摘要:
A dielectric ceramic composition comprising a main component including BaTiO3, a fourth subcomponent including an oxide of R1 (note that R1 is at least one selected from Y, Ho, Er, Tm, Yb and Lu) and a fifth subcomponent including an oxide of R2 (note that R2 is at least one selected from Dy, Tb, Gd and Eu); wherein a total number of moles of R1 and R2 with respect to 100 moles of the main component is 2 to 6 moles when calculated as a conversion of the R1 and a conversion of the R2, and a ratio of the fifth subcomponent to the total number of moles of R1 and R2 with respect to 100 moles of the main component is in a relationship of 0.5≦R2/(R1+R2)≦0.75 when calculated as a conversion of the R1 and a conversion of the R2. According to the present invention, a high temperature load lifetime and capacity-temperature characteristics can be well balanced even when the dielectric layer of the electronic device is made thin, so that a sufficiently reliable dielectric ceramic composition can be provided.

An information processing system comprising: an acceptance unit configured to receive an issuance request of an electronic certificate that is available in an electronic apparatus used by one or more users; an issuance unit configured to issue the electronic certificate based on the issuance request received by the acceptance unit; a management unit configured to store information indicating the electronic certificate issued by the issuance unit associated with information indicating one or more services that can be used with the electronic certificate, the one or more services being provided respectively by one or more servers; and a reporting unit configured to transmit authentication information for determining validity of the electronic certificate to at least one server among the one or more servers based on the information stored in the management unit.
摘要:
A registration part receives a product key of a program for performing a communication using a private key and a public key, and discrimination information of a computer using the program. The registration part registers in a management part, when an authentication of a license corresponding to the product key is completed in success, correspondence information between the product key and the discrimination information and other discrimination information regarding the correspondence information. A discrimination information sending part returns the other discrimination information to an electronic certificate issue apparatus. A checking part receives the other discrimination information and check whether the other discrimination information is registered in the management part. A certificate producing part produces, when the other discrimination information is registered in the management part, an individual certificate package containing the private key and the public key for each piece of the other discrimination information.
摘要:
An information processing apparatus and a counterpart apparatus supporting data communications are devised. The information processing apparatus is connected to the counterpart apparatus via a communication network. The information processing apparatus and the counterpart apparatus supporting data communications use mutual authentication using a certificate file. The information processing apparatus includes a certificate management unit, a verification information obtaining unit, and a security key generation unit. The certificate management unit encrypts and decrypts the certificate file using a security key. The verification information obtaining unit obtains verification information of the information processing apparatus. The verification information enables identification of the information processing apparatus as a unique physical entity. The security key generation unit generates the security key by conducting a non-reversible transformation of the verification information obtained by the verification information obtaining unit. The verification information is used as source data.
摘要:
In a data processor and a shading apparatus used in the data processor, the data processor selects an address based on the information of a memory or a translation look-aside buffer. Therefore, even when the same data are accessed, a different address at high speed is adopted according to the hardware, object to be processed, processing, etc. A plurality of geometric vectors are given as the parameters for the vertexes of a picture, the vectors are interpolated in the picture, and the luminance of each small area in the figure is calculated using the vectors generated by the interpolation. Therefore, a spotlight or highlight can be expressed with high accuracy and at high speed even when the amount of the hardware and the extent of the picture are small.
