IPC: H01F27/25
Filed: 1978-10-13
Abstract: PURPOSE: To improve material utilization rate and also to minimize iron loss, by winding a low-grade directional silicon steel sheet on center section in layer-piling direction and also winding a high-grade directional silicon steel sheet on inner and outer circumferential sections.  
     CONSTITUTION: A coiled steel core 1 is divided into 3 sections in layer-piling direction, a relatively low-grade directional silicon steel sheet is used in a center section 5 and a relatively high-grade directional silicon steel sheet is used on the both sides 4 and 6 of the center section so that the ratio of the latter to an entire body becomes 5W30% in weight percentage. By doing this, magnetic flux density distribution in the layer-piling direction of the coiled steel core 1 can be equalized, the iron core's characteristics can be remarkably improved simply by adding a small amount of a high-grade directional silicon steel sheet to a low-grade directional silicon steel sheet, and therefore, reduction of iron loss can be achieved economically.

Abstract: PURPOSE:To effectively remove foreign matters such as flash from a trimming die for die cast products, and to prevent generation of troubles of dies and the defective quality of the products. CONSTITUTION:A trimming die (projecting die) 1 is divided into two parts, i.e., a die surface member 1a and a die table member 1b, and a passage 5 is formed in the mating surface part between the die surface member 1a and the die table member 1b, and at the same time, an air introducing port 6 to introduce the compressed air from an outer air blow into the passage 5 and a plurality of blow-out ports 7 to blow out the air from the passage against the die surface are formed therein. Similarly, a recessed die is also divided into two parts, and a passage, an air introducing port and a blow-out port are formed therein. The blow-out ports of both dies are arranged with the axes being deviated from each other. After trimming, the turbulence flow is generated between the dies by blowing out the compressed air introduced into each passage from the blow-out ports, and foregin matters such as flash are scatteringly removed thereby.

Filed: 1980-09-11
Abstract: PURPOSE:To give an interlock information without transferring unnecessary information, by changing the interlock information to a serial signal, and also giving a constant rule for an information transfer to the controller to which said signal has been connected in a loop. CONSTITUTION:Serial interface cards 461-463 are constituted in a loop, and from each card, the information is sent out by adding its own interlock information, and also the interlock information of other necessary card is inputted to a processor of a microsequencer related to itself, through a bus. A timing signal in this case performs its duty by the fact that a shift signal and a write strobe signal flow in a loop. According to this constitution, unnecessary information which is left by shift in 1 cycle matters little, and also the wiring work cost is reduced.

Filed: 1985-06-10
Abstract: PURPOSE:To effectively remove resin burrs without deforming leads by pressing downward tops of projections of resin burrs by a roller or a flat mold to remove the burrs from cavities, and then removing the remaining burrs by a blaster. CONSTITUTION:After a transfer molding is finished, the projections 13 of resin burrs 6 are disposed upward, and a resin molded portion 7 is secured by a retainer jig 14 while a tie bar 9 remains mounted. The tops of the projections 13 of the burrs 6 are pressed down by one roller 15, and the burrs 6 are removed from cavities 11, 12 and from the upper surfaces of leads 8. In this case, since a cut portion 10 is formed, the width of the roller 15 may be sufficiently increased, and the transfer molding can be facilitated. Then, if the removal of the burrs 6 is insufficient, the remaining burrs 6 are completely removed by a blaster. When the roller 15 is thus used, the burrs 16 may be removed without contacting the leads 8.

Abstract: PROBLEM TO BE SOLVED: To make it possible to restore occlusal force and beauty by implantation of an artificial tooth right after the extraction of the tooth without waiting for a restoration period by templating at least part of the dental root of the extracted tooth and manufacturing the artificial dental root. SOLUTION: A resin E, such as epoxy resin, is first put into a vessel and the extracted tooth T which is cut at its top and bottom and is subjected to a surface treatment is embedded as the male mold of the upper part of the artificial dental root into this resin. This tooth is removed after waiting for curing of the resin. The cavity formed after removal of the extracted tooth T has the same shape as the shape of the extracted tooth T. Next, a metallic cylinder C is previously aligned and placed in the safe and desirable direction where the bone quantity is the largest. An approximately cylindrical guide 10 is formed on the circumference of the cylinder C when an instant-set curing material, such as a cold-curing resin, is built up on the circumference and is cured.  In succession, the metallic cylinder C is removed and the cavity bottom is bored with a hole of a depth of 5 to 6mm with the guide 10 as a guide. The guide 10 is thereafter removed and a plastic pattern 8 is inserted into the bored hole and wax W is packed in the upper part, into which a plastic pattern 9 is embedded.
