A data input system including electronic paper and a stylus writing device is disclosed. The electronic paper includes a transparent display substrate on which a number of optically readable code patterns have been formed, the optically readable code patterns representing positional information on a display surface, a rear surface substrate opposing the display substrate, and coloring particles that are enclosed between the display substrate and the rear surface substrate and that are movable by applying an electric or a magnetic field. The electronic paper displays an image due to motion of the particle. The stylus writing device includes a writing head provided at the end of the stylus for writing the image by applying an electric or a magnetic field to the electronic paper by contact and includes an optical reading device for optically reading the code patterns formed on the display surface where the end of the stylus contacts.
摘要:
In an internal combustion engine, inside of an engine exhaust passage, a hydrocarbon feed valve (15) and an exhaust purification catalyst (13) are arranged. The exhaust purification catalyst (13) is comprised of a mixture of a first catalyst in which platinum (51) and a basic layer (52) are carried on alumina (50) and a second catalyst in which rhodium (56) is carried on zirconia (55). The concentration of hydrocarbons which flow into the exhaust purification catalyst (13) is made to vibrate by within a predetermined range of amplitude of a 200 ppm or more and within a predetermined range of period of 5 second or less, whereby the NOx which is contained in exhaust gas is reduced at the exhaust purification catalyst (13).

A laser arc hybrid welding head and method which can form satisfactory beads at high speed are provided. A laser arc hybrid welding head (1) for welding a base material (W), which comprises aluminum steel sheets, by performing laser light irradiation and arc discharge, thereby combining laser welding and arc welding, splits inputted laser light (L0) into two beams, i.e., split laser light beams (L2a and L2b), then irradiates the base material (W) with the split laser light beams (L2a, L2b) while focusing these beams (L2a, L2b) on the base material (W), and also performs coaxial welding by generating an arc (A) from an arc electrode (20) disposed coaxially with the optical axis of the split laser light beams (L2a, L2b). Further, the transfer mode of a welding droplet from the arc electrode (20) is rendered spray transfer.

摘要:
A resin composition for an aqueous coating material that includes a propylene-butene resin component and/or propylene-ethylene-butene resin component (A), and a (meth)acrylic resin component (B), wherein the mass ratio between the propylene-butene resin component and/or propylene-ethylene-butene resin component (A) and the (meth)acrylic resin component (B) is within a range from 15:85 to 75:25. Also disclosed are a method for producing such a resin composition and an aqueous coating material. The present invention is able to provide a resin composition for an aqueous coating material that is useful as a binder within an aqueous coating material that uses no organic solvents or chlorine compounds, and yet exhibits excellent adhesion to polyolefin-based resins and is capable of forming a coating film that is resistant to discoloration and exhibits favorable resistance to the oils contained within gasoline, cosmetic products and foodstuffs and the like, and is also able to provide a method for producing the resin composition and an aqueous coating material that uses the resin composition.
摘要:
An exhaust gas analyzer of the present invention includes a sensor unit 11 installed in an exhaust path from an engine, applies laser light to exhaust gas emitted from the engine and receives laser light that has passed through the exhaust gas so as to measure the concentration of a component contained in the gas based on the received laser light. To an aperture 16 formed in a sensor base 15 of the sensor unit 11, an adjustment ring 40 in a circumferential face of which small holes 41 serving as a laser light passage portion is formed and whose inner circumferential face serves as an exhaust gas passage opening 21 is detachably fitted, whereby the sensor unit can be attached so as to conform to different inner diameters of exhaust tubes.
