  • Publication number: 20240142952
    Abstract: An access authority is set for each data referred to by a program. A control system includes a control unit that controls a control target, a storage unit that stores a program executed by the control unit and each access authority for each of data referred to by the program, and an input unit that receives an access request for any one of the data. Each access authority includes information about an operation that can be executed by a user having each authority. The control unit refers to each access authority based on acquisition of the access request for any one of the data from the input unit, and determines whether the user who transmits the access request has the access authority for the data for which the access is requested based on each access authority.

  • Patent number: 7689834
    Abstract: The present invention provides a personal authentication apparatus that includes a permissibility information file for registering information indicating whether setting an ID common to more than one person is permitted or not. In the apparatus, only if setting of an ID common to more than one person is prohibited, an information registering section refers to the permissibility information file to check whether or not a first ID currently obtained for registration is identical to any of second IDs stored in an information storing section. Then, only if the first ID differs from any of the second IDs, the information registering section registers the first ID and biometric information currently obtained in an information storing section.

  • Patent number: 7320916
    Abstract: When Ti as a barrier metal layer is brought into contact with a diffusion region of boron provided on a surface of a silicon substrate, there is a problem that boron is absorbed by titanium silicide, and contact resistance is increased. Although there is a method of additionally implanting boron whose amount is equal to the amount of boron absorbed by titanium silicide, there has been a problem that when boron is additionally implanted into, for example, a source region in a p-channel type, the additionally added boron is diffused deeply at the diffusion step, and characteristics are deteriorated. According to the invention, after formation of an element region, boron is additionally implanted into the whole surface at a dosage of about 10% of an element region, and is activated in the vicinity of a surface of a silicon substrate by an alloying process of a barrier metal layer.
