An appratus for inspecting lightness on the surface of an object having at least first and second surface portions different in lightness, wherein an image of the first and second surface portions of the object are taken under appropriate illumination, the taken image is memorized, first and second reference lightness of the first and second surface portions are defined respectively, whether or not each pixel of the taken image belongs to either one of pixel regions defining the first and second surface portions are determined in accordance with values defining preliminarily memorized pixel regions respectively, lightness difference between each pixel of the taken image corresponding to the first surface portion and the first reference lightness is calculated, lightness difference between each pixel of the taken image corresponding to the second surface portion and said second reference lightness are calculated, and quality in lightness on the surface of the object are determined on a basis of the respective lightness difference.

A thermosensitive stencil paper contains a main component layer formed of a thermoplastic film and an ink-permeable support bonded together with adhesive, in which the ink-permeable support is a porous thin paper containing polynosic fibers as the main fibrous component. Optionally, the thermosensitive stencil paper has a plastic film layer whose surface is coated with a mold release layer containing as a main component a silicone oil having a kinematic viscosity of 500,000 cs or more. The transfer operation of the stencil paper in an automatic printer is excellent and its ink feeding performance during printing is high because of the polynosic fiber-containing porous thin paper support. Nonprinted spot defects are reduced because of the small number of bundled fibers in the stencil paper. Stencil paper containing the mold release layer are free of offsetting when rolled and cause no sticking for a long period of time, thereby providing thermosensitive stencil paper with excellent performance.

A closed mixing machine includes a pair of nonintermeshed rotors rotatable in chambers at a predetermined differential rotation ratio and having respective rotor tips set at a predetermined differential phase angle. The predetermined differential rotation ratio is set to be 1.0 and the predetermined differential phase angle is set to be 0 to 45 degrees so that the mixing machine performs improved macro-dispersion.

Disclosed is fiber-reinforced thermoplastic resin pellets that satisfy the quality stability (homogeneous impregnation, deterioration prevention of reinforcing fiber) of the molding material and the strength performance of the molded product, using natural discontinuous fiber as the reinforcing fiber, and a manufacturing method of the pellets. A plurality of spun yarns with No. 5 to 80 counts are twisted 10 to 200 turns/m and pultruded when fiber-reinforced thermoplastic pellets containing natural fiber as the reinforcing fiber are manufactured by the impregnating pultrusion method.
摘要:
In a large system such as a parallel computer system, a scan device forms a scan path by hierarchically connecting input and output signal lines of integrated circuits, thereby enabling creating of a short scan path which contain only the necessary integrated circuits. This allows a scan test such as JTAG-SCAN to be effectively made.

A closed type kneader has two rotors rotatably mounted in a casing for rotation about parallel axes. Two blades extend from each of the rotors such that the blades of the rotors intermesh. Each rotor has both a main blade and an auxiliary blade. The auxiliary blade has a length not less than one-half of the length of the rotor and an angle of torsion not smaller than 0.degree. in the same direction as the angle of torsion of the main blade. The rotors are rotated in synchronism with one another so that the main blade tip of each rotor may be in phase with the auxiliary blade tip of the other rotor at the axial centers of the rotors.
摘要:
A closed mixing machine suitable for mixing rubber materials, which includes a closed mixing chamber and a pair of rotors received in the chamber for rotating in opposite directions, wheren the rotor tips' clearance and the rotor rotation speed are increased up to values greater than typical values of the conventional mixing machine. Accoridng to this arrangement, mixing productivity is increased by a maximum of 70% with the even discharge temperature and energy consumption is reduced in comparison with the conventional machine.
摘要:
Disclosed is a closed type mixing and kneading apparatus with two juxtaposed double-wing rotors providing increased mixing and increased shearing action. One of the wings of each rotor has a length ratio of 0.6 to 0.9 relative to the total length of the rotor at a twist angle of 10.degree. to 40.degree.. The two wings of each rotor are overlapped by between 0.2 and 0.8 times the total length of the rotor.
