摘要:
A methane separation method of the present invention at least includes: mixing the biogas and an absorbing liquid that absorbs carbon dioxide in a mixer so as to form a mixed fluid of a gas-liquid mixed phase; introducing the mixed fluid into a first gas/liquid separator so as to separate the mixed fluid through gas/liquid separation into methane and a CO2-absorbed liquid formed due to an absorption of the carbon dioxide by the absorbing liquid; recovering methane separated in the first gas/liquid separator; and supplying the CO2-absorbed liquid through a supply port of a membrane module comprised of a container and a plurality of hollow fiber permeable membranes built therein to inside of the membranes so as to make the CO2-absorbed liquid permeate the permeable membranes, and lowering a pressure outside the permeable membranes to a level lower than that inside the permeable membranes.

The present invention provides a effective recycling method for a fiber fabrication layer unit which has been separated and retrieved from a tile carpet and which comprising a fiber assembled layer to which a part of a backing layer being integrally contacted and also provide a method for producing a product to be recycled. And the method for effectively recycling the fiber fabrication layer unit comprises the steps of; applying a pressured shearing force to a surface of a backing layer of a tile carpet collected from the market before it is broken, so that at least a part of the backing layer is separated from a fiber assembled layer or from a rest of portion of the backing layer; separating the backing layer and the fiber fabrication layer unit including the fiber assembled layer from the tile carpet from each other; after that, gathering and connecting the tile carpets or the fiber fabrication layer units to each other with utilizing heat energy or suitable adhesive, to form a tile shaped block like sheet material or a longitudinal sheet material; and forming various kinds of industrial materials from these sheets.
摘要:
A digital key telephone system which is connected to a digital network via a digital channel, a transmission error which has occurred on the digital channel is detected, and upon detection of the transmission error, information representing the transmission error is stored in an error table. When a display request of a transmission error is input from a digital key telephone, error information stored in the error table is read out, the readout information is transferred to the digital key telephone, and the information is displayed on a display of the telephone.

A communication switching system is disclosed which includes a plurality of telephone sets and data terminals connected to an exchange. The data terminals have corresponding telephone sets. Other telephone sets operate independently. Information regarding the correspondence of the data terminals to the telephone sets is stored in the exchange. The telephone sets related to the data terminals initiate connection through the exchange of one data terminal to another data terminal. The telephone sets control the connection by the exchange using a two key sequence. The exchange controls the connection in accordance with data terminal/telephone set corresondence data stored in the exchange.
摘要:
In a key telephone system connectable to both ISDN and PSTN, for the purpose of compensation of a difference in speech signal level between ISDN and PSTN, digital pads are incorporated in an ISDN interface unit mounted on a key service unit of this system. In the digital pads, original PCM-code speech signals received/transmitted from/to the ISDN line are converted into PCM-code speech signal with a compensated speech signal level obtained by adding a selected gain to the original speech signal level. Since the difference in the speech signal level between ISDN and PSTN differs according to the conditions, an appropriate gain is selected from a plurality of previously prepared gains. That is, the relationship between telephone numbers and information signals indicative of the selected gain is registered in the key service unit. Therefore, when conversation is made to a subscriber whose telephone number has been registered through the ISDN, a gain registered in correspondence to the subscriber's telephone number can be selected automatically.

摘要:
A problem that the present invention is to solve is to provide: a main body of a peptide molecule which is effective for inhibition of various maladies such as osteoporosis, osteoarthritis and pressure ulcer, particularly, a dipeptide which is easy to absorb into a body in an intestine; a collagen peptide which comprises the dipeptide as an essential dipeptide; and a malady inhibitor which comprises the dipeptide as an essential effective component. As a means of solving such a problem, a collagen peptide according to the present invention is characterized by comprising a dipeptide having a structure of Hyp-Gly as an essential dipeptide. A dipeptide according to the present invention is characterized by having a structure of Hyp-Gly. A malady inhibitor according to the present invention is characterized by comprising a dipeptide having a structure of Hyp-Gly as an essential effective component.
