Abstract:
Provided are a spiral type membrane element that can re-collect the electric power that is used in a good manner, and a spiral type membrane filtering device having the same. The spiral type membrane element comprises a power generating section that generates electric power by using a liquid, and an electric power outputting section that outputs, either in a wired manner or in a wireless manner, the electric power supplied from said power generating section. The electric power that is generated in the power generating section using the liquid (raw water, permeated water, or concentrated water) can be output from the electric power outputting section in a wired manner or in a wireless manner. Therefore, the electric power that is output from the aforesaid electric power outputting section can be used in an electric component disposed outside or can be stored into a capacitor section disposed outside.

Abstract:
To provide a method for manufacturing a piezoelectric resonator which can widen the range of frequency adjustment while saving metal thereby suppressing reduction of the yields when forming a metal film for frequency adjustment at the tip of an vibrating arm. The method of manufacturing the piezoelectric resonator according to the present invention includes the steps of: bringing a substrate in which an outside shape of a piezoelectric oscillating piece is formed, into contact with an etching solution; forming grooves in a plurality of vibrating arms using a mask having an aperture at the portion corresponding to the groove, and having a metal film formed on the whole surface except the aperture; and thereafter, forming a resist mask on the surface of the substrate so that resist is left at the tip of the vibrating arms which will be a formation area of a metal film for frequency adjustment so as to remove the metal film by etching. Then, forming an electrode film after peeling off the resist film left at the tip of the vibrating arm.
