Abstract: Provided is a method for producing a micro flow channel chip that is used for a treatment or analysis of a liquid sample, the method being capable of producing a micro flow channel chip with high shape accuracy and high efficiency. The method includes a step of forming a groove on one surface of a base material; a lamination step of forming an adhesive resin layer on at least one surface of a resin film, and thereby obtaining a first laminate; and an adhesion step of arranging the surface of the base material where a groove has been formed and the adhesive resin layer of the first laminate to face each other, and bonding the base material and the first laminate such that the adhesive resin layer covers the groove, in which the glass transition temperature of the adhesive resin layer is 25° C. or lower.

Abstract: A micro flow channel chip having high shape accuracy is provided. A micro flow channel chip includes a base material 12 having a groove 121 formed on one surface; and a resin film 14 joined to the surface of the base material 12 so as to cover the groove 121 of the base material 12, in which the resin film 14 contains a (meth)acrylic resin (A), and the (meth)acrylic resin (A) contains a structural unit (A1) represented by Formula (1). (In Formula (1), R1 and R2 each independently represent a hydrogen atom, a methyl group, an ethyl group, or a propyl group; and R3 represents an alkyl group having 3 to 6 carbon atoms).

Abstract: An object of the present invention is to provide a flow channel device which hardly generates air bubbles within a flow channel and includes: a base material having a groove; and a coating material which is integrated with the base material so as to cover the groove, in which the difference (?1??2) between a contact angle (?1) of a portion facing the groove in the coating material with respect to pure water and a contact angle (?2) of the groove portion of the base material with respect to the pure water is ?30° to 30°.

Abstract: An objective is to prevent a downloaded application from accessing data in an external memory unrelated to the application, and to achieve safer management of access to the external memory. An external memory function module 15 is a function module that controls access of an application downloaded in a cell phone 1, to an external memory 2. This external memory function module 15 has a bind ID acquirer 156 for acquiring a bind ID to specify the application downloaded, a discrimination ID acquirer 157 for acquiring a directory discrimination ID to specify an application permitted to access a directory, and an access controller 158 for checking the bind ID against the directory discrimination ID and for, when they coincide with each other, performing such control as to permit access of the application to the directory.

Abstract: An objective is to prevent an unauthorized application from falsifying and assuming specific information generated for access to an external memory, without permission, and to achieve safer management of access to the external memory. An external memory function module 15 is a function module to control access of applications 101A and 101B downloaded in a cell phone 1, to an external memory 2. This external memory function module 15 has an identifier acquirer 151 for acquiring an identifier from each of the applications 101A and 101B, a generator 153 for generating specific information to specify the application, based on identification information designated by the identifier acquired, a reserving section 154 for reserving a predetermined area of the external memory 2 as a directory for the application, and a writing section 155 for writing the specific information generated, in an attribute file of the external memory 2.

Abstract: A data transmission control system includes a server configured to store an application program having a data area in which transmission control information containing a threshold value used to detect abnormal data transmission is stored and to allow the application program to be downloaded in response to a request, and a mobile device that downloads the application program from the server. The mobile device comprises a management table recording the transmission control information extracted from the downloaded application program; a counter configured to count a number of messages or traffic volume per unit time; a detector configured to compare the counted value with the threshold value contained in the transmission control information to detect abnormal data transmission; and a transmission regulating unit configured to restrict data transmission upon detection of the abnormal data transmission.

Abstract: A data communication restriction method for flat rate users is disclosed. The data communication restriction method comprises the steps of: monitoring data communication status of a flat rate user, and determining whether the number of request or communication quantity during a predetermined period exceeded a predetermined threshold (S9); setting the flat rate user as a communication restricted object when it is determined that the threshold was exceeded (S10); and transmitting a communication restriction signal including communication restriction period information to a mobile terminal of the restricted flat rate user, when the restricted flat user requested access again (S11); whereby data communication of the mobile terminal of the restricted flat rate user is restricted during the communication restriction period.
