Title: Manufacture of sintered ore using mini-pellet
Inventor: SUGIZAKI TAKATSUGU
IPC: C22B1/16
Filed: 1977-12-20
Abstract: PURPOSE: To increase productivity in manufacture of the sintered ore from sinterring raw material blended with mini-pellets, by drying and dehydrating previously the mini-pellets to a water content of 0W6%.  
     CONSTITUTION: In manufacture of sintered ore using mini-pellets, usual water content of raw material excepting the mini-pellets is about 5W7%, and that of the mini-pellets is much more higher, e.g., 8W13% level. For this reason, in the sintering process, the mini-pellets show selectively lag in time required for sintering with bad influence upon the sintering, e.g. uneven structure of the sintered ore. Therefore the mini-pellets having been granulated at a water content of 8W13 is dried and dehydrated prior to the blending with the sintering raw material to a water content of 0W6% (pref. 3W6%). Hereby sintered ore of excellent quality is obtained with high productivity, and the coke consumption per unit product is reduced.

Title: Centripetal fan
Inventor: YAMAGUCHI NOBUYUKI
IPC: F04D29/26
Filed: 1977-12-20
Abstract: PURPOSE: To simplify the construction and to improve the performance of a centripetal fan by eliminating the outlet guide blades and specifically determining the position of the blades of an axial-flow fan.  
     CONSTITUTION: A plural number of axial-flow fan blades 6 are mounted in equal distribution along the circumferential direction on a central opening 5 of a dynamic blade supporting end plate 4 fixed to a centripetal dynamic blade 3.

Title: Granulation of urea
Inventor: FUJITA TOSHIO
IPC: C07C239/00
Filed: 1979-11-27
Abstract: PURPOSE: To prevent the by-production biuret which is harmful to crop, in the granulation of urea from molten, urea, by adding fine urea powder to the molten urea.  
     CONSTITUTION: In the preparation of granular urea by spraying molten urea to nucleus particles (of urea) in a rotary drum, a rotary pan, a jet-stream tank, etc., fine urea powder is added to the molten urea before feeding to the granulation apparatus. The addition of the powdery urea prevents the by-production of biuret which occurs by heating and melting urea even for a short time. The mixing of the powdery urea may be carried out by melting the urea incompletely and leaving a part of the powdery urea undissolved. For example, the amount of by-produced biuret is very small even by storing urea in a melting tank at 137W132°C for 1W30min.

Abstract: PURPOSE:To enable a cutting tool to carry out machining such as cutting, etc. with high accuracy by using a piezoelectric element and an elastic body to make the holder of the cutting tool slide and further, enabling static pressure sliding in a sliding space with a static pressure feeding means. CONSTITUTION:A holder 1 receives a pressing force from a piezoelectric element 4 while also receiving a stress against the pressing force from an elastic body 5.
