摘要:
A coins receiving and dispensing apparatus suitable for food shops or restaurants allows precise transfer and reception of various coins without error and confirmation of the balance of the coin. When coins received from customers are inserted into this apparatus, the coins are immediately sorted by a sorting mechanism with respect to the denominations of the currency and stored at the respective storage portions. When the coins are paid out as change, the coin feeder operates based on a dispensing command signal produced corresponding to the differences between the sold amount inputted in the register and the received amount from the customers to feed the coins of the wanted denomination in the necessary number.

An object is to propose a mold release agent improving the state of a mold surface by repeating casting cycle so as to extend the life of the metal mold actively, and a casting method using the mold release agent. A water-soluble mold release agent applied on a mold surface of a metal mold contains organic acid or organic acid salt which is reducing and ligand, wherein concentration of a total thereof is not less than 0.01 wt % in using concentration and is not more than a fixed concentration which is stability limit of emulsion of the mold release agent in undiluted concentration. Construction weight ratio of the organic acid or organic acid salt which is reducing and the ligand is in the range from 99/1 to 30/70. The mold release agent is applied on a mold surface of a die casting metal mold, molten metal is injected into the metal mold, and the organic acid or organic acid salt which is reducing in the mold release agent is reacted with a component of the mold surface so as to deoxidize Fe2O3 on the mold surface to Fe3O4.

A dampening water composition for lithographic printing which comprises 0.1 to 5% by weight of at least one member selected from the group consisting of monoalcohols or diols of alkanes or alkenes having 5 to 11 carbon atoms, to which 1 to 10 moles of ethylene oxide and/or propylene oxide are added. The dampening water composition is not toxic, has not a possiblity of causing a fire and pollution of working atmosphere and, therefore, the use of a local exhaust installation is not necessary. Moreover, it is excellent in characteristics as dampening water such that it does not cause contamination of metering roll, has good bleeding properties, emulsifying properties and stability in continuous processing as well as low foaming properties. Thus, the composition makes printing operation quite stable.
