    摘要： A method of forming a piezoelectric resonant device having a piezoelectric resonator is provided. The method offers a plan for increasing the electrical characteristics of the piezoelectric resonator by ensuring a green substrate having a desired thickness from a green body. According to the method, two green bodies are prepared. Green substrates are formed by sequentially performing sintering and grinding processes on the green bodies. Internal and external substrate electrode patterns are formed on facing surfaces between the green substrates and opposite surfaces to the facing surfaces. An adhesive agent is formed on the facing surfaces between the green substrates. A piezoelectric resonant pattern is formed by cutting the green substrates. A piezoelectric resonator is formed by disposing respective connection electrodes on both sides of the piezoelectric resonant pattern.

    摘要： A bi-directional detector which enables a host and a client in a collection terminal is disclosed. The bi-directional detector includes a client detection unit in the host part, for detecting the clients connected to the host part; a client identification unit for identifying types of the clients detected by the client detection unit; a host detection unit in each of the clients for detecting the host part; and a switch unit in each of the clients for determining whether to apply comparison power to the client detection unit and the host detection unit according to whether power is applied to the client. In the bi-directional detector, the client directly detects the host part and manages the connection, thereby reducing the load on the host part, without performing a step by which a host part responds to a connection request of a client.
