摘要:
There is provided a method of controlling a tape processing apparatus where braille is embossed at one side in the width direction of a tape with an embossing unit arranged at the one side. The method includes: an embossing-position defining step of defining a braille embossing position in the width direction of the tape; an embossing-data generating step of generating embossing data based on input information and the embossing position; and a braille embossing step of embossing braille on the tape based on the generated embossing data. In the embossing-data generating step, when the embossing position is arranged at one side in the width direction on the same side as the embossing unit, the embossing data is generated for forward embossing. While, when the embossing position is arranged at the other side in the width direction opposite to the embossing unit, the embossing data is generated for reverse embossing.

An electric-powered tool comprises: a housing; and a brush motor contained in the housing, having: brush holders, each of brush holders holding a carbon brush; and brush terminals, made of an electrical conductive and elastic material having at least one blade portion, a palm portion, and an arm portion, for providing electrical connection thereof to the brushes through the brush holder by catching and griping the brush holder by the blade and the palm portions, the arm portion extending from the palm portion to an end where a fixing portion is provided, each of the brush terminals being fixed by the fixing portion with a positional offset to develop a contact pressure between the palm portion and the brush holder. Further, the arm portion is further extending over the fixing portion to form a connecting portion. On the other hand, one end of a field coil is connected to a connector. Thus, the brush holder is connected to the field coil through the connection portion and the connector.

An embossing control method used in a braille-embossing apparatus includes an embossing head that embosses a braille string on a tape fed along a tape-conveying path, the braille string being embossed in an area biased to one of upper and lower sides of the tape along the width of the tape without changing the upper and lower direction of the braille string. The embossing control method includes the steps of designating the area biased to one of the upper and lower sides of the tape along the width of the tape as a braille-embossing area in which braille embossing is to be performed and embossing the braille string in the designated braille-embossing area.

An electroconductive paste for forming an electric circuit which is low in resistivity, high in electroconductivity and minimized in change of resistivity even after a thermal shock test and/or a humidity and DC applied test, can be obtained by using a composite electroconductive powder comprising a flake-like electroconductive powder made of a material such as silver, a silver alloy, a silver-coated copper powder or a silver-coated copper alloy powder and an unsteady-shaped electroconductive powder such as a reduced silver powder. Also, by using a composite electroconductive powder comprising an electroconductive powder having an aspect ratio of 6 or greater and an electroconductive powder having an aspect ratio of 5 or less, there can be obtained an electroconductive paste which is low in resistivity, high in electroconductivity, minimized in change of resistivity even after a thermal shock test and/or a humidity and DC applied test, and capable of improving probability of contact between the electroconductive powder particles, elevating electroconductivity of the electric circuit, and also raising electroconductivity especially when a circuit is printed on a sheet-like substrate and the printed circuit is pressed. The electric circuit formed on the surface of a substrate by using such an electroconductive paste is low in resistivity, high in electroconductivity and also excellent in migration resistance.

A disclosed molecular communication system includes a molecular transmitter configured to transmit an information molecule in which prescribed information is encoded, a molecular receiver configured to receive the information molecule, and a molecular capsule configured to carry the information molecule from the molecular transmitter to the molecular receiver. Each of the molecular transmitter, the molecular receiver, and the molecular capsule has an artificial cell membrane in which at least one kind of molecular switch is embedded, the molecular switch being responsive to an external input signal so as to control association and separation between the molecular transmitter and the molecular capsule, and association and separation between the molecular capsule and the molecular receiver, upon application of the external input signal.
