 106 is converted into data 108, for display, by an image processing circuit 101 so as to be displayed on a display 6. Thereby, it is possible to use another physical phenomenon as the surface temperature of the specimen 1.

Title: Memory device for pointer-type data
Inventor: TAKEUCHI SHIYOUICHI
IPC: G06F5/06
Filed: 1980-02-14
Abstract: PURPOSE:To realize a more effective process of the data row and then increase the speed of process with a low cost, by dividing a memory device into the contents part and the pointer part and at the same time using an element having a higher access time to the pointer part than the contents part. CONSTITUTION:The values of both the pointer and contents parts are read out to the memory buffers 2a and 2b by the memory devices 1a and 1b each and based on the address set to the memory address register 3. A difference is caused to the read- out time between the two values by the difference of the access time, and thus the pointer part is read out earlier than the contents part. The value of the pointer part read out earlier is set to the register 3 for reading of the next data, and then the value of the contents part is extracted out of the memory buffer 2b to complete the reading procedure of a data. After this, the reading of the next data starts.

Title: Method for manufacturing cathode ray tube
Inventor: YAMAMOTO SUMIO
IPC: H01J9/44
Filed: 1983-02-03
Abstract: PURPOSE:To provide a stable beam drift, by keeping the cathode member, after the same has been subjected to the activation treatment, and the control electrode member at the same potential, and setting the anode member at the high tension corresponding to the anode voltage, and thereby allowing for the emission of the electrons at the amount corresponding to the maximum emission for the period of at least 5 seconds. CONSTITUTION:The cathode member K, after the same has been subjected to the activation treatment, and the control electrode member G1 are kept at the same potential, the accelerating electrode member at 300-400V, the focusing electrode member G3 at 4-5kV, and the anode member at 20-25kV, and the so-called maximum emission is allowed for at least for the period of time of 5sec. Since the electron beam corresponding to 3mA flows from the cathode member K by this treatment, the uneven potential gradient at the neck portion 1a is brought to a stable state in a short period of time by the so-called shower effect, i.e., the effect that the high tension of the anode member is induced at the neck portion 1a being induced by the electron beam in a short period of time.

IPC: F04D19/04
Filed: 1990-01-26
Abstract: PURPOSE:To raise the extent of back pressure by way of generating a turbulent flow in gas inside the thread groove of a static cylinder by installing a lot of limited large recesses on both outer and inner circumferential surfaces of a rotary cylinder. CONSTITUTION:A lot of recess train belts 10 and smooth surface belts 14 are installed on the outer circumferential surface of a rotary cylinder 14 alternately in the axial direction, while other lots of recess train belts 12 and smooth surface belts 13 are installed on the inner circumferential surface alternately in the axial direction as well. When the rotary cylinder is rotated, gas inhaled out of an inlet port 19 is compressed downward by a thread groove 1 on the inner circumferential surface of a static cylinder 3 and then it advances upward along a thread groove 4 on the outer circumferential surface of a static inner cylinder 9 and exhausted out of a discharge port 20 after passing through an exhaust hole 6. In proportion as coming closet to this discharge port 20, pressure becomes high whereby a leak out of clearances 17, 18 with the rotary cylinder 14 becomes increased, but it is checked by the smooth surface belts 11, 13, while a turbulent flow is generated in these thread grooves 1, 4 owing to the recess train belts 10, 12. Therefore, each gas flow rate in these thread grooves 1, 4 is increased so that the leak is compensated and, what is more, back pressure can be heightened as well.

Filed: 1993-02-04
Abstract: PURPOSE:To generate the R, G and B components of a luminance signal component and two types of color difference components through a set of addres of plural stages and furthermore to reduce the scale of a digital video encoder circuit with addition of those R, G and components. CONSTITUTION:A 1st adder means 11 calculates the R, G and B components (Y)R, (Y)G and (Y)B of the luminance signal component EY from the input R, G and B signals and also calculates the color difference signal component, etc. These calculated components are supplied to a 2nd adder means 12 which adds together the components (Y)R, (Y)G and (Y)B to calculate the component EY, etc. A modulator means 13 applies the balanced modulation to the chominance subcarriers with phases difference of 90 deg. and outputs these carrier chrominance signal components to a 3rd adder means 14. The means 14 adds each carrier chrominance signal component to the component EY and acquires a video signal EV. This signal EV is converted into an analog video signal by a D/A converter 15 and transmitted. Thus various coloring ways are ensured by combinations of adders and without using the large scale circuits of a multiplier and a divider.

Title: Monocoque construction type reinforcing element for composite structure member of steel and concrete
Inventor: HERUMAN BUEE FUERUTOHORUSUTO
IPC: E04B5/40
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To improve the composite strength of a buried steel mold provided with a deformed cross section on its side face and/or covered surface for improving the degree of bond by forming the cross section of the mold to the deformed cross section closely to the shape of the supporting line. SOLUTION: Since the curved part 5 of a reinforcing element 1 follows the supporting line, the section 5 perpendicularly acts on the surface of the element 1. A driven force generated by the shearing stress of, for example, the area of a knot 8 only generates a normal stress in the element 1. When the force tends to weaken the bond between the element 1 and concrete 9, the normal stress in the element 1 must have such a magnitude that the element 1 is deformed plastically as a result of upsetting. These forces are many times stronger than the bending force which occurs when the cross section has a flat surface. When the cross section has a flat surface, in addition, the avoidance resistance increases due to the supporting line-like cross section and the best bonding behavior is obtained by the combination of knots 8 uniformly distributed in the periphery. Therefore, the composite behavior can be improved and, at the same time, the cost can be reduced.
