Filed: 1990-06-07
Abstract: PURPOSE:To surely expand the due data even when the level becomes suddenly lower than before by obtaining a coefficient based on the decision whether the input data should be expanded or not after this data is once stored in a memory and then taking the data out of the memory in order to obtain the product with the coefficient. CONSTITUTION:A DSP 10 fetches successively the digital data Din and writes them into a memory 2. Then the change of the values of a series of data fetched by the DSP 10 is detected. When this change is detected, the address data AST of the memory 2 storing the digital data DST on the changing point is outputted to a DSP 20 together with the data DST. The DSP 20 decides a coefficient based on the fast and last values of the data (data train) in an area divided by an AST and the prescribed value. This decided coefficient is stored in response to the data string. Then the data are red out of the memory 2 and the product is obtained with the coefficient corresponding to the data string to which the read-out data belong. This obtained product is supplied to a D/A converter 3 and an output signal Sout is generated by expanding the level of an input signal Sin.

IPC: G06F1/04
Filed: 1984-07-19
Abstract: PURPOSE:To reduce the operating time of the titled circuit by generating a differentiated pulse signal of an input signal synchronously with a referenced clock signal so as to control the change point of time of the clock signal for operating a logical circuit being an output of a frequency division circuit. CONSTITUTION:A referenced clock signal 6 is frequency-divided by a J-KFF9 and inputted to a logical circuit 1 as a clock signal 7. On the other hand, the input signal 10 in synchronizing with the signal 6 is delayed by one clock by a D-FF11 and inputted to the circuit 1. A differentiation pulse signal 13 of the signal 10 is generated by a NAND gate 12 at the same time and inputted to a J terminal of the FF9. When the signal 10 is changed by the trailing edge of the signal 7, a waveform where the leading edge of the signal 7 is delayed by one cycle's share of the referenced signal 6 is obtained and when the signal is changed at the leading edge, the signal 7 is outputted while not being modified. As a result, the signal 14 inputted to the circuit 1 is detected in terms of operation in synchronizing with the signal 7. Thus, the operating time is reduced.

Filed: 1979-11-20
Abstract: PURPOSE:To reduce the processing time and to improve the processing preciseness, by fluctuating the honing processing pressure between zero or a very small value and a cutting processing pressure during the procession of a dimeterically internal part. CONSTITUTION:Before the processing, honing rapid expansion is carried out under a prescribed pressure 7 for a period t1 to dress the grind stone 4 and to cut a certain degree. After this, a cutting pressure 8 is lowered to cut for a period t2. After the lapse of this period t2, the pressure is lowered to a pressure as shown by the reference numeral 9 to smooth the cut diametrical internal surface for a period t3, and then the pressure is lowered to zero or a minute pressure 10, when the cutting of the grind stone 4 against the work 1 becomes zero or a minute amount, so that the processing stress is released and the processed internal diameter is stabilized. Finally, without relating to the previously repeated cycles the pressure is lowered to a pressure 12 for a period t4 to finish the work so that the honing for the work 1 may be completed.

Title: Bias circuit for differential amplifier
Inventor: OGASAWARA KAZUO
IPC: H03F3/45
Filed: 1981-09-22
Abstract: PURPOSE:To perform stable operation against a negative power supply fluctuation of a differential amplifier circuit of the same phase feedback, by supplying a power supply of a bias circuit from a ground potential terminal. CONSTITUTION:To a differential amplifying circuit consisting of MOS transistors(TRs) TR12, 15, 16 and 18 connected to a positive power supply 1 and a negative power supply 2 and an in-phase feedback circuit consisting of TRs 10, 11, 13, 14, 17 and 19, a bias circuit consisting of TRs 8, 9 to which the power supply is applied from a ground terminal 20 is connected. If a negative power supply is fluctuated positive, since the gate-source voltage of the TRs 8, 9 is decreased,a current flowing to the TRs is decreased. The reduction in this current gives similar change to a current mirror TR10 to decrease the bias current of a TR19 and the gate-source voltage of the TR19 is decreased. Through the fluctuation of a negative power supply voltage to positive voltage, the substrate effect of a TR17 is decreased and an output impedance of the TR17 is increased. Thus, the gate-source voltage of a TR11 is decreased and stabilized through the in-phase feedback.

Title: Zeroing method using speed-dependent disturbance estimating observer
Inventor: TORII NOBUTOSHI
IPC: G05B13/04
Filed: 1989-06-15
Abstract: PURPOSE:To improve the transient characteristic in a low speed state by changing the feedback gain of the estimated disturbance in accordance with a command speed or the actual speed of a motor. CONSTITUTION:A motor control system has a position loop including a speed loop and a current loop as the minor loops. A current command, i.e., a torque command to be outputted to a motor is referred to as (I) together with the actual speed of the motor referred to as (v). A disturbance estimating observer 5 estimates the disturbance TL. An item 3 of a parameter outputs the value (y) corresponding to the estimated disturbance. Then the value (y) is turned into the value (y') by a gain control means 4 and subtracted from a power supply I. Thus the disturbance TL is eliminated. The means 4 changes its gain in response to the speed (v) in order to improve the transient characteristic in a low speed state.
