Title: Tape recorder
Inventor: MORISHITA HIDEO
IPC: G11B5/027
Filed: 1989-01-25
Abstract: PURPOSE:To prevent the mixing with a regenerative signal at the time of recording with a built-in microphone by muting an output signal of a reproducing dedicated head only when an editing function selecting switch is changed over to the side of the built-in microphone. CONSTITUTION:An input signal of the built-in microphone 4 is inputted through a recording amplifier 8 to a recording and reproducing heads 3 via a recording/ reproducing changeover switches 7-2 and 7-4 and recorded. At this time, an output signal of the amplifier 8 is connected with an amplifier 10-1 as well, but since a Vcc voltage is connected with the amplifier 10-1 via a recording/ reproducing changeover switch 7-5 and the editing function selecting switch 9, a sound signal is not outputted to a speaker. Then, the Vcc voltage is also connected to muting transistors 6, and at the time of recording with the microphone 4 only, outputs of reproducing head amplifiers 1 are muted. By this method, at the time of recording with he built-in microphone, the mixing with the regenerative signal can be prevented.

Title: Device for diagnosing deterioration of operational amplifier
Inventor: INUSHIMA HIROSHI
IPC: G01R29/26
Filed: 1987-01-26
Abstract: PURPOSE:To diagnose deterioration without detaching an operational amplifier from a printed board, to facilitate the diagnosing operation, and to shorten the diagnosing time by displaying the result of comparison between the power spectrum density of a signal and a reference value. CONSTITUTION:When the operational amplifier 1 as the object of deterioration diagnosis is connected to a power source and an input signal is held at zero, the amplifier 1 outputs an internal noise signal, which is supplied to a computing element 5 through a BPF 3 and an amplifier 4 to calculate the density (dispersed value) of a noise power spectrum. A comparison reference setter 7, on the other hand, sets a value twice as large as the noise of a normal operation amplifier as a comparison reference value. Then a comparator 6 judges the deterioration of the amplifier 1 when the output dispersed value of the computing element 5 exceeds the comparison reference value and displays the result on a display device 8.

Filed: 1989-01-25
Abstract: PURPOSE:To estimate the dead time of a system by obtaining a tentative deciding model for dead time based on the system gain, a time constant, and the tentative dead time that is possibly included in the system. CONSTITUTION:In the case the gain and the time constant of a system are unknown, a parameter arithmetic means 4 computes the parameter of a time series model from the fetched input/output data. Based on this parameter, the approximate gain and time constant are obtained. At the same time, the tenta tive dead time of the system is calculated. Then a tentative dead time deciding means 6 produces a tentative deciding model for dead time based on the calcu lated dead time, the known or estimated gain, and a time constant. The output of the produced model is calculated to the stored input data. Then the error between the calculated output and the stored output data is evaluated by an error evaluating means 9. As a result, a dead time tentative deciding model is selected to secure the least error. Then the decided dead time is estimated as the dead time of the system.
