Title: Optical disk device
Inventor: TAKEDA NAOTO
IPC: G11B7/0045
Filed: 2001-08-30
Abstract: PROBLEM TO BE SOLVED: To make a high-quality data recording in a recording-capable optical disk device. SOLUTION: A controlling part 24 carries out OPC by using the PCA area of an optical disk 10 and computes tentative optimum recording power. The length of a laser beam wavelength is evaluated based on the size of the tentative recording power. When the laser beam wavelength is shifted on the side of long wavelength, the controlling part 24 changes it to a recording strategy for long wavelength, and when it is shifted on the side of short wavelength, the controlling 24 changes it to the recording strategy for short wavelength. After the recording strategy is changed, the optimum recording power is computed with the residual part of the PCA area, and the data are recorded with the recording strategy changed and the optimum recording power.

Title: Image processor and image processing program
Inventor: TANAKA SHIGENORI
IPC: G06T15/04
Filed: 2001-09-18
Abstract: PROBLEM TO BE SOLVED: To produce a three-dimensional computer graphics of a subject from a pair of stereo images of the subject. SOLUTION: A pair of stereo image is photographed for an object of expression of the three-dimensional computer graphics as a subject. The corresponding points of the object are extracted from the photographed pair of stereo images, and two-dimensional coordinate values on the left image and the right image of these points are calculated. From the combination of these points, a pair of stereo images are measured in a photograph. At this moment, calculation accuracy is raised by using a hereditary algorithm and renewing the combination of the points. When a three-dimensional coordinates data of the object is obtained from the calculation, by using it, a polygon is produced and solid model of the object is described by VRML.

Title: Power circuit, electronic apparatus equipped therewith, and method of controlling the same
Inventor: SASAKI HIROSHI
IPC: H01M10/44
Filed: 2001-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a power circuit which is excellent in use efficiency of a chemical battery and besides is resistant to intermittent change of a load current. SOLUTION: In odd-numbered load burst periods, load L is driven by the power accumulated in a capacitor 16. In even-numbered load burst periods, the load L is driven by the power accumulated in a capacitor 17. Consequently, even if the duty ratio in the load burst period in one cycle when the load burst periods occur intermittently is 50% or over, the supply of energy in the load burst period is performed from a capacitor 16 or 17, and in the load burst period, a chemical battery 11 does not discharge. Therefore, the quantity of drop of a voltage value A by the internal impedance of the chemical battery 11 becomes small, so the operation life of the chemical battery 11 is extended by using this power circuit for an electric apparatus which ceases to operate by the temporary voltage drop of a power source.

Title: Sound processing system in atm network and its sound processing method
Inventor: TAKIZAWA SEIJI
IPC: H04L47/43
Filed: 2001-09-20
Abstract: PROBLEM TO BE SOLVED: To suppress a processing delay caused by two times of CRC check operation by a sound processing system. SOLUTION: The system is composed of a CPS (common part sublayer) processing unit 1 and an IuPU processing unit 2. Sound data processed by the CPS processing unit 1 and the IuPU processing unit 2 are subjected to a protocol conversion based on an IuUP protocol and a CPS protocol. The IuUP protocol is defined to be of higher order than the CPS protocol by the specification standards. The CPS processing unit 1 does not execute the CRC check operation while the IuPU processing unit 2 executes the CRC check operation when processing the sound data after received them. Since only UUI (user-to user indication)=26 is used a CPS header and an IuUP header are attached together without fail in the CPS header. Although a CRC 116 check operation is not performed in the CPS header, the normality of ATM cells can be confirmed if the CRC check operation in the IuUP header is performed.  The procedure omission in which the CRC check of the CPS header is not executed can relax the delay of the signal processing.

Title: Disk device and method for controlling carrying of optical pickup

Filed: 2001-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a disk device capable of suppressing pull-out of a stepping motor from taking place, and to provide a method for controlling the carrying of an optical pickup. SOLUTION: The disk device is mounted with a function of controlling the maximum number of revolutions of the stepping motor depending on the number of times of occurrences of pull-out. When the carrying of the optical pickup by seeking is finished, a control section of the disk device obtains a difference (hereinafter called a positional deviation) between a current address supplied from a decoder and a target address received from a host computer at the star of the seeking and compares the obtained positional deviation with a permissible positional deviation Δ set in advance to the disk device (step S5).  When the control section decides that e.g. the obtained positional deviation exceeds the permissible positional deviation Δ and the stepping motor reaches pull-out (step S5; NO), the control section sets the maximum number of revolutions of the stepping motor to be lower than that set at the previous seeking (step S6 to step S7 to step S9).
