Abstract: A control system includes a contact sensor configured to detect contact between an operation body and a door handle, a force sensor configured to detect a force applied by the operation body to the door handle, and a controller configured to control opening or closing of a door when the contact is detected by the contact sensor and the force is detected by the force sensor.

Abstract: A delay time is set only within the variable delay time of a clock driver and cannot be set longer than the variable delay time of the clock driver. A control circuit adjusts the delay amount of a variable delay circuit so as to synchronize a pulse phase after a first pulse outputted from a pulse generation circuit passes through the variable delay circuit N times and a second pulse outputted from the pulse generation circuit.

Abstract: A phase comparison circuit detects a phase difference between a data signal and the output from a variable delay circuit. A Code Operator detects a value of a control code corresponding to a delay equal to one period of an output clock. Then, when a delay amount of the variable delay circuit exceeds one period of a clock during synchronization of the output clock with the data signal while the control code is changed in accordance with the detection result by the phase delay circuit, a control code corresponding to a delay equal to one period of the output clock is added or subtracted to/from the control code at a time. Therefore, even if there is a difference in frequency between a data signal and a clock, it becomes possible to synchronize the data signal and the clock with application of the same clock phase.

Abstract: PD detects a phase difference between DATA and VDL output from VDL. Code Operator detects a value of a control code corresponding to a delay equal to one period of an output clock. Then, when a delay amount of VDL exceeds one period of a clock during synchronization of the output clock with the data signal while the control code is changed in accordance with the detection result by PD, a control code corresponding to a delay equal to one period of the output clock is added or subtracted to/from the control code at a time. Therefore, even if there is a difference in frequency between a data signal and a clock, it becomes possible to synchronize the data signal and the clock with application of the same clock phase.
