Title: Noise reduction device such as alle-duplex speaker phone and method
Inventor: SANGIRU PAAKU
IPC: H04B3/23
Filed: 1993-11-05
Abstract: PURPOSE: To reduce noise during calling and to eliminate initialization node by a signal processing system for the full-duplex speaker phone, etc. CONSTITUTION: Delay before filtering is determined according to a first attack time and the tap length of an adaptive echo canceling filter is determined according to the number of sample cycles between the first attack and the time when the mean electric power of an echo decreases below a threshold value. A coefficient of each microphone 140 is initialized and an initial filter coefficient generated by the initialization is held in a corresponding nonvolatile memory 104 to evade an initialization sequence. In response to an on-hook signal, the coefficient is read out of the nonvolatile memory. Coefficients are continuously updated during operation and when another microphone 141 operates, the coefficient stored corresponding to the microphone dynamically replaces the current coefficient.

Title: Musical sound control method for electronic musical instrument
Inventor: USA SATOSHI
IPC: G10H1/053
Filed: 1988-11-28
Abstract: PURPOSE:To easily control a musical sound at a high speed by controlling the harmonic parameter of a musical sound by fuzzy reasoning according to play information. CONSTITUTION:A parameter reasoning circuit 5 reasons the harmonic parameter for determining a harmonic constitution rate according to an input signal and outputs it to a sound source circuit 6. The sound source circuit 6 generates a musical sound according to the parameter, a key code, and a key-on signal. In this case, the harmonic parameter of the musical sound is controlled by fuzzy reasoning according to the play information. Namely, the pitch parameter is controlled by fuzzy reasoning by referring to the play information (key-on signal, initial touch strength, after-touch strength, etc.) in combination. The fuzzy reasoning is performed as to 'How much the harmonic constitution is set according to various play information?'. Consequently, even when fine harmonic constitution is controlled, the control is performed by the simple circuit constitution without decreasing the processing speed.

CONSTITUTION:An optical head 4 is moved in the radius direction of a magneto- optical disk circular plate 1 with being interlocked with an electro-magnet 7 for auxiliary magnetic field 7 and the overlapping writing can be executed by a laser pulse and the polarity of the auxiliary magnetic field. These operation is synchronized to a system clock 10. A duty correcting circuit 16 is added to this conventional system. The circuit 16 obtains recording data 15 and the system clock 10 as an input and the circuit 16 is operated by the command of a system controller 12. The recording data are converted to an output to be extended only by the half cycle period of a laser beam clock by the circuit 16. Thus, the beam is not impressed to the opposite polarity just after the polarity of the magnetic field at a recording time, namely, at an erasing time and one part of the record is prevented from being erased. As the result, the satisfactory overlapping writing is obtained.

Abstract: PROBLEM TO BE SOLVED: To adjust pressure with high accuracy in a manner such that a detecting means for detecting the pressure of an upper-half molding die to a lower-half molding die is provided between a fixed member fixed to a tie bar on the other side of the side on which the lower-half molding die is provided so as to accurately detect the pressure of the molding die. SOLUTION: An upper-half molding die 5 is provided below a moving platen 4, and a lower-half molding die 6 is provided above a lower platen 2. A lower fixed nut 11 is fixed to a tie bar 3 on the opposite side of the side on which the lower-half molding die 6 is provided. A load cell 12 for detecting the pressure of the upper-half molding die 5 to the lower-half molding die 6 is provided between the lower fixed nut 11 and the lower platen 2.
