Title: Shift and rounding circuit
Inventor: RUBII BEIIROO RII
IPC: G06F5/01
Filed: 1994-11-29
Abstract: PURPOSE: To reduce the accumulation of rounding errors in a series of arithmetic operations by rounding the result of division by a power of 2. CONSTITUTION: Words X=XN-1, XN-2ψ, X0 applied from an input terminal 111 in the figure are right-shifted by (m) bits by shift registers (realized by multiplexing circuits 101-105 here) so that division results Y=YN-1, YN-2,..., Y0 (X0 and Y0 are the least significant bits) by 2m of X can be obtained. Then, a rounding processing is operated by adopting the result of the logical sum (Xm OR Xm-1 OR Xm-2 OR...OR X0) of a valve Xm obtained by simply operating the right shift by the (m) bits by using the least significant bit of the divided result which is 0, and values Xm-1, Xm-2...X0 dropped from the least significant bit by the right shift.

IPC: F16F9/46
Filed: 1989-12-08
Abstract: PURPOSE:To aim at a long lifetime and simplified structure of an actuator by using a light receiver/projector for detecting the rotational position of a motor, and disposing a light reflecting plate on the rotational circumferential side of a plant gear reduction mechanism opposite to the light receiver/projector. CONSTITUTION:Inside a case 1, a flat motor 2 is fixed by a jam pin 3, and the output shaft 4 of the flat motor 2 is connected to a plant gear reduction mechanism 5. Upon switching a mode, the flat motor 2 is rotated, and the speed of the rotation is reduced by the planet gear reduction mechanism 5 and the rotation is transmitted to a control rod connected to the output shaft 4. This rotational positioning is performed by a light reflecting plate 11 and a light receiver/projector 14 disposed opposite to the plate 11. The light receiver/ projector 14 after detecting the stop position of the flat motor 2 generates a stop signal. The use of the light receiver/projector 14 can eliminate a mechanical contact portion, and further the disposition of the light receiver/projector 14 opposite to the light reflecting plate 11 realizes a long lifetime of an actuator and simplification of its structure.

Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a separation system which improves the separation efficiency of an aluminum separator (maintenance of separation purity, improvement of treatment capacity) without enlarging equipment on the side of the aluminum separator even when the mixing ratio of plastic bottles is high and an amount to be separation-treated is large.
