Abstract: In accordance with an embodiment, an information processing apparatus includes a code reader, a memory, and a processor. The processor is configured to control the code reader to read a code attached to a package, determine whether the read code indicates a predetermined code assigned to a package containing a plurality of commodities, and when the read code indicates the predetermined code, retrieve from the memory information about the package indicating a total number of the commodities contained in the package, retrieve from the memory information about each of the commodities indicating a unit price of each of the commodities, and calculate sales based on the total number of the commodities and the unit price of each of the commodities.

Abstract: A variable resistance device in the form of a PIN diode is connected between one of a pair of input terminals and one of a pair of output terminals, and the other input and output terminals are connected to a common terminal.A distributed constant line is connected between the output terminal of the PIN diode and the common terminal, and variable capacitance diodes are connected between the opposite ends of the distributed constant line and the common terminal. By applying a control voltage applied to the PIN diode and the variable capacitance diodes, the steepness and the center frequency of the variable resistance device are varied.

Abstract: A control device which controls a plurality of controlled devices by time shared control in a microprogram control system and has one control memory, a plurality of microinstruction registers, the outputs of which are applied to the controlled devices, circuits for memorizing microinstruction execution requests corresponding to microinstruction type and the controlled devices, and a selecting circuit for selecting a microinstruction register for storing a microinstruction read out from said control memory in each machine cycle and the controlled devices to be controlled. The field of the microinstruction indicates the execution and type of the next microinstruction after the next machine cycle to a given controlled device.

Abstract: An amplitude limiter circuit utilizing two sets of seriesdiode limiter circuits is disclosed. Each diode circuit has a pair of diodes in series but in abutting polarity. An input signal is applied through a phase converter with equal amplitudes and in opposite phases to each other to the diode circuits and a bias current is applied to each pair of diodes. To obtain an output signal having its level variation suppressed the currents passing through the parallel capacitances of the diodes in each circuit are offset with each other thereby resulting in an output signal not being subject to a shift in response to the variation of the input signal level.
