  • Patent number: 7572648
    Abstract: A cubic element of photonic crystal is integrally formed on the surface of a photo-detection element, and a portion of the photonic crystal cubic element is irradiated with ultraviolet rays thereby to change the refractive index of the portion of the cubic element that has been irradiated with ultraviolet rays. Alternatively, by causing globular particles having different refractive indices to eject on the surface of the photo-detection element from an ink-jet apparatus having a nozzle provided with a temperature control part by controlling temperature of the nozzle to form a laminate of globular particle layers having different refractive indices, a photonic crystal lens is integrally formed on the surface of the photo-detection element.

  • Patent number: 7541951
    Abstract: A tracking loop type digital angle converter that operates so that a deviation between input and output angles always becomes zero by feeding back the output angle to the input angle, wherein in order to eliminate a case where a control deviation decreases an angle error between the input and output angles is in the vicinity of 180°, i.e., where response becomes low, there are provided a detected signal sign judging section (41) that judges signs of rotation detection signals to determine a quadrant where the input angle exists, and an output angle correcting section (42) for comparing an angle region of the output angle and the quadrant of the input angle to detect a state where the angle error is excessive, judging that the control response is low and carrying out a process for compensating the output angle.

  • Patent number: 7536299
    Abstract: Transmitters and receivers in multiple description coding systems use correlating and decorrelating transforms to generate and process multiple descriptions of elements of an input signal. The multiple descriptions include groups of correlating transform coefficients that permit recovery of an inexact facsimile of the signal if some of the correlating transform coefficients are lost or corrupted during transmission. Noiseless implementations of the correlating and decorrelating transforms are described that allow the signal elements to be quantized with different quantizing resolutions. Implementations using the Fast Hadamard Transform are described that reduce the resources needed to perform the transforms.

  • Patent number: 7516064
    Abstract: Analysis and synthesis filter banks such as those used in audio and video coding systems are each implemented by a hybrid transform that comprises a primary transform in cascade with one or more secondary transforms. The primary transforms for the filter banks implement an analysis/synthesis system in which time-domain aliasing artifacts are cancelled. The secondary transforms, which are in cascade with the primary transforms, are applied to blocks of transform coefficients. The length of the blocks is varied to adapt the time resolution of the analysis and synthesis filter banks.

  • Patent number: 7515783
    Abstract: A micro-optic device including a complicate structure and a movable mirror is made to be manufactured in a reduced length of time. A silicon substrate and a single crystal silicon device layer with an intermediate layer of silicon dioxide interposed therebetween defines a substrate on which a layer of mask material is formed and is patterned to form a mask having the same pattern as the configuration of the intended optical device as viewed in plan view. A surface which is to be constructed as a mirror surface is chosen to be in a plane of the silicon crystal. Using the mask, the device layer is vertically etched by a reactive ion dry etching until the intermediate layer is exposed. Subsequently, using KOH solution, a wet etching which is anisotropic to the crystallographic orientation is performed with an etching rate which is on the order of 0.1 ?m/min for a time interval on the order of ten minutes is performed to convert the sidewall surface of the mirror into a smooth crystallographic surface.

  • Patent number: 7499609
    Abstract: A blocking portion is provided at an end of the mirror to prevent a light beam emitted from an input port from being transmitted to or reflected by first and second output ports. The mirror is inserted to a position where the end of the blocking portion of the mirror reaches a boundary P2? on the insertion side of an area to be blocked to obtain a permissible crosstalk value of the light beam. The mirror is removed to a position where the rear end of the blocking portion of the mirror reaches a boundary P2 on the removal side of the area to be blocked. The mirror is movably driven between the removal position and the insertion position in the optical path of a first light beam by a drive. Thus it is possible to reduce the length of the driving stroke of the mirror.

  • Patent number: 7484207
    Abstract: It is possible to prevent unauthorized use of software such as a game program in download type software distribution for using a program and data by storing them in a user computer in advance. A user downloads a game program of new version (including an accompanying data group) and an execution program from a distribution computer. The execution control program performs authentication by online with an authentication computer and acquires start information required for starting the game program. The execution control program decodes the game program according to the start information and starts it. When the user terminates the game by terminating the game program, the execution control program deletes all or part of the game program so as to incapacitate it.
