IPC: H01L21/18
Filed: 1987-06-30
Granted: 1989-11-30
Abstract: The optimization of the initial oxygen concentration of semiconductor in low teperature process is made by using the back side damage wafer for extrinsic gettering effect.  The initial oxygen concentration of the used silicon wafer is 13-14 P.P.M.A. (part per million atom).  As the result, the refresh-time is increased to 25-80msec, and the SER (soft error rate ) is decreased by 30-40%.

Filed: 1989-03-29
Granted: 1992-04-27
Abstract: First, a checking  finds  whether  the  trigger  point  comes within the trigger point range (106), whether the AC power  has  a level over the standard level (107), whether the over-level  lasts longer than the standard duration  (108).  Then  if  the  duration exceeds the standard duration, a buzzer is sounded,  and  a  reset signal is emitted to stop the driving of the fan motor  (109).  If the trigger point departs from the  relevant  range,  and  if  the power level does not exceeds the standard level, the operation  is returned to the duration finding step  (110).  When  the  duration exceeds the standard duration, it is decided that an air filter or a discharge hole is blocked (111). Then the buzzer is sounded, and a reset signal is outputted to stop the driving of the motor.

Abstract: Disclosed is a self diagnostic method for a broadcasting camera which includes a MICOM that a standard signal is embedded, a pulse board that generates all kinds of pulses, an encoder board that all kinds of signals are embedded, a supply voltage board that supplies a necessary supply voltage to each board. The self diagnostic method includes a discriminating step which discriminates whether all the signals are input from the necessary board, calculation step which finds the signal of a board having a difference when comparing with the standard signals and calculates a compensation volume when signals are all input at the signal input step, an input state search step which finds a signal of the board which is not input if there is an input signal at the signal input step, and a display step which displays the results of the compensation volume calculation step and the input state search step. Thus, the abnormality of the camera can be easily checked.

Title: Fan sense
Inventor: KWON TAEK-JUN
IPC: F04D27/00
Filed: 1991-12-14
Granted: 1994-10-14
Abstract: The circuit includes a permanent rubber magnet on a rotor blade, and senses a magnetic force of the magnet by use of a magnetic tape head installed near the rotor blade so that it can prevent the blower from getting heated when it gets malfunctioned. The circuit comprises a signal amplifier (A1) amplifying the signal detected from the magnetic tape head (T/M); a transistor circuit (Q1) , connected to the signal amplifier (A1), operating a switching action; flip flop devices (FF1, FF2) operated based on the output of the transistor circuit (Q1); a diode (D1), connected to the flip flop device (FF1), operating a first alarm action; a relay circuit (R/L), connected to the flip flop (FF2), operating a second action.

Title: Diaper for a single usage
Inventor: SONG JOON-SIL
IPC: A61F13/15
Filed: 1991-12-24
Granted: 1996-06-08
Abstract: The diaper has waved edges on both sides to reduce skin rubbing against the diaper and to improve quality for the safety of skin. The waves at the edges of the diaper have the same or different pitches in a partial or the whole portion of the edge length. The wave pitch is preferred to be a value in the range from 5.0mm to 20.0mm.

Title: Electron gun for c-crt
Inventor: PARK IN-KYU
IPC: H01J29/48
Filed: 1991-12-30
Granted: 1994-10-13
Abstract: The electron gun has a three polar part of a cathode, a control electrode and screen electrode, and a lens field of focus electrode and a final accelerating electrode, in which the focus electrode includes a first electrode receiving a predetermined focus voltage, being placed on the side of cathode, and a second electrode placed on the side of final accelerating electrode, inserted for an insulation with the first electrode, and receiving the focus voltage synchronizing to a deflection signal, taking the focus voltage as a base voltage.
