Title: Error detection circuit for variable servo controller
Inventor: HORINO MAMORU
IPC: H02P29/00
Filed: 1987-09-07
Abstract: PURPOSE:To prevent a loop gain from varying when a reference period is altered by varying a slope gradient of a reference signal in response to the reference period. CONSTITUTION:An integrator 14 charges a capacitor 20 through a variable resistor 32, and outputs a signal rising at a slope having a predetermined gradient. When a reset switch 22 is closed, its output is returned to '0'. A controller 25 closes a let switch 22 on the basis of the output timing of a speed pulse, and hold the integrated value immediately before in a sampleholding circuit 24. After the switch 22 is closed, it is again turned OFF after a predetermined time is elapsed to repeat the integrating operation. Here, the time until the integrated value arrives at V1/2 is determined as a reference period. When the reference period is altered, the controller 25 adjusts the resistor 32 and controls the ON time of the switch 22.

Title: Equalizer and stereo equalizer
Inventor: YAMASHITA OSAMU
IPC: H03G5/02
Filed: 1988-09-07
Abstract: PURPOSE:To attain a reproducing close to original sounds by changing speed with which a signal is transmitted for each register and canceling a delay on the side of a low register in the propagation of the sounds emitted from a speaker system. CONSTITUTION:A low register circuit 1 has a circuit in which transformers T1 and T2 are connected in series and the signal is transmitted by an induced current. Consequently, it is transmitted with the speed higher than the transmission speed with which the signal flows in the capacitors C2 and C3 and a register R3 of a middle register circuit 2 and a high register circuit 3. On the other hand, in the middle register circuit 2 and the high register circuit 3, the current is amplified by an amplifier A2 in the high register circuit 3. Therefore, the signal is transmitted later than the middle register circuit 2 which does not amplify the current. Thus, the sounds are emitted faster on the side of the low register and the sounds closer to natural ones can be reproduced.
