Abstract: PURPOSE: A clutch pack reduces the thickness of a plate and emits effectively the heat generated on the operation of a clutch. CONSTITUTION: A plate(20) comprises a first plate(22) and a second plate(24). The first plate(22) has many grooves at the one side of a circle type outside lead where many first teeth(21) are formed. The second plate(24) has many second teeth(23), many grooves and a first air-extracting groove(26). Many second teeth(23) are formed at a circle type outside lead for toothed coupling with the first plate(22). Many grooves are formed at an opposite plane combined with a plane where the groove of the first plate(22) is formed. The first air-extracting groove(26) connected with the groove is formed between the first tooth(21) and the second tooth(23) if the second plate(24) is combined with the first plate(22). Therefore, the heat generated at the frictional plane of the plate(20) on clutch operation is stored at the plate(20) and then is discharged through the first air-extracting groove(26). Thus, because the two plates(22,24) have grooves formed thereon for combining with each other are divided and combine two plates to one plate(20). The heat generated at the plate(20) and a clutch pack is prevented by emitting a heat stored at the plate(20).

Abstract: PURPOSE: A call transfer method in an additive system interfaced with an exchanger in No.7 signaling system is provided to reduce a system load by connecting a callee to a client only by using a call input line and cutting off a call input line when a call communication starts, since the call input line itself is in an idle state and can be used in the next service. CONSTITUTION: An exchange transmits an IAM message through the first call input line to an additive system to transfer a call(S11). The additive system transmits an ACM message to the exchanger to establish a call and completes a call connection(S12). The additive system transmits an announcement requesting of a phone number of the callee through the exchanger to a client. When the client depresses a phone number of the callee, a call transfer is requested from the exchanger through a PSTN to the additive system(S13). The additive system transmits the first user to user(USR) message to the exchanger. Upon receipt of the first USR message, the exchanger attempts a call transfer to the call through the new line on the basis of the information contained in the first USR message(S14). The exchanger checks whether the callee answers(S16). If the callee answers, the exchanger informs the additive system that the callee has answered in the second USR message(S15) and applies a release(REL) message requesting restoration of the second input line to the additive system through a pertinent call input line. The REL message includes a command for cutting off the call input line connected between the exchanger and the additive system(S17). Upon receipt of the REL message, the additive system cuts off the call input line connected to the exchanger in response to the REL message(S18) and applies a release complete(RLC) message informing that the second call input line has been completely restored to the exchanger. The call input line is connected, so that a speech path is formed between the caller and the callee and a charging is initiated(S19).

Abstract: PURPOSE: A method for correcting an overlay parameter of a semiconductor device is provided to improve precision of an overlay, by decreasing the possibility that a field composition incapable of being corrected in a stepper is generated when a scanner and the stepper are used as exposure equipment in a photolithography process of a semiconductor process. CONSTITUTION: A layer exposed by a stepper or well-matched with the stepper among layers in progress of a scanner is determined as a reference layer. A pattern of a square type for measuring an overlay is formed on the reference layer. When an exposure process is performed on the reference layer by using a scanner, a wafer parameter is corrected from an overlay value between the layer in progress of the scanner and a lower layer progressed by a previous scanner. A field composition of the overlay value is an average value of the field compositions. One of the field compositions is obtained from the overlay value between the layer in progress of the scanner and the lower layer progressed by the previous scanner. And, the other of the field compositions is obtained from an overlayer value between the layer progressing to the scanner and the reference layer. An error of the field composition occurring when a process by the stepper is performed after an exposure process is carried out by using the scanner, is reduced.
