Abstract: A wooden water tank for a building has a tank wall, a tank bottom and a wooden dividing wall across the tank defining at least two water compartments. There are attachments between the foregoing parts, and leak preventing connections between parts. The dividing wall is a sequential series of staves or boards extending horizontally and pressed secured together for leak prevention.

Abstract: A method of mounting an electronic component having at least one contact extending across a part of its undersurface may include providing a support smaller in area than the undersurface of the component and having a contact pad for connection to the contact. The contact pad may have a first portion extending across an upper surface of the support adjacent one edge and a second portion extending from the edge across a side surface of the support. The method may also include positioning the electronic component and the support with the undersurface of the component adjacent the upper surface of the support. This is done so that the first portion of the contact pad is aligned with and spaced apart from a first portion of the contact, and the second portion of the contact pad is aligned with and disposed inwardly of a second portion of the contact.
