Abstract: PURPOSE: A method for dehydrating laundries in a drum type washing machine is provided to improve the washing effect by performing the dehydrating process after completely removing foams contained in the laundries. CONSTITUTION: After the washing process is finished, a rotating drum is rotated in the first speed so as to release the tangling of laundries. At this time, a control section determines whether or not foams are contained in laundries by using the variation of the rotational speed of a motor. If the control section determines that foams are contained in the laundries, the form removing process is carried out. If the control section determines that foams are not contained in the laundries, a balancing process is carried out. At this time, an eccentric value of the laundries is measured. If the measured eccentric value exceeds the reference value, the process is repeated. If the measured eccentric value is lower than the reference value, a dehydrating process is intermittently performed by a predetermined time. Then, the main dehydrating process is carried out with maintaining the motor in a second rotational speed.

Abstract: PURPOSE: A method for dry etching for manufacturing a semiconductor device is provided to improve the etching profile by minifying the time loss and the influence of a plasma. CONSTITUTION: A polysilicon gate is patterned on an active area of a substrate(10). A contact window(52) is formed on interlayer insulation film(40) by using a photoresist film(50). Then, an initial atmosphere of a dry etching process is created with a gas mixing ratio corresponding to the main etching ratio when an anisotropic etching process is carried out. The gas mixing ratio is gradually increased as time goes by in such a manner that a gas mixing ratio corresponding to an over-etching process can be achieved when the over-etching process is carried out. The over-etching process is directly carried out without performing a separate stabling step.

Abstract: PURPOSE: The call-cash service method in communication systems is provided to introduce a point saving system for a client's valuable behavior and to make saved points changed into floating money such as mobile communication call charges or prepaid call charges. CONSTITUTION: If a client applies for call-cash service(201), a call-cash system reserves client points by service companies(202) and calculates points by clients(203). The call-cash system analyzes whether the call-cash service subscriber is a PCS subscriber(204). In case that he is a PCS subscriber, the call-cash system transmits client call charge data to his PCS company system(205). The PCS company system reflects the client call charge data to the subscriber's service charge(206). In case that the call-cash service subscriber is not a PCS subscriber, the call-cash system stores the client points in a database(207). If the call-cash service subscriber registers in a PCS, the call-cash system converts the client points into his call charge and transmits the converted charge to the registered PCS company system(208).

Abstract: PURPOSE: A method for processing an outer hand-over of a DECT(Digital Enhanced Cordless Telecommunication) line card in a PBX(Private Branch Exchange) is provided to use the DECT line card comprising one master line card and many slave line cards, so as to simplify a system structure to reduce a cost and to simply install the system. CONSTITUTION: When a user designates the first line card(40-1) as a master, a system reads that the first line card(40-1) is set as the master through a flag or a switch, and performs a HDLC(High-Level Data link Control) protocol by the master line card(40-1). The system designates remaining DECT(Digital Enhanced Cordless Telecommunication) line cards(40-2 - 40-N) as slaves, and perform the HDLC protocol as the slaves. A master BMC(Burst Mode Controller)(41-1) generates a synchronous clock, and applies the synchronous clock to a lower first slave BMC(41-2). The first slave BMC(41-2) applies the synchronous clock from a upper slave BMC to the lower slave BMC. The remaining slave line cards(40-2 - 40-N) receive the synchronous clock outputted from the master line card(40-1), and performs a hand-over between subscribers accommodated in the all line cards(40-1 - 40-N). The master line card(40-1) analyzes all information on a signaling protocol for the hand-over, and synchronizes with the synchronous clock to apply hand-over commands to each slave line card(40-2 - 40-N).

Title: Earphone for portable telephone
Inventor: CHUN JONG HEE
IPC: H04B1/38
Filed: 1999-09-10
Abstract: PURPOSE: An earphone for a portable telephone is provided to eliminate the inconvenience twisted when an earphone is draw out to be used and when an earphone is put in the case after using by separating a cord for connecting an earphone with a jack so as to be concentrated in the earphone. CONSTITUTION: An earphone chamber(2) is formed on the side of the cord entrance which a cord takes in and out when it is drawn out or wound in, thereby a cord remains in putting in a case so long as the earphone is not drawn out. A cord reel(4) winds the cord connected to the earphone or unwinds. When a cord is completely wound on the cord reel(4), an earphone(a) is put in an earphone chamber(2) and the end of a jack(b) is put in a jack receiving place(3), respectively, and the earphone(a) and jack(b) remain in putting in so long as either of them is not drawn out intentionally, thereby they are safely preserved.
