Title: Heat reserving method for shaft seal device of low temperature blower
Inventor: KUWATA HIROSHI
IPC: F04D29/10
Filed: 1989-04-05
Abstract: PURPOSE:To reduce cost of equipment in a lubricating system of a low temperature blower by utilizing lubricating oil for heat reserving of a shaft seal device, and by returning and recirculating the lubricating oil cooled during heat reserving process of the shaft seal device. CONSTITUTION:Lubricating oil heated upto comparatively high temperature during steady-state running is supplied into an oil box 5 from an oil inlet port 6 of the oil box 5 through a piping 9 by using an oil pump 8. Consequently, a circumference of a shaft seal device 3 is heated. The lubricating oil to be discharged from an outlet port 10 of the oil box 5 is cooled by an impeller 2 and a shaft 1 cooled by low temperature LNG recycle gas, and the oil temperature drops and becomes suitable for lubrication in a lubricating part 12. The lubricating oil cooled by heat exchange in the oil box 5 is heated again upto higher temperature through lubrication in the lubricating part 12 and is returned to a lubricating oil tank 7. Consequently, it is not necessary to preheat lubricating oil flowing into the oil box 5 by using any external heat source and, in addition, to cool the lubricating oil flowing into the lubricating part 12.

Abstract: PURPOSE:To eliminate a storing space to be added on a main body, by a method wherein a wireless remote control is stored at the space of a handle part which is not used except carrying. CONSTITUTION:When a main body 3 is placed on the floor and a wireless remote control 1 is stored, the wireless remote control 1 can be simply stored in a handle 4 by fitting it to a fixing member 5 in the handle 4.

Abstract: PROBLEM TO BE SOLVED: To take out jammed sheets and maintenance parts with both hands by preventing a closing door having been opened to a specified position from being moved to the closing direction by its dead weight. SOLUTION: A closing door 1a is mounted onto a printer main body 1 in such a way that it can be rotated around pivots 10a and 10b in two directions indicated by arrow heads X1 and X2. Twisting coil springs 12a and 12b energizing the closing door 11a to the direction indicated by the arrow head X2, are mounted onto the pivots 10a and 10b. Therefore, the closing door 1a having been opened to a specified position in the direction indicated by the arrow head X2, is kept at an open condition by means of the twisting coil springs 12a and 12b. By this constitution, the closing door 1a is thereby prevented from being moved to the closing direction by its dead weight, and a working space in the direction indicated by an arrow head X3 will never be blocked.
