Abstract: A contact probe for carrying out an electric test by being brought into contact with respective terminals of a liquid crystal display device and a liquid crystal display testing device utilizing such a contact probe. The contact probe has a structure which may include a metal film attached to a nonconductive resin film, which prevents intervals between contact pins from being changed, for example based on changes in humidity. A nonconductive resin film may also be attached on the metal film. An elastic film may also be attached to a nonconductive resin film to ensure a proper orientation of contact pins in a testing operation. The liquid crystal display testing device can utilize such contact probes.

Abstract: Metal is electrolytically precipitated on a cathode plate except for a portion thereof. The non-precipitated portion enables easy peeling of the precipitated metal from the cathode plate. The ceramic coating film is formed on the non-precipitated portion and prevents intrusion of electrolytic acid between the ceramic coating film and the cathode plate. The life of the coating is prolonged. The polishing of the cathode plate can be automatized.

Abstract: A method of purifying a copper electrolytic solution circulated in a copper electrorefining system, wherein a portion of the solution is withdrawn and recycled to the system after purification treatment. The purification treatment includes the addition of a hydrosulfide to the withdrawn solution to generate only the necessary quantity of hydrogen sulfide gas required in the reaction. The hydrogen sulfide gas generated is utilized for purification treatment. One process comprises dividing the solution withdrawn into two portions. Sodium hydrosulfide is added to the first portion to precipitate and separate metals as sulfides. Excess sodium hydrosulfide is further added to the first portion for reaction with residual sulfuric acid in the solution to generate hydrogen sulfide gas, then contacting the second divided portion with the hydrogen sulfide gas thus produced to precipitate and separate metals in the form of sulfides. The filtrate is then recycled to an electrorefining system.

Abstract: A sputtering target of platinum-cobalt alloy is disclosed which contains 10 to 55% by weight of platinum; 1 to 15% by weight of a first additional element selected from the group consisting of nickel and tantalum; no more than 1.5% by weight of a second additional element selected from the group consisting of boron, titanium, lanthanum, cerium, neodymium, beryllium, calcium, zirconium, and silicon; no more than 20% by weight of chromium; and balance cobalt. A method for manufacturing the sputtering target is also disclosed. In the method, a platinum-cobalt alloy containing specific ingredients in predetermined amounts is first prepared. Then, the platinum-cobalt alloy is subjected to hot plastic working with a thickness reduction of no less than 30%. Subsequently, the alloy thus hot worked is subjected to a cold plastic working with a thickness reduction of no less than 5% at a temperature less than the recrystallization temperature of the alloy.

Abstract: A direct-coupling control method capable of improving fuel efficiency by performing slip direct-coupling control of a torque converter, in which a driving force transmission of an automatic transmission is operated under an approximate direct-coupling condition that permits slight slippage of the torque converter, in a predetermined operating range of the automatic transmission such as a low speed range thereof, and capable of positively detecting and preventing direct-coupling vibration caused by deterioration of hydraulic oil or the like.

Abstract: An apparatus for and a method of manufacturing a fiber reinforced thermoplastic sheet-shaped molding including a pre-impregnating process and a final impregnating process. A sheet of thermoplastic resin and a web of reinforcement fibers are supplied through the pre-impregnating process during which the thermoplastic resin is sucked under the influence of a suction force so as to partially penetrate into interstices in the reinforcement fiber web while both are transported around and by a perforated rotary drum, thereby to form a first preformed sheet. The first preformed sheet is subsequently supplied to the final impregnating process during which an impregnating machine is employed. As the first preformed sheet is passed through the impregnating machine while compressed inwardly and heated, the thermoplastic resin is allowed to completely penetrate into the interstices in the reinforcement fiber web to complete the fiber reinforced thermoplastic sheet-shaped molding upon cooling thereof.
