IPC: C22B1/16
Filed: 1984-11-07
Abstract: PURPOSE:To improve the strength and yield of a formed part, and also to prevent a time aging deterioration of the strength by adding an iron oxide contained raw material of a proper quantity to a CaO-SiO2 compound fluxing agent, adding a chrome ore and a powder coke to said agent, mixing, pelletizing and sintering them. CONSTITUTION:An iron oxide contained raw material is added to a CaO-SiO2 compound or CaO-SiO2-MgO compound fluxing agent consisting of lime stone, quartz sand, serpentine, etc., so that a ratio Fe/Ca of Fe and Ca becomes >=0.10, and mixed and pelletized in advance by a drum mixer. Subsequently, a chrome ore and a powder coke are added to the pelletized matter, and mixed and pelletized by the drum mixer. As for said chrome ore, it is desirable that a total quantity of CaO and SiO2 or a total quantity of CaO, SiO2 and MgO is set to about 35wt% against the chrome ore. By sintering said pelletized matter by a sintering machine, an unmolten part of the fluxing agent is eliminat ed completely, and a chrome sintered ore formed part which has a high strength and also whose strength is not effected by time aging deterioration is obtained with a high yield.

Abstract: PROBLEM TO BE SOLVED: To enable simple and efficient welding at uniform strength without using flux even if melting points of a welding object and an object to be welded differ by forming a plane part and forming a hole in the plane part for pulse welding. SOLUTION: A hole 12 is formed by burring machining from the inside of a case 11 toward the outside thereof in the case 11. At this time, an annular rib 13 is formed in a peripheral side part of the hole 12. A peripheral part 15 on an inner side of the case 11 of the rib 13 has a predetermined curvature. An electrode face set to the same curvature as that of the peripheral part 15 on the inner side of the case 11 of the hole 12 is formed in an electrode on one side for pulse welding, and this electrode is inserted into the hole 12. At this time, since the peripheral part 15 of the hole 12 and the electrode face come in face-contact mutually, it is possible to reduce contact resistance of the electrode and the case 11 and provide uniform resistance distribution.

Title: Short-circuit detector
Inventor: SHIMIZU TOSHIFUMI
IPC: G11B5/09
Filed: 1992-09-03
Abstract: PURPOSE:To select the input frequency irrespective of the LH value of the load by detecting the state of the load from the difference of the input level of a comparison circuit. CONSTITUTION:When input terminals 7, 3 are H, NPN transistors(Tr) Q2, Q3 are turned ON to pass ICQ2, ICQ3. The current waveform shifts to the negative side. Thereafter, the terminals 2, 8 become H, and TrQ1, TrQ4 are turned ON to feed ICQ1, ICQ4. Accordingly, the current waveform shifts to the positive side. If a load short-circuits, the terminals 3, 7 are turned to H and the TrQ2, TrQ3 are turned ON, with allowing ICQ2, ICQ3 to flow. As a result, the current waveform shifts to the negative side. Subsequently, when the terminals 2, 8 are changed to H and the TrQ1, TrQ4 are turned ON, ICQ1, ICQ4 are supplied, whereby the current waveform is shifted to the positive side, and OUTX and OUTY indicate a short circuit. The difference of OUTX and OUTY becomes the same at the write time of the X side and the write time of the Y side. Therefore, it is possible to select the input frequency of a signal impressed to the input terminal irrespective of the LH value of the load in a comparison circuit having the output inverted by 0.1V input difference.
