Title: Magnetic recording medium
Inventor: MAEZAWA AKIHIRO
IPC: C09D5/23
Filed: 1992-04-17
Abstract: PURPOSE:To enhance smoothness and durability by forming a magnetic recording layer contg. ferromagnetic powder dispersed in a binder on a nonmagnetic substrate, regulating the thickness of the recording layer to <=0.7mum and previously treating the solid powder existing in the recording layer with a coupling agent. CONSTITUTION:A magnetic recording layer contg. ferromagnetic powder dispersed in a binder is formed on a nonmagnetic substrate. The thickness of the recording layer is regulated to <=0.7mum. The solid powder existing in the recording layer is previously treated with a coupling agent having an amino group, an epoxy group, a hydroxyl group, a phosphoric acid group or an isocyanato group as a functional group which reacts with an org. matrix. When the coupling agent has an alkoxy group, the number (X) of the carbon atoms of the alkoxy group is allowed to satisfy Y<X<3Y (where Y is given by dividing the ionic radium of the core atom by the distance between carbon atoms). By this structure, satisfactory dispersibility and coatability are ensured and a magnetic recording medium excellent in smoothness and durability is obtd.

Title: Rib for synthetic resin pallet
Inventor: ASAI CHIHARU
IPC: B65D19/24
Filed: 1995-03-30
Abstract: PURPOSE: To mold a synthetic resin pallet or a synthetic resin vessel in which the surface formed by a rib is flat without deformation by forming it of a thin part and a thick part and a vertical sectional shape perpendicular to a longitudinal direction symmetrical to a horizontal line. CONSTITUTION: The rib 2 of a synthetic resin pallet is formed of a thin part and a thick part in such a manner that the shape of the vertical section perpendicular to the longitudinal direction is symmetrical to a horizontal line I-I. The sectional shape of the rib 2 is formed at the center 2b substantially in a square shape, at the upper and lower parts 2a, 2b via the center 2b in the same shapes in such a manner that the end is a thin substantially triangular shape. Thus, the deforming force which tends to bend upward in the half region of the rib 2 above the line I-I generated by cooling the pallet after injection molding and the deforming force which tends to bend downward in the half region of the rib 2 below the line I-I cancel to each other at the line I-I as a boundary, thereby preventing the deformation.

Title: Gas fired multitubular once-through boiler
Inventor: MATSUI KOICHI
IPC: F23C13/00
Filed: 1995-04-24
Abstract: PURPOSE: To prevent the generation of back firing by a method wherein ceramic grain materials are filled between specified rows of a water tube wall in a combustion chamber to form a relatively thin combustion layer and a premixed gas is burned in a surface diffusion within the combustion layer to eliminate forced circulation cooling with the restricting of energy consumption after the stopping of combustion.

Title: Operating method for blast furnace
Inventor: HAYASHI YOUICHI
IPC: C21B5/00
Filed: 1978-08-15
Abstract: PURPOSE:To execute the optimum operation in order to stabilize the furnace condition, by classifying the feed stocks for the blast furnace according to specified respective particle sizes, by selectively setting the charging rate for respective particle sizes, and by charging the feed stocks uniformly to the sectional area or locally selectively into the circumferential zone of the furnace. CONSTITUTION:The feed stocks for the blast furnace are held in the stock bankers after being classified according to the specified respective particle sizes. For instance, the coarse coke C1, the medium sized coke C2, the fine sized coke C3, the coarse ore O1, the medium sized ore O2, and the fine sized ore O3, are held in the separate bankers 1 respectively. Depending on the specified operational instruction, the specified amount of feed stock of the specified class is taken away through the delivery feeder 2, and is sent to the hopper of the furnace top through the conveyer 3, and the hopper 4, and is charged into the specified position in the furnace by the movable arm or the swivel chute, etc. Correspondingly to the intended purpose for stabilizing the furnace condition, for instance when the improvement of the rate of reduction of the ore is intended, the coarse or the medium sized feed stocks are charged uniformly over the sectional area of the furnace, and also the medium sized or fine sized ones are charged nearby the furnace wall. According to this method, the flattening of distribution of the gas flow is achieved, and the rate of reduction of the ore is improved.
