  • Patent number: 7317658
    Abstract: A semiconductor integrated circuit has a memory which can enter active state or standby state, and the memory has voltage generation circuits for bit lines and source lines with which memory cells are connected. The voltage generation circuits make the potential of the bit lines and the potential of the source lines equal to each other in response to an instruction to transition from active state to standby state. The voltage generation circuits produce a potential difference between the bit lines and the source lines in response to an instruction to transition from standby state to active state. In standby state, the potential of the bit lines and that of the source lines are equal to each other. Therefore, sub-threshold leakage does not occur between the source and drain of each memory cell. In active state, the source line potential is not varied.

  • Publication number: 20040151033

  • Patent number: 6287021
    Abstract: Apparatus such as a flexible printed circuit board (FPC) for coupling two electronic components that are configured to move relative to each other such as within a multi-part slide-open type camera, multi-part micro-scope, a scanner device, etc., that includes a first end configured to be coupled to a first electronic component, a flexible connecting member emanating from the first end, and a second end at which the connecting member terminates and which is used to connect the flexible connecting member to a second electronic component. The connecting member includes a component surface used to communicate electrical signals between the fist electronic component and the second electronic component. The flexible connecting member has a shape that permits it to extend and retract in directions substantially perpendicular to the component surface. The shape also permits the flexible connecting member to be maintained in a single plane when in a fully retracted state.

  • Patent number: 5796430
    Abstract: When defective pixels of a solid state image pickup device of a video camera are corrected by signal processes, a white spot noise is detected by closing an iris and by comparing the signal level and a level of only a dark current. Further, in this case, a gain of an AGC circuit for controlling a gain of a video signal is raised and a precise detection is executed. By executing such a detecting operation at the time of turn-on or turn-off of a power source, the user is not annoying. In the ordinary photographing, a reference level in detection of a white spot noise is set to an optimum value in accordance with a temperature of the solid state image pickup device or its peripheral temperature or the gain of the AGC circuit so that the white spot noise detection is not influenced by the temperature of the solid state image pickup device or the operating state of the AGC circuit.

  • Patent number: 5734943
    Abstract: To avoid making a device body larger through positioning of a rotation shaft of a cartridge cover, a device having a device body containing a cartridge chamber into which a film cartridge can be inserted and removed in a axial direction, a cartridge cover provided on the device body which opens and closes the cartridge chamber by rotating about a predetermined axis of rotation, and a device-composing component positioned to the side of the cartridge chamber to extend in a first direction orthogonal to the direction of insertion and removal of the cartridge, the axis of rotation of the cartridge cover extends in a second direction inclined to the first direction from a position near device-composing component. The positioning of the axis of rotation of the cartridge cover in the camera body and not along an edge or corner also improves the camera's aesthetic and ergonomic qualities.
