Title: Bedding
Inventor: MIYAUCHI TATSUO
IPC: A47C27/00
Filed: 2001-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a warmer, flexible, thin, and light bedding having a fabric to which the characteristics of a metal having a high heat-storing property is added. SOLUTION: This bedding has a fabric which comprises a metal layer adhered by a spattering method and a substrate layer comprising a fabric. Thereby, the thin film of the metal is tightly adhered to the fibers of the fabric, and the fibers therefore have a high heat-storing effect because of absorbing heat rays emitted from the body of a user due to an IR light-absorbing function. Hence, even a thin fabric can have a sufficient heat-insulating effect. Since the metal is tightly adhered by the spattering method, characteristics comprising a high adhesion strength and easy processability due to the unchanged flexibility of the fibers are obtained.

Title: Bus system
Inventor: OSAKA HIDEKI
IPC: G06F13/16
Filed: 2001-07-04
Abstract: PROBLEM TO BE SOLVED: To make the intervals between memory modules narrow since a certain interval is necessary as the efficiency of transmission, i.e., the degree of coupling, and should not be less than the wiring length that a directional coupler occupies although bus-connected module intervals are determined by the wiring length. SOLUTION: Since a wire (main line) from a memory controller is made to have open ends or short-circuit ends and signals can be generated in both the directions of the directional coupler by using a progressive wave and a reflected wave, DRAMs can be connected to both the sides of the coupler. Consequently, the wiring length of the coupler is reducible to a half of the pitch between modules, so that high-density mounting becomes possible.
