Title: Surface insulating material for molten steel
Inventor: SASAI KATSUHIRO
IPC: B22D11/111
Filed: 1992-12-02
Abstract: PURPOSE:To surely prevent the contamination of molten steel occurring in air oxidation and the reaction of the insulating material by forming the insulating material as a liquid phase in order to suppress the air oxidation and lowering the content of SiO2 in order to prevent the reaction of the insulating material and the molten steel. CONSTITUTION:The content of CaO and Al2O3 is specified to 0.5 to 1.0 in CaO/ Al2O3, the content of MgO to >=5% and 30% and the content of the SiO2 to <=10%. The reason why the content of the CaO and the Al2O3 is specified to 0.5 to 1.0 in CaO/Al2O3 lies in that the softening point of the insulating material attains the molten steel temp. <=(1550 deg.C) in a tundish and that the insulating material changes to the liquid phase. The purpose of confining the content of the SiO2 to <=10% is to suppress the reaction rate of the SiO2 and the Al in the molten steel to a level or below. As a result, the contamination of the molten steel is entirely eliminated and the quality of a slab is improved. In addition, the generation of the damage and erosion of refractories is prevented.

Title: Method of removing residual oxidant and device therefor
Inventor: MIMURA HAJIME
IPC: C02F1/28
Filed: 1993-12-24
Abstract: PURPOSE:To effectively remove a residual oxidant without leaving a gas in an active carbon bed of a fixed bed by passing a residual oxidant containing water through the active carbon vessel having a fixed bed of the active carbon as the under bed and a fluid bed of the active carbon as the upper bed. CONSTITUTION:A residual oxidant removing device for removing a residual oxidant generated at the time of sterilizing sea water used for breeding and cultivating marine products by allowing to contact with ozone is provided with the active carbon vessel 13 having the fixed bed 11 of the active carbon as the under bed and the fluid bed 12 as the upper bed. And the residual oxidant is removed by the active carbon in the fixed bed 11 and the fluid bed 12 by feeding the residual oxidant containing water into the fixed bed 11 side of the active carbon vessel 13 through a feeding pipe 14 and discharging from the fluid bed 12 side through a discharging pipe 15. In this case, gas enables to easily go through by controlling the particle diameter of the active carbon in the fixed bed to large size of >0.5mm and making the shape spherical and the treatment efficiency is increased by reducing the thickness of the fixed bed 11.

Title: Radio transmitter
Inventor: KUMAGAI YUKIHIKO
IPC: H03C5/00
Filed: 1993-12-24
Abstract: PURPOSE:To suppress the amplitude components generated in the FM orthogonal modulation by providing a switch circuit, reducing attenuation of an attenuator at the time of the FM modulation and lowering the amplification factor of a frequency converter. CONSTITUTION:A switch circuit 9 reduces the attenuation of an attenuator 5 with the voltage 11 from the circuit 9, and limits the amplitude of the input to a frequency converter 6 from an orthogonal modulator 3 so that the converter 6 may operate in a saturation area. A switch circuit 10 reduces the bias current to the converter 6 with the voltage 11 from the circuit 10, lowers and adjusts the amplification factor so that it may be the same as the output of the converter 6 before a switching, and limits the amplitude by lowering the amplification factor. Therefore, when this transmitter operates as an FM modulator, the amplitude is limited by both input/output of the converter 6 by operating the switch circuits 9 and 10, and unnecessary amplitude components in the orthogonal modulator 3 is reduced.

Title: Electrophotographic photoreceptor
Inventor: INOUE TOMOHIRO
IPC: G03G5/05
Filed: 1993-12-22
Abstract: PURPOSE:To obtain a photosensitive body having high sensitivity in which decrease in the electrifying property or increase in the residual potential are not caused even repeatedly used by dispersing an azo pigment individually in two or more kinds of solvents having different solubility parameters and then mixing them to use a charge producing agent for a charge producing layer. CONSTITUTION:A charge producing layer 2 and a charge transfer layer 3 are successively formed on a conductive base body 1. An azo pigment is disperhed separately in two or more kinds of solvents having different solubility parameters and then mixing them to obtain the charge producing agent to be used for the charge producing layer 2. When the azo pigment is dispersed, the state of dispersed particles differs depending on the dispersion solubility parameters. This is because wettability of the azo pigment differs depending on the dispersion solvents, and thereby, stability or the like of pulverized primary particles differs. This state of particles largely influences the electrostatic property. Thereby, by mixing two or more kinds of dispersion particles as the charge producing material, the effect on electrostatic characteristics can be improved.

Title: Vortex flowmeter
Inventor: KASHIMOTO HIROO
IPC: G01F15/08
Filed: 1993-12-27
Abstract: PURPOSE:To prevent a liquid from being left in a measuring path within a vortex-generating body in an ultrasonic vortex flowmeter for gas. CONSTITUTION:A vortex-generating body 14 having a measuring path 15 is formed in a housing 13 of a main body. A flow path 13a is communicated with the measuring path 15 via an introduction port 16. Ultrasonic transceivers 18, 19 are set at both ends of the measuring path 15, which is mounted to the housing 13 via O rings 20 and packings 21. Drain holes 22, 23 are formed in the vortex-generating body 14. When a gas runs in the flow path 13a thereby to generate a Karman vortex downstream of the vortex-generating body 14, a flow is generated within the measuring path 15 with the same cycle. The modulation of ultrasonic signals between the ultrasonic transceivers 18 and 19 because of the flow is demodulated by an amplifier circuit 24, whereby a flow rate of the gas is operated. Even when drops of dew are formed inside the measuring path 15 as a result of a sudden temperature change, the fluid is discharged from the drain holes 22, 23 to the flow path 13a, thereby preventing the ultrasonic waves from being propagated through the liquid in gaps C1, C2 between the ultrasonic transceivers 18, 19 and the housing 13.

Title: Manufacture of compound semiconductor element
Inventor: TSUJI MASAYOSHI
IPC: H01S5/227
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To simplify the manufacturing process by oxidizing a part of compound semiconductor layer and performing growth selectively, using the oxidized compound semiconductor layer as a mask. SOLUTION: When a selective growth layer is formed in the gap of a mask, an oxidized compound semiconductor mask is employed in place of an SiO2 mask. For example, an n-AlGaAs clad layer 2, an n-GaInP oxidation stop layer 3 and an AlGaAs layer 4 are laminated sequentially on a GaAs (100) substrate 1. The AlGaAs layer 4 is patterned into a pair of stripe mask and oxidized. The oxidized AlGaAs layer 5 is employed as a mask for selective growth and a double heterostructure is grown selectively. Since the oxidized AlGaAs layer 5 is employed as a mask for selective growth, formation of an SiO2 mask is not required, and the deposition process of SiO2 can be eliminated resulting in a simplified manufacturing method.

Title: Multiple-wavelength type radiation thermometer
Inventor: MARUI TOMOTAKA
IPC: G01J5/00
Filed: 1991-12-10
Abstract: PURPOSE:To make it possible to measure the accurate temperature of a surface even if the thickness of an oxide film, which is formed on the surface to be measure, is changed in time and the emissivity of the measured wavelength is changed. CONSTITUTION:Four different wavelengths lambda1-lambda4 of the lights from an object to be measured are received with a light receiving part 10, and luminance temperatures S1-S4 corresponding to the wavelengths are inputted into an operating block 12. The ratio of the power of the emissivities is computed for the combinations of (S1, S2), (S2, S3) and (S3, S4). Points (X, Y and Z) on the closest regression function F from the actually measured point on a three-dimensional space determined by the ratio of the power of three emissivities are judged. A mapping H is applied on the points on the function F. The points are converted into the points (x, y and z) on the three- dimensional regression function G of the ration of the emissivities based on the mapping H (d). Of the ratio of the power of the emissivities obtained with the operating block, the ratio having the small time change is selected. The emissivity ratio corresponding to the ratio of the power of the emissivity is selected from x, y and z. The surface temperature Y is computed with a temperature computing block 22, and the temperature is outputted.
