Abstract: There is provided a coupon issue system and the like capable of issuing an attractive coupon to a turn-waiting visitor. When accepting new registration and receiving a request to issue a coupon from a management server 300, a coupon issue server 400 selects a coupon to be issued, based on new registration information and the like transmitted from the management server 300. The new registration information includes the number of persons for the reservation and a seat type, estimated waiting time and the like. The coupon issue server 400 transmits the selected coupon to a turn management terminal 100 of a corresponding store as coupon information. The coupon information received by the turn management terminal 100 is outputted by the printer 200 as a coupon.

Abstract: In a turn management system (1000), whether or not input to an input device (115) is not performed for a predetermined period of time is determined, and a standby screen is displayed when it is determined that the input to the input device (115) is not performed for the predetermined period of time. At the time, a first standby screen is displayed when there is turn waiting in a waiting list, and a second standby screen is displayed when there is no turn waiting in the waiting list. Thus, unneeded issuance of a numbered ticket can be suppressed, and operation interruptions of a worker or the like can be reduced.

Abstract: By a scroll operation, at a lower part of a waiting list L1, customers of reception numbers “9”-“11” not displayed in FIG. 4A are displayed. At an upper part of the waiting list L1, an arousing alert AT1 (“there are customers waiting above” or the like) is displayed such that it is recognized that there are customers (specifically, the customers of reception numbers “1”-“3”) who are hidden outside the screen and are invisible.

Abstract: Disclosed herein is a novel compound which is excellent in solubility to water around a neutral range, stable in an aqueous solution state for a long period of time, and high in coloring sensitivity with a stable coloring development, and is represented by the general formula (I): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which may be the same as or different from one another, represent lower alkyl groups, and X.sub.1 and X.sub.2 both represent --O(CH.sub.2).sub.n SO.sub.3 M in which M is a hydrogen atom, an alkali metal ion or NH.sub.4.sup.+, and n is an integer of 2-4, or either of X.sub.1 and X.sub.2 represents --O(CH.sub.2).sub.n SO.sub.3 M in which M and n are the same meanings as given above and the other represents a hydrogen atom. This reagent is hardly susceptible of the influence of the serum components such as hemoglobin, bilirubin and so on due to its color having absorption on a longer wavelength side.

Abstract: A water-soluble cross-linked polymer of the enzyme lysyl endopeptidase produced by Achromobacter lyticus and a process for preparing the polymer as well as a semi-synthesis of human insulin using the polymer.
