IPC: H04B1/38
Filed: 1994-02-28
Abstract: PURPOSE:To prevent deformation of an antenna element and to prevent the change of a characteristic frequency by providing an exterior body so as to hold the antenna element. CONSTITUTION:The antenna element 6 is formed by working a wire body provided with conductivity such as stainless wire, copper wire and iron wire, etc., to a helical shape.

Abstract: PURPOSE:To provide a smelting reduction method of a metal oxide, by which the wear of a furnace refractory is restrained and the service life of the furnace refractory can be prolonged. CONSTITUTION:Magnesia-containing material is added to slag and the temp. of molten iron is raised and also, the magnesia content in the slag is made higher than the saturated solubility by 1-20%, i.e., the solid magnesia-containing material is in existence in the slag through temp.raising and slag-making period for executing the slag-making at the initial stage, and smelting reductio period for charging and reducing the metal oxide. At the time of keeping the magnesia content in the slag within the super saturation range, elution of the magnesia from the furnace refractory is restrained and the erosion of the furnace refractory caused by the elution of the magnesia is greatly reduced. Further, in the temp. raising and slag-making period, since a quickly meltable material such as magnesia clinker is added as the magnesia source, the magnesia content can be kept in the saturated condition even in the temp.raising and slag-making period, and the wear of the furnace refractory is further reduced.

Title: Detection system for program runaway
Inventor: TASHIRO SHIYOUJI
IPC: G06F9/42
Filed: 1983-02-24
Abstract: PURPOSE:To prevent a runaway of a program by executing an instruction CALL at an optional check point and writing addresses which are programmed so that a jump to an error processing routine is made in a return destination stack. CONSTITUTION:A program to be executed at some check point has the statement CALL for calling a main program 9 in an address I and the error processing routine following an address (I+1). When the statement CALL in the program P8 is executed at some check point, a return address (I+1) is stored in an address ''00'' of the return destination stack indicated by a counter, which is increased by one to indicate ''01''. For example, the execution moves to an address K of a subroutine program P10 from an address J of a program P9. Then when an instruction RET is executed, the contents of the counter is decreased by one and the return address (I+1) in the address ''00'' of the return address stack is fetched. Consequently, the error processing routine after the address (I+1) is executed to stop the execution of the program.

Title: Cutting apparatus for semiconductor wafer
Inventor: KAI MITSUKUNI
IPC: H01L21/301
Filed: 1980-03-11
Abstract: PURPOSE:To prevent chips from being adsorbed onto a metal electrode of the wafer by constructing a water fixing surface of a die stage of an insulating material 12 while a cooling substance is jetted onto a cutting section of a cutting edge turning. CONSTITUTION:A tape made of an insulating material 12 is fixed on the surface of a die stage 10. Water, for instance, is jetted onto a section where a fast rotating cutting blade 14 cuts a wafer 11 and a surface active agent 18a is dropped from above the stage 10 thereby preventing a cut layer from being adsorbed onto the surface of the wafer. This separates the wafer 11 from the stage 10 electrically thereby preventing the movement of electrostatic charges generated with the rotation of the blade 14 and those of a thermal battery caused at the joint of an element on the wafer. Easy cutting of the wafers to a given shape can improve the yield.

Filed: 1983-02-25
Abstract: PURPOSE:To provide an air conditioning system in which heat loss is small by effectively utilizing heat by transferring heat within an air-conditioned chamber to other chamber in utilization of a heat pump cycle. CONSTITUTION:A first heat exchanger 1 and a second heat exchanger 8 are provided respectively in separate rooms, and a compressor 7 and a strangulation resisting part 9 are connected to the above described first and second heat exchangers 1 and 8 to thereby form a heat pump cycle. By operating a cooling and heating apparatus 13, one room 4a is heated and other room 4 is left to be cold. In a case where the room 4a is not used for sleeping but the room 4 is used therefor, a four way valve 6 is switched as shown by broken lines in the drawing to cause a heat medium to flow. Then, the first heat exchanger 1 acts as a condenser and the second heat exchanger 8 as an evaporator, and hence heat within the room 4a moves to the side of the room 4. Thus, the room 4 is heated and the room 4a is cooled. Hence, heat heated by the cooling and heating apparatus 13 can be effectively transferred.
