Title: Fuel injection quantity controller of supercharged internal-combustion engine
Inventor: ONAKA HIDEMI
IPC: F02D41/02
Filed: 1984-07-27
Abstract: PURPOSE:To reduce fuel consumption and improve power by detecting a supercharged state of a supercharged engine and compensating quantity of fuel injection in accordance with the detected state. CONSTITUTION:An engine 2 having a supercharger 1 is provided with a supercharged-state detecting means 3 which detects both pressure of feed air at the downstream site of the supercharger and temperature of supercharged air. The detection signal producd from said means 3 is input to a fuel injection quantity compensating means 4 for calculation. The fuel injection quantity is compensatorily computed by an operating means 5, which calculates the reference fuel injection quantity on the basis of parameters relating to revolution number, intake quantity and so forth. A fuel injection valve 6 is then driven via a driving means 7. If supercharged pressure may be varied due to variation of atmospheric condition and fluctuation in performance of the supercharger, fuel quantity may be compensated in accordance with the variation. Creation of knocking and increase of exhaust temperature can be therefore prevented so that fuel consumption and power can be improved.

Title: Pressure balance structure for compressor equipped with balance piston
Inventor: KIMURA TSUGUO
IPC: F04D15/00
Filed: 1980-11-05
Abstract: PURPOSE: To prevent immediate occurrence of machine damage accident even in damage of bearing by a method wherein pressure balance structure itself is provided with balance compensatory function, break of initial pressure balance is automatically corrected, and load on thrust bearing is alleviated.  
     CONSTITUTION: Suppose that, for example, pressure balance was broken to exhibit thrust load toward C direction, an axis 1 would move toward C direction, and a gap in labyrinth packing 10 be enlarged to decrease pressure of the central vacant chamber 12. Therefore, a force toward D direction in balance piston 4 is increased, the pressure balance may be maintained, and the thrust load is operated toward the direction where it decreases to disappear. Suppose that the thrust load toward D direction was also exhibited, a gap in the labyrinth packing 10 would be decreased, pressure of the central pressure chamber 12 be raised, and a force toward C direction be increased, resulting in a achievement of the pressure balance. Thus even if the initial pressure balance is broken, it may be automatically modified to alleviate the load on the thrust bearing.

Abstract: PURPOSE:To relieve the pain of a patient, by forming a cooling water hole in a main body so as to extend along the axis thereof and to be opened to the rear end part of the main body at one end thereof and to the leading end part of a blade part at the rear end thereof. CONSTITUTION:When a tooth is cut by a diamond bar 2, cooling water is supplied into a longitudinal hole 16 from the opening part at the rear end thereof and injected from the opening part of the leading end of the longitudinal hole 16 and the cross holes 17. Therefore, even when the affected part is deep, the cooling water is sufficiently supplied to the leading end part of a blade part 12 and the affected part, and the leading end part of the blade part and the affected part of a tooth cut thereby are cooled. Therefore, the leading end part of the blade part 12 is prevented from being worn at an early stage and the life of the diamond bar 2 can be enhanced to a large extent as compared with a conventional one. Since the tooth is cooled, the stimulation of a nerve due to the heat of cutting can be eliminated and, therefore, the pain of a patient can be relived.
