Title: Echo canceller device
Inventor: ITO HIDENORI
IPC: H04B3/23
Filed: 1990-11-20
Abstract: PURPOSE:To sufficiently cancel the echo without degrading the quality of speech by changing the clipping level of a nonlinear circuit in proportion to an integral value as the output of an integrating circuit constituting a canceller device to change the clipping level in accordance with the magnitude of echo. CONSTITUTION:The other-party speech signal from a reception-side signal line 1 is inputted to an echo canceller device 9, and the output of this device is sent to an echo line 3 and an false echo line 14. The reception signal sent to the echo line 3 is inputted to the device as an echo signal, and the signal inputted to the false echo line 14 having the same characteristic as the echo line 3 is outputted from the false echo line 14 as a false echo signal approximating the echo signal. This false echo signal is inputted to a nonlinear circuit 16 as a DC signal proportional to the magnitude of the signal by an integrating circuit 17 to control the clipping level. Meanwhile, the false signal is subtracted from the echo signal inputted to an echo canceller circuit 13 to eliminate the echo left unerased.

Title: Fusion splicing method for optical fiber
Inventor: TAYA HIROYUKI
IPC: G02B6/255
Filed: 1990-11-20
Abstract: PURPOSE:To shorten the time required for fusion shaping and to improve splicing efficiency by making a discharge current at a shaping stage higher than the discharge current at a preliminary heating stage and a pressing stage. CONSTITUTION:The discharge current at the preliminary heating stage and the pressing stage in the fusion splicing method of an optical fiber is set as in the conventional manner, and the discharge current at the shaping stage which is successively performed is set larger than the above discharge current and the time for aligning axes by a self aligning action at the shaping stage is shortened, so that the fusion splicing time of the optical fiber is shortened. Since the discharge current at the shaping stage is made higher, a heating temperature is made high and the speed of the self aligning action of the optical fiber is made high. Thus, not only the time for aligning the axes but also the fusing splicing time are shortened, thereby improving the splicing efficiency.

Title: Method and device for drawing liquid from centrifugal separator
Inventor: OTSUTOO BIYUTSUTONAA
IPC: B04B11/08
Filed: 1990-11-20
Abstract: PURPOSE: To optimize a leading-out process for liquid by adjusting the leading- out process by a sensor for monitoring the packing height and/or surface characteristic of the packing material in a centrifuge drum. CONSTITUTION: The packing height and/or surface characteristic of the packing material in the centrifuge is monitored by using the sensor 60 at the time of withdrawing the liquid 40 from the centrifuge by advancing a leading-out pipe 50 into the liquid 40 layer to be led out. When the change of the packing height with lapse of time turns to O and/or when the sensor 60 detects the shift from the liquid to solid surface characteristic, the withdrawing process is ended. Consequently, the leading-out process for the liquid may be optimized.

IPC: F16H55/36
Filed: 1986-12-26
Abstract: PURPOSE:To aim at miniaturization of a pulley with internal gear, reduction of noises produced by the engagement between the internal gear and a pinion, improvement of the accuracy in forming the internal gear and improvement of the productivity of a pulley with internal gear by forming a resin internal gear so that it locks onto the inner peripheral surface of a metallic pulley. CONSTITUTION:In a pulley with internal gear, a resin internal gear 6 is locked onto a fixing means 5a, which is provided on the inner periphery part of a metallic pulley 5 formed into a one-sidedly bottomed cylindrical shape, through fabrication from an opening edge. Accordingly, when the driving force of a prime mover or an electric motor is transmitted by means of a belt to the metallic pulley 5 and the metallic pulley 5 is caused to rotate, the resin internal gear 6 locked onto the inner peripheral part of the metallic pulley 5 drives a pinion and transmits the rotating power. Since a resin material is generally lighter in weight and has a smaller modulus of elasticity as compared with a metallic material, miniaturization of a pulley with internal gear, and reduction of noises produced by the engagement between a pinion and the internal gear 6 can be obtained.

Filed: 1988-12-12
Abstract: PURPOSE:To decrease the power consumption of a battery by braking a rotor by rotation of permanent magnet supporting frames or a switching board supporting frame to change the state of overlap of permanent magnets and switching boards. CONSTITUTION:When permanent magnet supporting frames 6-1 to 6-3 or a switching board supporting frame 2 is rotated, with permanent magnets 4, 5-1, and 5-2 and switching boards 3-1 and 3-2 overlapping one another to place said permanent magnets 4, 5-1, and 5-2 across said adjacent switching boards 3-1 and 3-2 and overlap said magnets on half of each of said switching boards on both sides, a magnetic circuit is formed between the adjacent permanent magnets 4, 5-1, and 5-2, one of the switching boards 3-1, and one of the switching boards 3-2 on both sides. Therefore, no eddy current flows and no braking torque is generated because magnetic flux generated from the permanent magnets 4, 5-1, and 5-2 does not act on the surface of a disc. Thereby the power consumption of a battery can be decreased.
