摘要:
A pump for use in a paint application apparatus which is so constructed that there is provided a clearance between an appropriate portion of an internal surface of a casing of the pump and an external periphery of protruded portions of a rotor of the pump, and there is provided another clearance between an internal periphery of the protruded portions of the rotor and an external periphery of a cylinder section of a grand box of the pump. Further, in the pump, an appropriate portion of the internal surface of the casing of the pump, the external and internal peripheries of the rotor of the pump and the external periphery each of the cylinder section of the grand boxes are made hard by quenching, applying thereto an extremely hard alloy or spraying thereonto a hard material such as molybdenum. With the arrangement mentioned above, a paint including a vast plurality of glass beads and aggregates such as a silica and limestone in the form of sand, can be pressedly conveyed without any difficulty and consequently, the pump can retain a long and useful life.

The present invention has its object to provide a coating material with a gas-barrier property which can give a very transparent packaging material with a satisfactory gas-barrier property when it has a thin gas-barrier layer and, when it has a gas-barrier layer with an ordinary thickness, can give a packaging material with a higher gas-barrier property, a process for producing such coating material with a gas-barrier property, and a packaging container with a high gas-barrier level obtained by coating with such coating material with a gas-barrier property.The present invention provides a coating material composition with a gas-barrier property which comprises, as essential components, an ethylene-vinyl alcohol copolymer (A) obtained by saponifying an ethylene-vinyl acetate copolymer, an inorganic layered compound (B) and a solvent, wherein the total amount of (A) and (B) is 1 to 30% by mass and the mass ratio (A)/(B) is (30/70) to (50/50).
摘要:
A balanced-to-unbalanced transformer for interconnecting a balanced signal transmitted on a balanced cable and an unbalanced signal transmitted on an unbalanced cable through a transformer. Common-mode impedance is reduced by grounding a center point of two or more impedance elements between signal lines on the balanced cable side of the transformer to a signal circuit ground or a frame ground on the unbalanced cable side of the transformer.

Two-wire television interphone system is arranged to discriminate by a line voltage discriminator incorporated in a master device a line voltage variation due to a calling operation on the side of a branch device, to actuate a voltage controller in the branch device to shift the system from standby state to operation state, and to drive a call signal generator in the branch device for actuation of a call signal receiver in the master device. The system is thus made to have a power supply circuit energized for a power supply to the system only when required for effecting the calling operation, talking between the both devices, and so on.

The invention relates to a printing method by an offset printing press and an offset printing press by which a substrate process is carried out for low-whiteness printing paper such as paper for newspaper with aqueous substrate treatment agent so that the print quality can be improved. In the invention, in order to suppress occurrence of a curl of printing paper, substrate treatment agent containing solid fine particles and a binder component is supplied to a printing face of printing paper, and the substrate treatment agent is dried to form a porous layer having a great number of holes having a smaller diameter than that of pigment contained in printing ink from the solid fine particles and the binder resin. Then, offset printing is carried out on the printing paper.

A microwave plane antenna including rows comprising pairs of parallel conductive line antenna elements configured as a pair of out-of-phase square waves and a signal feed circuit of strip lines arranged as a corporate feed network. The respective conducting paths which run from a main feed inlet end of the circuit to each signal receiving end of the respective elements being varied in length, so that the main beam direction can be set in a plane including that of the antenna and normal to lengthwise axis of the antenna elements for a remarkable increase in the reception gain.
摘要:
A process for producing a resin-coated pigment capable of providing an ink and a paint being superior in dispersion stability of a pigment and having rapid drying property, high gloss and density without containing those such as an organic solvent and a salt that cause the lowering of performance of pigment dispersion, characterized in that a pigment is dispersed in an aqueous solution in which an anionic group-containing resin is dissolved in the presence of a basic compound and then, the anionic group-containing resin is precipitated on the surface of the pigment by removing the basic compound in the aqueous solution, using an ion exchange means.
摘要:
The present invention provides: an inorganic layered compound dispersion prepared by cleaving the inorganic layered compound to a thinner layer level and capable of providing high corrosion resistance and gas barrier properties when utilized in the form of a coating composition or a gas barrier coating composition; a gas barrier coating composition with which films having high transparency and satisfactory gas barrier properties can be obtained at low cost when the gas barrier layers are formed ina thinner film form and, when the filmthickness is increased, films having good transparency and still better gas barrier properties can be obtained; and plastic- or paper-based gas barrier packaging containers having high gas barrier performance characteristics as obtainable by application of such a gas barrier coating composition. The present invention provides: an inorganic layered compound dispersion, wherein an inorganic layered compound (b) is dispersed using a peroxide (a) in a dispersion medium.
摘要:
A wireless transmission system includes a plurality of terminal units, a specific one of which is provided with a transmission/receiving circuit that transmits a reference signal of a local oscillation frequency, while all others of which are provided respectively with a transmission/receiving circuit that prepares, on the basis of the reference signal received, a local oscillation frequency signal for frequency conversion of transmitting/receiving frequency signal and intermediate frequency signal, to thereby realize the system at lower costs even when a high local oscillation frequency is employed.
