Title: Production of asphalt foam
Inventor: KUMASAKA SADAO
IPC: C08J9/08
Filed: 1982-06-03
Abstract: PURPOSE:To obtain an asphalt foam free of nonuniformity and degradation of quality, by mixing an aqueous asphalt emulsion with a specified urethane prepolymer and foaming the mixture. CONSTITUTION:100pts.wt. aqueous asphalt emulsion is mixed with 40-250pts.wt. urethane prepolymer obtained by reacting a polyether-polyol, >=15% ethylene oxide content, with an organic isocyanate, and the mixture is foamed. In the above aqueous asphalt emulsion, the ratio of asphalt to water is such that 1pt.wt. asphalt is present per 0.3-2.0pts.wt. water. As is different from a case of a conventional asphalt foam, which is prepared by impregnating a synthetic resin foam with asphalt, separation of asphalt from the foam base does not occur because the asphalt itself constitutes the foam in case of the asphalt foam obtained by the present process.

Title: Photocurrent amplifying circuit
Inventor: MATSUYAMA EIICHI
IPC: H04B10/293
Filed: 1982-06-01
Abstract: PURPOSE:To secure the linearity of a signal during a high-contrast period, to secure the linearity even in a high-contrast period, and to facilitates the processing of the signal by making a high-contrast gain greater than a low-contrast gain. CONSTITUTION:The quantities of input light are converted into currents by photodetectors D1 and D2 and those currents are converted by converting circuits A11 and A12 into voltages. In case of low contrast, namely, when the absolute value of the difference in output voltage between converting circuits A11 and A12 is less than a reference set voltage difference DELTAVd, the outputs of voltage comparators C1 and C2 are both low. The outputs of the voltage comparators C1 and C2 are ORed by an OR circuit, whose output is low, obtaining the gain R21/R11 (R11=R12 and R21=R22) of an operational amplifying circuit A2. In case of high contrast, namely, said absolute value is greater than the reference set voltage DELTAVd, the output of the OR circuit is high. In this case, the gain is R31/ R11 (R11=R12 and R31=R32). By selecting R21/R11>R31/R11, the gradient of the output is increased when the contrast is low and decreased when high.

Abstract: PURPOSE:To erase the character width of an underlined type by detecting underline data at the present position of a print head, a printing position disposed at the upper or lower position by one, and erasing the underline of the present position without finely moving the head. CONSTITUTION:A main CPU 39 prints a character/symbol corresponding to data input from each character key 10 by a printing mechanism PM on the basis of a control program, and sequentially stores printing data corresponding to printing positions in a printing data memory 52.
