Title: Zinc alkaline cell
Inventor: MIURA AKIRA
IPC: H01M4/42
Filed: 1985-10-16
Abstract: PURPOSE:To obtain an overall efficiency of excellent discharge, preservation, and antileakage properties and the like with little environmental pollution, by applying a zinc alloy containing Zn as the main component, and specific ratio of In, Ni, Ca, Sr, and Mg respectively as a negative electrode. CONSTITUTION:For a negative electrode 2 of a zinc alkaline type cell, a zinc alloy containing Zn as the main component, 0.005-0.5wt% of In, 0.01-0.5wt% of Ni, and 0.05-0.2wt% of one or more of Ca, Sr, and Mg is used as an active substance. Ni has a less affinity with mercury and restricts the expansion of mercury into the crystals of the zinc alloy, resulting in maintaining a high mercury density over the surface of zinc alloy. In is an additive element for a high anticorrosion, while Ca, Sr, or Mg functions to smooth the surface of the zinc alloy powder. By combining adequate amounts of those elements for aditives, an anticorrosive zinc anode with a low mercurating rate is realized, and a zinc alkaline cell of excellent discharge and preservative properties with little environmental pollution can be obtained.

Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To obtain an indium oxide film having uniform film thickness and compsn. and excellent transparency with easy operation by using an aq. soln. containing indium ion and nitric acid ion. SOLUTION: As the ion source for both of indium ion and nitric acid ion. indium nitrate is preferably used. The indium ion concn. and the nitric acid ion concn. are preferably controlled to 0.0001 to 0.5 mol/l and 0.0001 to 1.0 mol/l, respectively. The indium oxide film is formed by dipping a base body for the formation of a film in an aq. soln. containing indium ion and nitric acid ion and electrolyzing while using the base body as a cathode. Any material can be used as the base body as far as it can be used for normal electroplating, and for example, a metal material, glass material, and plastic material can be used. By subjecting the indium oxide film thus formed to heat treatment at 100 to 800 deg.C, the crystallinity is improved to obtain higher electric conductivity and the adhesion property with the base body is further improved.

Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To reduce a ripple of an analog signal. SOLUTION: A timer counter 45 outputs a pulse width modulation signal with a pulse width in response to a setting value.
