Title: Developing device
Inventor: MENJO TAKESHI
IPC: G03G15/08
Filed: 1987-01-19
Abstract: PURPOSE:To stably control developer concentration by providing a variation curve part to a toner replenishing table which determines the replenishing quantity of toner according to the detection signal of developer concentration. CONSTITUTION:A developer concentration signal D is compared with a value D0 (standard developer signal) when a developer has standard concentration and toner replenishing control is so performed that toner is not supplied when D>=D0 and supplied when D<D0. Namely, the toner replenishing table is so set that the replenished amount of toner is small in an area where the difference signal (d) is small and large in an area where the difference signal (d) is large. Thus, the toner replenishing table which determines the supply amount of toner has the variation curve part, so the invariably stable toner supply control is performed according to an original regardless of whether toner consumption is large or small.

Abstract: PURPOSE:To suppress any unnecessary signal removing response with the reception level below the threshold, by determining the elevation of an aircraft from altitude information in an airplane code pulse signal received and encoded and distance information from measurement to determine the threshold corresponding to the gain difference of an antenna. CONSTITUTION:The antenna pattern of an antenna 1 is such a radiation pattern that the gain at the lower elevation to reduce the effect of the reflection from the ground while the gain at the upper elevation is raised to make the airplane easy to spot at a low elevation in a long range. A threshold is provided for a signal detection circuit 3 and the sensitivity of the reception level is changed according to the distance of the airplane to detect a signal. In this case, to meet the requirement of detecting all available airplanes, depending on the elevation, the detection sensitivity more than necessary is possessed to lower the effect of suppressing unnecessary signals. The altitude of a specified airplane is determined from the output of a response processing circuit 4 while the threshold of a removing circuit 5 is set from the gain varying characteristic with respect to the elevation of the antenna 1 to remove unnecessary response signals. This enables the suppression of unwanted reception such as that from an antenna side lobe.

Abstract: PURPOSE:To decrease the number of hardware parts and to increase computing speed by providing an (n+1)-digit adder in the division having an n-digit exponent part and performing the arithmetic operation of the exponent part with a single adder and a single arithmetic process. CONSTITUTION:At one of two input pats of an adder 10, a coefficient Xn-1 of the (n-1)-th digit is inputted to an n-th digit input part. At the same time, the coefficient Xn-1 is inverted by an inverter I and inputted to an (n-1)-th digit input part.

At the other input part of the adder 10, the n-th digit coefficient 1 is inputted to an N-th digit input part. Then the (n-1)-th to 0th digit coefficients Yn-1-Y0 are inputted to the (n-1)-th to 0th digit input parts respectively via the inverter I. Thus just a single adder can perform the arithmetic operation of an exponent X-Y+B. As a result, the hardware quantity is reduced and the computing time is shortened.
