摘要:
A method for joining two ceramic parts, or a ceramic part and a metal part, and the joint formed thereby. The method provides two or more parts, a braze consisting of a mixture of copper oxide and silver, a diffusion barrier, and then heats the braze for a time and at a temperature sufficient to form the braze into a bond holding the two or more parts together. The diffusion barrier is an oxidizable metal that forms either a homogeneous component of the braze, a heterogeneous component of the braze, a separate layer bordering the braze, or combinations thereof. The oxidizable metal is selected from the group Al, Mg, Cr, Si, Ni, Co, Mn, Ti, Zr, Hf, Pt, Pd, Au, lanthanides, and combinations thereof.

Provided is a door basket for a refrigerator. The door basket includes a case, a cover, and a contact member. The case is mounted on a rear side of a refrigerator door and forms a space for receiving food. The cover is axially coupled between both sides of the case and selectively shielding the case through up/down rotation. The contact member is provided on an inner side of the case contacting one end of the cover when the cover is completely opened, and formed of an electrical material to relieve a contact impact with the cover.

A multi-layered high-density recording medium and an optical power adjusting method therefor. A multi-layered high-density recording medium includes multiple recording layers each of which contains optical power related information for all layers. An optical power adjusting method reading first optical power related information for all layers from a multi-layered optical disk placed in a disk player, storing the read information in another storage device, and making a current optical power apparatus to a moved layer without necessarily having to access the multi-layered optical disk by referring to the stored optical power related information when moving to another layer during record or reproduction.

Disclosed herein are a high-density recording medium and a method and apparatus for controlling data playback thereof. Playback control information, such as channel bit length information, is recorded in a burst cutting area (BCA) of a high-density optical disc in a wobble type. When the high-density optical disc is reproduced, the playback control information is detected in a push-pull signal detection mode and the optimum data playback operation corresponding to the recording capacity of the optical disc is performed on the basis of the detected playback control information. Alternatively, bit error rates (BERs) are calculated while a plurality of predetermined bit detection modes are sequentially performed, one of the bit detection modes corresponding to the smallest one of the calculated BERs is selected and the data playback operation is performed in the selected bit detection mode. Therefore, it is possible to perform a data playback operation optimal to the recording capacity of a BD-ROM (Blu-ray Disc-ROM) even through disc information (DI) is recorded in a PIC (Permanent Information & Control data) zone of the BD-ROM in a recording format necessitating a decoding process and the recording capacity is any of different values such as 23 Gbytes, 25 Gbytes, 27 Gbytes, etc.
摘要:
Lithium ion batteries having an anode comprising at least one graphene layer in electrical communication with titania to form a nanocomposite material, a cathode comprising a lithium olivine structure, and an electrolyte. The graphene layer has a carbon to oxygen ratio of between 15 to 1 and 500 to 1 and a surface area of between 400 and 2630 m2/g. The nanocomposite material has a specific capacity at least twice that of a titania material without graphene material at a charge/discharge rate greater than about 10 C. The olivine structure of the cathode of the lithium ion battery of the present invention is LiMPO4 where M is selected from the group consisting of Fe, Mn, Co, Ni and combinations thereof.
摘要:
The present invention provides a method of recording control information in a recordable optical disc including at least one recording layer. In recording control information within a management area of an optical disc including at least one or more recording layers, the present invention includes providing the control information to each of the at least one or more recording layers per recording velocity, recording an information identifying a type of the corresponding control information within the control information, and recording a write strategy (WS) interworking with the type of the control information. In recording a write strategy (WS) within disc information, CLV and CAV are separately recorded, whereby it is able to efficiently cope with the record/playback of the optical disc.

An apparatus, and related method, for recording data that includes a controller to generate control information required to record a main data. The control information including at least one information unit for a specific writing speed and recording layer. The information unit includes write strategy parameters for first write strategy type to be used for the writing speed and recording layer, the first write strategy type being one of an n−1 write strategy type and an n/2 write strategy type, where n is a length of mark and each type represents a number of write pulse to form a corresponding mark. A writing/reading unit records the control information at a specific area of a recording medium, wherein the controller controls the writing/reading unit to record the control information and to record the main data on the recording layer using write strategy parameters for the first write strategy type included in the information unit, at the specific writing speed.
