A light emitting element has a semiconductor layer, a pair of positive and negative electrodes, and a reinforcing portion. The first and second panel segments extend in opposite directions from the web formation and the sheet further comprises a lip formation extending generally transversely from the first panel segment at an end defined by the said panel segment distal to the web formation and extending in a direction towards the plane wherein the second panel segment is located. Thus, even if any resolver is in trouble, the steering angle can be detected continuously and by maintaining the functions of ABS, VSC and the like, the safety in traveling can be intensified. And, a mobile station within a femtocell is able to perform reliable communications. The cutting mechanism includes a blanking hole communicating with the basket in the case. The invention enables the combining of a plurality of integrated microchannel devices to provide the benefits of large-scale operation.
