Title: Four-stroke multicylinder engine
Inventor: MATSUMOTO HIROMITSU
IPC: F02B31/00
Filed: 1979-07-05
Abstract: PURPOSE: To prevent unstable combustion caused by a reverse flow of the atmosphere from an exhaust passage into a combustion chamber by providing near a  suction valve a blast nozzle biased to one side with respect to a cylinder axis in a  combustion chamber.  
     CONSTITUTION: In a four-cycle multicylinder engine, a secondary air passage with a check valve 26 in it opens into an exhaust port 2 to lead the atmosphere into the exhaust port in aid of pulsated exhaust pressure. A blast nozzle 36 eccentrically faced to a cylinder axis in each combustion chamber 15 is formed near a suction valve 17 inside a suction port 5. The blast nozzles 36 for cylinders each are connected to an auxiliary passage 37 to be communicated with each other. Under low load operation of an engine where much atmosphere carried into the exhaust passage 2 to flow back into the combustion engine 15, high speed suction current supplied from the blast nozzle is swirled around the axis of a cylinder 12 to promote combustion. Thereby feeding secondary air improves unstable propagation of flame in the combustion chamber 15.

IPC: A61B5/055
Filed: 1990-03-31
Abstract: PURPOSE:To keep a subject off undue unease during an inspection along with a reduction in leakage magnetic field by connecting two magnetic poles as opposed to each other with a magnetic member in a direction opposite to a space therebetween so that the magnetic member forms a return path of a magnetism flowing through the space. CONSTITUTION:Two cylindrical magnetic poles 1 and 2 are arranged as opposed to each other being separated at a specified space and a cylindrical superconductive coil 3 is arranged on the lower magnetic pole 2 surrounding the perimeter thereof. Then, these magnetic poles 1 and 2 are connected on the side opposite to the space formed by the opposite arrangement of the magnetic poles 1 and 2 and connected to a magnetic member 4 made of a ferromagnetic material. In the above arrangement, a magnetic flux formed by a current flowing through the superconductive coil 3, first, concentrates on the lower magnetic pole 2, flows toward to an upper magnetic pole 1 and returns to the magnetic pole 2 passing through an outer shell section of the magnetic member 4, the magnetic member 4 serves as a return path of the magnetic flux flowing through a space between the magnetic poles 1 and 2. As the magnetic passage is closed except for the space between the magnetic poles 1 and 2, a magnetic field to be leaked outside can be reduced. This also provides a sense of release as compared with the conventional type using a long cylindrical magnet to house.
