Title: Echo signal eliminating device
Inventor: YAMADA AKIYOSHI
IPC: H04B3/23
Filed: 1984-11-20
Abstract: PURPOSE:To make talking stable by using an AND output between an inverting signal obtained from overlapped talking detection and a signal obtained from a reception signal via the 1st and 2nd monostable multivibrator circuits for the adaptive control of an echo canceller to reject noise at overlapped talking. CONSTITUTION:An overlapped talking detector 11 detects an overlapped signal by using a transmission signal and a reception signal from a microphone 1, the overlapped signal is inverted by an inverter 7 and fed to an AND circuit 6. Further, a comparator 12 compares the reception signal with a reference signal, delayed by a prescribed time at the 1st monostable circuit 10 and differentiated by a differentiation circuit 9. The differentiation output of the circuit 9 is fed to the 2nd monostable multivibrator circuit 9 to retard the signal by a time suitable for an echo canceller 3 and the result is fed to an ANd circuit 6. Then the inverting signal of the overlapped signal and the output of the circuit 8 are ANDed by the AND circuit 6, the result is fed to an adaptive start/stop terminal of the echo canceller 3 to reject effectively the noise at overlapped talking.

Abstract: PROBLEM TO BE SOLVED: To prevent nozzles from being clogged by providing slits for flying an ink, the nozzles arranged opposite to the slits and ink channels for storing the ink which communicate with the nozzles, and further, providing an energy generator for discharging the ink in each of the ink channels. SOLUTION: The ceiling wall 26a and the lateral wall 26b of a piezoelectric member 26 are inwardly deformed in a curved form respectively by applying a pulsed voltage to a piezoelectric member 26. Consequently, an ink stored in the internal ink channel 28 of the piezoelectric member 26 is discharged into an ink fountain part 20 from a nozzle 30 under pressure. Thus an ink droplet is flown from an ink face formed in a slit 18 to stick to a recording medium and an image is recorded on the recording medium. The ink is replenished into the ink channel 28 from an ink common chamber 38 through an inlet 40 under a negative load to be generated following the restoration of the piezoelectric member 26 to its original shape by removing the application of voltage to the piezoelectric member 26. Finally, the ink is supplied into the ink fountain part 20 form an ink supply path 24.

Title: Method for preventing reflecting wave of piezoelectric substrate
Inventor: KOBAYASHI KAZUYASU
IPC: H03H9/25
Filed: 1994-10-11
Abstract: PURPOSE: To improve the performance by adhering a sound absorbing material to the entire end face in the broadwise direction in the piezoelectric substrate so as to prevent the reflecting wave thereby improving ripple and out-band attenuation. CONSTITUTION: A piezoelectric substrate 3 is fitted in the inside of a recessed part of a package 2 and a sound absorbing material 4 (silicon group adhesives) is adhered to the entire end face in the broadwise direction. Thus, a surface acoustic wave generated in an electrode pattern 6 and leaked to the outside is absorbed by the sound absorbing material 4 at the end face of the piezoelectric substrate 1, the reflection at the end face of the substrate is prevented, resulting that a ripple is prevented and out-band attenuation is improved. When the wavelength of the signal is short, the surface acoustic wave is diffused by small roughness at the end face of the substrate, the reflection is prevented and when the wavelength of the signal is long, the roughness at the end face of the substrate is too fine to diffuse the surface acoustic wave. According to the reason, the frequency at a VHF band (30 to 300MHz) is optimum. Moreover, wire bonding is easily conducted by assembling the assembly into the package.
