Title: Electronic time delay detonator
Inventor: KUSAKA YASUHIRO
IPC: F42B3/16
Filed: 1990-05-11
Abstract: PURPOSE:To prevent the generation of spilling of a diazonitrophenol initial explosive of the electronic time delay detonator and to completely eliminate the phenomenon that the initial explosive fails to make normal initial explosion by maintaining the apparent density of the initial explosive at a specific value. CONSTITUTION:The apparent density of the initial explosive 4 of the electronic time delay detonator by press packing the initial explosive 4 consisting of diazonitrophenol or a mixture composed of diazonitrophenol and potassium chlorate, etc., is specified to 1.00 to 1.16g/cc in an inside pipe 6. The jumping of the initial explosive 4 out of the inside pipe 6 when subjected to a fore-stage impact is prevented in this way. The spilling of the initial explosive 4 arises when the initial explosive is subjected to the impact if the apparent density of the initial explosive 4 is below 1.00g/cc and a so-called dead pressure is generated when the apparent density exceeds 1.16g/cc.

Title: Automatic gain control system in digital transmission

Filed: 1980-09-03
Abstract: PURPOSE:To adopt the AGC system in the signal transmission from a DC up to an optional transmission speed, by setting the ration of outputs of logical ''1'' and logical ''0'' to a constant to output them from a transmitter. CONSTITUTION:When the signal inputted to an input terminal 11 is logical ''1'', a discriminator 13 turns off a switch circuit 15, and the input signal to the discriminating circuit 13 is attenuated to 1/K through an attenuator 14 and is fed back to a control circuit 16. Meanwhile, when the signal inputted to the input terminal 11 is logical ''0'', the discriminator 13 turns on the switch circuit 15, and the input signal to the discriminator 13 is fed back to the control circuit 16 through the switch circuit 15. Thus, the level of the signal inputted to the control circuit 16 is independent of the logic of the signal and is changed by only the level of the receiving signal.

Title: Error compensated current transformer
Inventor: TAKAHASHI HARUO
IPC: H01F38/28
Filed: 1979-09-20
Abstract: PURPOSE:To permit an error compensated current transformer that compensates the specific error and the phase angle error independently of each other to more accurately perform the function by providing a back-turn winding. CONSTITUTION:An auxiliary iron core-side secondary winding 7 having a turn number N3 is provided with a winding 21 to back-turn the winding 7. Thus, the secondary induced voltage varies corresponding to the back-turn ratio. On the other hand, a main iron core-side secondary winding 4 having a turn number N2 is not back-turned. Consequently, the specific error has no change. Varying the induced voltage without changing the specific error permits the exciting current produced by the induced voltage to vary, resulting in the variation of the phase angle error. In other words, providing the winding 7 with the back-turn winding 21 permits the phase angle error to be removed without changing the specific error. Similarly, the specific error can be compensated independently. This permits a more accurate error compensation.
