Title: Ac electromagnet
Inventor: UCHIDA KAZUMI
IPC: H01F7/10
Filed: 1986-06-06
Abstract: PURPOSE:To prevent the mechanism life from being affected by the alternating magnetic flux caused by an exciting coil by integrally molding the fixed core and the moving core with a cast resin except for the contact surface. CONSTITUTION:A core plate is formed in the shape of an 'E'-letter, as well as intetrally molded with a cast resin 8 except for the contant surface 7a of the core plate. As the cast resin, a thermoelastic resin such as polyamide or a thermosetting resin such as eposy resin is used. As in the integral molding wherein a rivet is used, the rivet is heated by an alternating magnetic flux passing through a one-turn coil which the rivet constitutes, so reduction of the mechanical strength due to reduction in strength or elongatiion in length of the rivet itself would not be provided. Further, since a light-gage silicon steel plate is used as the core plate and the temperature rise of the silicon plate itself is small, the temperature rise of the cast resin is also small, so reduction of the integration strength due to the change in hardness or elongation of the cast resin can substatially be ignored, whereby a core for an ac electromagnet having a long mechanical life is obtained.

Title: Production of glass fiber strand
Inventor: KATAYAMA MASAAKI
IPC: C03B37/022
Filed: 1978-10-27
Abstract: PURPOSE: To obtain a glass fiber strand with no flaw and no unevenness in adhesion of greige goods by bundling glass fibers during passing them into a V-form groove cut in a bundling member made of phenol resin.  
     CONSTITUTION: In production of a glass fiber strand by drawing out many glass fibers and bundling them with greige goods, the fibers are passed into a V-form groove cut in a bundling member made of phenol resin, and during this time the fibers are bundled. Since the wall of the bakelite member is roundish, the resulting fiber strand is considered not to be flawed even if it slides rapidly on the member. The reason why the strand undergoes little unevenness in adhesion of the goods is considered as follows: the bakelite member has few surface micropores, so the goods is prevented from sticking, depositing and becoming small blocks by anchoring effect due to penetration of the goods into the micropores.

Title: Preventing method of water drop formation in mold when tundish in horizontal continuous casting apparatus is preheated
Inventor: KOMORI HIDETOSHI
IPC: B22D11/10
Filed: 1979-10-12
Abstract: PURPOSE:To prevent the formation of water drops in mold caused by exhaust gas, by shifting relative positions of the nozzle and the mold while the tundish is being preheated. CONSTITUTION:The preheating of the tundish 1 is started after the mold 3 (containing the water cooling equipment 4) is moved laternally by operating the laternally shift device 5 and the relative positions of the mold 3 and the nozzle 1 are shifted not to meet each other. While the tundish 1 is being preheated, exhausted gas generated there is vented out of the tundish 1 passing through the nozzle 2. As the mold, though it is being ready to operate, is located not to meet the tundish 1, the exhaust gas from the tundish can not flow into the mold 3 and water drops would never be generated on inner surface of the mold 3. After preheating work is over, the mold 3 is moved back by the laterally shift device 5 to the original position meeting the nozzle 2 and then fixed there. Thus, the casting operation of molten steel can be started and continued safely with without anxiety of explosion.

Abstract: PURPOSE:To improve measuring accuracy, by immersing a pair of electrode comprising lead and lead dioxide in the electrolyte of a battery, immersing another pair into sulfuric acid having a constant specific gravity filled in a container, which is immersed in the electrolyte, and connecting both electrode systems so as to offset the potential differences each other out. CONSTITUTION:An electrolyte 2 comprising dilute sulfuric acid is sealed in a battery jar 1. In the electrolyte 2, a plate group 5 comprising positive plates, negative plates, and separaters, is immersed. A reference electrode part 9 comprises a pair of a lead electrode and a lead dioxide electrode. The electrodes are constituted of the same electrodes as those in a specific-gravity detecting electrode part 6. The electrode part 9 is immersed into a container 11, which is filled with sulfuric acid 10 having a constant specific gravity, and immersed in the sulfuric acid 10. The container 11 is immersed in the electrolyte 2, and the electrode part 6 is also immersed in the electrolyte 2. The electrode parts 6 and 9 are connected in the direction where the potential differences are offset. A potentiometer 7 is connected to the electrode parts 6 and 9 so as to display the offset potential difference. Thus the sensitivity of the measuring instrument is increased and the change in potential difference due to temperature change in electrolyte is compensated. Therefore highly accurate measurement of the specific gravity can be performed.
