IPC: G06F7/483
Filed: 1990-11-02
Abstract: PURPOSE:To rapidly execute normalizing processing by preparing two priority encoders and simultaneously executing normalizing processing by means of two routes. CONSTITUTION:A priority encoder 4a retrieves bit data '1' fro the upper M bits of mantissa part data MC consisting of N bits and a priority encoder 4b retrieves bit data '1' from the lower (N-M) bits. When the mantissa part data MC whose bit data '1' is retrieved by the encoder 4a and is not retrieved by the encoder 4b are inputted for instance, a long time may be required for the processing of the encoder 4b, so that time required for the rounding processing of a rounding circuit 8 can be shortened. Thereby, time required for normalization and rounding can be shortened as a whole. Thus, normalizing/ rounding processing can rapidly be executed.

Title: Temperature adjusting device
Inventor: WATANABE HIDEKI
IPC: E04F15/18
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To moderate uneven temperature of a supply pipe and a return pipe with a simplified structure by setting an interval between the supply pipe and the return pipe in a delivery region where there are disposed an inlet part and an outlet part to be narrower than than between the supply pipe and the return pipe in a circulation region being a region other than the delivery region. SOLUTION: A supply pipe 14a and a return pipe 14b are disposed through a predetermined distance S1 in first, second, and third circulation regions C, D, and E while in a derivation region where temperature of warm water introduced into the return pipe 14a is high they are disposed such that a distance S2 between the foward pipe 14a and the return pipe 14b is shorter than the distance S1. Accordingly, in the delivation region A temperature difference between the supply pipe 14a where the warm water temperature is high and the return pipe 4b where the warm water becomes low in temperature by radiating heat after circulation can be balanced owing to heat movement between both pipes 14a and 14b, and hence uneven temperature between the adjacent supply pipe 14a and return pipe 14b is moderated.  Particularly, in the respective regions A to E the pipes 14a and 14b form a counter flow to improve heat exchange efficiency.
