A clock generator circuit provides an output clock without an abnormal waveform pulse which causes faulty operation in other function circuits. The cells are side population cell separated from human amniotic mesenchymal cell layer, in which expressions of Oct-4 gene, Sox-2 gene and Rex-1 gene are observed by RT-PCR, and which are vimentin-positive and CK19-positive in immunocytostaining. The pan-handle holder comprises an insulating sleeve having a sleeve axis with first and second complimentary sections and a lumen, which allows for closely receiving a pan-handle. The laminated wiring board offers a high degree of mounting reliability even when it is interposed between the electric device such as a silicon semiconductor device having a small coefficient of thermal expansion and an external circuit board such as a printed board having a large coefficient of thermal expansion. Furthermore, the apparatus transmits information based on the interferer backoff information in one of an RTS message or a CTS message to the second wireless device. The device consists of two conductive plates sandwiching a conductive grid, typically embedded within a dielectric material.
