摘要:
The invention relates to a reverse rotation preventing structure of a centrifugal compressor. The reverse rotation preventing structure of the centrifugal compressor comprises: a discharge pipeline of the centrifugal compressor; a suction pipeline of the centrifugal compressor; a bypass pipeline for connecting the discharge pipeline and the suction pipeline, wherein a predetermined valve is formed thereon; a control means for controlling an operation of the centrifugal compressor; and a detecting means for generating a predetermined signal to the control means if the operation of the centrifugal compressor is suddenly stopped, thereby opening the bypass pipeline.

Provided is a method for fabricating an organic semiconductor transistor having an organic polymeric gate insulating layer. The method includes forming an organic gate insulating layer on a substrate by a vapor deposition method using organic monomer sources, and causing a polymerization reaction to occur in the organic gate insulating layer to complete an organic polymeric gate insulating layer. Since the vapor deposition method, which is a low-temperature dry-type technique, is employed, the organic polymeric gate insulating layer can be uniformly formed on a large-area substrate by a simplified in-situ process.

摘要:
A washing machine and a method for controlling the same are disclosed. The washing machine detects a back electromotive force of a washing motor, and controls output of an alarm sound by analyzing periodicity of a waveform period of the back electromotive force. The washing machine determines whether a child or pet is in a drum washing machine on the basis of the back electromotive force generated from the washing motor, and informs a user or guardian of the determined result.
