IPC: E04B1/41
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To stabilize for bending deformation by erecting a restraining member between adjacent vertical materials, and being joined to each vertical material to restrain the deformation of the vertical material. SOLUTION: An installation device 1 is constituted of a base 2, a vertical material 3 fixed and erected on the base 2, an anchor bolt 4 held adjustably on the vertical material at a position in the axial direction, a template 5 joined to all the anchor bolts 4 and a restraining member 6 erected between the adjacent vertical materials 3, 3.

IPC: B29C45/73
Filed: 1987-05-19
Abstract: PURPOSE:To improve production efficiency by making temperature falls of a mold and molded product rapid and taking out the molded product rapidly, by performing molding by separating the mold into the surface part and backside part and heating only the surface of the mold with hot air at a temperature up to the vicinity of the melting temperature of plastics. CONSTITUTION:A blow-off port 5 is inserted between a core and cavity by breaking a mold. Both sides of the blow-off port 5 are composed of a punching metal having a large number of small holes. When high-temperature air 6 is sent into the blow-off port 5, the high-temperature air 6 comes into contact with the surface parts 2, 3 of a core and cavity through small holes of the punching metal and they become high temperature. However, as the backside parts 1, 4 of the core and cavity are separated from the surface parts 2, 3 through an air gap, temperatures of the backside parts 1, 4 hardly rise and the temperatures are kept low. Moreover, as the low-temperature backside parts 1, 4 of the mold come into contact with the surface parts 2, 3 of the mold by clamping the mold, the temperatures of the surface parts 2, 3 and a molded body fall rapidly and after clamping of the mold, the molded body can be taken out rapidly.

Title: Magnetic bubble enlarging device
Inventor: YAMAMOTO MITSUO
IPC: G11C11/14
Filed: 1980-09-05
Abstract: PURPOSE:To increase the working tolerance for enlargement and transfer at a low drive magnetic field region, by adding the dummy enlarger group to the side part of a transfer path adjacent to a bobble transfer path. CONSTITUTION:Dummy enlargers 51-52 are added at the side of a bubble transfer path 11 of bubble enlargers 21 and 22. As a result, the bubble enlarging force of the enlargers 21 and 22 plus the transfer force of the enlarged cord-shaped bubble toward the travelling direction 4 become substantially equal to other enlargers of the enlarger group 20. Accordingly the abnormal transfer phenomenon which is caused while the bubble is transferred from the path 11 to the enlarger 22 after enlarged by the enlarger 21 can be greatly suppressed. Thus the enlargement and transfer properties can be increased in a low drive magnetic field region.
