Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To easily provide reproduced sounds desirable for a listener even when a listening position or the like is changed. SOLUTION: A test signal oscillator 8 generates a test signal having flat frequency characteristics. The test signals are discharged from a speaker 20 and collected by a microphone 9 arranged at the listening position. The frequency characteristics of collected test signals are detected by a frequency analyzer circuit 12. Corresponding to the detected frequency characteristics of the test signals collected at the listening position, a coefficient calculating circuit 13 finds a parameter for applying characteristics inverse to these frequency characteristics to a filter circuit 3 and sets that parameter to the filter circuit 3. The frequency characteristics are controlled by the filter circuit 3 and the reproduced sounds, for which the frequency characteristics are made flat at the listening positron, are outputted.

IPC: G11B27/10
Filed: 1984-03-13
Abstract: PURPOSE:To positin accurately a tape at a prescribed point by deciding the inertia of tape while the tape is wound and then stopping the tape at a precribed point after the tape inertia is decided. CONSTITUTION:A CPU28 supplies a control signal to a magnetic recording/reproducing device 10 to start a take-up action of a magnetic tape 12. The inertia of the tape 12 is calculated at a brake point and used to decide an accurate point when the device 10 is set under a pause mode. Then the tape 12 is positioned at a target. When the tape 12 is wound from one side to the other side, the tape is shifted to a take-up reel 16 from a supply reel 14. Therefore the brake pint is selected so as to get close to the target, and as a result the tape inertia is continuously changed as the tape is wound round the reel 16. The CPU28 produces a control signal after the inertia of the tape 12 is calculated at the brake point. As a result, the device 10 increases the speed of the tape 12 up to the prescribed maximum value VMAX.

Abstract: PROBLEM TO BE SOLVED: To accelerate the production of weather-resistant stale rust without damaging the appearance on the surface of a steel material by forming a coating film of specified thickness containing one or more kinds of compds. of Cu, Ni, Cr, Al, Mo and P, an org. resin, a photosensitizer, pigments and a coating controlling agent on the surface of the steel material. SOLUTION: A treatment film containing at least one kind selected from compds. of Cu, Ni, Cr, Al, Mo or P by 0.03 to 15% calculated as metals, an org. resin, a photosensizer, pigments and a coating controlling agent is formed to 1 to 100 μm film thickness on the surface of a steel material. The org. resin in the treatment film is preferably a resin having chelate forming groups in order to fix and concentrate ions eluted from steel to form a uniform stable rust layer on the interface. By the presence of the photosensitizer, the photodecompositon of the resin in the coating film is accelerated the film is uniformly deteriorated and therefore, this prevents the coating cracks which inhibit uniform formation of a stable rust. The coating film can be formed by air spraying, airless spraying, brush coating or the like and heating or baking is not necessary.
