20090116361 | Recording Method, Recording and Reproducing Method, Reproducing Method, Recording Device, Recording and Reproducing Device, and Reproducing Device for Optical Information Recording and Reproducing Medium, and the Optical Information Recording and Reproducing Medium - Optical information recording and reproducing medium | 05-07-2009 |
20090252009 | POSITIONING CONTROL UNIT AND OPTICAL DISK DRIVE - A position-error-signal calculation circuit ( | 10-08-2009 |
20100288661 | STACKING TYPE TRAY AND TRAY DEVELOPING MECHANISM AND STACKING TYPE TRAY DEVELOPING SYSTEM - To develop optical discs stored while being stacked and to load them to a plurality of recording/reproducing devices simultaneously. Trays for mounting optical discs are stacked to configure an optical disc transportation body, and the portions being exposed without overlapping when the stacked trays are viewed from the stacking direction are utilized as tray operation portions for handling. Supporting portions abutting against the tray operation portions inherent to respective trays in one to one correspondence are fixed with an interval in the vertical direction to the frames configuring a tray distributing/holding portion. The tray operation portion of each tray is held by the supporting portion at each position by moving the optical disc transportation body downward along the frames, and intervals corresponding to the arrangement pitch of recording/reproducing devices are formed between respective trays. | 11-18-2010 |

20140138724 | SUBSTRATE FOR MOUNTING OPTICAL SEMICONDUCTOR ELEMENT, METHOD FOR MANUFACTURING THE SUBSTRATE, AND OPTICAL SEMICONDUCTOR DEVICE - To manufacture a low-temperature co-fired ceramic/high-temperature co-fired ceramic laminated substrate by laminating a porous layer on a dense layer. The porous layer includes a first glass layer, a porous ceramic layer, and a second glass layer laminated on the dense layer in the stated order. The porous ceramic layer contains a glass component and ceramic filler, and has a porosity of 10% or more and 40% or less. A concentration of the glass component at least one of surfaces of the porous ceramic layer in a thickness direction thereof is higher than an average concentration of the glass component in the porous ceramic layer. The dense layer contains a ceramic component, and has a higher transverse rupture strength than the porous ceramic layer. | 05-22-2014 |
