Abstract: A game in which a player is prevented from applying an excessive force to a button on a pressure sensitive controller. For a game device comprising a controller 32 for supplying one of digital values in a predetermined range in accordance with the force pressing of a button, the predetermined range includes a response range in which at least some of the digital values smaller than a predetermined threshold fall, and a response limit range in which the digital value at the predetermined threshold or greater falls. When a digital value supplied from the controller 32 falls in the response range, a response image changing in accordance with a change in the digital value is displayed. On the other hand, when the value falls in the response limit range, a response limit image whose change in accordance with the digital value is limited is displayed.

Abstract: The method disclosed here comprises the steps of (a) mixing metal powder, a resin, abrasive grains, and a solid reducing agent at the normal (room) temperature through the melting point of the reducing agent to form a mixture and (b) molding and baking the mixture at the melting point of the reducing agent through that of the metal powder. The solid reducing agent is a fatty acid, preferably stearic acid having a volume ratio of 5 to 20% with respect to the metal powder. With is, it is possible to make metal-resin bond grindstones that give such high-quality mirror surfaces that have conductivity fit for ELID grinding and are not liable to have chippings or scratches and also have an Rmax value of approximately 3 nm or less.
