Abstract:
A wireless power feeding system capable of long distance and highly efficient space transmission of power is provided. A wireless power feeding system includes a power transmitter, a power receiver, and a power receiving body. The power transmitter generates electromagnetic waves. The power receiver is supplied with power by means of the electromagnetic waves received from the power transmitter using a magnetic field resonance phenomenon. The power receiving body is inserted into an electromagnetic field created by the power transmitter and the power receiver, and receives power by means of the electromagnetic field.
Abstract:
A channel (1) formed in a substrate (41) branches into channels (2, 3) at a branch point (43). On this branch point, obstacles (8) having a columnar structure are aligned at certain intervals.
Abstract:
A fragmenting reaction of peptide is achieved while maintaining the isolated state of peptide. Isolated peptide fractions isolated by electrophoresis are prepared in flow paths. Subsequently, prepared peptide fractions are dried by each of the flow paths. Then, dried peptide fractions are in contact with protease. Then, independent liquid membranes of a solvent are formed over the surfaces of peptide fractions, which have been in contact with protease, disposed on the flow paths, respectively.
Abstract:
After a sample is previously separated into plural components in a channel formed in a microchip (353), the channel is irradiated along a separation direction with a laser beam from a laser oscillator (361) to sequentially ionize each fraction separated in the channel. The ionized fraction is detected by a mass spectrometry unit (363) and analyzed by an analytical result analyzing unit (371). The analytical result is stored in a memory (369) while associated with position information in a driver control unit (367) and information on laser beam irradiation condition in a laser control unit (373), and the analytical result is imaged by an imaging unit (375). The imaged analytical result is displayed on a display (377).
Abstract:
Disclosed is a donepezil-containing transdermally absorbable preparation which develops reduced adverse side effects and shows a satisfactory level of therapeutic effect. The preparation comprises an adhesive and a donepezil component (containing crystalline donepezil having type-B crystal polymorphism) and/or a salt thereof, wherein the donepezil component or the salt thereof is contained in an amount of 9 to 50% by mass relative to the total weight of the adhesive. The preparation (particularly, one having a non-aqueous adhesive layer) shows an excellent penetration of donepezil and/or a salt thereof into the skin, retains good stability of the active ingredient therein, and is remarkably reduced in local stimulation and adverse side effects.
Abstract:
A liquid sample (104) introduced in a main flow passage (101) is held in a dam portion (105), and a trigger liquid (106) is filled in a trigger flow passage (102). In this state, the trigger liquid (106) is further introduced at desired timing into the trigger flow passage (102) so that the front end portion of the level of the trigger liquid (106) is advanced and the front end portion is brought to be into contact with the dam portion (105). This causes the liquid sample (104) to move to the right (downstream side) in the figure, resulting in the liquid sample (104) flowing out to the downstream side of the main flow passage (101). This means that the trigger liquid (106) provides priming to realize a liquid switch.
Abstract:
A channel (103) is formed in a substrate (101) and a drying area (107) comprising a plurality of pillars (105) is formed in one end of the channel (103). A cover (109) is formed over the channel (103), except the area above the drying area (107). When a sample is introduced into the channel (103), it is guided to the drying area (107) by capillary phenomenon. The drying area (107) is heated by a heater (111) to evaporate the solvent for concentrating and drying the solute.
Abstract:
A sample which contains protein is stably maintained in a liquid state during electrophoresis. Electrophoresis chip 1 includes substrate 2, channels 5a to 5d which is provided on surface 3 of substrate 2 and which has openings 4a to 4d at the top thereof, wherein a sample solvent is adapted to be supplied to the channel, and evaporation inhibitor reservoirs 8a, 8b for storing an evaporation inhibitor for the sample solvent, the reservoir being provided independently of channel 5a to 5d and being spatially connected to opening 4a to 4d of channel 5a to 5d.
Abstract:
A chip 400 is composed of a substrate 401, and a frame component 402 provided on the surface of the substrate 401, so as to be brought into contact with the substrate 401. A flow path 102 which retains a liquid sample, and serves as a trench-type flow path allowing therethrough electrophoretic migration of a sample to be subjected to mass analysis, is configured to use the substrate 401 as the bottom surface, and to use the frame component 402 as the sidewall. The substrate 401 and the frame component 402 are configured to be separable.
Abstract:
The present invention provides a technique for precisely controlling the lyophilic/lyophobic property of a material surface using a simple construction, a method of utilizing this technique to make anisotropic the level of lyophilic or lyophobic property of a material surface having its lyophilic/lyophobic property controlled, and a method of applying the technique to retain a liquid in a predetermined region of the material surface. For example, liquid retaining portion 103 consists of a regular recess and protrusion structure, and flat part 104 consists of a flat surface surrounding the outer periphery of liquid retaining portion 103 are formed on a surface of substrate 101. The recess and protrusion structure is formed so that the surface area of recess and protrusion structure of liquid retaining portion 103 is larger than the area of the region in which liquid retaining portion 103 is formed and so that the multiplication factor of the surface area has a desired value.
