摘要:
An objective of the present invention is to provide a composition for dyeing dental plaque for evaluation of dental caries activity that is capable of simultaneously dyeing dental plaque and evaluating dental caries activity, and which can evaluate thick dental plaque more accurately than the conventional technique. The composition for dyeing dental plaque for evaluation dental caries activity comprises: a blue pigment being dissolved in water and having a color tone not changing at pH 7 or less; a red pigment being dissolved in water at pH more than 4.5 but not dissolved in water at pH 4.5 or less, and having a color tone not changing at pH 4.5 or less; and sugar. The content of sugar is preferably 1 to 50 weight parts to the total of 1 weight part of contents of the blue pigment and the red pigment, and ratio of contents of the blue pigment and the red pigment is preferably 1:3 to 3:1.

An electronic device according to the present invention includes: display screens capable of displaying information thereon; touch panels which are provided on these display screens and are adapted to be manipulated by a user; touch-panel determination portions which are electrically connected to the touch panels and are adapted to receive coordinate information from the touch panels due to user's manipulations thereof; and a controller which is electrically connected to the display screens and to the touch-panel determination portions, and is adapted to cause the display screens to display information thereon and to receive signals inputted thereto from the touch-panel determination portions, wherein the controller includes a displayer, which is adapted to cause the display screens to display information thereon, and when the touch-panel determination portions receive coordinate information, to display information about a peripheral area including the coordinates thereon, at a position different from that of these coordinates.
摘要:
A cooling system that cools hot rolled long steel bar, provided with a plurality of chambers that are arranged along the longitudinal direction of the rolled steel bar. Each of the plurality of chambers is provided with a blow outlet that, facing from the chamber to the rolled steel bar, blows out compressed air for cooling that is introduced to the chamber from a gas inlet that is connected to the chamber; a nozzle plate having a plurality of nozzle holes that is provided at this blow outlet so as to face the rolled steel bar; a cooling water supply nozzle that supplies cooling water into the chamber; and a rectifying plate that is provided between the gas inlet and the cooling water supply nozzle, and that prevents the compressed gas for cooling that is introduced from the gas inlet from directly striking the nozzle plate. The cooling system of the present invention sprays a cooling medium that is produced by mixing the cooling water that is supplied from the cooling water supply nozzle and the compressed gas for cooling that is introduced from the gas inlet and rectified by the rectifying plate toward the rolled steel bar through the nozzle holes of the nozzle plate, and performs uniform cooling of the surfaces of the rolled steel bar.
摘要:
When a closed loop transmission diversity control is performed by controlling the phase of the transmission signals from the plurality of antennas according to feedback information noticed by the mobile station to transmit the signals, an antenna verification on-off control unit 370 controls the on-off of an antenna verification process of estimating the phase of the transmission signals from the plurality of antennas according to the information about the channel of the signals transmitted in the uplink from the mobile station to a radio base station. Thus, depending on the channel type (for example, a packet channel, a voice channel, etc.), the on-off control is performed on the antenna verification process, thereby performing easier and more appropriate control and improving the quality of a channel.
摘要:
The present invention relates to an antistress agent comprising as an active ingredient a saccharide containing 3-O-α-D-glucopyranosyl-D-glucose as a structural unit. It is an object of the present invention to provide said antistress agent which is free from side effects as a medicine, and can be taken habitually and also can be ingested simply as a food or a beverage, or the like.
摘要:
Sounds in different frequency range are generated from the rear, top and/or front face of the musical tone apparatus, sounds are generated and spread in all directions around the musical tone apparatus, and the tones sound very realistically acoustic. Vibration of the sound board does not resonate, tones generated from the sound board are not changed unintentionally, and tones of real acoustic musical instruments are realized. Vibration from the sound board is not directly transferred to the whole musical tone apparatus, by means of not allowing the sound board to touch the body of the musical tone apparatus and of pressing and fixing the soundboard to the attachment component with the thickness of the attachment component compressed.
