Publication number: 20110113644Abstract: [Object] To provide a freeze-drying apparatus and a freeze-drying method, which are capable of increasing a collection rate of a raw material without a need for providing a member such as a baffle plate or the like. [Solving Means] The freeze-drying apparatus 100 includes: a container 4 to store a raw material fluid F; a freezing chamber 10 being a vacuum chamber; a vacuum pump 1 to exhaust the freezing chamber 10; and an injection mechanism 25 to inject the raw material fluid F stored in the container 4 into the freezing chamber 10. The cold trap 20 is arranged within the freezing chamber 10, and hence a phenomenon that the raw material is discharged to the outside of the vacuum chamber together with a vapor as in the past can be prevented. With this, the collection rate of the raw material can be increased. Further, it becomes unnecessary to provide the baffle plate or the like for preventing the phenomenon in vicinity of an exhaust port of the vacuum chamber.Type: ApplicationFiled: July 8, 2009Publication date: May 19, 2011Applicant: ULVAC, INC.Inventors: Masaki Itou, Kyuzo Nakamura, Takeo Kato, Katsuhiko Itou, Takao Kinoshita

Patent number: 6328313Abstract: A gasket comprises a thin plate to be arranged between confronting surfaces of a cylinder block and a cylinder head. The thin plate has attached with adhesives susceptible to plastic deformation at areas where the thin plate comes in mating with the confronting surfaces. The adhesives come in adhesion with the confronting surfaces to restrain relative displacement that might occur constantly between the mating surfaces of the plate and the confronting surfaces. This contributes to keeping the gasket stiff. The adhesives of plastic deformation property are arranged along peripheries of cylinder bore holes at the areas where the thin plate comes in mating with the confronting surfaces. The adhesives, when have come in adhesion with the confronting surfaces, not only establish the reliable head-to-block sealing, but also restrain the displacement that might occurs constantly between the mating surfaces, in favor of plastic deformation of the adhesives.Type: GrantFiled: November 1, 1999Date of Patent: December 11, 2001Assignee: Nippon Gasket Co., Ltd.Inventors: Minoru Teranishi, Takao Kinoshita
