IPC: H03H15/00
Filed: 1982-03-02
Abstract: PURPOSE:To approximate an error to the logic limit, by using a training signal which is produced by an orthogonal system having a period equal to or larger than the number of taps. CONSTITUTION:A transversal filter 2 having variable weight receives a training signal generated from a terminal 1 through an orthogonal system having a period N. A signal detector 3 detects the arrival of the head of the training signal and at the same time applies a trigger signal to a delaying element 4. The element 4 starts a counter 5 and a Kalman algorism processor 6 at one time. The processor 6 replaces successively the tap weights of a filter 2 by the clock which is produced by a clock pulse generator 7. The counter 5 delivers an operation stop pulse to the processor 6 and at the same time starts a gradient algorism processor 8. Then the processor 8 replaced the tap weight.

Title: Re-circulating control method for pump
Inventor: OOTSUKA MASAHIRO
IPC: F04B49/06
Filed: 1978-03-23
Abstract: PURPOSE: To prevent re-cycle valve chattering by setting a limit to a re-cycling control signal so that the re-cycle valve may be kept open to a certain degree until the suction rate reaches a fixed rate.  
     CONSTITUTION: While the load on a boiler is small and the flow rate of water supply is sufficiently smaller than the fixed value fMIN of the suction rate of a water supply pump BFP, the output signal of a control arithmetic unit COM becomes maximum and the opening of a recycle valve VLV is controlled symmetrically to the increase and decrease of supply rate of water into the boiler so that the suction rate of the water supply pump BFP is controlled to be equal to the fixed rate fMIN. As the water supply into the boiler increases, the output signal of the controlarithmetic unit CON decreases, decreasing the opening of the re-cycle valve VLV. However, when the output signal value of the control arithmetic CON becomes less than the opening α%, the output signal α is selected by a maximum value selector SEL to keep the opening of the re-cycle valve VLV larger than α%. Thus, chattering is prevented.

Abstract: PURPOSE:To provide a high speed read signal similarly to a static memory cell by constituting a 3 MOS type memory cell of an amplifying MOSEFT. CONSTITUTION:When the read operation of a storing memory array 1 is performed and a signal of an address different from the address stored in an address register 8 as the word line selection circuit of a high speed memory array 3 is inputted, an address comparator 8 forms a mismatching signal, and selects a word line of the array 3, and amplifies it with a sense amplifier 2.

Thus, output path of a Y system is shared with the arrays 3, 1, and a circuit is simplified, and further, since the data of the array 3 are controlled and the priority is set, memory access is accelerated.
