Disc-shaped storage medium provided with identification means to distinguish CD from the other storage medium such as CD-ROM, wherein the identification means comprise raised letters, depressions, projections or a selective combination of thereof formed on a top surface of a substrate so as to be sensed as user touch them with the finger tip. The process works at the milder reaction conditions and utilizes inexpensive catalysts that can be recycled several times. The transmit circuit is configured to generate a blocking signal having a frequency used by the card reader to communicate with the contactless smartcard. In addition, the entire link rod can be positioned inside the interior of the outer shell, and the pivot axis of the lid about the outer shell can also positioned inside the interior of the outer shell. The composition may also include an extracellular matrix scaffold component of any formulation, and further include added cells, proteins, or other components to optimize the regenerative process and restore cardiac function. An output of a drive motor is input to the output shaft by changing the speed into two-step decelerated rotation by means of an automatic transmission.
