Title: Distillation purifying method
Inventor: YANAI ISAMU
IPC: C07C49/08
Filed: 2002-01-30
Abstract: <P>PROBLEM TO BE SOLVED: To reduce a cost and to obtain a component B of high purity in a distillation purifying method wherein raw material containing four components A, B, C, D whose boiling point goes higher in alphabetical order, while the components A, C being less than B, D, is distilled to four cuts, whose middle cut is rich in the component B.  <P>SOLUTION: The raw material is supplied to a first compartment of a common distillation tower, the inside of which is divided with a vertical partition wall, and a light cut containing the concentrated component A is distilled out. Then in the intermediate room, vapor being rich in the components B, C, and liquid being rich in the component D is separated and supplied respectively to a third, second, and fourth compartment. A middle cut containing the concentrated component B in the third compartment and a heavy cut containing the concentrated component D in the second compartment are each distilled out, while a semi-heavy cut containing the concentrated component C is distilled out of the fourth compartment. Thus each component is distilled out to obtain the component B of high purity. And in this case, the heat consumption in the distillation can be reduced because reflux capacity can be reduced.  <P>COPYRIGHT: (C)2003,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a game machine which can determine whether an abnormal state of putting out prize balls is caused by noise intruding into a line or by individual differences in a main board and a put-out control board, and which can take measures without suspending the put-out of the prize balls, when the state of putting out the prize balls is made abnormal.  <P>SOLUTION: In the case where the counting of the prize balls is performed by both the main board 100 and the put-out control board 200 in accordance with a detection signal from a prize-ball put-out sensor, it is determined that the main board 100 has not finished the counting yet when the control board 200 finishes the put-out of the prize balls (S148: No); and when it is determined that a predetermined time has elapsed (S150: Yes), '1' is added to a deceleration counter for determining the magnitude of deceleration of a prize-ball put-out motor. Thus, a prize-ball put-out speed is reduced, time for detection of the prize ball by the prize-ball put-out sensor is made longer, and the detection signal is stabilized, so that miscounting caused by the individual difference can be eliminated.  <P>COPYRIGHT: (C)2003,JPO
