A first groove portion into which a first plug connector can fit and a second groove portion that surrounds the first groove portion and into which a second plug connector can fit are formed in a receptacle connector. Prior to alignment of a mask with a wafer, the asymmetry of each alignment mark is measured according to the principle of a scatterometry, and the alignment is performed in consideration of the result of measurement to execute exposure. Otherwise, while the content of the special instruction has been stored in a management server, an operation may be carried out in response to the instructed response after the remaining battery power amount has been recovered to a sufficiently high battery power amount. The external module is configured to temporarily generate electrical stimuli that are delivered by at least one of the first and second leads to provide therapy cardiac resynchronization therapy to the heart. The semiconductor integrated circuit device secures a sufficient delay time with a small area.
