Title: Method for bending metallic plate
Inventor: INOUE HIROMITSU
IPC: B21D5/01
Filed: 1980-12-23
Abstract: PURPOSE: To inhibit thickening phenomena of the bottom part and to obtain bent materials which are free from press flaws and foldings, by performing bending work under such a condition where both surfaces of a discoidal metallic plate to be worked are inserted between pinching plates, respectively.  
     CONSTITUTION: Each tapered section 14a and 15a of an upper and a lower pinching plates 14 and 15 is placed opposedly to each other, and a heated discoidal material to be worked 13 is put between both the pinching plates 14 and 15 like a sandwich. Then, the sandwich is put on a lower metallic die 12, and the material to be worked 13 is formed to a bowl together with the pinching plates 14 and 15 by applying a pressure with an upper metalic die 11. When the material 13 is formed to a bowl, the marginal part of the material 13 becomes thicker than other parts, but the thickening phenomena is eliminated by the tapered sections 14a and 15a of the upper and lower pinching plates 14 and 15. When, the upper pinching plate 14 is suspended with a hanging device 15 and the outside of the lower pinching plate 15 is heated while the inside of the upper pinching plate 14 is filled with water 17, the material to be worked 13 is easily separated from the upper and lower pinching plates 14 and 15. When this method is applied, the product value of bent material is raised.

Title: Operation of audio tape in data storage device
Inventor: ROBAATO SHII RITSUCHIMONDO
IPC: G11B20/12
Filed: 1990-07-12
Abstract: PURPOSE: To discriminate between the DAT audio tape and the DAT computer data preservation tape by determining the format of the tape from which subcode information is read out and reproduced. CONSTITUTION: Whereas, in DATA DDS data tapes, the reference region begins at the point 350mm±10mm away from the beginning of the tape media(BOM), in DAT audio tapes, the beginning program region begins at the distance longer than or equal to 100mm from the BOM and, prior to the program region, a lead-in region is located. This region includes subcode information such as tape format identification information as a data ID code of the subcode block following the DAT format. Accordingly, the format information of DAT audio tapes is detected, in general, at the location closer to the BOM than the location on the DAT DDS data tape. By this, the DAT data tape and the DAT audio tape are detected and discriminated from each other.

Filed: 1993-07-26
Abstract: PURPOSE:To obtain the high use rate of gaseous ammonia and to restrain the formation of decomposition products formed by the decomposition of gaseous ammonia, such as NO2 and N2O. CONSTITUTION:When exhaust gas from a gas turbine 1 is passed through an exhaust gas duct 2 with its temperature left high and ammonia is injected from an ammonia injection device 3 in nitrogen oxide-contg. atmosphere of a high temperature of >=480 deg.C, the ammonia is reacted with the nitrogen oxide on a high temperature denitrifying catalyst 4 and made harmless to be discharged from stack 5.
