Patent number: 8293828Abstract: The present invention relates to using an adhesive and process for heating, curing, joining, attaching and detaching a part article from a body substrate structure. Described are polymeric adhesive compositions and methods of curing using a radiation apparatus for rapid adhesive bonding and attaching a fastener part to a structure surface. The adhesive composition contains additives that directly or indirectly absorb projected radiation from a radiation apparatus to rapidly and uniformly melt the adhesive and bond the surface of the part material onto the surface of the substrate material. A process is also described to reverse the adhesive bonding and detach the fastener part from the substrate.Type: GrantFiled: January 17, 2008Date of Patent: October 23, 2012Assignee: Kubota Research Associates, Inc.Inventors: Masanori Kubota, Ayako Kubota, Munetaka Kubota, Takuma Kubota

Publication number: 20120148753Abstract: The present invention relates to a prepreg composite and to a process for manufacturing the prepreg composite. The manufacturing process involves surface treatment and impregnation of a high tenacity fibrous material with a surface treatment agent and a polymer matrix resin material. The fiber may be in the form of a woven, unidirectional or non-woven fabric. The fiber may optionally be coated with a surfactant and/or an adhesion promoter. Prior to treatment, the surface treatment materials may be contained in a dispersion of nano-particles in which each material has a film forming process temperature at a value below the degradation temperature of the fiber. The layers may be applied individually or simultaneously onto the fibers. The coated material is heat dried without compression to form a prepreg composite.Type: ApplicationFiled: February 5, 2008Publication date: June 14, 2012Inventors: Masanori Kubota, Ayako Kubota, Munetaka Kubota, Alexander Kubota

Publication number: 20120061013Abstract: The present invention relates to a composite article and to a process for manufacturing the composite article. The composite article comprises multiple layers including high tenacity fibers incorporated into a fabric and a core thermoplastic resin. The fabric may be coated with a surface treatment agent and a polymer matrix resin. Single or multiple layers of the composite articles may be formed into a composite part having high strength, rigidity, fast molding cycle time and extremely good conformability in a 3-dimensional mold. The composite parts formed by this process have high part strength in all directions.Type: ApplicationFiled: September 23, 2011Publication date: March 15, 2012Inventors: Masanori Kubota, Ayako Kubota, Munetaka Kubota, Alexander Kubota

Publication number: 20060283543Abstract: A process for heating a polymeric material throughout its thickness using infrared electromagnetic radiation, whereby there is dispersed in the polymeric material throughout its thickness an infrared radiation absorbing agent in an amount such that at least a portion of the infrared radiation incident on the material from one side exits from the opposite side. The absorbed radiation may selectably vary from 1% to 99%; the particular percentage is calculated to rapidly heat the material to a temperature that depends on a particular application, and may be sufficient to soften the material so it can be pressure formed into a desired shape or, alternatively, high enough to melt this material when placed between two surfaces and used to the two surfaces together.Type: ApplicationFiled: August 29, 2005Publication date: December 21, 2006Inventors: Masanori Kubota, Ayako Kubota, Munetaka Kubota, Alexander Kubota

Patent number: 4112690Abstract: Subjacent and lateral supporting soil for an underground tank is stabilized wherein a tank embedded therein is secured against flotation irrespective of the water table level of the surrounding soil. The lateral supporting soil is encased within a well and the subjacent soil is hardened to minimize seepage of water into the soil adjacent to the tank. Means are also provided to remove excess water from the confines of the well thereby minimizing flotation pressure on the tank.Type: GrantFiled: November 15, 1976Date of Patent: September 12, 1978Assignee: Kajima Kensetsu Kabushiki KaishaInventors: Kazuo Hosoya, Munetaka Kubota

Patent number: 4094151Abstract: The ground surrounding a liquified gas storing underground tank is excavated into a form of a columnar cavity or wall shaped cavity, and then a synthetic resin bag or envelope is placed therein, after which granular materials such as sand or gravel is filled therein, thus forming a water permeable body of a columnar shape or wall-like shape. Then, water is injected into the water permeable body from its bottom and then discharged from the top of the body, thereby warming the peripheral ground of the underground tank for preventing freezing thereof. An apparatus for preventing the freezing of a liquified gas storing underground tank is also disclosed, which includes water feeding and discharging devices provided for the aforesaid water permeable body.Type: GrantFiled: April 19, 1977Date of Patent: June 13, 1978Assignee: Kajima Kensetsu Kabushiki KaishaInventors: Hiroshi Fujita, Munetaka Kubota, Takashi Makita, Yukishige Takahashi
