    摘要: A substantially water-free, emulsion type liquid lubricant for metal forming which comprises:(a) a lubricating oil,(b) at least one of phosphoric acid esters represented by the general formula: ##STR1## wherein R is alkyl, alkylalkenyl or aryl; n is an integer of 1 to 2, and (c) an emulsifying agent,an average particle size of the phosphoric acid ester being 0.3 to 120 .mu.m, can form a lubricating film having distinguished heat resistance and lubricating properties by virtue of the heat generated by deformation and friction during the metal forming only by wetting the surface of a metallic workpiece or a die or both with the lubricant and work effectively for preventing galling, and thus parts with a high reduction of area or parts of complicated shapes can be readily formed.A lubricating film having a lubricating effect equivalent to that of the conventional phasphate film can be simply obtained, greatly contributing to reduction in product cost.An emulsion type liquid lubricant having a prolonged emulsion stability can be prepared through emulsification with a high speed mixer having a stirring blade with wiremesh-like fine perforations, and thus articles or parts with uniform quality can be formed.

    摘要: A delay circuit includes a delay unit having a first and a second power supply terminals, a pair of differential signal input terminals and a pair of differential signal output terminals. The signals entered to the pair of differential signal input terminals are delayed and output at the pair of differential signal output terminals. The delay circuit also includes a current controller that exercises control to cause a current of a current source, controlled by a current control terminal, to flow through the first and second power supply terminals of the delay unit. The delay circuit also includes a voltage controller that exercises control to provide for a constant potential difference between the first and the second power supply terminals (FIG. 1).

    摘要: A pleochroic color display device is provided which comprises a layer of guest-host type liquid crystal sandwiched between two transparent electrodes for driving the liquid crystal, the guest-host liquid crystal containing a dichroic dye as guest material, and a color filter disposed in front or rear of the layer of the guest-host type liquid crystal. High contrast pleochroic color displays can be obtained by selecting a blackish dye as the dichroic dye. Dichroic displays other than white ones can be produced by the use of a single liquid crystal cell and a single color filter (with one color).
