    摘要: An iris authentication apparatus includes an iris area extraction unit, registration pattern generating unit, collation pattern generating unit, and collation unit. The iris area extraction unit extracts iris areas from a sensed registration eyeball image and a sensed collation eyeball image. When the iris area extraction unit extracts an iris area from the registration eyeball image, the registration pattern generating unit generates a registration iris pattern image by performing polar coordinate transformation of an image in the extracted iris area. When the iris area extraction unit extracts an iris area from the collation eyeball image, the collation pattern generating unit generates a collation iris pattern image by performing polar coordinate transformation of an image in the extracted iris area. The collation unit collates the registration iris pattern image output from the registration pattern generating unit and the collation iris pattern image output from the collation pattern generating unit on the basis of a correlation therebetween.

    摘要: A switching DC-DC converter includes: an output voltage detecting unit configured to detect a DC output voltage; an error amplifying unit configured to compare the detected output voltage and a reference voltage and configured to supply an amplified error signal between the detected output voltage and the reference voltage to the pulse width modulating unit; and a single oscillating unit connected to an output of the output voltage detecting unit and an output of the error amplifying unit and operable on a first oscillating mode and a second oscillation mode. The oscillating unit on the first oscillating mode controls a switching frequency of the power switch based on the detected output voltage. The oscillating unit on the second oscillating mode controls the switching frequency of the power switch based on the amplified error signal.

    摘要: A method of manufacturing a plugged honeycomb structure has a plugging process which includes the steps of: immersing one end (a first end) of a honeycomb base material in a plugging slurry while vibrating the plugging slurry; after bringing an internal part of a cell into a negative pressure and then returning it into an atmospheric pressure, vibrating the plugging slurry to make the plugging slurry enter a first open end of the cell; and drying the plugging slurry having entered the first open end of the cell to form a first plugging portion at the first end.
