A water-in-oil (W/O) emulsion ink for stencil printing is provided which is prevented from pigment aggregation and thus excellent in ink fixability, high in printing density and less declining in printing density even after printing many sheets. The emulsion ink has a ratio by volume of the water phase to liquid components of the oil phase (i.e., volume of water phase/volume of the liquid components of oil phase) in a range of 1.0 to 3.5, preferably 1.0 to 3.0 at 23° C. The liquid components of the oil phase may be composed of a resin, a solvent and a surfactant. The oil phase can contain a pigment at a ratio by volume of 0.19 or less to the total volume of the oil phase. The pigment preferably has an average particle size of 0.02 to 1.5 (&mgr;m). The water phase preferably has an average particle size of 0.1 to 1.0 (&mgr;m). The ink is suitable for containing particles of organic pigments with non-uniform shapes and a large average particle size like copper phthalocyanine blue and diaxazine violet.
摘要:
In a semiconductor device employing a glass substrate, the object of the present invention is to provide a high performance semiconductor device with a large screen at low cost, which prevents the semiconductor device from being contaminated by impurities from the glass substrate. In a semiconductor device comprising a blocking film provided in contact with a glass substrate and TFTs provided on the blocking film, the blocking film is characterized by being made of a tantalum oxide film.

A foreign matter removing mechanism for an electrophotographic printer, which includes: a sheet guide 2a, arranged between a photosensitive drum 1 and a tractor 9, for guiding a print sheet 3; and a foreign matter removing member 5 arranged so as to confront the sheet guide 2a through a predetermined gap 4 relative to the sheet guide 2a. In the foreign matter removing mechanism, a notch 11 is arranged on at least one confronting surface of the sheet guide 2a and the foreign matter removing member 5.
摘要:
An optical data medium is disclosed from which information recorded to the surface is reproduced by focusing a laser thereon and reading the light reflected from the data surface. The medium includes a first transparent layer having a top data surface for carrying data, and a second transparent layer having a bottom data surface for carrying data. A semi-transparent layer is inserted between the first and second transparent layers. When the laser is focused on the top data surface, the data carried therein is reproduced, and when the laser is focused on the bottom data surface, the data carried therein is reproduced.

In a printer control device, the number of documents to be copied and the number of recording sheets on a sheet supplying tray are detected and subjected to comparison, and when the number of recording sheets is smaller than the number of documents, a signal is generated to replenish the tray with recording sheets, whereby if the number of recording sheets on the tray is not sufficient to copy all the documents, the operator is informed of the shortage of recording sheets before the printing operation starts.
摘要:
A high-strength martensitic stainless steel excellent in corrosion resistance and stress corrosion cracking resistance, the composition of which comprises: 0.1% or less carbon, 1% or less silicon, 2% or less manganese, 8-14% chromium, 1.2-4.5% copper, 0.005-0.2% aluminum, 0.01-0.15% nitrogen, and the balance of iron except incidental elements. The stainless steel can contain nickel, molybdenum, tungsten, vanadium, titanium, niobium, etc. under the fixed conditions in addition to the above elements. The heat treatment of the stainless steel comprises: the step of austenitizing at temperatures of 920.degree. C. to 1,000.degree. C., the step of cooling at a cooling rate equal to or higher than the air cooling rate, the step of tempering at temperatures between 580.degree. C. and A.sub.cl point, and the step of cooling at a cooling rate higher than the air cooling rate.
摘要:
A particulate polyolefin molding material is disclosed. The material is comprised of a particulate polyolefin particle having a bulk density of 0.45 g/cc or more and a mean particle size of 150 to 2,000.mu., and a layer comprising a compounding additive and a binder formed on the surface of the particle. The material can be used in producing molded articles without first forming the material into pellets as is conventionally done.
摘要:
An automatic glass plate piling apparatus includes a feeding conveyor for conveying a glass plate in the horizontal direction; a turning frame pivoted at an end of the conveyor so as to receive the glass plate transferred from the conveyor and to turn it at a predetermined angle; a transfer frame disposed below the turning frame to receive the glass plate from the turning frame at the time of about the end of the turning operation; and a horizontal transfer conveyor for supporting the lower edge of the glass plate transferred to the transfer frame, whereby the glass plate is transferred from the turning frame to the transfer frame and the horizontal transfer conveyor transfers the glass plate to a pallet by the turning operation of the transfer frame and the forward movement of the horizontal transfer conveyor.
