Title: Motion detector for moving image coder
Inventor: WATANABE HIDEAKI
IPC: H04N19/423
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale without deteriorating the accuracy of retrieval by providing two computing element groups, dividing picture elements of one peripheral block retrieved by the 1st computing element group into plural numbers and using the 2nd computing element group to make calculation for plural number of times thereby retrieving a block with a minimum difference. SOLUTION: When picture element strings By to By+x with a minimum difference are obtained by a 1st stage retrieval, peripheral picture element strings including the retrieved picture element strings are obtained as picture element strings C. In the 2nd stage, the number of computing elements used for difference calculation per one picture element is p and the arithmetic precision is enhanced by a multiple of p for the strings A, C as  p×(n-m)bits}. In this case, since number of picture elements for difference calculation is decreased to 1/p, p times of calculation is required to obtain differences for (x+1) picture elements. Thus, the calculation result of each time is sequentially accumulated by using an adder 4 and a memory 7 and the final result is obtained after the arithmetic operation of p times. Thus, the retrieval error is reduced while using the computing elements in common for 1st and 2nd stages.

Abstract: PURPOSE:To lower pool surface temperature and to reduce the inner pressure of a nuclear reactor containment vessel at a loss of coolant accident LOCA by providing a coolant return pipe connecting a pressure vessel to a suppression pool, and by supplying a coolant in the suppression pool, to the pressure vessel. CONSTITUTION:At a LOCA, steam discharged to a drywell 2 from a pressure vessel 1, is introduced to a suppression pool 4 through a vent tube to be condensed there and the water level in a pressure suppression chamber 3 rises. On the other hand, from the relation-ship between free water levels in the pressure vessel 1 and the vent tube 5, influenced by the release of an automatic pressure reducing valve 6, a coolant increment in the pressure suppression chamber 3 is injected into the pressure vessel 1 by gravity force. In this occasion, high temperature water which is brought in from a water intake 10 placed at the upper part of the suppression pool 4, passes through the low temperatured bottom part of the pool via a return pipe 8, and therefore water temperature at the pool bottom rises. By this process, the suppression pool is mixed enough and the surface temperature of the pool is lowered, and consequently the inner pressure of the nuclear reactor pressure vessel at the LOCA can be lowered.

A fraction of the magnetic flux intersects the winding 10 of the stationary section to induce a voltage which is in turn inputted into a reproduction amplifier. Herein, there is provided a stepped portion A on opposed surfaces of rotary and stationary section magnetic cores 7 and 8 with the consideration of the influence of the generated magnetic flux on the adjacent windings. By this stepped portion, magnetic reluctance between the adjacent windings of the rotary and stationary sections is increased.
