摘要:
An anti-reflection film is produced on the panel surface of a cathode-ray tube by: (A) preparing a solution for forming an anti-reflection film, which contains water and a metal alkoxide having the formula, M(OR).sub.n wherein M is a metal selected from the group consisting of Si, Ti, Al, Zr, Sn, In, Sb and Zn; R is an alkyl group having 1-10 carbon atoms; n is an integer of from 1 to 8; and when n is not 1, the alkyl groups represented by R may be the same or different, (B) coating the solution for forming an anti-reflection film on the outermost surface of the panel of a cathode-ray tube, and (C) applying an ultraviolet light to the solution for forming an anti-reflection film coated on said surface to cure the solution to form a transparent film with fine roughness. This production method is carried out using an apparatus having: (a) a coating means for coating the above solution for forming an anti-reflection film on the outermost surface of the panel of a cathode-ray tube, (b) a transferring means for transferring the solution-coated cathode-ray tube, and (c) an ultraviolet light-applying means for photocuring the solution coated on the cathode-ray tube during the transfer of the solution-coated cathode-ray tube. In the above method, when a silicon alkoxide is used as the metal alkoxide, there can be obtained a cathode-ray tube having an anti-reflection film made of alkali-free silica on the outermost surface of the panel, said anti-reflection film giving a ratio of Si-O-Si peak intensity to Si-OH peak intensity of 4 or more when measured for infrared spectrum.
摘要:
Two metal plates are joined together by curling, where projections are formed in advance at an edge of one of the two metal plates and those projections are forcibly advanced into an edge or the other of the two metal plates so as to interlock the metal plates without any mutual displacement therebetween and not requiring any positioning of projections or cut and raised portions with respect to holes.

A method of producing a press-connecting joint connector and a method of press-connecting wires, in which the step of mounting press-connecting terminals in a housing is eliminated thereby reducing the production time, the housing-forming mold is simplified, and connective portions are prevented from being easily ruptured. Linked press-connecting terminal groups (32) are inserted-molded integrally in housings (34), respectively, thereby forming press-connecting joint connectors (30) which are linked together by a linkage plate (40) which is integral with the press-connecting terminal groups (32). Thus, when molding the housings (34), the press-connecting terminal groups (32) are formed integrally with the housings (34), respectively, so that the step of inserting the press-connecting terminal groups into the respective housings (34) is eliminated. The housings (34) can be molded independently of each other so that the housing (34) can be simplified, and linkage portions of the press-connecting joint connectors (30) have an increased strength.

摘要:
A magnetic recording has very low warp characteristics but excellent film characteristics. Particularly, the recording medium has a high coercivity with a small range of coercivity distribution, with a warp characteristic below 3 .mu.m per radial inch. The medium is formed by heating a substrate at a high temperature with a temperature distribution on the substrate that is improved by the use of a heat distribution mask, which reduces the temperature distribution of the substrate to below .+-.3%.

The present invention provides a thread wound golf ball which keeps good hit feeling inherently holding in thread wound golf balls and attains long flying distance which is equal to that attained by the two-piece solid golf ball. The thread wound golf ball comprises a center composed of a vulcanized molded article of a rubber composition, a thread rubber layer formed on said center and a cover covering on said thread rubber layer, wherein said center has a diameter of 30 to 35 mm and a strain amount formed between an initial loading of 10 kg and a final loading of 30 kg is 1.2 to 2.5 mm. The cover of the thread rubber layer has many dimples thereon and the product of total volume of the dimples and the diameter of the center is 8,500 to 11,000 mm.sup.3.mm.
摘要:
A press-connecting joint connector with which electrical wires can be readily connected to each other, and a method of press-connecting the electrical wires to the 5 connector. The joint connector (31) includes a connector body (33) with a wire inserting section (47) in which the wires are to be inserted and a press-connecting blade (43) provided in the wire inserting section (47). The wires (W1) and (W2) are inserted in the wire inserting section (47) and the insulation of the wires is cut by the blade such that the blade electrically interconnects the wires. Thereafter, a cutter is inserted into the connector body to thereby cut the waste end portion (105) of at least one of the wires inside the connector body (33). The cutting step may be performed simultaneously to when the wires are pressed into the blades.

摘要:
A molded cushioning article is made by stuffing a bulky, tape-form nonwoven web such as sliver in a mold cavity and thereafter heat-treating the thus-formed molded form to fusion-bond intersecting points of fibers. Stuffing of the tape-form nonwoven web is effected by laying and superposing it in to-and-fro movements on a molding surface of a mold permeable to air with a space on a backside of the molding surface being kept under reduced pressure. The apparatus used has (a) means for feeding the tape-form nonwoven web into the mold, (b) a mold permeable to air, (c) a mold-supporting frame, (d) suction means for keeping the backside space under reduced pressure, (e) means for successively changing a positional correlation between means (a) and the molding surface, and (f) heat-treating means for fibers to be fusion-bonded.
摘要:
A high strength aluminum alloy is expressed by a general formula, Al.sub.a X.sub.b Mm.sub.c, in which "X" stands for at least one element selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu and Zr, "Mm" stands for a misch metal, a content "a" of aluminum falls in a range of from 95.2 to 97.5 atomic %, and a content "b" of "X" and a content "c" of the "Mm" fall in a hatched area enclosed by points "A," "B," "C" and "D" of accompanying FIG. 1 on atomic % basis, and whose metallic phase includes microcrystalline phases or mixed phases containing amorphous phases in a volume content of less than 50% and the balance of microcrystalline phases. As a result, the amorphous phases or the microcrystalline phases are dispersed uniformly in its base microcrystalline phases appropriately, and at the same time the thus generating base microcrystalline phases are reinforced by forming solid solutions including the "Mm" and the transition metal element "X" as well. Hence, the high strength aluminum alloy comes to have a low specific gravity and a high strength which have not been available from conventional Al amorphous alloys.
