Abstract: PURPOSE:To effectively remove nonmetallic inclusion in molten metal and to form a filter having excellent spalling resistance, by coating surface of Al2O3- base porous body having large specific surface area with CaO-base refractory material. CONSTITUTION:Al2O3-base refractory raw material and binder, if necessary adding water, etc., are kneaded and formed to bar-like or string-like, dried or calcinated and burnt after filling it in the forming frame made of refractory. In this way, the porous body 7 having much spaces, light weight and high strength by intertwining irregularly with individual bar-like formed body is sintered and integrated. This porous body 7 is dipped into the calcareous emulsion and by coating with CaO-base refractory material 8 on the surface of porous body 7, to form a filter. At the time of using this filter as a weir in a tundish, Al2O3 as main component of nonmetallic inclusion in the molten steel is reacted with CaO and a kind of CaO-Al2O3 compound, such as 2CaO.7 Al2O3, etc., is formed on the surface of filter, to effectively catch the inclusion.

Title: Microphone
Inventor: MIYAJI TATSUO
IPC: H04R3/00
Filed: 1990-11-15
Abstract: PURPOSE:To easily prevent collection of undesired sound by providing a comparator means comparing the quantity of a signal level from at least two microphone elements and a variable attenuation means attenuating a signal from the microphone element varied with a control signal from a comparison means to the system. CONSTITUTION:When an X coordinate of a sound source is negative, an output level of a microphone element 1a is smaller than an output level of a microphone element 1b and a comparison means 2 generates a signal at a 0 level. Since a variable attenuation means 2 multiplies a control input AC being at a 0 level with an AS being an output of the microphone element 1a, the output of the means 2 is zero and the signal collected by the microphone element 1a does not appear at an output OS of the microphone device. Thus, when the microphone device is arranged so that the sound source whose collection is desired is located in a positive direction of the X coordinate, it is possible to effectively suppress the collection of disturbing sound from an undesired sound source located to a position whose coordinate is equivalent to a negative value.

Title: Optical temperature sensor
Inventor: KURATA NOBORU
IPC: G01K11/00
Filed: 1986-12-26
Abstract: PURPOSE:To reduce the passage loss of light and to assemble an optical temperature sensor nearly without any adjustment by aligning the optical axes of two optical fibers with each other by using a V groove and operating a movable member which moves the tip parts of the optical fibers out of the groove by using shape memory alloy. CONSTITUTION:The outer peripheries of the optical fibers 8a and 8b are plated 14 with metal partially and the fibers are fixed in the V groove 9 by soldering 15. The tip of the fiber 8a is put opposite the fiber 8b and pressed in the groove 8 by a leaf spring 13. Thus, the optical fibers 8a and 8b are made to about on each other by using the groove 9 to align their optical axes with each other. Then a coil 12 made of shape memory alloy is compressed by a coil spring 11 at room temperature to press the movable member 10 down, so light is transmitted from the fiber 8a to the fiber 8b. When the ambient temperature rises above constant temperature, the coil 12 generates a force for restoration to its original shape to press the movable member 10 up and compress the spring 11. Then the tip of the movable member 10 projects upward to press the spring 13 and fiber 8a up, so the transmission of the light between the fibers 8a and 8b is cut off.
