Disclosed is a lens wherein characteristic direction of aberration and the like can be easily determined, and a lens processing method. A reference point of the characteristic direction of aberration and the like is clarified by providing a thin portion (103) of a flange section (102) with a mark portion (106), and the characteristic direction of aberration and the like can be easily and accurately determined. Furthermore, by not removing the whole flange section (102) in the thickness direction, the center position of the lens is prevented from shifting at the time of attaching the lens (100), and the processing portion of the lens (100) can be prevented from hitting a case and the like at the time of transferring the lens (100).

An electronic component feed system capable of feeding an electronic component mounting apparatus with a variety of electronic components such as chips, lead-type electronic components and the like in various forms. A plurality of feeder modules corresponding to sorts of electronic components to be mounted on printed circuit boards are stored in a storage kit and transferred through the storage kit to an electronic component feed section of the mounting apparatus on which a printed circuit board is held. Then, the electronic components are mounted on the printed circuit board by means of a mounting head.

An etching residue removal method includes a cleaning sequence. Preferably, the cleaning sequence has a first washing processing, first drying processing, stripper processing, rinsing processing, second washing processing and second drying processing. In the first washing processing, an insulation film and metal lines thereon are washed by pure water. In the first drying processing, the insulation film and metal lines are dried in a nitrogen atmosphere at room temperature, for example. In the stripper processing, the etching residue on the insulation film and metal lines are stripped by amine stripper, for example. In the rinsing processing, the insulation film and metal lines are rinsed with an IPA rinse solution, for example. In the second washing processing, the insulation film and metal lines are washed with pure water. In the second drying processing, the insulation film and metal lines are dried in the nitrogen atmosphere at room temperature, for example.

A switch mechanism comprises a switch button(s) to be pushed, a support board having a projecting portion(s) at a position corresponding to the switch button(s), and a switching assembly that is provided between the switch button and the support board and that switches an electrical connection state with the projecting portion in a state where the switch button is pushed. The support board comprises a through hole(s) around a position corresponding to the projecting portion. The through hole(s) is(are) formed such that the projecting portion is displaced in a pushing direction of the switch button in the state where the switch button is pushed.

A granulating method is a method in which powder containing a water-soluble component is granulated. In the disclosed granulating method, a dispersion element, wherein fine water droplets are dispersed in superheated steam, is expelled from a nozzle, and thus the dispersion element and powder in a flowing state come into contact with one another. It is preferable that the mass ratio of superheated steam contained in the dispersion element, as a mass ratio found from the theoretical flow amount of superheated steam expelled from the nozzle, and the actual flow amount of water supplied to the nozzle, be set in a range of 20-70 mass %.
