Abstract: A multi-chip device includes a first material within a substrate. The first material has a first coefficient of thermal expansion different than a second coefficient of thermal expansion of the substrate. A first chip overlies a first portion of the first material and a first portion of the substrate. A second chip overlies a second portion of the first material and a second portion of the substrate. The first material is between the first portion of the substrate and the second portion of the substrate.

Abstract: The present invention discloses a tactile remote control system, which uses a processor to integrate the operation selection items of controlled devices and arrange the selection items into a graphic user interface, and which uses a microswitch to output instructions. The processor arranges the graphic user interfaces of a controlled device hierarchically. Therefore, the graphic user interfaces have organizationality, logicality and continuity. The user watches the display and operates the microswitches to remotely control the controlled devices. The present invention integrates the control functions to assist the user to control the daily-life electronic devices and household appliances. The present invention enables any one, who has been briefly instructed, to remotely control the linked devices by his will.

Abstract: An optical recording medium is provided with inorganic bi-layer films that were prepared by magnetic sputtering. A first recording layer containing an element selected from Si or Ge, and a second recording layer contacts with the first recording layer and containing a primary component selected from Ta, Ni or Mo. This optical media can record information by way of microscopic structure changing of bi-layer recording films after laser irradiation.

Abstract: A method for improving read stability of optical recording medium is disclosed. In the method, the thickness of a recording layer of an optical recording medium is adjusted to control the disc absorptivity, and the recording layer thickness is matched with a power difference between a laser write power (Pw) and a laser erase power (Pe), so as to control the optimal laser power for irradiating and accordingly changing the optical properties of the recording layer. It is found that by using properly increased recording layer thickness corresponding to a given disc absorptivity, and properly matching the recording layer thickness with a properly increased power difference, the read stability and recording characteristics of the optical recording media can be improved without significantly changing the layer structure and writing strategy of the optical recording medium.
