  • Patent number: 7317794
    Abstract: The present invention aims at providing a novel enciphering and deciphering apparatus and an enciphering and deciphering method related thereto, which are respectively capable of contracting the time required for enciphering and deciphering processes and decreasing the number of logic gates provided in the apparatus.

  • Patent number: 7218142
    Abstract: A switch circuit that is simple in constitution and capable of reliably controlling a switch cell is provided. Since the, gate terminal G1 of a transistor M1 in a switch cell SC is connected only to the terminal 37 of a transistor M2, when the transistor M2 is set to off, the moving path of the charge accumulated at the gate G1 of the transistor M1 is shut off. Consequently, even if the transistor M2 is set to an on state and immediately set back to an off state, the transistor M1 remains for some period of time in an on or off state corresponding to the switching data given through a bit line BL. It is possible to cause the transistor M1 to remain in an on or off state for a specified period of time without disposing a specific circuit for temporary storing the switching data.

  • Patent number: 7066637
    Abstract: A space that closely approximates the state of an actual flame is reproduced without depending on temporal periods. Namely, by reproducing a spatiotemporal pattern of a flame, the light source can be caused to emit warm light, whereby a compact and inexpensive imitation flame generating apparatus is provided. The imitation flame generating apparatus 1 comprises a light source 10 and a control device 40 for controlling the output of electric current to the light source 10. The control device 40 comprises computation means 41 for computing a spatiotemporal pattern of the flame using a coupled map lattice, and output means 42 for outputting the electric current in accordance with the thus computed spatiotemporal pattern of the flame.

  • Patent number: 7039847
    Abstract: A coding-decoding device and a coding-decoding method that take less time for coding and decoding are provided while using less number of logic gates. A memory device 15 substantially stores b pieces of conversion logic equations produced with a conversion logic equation producing device 13. An operation device 17 has a programmable hardware logic circuit to constitute logics sequentially according to plural execution unit logic equations obtained by dividing b pieces of conversion logic equations stored in the memory device 15 into execution units for respective execution unit logic equations using the hardware logic circuit. Besides, the operation device 17 sequentially divides and calculates the second sentences from the first sentences according to the constituted logics. An output device 19 collects and outputs the second sentences calculated with the operation device 17.

  • Patent number: 7038930
    Abstract: To provide a memory device with a function to perform an operation and a method of performing an operation and storage which can save space and cost and which can start, immediately after the power source is recovered, the processing which was being performed at the time of power failure. A memory cell MC can store two independent data sets; DRAM data (volatile data) and FeRAM data (non-volatile data). Thus, the number of memory cells can be reduced to a half. Also, the DRAM data to be used in the next operation of the two data sets which have been read out for the previous operation are temporarily held in a hold circuit 21 of an operation unit OU and then written back into the memory cell MC in a non-volatile manner as new FeRAM data for preparation of the next operation. Thus, even when the power source is shut down by an unexpected trouble, the data necessary for the next operation are not lost.

  • Patent number: 6806723
    Abstract: Contact electrodes having a predetermined shape are formed by irradiating a laser beam onto the contact electrodes that are formed of a conductive material. The laser beam can be irradiated, after joining an end of each contact electrode opposite to a contact end to a contact board, so as to deform the contact electrode so that the contact end is located at a predetermined position. The laser beam may be irradiated while heating or cooling a portion of the contact electrode opposite to a portion onto which the laser beam is irradiated.
