Title: Brush holding device for commutator motor
Inventor: SONODA SOICHI
IPC: H02K13/00
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To prevent the floating of a pigtail support so as to improve the workability of assembling work of a brush holding device by providing one or more locking holes or locking projections on the side face of the pigtail support and the surface of the support on which the brush of a brush shank slides. SOLUTION: When a brush 2 and a spring member 9 are inserted into a brush shank 4 and, in addition, a pigtail support 3 is inserted into the shank 4 by the finger, etc., an engaging project 6 provided on the support 3 is engaged with an engaging hole 7 provided on the shank 7. Then the hand is separated from the support 3 and a cap 10 is screwed on the threaded section 12 of a brush holder 5 and tightened. When the switch of a motor is turned on, an electric current flows to the shank 4 through a lead wire 14 and a garter spring 13 and further flows to a commutator 11 from the shank 4 through the brush 2. As a result, an armature rotates.

Title: Core for water cooled type nuclear reactor
Inventor: REONHARUTO KUNIIRURIEMU
IPC: G21C5/06
Filed: 1989-11-24
Abstract: PURPOSE: To fix a positioning pin without requiring any fixing nut by providing the positioning pin with a center gear penetrating the pin while tapering the center gear at the end part remote from a fuel assembly. CONSTITUTION: Since a positioning pin and a plug 24 in the region of a step gear 23 have conical shape, a groove 25 is pressed against the wall of a gear 18 and connected firmly therewith. A force acting on the plug through a tappet 32 is selected depending on the difference of hardness between the material of a grid plate 9 and material of the groove 25. The firm connection is not loosened because of automatic fixing action of conical connection between the plug and step gear. Furthermore, a peripheral groove 34 serves as a safety unit for preventing the connection from loosening because the groove 34 receives a slight inflation 35 of step gear 23 being formed upon relative movement of the plug.

Filed: 1990-11-09
Abstract: PURPOSE:To realize a high load combustion in a combustion chamber of a small volume by blowing out and supplying the fuel gas from both sides with respect to a collision space of the combustion air out of collision air blow-out ports that are mutually opposed vertically. CONSTITUTION:The combustion air is blown out from collision air blow-out ports 21 and 22 that are mutually opposed vertically at the speed which is several times as high as the combustion speed, and the fuel gas is jetted out from fuel gas blow-out ports 24 and 24 on both sides. The combustion air collides in the center to create a strong turbulence. The air and fuel are mixed in a short time by supplying the fuel gas to this turbulent space and the combustion proceeds violently. The flames are held stably in the space near the air collision point 23, and the collision air blow-out ports 21 and 22 and the fuel gas blow-out ports 24 and 24 do not hold flame. With this arrangement under the strong turbulence the combustion is efficient and a high load combustion in a narrow space is realized. Further, while the burned gas and unburned gas are mixing by the strong turbulence the unburned component burns and low NOX is realized by the recirculation effect of the exhaust gas.
