Patent number: 6809916Abstract: A shock absorbing body is interposed between an internal component such as a hard disk drive (HDD) and the inside surface of an enclosure for an electronic apparatus such as a notebook personal computer. The shock absorbing body includes a first receiving surface defined at one end of the shock absorbing body so as to receive the internal component. A second receiving surface is defined at the other end of the shock absorbing body so as to receive the inside surface of the enclosure. A constriction is formed in the shock absorbing body between the first and second receiving surfaces. When a larger impact is applied to the enclosure, the shock absorbing body is allowed to suffer from a fracture at the constriction. The energy of the impact is transformed into the energy of the fracture at the constriction. The impact energy is sufficiently consumed in this manner. The internal component can be protected from the larger impact.Type: GrantFiled: January 30, 2001Date of Patent: October 26, 2004Assignee: Fujitsu LimitedInventors: Katsuhiko Nakata, Tadanobu Matsumura, Shinichirou Kouno

Publication number: 20040166934Abstract: An object interaction expression apparatus for expressing interactions between plural objects that move by simulation in a virtual space is provided. The apparatus includes an expression mode storing unit, an interaction magnitude calculating unit and an expression controller. The expression mode storing unit stores in a correlated form an interaction magnitude of an object and a corresponding expression mode in which the interaction magnitude will be expressed. The interaction magnitude calculating unit calculates interaction magnitudes of objects that interact with each other. The expression controller controls an expression of the interaction magnitude of the objects that interact with each other based on the expression modes stored corresponding to the interaction magnitude calculated.Type: ApplicationFiled: February 10, 2004Publication date: August 26, 2004Applicant: Fujitsu LimitedInventors: Katsuhiko Nakata, Yukari Sato
