Title: Sound field controller
Inventor: IWAMATSU MASAYUKI
IPC: G10K15/12
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a sound field controller having a much sound field effect regardless of a simple circuit configuration by using two reflected sound generating means to generate separate reflected sound signals from an S signal and adding signals so as to set a level ratio of the generated signals to the S signal to be a specific ratio or over and reproducing the resulting signal. SOLUTION: An S signal outputted from a surround decoder 14 is given to an input difference signal adder circuit 56, in which an Lt-Rt is added to the S signal, a C signal adder circuit 64 adds a reflected sound signal of the C signal to the sum to generate a signal So. Reflected sound generating circuits 24, 26 generate separate reflected sounds r1, r2 of the signal So. A coefficient (c) is given to the reflected sound r1 at a coefficient device 28 and the result is added to the signal So at an adder 30. In this case, a level ratio c.r1/S of the reflected sound signal c.r1 to the S signal is set to be 0.5 or over for the addition. Phase change processing is applied to the reflected sound r2 by a phase shift circuit 34, and an adder 36 adds the result to the original signal So. Outputs of the adders 30, 38 are reproduced by left right speakers 32, 54 behind the listener 42.

Abstract: PROBLEM TO BE SOLVED: To make it possible to cut a metallic carrier without the formation of burrs in a gas passage by setting the focus of a laser beam to a honeycomb body consisting of oxidation resistant metallic foil having a specific sheet thickness at the surface of an object to be cut or below. SOLUTION: Plural pieces of the honeycomb carriers are produced by irradiating the honeycomb body consisting of the oxidation resistant metallic foil having <=50μm thickness. In such a case, the focus (f) of the laser beam 20 is set at the surfaces 11 of the long-sized honeycomb carrier 10 which is the material to be cut or below and the honeycomb body is cut by irradiating the body with the laser beam 20. The molten metal joins the foil materials adjacent to each other and, therefore, the welding of the end faces of the honeycomb carriers 10 after the cutting may be omitted. The laser beam output is set at >=15W per 1mm thickness of the cut honeycomb bodies.

Title: Method for recovering phosphoric acid from waste acidic solution
Inventor: YOSHIMURA KENJI
IPC: C25F7/02
Filed: 1990-09-17
Abstract: PURPOSE:To recover phosphoric acid as the aq. free acid soln. by loading a waste acidic soln. contg. salts and phosphoric acid on a strongly basic anion- exchange resin in the second operating cycle onward and using an inorg. strong acid firstly and water secondly as the developer. CONSTITUTION:A waste acidic soln. contg. salts and phosphoric acid is separated into the aq. salt soln. and aq. acidic soln. by the chromatographic separation technique using a strongly basic anion-exchange resin, and the process is repeated. In this case, the waste soln. is loaded on the anion-exchange resin at least in the second cycle onward, and an inorg. strong acid is used firstly and water secondly as the developer. As a result, the phosphoric acid in the waste soln. is recovered not as an aq. phosphate soln. but as the aq. free acid soln. Since phopshoric acid is recovered as expensive phosphoric acid in the form of the mixture with the inorg. strong acids such as hydrochloric acid, the process greatly contributes to the industrial world.

Abstract: PURPOSE:To enable the measurement of reflectance of an entire dacha mirror quickly and accurately with ease by arranging 1/4 wavelength plates each between two light emitting surfaces perpendicular to each other of a polarized beam splitter and two reflecting surfaces perpendicular to each other of a dacha mirror. CONSTITUTION:For example, when measuring the reflectance of the L-shaped surface 11L of a dacha mirror array DMA, a polarizer 104 is set at the position where the vibration surface parallels the surface of a paper and a light flux emitted from a light source 101 and made parallel by a lens system 103 turns to a linearly polarized light (P wave) with the direction of vibration parallel to the paper surface and is made incident on a polarized beam splitter 105. This linearly polarized light travels directly through the joint surface of the prism of the polarized beam splitter 105, reflected on the L-shaped surface 11L of the DMA passing through a 1/4 wavelength plate 106L and enters a detector 107 as linearly polarized light with the direction of vibration vertical to the paper surface once changed by 90 deg. in the optical path on the joint surface of the prism passing through the 1/4 wavelength 106L again.
