Abstract: A digital broadcast channel reception system and a portable terminal allow watching a digital broadcast on the terminal. In the examples, a receiver unit for receiving digital broadcasts transmits video data to a display unit, using its TX data manipulator, modulator, TX circuit, and antenna. The TX data manipulator manipulates the output from an OFDM demodulator into data to transmit from the TX circuit and appends error correction codes to the data. The modulator modulates the output from the TX data manipulator. A display unit for digital broadcast display receives video data transmitted from the receiver unit, using its antenna, TX/RX section, and modulator/demodulator. After error correction codes in the received signals are decoded by a TX/RX data manipulator, video data is extracted. After the video data is decoded by a MPEG4 decoder, a picture is output on the display.

Abstract: A clutch drum 15 is configured to reduce the weight of a clutch drum while keeping the mechanical losses of the clutch drum 15 in check. The clutched drum 15 houses several clutch plates 17 and has a cylindrical part 23 and a plurality of the teeth 25 that are arranged circumferentially around the inside of the cylindrical part 23 and extend in the axial direction. The teeth 25 have tooth cusps 29 and tooth flanks 31 on both rotational-direction sides. Bottom lands 35 are formed on the inside surface of the cylindrical part 23 between the teeth 25 in the axial direction. The outside recesses 37 are formed on the portions of the outside surface of the cylindrical part 23 that correspond to the teeth 25 and the inside recesses 27 are formed on the inside surfaces of the teeth 25.

Abstract: A frictionally engaging clutch disc assembly includes portions which define alignment holes which are employed during assembly of the clutch disc assembly. A tooling jig having alignment pins are engaged in the alignment holes such that the various portions of the clutch disc assembly arc accurately positioned with respect to one another during construction of the clutch disc assembly.

Abstract: A clutch disc assembly is provided with a support structure and friction generating members that provide generally constant friction generation, even when misalignment occurs between adjacent members. The clutch disc assembly 1 includes a hub 2, a fourth friction washer 19, a clutch plate 3 and a second coil spring 7. The fourth friction washer 19 is fixed to the hub 2 and has a tapered surface 19a. The clutch plate 3 has an inner peripheral edge tapered portion 3c which is abutted against the tapered surface 19a and disposed on the outer periphery of the hub 2. The second coil spring 7 couples the hub 2 to the clutch plate 3 in a circumferential direction.

Abstract: A clutch disc assembly holding a diaphragm spring using a pair of wire rings clamped by bent tabs of a clutch cover or stud pins, and having a coned disc spring for controlling an increase in a releasing load due to wear of facings of a clutch. An annular coned disc spring urging an outer peripheral portion of the diaphragm spring to a side opposite to the clutch disc is disposed between a pressure plate and the diaphragm spring. An annular support plate is provided and its inner peripheral portion is held between the bent tabs of the clutch cover and the pair of wire rings. The coned disc spring is held by an outer peripheral portion of the support plate and the outer peripheral portion of the diaphragm spring in an elastically deflected condition.

Abstract: A manufacturing method for a disk-like diaphragm spring for making a center hole at a center part, making rectangular holes on an outer peripheral part with specified spaces left between such holes in a circumferential direction, forming plural ligulated fingers radially by means of plural radial slits extending from such rectangular holes to the center hole and inner peripheral parts of the fingers to be pressed by a release bearing. The method comprises a step of punching such rectangular holes and slits out of a disc-like blank with a press and forming between the slits tapered ligulated fingers and a process of punching out a center hole by using a gear-shaped press die having circular tip portions at the same spacing as the slits for forming tapered openings at the slits extending radially outward from the center hole slits and circular ends on the fingers.
