摘要： A digital broadcast receiver capable of adequately receiving a higher-level layer service along with a lower-level layer service even if the reception CNR degrades. A demodulation decoding section (2) of the receiver judges on the basis of transport and multiplexing configuration control information whether the TS packet allocated to each slot is adapted to a higher-level layer service or a lower-level layer service and informs a code writing section (3) of the result. The code writing section (3) writes, in each TS packet, a layer identification code for judging whether the TS packet is adapted to a higher-level layer service or a lower-layer service and synthesizes a resultant TS packet. A stream separating section (4) reads the layer identification code along with the PID in the packet header included in the TS packet and finds and extracts a desired TS packet.

摘要： An improved apparatus for receiving BS digital broadcast is disclosed. The apparatus for receiving BS digital broadcast of the present invention has first to third filters and a selective complex calculator circuit.Each of the first to third filters 18 to 20 identifies the modulation technique applied to the received signal, by the modulation identification signals A0, A1 received from a timing generator circuit 25, and filters a phase error signal PED according to the identified modulation technique. The selective complex calculator circuit 21 shifts the phase of a signal point indicated by an I signal ADI1 and a Q signal ADQ1 absolute-phased by an absolute-phasing section 14, by a phase corresponding to the phase error signal filtered by the first to third filters 18 to 20. At this moment, the selective complex calculator circuit 21 selects the phase error signal corresponding to the modulation technique identified from the modulation identification signals A0, A1 received from the timing generator circuit 25. Consequently, in the burst receiving, it is possible to reduce the effect on the error rate because of the signal noise of the ODU to a degree equal to that in the continuous receiving.

摘要： Frame synchronization is quickly established to acquire an RF channel in a short time. Numerically controlled oscillators 1-1 to 1-3, complex calculation circuits 2-1 to 2-3, band limit filters 3-1 to 3-3, a selector 7, a phase error detection circuit 9, a loop filter 10, and an AFC circuit 11 compose a carrier regeneration loop for removing the frequency error of the carrier included in an in-phase component I and a quadrant component Q of the baseband signal input to the complex calculation circuits 2-1 to 2-3. A timing generator 6 detects which of frame synchronization pattern detection circuits 5-1 to 5-3 has detected a frame synchronization pattern, provides the selector 7 with a selection signal corresponding to the decision result, and sends a switch signal to the AFC circuit 11. Thereafter, the carrier for removing the frequency error included in the baseband signal is regenerated to acquire an RF channel in a short time.

摘要： On the side at hand of an optical probe, a whole rotation transfer connector rotates while being supported by a ball bearing and a slide bearing and, therefore, rotation is transferred to a flexible shaft. The relative position between the flexible shaft and an optical sheath is changed in accordance with the amount of screwing of a sheath stopping member on the side at hand into an outer cylinder by an external thread portion and an internal thread portion. When the optical sheath is moved furthermore, the flexible shaft is elongated due to elastic deformation because the length of the flexible shaft is regulated by the interval between a locking part of a locking member at the tip and a shaft stopping member. A tip housing is made to contact with the locking member while tension is applied to the flexible shaft by the rear end surface in the direction of the side at hand. During the use of optical probe, even when the optical probe is curved and the inner surface of the flexible shaft is contacted with the inner surface of the optical sheath, moving of the tip housing is canceled by the elongation amount of the flexible shaft elongated in advance and, therefore, the tip housing rotates at a constant position relative to the probe longitudinal direction on all occasions.

摘要： An Optical Coherence Tomography (OCT) device irradiates a biological tissue with low coherence light, obtains a high resolution tomogram of the inside of the tissue by low-coherent interference with scattered light from the tissue, and is provided with an optical probe which includes an optical fiber having a flexible and thin insertion part for introducing the low coherent light. When the optical probe is inserted into a blood vessel or a patient's body cavity, the OCT enables the doctor to observe a high resolution tomogram. In a optical probe, generally, a fluctuation of a birefringence occurs depending on a bend of the optical fiber, and this an interference contrast varies depending on the condition of the insertion. The OCT of the present invention is provided with polarization compensation means such as a Faraday rotator on the side of the light emission of the optical probe, so that the OCT can obtain the stabilized interference output regardless of the state of the bend.
