Abstract: PURPOSE:To improve the hot hardness of a steel, by using, as starting raw materials, respective pulverized powders, as raw materials, of metals as simple substances, carbides, etc., for producing a steel with a specific composition and by subjecting the above to pressing and heat treatment under respectively prescribed conditions. CONSTITUTION:Pulverized powders as raw materials (powders of Fe, Cr, and Mn, powders of the carbides of Cr, V, Nb, and Ti, graphite powder, etc.) for producing a steel having a composition consisting of 0.65-1.40% C, 10.00-20.00% Mn, one or more kinds (2.00-6.00%, in total, of two or more kinds) among 7.00-15.00% Cr, 2.00-6.00% V, 2.00-6.00% Nb, and 1.80-5.00% Ti, and the balance iron with usual impurities as powdery starting raw materials.

Title: Leader tape for magnetic tape
Inventor: USHIMARU AKIRA
IPC: G11B5/627
Filed: 1984-09-17
Abstract: PURPOSE:To attain excellence in prevention of any of increase in dropout, scratch, loss of adhesion, transfer, clamp copy, and exfoliation of tape by containing conductive powder and binder and forming a coating layer made mainly of tin oxide and specifying light transmittivity, surface coarseness and total thickness. CONSTITUTION:In forming a coating layer with conductive powder made mainly of tin oxide while being scattered in a binder, the layer had a high conductivity and >=20% of light transmittivity. The transfer of the ruggedness of the surface of a leader tape onto a magnetic recording layer of the magnetic tape is prevented by designing the surface coarseness of the leader tape as 0.020-0.045mum. Further, the total thickness of the leader tape is specified as 15-38mum, this is because too thick tape causes ease of exfoliation when the tape is bonded with a splicing tape and too thin tape causes ease of transfer of clamp copy of a winding core to a recording layer of the magnetic tape when the magnetic tape is wound on the winding core.

Abstract: PURPOSE:To obtain a porous membrane prevented from the generation of wrinkles or deformation at the time of coagulation and useful as the support of a functional membrane in a dry state, by reinforcing a polysulfone porous membrane having dense layers on both surfaces thereof by a fibrous support to form a composite membrane. CONSTITUTION:Polysulfone is dissolved in a polar solvent such as N- methylpyrrolidone to adjust the viscosity of the obtained solution to 2-500 poise. This solution is applied to the single surface of a sheet like fibrous support with water permeability of 0.01g/cm<2> or more comprising a polyethylene terephthalate fabric or nonwoven fabric and the coated support is immediately immersed in water and coagulated from both surfaces thereof.

Title: Binarizing device
Inventor: TOYAMA KOICHI
IPC: G06K9/38
Filed: 1989-07-27
Abstract: PURPOSE:To turn an unclear picture into a clear one by preparing plural deciding means and binarizing the picture after deciding whether a noted subwindow is equal to a line graphic part or not based on the outputs of those deciding means. CONSTITUTION:A line picture 1 is photographed by an image sensor 2 and converted into a gradation picture by an A/D converter 3. This gradation picture is stored in a frame memory 4 and then read out for each picture element in the same scanning order as the sensor 2. Thus a mobile subwindow is formed by a 2-dimensional local memory 5. Then a local averaging part 6 calculates the average density value Aij and stores this value in an average density value memory 12 for the local area of a noted picture element. Then a threshold value detecting part 7 calculates the density difference between the noted picture element and a nearby picture element and checks whether this difference is kept within a range of the set value or not. If so, the average value is obtained among all picture elements and defined as the threshold value PA. This value PA is compared with the allowable density difference G0 via a comparator 10. When the value PA is smaller than the difference G0, the even density is secured among local areas. Thus a clear binarized picture is obtained.

Title: Picture display device
Inventor: UEDA MINORU
IPC: G09G3/20
Filed: 1982-11-01
Abstract: PURPOSE:To display an excellent picture free of the influence of mechanical vibration by switching linear cathodes alternately and driving them with pulses, and adjusting heating currents to the linear cathodes, cathode by cathode. CONSTITUTION:This describes an example of a circuit used for optional one of linear cathodes 2a-2o. Transistors (TR) 47a-47o turn on in low-level periods of vertical driving pulses, i.e. in heating periods, and the linear cathodes 2a-2o are heated by a current I1 from a power source +B1 to hold the linear cathodes 2a-2o at positive potentials, so no electron beam is emitted. When the pulses (a-o) are at high levels, a negative power source -B2 is applied to the linear cathodes 2a-2o through TRs 48a-48o to turn of diodes 50a-50o. Consequently, the linear cathodes 2a-2o are held at low potentials to emit electrons with a uniform distribution, and heating currents to the linear cathodes 2a-2o are adjusted individually by variable resistors 57a-57o.

IPC: F16B25/10
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To efficiently fix a gypsum board to a thin steel plate with drilling screws by means of an impact type pneumatic-drive thread fastening machine. SOLUTION: A drilling screw is driven into a gypsum board 2 by means of the driver of an impact type pneumatic-drive thread fastening machine for its taper bit part 16 to bore a hole on a C-shaped steel plate structure 1, and then, a small diameter threaded part 15 pierces the structure 1 to step.
