Abstract: PURPOSE:To simplify the structure and stabilize the performance by champing or detecting a hook on the side of a dump body and clamp pins of a dump door by means of elastic members fitted to the axis of a bell crank that hook parts are composed of. CONSTITUTION:When a dump body 1 is inclined and a dump door 4 is opened, a bell crank 9 is put under a free state, the development angle of the 1st arm 12 and the 2nd one 13 takes the maximum when the 2nd arm 13 comes in contact with a stopper 19.

Title: Rolling method at varying plate thickness
Inventor: MIYASAKA KIYOTO
IPC: B21B1/22
Filed: 1981-09-25
Abstract: PURPOSE:To permit continuous rolling without changing the setting even when the thickness on an inlet side changes by setting width in such a way that the same draft is attained at the point where the elastic curve of a rolling mill and the plastic curve of the plate intersect despite the change in the thickness when the thickness in continuous rolling wherein upper and lower rolls of different speeds are wrapped on the plate changes. CONSTITUTION:The rolling in the case in which the thickness of a plate material on an inlet side is changed from h1 and h2 and the plate before changing of the thickness and the plate after changing of the thickness are rolled at the same draft (r) is accomplished as follows: Prior to changing of the thickness, the plate material is reduced down from h1 to (1-r)h1 in such a way that the point where the elastic curve T of the rolling mill and the plastic curve C1 of the plate comes at a rolling point (a). After the changing of the plate, the plate slips in the wrapping parts and the plastic curve C2 does not form an intended curve in actuality. In order to eliminate the inconvenience of a change in the draft on account of said slipping, the width of the plate is changed so that the rolling point (b) comes at the point where the curve T and the curve C2 intersect. In other words, the the curve C2 changes with the widths of the plate and therefore the width to provide such rolling load under which the point (b) comes to the position where said point is at the same draft is beforehand determined and the width is selected set deliberately when the thickness changes.

Filed: 1987-06-17
Abstract: PURPOSE:To form a ferrite without dispersion of a characteristics, by blending a ferric hydroxide cake preserved at a specific pH or below with a ferrous ion-containing solution or ferrous hydroxide cake and aging the resultant blend. CONSTITUTION:A ferric hydroxide cake preserved at pH <=5 is prepared as a raw material for ferric hydroxide.

Abstract: PURPOSE:To secure the good bonding performance by a method wherein a thermal shield plate to shut off the heat from a heater block is installed between a tape guide and the heater block in order to prevent a tape and a lead from being deformed. CONSTITUTION:A metal plate 9 having an area which is sufficient to mount an IC chip 6 is placed on a heater block 8 and is fixed through a vacuum suction hole 10; the IC chip is fixed by vacuum suction through a vacuum suction hole 11 of the metal plate 9. Because the IC chip 6 can be heated at a temperature nearly equal to that of the heater block 8; the IC chip 6 is set to a prescribed temperature by controlling the temperature of the heater block 8. In addition, while the heat is dissipated from the surface of the heater block 8 where the metal plate 9 is not mounted, a high temperature of tape guides 2a and a tape 3 can be suppressed by using a thermal shield plate 7. By this setup, it is possible to prevent that the tip of an inner lead 4 hangs down due to expansion of the inner lead or that a bonding operation becomes defective due to a thermal deformation of the tape 3.
