Title: Loud speaking device
Inventor: MATSUMURA FUMIHIKO
IPC: H04R3/02
Filed: 1986-06-20
Abstract: PURPOSE:To prevent the growth of a howling tone to suppress howling by providing a notch filter and a control circuit, which scans the center frequency of the stop band of this filter in one direction of the frequency base, between a microphone amplifier and a power amplifier and allowing the input signal from a microphone to pass the notch filter. CONSTITUTION:The output of a microphone 1 is amplified by a microphone amplifier 2 and is inputted to a notch filter 3. A control circuit 4 of the notch filter 3 scans the center frequency of the stop band of the notch filter 3 from the low band or the high band to the high band or the low band at a certain period T to control it. The output of the notch filter 3 is amplified by a power amplifier 5 and is inputted to a speaker 6. Since the signal in each band is attenuated with the notch filter at the certain period T by such operation, the growth of the howling tone in a specific frequency is prevented.

CONSTITUTION:The value (maximum vector length -1) of a vector register 1, i.e., 63 is set fixedly to a maximum vector length register 7. In the case of an instruction for reading the maximum length of the register 1, a scalar register 4 designated by 8-11 of an instruction is selected. Then the contents of the register 7 are loaded to the selected register 4. The value loaded to the register 4 is used in a series of processes. When a vector arithmetic instruction is executed, the vector elements designated by an instruction and given from the register 1 are read out successively. These elements are executed by an arithmetic unit 3, and these arithmetic results are stored consecutively to the register 1. In this case, the vector operands to be executed are equal to the frequencies set previously at a vector length register 2.

Title: Data recording apparatus
Inventor: KOSUGE WATARU
IPC: G11B27/28
Filed: 1977-12-02
Abstract: PURPOSE: To accurately reproduce the recording medium of varying recording and  reproducing speed in a Frequency Shift Keying system by detecting the ratio of the  two reproduced signals which are separated by the superposed record of reference  signals.  
     CONSTITUTION: The reference signals of frequency f 0  of a reference signal generator 4 are superposed upon the recording signals of frequency f 1  from a signal source 1 so that they are recorded in a recording medium such as a magnetic tape. If the reproducing speed is varied for the recording speed, the frequency of the reproduced signals is varied with the variation in the reproducing speed so that the frequencies of the recording and reference signals separated by a band filter become (1+Δ)f 1  and (1+Δ)f 0 . If the ratio of the frequencies of the two signals is detected by an AND gate, the variation is cancelled. If the processing is carried out with the use of an OR gate or the like, it is possible to accurately produce the information corresponding to the initial signal frequency.
