An instrument kit for reaming a cavity within a resected head of a bone is provided. The punch tip consists of an appropriate number of long forming punch tips each including a press forming portion in the leading end thereof. As a result, even if the voltage controlled oscillator 8 that operates by following the frequency of an input clock has changed into an operation stop state, because the output fixing units 31 fix the outputs of the variable delay circuits 30, the output of the voltage controlled oscillator 8 is prevented from being in an inconstant state. The propelled-object-side equipment transmits an inquiry signal to the portable equipment in response to an actuation signal of the switch, and the portable equipment transmits an answer signal corresponding to the inquiry signal. The present invention relates further to units which could be used in a spinning multifunctional module, and use of a spinning multifunctional module. Related methods, and certificates produced by the various methods, are also described.
