Title: Fuel injector for internal-combustion engine
Inventor: MAEDA HIDEKI
IPC: F02M69/00
Filed: 1983-06-21
Abstract: PURPOSE:To reduce fuel consumption and improve stability of an engine in low load by providing a sub-fuel injection valve driven in the low load in an auxiliary intake path. CONSTITUTION:Fuel is supplied mainly from a main fuel injection valve 12 and a sub-fuel injection valve 17 is driven in low load including idling time. Air passes through a slight gap between a throttle valve 13 and the inner wall of an intake path 15 with speed near acoustic velocity in the idling time. Thus, fuel supplied to an auxiliary intake path 16 from the sub-fuel injection valve 17 is sucked out of the opening end 16b of said path 16 and atomized very satisfactorily by the high speed air flow. Also, in the low load where the throttle valve 13 is slightly opened, a comparatively large intake negative pressure acts on the opening end 16b of the auxiliary air path 16 to provide similarly satisfactory atomization.

Filed: 1978-09-11
Abstract: PURPOSE: To prevent vibration sounds at the end of cleaning blade from occurring and increase the cleaning effect, by forming a slit at the end of cleaning member pressed against the surface if electrostatic latent image carrier.  
     CONSTITUTION: A cleaning blade 22 is constituted with an elastic material having an edge at the end thereof, and is installed so that the end may be directed in the same direction as the moving direction of the surface of a photosensitive drum 1.

Abstract: PROBLEM TO BE SOLVED: To shorten the followup time of averaging circuit output and to improve reception quality by invalidizing a residual value inside an averaging circuit so as not to affect following averaging circuit outputs when the reassignment of demodulation phase occurs. SOLUTION: Based on a multipath phase retrieved by a search circuit 108, path information 113 and smoothed signals 120, 121 and 122, it is judged at a comparative judge circuit 109 whether or not phase reassignment is to be performed.

Title: Residual gas controller for internal combustion engine
Inventor: NANUN SHINICHI
IPC: F02M25/07
Filed: 1979-08-30
Abstract: PURPOSE:To effectively suppress the production of Nox, by determining the profiles of cams so that the time of opening of an intake valve and the time of closingof an exhaust valve are almost coincident with each other in a medium load range and the rate of exhaust gas return in that range is maximum. CONSTITUTION:A cam shaft 2 over a cylinder head 1 is synchronized with the rotation of an engine by a sprocket 5. A piston 7 and a cam for an exhaust valve act to an oil pressure controller depending on the degree of opening of an accelerator (the load upon the engine) to change the time of closing of the exhaust valve 11. To perform the same operation, a cam for an intake valve is mounted on the cam shaft 2. The cam 10 for the exhaust valve acts to make the time of closing of the exhaust valve 11 earlier in a medium load range. The cam for the intake valve acts to make the time of opening and closing of the intake valve coincident with that of closing of the exhaust valve 11. As a result, the rate of exhaust gas return is maximum in the medium load range and the exhaust of NOx is suppressed enough.

Title: Vibration-isolating optical system
Inventor: YAMAZAKI SHOICHI
IPC: G02B13/00
Filed: 1996-05-07
Abstract: PURPOSE: To make it possible to easily correct the image displacement on an image plane by parallel offcentering a part of optical elements constituting a vibration-isolating optical system in a direction perpendicular to an optical axis. CONSTITUTION: An imaging lens system consists successively of an focal first lens group 5, a second lens group 6 and a third lens group 7. The respective lens systems consist of one or plural elements of lenses. The second lens group 6 which is an F image plane is an imaging lens and is supported by a supporting device in such a manner that the parallel offcentering in the direction perpendicular to the optical axis of the system is free. The second lens group is two- dimensionally moved by actuators 3, such as piezo elements. These actuators 3 drive the second lens group 6 laterally without inducing mechanical interference with the vertical movement. A vibration detecting sensor 4, such as accelerometer or gyroscope, detects the vibration in the vertical direction and the vibration in the lateral direction.  The detection quantity is inputted to the respective actuators 3 and, therefore, the second lens group 6 moves in the direction where the detected quantity decreases to zero according to the two-dimensional vibration, thereby canceling the shake of the image plane.
