The present invention relates to disposable absorbent articles such as diapers and sanitary napkins which are provided with adhesives for attachment of the article to the skin which adhesives provide secure attachment and are pleasing to the skin upon application, yet cause no discomfort upon removal. In certain embodiments an energy source is applied to the limb to facilitate intermittent compression treatment. It is therefore possible for the CPU to perform appropriate display control according to the lighting state when an interrupt event occurs. The apparatus may also comprise one or more hydrogen-absorbing materials placed in a flow path of the feed material, to prevent at least one portion of hydrogen-containing molecular fragments in the feed material from entering the ion source chamber. The fuel injector may be located within the fuel injector opening. The image forming system also includes a swath adjustment module to dynamically adjust a swath size of a respective swath.
