Abstract: The alarm sound controlling circuit for sensing abnormal state of a terminal in a remotely-controlling service system using MDF includes a CPU, a watchdog circuit, a multivibrator and a logic circuit, and an alarm sound generating circuit is operated by supplying a live signal and an alarm sound control signal during a normal operation of the terminal to generate the alarm sound, sensing the abnormal state when stopping the live signal for a predetermined time to supply an alarm sound control-off signal, and receiving the alarm sound control-off signal to stop the alarm sound, thereby preventing the half of service due to malfunction and accurately sensing abnormal state of the terminal.

Title: Manufacturing method of silicon thin film
Inventor: CHOE JONG-MUN
IPC: H01L21/20
Filed: 1991-12-23
Granted: 1995-07-28
Abstract: The manufacturing method of single crystal silicon film comprises a process for depositing a silicon thin film at the of above 590≰C by air, a process for injecting silicon ions to the silicon thin film at the angle of 46 degree, and a process for heating a silicon thin film at below 520≰C to form a silicon thin film of big crystalline grains. The manufacturing method of polycrystal silicon comprises a process for depositing a silicon thin film at below 570≰C by air to form a silicon thin film of big crystalline grains, a process for injecting silicon ions to the silicon thin film at the angle of 30-60 degree to break crystalline grain groups, and a process for heating the ion-injected silicon thin film at 450-550≰C.

Title: Pre-heating fuel injector
Inventor: CHOE MYONG-SHIK
IPC: F02M51/06
Filed: 1991-12-27
Granted: 1995-10-07
Abstract: The preheating type fuel injector, for injecting the fuel in a liquid state with high temperature and high pressure, is characterized in that an insulation material(32) is interposed between the upper and lower portions of a valve body, a heater is embedded in the lower body, and a jacket connected to cooling water of an engine is formed at the upper portion of the lower body.
