Title: Method for estimating profile of charged material in blast furnace
Inventor: AZUMAGUCHI HIROMI
IPC: C21B5/00
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To estimate a profile of charged material at this time in a high precision and a short time by dividing the charging time of charging material from a large bell after actually measuring the profile of charged material at the last time and obtaining dropping position of the charged material to each position in the radius direction in a furnace in each divided time zone. SOLUTION: At the time of estimating the profile of the charged material into a bell-type blast furnace, firstly, after actually measuring the profile P0 of the charged material at the last time as the basis, the charging time of the charged material 2 from the large bell 1 is divided. Successively, the position of the large bell 1 and the position of a movable armor 3 in each divided time zone, and the dropping position of the charged material 2 to each position in the radius direction in the furnace in each divided time zone from the charging profile P0 are obtd. This dropping position is overlapped and the max. value in overlapped divided time zones is made to the dropping position to each position in the radius direction in the furnace and the profile P of the charged material at this time is estimated and drawn.  By this method, the profile of the charged material at this time can be estimated in the high precision and the short time.

Title: Inline-type electron gun
Inventor: YOSHIDA NAOHISA
IPC: H01J29/50
Filed: 1985-08-14
Abstract: PURPOSE:To correct the imbalance of the diffractive force of a convergent electrode by making the point on which an electron beam admitted by a central penetrating hole is converged closer to the main lens than the points on which electron beams admitted by side penetrating holes are converged. CONSTITUTION:Recesses which are continuous with penetrating holes and formed on the surface facing a convergent electrode (G3) reduce the divergence angle of elec tron beams admitted by the penetrating holes, make the crossover point of the electron beams apart from the cathode surface (closer to a main lens 12) and make the point on which the electron beams are converged by the main lens apart from the main lens. This effect increases as the well surface formed by the recess is closer to the penetrating hole, as the penetrating hole is longer and the recess is deeper (as the wall surface is higher). Therefore, the X and Y axis dimensions of a central recess 17g are adjusted to be larger than those of side recesses 17r and 17b, so that the points on which the electron beams (R) and (B) are converged become closer to the main lens 12 than the point on which the elctron beam (G) is converged. Consequently, it is possible to correct the imbalance of the main lens 12 by properly adjusting the ratio of the dimensions of the central recess 17g to those of the side recesses areas 17r and 17b.

Title: Disk parts with shaft and formation thereof
Inventor: TAKEDA KUNIO
IPC: B21K1/42
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To efficiently form a disk parts with shaft without developing void (crack) at a low cost. SOLUTION: Temp. distribution just before forming is the highest temp. at a portion S0 corresponding to the outer peripheral part of the disk part after forming, and becomes gradually lower temp. toward the center part SI in the radial direction and toward the end parts in the shaft direction from the highest portion. Then, at the time of upset-forming a bar-like blank in the temp. distribution, such as the above state, the highest temp. portion is shifted to the outside without leaving in the center part.  Further, simultaneously, the temp. is ordinarily raised with heat-generation according to the compressive deformation to the center part SI in the radial direction during forming, but in this case, since the portions 10a corresponding to the shaft parts at the lower temp. exist at the upper and the lower parts of the center part SI in the radial direction, these portions 10a are acted as chiller to restrain the heat-up at the center part SI in the radial direction.

Filed: 1983-09-28
Abstract: PURPOSE:To suppress rolling of chassis under engine stop, in an internal-combustion engine for car, by prohibiting spark discharge irrespective of production of firing control signal when the engine rotation is lower than specific level which is lower than the idling rotation. CONSTITUTION:Upon dropping of engine rotation below specific level lower than idling rotation, the time interval between production of positive timing pulse from a pulser coil 11 and production of negative timing pulse is lengthened against the time interval when the collector voltage of transistor Q3 in prohibition circuit 15 is H to bring the transistor Q2 into on-state when producing the negative pulse or at the firing timing thus to prohibit firing function. In other word, at the firing timing when the firing control signal will transfer from H to L, power transistor Q1 is turned off to produce counter electromotive force in an ignition coil 6, but since it is fedback through transistor Q2, Zener diode ZD1 to the base of power transistor Q1, secondary voltage of coil 6 is suppressed thus to never cause discharge from the firing plug 7, resulting in suppression of rolling of chassis under engine stop.
