  • Patent number: 8477855
    Abstract: Disclosed is a semiconductor integrated circuit device including a transmitting circuit and a receiving coil inductively coupled to a transmitting coil. The transmitting circuit transmits data by supplying a current through the transmitting coil not at the time of transition of data but at every rising edge or falling edge of a clock used in transmission of data. At every rising edge or falling edge of the clock, a receiving circuit captures a voltage induced in the receiving coil due to the current flowing through the transmitting coil, reproduces the transmitted data and outputs the reproduced data.

  • Patent number: 8467256
    Abstract: An electronic circuit for which a coil 22 is disposed overlapping with a memory array region to carry out communications by inductive coupling between stacked and mounted chips by the coil 22. Because intersections 1 and 2 between the coil 22 and a bit line 15 are located at a pair of positions that are equal to each other in wiring length from both terminals a and g of the coil 22, interference from the bit line 15 to the coil 22 results in the same phase and same amplitude at both ends of the coil 22, and can thus be eliminated by a differential amplifier. Thereby, a coil antenna can be disposed so that, even when a coil antenna to carry out communications by inductive coupling is disposed overlapping with a memory array region, little interference occurs from a memory array wiring to communications by the coil antenna.

  • Patent number: 8423850
    Abstract: A pulse transmission technique is used for wireless communication between a microcomputer (13) having a debugging support circuit (17) and a debugger (13). The pulse transmission technique is based on magnetic field coupling between a first coil (14) provided for the microcomputer and a second coil (8) coupled with the debugger. During an initialization operation, the microcomputer performs a process of configuring a communication condition of the wireless communication to perform the wireless communication. The microcomputer awaits control from the debugger when the microcomputer establishes communication with the debugger. The debugger awaits establishment of the communication and proceeds to control of the microcomputer in accordance with the wireless communication. It is possible to provide contactless interface for system debugging without the need for a large antenna or a large-scale circuit for modulation and demodulation.

  • Patent number: 8309056
    Abstract: Provided is a biomarker that enables easy and rapid detection of oxidative stress on a living organism and enables prevention of tissue damage or cell necrosis by drug administration, and which is a powerful marker for the study of toxicity and pharmacokinetics of various agents. Oxidative stress is determined by measuring blood concentration of ophthalmic acid, which is a substance that varies in blood depending on the variation of reduced glutathione (GSH) concentration in a biological sample with the use of an analyzer such as a capillary electrophoresis-mass spectrometer. Further, an anti-oxidative stress agent is screened by administering an anti-oxidative stress candidate agent to a non-human animal under oxidative stress conditions, measuring blood concentration of ophthalmic acid, and evaluating the degree of decrease in the ophthalmic acid concentration.

  • Patent number: 8276822
    Abstract: An electronic circuit, for which a coil 22 is disposed being overlapped with a region of a memory array 11, carries out communications by inductive coupling between stacked and mounted chips by means of the coil 22. Because each side of the coil 22 is disposed so as not to be parallel to a word line and a bit line 15, crosstalk between ‘the coil 22’ and ‘the word line 14 and bit line 15’ can minimized. This allows efficiently arranging a coil to carry out communications by inductive coupling between chips to be stacked and mounted.
