Abstract: An error detecting device and method for use when applying the Viterbi decoding to an inputted signal, when it is necessary to derive the number of errors included in a decoded signal. A value of a path metric derived upon the Viterbi decoding is read out and outputted as the number of errors. Two kinds of decoding devices, each reading out a value of a path metric and outputting this value as the number of errors, are provided for a sound signal and an FACCH signal. A signal is inputted to both devices for decoding, respectively. The numbers of errors derived from both devices are compared, and it is judged based on a result of the comparison, whether the inputted signal is the sound signal or the FACCH signal.

Abstract: A decoder receives frames of data that have been block coded, then convolutionally coded, at a rate of multiple frames per block. As each frame is received, the decoder counts it, stores convolutional code path information, and updates metric values pertaining to the paths. Once per block of frames, the decoder selects a path having the best metric value, convolutionally decodes one block, detects errors from both the block code and path metric, and generates error information. From the error information, the decoder decides whether block synchronization has been acquired or lost, and clears, decrements, or sets the frame count accordingly. If synchronized, the decoder outputs the block and its error information, and updates the path memory in preparation to decode the next block. Otherwise, the decoder prepares to reacquire block synchronization.
Abstract translation: 解码器以每块多个帧的速率接收已被块编码的数据帧，然后进行卷积编码。 当每个帧被接收时，解码器对其进行计数，存储卷积码路径信息，并更新与路径有关的度量值。 每块帧一次，解码器选择具有最佳度量值的路径，对一个块进行卷积解码，从块码和路径度量中检测错误，并产生错误信息。 从错误信息中，解码器判定是否获取或丢失块同步，并相应地清除，减少或设置帧计数。 如果同步，解码器输出块及其错误信息，并准备更新路径存储器以解码下一个块。 否则，解码器准备重新获取块同步。

Abstract: An equalizer including a channel estimator allowing a Viterbi algorithm processor to estimate transmitted symbols accurately, so that the impulse response of a transmission channel may not deviate from the correct one. The equalizer outputs an transmitted symbol sequence estimate having the largest path metric by correcting the channel impulse response by parameter coefficients of the LMS (Least Mean Square) or RLS (Recursive Least Square) algorithm, by compensating for phase fluctuations due to the frequency offset and phase jitter of received signals, or by using a sequence included in an intermediate portion of a TDMA (Time Division Multiple Access) frame format.

Abstract: In an electric motor-driven booster, a sharp change of reaction force to an operation of a brake pedal is reduced to improve the brake pedal operation feeling. Operation of the brake pedal causes an input rod (34) and an input piston (32) to advance, and an electric motor (40) is driven according to the movement of the input piston to propel a primary piston (10) through a ball-screw mechanism, thereby generating a desired brake hydraulic pressure in a master cylinder. At this time, the input piston receives the hydraulic pressure in the master cylinder to feed back a part of reaction force during braking to the brake pedal. When the brake pedal is further depressed after the output of the electric motor has reached a maximum output and the primary piston 10 has stopped, a lock nut abuts against a movable spring retainer and compresses a reaction force spring.

Abstract: A pinion gear unit includes a rotation member rotating according to the rotation of a output shaft. A first pinion gear fit to the rotation member through a first serration unit rotates with, and also moves with the rotation member if the pinion gear unit moves towards an engagement location with an engine starting gear. A second pinion gear is fit to the rotation member adjacent to the first pinion gear through a second serration unit, rotates with and moves with the rotation member if the pinion gear unit further moves towards the engagement location, and engages with the starting gear later than the first pinion gear, where the first pinion gear engages with the engine starting gear. Fitting is performed by the first and second serration units so that phases of teeth of the first and second pinion gears in a circumferential direction correspond with each other.

Abstract: Provided is an engine starter wherein a torsional angle θ1 of a helical spline 4a of an output shaft 4 is set in such a way that a reactive force Fp1 of a plunger spring 33, which is operated to a clutch 5, is larger than a propulsive force F, which is operated so as to urge the clutch 5 by a rotational force of the motor 2 in a shaft direction along a helical spline 4a of an output shaft 4, before a pinion engaging solenoid 8 is operated. Thereby, it can be prevented that the clutch 5 is urged in the shaft direction, so that it can be prevented without upsizing the engine starter that the pinion 6 is protruded in the shaft direction.
