Title: Pressurized ventilation fan
Inventor: AKATSUKA JIYUN
IPC: F24F7/007
Filed: 1984-04-20
Abstract: PURPOSE:To improve an accuracy of a vane, eliminate a correcting step of a pitch of the vane and reduce the number of rivet press fitting steps by a method wherein an integrally formed vane plate is fixed to a substantial semisphere boss of the vane by rivets at the flat surface. CONSTITUTION:Each of the boss 7 of the vane and a vane plate 8 is attached to each other at their flat surfaces 7a and 8a, rivets 9 are passed through holes 10 and 12 for each of the rivets and then connected and fixed to each other. Thus, a rivet fitting operation is performed at the flat surface part, its jig may also be simple and it is not necessary to provide a large-sized press machine. No press fitting force may be applied to the curved surface 7b of the boss 7 of the vane and the curved surface 7b of the vane plate, resulting in that no deformation of the plate is found due to the press fitting step and so a yield of the vane can be improved. As a result, an accuracy of the vane is improved, a correcting step of a pitch of the vane can be eliminated and an efficiency of the rivet fitting operation can be improved.

IPC: E02F9/00
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To use up fuel oil in a fuel oil tank almost to the last drop without causing insufficient supply of fuel oil even though the fuel oil tank becomes aslant because of the slant at a working site and the remaining quantity of the fuel oil becomes scarce by a method wherein a fuel oil tank wherein a rubber container with its one end connected to an oil feeding port and the other end connected to a fuel oil discharge port is housed is used, and the rubber container is pressurized from the outside in the fuel oil tank. SOLUTION: A flexible rubber container 41, with its one end connected to an oil feeding port 40b and the other end connected to a fuel oil discharge port 40c is housed in a fuel oil tank 40. An air compressor 30 is driven by power from a power source and air pressurized with the air compressor 30 is sent to and stored in an air tank 31. As the pressure inside the air tank 31 comes above a specified value, the pressurized air is sent to an air supply port 40a of the fuel oil tank 40, and pressure is applied therewith to the outer circumference of the rubber container 41. As the rubber container 41 is shrinked without fail with the quantity of fuel oil decreased, the fuel oil can be used up almost to the last drop without causing insufficient supply of fuel oil even on a slope.

Title: Finishing method for pipe end
Inventor: KOBAYASHI KAZUMASA
IPC: F16L55/16
Filed: 1990-03-30
Abstract: PURPOSE:To integrally form a lining and an existing pipe and to improve water stopping property and strength by adhering the end part of the lining to the existing pipe by means of a glass cloth and resin cured at a room temperature when the inside of the existing pipe is reinforced by the lining. CONSTITUTION:In order to improve adhesion between an existing pipe and a lining, surface processing is applied on the existing pipe and the end part of the lining by means of a disc sander. Since the inner size of the existing pipe is different from that of the lining, a staged part is produced at an endmost part and therefore, a molding work is applied by a disc sander to form a gentle slope. A glass mat impregnated with resin prepared such that a main agent and a curing agent are properly blended together is then manufactured. The mat is mounted on the end part of a pipe on which lining is applied and the lined pipe is connected to an existing pipe. Thereafter, resin may be cured at a room temperature but if there is a need to shorten a time before the starting of water supply, the resin may be gradually cured from a room temperature by using a hot blast generating device. By finishing a pipe end by the above method, the lining and the existing pipe can be formed integrally and reliability on reclamation of a pipe is improved.

SOLUTION: Cold air that is cooled by a cooler 3 is circulated in a refrigerator body 1 by a fan 2. At this time, cold air is blown to a new temperature zone deep freezer 300 through a new temperature zone deep freezer blowing path 5. Further, cold air is blown to a deep freezer 200 through a deep freezer blowing path 4, and one portion of the cold air through the deep freezer blowing path 4 is further blown to an upper-edge storage room 100. Also, the return cold air of the new temperature zone deep freezer 300 is returned to the cooler 3 independently of the cold air feedback path of other storage rooms. In the new temperature zone deep freezer 300, the temperature is set to -5 deg.C or less to store foods while avoiding the maximum crystal generation zone, thus maintaining the foods in a better condition than an ice temperature room.
