IPC: F01N3/24
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To obtain a multiple cylinder engine performing an engine operation for more strengthening the protection of a catalyst converter when miss fire is generated in the engine. SOLUTION: A multiple cylinder engine having a catalyst converter at an upstream position of a turbo installation portion of an exhaust passage is provided with a miss fire detection means for detecting miss fire and a miss fire fail-safe control means for performing a control to suppress a rise in the temperature of a catalyst converter when the miss fire is detected. The accidental fire fail-safe control means is provided with a miss fire cylinder specifying means for specifying a miss fire cylinder among multiple cylinders, a miss fire cylinder fuel cutting means for enforcing fuel cut for the miss fire cylinder and an unburned gas exhaust preventing means for performing a control to prevent exhaust of unburned gas from cylinders except the miss fire cylinder.  As a result, exhaust of unburned gas is prevented from also the cylinders except the miss fire cylinder after miss fire and unburned gas flowing into the catalyst converter is extremely reduced. Therefore, a rise in the temperature of the catalyst converter caused by unburned gas is suppressed and the protection of the catalyst converter is strengthened.

Title: Steering force control device of power steering device
Inventor: SUZUKI MIKIO
IPC: B62D5/22
Filed: 1986-03-28
Abstract: PURPOSE:To ensure the responsive feeling at a high speed by providing a fluid force applying means applying the fluid pressure proportional to the gear- generated pressure to a diversion control valve in the radial direction against its valve stem. CONSTITUTION:A fixed flow Q of pressure oil from a feed pump 60 is divided and controlled into a flow QG to a servo valve 30 side and a flow QR to a reaction mechanism side by a diversion control valve 1. When a handle is turned at a high speed, the gear-generated pressure PG of the servo valve 30 is increased, and in response to it, the gear-generated pressure PG is guided to a guide port 40, thus pressing the outer diameter face of a spool (valve stem) 5 in the diameter direction. The outer diameter face of the valve stem 5 on the opposite side to the pressed side of the guide port 40 is pressed to the housing inner wall face of the control valve 1 by this pressing force, and the sliding resistance of the valve stem 5 for its axial shift is increased. Accordingly, the diversion flow QR from a discharge port 4 to a reaction chamber 55 is increased in proportion to the gear-generated pressure PG, the reaction oil pressure PR is increased, and the responsive feeling is ensured.

Title: Slide transformer
Inventor: TSUCHIYA AKIRA
IPC: H01F29/06
Filed: 1982-04-28
Abstract: PURPOSE:To make it easy to manufacture and reduce the size of a transformer of such a type wherein a flat and square conductor is wound around a winding frame as it is being insulated and a sliding element is brought to contact with the sliding surface of the conductor by such an arrangement wherein 2 sides or 3 sides of the conductor including its side opposing to the winding frame are tightly and closely covered with an insulating member. CONSTITUTION:Two or three sides of a flat square conductor 5 including its side opposing to a winding frame are tightly covered with an insulating member 6 of which thickness is made larger. If the conventional resin coating such as formal enamel is used as the insulating member 6, its thickness cannot be made larger, therefore, resin particles are caused to melt and adhere to the surface of the conductor with such portions of the conductor that are to be exposed naked covered with masks. In this manner, a main winding 7 of which surge resistivity is raised by making the thickness of the member 6 larger is obtained, and this winding is tightly wound around a waiting frame 8. By this arrangement, the manufacture of a transformer becomes very easy and when the winding is wound around an iron core, insulation process is no longer required.
