Filed: 1993-09-10
Abstract: PURPOSE:To more efficiently prevent the corrosion of a city water pipeline in which a coat consisting essentially of calcium carbonate is formed by incorporating calcium hydrogen carbonate into the city water by adjusting the content of calcium hydrogen carbonate as the thickness of the coat is increased or decreased. CONSTITUTION:When calcium hydrogen carbonate is incorporated into city water, the content is adjusted in accordance with the thickness of the coat consisting essentially of calcium carbonate and formed in the city water pipeline. The thickness of the coat formed in the branch pipe at the terminal of the pipeline is periodically measured, the Langelier index of the city water is kept at -1 to 0.5, and the content of calcium hydrogen carbonate is adjusted to decrease the index when the coat thickness is increased to 400-500mum and adjusted to increase the index when the coat is dissolved and its thickness is decreased to 100-50mum. Consequently, the coat thickness is kept in a specified range, and the corrosion of the pipeline is effectively prevented.

IPC: B60L7/04
Filed: 1983-12-23
Abstract: PURPOSE:To improve the efficiency of power consumption at constant and acceleration time on a flat road by operating a motor brake circuit only at braking or decelerating time. CONSTITUTION:A motor drive signal VC1 and a motor brake signal Vi are outputted on the basis of an acceleration signal Vac from an accelerator ACC and an output Vosc of a sawtooth oscillator OSC.

Title: Multilayer displacement element
Inventor: WATANABE JUNICHI
IPC: H01L41/083
Filed: 1993-10-07
Abstract: PURPOSE:To enhance durability by enclosing the inner electrode completely in a laminate while exposing only the connecting part with the outer electrode to the side face of the laminate and specifying the lateral dimension at a non- displacement part formed between the fringe part of displacement part and the side face of the laminate thereby preventing migration and crack. CONSTITUTION:A thin plate 1 is paired with an inner electrode 2 made of a conductive material and the projection area of the inner electrode 2 is set smaller than that of the thin plate 1 so that contact with the atmosphere is blocked thus preventing the moisture in the outer air from intruding into a laminate 5. When the number of layers constituting the laminate 5 is set at fifty or less, the tensile stress at the border of alternating electrode elements does not exceed the fracture stress of the element and cracking is prevented. Furthermore, when the lateral dimension at the non-displacement part 9 is at 0.3 mm or less, bonding strength at the non-displacement part 9 is increased and piezoelectric characteristics at the displacement part 8 are suppressed thus relaxing the stress. A lead wire 10 is then connected electrically and mechanically with the side face of the element by soldering.

Because the printer paper 12 can be loaded on the holder 1 directly, need of a conventionally required holding shaft is eliminated.
