    摘要: A method for the production of a polymer from an aqueous solution of a corresponding .alpha., .beta.-ethylenically unsaturated monomer, which method is characterized by forwarding said aqueous monomer solution and an inert gas each in the form of a continuous flow toward the site of polymerization, spouting either of said two fluids through a nozzle parallelly into the flow of the other fluid thereby creating forced contact between said aqueous monomer solution and said inert gas and effecting substantial removal of dissolved oxygen from said aqueous monomer solution before said aqueous monomer solution reaches the site of polymerization.

    摘要: A touch panel input apparatus has a touch panel which consists of X- and Y-direction electrode panels. When the apparatus is in a power-off state, one end of the X electrode panel is intermittently connected to a power source and one end of the Y electrode panel is intermittently grounded via an output resistor, in response to control signals outputted from a sampling circuit. In this state, synchronously with a clock signal, the sampling circuit performs sampling of a voltage developed across the output resistor when the two electrode panels are brought into contact. The sampling circuit outputs a power-on instruction signal to make the CPU perform the power-on operation. The sampling circuit stops its sampling operation once power is turned on.
