A filter device comprises a substrate having a top surface and a bottom surface, and at least one acoustic wave situated on the top surface of the substrate, wherein the bottom surface of the substrate is roughened to reduce the reflection of an acoustic wave back to the acoustic wave filter. The effect achieved by the roughening of the bottom surface of the substrate that an acoustic wave which is generated by the acoustic wave filter and reaches the bottom surface of the substrate, is basically scattered so the acoustic wave that is actually reflected back to the acoustic wave device is reduced which, in turn, improves the performance characteristics of the acoustic wave filter.

A mobile terminal includes a metal frame including a base portion and an edge portion formed along the outer edge of the base portion, first and second cases bonded to the front and back sides of the metal frame so as to expose the edge portion to the outside, first and second waterproof layers formed between the cases and the metal frame, conductive members that operate a radiator for antennas, together with the edge portion, and are formed on one side of the second case, and feeding portions for feeding the conductive members, the feeding portions being disposed in an enclosed space formed by the waterproof layers.

The fertilizer of the invention is a fertilizer containing a sparingly water-soluble phosphatic fertilizer and a urea / aliphatic aldehyde condensation product. The process for controlling inoganizing speed of urea / aliphatic aldehyde condensation product of the invention comprises adding to the urea / aliphatic aldehyde condensation product a sparingly water-soluble phosphatic fertilizer having special elution characteristics. The fertilizer of the invention and the process for controlling inoganizing speed of urea / aliphatic aldehyde condensation product of the invention make it possible to control the inorganizing speed of the condensation product without changing the particle size or form, that is, to control development of the efficacy of the condensation product used as a fertilizer. The fertilizers of the invention or the urea / aliphatic aldehyde condensation products whose inorganizing speeds are controlled according to the process for controlling the inorganizing speed of the invention can provide nitrogen components to plant in accordance with the periods of culture of desired crops and a pattern of absorbing nutrition. This is effective in saving of the number of additional fertilization or nitrogen components left in soil after the period of culture.

A solenoid valve 10 including a valve sleeve 41, and a solenoid portion 20 which is mounted at one end along axial direction of the valve sleeve 41. A plurality of ports 51 to 54 are formed on the valve sleeve 41. In at least an outlet port 51 of the plurality of ports, a relation of S1≧S0 is fulfilled, where S1 is an opening area of valve portion when the spool 60 moves in an axial direction to maximally open the valve portion between the outlet port 51 and the internal flow passage 47, and S0 is the total flow passage cross-sectional area.

An electrode catheter that includes an elongate electrode catheter body having a distal end and a proximal end, at least one electrode pole in the area of the distal end of the electrode body, and at least one supply line, which runs insulated in the electrode body in the main direction (H) from the proximal end to the distal end, to the at least one electrode pole, wherein the at least one supply line is configured to desensitize the electrode catheter to the radiation of an electromagnetic field of an interfering frequency having a specific wavelength(λ), with the supply line changing its run direction at least twice in such a way that it runs at least once opposite to the main direction (H), the distance (L1,L2) between two direction changes (R) is shorter than half of the wavelength (λ / 2) of the interfering frequency.
