Abstract:
A content search device calculates the number of valid encrypted contents as comparison objects contained in encrypted content databases and the number of valid decryption keys contained in decryption key databases. The database having the smaller number is decided to be a reference database. By successively reading out entries contained in the reference database, a combination of an encrypted content and a corresponding decryption key is searched.
Abstract:
A ridge stripe type semiconductor laser device is provided, on a semiconductor substrate (102), with a first conduction type cladding layer (103), an active layer (104), a second conduction type first cladding layer (105), a second conduction type second cladding layer (108) of a ridge type stripe shape for confining direction, and a current block layer (107) formed by removing at least an upper portion of the ridge. In a section normal to the stripe direction of the ridge, each of the two side faces of the ridge is provided with a first face (118) substantially normal to the semiconductor substrate surface and extending downward from the upper end of the ridge, and a second face (119) formed to have a substantially straight skirt slope face inclined at the ridge skirt portion obliquely downward to the ridge outside. The first face and the second face are made to merge either directly or through a third intermediate face into each other. A face (111) of a semiconductor constituting the second cladding layer is exposed to the second face. The semiconductor laser device thus provided can have a high kink level and a high output with a low operating current.
Abstract:
There are provided a base station device and a mobile station device for increasing the speed of cell search by introducing identification of TTI timing into the cell search. In the base station device (100), a frame configuration unit (120) forms a frame by arranging a TTI synchronization sequence (SCH1 sequence) used for identifying the frame timing and a TTI synchronization sequence (SCH2 sequence) used for identifying the TTI timing in such a manner that they are not superimposed on the same symbol specified by the frequency and the time. A radio transmission unit (145) sends the frame. The frame configuration unit (120) arranges the frame synchronization sequence at a predetermined position from the frame starting symbol and the TTI synchronization sequence at a predetermined position from the TTI starting symbol. The mobile station device (200) receiving the frame detects the TTI timing by using the TTI synchronization sequence.

Abstract:
When a certain period of time has elapsed since a direction retrieval unit received a control signal from an appliance controller, the direction retrieval unit instructs the microwave transmitter to transmit microwaves, and then instructs the microwave transmitter to perform scanning of the microwaves. When a notification signal receiver receives a notification signal from a remote controller, the direction retrieval unit instructs the microwave transmitter to stop the scanning of the microwaves. After this, the direction retrieval unit instructs a power controller to raise a power level of the microwaves. The direction retrieval unit determines whether or not the notification signal receiver receives from the notification signal transmitter of the remote controller at regular time intervals charging-in-progress signals indicating that charging is in progress and whether or not the notification signal receiver receives from the notification signal transmitter a charging-complete signal indicating that the charging is completed.

Abstract:
Provided is a multicarrier communication apparatus by which information quantity of CQI reporting can be reduced. In the apparatus, each CQI is recorded in a CQI table section (122) by being classified into a plurality of CQI groups by following a certain rule. A CQI selecting section (123) estimates fluctuation range and variance of reception qualities of the entire resource block to be reported, based on an SINR value outputted from a quality level calculating section (121). Then, based on the estimated values, the CQI selecting section selects a suitable CQI group in a first step, selects a suitable CQI value from among the CQIs included in the selected CQI group in a second step, and outputs the ID of the selected CQI group and the selected CQI value to a CQI generating section (124) . Based on such information, the CQI generating section (124) generates a CQI frame to be transmitted to a base station.
Abstract:
The present invention provides a surface mounted semiconductor device 1 formed by cutting an assembly board together with cathode wiring patterns 8 and anode wiring patterns 10 arranged on the assembly board on which light-emitting elements are mounted. When the surface mounted semiconductor device 1 is mounted on a mounting board with the cutting plane (bonding surface) facing the mounting board, the cathode wiring patterns 8 serve as cathode connection electrodes 15 and the anode wiring patterns 10 serve as anode connection electrodes 12. A substantially semi-elliptical notch 16 is formed in each of the anode connection electrodes 12. A substantially fan-shaped notch 14 is formed in the corner of each of the cathode connection electrodes 15. Thus, it is possible to provide a surface mounted semiconductor device that can prevent a poor connection and ensure the bond strength by forming a solder fillet reliably, even if burrs are produced on the connection electrodes formed by cutting the assembly board.
