Title: Echo elimination method and echo elimination device
Inventor: SUGIYAMA AKIHIKO
IPC: H04B3/23
Filed: 1992-02-19
Abstract: PURPOSE:To obtain the echo elimination method and the echo elimination device with a short converging time in which no double talk is detected. CONSTITUTION:An adaptive filter 3 generates a replica of an echo leaked by a microphone 1 by using a reference signal fed via an input terminal 7 and eliminates the echo by subtracting the replica from the echo at a subtractor 4. A gradient of an error between the echo and the echo replica with respect to a coefficient of the adaptive filter 3 is successively calculated at a step size controller 6 by using a difference signal being an output of the subtractor 4, and the coefficient of the adaptive filter is updated by using the result of calculation. When a control circuit 8 detects it that an instantaneous power of a near end signal is remarkably larger than an instantaneous power of the echo, a selector 9 selects '0' in place of the step size from the step size controller 6 and sends the result to the adaptive filter 3 to stop the revision of the coefficient.

An inert gas is fed from a gas introducing pipe 6 and ionized by a shower of ions from an electron emitting source 4. High voltage is then applied to an acceleration electrode 8 to implant the ionized inert gas, so the vapor-deposited metallic film is implanted into the substrate 9 to ensure adhesive power. Finally, a film is formed to the desired thickness by a cluster ion beam vapor-deposition method.

Title: Ink jet recorder
Inventor: MOCHIZUKI SEIJI
IPC: B41J2/125
Filed: 1990-03-20
Abstract: PURPOSE:To prevent preliminarily an inconvenience to be caused by running out of ink by a method wherein that variation in resistance to be generated between an electrode coming in contact with a porous material in an ink tank and an electrode in an ink chamber is detected to exceed respectively two established values. CONSTITUTION:When gas having entered foam 7 reaches an upper opening end of an ink chamber 12 and an area of a connection part of ink for connecting the foam 7 to the ink chamber 12 starts decreasing, variation in resistance is immediately detected as a variation with a differentiating circuit 16. When the variation comes to exceed a set value A of a comparator 17, the variation being in a near end state is displayed. A state of running out of ink between the ink in the foam 7 and the ink in the ink chamber 12 comes before long. When the variation of variation in resistance comes to exceed a set value B of the comparator 17, printing operation stops immediately at a point of time when a carriage 2 returns to a home position by an output signal from the comparator 17. Since the ink remains in the ink chamber at the point of time, air can be certainly prevented from entering a pipeline to a nozzle.

Title: Radiation detector
Inventor: HOSHI JIYUNICHI
IPC: G01T7/00
Filed: 1979-06-05
Abstract: PURPOSE: To eliminate the contamination for the detection and thus ensure the accurate measurement at all times, by providing the air layer in front of the plastic scintillator to exhaust the contaminated air.  
     CONSTITUTION: The clean air is led in from outside via pump 9 and ventilation tube 10 each, and thus clean air layer 11 is formed between the front of plastic scintillator 4 and incident window film 8. As a result, the greater part of the radioactive gas can be exhausted outside via the clean air although part of the radioactive gas within measurement container 2 may transmits through film 8. Accordingly, almost no radioactive gas enters directly scintillator 4 to give contamination there, and thus the detection error can be reduced. The film through which the radiation of plastics, beryllium or the like can pass easily is used for film 8. At the same time, the effect of heat exchange is obtained by exhausting the air via the pump. As a result, the sudden change of the temperature can be avoided for the detector main body, thus keeping the detector main body at a constant temperature.
