Title: Stereo noise reducing circuit
Inventor: NUMATA TATSUO
IPC: H04B1/16
Filed: 1982-10-06
Abstract: PURPOSE:To vary the mixing degree in response to the difference signal level between L and R signals and to reduce noise to prevent the deterioration of separation, by providing a subtractor, a waiting circuit, an envelope detector, etc. to a noise filter connected to an FM receiver. CONSTITUTION:A filter B is connected to an FM stereo receiver A, and a subtractor 12 is provided to the filter B to deliver the difference signal between L and R channel signal from the receiver A. This difference signal is applied to a waiting circuit 13, and this signal 13 increases the frequency level which is audible to human ears. The L and R signals delivered from the circuit 13 are fed to an envelope detecting circuit 14 to deliver the DC voltage corresponding to the levels of L and R signals. This DC voltage controls the resistance value of a voltage variable element 18, and the output of the element 18 controls a switch 9 which supplies the output of a level detector 7. Then the mixing degree is increased when the difference signal is small to reduce noises. This prevents the deterioration of separation.

Title: Control method for optical amplifying medium, optical amplifying device, and system using it
Inventor: KOSAKA JUNYA
IPC: H04B10/29
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To improve control response, suppress the occurrence of optical surge and amplify signal light input without degrading the signal-to-noise ratio of optical output by returning branch light from an optical amplifying medium to the optical amplifying medium inversely with optical output. SOLUTION: Optical output Pout, composed mainly of signal light, of an optical amplifying device is obtained as 81% of the entire optical output Pout'. Therefore, a 980-nm exciting light source 23 and an adjusting means 28 are controlled by a controlling means 7 based on the detected optical power from an optical detecting means 6. In an erbium-added optical fiber 22, the exciting light from the 980-nm exciting light source 23 acts to increase gain, and the return light from a returning means 4 acts to reduce gain. Therefore, the required optical power of return light can be adjusted as desired only by increasing and reducing the exciting light from the exciting light source. This makes it possible to improve control responsibility, suppress the occurrence of optical surge and amplify signal light input without degrading the signal-to-noise ratio of optical output.

Title: Lithography and device thereof
Inventor: SUGA OSAMU
IPC: H01L21/027
Filed: 1988-07-18
Abstract: PURPOSE:To prevent heat generation due to the continuation of shots by obviating the spatial adjoining of shots continuing with time in each molding electron- ray shot executed by a variable molding type electron-ray lithographic device. CONSTITUTION:An electron beam 12 emitted from electron rays 11 is deflected by a beam deflection system 13, and shot onto the surface of a sample 15 on a movable sample base 14, and a desired graphic is drawn and processed while the shots are connected successively. Each shot continuing with time is not made to adjoin spatially at that time. Consequently, shots to the sample 15 are not continued spatially, thus preventing the heat generation of the sample 15 due to the continuation of the shots. Accordingly, a fine drawing pattern can be formed without increasing the drawing time.
