Abstract: A portable terminal 1 having a battery 11 obtains a congestion level indicating people-related congestion in a range including a point where a specific function of the portable terminal 1 is expected to be executed. Based on the congestion level, the portable terminal 1 performs a reduction process for reducing power consumption of the battery 11 before arriving at the above point, where the specific function is expected to be executed.

Abstract: In an electronic book system 1 distributing electronic books to browsing devices 30A, 30B, and 30C via a communication network 50, the acquirer of a distribution server 20 acquires the context of operation by a first user who is provided with first candidate pages contained in an electronic book in a previewable manner. The designator of the distribution server 20 designates second candidate pages based on the context of operation acquired by the acquirer and the first candidate pages. The provider provides the second candidate pages designated by the designator to a second user in a previewable manner.

Abstract: Provided are an evaluation device, an evaluation method, and an evaluation program for further accurately evaluating the magnitude of effect of each page in an electronic book on getting users interested, and also a computer-readable recording medium recording the program. With a book server 100, a start page is identified first and a display amount of each page is counted. The display amount counted is weighted for each page by using weight coefficients determined by a coefficient storage unit 2. For page 7 displayed five times, the display amount is weighted with 1.6, 1.6, 0.9, 1.1, and 0.9 for the respective times. The total amount of the display amount of each page thus weighted is calculated. For page 7, the total amount of the display amount for each page is calculated as 6.1 points.

Abstract: This invention relates to a tubular stretching method for producing a stretched film by passing a tubular thermoplastic resin film between pairs of nip rolls having mutually different peripheral speeds and by inflating the tubular film with internal pressure under heating and a stretching apparatus to be employed therefor. The pairs of nip rolls include at least three pairs of nip rolls. Pressurized air is admitted into a stretched bubble situated between the first and second rolls through a slit-like air injecting nozzle, and the bubble formed by the supplied pressurized air is inflated and stretched under heating. In this stage, if desired, the amount of injected pressurized air is controlled by manual or automatic control by detecting the diameter of the bubble so as to keep the bubble's diameter constant. After stretching, the tubular film is collapsed and is introduced to the second nip rolls. Both side ends of the collapsed film are cut open with film cutting knives to make two sheets of flat films.

Abstract: A process for producing a porous resin film containing a polyolefin resin as a main component, comprising meltinig a mixture of (A) 100 parts by weight of a polyolefin resin, (B) 0 to 50 parts by weight of a polyester-polyether type thermoplastic elastomer, and (C) a thermoplastic polyester resin having an instrinsic viscosity of not more than 0.5, the amount of the component (C) being from 25 to 90 part by weight per 100 parts of the total amount of the component (A) and the component (B), by heating the mixture at a temperature of not less than the melting temperature of the component (C); kneading the mixture at a shear rate of not less than 200/sec.
