  • Patent number: 8291458
    Abstract: A digital broadcast receiver includes an operation mode manager that switches an operation mode to a first mode in which a function is implemented by the downloaded application or a second mode in which a function is implemented by the pre-installed application, and a key delivery module that delivers the key code received from the remote control to the downloaded application or the pre-installed application. When the receiver is in the first mode, the key delivery module delivers the received key code to the downloaded application if the received key code is a key code for the first mode, and delivers the received key code to the pre-installed application if the received key code is a key code for the second mode. When the receiver is in the second mode, the key delivery module delivers the received key code to the pre-installed application.

  • Patent number: 8105763
    Abstract: A method is provided that enables the formation of multiple level plated products with large plating depth. A negative photoresist composition comprising (a) an alkali-soluble resin, (b) an acid generator, and (c) other components is used, and a plated product is formed by (A) a step of forming a layer of this negative photoresist composition, and then either heating or not heating, before conducting exposure; (B) a step of repeating the step (A) so that the step is performed a total of 2 or more times, thereby superimposing layers of the negative photoresist, and subsequently developing all of these layers simultaneously to form a multilayer resist pattern; and (C) a step of conducting plating treatment within this multilayer resist pattern.

  • Patent number: 7318279
    Abstract: A rolled steel plate 1 wound in a roll shape is unrolled and is cut in given dimensions to form a blank 2. In this case, a cut surface 2a is caused to incline at 1 to 3 degrees relative to the thickness direction of the blank 2, wherein the inclination direction of the cut surfaces 2a, 2a on each side is reversed. The blank 2 cut in this manner is roll-formed to cause the cut surfaces 2a, 2a to confront each other. Since the cut surfaces 2a, 2a on each side incline at 1 to 3 degrees in the opposite direction as described above, the cut surfaces 2a, 2a are caused to be parallel. Then, the confronting sections are laser-welded to form a cylindrical body 3.

  • Publication number: 20070245395
    Abstract: A conventional digital video reproducing apparatus outputs a descrambling request to a descrambling processing unit also on a packet which is not needed to be descrambled. When types of inputted packets exceeds the maximum number of types of packet that the descrambling processing unit can simultaneously descramble, it is impossible for the conventional apparatus to descramble a packet to be descrambled, whereby an audio and a video are not reproduced. In contrast to this, A PMT processing section 6 deletes data on a packet of a type, that a video decoder 4 and an audio decoder 5 cannot decode, from a program map table PMT acquired from a TS decoder 3. Based on processed PMT information Ipmt processed by the PMT processing section 6, a descrambling card 2 descrambles only packets having data formats that the video decoder 4 and the audio decoder 5 can reproduce.
