Abstract: A printer includes a platen on which a recording medium is placed, an ink head including a nozzle that discharges ink onto the recording medium placed on the platen and that moves in a main scanning direction, an upstream guide located on an upstream side of the platen in a secondary scanning direction and that guides the recording medium, the upstream guide including an upper surface tilted obliquely downward from a downstream side to the upstream side in the secondary scanning direction, and grit rollers provided in the platen and that move the recording medium in the secondary scanning direction. The upstream guide is recessed from the upper surface of the upstream guide, and includes a concave recess that indicates a position of each of the grit rollers in the main scanning direction so that a position of the grit roller is easily acknowledged when the recording medium is placed on the platen.

Abstract: A printer includes a first guide disposed downstream of a platen in a sub-scanning direction to guide movement of a recording medium, a second guide disposed below the first guide and downstream of the first guide in the sub-scanning direction to guide movement of the recording medium, and a dryer facing the first guide and the second guide to send air toward the recording medium. The dryer includes a body case including an outlet port that is open toward the second guide, a fan to send air toward the recording medium through the outlet port, and a heater to heat air sent by the fan. The first guide has a thermal conductivity higher than a thermal conductivity of the second guide.

Abstract: A printer includes a medium supplier including a shaft support, to which a supply shaft of a roll medium is detachably attached, a medium temporary placement support located below the shaft support of the medium supplier and that receives and supports the roll medium prior to being attached to the medium supplier, and a conveyor that conveys a medium in a conveyance direction that is perpendicular or substantially perpendicular to an axial direction of the supply shaft, the medium being unwound from the supply shaft. The medium temporary placement support includes a support bar that extends in the axial direction, and a placement seat supported by the support bar. The placement seat includes a placement surface on which the roll medium is placed and that extends in the conveyance direction, and a curved portion that includes a convex curve in an upstream end portion of the placement surface in the conveyance direction.

Abstract: In a process for producing an air-quench-toughened glass plate, defective glass plates containing nickel sulfide (NiS) are removed by compulsory breaking the glass plates. Such compulsory breakage is carried out in the course of a batch-manner soaking process carried out after a toughening step; in the course of a toughening step carried out after generation of cracks in an annealing step; in the course of a toughening step carried out after generation of cracks in a pretreatment step; or in the course of a continuous annealing step carried out after a toughening step. Through the method, NiS-free toughened glass plates of high-quality can be produced.

Abstract: The present invention provides a raw material composition for soda-lime glass capable of effectively suppressing formation of nickel sulfide (NiS) in the course of melting of the glass raw material. A nickel sulfide (NiS) impurity present in soda-lime glass is formed in a high-temperature vitrification step in which metal particles containing Ni and an Ni component of stainless steel used for the interior of a melting furnace, which are mixed into glass raw material, react at high temperature with a sulfur (S) component in Na2SO4 serving as a glass raw material. However, when an additive containing an oxide, a chloride, a sulfate, or a nitrate of a metal is added in a very small amount and in advance to glass raw material, formation of NiS by the reaction between Ni and S in the course of melting can be suppressed or completely eliminated.

Abstract: A face panel for a cathode-ray tube is coated with an antireflection film by forming, on the outer surface thereof in this order, a 44.9 nm-thick praseodymium titanate film as a first layer, a 4.9 nm-thick film of a nickel-iron alloy as a second layer, a 53.4 nm-thick praseodymium titanate film as a third layer, a 3.9 nm-thick film of a nickel-iron alloy as a fourth layer, a 20.6 nm-thick praseodymium titanate film as a fifth layer, and an 84.7 nm-thick magnesium fluoride film as a sixth layer. This coated face panel is free from the problem that conventional cathode-ray tube face panels coated on the outer surface with an antireflection film comprising superposed metal films and transparent dielectric films make the cathode-ray tubes exhibit double images although effective in diminishing the reflection of external light on the surface of the cathode-ray tubes and in enhancing display contrast.
