摘要： There are provided an electrodeposited copper foil with carrier that can be used for manufacturing a printed wiring board that excels in the finished accuracy of the resistor circuit in comparison with a conventional printed wiring board with resistor circuits, and a method for manufacturing such a printed wiring board with resistor circuits. The method for manufacturing a printed wiring board with resistor circuits comprises the steps of previously forming copper foil circuits using a copper foil for a printed wiring board with resistor circuits comprising a nickel layer for forming a resistor circuit between a copper carrier and a copper foil layer for forming the circuit, whose surface layer is subjected to a nodular treatment, using a copper etching solution that does not etch the nickel layer; fabricating a copper clad laminate using the copper foil after forming the copper circuits, and a prepreg composing a resin base material; removing the copper carrier to expose the nickel layer for forming the resistor circuit, and etching the resistor circuits to form the nickel resistor-circuits.

摘要： An object of the invention is to provide a surface-treated copper foil capable of consistently attaining a percent loss of peel strength in resistance against hydrochloric acid degradation of 10% or less as measured on a copper pattern prepared from the copper foil and having a line width of 0.2 mm, by bringing out the maximum effect of the silane coupling agent employed in brass-plated anti-corrosive copper foil. The Another object is to impart excellent moisture resistance to the surface-treated copper foil. In order to attain these objects, the invention provides a surface-treated copper foil for producing printed wiring boards which has been subjected to nodular treatment and anti-corrosion treatment of a surface of a copper foil, wherein the anti-corrosion treatment includes forming a zinc-copper (brass) plating layer on a surface of the copper foil; forming an electrodeposited chromate layer on the zinc-copper (brass) plating layer; forming a silane-coupling-agent-adsorbed layer on the electrodeposited chromate layer; and drying the copper foil for 2-6 seconds such that the copper foil reaches 105° C.-200° C.

摘要： A spindle motor has a rotor supported by a stator through a thrust bearing and a radial bearing. At least the thrust bearing is a hydrodynamic bearing. The spindle motor is provided with a device for adjusting the thrust laod that is applied to the thrust bearing. The load adjusting device has an electromagnet that is provided on the stator and a permanent magnet that is provided on the rotor in opposing relation to the electromagnet. Either the repelling force or the attraction force, which acts between the electromagnet and the permanent magnet, is controlled by changing the current supplied to the electromagnet.

摘要： A new reversible heat sensitive recording composition for erasable recording is disclosed which is used as a recording or marking material that is capable of erasure at a specific temperature so that coloring or decoloring can be controlled to occur at desired temperature ranges. This range or the hysteresis value of the composition is determined by the .DELTA.T value of the contained ester compound. In addition, the composition can provide a wide variety of hues and can readily be prepared. The marking or recording drawn in this composition can be maintained at room temperature or less.

摘要： A drying oil such as isomerized linseed oil, dehydrated castor oil or the like oil which has an iodine value of more than 140 and a content of conjugated double bonds of less than 50% is reacted with isopropenylphenol and/or oligomers thereof in an amount, by weight, of 0.1-2 times as great as that of the drying oil in the presence of a small amount of an acid at a temperature of 65-150.degree. C. for 0.5-3 hours. By the reaction, isopropenylphenol and/or its oligomers are introduced to the drying oil while leaving the double bonds of the oil as they are without disappearance. The thus introduced oil is further reacted with a phenol or phenols under strongly acidic conditions to introduce the phenols thereto. The drying oil which has been introduced with the isopropenylphenol and/or its oligomers and also with the phenols is mixed with a phenol or phenols and then reacted with formaldehyde to give a modified phenolic resin. This phenolic resin is useful for making a phenolic laminate with improved flexibility, punching quality and water proof.
