    摘要: An overlaying alloy containing no Cr or a reduced amount of Cr, in which an effective amount of Mo oxide is formed even in a weak oxidizing atmosphere such as a combustion atmosphere of diesel engines and engines using CNG, LPG or other gases as a fuel to provide an improved non-damaging property and wear resistance. An overlaying alloy comprising 20-70 wt % Mo, 0.5-3 wt % C, 5-40 wt % Ni, and the balance being Fe and unavoidable impurities, which contains no Cr to facilitate formation of Mo oxide and is advantageously applied to the parts on which an oxide coating is not easily formed such as the engine parts subject to a lower temperature combustion atmosphere. An overlaying alloy comprising 20-60 wt % Mo, 0.2-3 wt % C, 5-40 wt % Ni, 0.1-10 wt % Cr, and the balance of Fe and unavoidable impurities, which contains a small amount of Cr to control formation of Mo oxide and is advantageously applied to the parts on which an oxide coating is relatively easily formed. Other alloying elements such as Mn, Co, Si, Nb may be added in the alloy in accordance with need.

    摘要: Disclosed herein are a liquid crystal composition which has a low viscosity and exhibits a high response speed while keeping the characteristic properties (e.g., orientation and switching performance) required of liquid crystal materials, a liquid crystal element based on said liquid crystal composition, and a process for producing said liquid crystal composition. The liquid crystal composition contains a clathrate compound of liquid crystal molecules with cyclodextrin or a derivative thereof. The clathrate compound functions to increase the free volume of liquid crystal molecules. The liquid crystal composition is prepared by dissolving in a solvent a liquid crystal and cyclodextrin (or a derivative thereof), thereby forming a clathrate compound and adding this clathrate compound to a base liquid crystal material.

The electrochromic material layer is composed of leuco dyes, supporting electrolyte and binder. The leuco dyes can be colored and discolored upon application of current thereto in a liquefied state of the material layer. Melting the material layer and application of current are carried out by the array of the electrodes.
