Title: Echo canceler device
Inventor: TAKADA SHINSUKE
IPC: G10L21/0208
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To further improve echo elimination characteristics without depending on the quality of a background noise by detecting a boundary tap position between a tap coefficient which is strongly influenced by a background noise component and a tap coefficient which is weakly influenced by the background noise component, switching a step gain before and after the boundary tap position and updating the tap coefficient of an adaptive filter. SOLUTION: An adaptive filter 10 forms a pseudo echo signal Y' (n) on the basis of a sample group of a receive signal X (n) from an A/D converter 2 and eliminates an echo component contained in a signal Y (n) outputted from an A/D converter 6 in an echo compensation adder 7. A noise canceler 19 estimates a background noise and executes a component elimination by a frequency subtraction method or the like. An updating residual difference selector 20 judges the amount of the background noise component and the boundary and makes a value of a step gain execute a selective generation of either big or small. The adaptive filter 10 optimally updates the tap coefficient without being influenced by a statistic quality of the noise component.

Title: Voltage/polarization state converter and light beam tester using the same
Inventor: MIYAMOTO AKINORI
IPC: G02F1/015
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To reduce the frequency dependency of the change of refractive index tensor to the interelectrode impressed voltage of an electrooptical crystal by using the electrooptical crystal where distortion is mainly caused on a plane perpendicular to an optical axis when voltage is impressed between 1st and 2nd electrodes and surrounding a part around the optical axis of the electrooptical crystal. SOLUTION: The electrodes 22 and 23 are formed on a pair of opposed surfaces of the rectangular parallelopiped electrooptical crystal 21 in this voltage/polarization state converter 20. The crystal 21 of a type that the distortion is mainly caused on the plane perpendicular to a voltage impressing direction is used and the part around the optical axis of the crystal 21 is surrounded by an enclosing body 24 having a larger elastic coefficient than the crystal 21. Therefore, the change of the distortion of the crystal 21 caused by the change of potential difference between the electrodes 22 and 23 is restrained by the enclosing body 24 and the amplitude of the resonance of the crystal 21 is decreased.  Therefore, the frequency dependency of the change of the refractive index tensor on the intensity of electric field is reduced, and the frequency characteristic of the sensitivity of a light beam tester is made flatter than the conventional one.

Abstract: PURPOSE:To realize the non-Neumann type architecture of superparallel, superdispersion, and superinformation density by stacking two kinds of organic semiconductor layers different in hand gap for one cycle in fixed stacking order into multiwell structure of superthin films. CONSTITUTION:An organic semiconductor material is made into a superthin film tens to hundreds of Angstrom  thick so as to get needed enough anisotropy, and inside the film, a one-directional superlattice is realized. The organic semiconductor materials are molecular crystals, and are stacked in the direction of the crystal axis (b-axis).

Title: Magnetic tape driving device
Inventor: SAGARA YUUJI
IPC: G11B15/70
Filed: 1979-11-28
Abstract: PURPOSE: To always keep a proper tape position with increase and decrease of the degree of tape slack, by detecting the slack of the tape and controlling the mobile reel toward the rotating direction via a control means.  
     CONSTITUTION: The detection signal sent from the tape slack detecting part 40 is shaped through the Schmitt trigger circuit 41 to be turned into the control signals of the gate circuits 42, 43. In the case of a large degree of tape slack, the pulse supplied from the pulse generating circuit 44 is supplied to the pulse driving circuit 47 through the gate circuit 42 to turn the pulse motor 49 in the direction to reduce the slack of the tape. When a proper slack of the tape is secured, the slack signal is turned off. Thus the output of the circuit 42 is also turned off to stop the rotation of the motor. Then the retrigger one-shot circuit 46 starts its operation, and the counter 45 starts after a fixed time to divide the pulse sent from the circuit 44 to then supply it to the gate circuit 43. The output of the circuit 43 turns gradually the pulse motor 49 through the driving circuit 48 in the direction to increase the tape slack. As a result, the tape can always be held in the optimum position.
