    摘要: A mobile radio communication apparatus includes a switch which outputs a strength of a received radio frequency signal or a power strength of a radio frequency signal in accordance with an input of a switch control signal supplied from a switch control circuit. The switch control signal is supplied during a transmission time slot allotted to the mobile radio communication apparatus by the base station so that the switch outputs the power strength of the radio frequency signals in the same period of the transmission time slot and the strength of a received radio frequency signals in the same period of an other time slot. The strength of the received radio frequency signals and the power strength of the radio frequency signals are supplied to an analog-to-digital converter which converts the applied signal into a digital signal and supplies the digitalized signal to a level detector. The level detector detects a level of the strength of the radio frequency signals and a level of the power strength of the radio frequency signals which are used for monitoring condition of a transmission and a reception of the radio communication apparatus.

    摘要: In a digital communication apparatus, when a slot is received by a transmission system, two different data included in the received slot are stored in two data storage circuits, respectively, by a predetermined amount, and are read out therefrom at different times, that is, time-divisionally. An error in the data having different transfer formats read out from the two data storage circuits is detected by a CRC data decoder formed of a single circuit based on a detection code such as CRC (cyclic redundancy check) code.

    摘要: A power transmission belt having longitudinally spaced pairs of blocks on the opposite surfaces of a neutral belt portion thereof. The blocks are formed of hard synthetic resin materials having fibers distributed therein. The fibers may be provided in the form of distributed short fibers, fabrics, and one or more different types of fibers may be utilized in the respective blocks. The fibers include carbon fibers, aramid fibers, and silicon carbide fibers. The neutral belt is provided with longitudinally spaced projections on the upper and lower surfaces thereof and the blocks are provided with complementary recesses receiving the projections. The recesses are preferably deeper than the height of the projections, whereby the distal surfaces of the blocks may be urged with high frictional engagement against the flat surfaces of the neutral belt. The blocks are resiliently clamped to the neutral belt and the clamping forces are urged through the neutral belt to the tensile cord carried therein for further improved stabilization of the blocks on the neutral belt.
