Abstract: PURPOSE:To obtain optimum inertia supercharging of an engine in its all operational range, by independently forming each intake and exhaust system of a cylinder group, having cylinders with no neighboring firing order, and switchably connecting the exhaust pressure of each cylinder group with an intake pulsation amplifying part in any of the cylinder groups. CONSTITUTION:An engine, connecting intake systems 4-1 and 4-4 of a cylinder group, containing cylinders with no neighboring firing order, with a surge tank 8 while similar intake systems 6-2 and 6-3 with a surge tank 9, forms the upstream of each intake system as independent intake systems by intake pipes 10, 11 equipped with a throttle valve. The engine, collecting similarly pipes 5-1 and 5-4 and pipes 7-2 and 7-3 also in an exhaust system, forms independent exhaust systems by exhaust pipes 15, 16. The engine, collecting the pressure of the exhaust pipes 5-1 and 5-2 by pipes 24, 25 to be guided by a selector valve 28 into a movable partition 35 of said cylinder group through a pipe 21 when the engine is in low speed operation, amplifies an intake pulsation by the pulsation of said partition. When the engine is in high speed operation, the selector valve 28 guides the pressure acting on the intake system of the other group through a pipe 20, and the engine closes valves 32, 33 in the time of maximum intake pulsation.

Title: Switching power supply
Inventor: SUZUKI HIROYA
IPC: G01R33/02
Filed: 1981-04-22
Abstract: PURPOSE:To prevent the overcurrent, by using a WIEGAND wire to generate the pulse voltage when the output current of a power supply device exceeds the rated value and stopping the switching action with the pulse. CONSTITUTION:An input terminal 5 of the control coil of a pulse generator 10 is inserted in series to an output current circuit of a switching power supply. For the control coil, a copper wire having 1mm. diameter for example is wound around a hollow bobbin of 5mm. diameter by 20 turns and a WIEGAND wire is stored in the inside of the bobbin. At the same time, the magnetization of the WIEGAND wire is inverted when the current of the control coil reaches a level higher than several amperes in case when a permanent magnet for application of magnetic field is set at an appropriate position of the outside. Thus an intensive pulse is generated at an output terminal 3 of a pulse generating coil. This pulse is supplied to a control circuit as the oscillation stopping signal for the control circuit to obtain a prescribed overcurrent protecting function. As a result, the voltage drop due to a load current can be neglected to realize a switching power supply suited to a circuit of low voltage and large current.
