Abstract: PURPOSE:To control stably even when a load abruptly changes in a speed control using selectively a clutch and a brake by storing an error signal sampling value preceding by one and raising the gain of the engaged clutch when the sampling  value is lowered. CONSTITUTION:An actual speed signal 1 is converted into a pulse train via a waveform shaper 5 in the speed control system using selectively the clutch and the brake. A revolution number indicating signal 2 is converted into a clock pulse responsive to the indicated value by a V/F converter 10, the clock pulses 7 responsive to the actual speed signal are counted and are applied to a latch circuit 13. The sampling value preceding by one held in the latch circuit 13 is shifted to the second latch circuit 17. Thus, the sampling values of both the latch circuits 13 and 17 are compared, and any of the clutch signals 3 and 4 is outputted therefrom. In this case,  when the sampling value of the circuit 13 is higher than a predetermined value, the  clutch signal 3 is produced for longer time.

Title: Digital transmission system
Inventor: TAKEMURA TETSUO
IPC: H04L25/05
Filed: 1982-01-14
Abstract: PURPOSE:To simplify an equalizing circuit and a clock pickup circuit and to mitigate the transmission line propagating time (extension of transmission line), by adjusting guard time for a terminal side only with a simple circuit, and reducing the signal transmission speed. CONSTITUTION:A selector 18 outputs a transmission signal group SG2 delayed with 3-bit(clock) corresponding to the guard time of a digital value. Thus, since a guard time t10=10mus is fixedly added to a transmission clock SCK, the guard time is a sum of two-clock added at the SCK and 3-clock, in total 5-clock's share of t7=5.92X5 30mus. In changing the length of subscriber line, the corresponding digital value is outputted from an A/D conversion circuit 15, then the control is done automatically so as to obtain the desired guard time t at all times.

Title: Arithmetic unit
Inventor: HARA YOSHIHISA
IPC: G06F17/14
Filed: 1984-01-12
Abstract: PURPOSE:To reduce the capacity of an address generating memory and the hardware of an arithmetic section, by selecting the number of basic clocks necessary for making a butterfly arithmetic of fast Fourier transformation at the power of 2, and synchronizing the address generating circuit and arithmetic section. CONSTITUTION:The number of clocks is selected as, for instance, 2<4>=16, and an address generating circuit makes the following arithmetic for synchronizing to the power of 2 of basic clocks. Change in the low-order four bits of the output of a counter 5 synchronizes to a butterfly arithmetic and the remaining higher order bits perform the n-th butterfly arithmetic at present. On the other hand, since each data can be used for arithmetic once because of the nature of an FFT and operated results can be written in the same address of a memory, from which data are read out, it is sufficient to obtain a 2-bit decoded output to a 4-bit input signal and one bit is enough to a coefficient address. Therefore, it is sufficient that decoding is made by using outputs of 16 clocks so that the outputting timing of a decoder 9 coincides with the data inputting timing and coefficient outputting timing.
