摘要： In a voltage detecting circuit, a transistor is configured as a P-type MOSFET, and includes a source connected with an input terminal, a gate connected with a ground voltage terminal and a drain connected with an output terminal. A transistor is configured as a P-type MOSFET, and includes a gate and a source connected with the output terminal and a drain connected with the ground terminal. Gate width and gate length of the transistor and gate width and gate length of the transistor are adjusted so that source-drain current flowing between the source and the drain of the transistor becomes equal to source-drain current flowing between the source and the drain of the transistor when the voltage applied to the input terminal is set to be preset trigger voltage. This configuration accomplishes detecting that the input voltage exceeds the trigger voltage with simple configuration.

摘要： The channel number detecting circuit detects the operation channel number based on the output terminal voltage after falling down when the output terminal voltage falls down during the voltage boosting control, and the switching control circuit generates the control clock signal having the on-time and the off-time adjusted based on the operation channel number and performs the voltage boosting control using generating control clock signal. The voltage boosting control is properly performed based on the operation channel number when the operation channel number increase during performing the voltage boosting control. Thus boosting the power supply voltage up to a second voltage is accomplished.

摘要： An optical displacement measuring apparatus including an afocal optical system within a plane containing paths of at least two light beams. The afocal optical system includes a first lens optical unit and a second lens optical unit having a focal length which is greater than the focal length of the first lens optical unit. The distance between a diffraction grating and the first lens optical unit is smaller than the focal length of the first lens optical unit. The second lens optical unit is a combination of a lens with a negative refractive power and a lens with a positive refractive power. Accordingly, the optical displacement measuring apparatus performs accurate measurements with a large measurement depth, even for the cases where an afocal optical system is constructed within a plane containing the paths of the two light beams and the working distance is increased without increasing the size of an optical head.
