A secure processor system capable of improving the security of processor processing by the addition of minimum modules without the need for a manufacturer and a user to know encryption information of each other has been disclosed. The secure processor system includes a secure processor having a CPU core that executes a instruction code, an encryption key hold part that holds a processor key, and an encryption processing part that encrypts or decrypts data input/output to/from the core with a processor key and a memory, and the encryption key hold part includes a hardware register that holds a hardwired encryption key, a write only register that stores an encryption key for instruction to be input and holds the stored encryption key for instruction so that it cannot be read, and the encryption key hold part outputs a hardware encryption key as a processor key at the time of activation and outputs a command encryption key as a processor key after a encryption key for instruction is written.

摘要:
To provide a heat resistant filter of which the reduction of tensile strength and folding endurance is small even when used as a filter material for a filter used at high temperatures, failure of the filter material is difficult even when used at high temperatures, and which is capable of achieving a long life. The heat resistant filter contains: a heat resistant organic fiber base material, and a resin composition which contains an alkaline substance and which adheres to the heat resistant organic fiber base material.

A circularly polarizing plate includes a λ/4 phase difference plate and a linearly polarizing plate overlaid on a main surface of the λ/4 phase difference plate and having an absorption axis forming an angle of about 45° with respect to a lagging axis of the λ/4 phase difference plate. The λ/4 phase difference plate has reverse wavelength dispersion characteristics and an Nz coefficient of 1.6 or more. Employment of this structure can provide the circularly polarizing plate having good view angle characteristics and a vertical alignment type of liquid crystal display panel having the same.
摘要:
A graphics drawing device capable of reducing the amount of information transferred. In the graphics drawing device for drawing graphics, a first storage circuit stores coordinate information and attribute information about a main graphic which is an original graphic. A second storage circuit stores coordinate information and attribute information about one or two or more derivative graphics derived from the main graphic. A drawing circuit draws the main and derivative graphics in accordance with the information stored in the first and second storage circuits, and a control circuit controls the drawing process performed by the drawing circuit.

Pastes for circuit connections and anisotropic conductive pastes that are excellent in storage stability and dispenser application properties, can be free of voids, bubbles and bleeding on thermocompression bonding and can give cured products having high bonding and connection reliability at high temperatures and high humidity, and the ability to be repaired. The paste for circuit connection contains an epoxy resin, an acid anhydride curing agent or a phenolic curing agent, and high-softening point fine particles. The anisotropic conductive paste additionally contains conductive particles. The method of using the paste for circuit connection or the anisotropic conductive paste involves connecting an electric circuit wiring formed on a substrate with an electric circuit wiring formed on another substrate with the paste for circuit connection or the anisotropic conductive paste.
