Filed: 1994-05-18
Abstract: PURPOSE:To obtain a casting die device, in which even in the case of providing a pressurizing means for filling material in a cavity, an ejection pin is unnecessary to be made the long length and the degree-of freedom of the setting place can be held. CONSTITUTION:Pin plate 8 for fixing the ejection pins 10 are fixed so as to be apart from a C plate 7 through C plate connecting rods 14 and C plate connecting plates 13.

Title: Method for preparing ceramic slurry
Inventor: KOJIMA NOBORU
IPC: B28C1/04
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To easily prepare a homogeneous ceramic slurry having required characteristics. SOLUTION: This method for preparing a ceramic slurry is to disperse a B2 O3 -containing glass component in a solvent containing ethylene glycol or methanol, to add an anionic dispersing comprising an aliphatic alcohol sulfate as a main ingredient, then, to add BaO-Re2 O3 (Re: a rare earth element)- TiO3 -based ceramic, and to disperse it. Thus, the anionic dispersant acts to concentrate on the BaO-Re2 O3 -TiO2 -based ceramic and the BaO-Re2 O3 -TiO2 is homogeneously dispersed, the reaction of a boron compound in the glass component with the anionic dispersing is reduced to decrease dilatant precipitates and characteristics such as a dielectric constant, a shrinkage factor, etc., have little scattering.

Title: Multiple interference fit metallic die
Inventor: MATSUNAGA SHUICHI
IPC: B21J13/02
Filed: 1986-06-03
Abstract: PURPOSE:To heighten an allowable internal pressure by providing a peripheral direction stress softening means on a clamping ring, and also, forming it to a shape for incresing a compressive force by varying its length in the axial direction. CONSTITUTION:A clamping ring 3 is divided completely by a gap 6, and generation of a stress in the peripheral direction for repelling the clamping from clamping rings 1, 2 is relaxed, therefore, the clamping force from the clamping rings 1, 2 is not attenuated by a stress generated in the ring 3 but transferred efficiently to an insert 4. As for the clamping ring 3, when its length in the axial direction is denoted as Ho and Hi, in the outside peripheral side and the inside peripheral side, respedtively, and its diameter is denoted as Do and Di, in the outside peripheral side and the inside peripheral side, respectively, a compressive force Pi which is generated when a compressive force Pi has been received in the outside peripheral side becomes Pi>Po since Do>Di, and also, Ho>Hi. In this way, when the ring 3 is clamped by the clamping rings 1, 2, the compressive force is increased, a pre-load is given by clamping more strongly the insert 4, and an allowable internal pressure of a multiple interference fit metallic die is further raised.
