Title: Fuel injection pump
Inventor: NAGASE MASAOMI
IPC: F02D41/40
Filed: 1983-07-08
Abstract: PURPOSE:To enable positions of a spill ring and a timer piston to be correctly detected, by inputting a high frequency signal from position sensors to a signal processing circuit through a relatively short wiring. CONSTITUTION:A signal processing circuit 1B is integrally mounted to an injection pump main unit 1A and connected to a control circuit 39 through a wiring 30 with a spill position sensor 31 and a timer position sensor 33. A distance between each sensor 31, 33 and the signal processing circuit 1B is very small as compared with the distance between the signal processing circuit 1B and the control circuit 39. In this way, positions of a spill ring and a timer piston are correctly detected by decreasing the possibility of a noise overlapping on a high frequency signal from the sensors 31, 33.

Abstract: PURPOSE:To prevent completely illumination light from being reflected by a slit and incident and to obtain image of high quality by employing a plane surface opposite the slit of the 1st Fresnel lens of a copying machine with a function which forms a white frame at the end part of a projection image, and then forming plural small lenses which have a specific Fresnel lens on the opposite surface from the plane surface. CONSTITUTION:The 1st Fresnel lens F1 is so formed that plural small lens surfaces (c) and (d) which have different Fresnel angles and make projection light incident in parallel to the axis of a photosensitive drum consist of a top- side half surface 12 and a reverse-side half surface 13 symmetrical about an optical axis 11 set at the center part of the Fresnel lens body 10. Therefore, reverse surfaces (e) and (f) of a surface where the small lens surfaces (c) and (d) of the Fresnel lens body 10 are arrayed annularly along the lengthwise direction of the photosensitive drum are formed in a plane shape. Consequently, the illumination light l which is irradiated by an original illumination lamp 9 and strikes on the small surface (c) of the reverse half surface 12 is reflected regularly in direction deviating from the direction of the slit S as shown by an arrow A.

Abstract: PURPOSE:To quickly operate and control a reactor core by packing an upper area with a neutron moderator and flowing cooling water to a lower area from the lower part of the core to flow it out to a cooling area from an aperture part provided in the upper end part. CONSTITUTION:The upper area is packed with a neutron moderator 5. Light water is flowed from the lower part of the core in a lower area circular pipe structure and is flowed out from an aperture part 12 to a cooling area 8. Light water in the cooling area 8 is flowed in from the lower part of the core and is heated by heat generation of a fuel rod in a core part, and voids are generated by boiling.
