Patent number: 6626654Abstract: Foam forming techniques capable of permitting foaming of biodegradable resin to be positively and uniformly accomplished to provide a biodegradable resin foam with satisfactory quality. The biodegradable resin foam is made of biodegradable resin consisting of a main biodegradable resin ingredient of 100° C. or more in melting point and a low-melting biodegradable resin ingredient of 100° C. or less in melting point. The biodegradable resin foam is produced by placing a starting material consisting of at least biodegradable resin and a substantial amount of moisture in a heated and pressurized environment, releasing the starting material from the environment to foam the biodegradable resin, and subjecting the foamed resin to forming by means of a forming mold. An apparatus for producing the foamed biodegradable resin foam includes a pressure adjusting chamber, an air-permeable forming mold, a pressure reducing tank and an injection machine.Type: GrantFiled: May 8, 2001Date of Patent: September 30, 2003Assignee: Suzuki Sogyo Co., Ltd.Inventor: Motoyasu Nakanishi

Patent number: 6479136Abstract: An object is to provide a metal-clad laminated board applicable for a printed wiring board capable of readily dissipating heat and superior in thermal conduction, and further, the printed wiring board substrate overlaid with a lead frame having the same characteristics as the metal-clad laminated board. To attain the aforesaid object, the printed wiring board of the invention has the carbon-base substrate overlaid with metal foil or lead frame through an insulating bonding layer. Thus, in a case of using the metal foil, the printed wiring board is formed in a metal-clad laminated board, and in a case of using the lead frame, the printed wiring board is formed in a lead frame laminated board.Type: GrantFiled: May 4, 2001Date of Patent: November 12, 2002Assignee: Suzuki Sogyo Co., Ltd.Inventor: Motoyasu Nakanishi

Patent number: 5853854Abstract: A rugged shaped sheet capable of exhibiting improved non-slip properties and aesthetic properties and a process for manufacturing the same. The rugged shaped sheet includes a base sheet member and a rugged pattern of a predetermined shape adhered to the base sheet member. The rugged pattern is formed of a plurality of pattern elements different in size, configuration and/or properties into a multi-layer structure. The rugged shaped sheet is manufactured by pouring an elastomer liquid material into each of perforated plates, semicuring the elastomer and laminating the perforated plates on each other, resulting in forming the rugged pattern of a predetermined shape on the base sheet member.Type: GrantFiled: October 20, 1997Date of Patent: December 29, 1998Assignee: Suzuki Sogyo Co., Ltd.Inventors: Motoyasu Nakanishi, Akira Takayama
