Patent number: 7841854Abstract: A temperature adjustment mechanism for use in an injection molding machine that shortens a molding cycle time while preventing the occurrence of a stranding phenomenon in an optimum manner. A passage includes an opening arranged near an outer surface of an outlet of an injection nozzle for an injection molding machine. A supply control unit supplies the passage with at least one of cooling air and heating air to selectively eject the cooling medium, the heating medium, and a mixture of the cooling medium and the heating medium near the outer surface of the outlet.Type: GrantFiled: November 20, 2006Date of Patent: November 30, 2010Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Masaya Ota, Haruo Yokohama, Yasuji Tanaka, Yasuo Hirakawa, Shinichiro Sekido

Patent number: 5861217Abstract: Disclosed are a composite material having an anti-wear property and a process for producing the same. The composite material includes a matrix of a low melting point Sn alloy having a melting point of from 80.degree. to 280.degree. C., and metallic dispersing particles dispersed in the matrix in an amount of from 10 to 50% by volume. When the composite material is utilized to make a rough mold for preparing a prototype, it sharply improves the anti-wear property of the rough mold, and it can be re-used for a plurality of times without adversely affecting the sharply improved anti-wear property. The composite material provides the advantages effect best when the metallic dispersing particles are Fe-C alloy dispersing particles and/or Fe-W-C alloy dispersing particles which were subjected to a surface treatment including an Sn or Ni electroplating followed by a ZnCl.sub.2 .cndot.NH.sub.4 Cl flux depositing.Type: GrantFiled: November 8, 1996Date of Patent: January 19, 1999Assignees: Toyota Jidosha Kabushiki Kaisha, Nisshin Steel, Co., Ltd.Inventors: Satoru Kito, Masahito Ito, Fuminori Matuda, Eiki Takeshima, Yasuji Tanaka, Takahiro Fujii, Kenjiro Izutani

Patent number: 5112454Abstract: The electromotive force of a standard liquid for correction is measured. Both before and after this measurement, the electromotive force of a reference liquid is measured at least once. A calibration curve is prepared based on the resultant data. The calibration curve is used to convert the electromotive force difference between a test liquid (the ion concentration of which is to be measured) and the reference liquid. Both before and after the measurement of the electromotive force of the test liquid, the electromotive force of the reference liquid is measured at least once. By so doing, the electromotive force difference between the test liquid and the reference liquid is obtained. The ion concentration of the test liquid can be detected accurately by plotting the electromotive force difference against the calibration curve.Type: GrantFiled: February 16, 1990Date of Patent: May 12, 1992Assignee: Kabushiki Kaisha ToshibaInventors: Yasuji Tanaka, Akiko Tanaka
