A measuring unit measures an amount of a detected phase difference from an output of a vibration detection signal from a first detection electrode until an output of a vibration detection signal from a second detection electrode. The polyamide resin composition can have excellent heat resistance, reflectance, photostability andor discoloration resistance. A guitar in combination with the pickup unit is additionally provided. The method and apparatus provide a command set and logic that supports selective execution of particular commands directed at alive threads, whereby the command is performed only on resources andor execution units depending on the actual state of thread execution when the command operates within the processor. This on chip measurement capability supplies information that permits circuit engineers to design and fabricate on chip inductors to very tight tolerances.
