Title: Method for plating can-type package
Inventor: KATO KAZUYUKI
IPC: C25D5/02
Filed: 1990-11-20
Abstract: PURPOSE:To thickly plate only the desired part and to obtain a highly reliable can-type package by alternately repeating resin coating and plating for each part with the plating thickness to be changed. CONSTITUTION:In the can-type package consisting of a base 1, a pin part 2 and a flange part 3, one part 6b (flange part 3) between the parts 6a and 6b to be plated is firstly coated with a resin 5b. The uncoated other part 6a (base part 1 and pin part 2) is then plated. The plated other part 6a is coated with a resin 5a. The first coating resin 5b is removed, and the one part 6b is plated and then further coated with the resin 5b. The resin 5a on the firstly plated other part 6b is released, and the part is further plated. Consequently, the base 1 and the pin part 2 as the contact points are thickly plated, the flange part 3 is thinly plated, and the reliability of the can-type package is improved.

IPC: E03C1/044
Filed: 1993-12-16
Abstract: PURPOSE:To enable the supply of water to be forcibly interrupted even during the automatic delivery thereof. CONSTITUTION:When a manual switch 34 is pressed in state where a sensor 26 detects hands or the like and the delivery of water (automatic delivery) is under way, the supply of water is stopped. Thereafter, so far as the sensor 26 keeps detecting the hands or the like, the supply of water or the interruption thereof is effectuated only by pressing the switch 34. When the switch 34 is pressed during the automatic delivery of water for interrupting the supply thereof, for example, the delivery of water again starts, if the switch is pressed once again. Also, the supply of water is interrupted, when the switch 34 is once more pressed. When the hands or the like is put back in the water stop state, a condition is reset to initial automatic water stop mode, thereby thereby allowing the performance of automatic water delivery with the sensor 26 or manual water delivery with the switch 34.
