  • Patent number: 8980530
    Abstract: An optical information recording medium 10 comprises a plurality of recording layers 14, and intermediate layers 15 each provided between the recording layers 14. Each of the recording layers 14 includes polymer binder and dye dispersed in the polymer binder, and the dye is subject to multi-photon absorption of a recording beam RB having a predetermined wavelength and to linear absorption not smaller than 1.5% per recording layer at the predetermined wavelength of the recording beam. When the dye is irradiated with the recording beam and generates heat by linear absorption and multi-photon absorption of the recoding beam RB, the polymer binder undergoes a change of shape by the generated heat, whereby an interface between the recording layer 14 and the intermediate layer undergoes a change of shape to record information.

  • Publication number: 20140153375
    Abstract: An optical information recording medium comprises recording layers which include a polymer binder and a dye dispersed in the polymer binder or include a polymer to which a dye is bonded, and each recording layer has a refractive index unchangeable under irradiation with a recording beam, with first and second interfaces being defined between the recording layer and two intermediate layers adjacent thereto. Irradiation of a region of the recording layer adjacent to the first interface or a region of the recording layer adjacent to the second interface with the recording beam causes the dye to absorb the recording beam and generate heat which in turn deforms the polymer in the recording layer, forming a protrusive shape protruding into an intermediate layer at the first or second interface whereby information is recordable in separate information layers at both of the first and the second interfaces.

  • Patent number: 8730703
    Abstract: Efficient reduction in power consumption is achieved by combinational implementation of a power cutoff circuit technique using power supply switch control and a DVFS technique for low power consumption. A power supply switch section fed with power supply voltage, a circuit block in which a power cutoff is performed by the power supply switch section, and a level shifter are formed in a DEEP-NWELL region formed over a semiconductor substrate. Another power supply switch section fed with another power supply voltage, a circuit block in which a power cutoff is performed by the power supply switch section, and a level shifter are formed in another DEEP-NWELL region formed over the semiconductor substrate. In this arrangement, there arises no possibility of short-circuiting between different power supplies via each DEEP-NWELL region formed over the semiconductor substrate.

  • Patent number: 8670296
    Abstract: An optical information recording medium includes: a recording layer 12 comprising a multi-photon absorption compound and a one-photon absorption compound; and a supporting member (base layer 11) configured to support the recording layer 12. In this optical information recording medium, absorption of multiple photons by the multi-photon absorption compound and absorption of one photon by the one-photon absorption compound cause a void to be generated in the recording layer, whereby information is recordable by modulation based on a presence or absence of a void.

  • Patent number: 8421527
    Abstract: The present invention is directed to perform fine low-voltage control without largely increasing the circuit layout area in a low-power consumption structure. In the case of shifting a region to a low-speed mode, a system controller outputs a request signal and an enable signal to a power switch controller and a low-power drive circuit, respectively, to turn off a power switch and to perform a control so that the voltage level of a virtual reference potential becomes about 0.2 V to about 0.3V. The region operates on voltages between a power supply voltage and a virtual reference potential, so that it is controlled in the low-speed mode.

  • Patent number: 8400806
    Abstract: A technology that makes it possible to reduce fluctuation in operating voltage for operating the circuits formed in the core region of a semiconductor device is provided. This semiconductor device is so arranged that the core region is divided into multiple functional blocks and power can be supplied and this power supply can be interrupted with respect to each of the divided functional blocks. The core region formed in the semiconductor chip is divided into multiple functional blocks. A power switch row in which multiple power switches are arranged is disposed in the boundaries between the divided functional blocks. These power switches have a function of controlling the supply of reference potential to each of functional blocks and the interruption of this supply. A feature of the invention is that reference pads are disposed directly above the power switch rows. This shortens the wires coupling together the reference pads and the power switches.
