Abstract: Disclosed are a multimedia device controller, a source device, a sink device and a transmission system that can manage multimedia devices capable of simultaneous output of video and audio from multiple Blu-ray discs or the like. A master device (110) references a source/sink device function management table (200) and a band management table (300) and controls the video and audio bands for the source and sink devices during transmission of multiple video and audio signals. When a band that is kept is changed, the master device (110) also confirms the status of a transmission path (100) and the content usage conditions of sink devices (140, 150) and controls the band. For example, when the master device (110) outputs two sets of video and audio in one set, the band is changed to one band in which the two sets of video and audio are synthesized.

Abstract: An equipment control apparatus capable of improving the command communication efficiency, wherein the equipment control apparatus (1) is provided with a receiver (11) for receiving an operation code transmitted from an operation device (3), and a processing unit (14). When the receiver (11) receives the operation code, the processing unit (14) determines whether or not the target source equipment (2) is compatible with the pass through control of the operation code, and upon determining that the source equipment (2) is incompatible, the processing unit (14) stops transmitting the command for transferring the operation code to the source equipment (2).

Abstract: The invention relates to a method of laminating ceramic greenware sheets with electrodes embedded therein (25) which is formed on a support by pressure-adhering a ceramic greenware sheet with an electrode embedded therein onto a second ceramic greenware sheet or other electrodes (23), then peeling off the support alone and transferring the ceramic greenware sheet with the embedded electrodes onto the second ceramic greenware sheet or the other electrodes. This manufacturing method enables it to laminate ceramic greenware sheets each the thickness of which is as thin as 20 micrometers or less, while maintaining their mechanical strength and embedded electrodes in the ceramic greenware sheets, thereby enabling it to prevent a occurrence of surface irregularities due to the thickness of the electrodes even when laminating to a high degree.

Abstract: A method of manufacturing a ceramic electronic part includes the steps of: firing Pd electrodes or alloy electrodes containing Pd as a primary metal along with ceramics in the atmosphere in which Pd cannot be oxidized within the range (I) of oxidizing temperature of Pd in air; and firing the Pd electrodes or alloy electrodes along with the ceramics in air within the range (II) of deoxidizing temperature of PdO in air. The method can manufacture a ceramic electronic part, such as a multilayer ceramic capacitor, including Pd electrodes or alloy electrodes which contain Pd as a primary metal without forming internal defects inside the ceramic electronic part and reducing its properties.

Abstract: A composition consisting of 5 to 95 mol% of bismuth oxide (Bi.sub.2 O.sub.3) and 95 to 5 mol% of copper oxide (Cu.sub.2 O), or a composition consisting of 50 to 95 mol% of copper oxide (Cu.sub.2 O) and 50 to 5 mol% of manganese dioxide (MnO.sub.2), or a composition consisting of 5 to 95 mol% of bismuth oxide (Bi.sub.2 O.sub.3) and 95 to 5 mol% of manganese dioxide (MnO.sub.2), is thermally diffused in the grain boundaries of semiconductor ceramics composed mainly of strontium titanate (SrTiO.sub.3) to form highly insulating layers in the grain boundaries to thereby provide semiconductive ceramics wherein the rate of change of dielectric constant with temperature as well as the dielectric loss (tan .delta.) are smaller than in the conventional barium titanate type semiconductor products. Further, the insulation resistance is higher than in the conventional product.
