Title: Delay signal processing circuit
Inventor: KOSEKI YUICHI
IPC: G10K15/00
Filed: 1988-02-03
Abstract: PURPOSE:To reduce the cost of the title circuit and to perform sufficient signal processing of high quality by simplifying an analog-digital signal conversion part and a digital-analog signal conversion part. CONSTITUTION:This processing circuit is provided with a signal converting circuit 6 equipped with a circuit means which converts an analog signal into a digital signal, mixes the digital signal with the analog signal, and reduces the mixed signal and noise generated at the time of the analog-digital conversion within a necessary band, a memory 10 which stores the serial digital signal sent out of the signal converting circuit 6 temporarily, a memory controller 9 which controls the input and output of the memory 10, and a low-pass filter 12 which removes higher harmonic components of the signal read out of the memory 10. When a delay signal of echo effect, etc., is generated, a digital signal is read out of the memory 10 at constant-time delay timing and converted into an analog signal, which is mixed with the analog input signal. Consequently, digital signal processing is performed at relatively low sampling frequency without any sample holding circuit, so the circuit is constituted at low cost.

IPC: C04B28/04
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To extend the use of a calcined cement raw material and to improve the strength after solidification by using the callcined cement raw material taken out from a preheated as a part of a Portland cement and having a specific calcining ratio. SOLUTION: The calcined cement raw material having 80-90% calcining ratio is taken out from the preheater arranged in a cement firing equipment and calcining a cement raw material. Water is added into the calcined cement raw material to partially digest quicklime portion contained in the calcined cement raw material.

Abstract: PURPOSE:To obtain a stable operation, by constituting a device in such a way that the cycle of ON-OFF-ON of a loop is neglected when the OFF state of the loop for more than a prescribed time is detected within the prescribed time from an ON state, and the operation is performed by recognizing the cycle as a DP signal when no OFF state is detected. CONSTITUTION:When the cycle (a) is stored in a loop monitoring result storage means 200a, a control circuit 200 detects the state of the loop from the start of the last ON state of the loop of the cycle, however, in such a case, no minimum pause of the ON state of the loop is detected, and adversely, the fact that the OFF state longer than the maximum time TMAX of loop OFF can be recognized. Therefore, the control circuit 200 neglects it as noise such as chattering, etc., at the time of performing the on-hook of the cycle, and disconnects a call. Also, when the cycle (b) is stored in the loop monitoring result storage means 200a, the control circuit 200 detects the minimum pause of the ON state, and since no OFF state is detected, it recognizes the cycle as the DP signal.
