Patent number: 6194650Abstract: A coated material comprising a substrate which has micropores and a reaction product coated thereon along the surface configuration of the substrate and an inner wall of the micropores thereof. The coated material is preferably produced by performing a supercritical coating step wherein a reaction precursor is dissolved in a supercritical fluid to form a precursor fluid and then the precursor fluid is brought into contact with a substrate in the presence with a reaction initiator to allow a reaction between the reaction precursor and the reaction initiator, thereby coating a reaction product onto the substrate.Type: GrantFiled: April 27, 1999Date of Patent: February 27, 2001Assignee: Kabushiki Kaisha Toyota Chuo KenkyushoInventors: Hiroaki Wakayama, Yoshiaki Fukushima, Narihito Tatsuda, Yoshitsugu Kojima, Osami Kamigaito, Yasutomo Goto, Shinji Inagaki, Kenichirou Suzuki, Megumi Sasaki, Hiroaki Hayashi, Kazuo Higuchi, Norihiko Setoyama

Patent number: 6090862Abstract: A process is developed for recycling a polyolefin cross-linked substance having a cross-linkage, a polyolefin foamed substance free from a cross-linkage or a polyolefin foamed substance having a cross-linkage. The process includes the step of heating the polyolefin cross-linked substance together with a cross-linkage breaking agent, whereby breaking the cross-linkage to recycle the polyolefin cross-linked substance into a moldable thermoplastic resin. Further, the process includes the step of adding a foaming-agent-decomposition facilitating agent to the polyolefin foamed substance in the course of thermally melting the polyolefin foamed substance, whereby decomposing a residual foaming agent remaining in the polyolefin foamed substance.Type: GrantFiled: September 11, 1997Date of Patent: July 18, 2000Assignee: Toyota Jidosha Kabushiki KaishaInventors: Narihito Tatsuda, Kenzo Fukumori, Norio Sato, Seiichi Sahara, Hideki Ono

Patent number: 5811036Abstract: A process for recycling a thermoplastic resin covered with a thermosetting-resin paint film includes the steps of decomposing the paint film by bringing the thermoplastic resin covered with the paint film into contact with a paint-film-decomposing agent in a molten state, and removing decomposed products, resulting from the paint film and the paint-film-decomposing agent, and the residual paint-film-decomposing agent by degassification to prepare a recycled resin. The paint-film-decomposing agent can be primary amines and/or secondary amines having a boiling point of 250.degree. C. or less, or being decomposed at 250.degree. C. or less, or can be tertiary amines and/or quaternary amines having a boiling point of 250.degree. C. or less, or being decomposed at 250.degree. C. or less to which water and/or alcohols is added.Type: GrantFiled: April 26, 1996Date of Patent: September 22, 1998Assignees: Toyota Jidosha Kabushiki Kaisha, Kabushiki Kaisha Toyota Chuo KenkyushoInventors: Naoyuki Takahashi, Sadao Ikeda, Yoshio Taguchi, Narihito Tatsuda, Norio Sato, Kenzo Fukumori

Patent number: 5710273Abstract: A complex crystal is composed of anion of triiodine and cation of a fused compound consisting essentially of at least one nitrogen atom and at least 3 aromatic fused rings. Since the complex crystal has such a stable structure, it shows excellent heat resistance and excellent moisture resisting property. Furthermore, the complex crystal has light-polarizing performance because of an arrangement of the molecular chain of iodine. Moreover, the complex crystal exhibits excellent polarization because of an interaction between the fused compound and iodine. Therefore, the complex crystal is suitable for use as light-adjusting particles of a light valve or a light-adjusting glass.Type: GrantFiled: July 25, 1996Date of Patent: January 20, 1998Assignees: Toyota Jidosha Kabushiki Kaisha, Kabushiki Kaisha Toyota Chuo KenkyushoInventors: Arimitsu Usuki, Hisato Takeuchi, Narihito Tatsuda, Akane Okada, Toshio Kurauchi, Hiromitsu Tanaka, Shinobu Okayama, Kazuo Tojima, Akio Fukui, Toshiro Okamoto

Patent number: 5368780Abstract: A herapathite has a capillary crystal form in which its iodine atoms are oriented in a major axis direction of the capillary crystal form. The herapathite obtained is expressed by a chemical formula, xC.sub.20 H.sub.24 N.sub.2 O.sub.2.yH.sub.2 SO.sub.4.zHI.sub.3, in which a ratio of a number of the sulfuric acid molecules (y) with respect to a number of the iodine atoms (3z), i.e., (y/3z), is less than 0.5. The production process includes a reaction step, a first separating step, a recrystallizing step and a second separating step. A solvent used in the recrystallizing step is at least one of water and alcohol. A mixing weight ratio of water with respect to alcohol of the solvent is more than 50/50 or less than 10/90. The herapathite does not degrade even after it is heated up to 130.degree. C., and it is applicable to an automobile light shielding glass which should show a high transparency when a voltage is applied thereto.Type: GrantFiled: November 14, 1991Date of Patent: November 29, 1994Assignees: Toyota Jidosha Kabushiki Kaisha, Kabushiki Kaisha Toyota Chuo KenkyushoInventors: Kazuo Tojima, Shinobu Okayama, Arimitsu Usuki, Narihito Tatsuda, Kazuhisa Yano, Hisato Takeuchi
