摘要:
A server apparatus performs data I/O processing on a P-VOL in response to a request from a client apparatus and includes a file system which receives data write and read requests in units of files from the client apparatus. The server apparatus stores, into a D-VOL, differential data generated by updating the P-VOL, and manages a snapshot management table wherein a block address of the D-VOL storing the acquired differential data is registered. When a remaining capacity of a storage area of the D-VOL becomes equal to or less than a predetermined threshold value, the server apparatus enables a block of the D-VOL which had stored therein the differential data on a certain predetermined file, to be used as a storage area for newly acquired differential data.

Upon start of processing, a digital broadcast receiver can acquire a CDN configuration information file (XML) after newly connected to a CDN by a user's operation. Next, the digital broadcast receiver acquires a PF configuration information file written in the CDN configuration information. The digital broadcast receiver judges whether there is an IP broadcast or not. If there is an IP broadcast, the digital broadcast receiver connects to a multicast address described in the PF configuration information file (XML), and acquires information on all channels in the PF from a SI dedicated stream (all station SI including no video or audio) (channel scan). The URL of a SNTP is described in the CDN configuration information file. Time information is acquired through the SNTP at the same time as (or at a timing near the timing of, such as immediately before or immediately after) the channel scan. The above processing enables easy time acquisition which is a problem peculiar to an IPTV with which viewing of an IP broadcast is possible.

There are provided an electronic component in which two substrates are bonded to each other with a large bonding force and a method for manufacturing electronic components in which two substrates can be bonded to each other with a large bonding force and in which the substrates are not likely to be bent and broken. In an embodiment, a plurality of first connection portions 30 is formed on a first substrate 22, and in addition, a plurality of IDT electrodes 26 and a plurality of second connection portions 32 are formed on a second substrate 24. The first connection portions 30 are engaged in concave parts of the second connection portions 32, so that temporary bonding is performed. Between adjacent first connection portions 30, only the first substrate is cut. By heat application, laser irradiation, pressure application, ultrasonic application, or the like, the first connection portions 30 and the second connection portions 32 are finally bonded to each other. The second substrate 24 is cut along the cut portions of the first substrate 22, so that a plurality of electronic components 20 is formed.

A manufacturing method for an electronic component includes a process of forming a lower electrode and a dummy electrode, which are electrically connected to each other, on a substrate, and a process of forming a piezoelectric thin film on the dummy electrode and the lower electrode while a predetermined bias potential is applied to the lower electrode via the dummy electrode. In this method, the piezoelectric thin film is formed on the lower electrode by stabilizing the potential of the lower electrode, thereby decreasing the surface roughness of the piezoelectric thin film. It is thus possible to manufacture an electronic component that exhibits excellent piezoelectric characteristics, in which the electromechanical coupling coefficient and the quality factor of a resonator are increased.

A piezoelectric resonator suitable for use in a high frequency band is provided, in which variation in the piezoelectric material is reduced, variation in performance is reduced, and production can be performed without the need for a polarization treatment step. In the piezoelectric resonator, a piezoelectric material made of a wurtzite structure compound crystal is disposed, the crystal epitaxially grown in such a way that a (1,1,−2,0) crystal face becomes parallel to a surface of the R-plane sapphire substrate having a (0,1,−1,2) crystal face parallel to the substrate surface, and a pair of excitation electrodes are disposed on a pair of principal surfaces opposite to each other in the thickness direction of the piezoelectric material in such a way that the pair of excitation electrodes sandwich the C plane which is a (0,0,0,1) crystal face perpendicular to the (1,1,−2,0) crystal face of the tabular piezoelectric material.
