Title: Lubricating device for bearing
Inventor: NAWAMOTO HIROTSUNA
IPC: F16N7/30
Filed: 1998-08-11
Abstract: PROBLEM TO BE SOLVED: To enhance the lubricating performance and the performance of a bearing by surely feeding lubrication oil to a bearing, and by enhancing the cooling operation for the bearing with the use of air jetted from a nozzle. SOLUTION: A tapered divergent nozzle 4 for jetting lubrication oil to a bearing 2 together with air is formed in an outer race spacer 3. The cross-sectional area of the tapered divergent nozzle 4 is sharply decreased from the inlet part to a throat part having a minimum cross-sectional area, and is moderately increased from the throat part to the outlet part, and accordingly, the flow speed of the air is accelerated up to a sonic speed before the throat part, and then is accelerated up to a supersonic speed in the outlet part. With this arrangement, the energy of the jet air containing the lubrication oil can be enhanced, and accordingly, the lubrication oil can be surely fed.  Further, the nozzle 4 allows the air to be adiabatically expanded, and accordingly, the temperature of the jetted air can be lowered to a value which is lower than the temperature of the air before passing through the nozzle. Thus, the cooling effect for the bearing 2 can be improved. Accordingly, it is possible to aim at improving the lubricant performance, reducing the frictional loss of the bearing and enhancing the reliability of the bearing, and the like.

Title: Heating method and heating furnace for hot rolling line
Inventor: OISHI KIYOSHI
IPC: C21D9/00
Filed: 1986-09-25
Abstract: PURPOSE:To execute heating with high thermal efficiency by making one-row operation of a heating furnace if the treating capacity of a rolling stage in succession to a heating stage is enough to be covered by one row of the heating furnace and conversely, making two-row operation of the heating furnaces if the treating capacity of the rolling line is higher. CONSTITUTION:The operation is made by using only one row of the heating furnace 3 or 4 and the unused row is put out to reduce energy consumption in the case of treating the ingots having small heating load in the heating furnace T. On the other hand, the two rows of the heating furnaces 3, 4 are used so that the treating capacity meets the treating capacity of the rolling stage if the ingots (CCR materials) and high-temp. heat retaining materials, etc., loaded into the heating furnace T after cooling have the large heating load. The materials having the larger heating load are charged in precedence to the other row and are preheated while the materials having the smaller heating load are treated in one load at the time of changing the operation from one-row to two-row operation. The waiting for materials to be heated in the rolling stage is thereby prevented.

Title: Temperature controller for fixing device
Inventor: KUMON TOSHIHIKO
IPC: G05D23/00
Filed: 1987-09-09
Abstract: PURPOSE:To preclude a fixation defect and an offset as much as possible by turning off a rotary driving means when a 1st set temperature is reached and turning off a heating means as well when a 2nd set temperature high than the 1st set temperature is reached. CONSTITUTION:The surface temperature of a heat roller 22 is detected by a temperature sensor 24 and when the temperature reaches the 1st set temperature T1, a rotation signal S3 is turned off, so that the heat roller 22 and a pressure roller 23 stop from rotating. Then the surface temperature of the heat roller 22 is detected and when the temperature reaches the 2nd set temperature T2, the rotation signal S3 and a heating signal S2 are turned off, so that the heat roller 22 and pressure roller 23 stop rotating and the heating is stopped, thus completing temperature control. Consequently, a warming up time is short and the surface temperature becomes high and uniform enough not to cause the fixation defect, so the fixation defect is precluded and the problem of picture quality is precluded as much as possible.
