摘要： Disclosed herein is a piezoelectric motor. The piezoelectric motor includes a piezoelectric vibrating body, a dummy piezoelectric sheet layer and a contact member. The piezoelectric vibrating body is configured such that piezoelectric sheets on which electrode patterns are printed are stacked on one on another. The dummy piezoelectric sheet layer is provided on the piezoelectric vibrating body. The contact member is provided on the outer surface of the dummy piezoelectric sheet layer. The contact member transmits vibrations generated from the piezoelectric vibrating body to the outside. Therefore, the piezoelectric motor can minimize a problem in which vibration characteristics vary attributable to contact between a contact member and an electrode pattern of a piezoelectric vibrating body.

摘要： The present invention is related to a method of fabricating a rigid-flexible printed circuit board. Specifically, this invention relates to a method of fabricating a rigid-flexible printed circuit board, in which an internal circuit pattern exposed for use in an external pad and a mounting pad is protected from external environments using a resist cover by window etching the base copper foil of a flexible region upon formation of an external circuit pattern as opposed to using a resist cover. Thus the number of fabrication processes and the fabrication costs are decreased and the increase in defect rates due to contamination is prevented, resulting in maximized reliability.

摘要： Disclosed herein is a piezoelectric actuator. According to the present invention, the manufacturing cost of the piezoelectric actuator can be reduced by simplifying the patterns of electrodes constituting the piezoelectric actuator, the piezoelectric actuator itself or an electronic product employing the piezoelectric actuator can be made smaller by using only planar simple translational movement of the piezoelectric actuator, and the piezoelectric actuator capable of independently performing linear translational movement in two directions on the plane can be provided.

摘要： A method for controlling a call reception operation in a wide area radio pager, which is capable of providing a continued stable radio call service to the radio pager without generating errors in receiving radio call signals even when the user of the radio pager is positioned in a boundary area between adjacent areas during his area movement. Radio call signals, which are transmitted from a base station, are carried with identification data containing information associated with an area reported to the communication company end as a destination area to which the user of the associated wide area radio pager is to move. Based on such area movement ID data, the radio pager recognizes the destination area to which the user of the radio pager is to move. When an area movement of the radio pager occurs, the receiving channel of the radio pager is changed using only the channel associated with the area represented by area movement ID data received at the radio pager, without using channels associated with all available areas one by one in a predetermined order. Therefore, there is no channel reception nor area recognition error in boundary areas.
