Abstract: A component supply device including an accommodation body installation unit in which one or more accommodation bodies each accommodating components are installable, the component supply device sequentially operates the one or more accommodation bodies to supply each of the components to a predetermined component supply position. The component supply device comprises a supply state detector which detects a supply state of components in total accommodated in the one or more accommodation bodies installed on the accommodation body installation unit, a determination unit which determines, based on the supply state, a state of the accommodation body installation unit among (i) an installation disabled state, (ii) an installation enabled state, and (iii) an installation required state, and a notifier which notifies a worker of the state of the accommodation body installation unit determined by the determination unit.

Abstract: Provided are a coating film-forming composition for forming a coating film on a metal surface that exhibits excellent adhesiveness between a metal and a resin, and a surface-treated metal member having a coating film formed by using the composition. The coating film-forming composition is a solution containing a silane coupling agent having an amino group, a metallic ion and a halide ion. The metallic ion is preferably a copper ion, and a copper ion concentration in the solution is preferably 0.1 to 60 mM. The amount of Si based on the amount of Cu in the solution is preferably 30 or less, in terms of molar ratio. The pH of the solution is preferably 2.8 to 6.2.

Abstract: An etching method is capable of etching titanium selectively in the presence of copper. An etching liquid used in the method is low in toxicity and excellent in storage stability. The etching liquid includes at least one acid, such as, sulfuric acid, hydrochloric acid, or trichloroacetic acid, and at least one organic sulfur compound, such as a thioketone compound or a thioether compound.

Abstract: A tape feeder (a component supplying device) which transports a carrier tape covered with a cover tape and storing components to a component pick-up position, peels off the cover tape before the component pick-up position, and supplies the stored components to a component mounter, the tape feeder including photo-switch (a detector) which detects presence or absence of tension acting on the cover tape, the cover tape is peeled off from the carrier tape, a feeder storage unit (a storage unit) which stores the presence or absence of tension which is detected by the photo-switch, and an operation determination unit (a determination unit) which determines a processing operation performed when power which is supplied to the tape feeder is reintroduced based on the presence or absence of tension which is detected.
