Filed: 1979-04-16
Abstract: PURPOSE:To provide sure ignition of fuel mixture, by synchronizing high-frequency ac current generated in a DC-HF.AC inverter to proper ignition time of an engine for conducting the primary winding of an ignition coil. CONSTITUTION:Commutation of a thyristor 24 is on/off controlled, being intermittently synchronized to a contact point 33. High-tension, high-frequency ac current of a DC-HF.AC inverter is applied to primary winding 26, a bridge circuit being kept conducting in two directions, from a terminal a to the other b an vice versa, in accordance with high-frequency ac current flowing in a commutating element bridge of a controlled circuit while the thyristor 24 is on, so as to induce, in secondary winding 27, high-tension, high-frequency ac current proportional to the turn ratio. Thus continous discharge of high energy, which produces an arc piller with a large arc cross section in a clearance of an ignition plug 28, lasts for the full length of ignition time.

Title: Air flow measuring device
Inventor: IGARASHI SHINYA
IPC: G01F1/684
Filed: 1994-03-17
Abstract: PURPOSE:To reduce measuring errors and output noise by providing a wall, approximately parallel with a main flow direction, in a main air passage at the outlet part of an auxiliary air passage. CONSTITUTION:At the outlet confluence part 1d of an auxiliary air passage, water flowing out from the auxiliary air passage flows out in a range limited by a flow limiting wall 10. The fluctuation in a flow direction that can be generated without the wall 10 is thereby small, and the inertial force of the flow is larger than that in the case of having no wall 10, so that the flow becomes stable. On the other hand, even in the case of large turbulence such as turning flow being generated to the flow of a main air passage, the flow becomes stable with directionality restricted by the wall 10 at the outlet confluence part. The wall 10 thus stabilizes both the flow flowing out from the auxiliary air passage 1 and the flow of the main air passage at the confluence part, so that the change of the confluence part is small, and the flow change of a flow measuring part 1b is also small. The measuring error and output noise of an air flow measuring device can be thereby reduced.
