摘要： A negative photoresist stripping liquid composition is provided which comprises from 30 to 75% by weight of dimethyl sulfoxide, from 20 to 65% by weight of 1,3-dimethyl-2-imidazolidinone, from 0.1 to 5% by weight of a tetraalkylammonium hydroxide and from 0.5 to 15% by weight of water. The composition has a superior stripping performance especially against photoresists that are alkali-developable and can form films of at least 20 .mu.m in thickness, and has no problem of freezing even when stored outdoors in the winter. The composition is useful for the stripping of negative photoresists for bump formation and for fabricating circuit substrates.

摘要： Provided is a surface-modified metal oxide powder obtained by treating a surface of a metal oxide powder, wherein a ratio (A/B) of an initial triboelectrostatic charge amount (A) at a time of one minute after dispersion of the surface-modified metal oxide powder into a ferrite carrier to a triboelectrostatic charge amount (B) after a lapse of 30 additional minutes is from 1.0 to 2.0, and the triboelectrostatic charge amount (B) is from −300 to +300 μC/g. The surface-modified metal oxide powder has a weaker charging property and a better stability over time of a triboelectrostatic charge amount than a conventional one; and thus, when this powder is used as an external additive, various properties including flowability and electrical charging can be stabilized, and in addition, problems such as fogging and image deterioration can be drastically remedied without significantly deteriorating characteristics as a developer and the like.

摘要： In a diversity receiver, each of first and second diversity branches includes an antenna and a high-frequency amplifier coupled thereto. A diversity decision circuit is coupled to the outputs of the amplifiers to generate a switching control signal identifying one of the outputs of the diversity branches having a higher field intensity value. A power switching circuit is provided for coupling a voltage source to one of the amplifiers according to the switching control signal so that power supply to the other amplifier is cut off.
