摘要:
A long fiber-reinforced polymer alloy resin composition (C) is provided which is obtained by blending a master batch (A) containing a long fiber reinforcement (a2) having a length of 3 to 30 mm in a resin matrix of a polyamide resin (a1), with a substantially polymer-alloyed resin diluent (B) obtained by melt kneading 45 to 20% by weight of a crystalline polyolefin resin (b1) and 55 to 80% by weight of a polyamide resin (b2), the crystalline polyolefin resin (b1) containing a modified olefin crystalline polymer (b11) having been substantially modified with unsaturated carboxylic acids. In this resin composition (C), the amount of the long fiber reinforcement (a2) is in the range of 10 to 60% by weight, and the amount of the crystalline polyolefin resin (b1) in resin components ((a1)+(b1)+(2)) other than the long finer reinforcement (a2) is in the range of 20 to 45% by weight. This resin composition (C) is excellent in tensile strength and particularly excellent in repeated impact resistance properties.
摘要:
An ink-jet recording apparatus comprising an ink-discharging opening coupled to an ink chamber for discharging ink therefrom toward a recording sheet. The ink-discharging opening is formed at a center and bottom of a concave portion formed in a thin plate made of an insulating material. A first electrode is provided on one surface of the thin plate and around the concave portion and a second electrode is provided on the other surface of the thin plate and at the vicinity of the ink-discharging opening, the first and second electrodes being electrically coupled to an ink-discharging control signal source. This arrangement can omit an air supply system to simplify the structure of the recording apparatus.

摘要:
An optical recording medium of a substrate and a thin metal film laminated thereon formed of a noble metal (A), a chalcogen (B) and bismuth (C) as essential components in amounts within the region of the phase diagram of FIG. 1 defined by the points: a; (A.sub.80 B.sub.15 C.sub.5), b; (A.sub.15 B.sub.80 C.sub.5), c; (A.sub.2 B.sub.80 C.sub.18), d; (A.sub.2 B.sub.49 C.sub.49) and e; (A.sub.80 B.sub.10 C.sub.10), said medium capable of absorbing a laser beam of a specific wavelength region thereby recording information by the pits of cavities formed in the film by the laser beam.
摘要:
A plurality of electronic component chips (108) are stored in a space (109) defined in the interior of a case (111). The case is provided with an outlet (110) which communicates with the space for discharging the electronic component chips stored in the space. This outlet is closed by an openable closure. When the case is fixed to a hopper (102) included in an apparatus for supplying electronic component chips, the outlet is opened so that the electronic component chips are introduced into the hopper.
摘要:
A thermal-electrostatic ink jet recording head is formed of two spaced-apart insulating substrates with an electrostatic field forming electrode and an array of electric heating elements in the slit between the substrates. The heating elements are paired and each of the adjacent heating elements of a pair joined by a common electrode, with each heater having an independent electrode connectable to a switching circuit for selectively heating portions of the ink under the influence of an electrostatic field to cause ink in the heated portions to be jetted. The common electrode preferably is U-shaped with each of its free ends connected to the inner ends of the adjacent electrodes of a pair.
摘要:
A process for producing an optical recording medium, comprising heat-treating an optical recording medium formed of a thin metal film on the minutely roughened surface of a plastic substrate, the medium being capable of strongly absorbing laser light of a specific wavelength region thereby being able to be written upon.
摘要:
A non-impact ink jet image recording head for jetting a liquid coloring agent, such as ink, at a recording member (paper) wherein both electric and thermal energies are applied to ink contained in the image recording head; wherein heating elements are provided in a horizontal base and the ink is contained above the heating elements. Preferably, a pair of damlike members, with a discharge portion, contain the ink in a channel above the heating elements.
摘要:
A diaphragm for an electro-acoustic transducer comprising a sheet formed from a mixture of a polymer and mica, where the sheet contains (a) 30 to 95% by weight of a polymer selected from among polyolefins, polyesters, and polyamides and (b) 5 to 70% by weight of mica having a weight-average flake diameter not exceeding 500 microns and a weight-average aspect ratio of at least 10. By adding the specified mica, the sheet has a drastically improved dynamic modulus and a substantially unchanged loss tangent.

Provided are: a powdered material for slush molding; and a manufacturing process therefor. The powdered material is less odorous, exhibits excellent powder fluidity, and does not suffer from troubles resulting from the sliding-down or agglomeration of a pigment even when the resin particles have been pigmented on the surfaces thereof. Thus, the powdered material ensures high productivity. The powdered material is a powdered polyurethane urea resin composition which comprises (D) a polyurethane urea resin that has a total content of bimolecular condensate of acetone, bimolecular condensate of methyl ethyl ketone, and bimolecular condensate of methyl isobutyl ketone of 1,000 ppm or less and (N) an additive, wherein the polyurethane urea resin (D) takes the form of thermoplastic polyurethane urea resin particles (P) that have a volume-mean particle diameter of 20 to 500 μm and that have protrusions and recesses on the surfaces. The powdered polyurethane urea resin composition is manufactured by a manufacturing process which includes a step of mixing (A) an isocyanato-terminated urethane prepolymer with (B) an alicyclic diamine and/or an aliphatic diamine in an aqueous medium by stirring to form the resin particles (P).
