Abstract: A supply magazine (1) for a sheet stack (8) comprises a lower portion (2) which is open at the top and a cover (3) which covers the lower portion (2) at least in its sheet-removal area (roller 9) and can be opened. A pressure plate (4) pivotally mounted in the lower portion (2) is biased by springs (10) which spring-bias a sheet stack (8) arranged on the pressure plate (4) in the sheet-removal area against the inner side (3d) of the closed cover (3). As a result of the sheet stack (8) being pressed against the inner side of cover (3), it is so held by spring pressure that even if the supply magazine (1) is brought into an extremely inclined position during inser­tion into the copier or removal therefrom, the sheet stack (8) cannot be displaced and no sheets can drop out. With respect to the operative posi­tion of the supply magazine (1) in the copier, the distance of the pressure plate (4) from the inner side (3d) of the cover (3) is larger than the distance of the pressure plate (4) from the operative area of the sheet-removal device (roller 9). As a result sheet stack (8) is lifted from the inner side (3d) of the cover (3) by an amount "X" so that sheets can be separated without friction being exerted on them.

Abstract: An engine speed controlling apparatus for an internal com­bustion engine (10) for controlling the engine speed of an internal combustion engine which has a means (16, 18) for governing the engine speed and in which a manipulated va­riable of said governing beans and torque are in non-linear relationships. Although a real manipulated variable and the torque are in non-linear relationships, a virtual manipula­ted variable in which an actual engine speed becomes a tar­geted engine speed is calculated assuming those relation­ships as being linear. The virtual manipulated variable is converted (by 38) to the real manipulated variable by using the actual non-linear relationships between the real mani­pulated variable and the torque, and the governor is con­trolled (by 40) on the basis of the converted real manipu­lated variable.

Abstract: The specification discloses an automatic rearview mirror control circuit which models the physiological response of the human eye to fluctuating light levels as observed in typical driving conditions. The control circuit calculates an ambient light signal representative of light levels within the driver's field of view and a rear light signal representative of light levels in a direction generally incident to the reflective element. The reflectivity of the reflective element is controlled to optimized rear image information while minimizing on rear image glare at the driver's eyes. The control circuit includes a multiple-rate filter for time-averaging an ambient light signal over a shorter time period during increasing ambient light intensities than during decreasing ambient light intensities to simulate the more rapid adaptation of the human eye to increasing light intensities than to decreasing light intensities. The control circuit automatically alters or adjusts the sensitivity of the mirror to rear light based on the ambient light level. The mirror is more sensitive to rear light in relatively low ambient light, such as experienced on rural highways, than in relatively high ambient light, such as is experienced on urban highways. The control circuit calculates ambient light within the driver's field of view. the calculation takes into account the forward light, rear light reflected from the interior rearview mirror, and/or rear light reflected from the windshield, pillars, headliner, and exterior rearview mirrors.

Abstract: The operation of analogue circuit blocks is simulated on a digital computer by a computer program in which each analogue circuit block (Fig. 1-A1-A5; Fig. 3-M1-M4) is represented by a procedure call including details of input signal name(s) (IN1, IN2) amd value(s), output signal name(s) (SIG1-SIG3, OUT) and value(s), the operating parameters for the block and the sampling instant for the evaluation of the or each output signal value. The interconnections between blocks are represented by the use of the same signal names. Each sampling instant indicates when the value of an output signal will have changed by a predetermined amount since the previous sampling instant. A common sampling time is used for the circuit and is selected as the earliest of the sampling instants of the circuit blocks. The simulation can include digital circuit blocks (Fig. 2-L1-L4) represented by an event-driven or a levelised compiled code model, with analogue/digital conversion (Fig. 1-A/D interface I) to handle the interconnections between analogue (A1-A5) and digital circuit blocks (D). A feedback connection (Fig. 4) around part of the analogue circuit (N2, N3 is handles by progressive adjustment of the feedback input signal value while other input signal values (IN2, SIG2, SIG3) are held constant.
