Title: Method of controlling supplied quantity of fuel to internal combustion engine
Inventor: MIYAGI HIDEO
IPC: F02D41/06
Filed: 1980-09-01
Abstract: PURPOSE: In a method of effecting control to increase the supplied quantity of fuel depending on the warmed state of an internal combustion engine at its start and decrease the supplied quantity with the lapse of time after the start, to improve the operation performance of the engine, by effecting control to reduce or augment the increment of the supplied quantity of fuel at the start.  
     CONSTITUTION: When a signal from a starter 50 is starting, an increment coefficient SE for starting is determined from the signal of a cooling water temperature sensor 42. The relationship between the coefficient SE and the water temperature is a known one. An increment coefficient ASE after the starting is determined according to a formula (SE-a.t) where (a) denotes a constant and (t) denotes time from the end of the start. The rotational frequency N is determined in terms of the signal of a rotational angle sensor 38. A function f(N)=b/N, which is inversely proportional to the rotational frequency N and in which (b) denotes a constant, is calculated. The increment coefficients SE, ASE are multiplied by the calculated value to determine a coefficient ASE' compensated by the rotational frequency N. The coefficient ASE' is used to calculate fuel injection time. This results in enabling control for reducing or augmenting the increment depending on the rotational frequency N to improve the feeling of driving at the start and throughout a short time after it, prevent smoldering on a spark plug and reduce fuel consumption.

IPC: G02B27/00
Filed: 1990-05-14
Abstract: PURPOSE:To prevent dust sticking on a lens surface from being imprinted on a film by moving and displacing a plane plate by a driving means at right angles to an optical axis associatively with the shutter releasing operation of a shutter. CONSTITUTION:When the shutter is released, an engagement member 5 disengages from the plane plate 1 associatively and begins to be displaced upward with the spring force of a spring member 3. The shutter begins to open at the start of the movement of the plane plate 1. The spring constant of the spring member 3 is so set that the plane plate 1 is displaced continuously in the shutter releasing time. Namely, the plane plate 1 is arranged between a lens final surface and the film surface to cut off dust, etc., from the film side by the plane plate 1 even if the dust is entered. Consequently, the shadow of the dust, etc., becomes inconspicuous and is prevented from being imprinted on the film.

Filed: 1982-07-13
Abstract: PURPOSE:To improve the precision of a voltage dividing circuit composed of a resistance network and a reference voltage source by adjusting the resistance values of mutual connecting conductors which connect resistors mutually in a specific way. CONSTITUTION:Resistors 11-13 with a resistance value R are connected to a reference voltage source in series.
