Title: Digital signal encoding and decoding device and method
Inventor: MAIKERU JIYOOJI BEIRUUCHI
IPC: G10L19/04
Filed: 1984-11-29
Abstract: In a method and apparatus for coding of digital signals, especially so-called "waveform" coding of voice frequency signals to reduce bit rates for reduced transmission or storage requirements, in which, for each block, an excitation signal is derived which, when applied to be a synthesis filter having suitable LPC coefficients, will generate an approximation to the input signal, low signal delay is achieved by deriving such excitation signal using the LPC coefficients corresponding to the last sample period of the corresponding block. Thus the excitation signal calculations in the encoder need only be delayed by the duration of the block. The LPC coefficients can be derived on a continuous or sample-by-sample basis using an adaptive lattice. Simplified computation of the excitation signal, which comprises a set of pulses fewer in number than the number of samples in the original block, may be achieved by cross-correlating the impulse response of the modified synthesis filter with the output of the filter and using the result, together with the covariance of the impulse response, to derive the parameters of the excitation pulses. Further computation simplifications may be achieved by using an auto-correlation as the covariance signal.

Abstract: PROBLEM TO BE SOLVED: To stabilize the rotation of a rotary body having a center of gravity which is eccentric from a rotary shaft of a rotary shaft body even though the position of the center of gravity under rotation is changed by adjusting the distribution of compositions. SOLUTION: A stabilizing mechanism is composed of a damper 4 adapted to be elastically deformed by a centrifugal force of a rotary body 1 provided between a rotary body 1 and a rotary shaft body 2, during rotation, and balancers 6 built in a balance casing 5 provided along the outer peripheral edge of the rotary body 1, and adapted to be displaced along the inner wall of the balance casing 5 in response to a deflection of the rotary body 1 caused by the elastic deformation of the damper 4. With this arrangement, the centrifugal force caused by the center G of gravity can be cancelled out by the centrifugal forces of the balancers 6 which are displaced and crowded on one side of the rotary body 1, thereby it is possible to reduce the deviation of the center G of gravity.

IPC: H02H3/347
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction due to a heavy transient current by providing a switch element for isolating the contacts of a circuit breaker for AC current with a leakage detection signal from a leakage detection circuit and a locking means to prevent application of the leakage detection signal with a lock signal from a lock signal leading means. SOLUTION: An input signal from an A/D converting circuit 12 is judged whether it is an input signal of an unbalanced region. When result is YES, whether earth leakage is generated or not is judged from the level of input signal detected by a detection resistance 44. When it is judged that earth leakage is not generated, a lock signal is output to prevent operation of the switch element 4 and isolation of contacts of circuit breaker due to output error of the earth leakage detection circuit 3 can be prevented. If it is judged that earth leakage is generated, output of the lock signal 13b is immediately stopped not to impede the output to the switch of the earth leakage detection signal 3a. Thereby, malfunction due to the transitional heavy current may be prevented.

IPC: G06F12/06
Filed: 1991-09-30
Abstract: PURPOSE:To allow this memory system to flexibly cope with various memory ICs by comparing a system address with memory area information and forming a memory block selecting signal. CONSTITUTION:The memory system is provided with a memory area register (not shown) in which the upper and lower limit address values and block sizes of respective memory blocks are set up.
