摘要:
The present invention relates to a polypropylene three-dimensional plexifilamentary fiber, a method of manufacturing same, and a nonwoven fabric composed of the above fiber.The plexifilamentary fiber in accordance with the present invention has a three-dimensional plexifilamentary structure, and is characterized in that the fiber has a microwave birefringence of 0.07 or more. As a result, a dimensional stability under heating of the plexifilamentary fiber in accordance with the present invention is extremely high. Moreover, it is possible to obtain a plexifilamentary fiber having a high spreadability by adding a spreading agent to the plexifilamentary fiber. A nonwoven fabric made of such plexifilamentary fiber has a high thermal dimensional stability, and as a result, the nonwoven fabric in accordance with the present can be usefully used in a wrapping material having a heat resistance and air permeability, apparel having heat resistance and moisture permeability, a heat resistance paper, and engineering and building materials or the like.
摘要:
A polypropylene three-dimensional plexifilamentary fiber having a microwave birefringence of 0.07 or more and an Mw/Mn of 4.3 or less. Although a spreading agent is not included in this fiber, the fiber has a superior fiber spreadability and dimensional stability. The fiber in accordance with the present invention can be spun from a dope composed of an isotactic polypropylene having an Mw/Mn of 4.3 or less and an MFR of 20 or less, and a halogenated hydrocarbon, by a flash spinning technique. Further, the present invention provides a spinning dope and a method of manufacturing the fiber which effectively prevent ozone layer destruction by using a 2,2-dichloro-1,1,1-trifluoroethane, a 1,2-dichlorotrifluoroethane or a solvent blended a dichloromethane with either of the above two solvents as the halogenated hydrocarbon.

An installer file, an application program file, and other such files are stored in image memory provided within a camera. Upon connection of the camera to a host device, programs within the installer file are read into the host device and automatically executed, and processing of user registration and installation processing of an attached application program contained within the application program file are automatically performed. After processing of program installation, the installer file and the application program file are deleted from the image memory.
摘要:
A camera system comprises a camera and a panoramic image synthesizing apparatus. The camera includes a photographing device for photographing an object, and a recording medium for storing divisional images of the object photographed by the photographing device and information relating to an angle of view of photographing. The panoramic image synthesizing apparatus performs a cylindrical conversion process based on the divisional images stored in the recording medium and the information relating to the angle of view, and synthesizing cylindrically converted images, thereby producing a panoramic image.

Namely, the reproducer is provided with a storage part for storing images, a vibration detection part for detecting a vibration operation by a user, a switching instruction part for instructing switching of reproduction content in slide show reproduction based on a detection result from the vibration detection part, a synthesis processing part for performing creation processing of slide show images, which are images for the slide show reproduction, based on instructions of the switching instruction part, and a slide show control part for performing the slide show reproduction of the images stored in the storage part and the slide show images.
摘要:
Image data obtained by photographing an object using a camera is stored in a storage medium that can be attached to and detached from the camera. The camera includes a device program storage unit and an information writing unit. A device program that can be executed by an information processing device, which is different to the camera, is stored in the device program storage unit. The information writing unit is constituted to be capable of writing the device program to the storage medium attached to the camera. While writing the device program to the storage medium, the information writing unit writes the device program in a format enabling the information processing device to read and execute the device program automatically when the storage medium is attached to the information processing device.
