Abstract: PURPOSE: An apparatus for supplying a call waiting service of a telephone is provided to display a telephone number of an optional subscriber on a liquid crystal display(LCD) of a registered call waiting service subscriber's telephone, when a call is made from the optional subscriber while the registered call waiting service subscriber talks over the phone with a specific subscriber. Therefore, the registered call waiting service subscriber can maintain a present call with the specific subscriber or convert the present call into a call with the optional subscriber by recognizing the displayed telephone number. CONSTITUTION: A ring signal detector(4) detects a ring signal supplied from a telephone office through a transceive block(2), and supplies the ring signal to a micro computer(6). The microcomputer(6) drives a telephone output block(8) to make the telephone output block(8) ring a telephone bell. When a call is made from an optional subscriber while a user talks over the phone with a specific subscriber through the transceive block(2), the microcomputer(6) receives a character signal of the optional subscriber to decode the character signal, and supplies the decoded character signal to a character signal generator(14). The user talks over the phone with other party through a handset block(10). A key input block(12) supplies a specific key signal to the telephone office through the microcomputer(6) and the transceive block(2) by key operations of the user, and selects whether a call is converted into the call of the optional subscriber. The character signal generator(14) generates a character signal for displaying substantial characters on the basis of the decoded character signal, and supplies the generated character signal to a liquid crystal display(LCD) block(16), so that the user may see a telephone number of the optional subscriber through the LCD block(16).

In adding a force in an opposite direction, the end of the second rotary member(254) is hung in the saw-tooth(242). In continuously adding the force, a saw-tooth wheel(240) is rotated anticlockwise. A bolt(260) is rotated anticlockwise and a supporting bar is lowered. The handle(252) is rotated clockwise after sufficiently rotating anticlockwise. The second rotary member(254) is crossed over the saw-tooth(242). The supporting bar is lowered again by rotating the saw-tooth wheel(240) anticlockwise after sufficiently rotating the saw-tooth wheel(240) clockwise. In repeating these steps, the supporting bar(240) is lowered to a lower position than a wheel. The supporting bar supports a load of the bogie and the wheel is hung in the air.

Abstract: PURPOSE: A control method of a convection fan for a microwave oven is provided to control the flow of the air circulating into a cavity. CONSTITUTION: A user selects a cooking mode, and a control unit decides if the selected cooking mode requires strong heating power like baked fish. The control unit controls the rotational direction of a motor. To rotate the motor clockwise or counterclockwise, the control unit turns on switches(S1,S2) or another switches(S3,S4) selectively. If the user selects baked fish, the control unit decides the need of clockwise rotation and turns on the switches(S1,S2). A fan is rotated clockwise, and plural heaters are turned on. When setting a cooking time of 3min, the fan is rotated clockwise. The cold air in the cavity flows into a heater chamber and exchanges heat from the heaters. The heat-exchanged air is supplied to the cavity to be directly injected to a load at the center of the cavity. Therefore, the load receives the heat from the heaters to be heated by very strong heating power.
