Title: Method and device of silicon fusion bonding
Inventor: JU BYONG-KWON
IPC: H01L21/316
Filed: 1991-11-21
Granted: 1994-10-24
Abstract: To increase the bonding strength and to remove the micro-gaps incured at bonding two sillicon wafers, the silicon fusion bonding method and equipment were developed. The equipment is composed of a wet oxidation equipment and a quartz spacer separating two wafers (w1,w2). The wafers are bonded by filling the micro-gaps located at junction interface with the wet oxide through the high temperature thermal annealing, which is followed by the stabilization process absorbing a great deal of oxidant. This method can be applied to growing a silicon on an insulation film and forming the micromachine structure for silicon sensors

Title: Control method of sporadic dehydration for washing machine
Inventor: SON KWON
IPC: D06F33/02
Filed: 1991-11-29
Granted: 1994-05-03
Abstract: A microprocessor (1) determines the corresponding intermittent dehydration frequency and motor (3) on/off time after detecting the laundry quantity. It turns on the motor for a certain time to check the unbalance state. If not unbalance state, it turns off the motor for a certain time and counts the residual pulse numbers to recheck the unbalance state. If the residual pulse numbers are less than the preset one, the intermittent dehydration is performed as much as the maximum number. If the unbalance state happens at any time, the laundry stabilization process proceeds before the next process.

Abstract: PURPOSE: A differential detector for detecting the base band of a pi/4 differential quadrature phase shift keying signal is provided which reduces bit error rate caused by transmission channel characteristic using the characteristic of pi/4 differential quadrature phase shift keying and simplifies a hardware configuration. CONSTITUTION: An absolute phase detector(401) receives sample data items(Wk,Zk) and sets the sample data values to one of four values each symbol can have according to a control signal indicating an odd symbol or even symbol. A differential phase demodulator(307) calculates a sine value and cosine value for differential phase using the data items of the absolute phase detector at the current point of time and the point of time before the current point of time. A data determination unit judges the signs of the data items of the differential phase demodulator to convert the data items into symbol data items(Xk,Yk) corresponding to the signs.
