Title: Digital nonlinear emphasis circuit and digital nonlinear de-emphasis circuit
Inventor: SAKAMOTO ETSURO
IPC: H04B1/62
Filed: 1991-08-27
Abstract: PURPOSE:To realize the digital nonlinear emphasis circuit and digital nonlinear de-emphasis circuit in which the effect of reflected noise is not caused without increasing a sampling frequency by combining a 90 deg. phase lead circuit and a 90 deg. phase lag circuit for a limiter. CONSTITUTION:When a digital 90 deg. phase lead circuit 3 at a post-stage of a bypass filter 1 leads the phase of a signal by 90 deg. and a 2nd digital limiter 4 limits the amplitude, harmonics are produced at a counter symmetric position. The amplitude of the reflected distortion component and is the same as that of a spectrum of the main signal in the 1st digital limiter 2 and the phase of the component is inverted to that of the spectrum. Thus, the 90 deg. phase lead circuit 3 and a 90 deg. phase lag circuit 5 are employed to obtain a reflected distortion whose polarity is inverted to that of the reflected distortion caused in the 1st limiter. When an output signal of the 90 deg. phase lag circuit 5 and an output signal of the 1st limiter 2 are added by a 1st signal adder circuit 8, the reflected distortion caused in the 1st limiter 2 is cancelled.

Title: Temperature sensor
Inventor: TOMITA YOSHINORI
IPC: G01K11/22
Filed: 1989-09-19
Abstract: PURPOSE:To obtain the temp. sensor having an excellent response speed, sensitivity, reversibiltiy, workability, and durability by adopting a gel as a reception section which is reversibly changed in acoustic characteristics according to temp. CONSTITUTION:The sensor formed by using the gel consists of, for example, a measur ing container 1, a measuring soln. 2, a transmitter/receiver 3 of ultrasonic waves, a wave front 4 of ultrasonic waves and the gel at the time of swelling. The soln. 2 passes around the gel at the temp. below the phase transfer point of the gel. The ultrasonic wave transmitter/receiver is integrated with the transmitter and the receiver and is used in switching at every provided period in many times. The central frequency thereof is specified to 1kHz to 100MHz. The acoustic impedance Z2 in the state of Fig. (a) is nearly the same as the acoustic impedance of the measuring soln. on the outside of the gel and the reflectivity is nearly zero. The acoustic impedance Z2 has the larger difference of the same impedance Z1 of the measuring liquid as the gel causes the phase transfer from Fig. (b) to Fig. (d) and, therefore, the reflectivity increases. The difference in the reflectivity is measured by the ultrasonic wave transmitter/receiver, by which the gel is detected if the measuring soln. is at a certain temp. or above.

Title: Howling prevention system
Inventor: AOKI KOJI
IPC: H04M1/60
Filed: 1985-10-29
Abstract: PURPOSE:To prevent howling over the entire frequency band by providing a band split filter and a variable attenuator to a reception input section of an echo canceller and reducing the loop gain at a band where no input spectrum exists. CONSTITUTION:A signal incoming to a subscriber telephone set 9 is subject to frequency split by and pass filters 4-1-4-n at the input section of the echo canceller. Each split frequency band signal is fed to an adder 7 via respective attenuators 6-1-6-n, summed again and after attenuation is applied via an attenuator 2 applying a flat attenuation onto the entire frequency band, the result is the reception input of the echo canceller 1. Detectors 5-1-5-n provided at each band detect the presence of the input signal spectrum at each split band and the detection output changes the attenuation of the attenuators 6-1-6-n. That is, the attenuation of a relevant attenuator is adjusted so as to have a zero or a prescribe attenuation in response to the presence of the detection of an input signal spectrum.
