An electroless plating pretreatment agent that can retain stably Pd over a long period of time in an organic solvent, an electroless plating method using the same that is capable of forming an electroless plated film having excellent adhesion, and an electroless plated object. A time maintenance system provides rules for converting dates and times between various time zones and a common time zone. Specifically, example business objects include DemandPlanningScenario, DemandPlanningScenarioTemplate, and DemandPlanningView. A spring arrangement with pressure pads is mounted directly on the mounting portion, and applies pressure to a top edge of a tape during guiding of the tape. In the electroplating step, the electroplate layer is electroplated on the external surface of the mark and the outer surface of the body except the preparing region with the printing layer to complete the metal hand tool. Releasing the locking mechanism on one or more extendable tip causes the extendable tip to move to the retracted position thereby relieving tension on a disposal bag that is supported in the support stand to avoid binding between the disposal bag and the posts.
