Abstract:
A protein designated "Lg-Flo1" can be produced recombinantly and confers brewer's yeast-type flocculating property, for example, when Lg-FLO1 DNA is expressed in non-flocculent yeast strain. Conversely, a flocculent yeast strain can be rendered non-flocculent by eliminating or disrupting the ability of the strain to express Lg-Flo1.

Abstract:
A coin separator having a first coin passage along which coins are guided, a coin detector disposed in the first coin passage for discriminating whether coins passing therethrough are true or false and to which group belong coins which are discriminated as true and outputting a signal relative to whether the coins are true or false and a group signal indicative of the group to which the discriminated coins belong, a true coin passage and a false coin passage each connected to the first coin passage, a first dividing mechanism for introducing the coins passing through the first coin passage into either the true coin passage or the false coin passage in response to the signal outputted from the coin detector, a plurality of second coin passages connected to the true coin passage, a second dividing mechanism for introducing the coins passed through the true coin passage into one of the plurality of second coin passages in response to the group signal outputted from the coin detector, and a third dividing mechanism for dividing the coins passed through each of the second coin passages into a plurality of groups with the third dividing mechanism being provided in each of the plurality of second coin passages.
Abstract:
A money discriminating apparatus comprising a bill transporting path defined between a pair of spaced, but opposed wall surfaces. A coin transporting path is defined by a groove formed in at least one of the wall surfaces. The groove has a width slightly larger than a diameter of a largest one of coins to be transported and a depth slightly larger than a thickness of a thickest one of the coins. Inlet and outlet of coin transporting path open respectively to inlet and outlet of the bill transporting path. A transporting system transports bill and coin along their respective paths. A discriminating unit discriminates authenticity and kind of bill and coin in course of being transported along their respective paths. Preferably, the transporting system comprises a pair of transporting belts and mating surfaces arranged in facing relation respectively to running surfaces of the respective belts. The running surfaces of the respective belts cooperate respectively with the mating surfaces to transport money while clamping the money therebetween.
Abstract:
In an electronic conversion circuit for converting an analog value to digital codes or digital codes to an analog value, the circuit comprises at least two conversion hold blocks. Each of the analog processing units has two functions, that is, one function is to perform sampling of the analog value and to circularly convert the analog value to an output analog value in order to obtain a digital value based on the output analog value, and the other function is to sequentially input digital codes and to convert digital codes in order to obtain the analog value.
Abstract:
The control system is constituted by a plurality of switches operated by inserted coins of different denominations, first register for storing amounts of inserted coins for each denomination and a second register for storing remaining amount of change. The amount of coins corresponding to operated switch is added to the content of the first register, 1 is added to the content of the second register in accordance with the denomination of the inserted coin, and 1 is substracted from the content of the second register in accordance with the denomination of payed out money. The selling price of a merchandise is subtracted from the total price of the inserted coins for calculating the amount of change. Selling is possible or not is determined by sequentially subtracting the price of the coins starting from a coin of the highest price from the change. The content of the first register is sequentially changed until the content exceeds the selling price and the selling price is subtracted from the content of the first register for setting the content to the amount of change for different denomination of coins.
Abstract:
This bill accepting device comprises a bill discrimination section for discriminating whether an inserted bill is true or not, an escrow section capable of retaining a bill accepted by the bill discrimination section as a true bill and returning the retained bill, a stocker section for storing the bill accepted by the bill discrimination section as a true bill, and passage switching means for causing a bill passage in the bill discrimination section to communicate selectively either with the escrow section or with the stocker section. The passage switching section normally communicates the bill discrimination section with the escrow section to enable an inserted bill to be retained in the escrow section in a state in which the bill can be readily returned. When the escrow section has become full, the passage is switched so that the inserted bill is guided from the bill discrimination section to the stocker section.
