A juice extractor capable of extracting juice from vegetables, fruits or soymilk from beans is disclosed. The extractor includes a housing having a draff outlet port and a juice outlet port, a screw having an upper rotary shaft inserted in a rotary shaft hole of the housing and a lower rotary shaft with a plurality of screw spirals formed on an outer periphery thereof, and a mesh drum for extracting the juice toward the juice outlet port, and a rotary brush mounted between the housing and the mesh drum and having a brush holder.

A piezoelectric resonator of the present invention is structured such that on a substrate 5 having a cavity 4 formed therein, a lower electrode 3, a piezoelectric body 1, a spurious component control layer 16, and an upper electrode 2 are formed in this order from bottom up. The spurious component control layer 16 is a layer for controlling a spurious frequency, and composed of, for example, a metallic material, a dielectric material, or a piezo electric material. By additionally providing the spurious component control layer 16, it is made possible to cause variation of the spurious frequency due to unwanted variation to become greater than variation in resonance frequency of the main resonance of the piezoelectric resonator. Thus, it is possible to realize a piezoelectric resonator having an admittance frequency response where no spurious component occurs between resonance frequency fr and antiresonance frequency fa.

In a first aspect, the present invention provides a motor, fan and filter arrangement for a vacuum cleaner, comprising: a motor (10); a fan (20) connected to an output shaft (12) of the motor and having an axial intake; and a filter (30, 230, 330); wherein the fan (20) is arranged with its axial intake facing the motor (10); and the motor (10) is housed within the filter (30, 230, 330).
