The Japan Atomic Energy Agency was formed October 1, 2005 by a merger of two previous semi-governmental organizations. While it inherited the activities of both PNC and JAERI, it also inherited the nickname of JAERI, "Genken" 原研, an abbreviated word for "nuclear research".On April 10, 2007, JAEA officially joined the GNEP alliance. The other members in the alliance are Areva, Washington Group International and BWX. It is expected that the experience gained from the Rokkasho centrifuge enrichment plant will be a key contribution from JAEA. Wikipedia.

A starting device for feeding a quantity of fuel from the fixed-quantity fuel chamber to an intake passage during start-up having a manually operated primary pump for suctioning/pumping fuel and arranged on a fuel introduction path connected along a fuel-feeding path; and a fixed-quantity fuel chamber for temporarily storing fuel delivered from the primary pump. An internal wall of the fixed-quantity fuel chamber undergoes elastic displacement, allowing its internal capacity to expand/shrink within a predetermined range; the fixed-quantity fuel chamber is connected to a fuel delivery path that communicates with the intake passage side and has a manually operated open/close valve; the valve is opened in a state in which, due to the primary pump being operated, the fixed-quantity fuel chamber is filled with a predetermined quantity of fuel while enlarging its internal capacity, whereby it shrinks due to an elastic contraction force and the fuel.

A fuel injection device for smooth discharge of a gas accumulated therein comprising a fuel pump, a solenoid valve for injecting pressurized fuel into the intake passage of an engine, a high-pressure fuel passage extending from the fuel pump to the solenoid valve and has a medially positioned constant-pressure chamber, and a fuel return passage connected to a fuel return pipe, with the fuel return passage extending from the constant-pressure chamber and having a medially positioned priming pump. The constant-pressure chamber is configured with the top wall in the upper space thereof disposed above the opening of the high-pressure fuel passage opposite the solenoid valve, the fuel return passage opens into the upper space at a position above the opening of the high-pressure fuel passage, and the gas accumulating in the constant-pressure chamber is discharged from the upper space toward the fuel tank via the fuel return passage.
