  • Publication number: 20200378927
    Abstract: The present invention makes it possible for sounding of an inspection location on an outer wall of a building or the like to be performed using a simple operation. A user interface device accepts an input for designating an inspection location. The mobile robot device flies autonomously and moves to the inspection location, on the basis of the input into the user interface device and the current location of the mobile robot device. The mobile robot device inspects the inspection location using an inspection means such as a sounding means.

  • Patent number: 7786968
    Abstract: An output pulse of a flip flop is delayed in a delay inverter circuit before supplied to an input terminal of a level shifter. Then, an output pulse of the next stage flip flop is supplied to a reset terminal of the first flip flop and also to an enable terminal of the level shifter. Further, the level shifter output a sampling pulse with a beginning end equal to the beginning end of the pulse supplied to the input terminal and a terminal and equal to the beginning and of the pulse supplied to the enable terminal. With this arrangement, the subject invention provides a pulse output circuit, a driving circuit for a display device using the pulse output circuit, a display device and a pulse output method, that reduce delay of the terminal end of the pulse in sequentially outputting pulses from plural output terminals.

  • Patent number: 7652508
    Abstract: In one embodiment, a circuit device that performs a certain processing operation with respect to an input signal by referring to a reference voltage and outputs the result is caused to have a function of switching the reference voltage, whereby a circuit device from which a stable output can be obtained is disclosed. The circuit device includes a comparator and a reference voltage setting circuit. The comparator compares an input voltage fed from outside with a reference voltage selected from a reference voltage set including a plurality of voltage values that are different from one another.

  • Patent number: 6996203
    Abstract: The present invention includes: a shift register section, including multiple-stage flip-flops operating in synchronism with a clock signal, for switching a shift direction in accordance with an externally supplied direction instruct signal; a waveform change section for changing in waveform a signal output of one of the flip-flops which is in a first predetermined stage; and an inspection signal switching section for switching, in accordance with the direction instruct signal, an output between the signal output which has been changed in waveform in the waveform change section and a signal output of one of the flip-flops which is in a second predetermined stage.
