The invention relates to a method for determining a separation, spacing or distance of an object from an ultrasonic sensor, in which ultrasonic pulses are emitted by a transducing or sensing element and in which ultrasonic pulses reflected by the object are detected by the same transducing element. Due to reduced fat contents and addition of soy protein with the plasma-cholesterol-suppressing property, the meat products of the invention can improve plasma lipids without reducing favorable texture and taste of the meat products. The face recognition section is implemented by a support vector machine that maps the result of face recognition to a non-linear space and that obtains a hyperplane that separates in that space to discriminate a face from a non-face. A container holds the lawn stencil, the container of paint, and the plurality of elongate members. The selectable elements correspond to user interactive features of the user interface and have a corresponding visual identifier. A carbide region including carbide of the target metal and a non-carbide region including the target metal are disposed in a mixed manner on a boundary surface between the substrate and the target layer on a target layer side.
