    • A mechanism, of a camera, for surely resetting a microcomputer at time of switching among a plurality of types of power sources. In the mechanism in which a manual operation dial for switching among the plurality of types of power sources is rotated to slide an electrical contact piece over a predetermined electrically conductive/non-conductive pattern so that a desired power source type is selected, an electric conductivity/non-conductivity between an IC and a negative terminal changes, immediately before an electric power across a positive terminal and the negative terminal is changed from “ON” to “OFF”, and immediately after the electric power is changed from “OFF” to “ON”. In association with the change, the IC outputs a reset signal to the microcomputer of the camera.

    • A method of making a printed circuit board includes providing a substrate coated with a conductive layer, developing a first photoresist layer on the conductive layer to define a first conductive pattern of the desired circuit configuration having a plurality of discontinuous segments, and a second conductive pattern interconnecting the discontinuous segments of the desired circuit configuration. A second layer of photoresist is positioned across the whole surface of the substrate except at least a selected portion of the first conductive pattern, and the substrate is electrically activated during a coating process for depositing conductive material on the selected portion of the first conductive pattern. The first conductive pattern is subsequently coated with photoresist, and the second conductive pattern, which is now exposed on the substrate, is subject to an etching process to effectively remove all of the second conductive pattern.
    • 制造印刷电路板的方法包括提供涂覆有导电层的基板,在导电层上显影第一光致抗蚀剂层以限定具有多个不连续段的所需电路结构的第一导电图案,以及第二导电图案 互连所需电路配置的不连续段。 除了至少第一导电图案的选定部分之外,第二层光致抗蚀剂被定位在基板的整个表面上,并且在用于在第一导电图案的选定部分上沉积导电材料的涂覆工艺期间基板被电激活。 第一导电图案随后用光致抗蚀剂涂覆,并且现在暴露在基板上的第二导电图案经受蚀刻工艺以有效地去除所有第二导电图案。
