A CMOS latch-type sense amplifying circuit is disclosed. The circuit comprises a CMOS differential amplifier configured to amplify a voltage signal of an input line pair to generate a first amplified voltage signal pair, and provide the first amplified voltage signal pair to an output line pair, a first pre-charge voltage having a first voltage level being applied to the input line pair. The circuit further comprises a CMOS latch-type sense amplifier configured to amplify a voltage signal of the output line pair to generate a second amplified voltage signal pair, and provide the second amplified voltage signal pair to the output line pair. The circuit additionally comprises a first common node controlled by a first common enable signal and connected to both the CMOS differential amplifier and the CMOS latch-type sense amplifier, such that the first common enable signal controls both the CMOS differential amplifier and the CMOS latch-type sense amplifier.

A temperature detection circuit and method are provided. The temperature detection circuit samples a first delay time for an input signal at a target temperature to be detected, stores a first addresses generated as the sampled result, samples a second delay time for the input address at a present operating temperature, compares a second addresses generated as the sampled result with the first addresses, and generates a detection signal if the target temperature to be detected is the same as the present operating temperature. The temperature detection method is performed by the temperature detection circuit.
摘要:
A washing machine in which the poor heat-resistant laundry is sufficiently wet so that a plurality of water curtain layers are formed at the laundry, thereby preventing the laundry from being stained and damaged when the laundry contacts the steam. According to the present invention, cold water is supplied simultaneously with injection of the steam so that the real temperature of the steam contacting the surfaces of the laundry is lowered, thereby preventing the laundry from being stained and damaged when the laundry contacts the steam.
摘要:
A drum type washing machine in which wash water and laundry contained in a rotating tub are heated by steam supplied into the rotating tub, so as to rapidly increase the temperature of the wash water and laundry, thereby being capable of reducing the total wash time while reducing the amount of wash water to be used, and reducing the consumption of energy caused by heating of the wash water. The washing machine includes a steam generating unit for heating water supplied thereto, thereby generating steam, and a control unit for rotating the rotating tub at a high speed to cause the laundry contained in the rotating tub to be in constant contact with an inner peripheral surface of the rotating tub without falling down, by virtue of a centrifugal force generated during the rotation of the rotating tub, the control unit supplying the steam from the steam generating unit into the rotating tub during the high-speed rotation of the rotating tub, to increase the internal temperature of the rotating tub and the temperature of the laundry.

A seal pattern for a liquid crystal display device includes a substrate having an active area and a non-active area, a main seal pattern having an injection hole arranged in a boundary between the active and non-active areas, and first, second, and third dummy-seal patterns in the non-active area that are arranged along a same direction as a portion of the main seal pattern having the injection hole and spaced apart from each other. The first and second dummy-seal patterns have first and second openings corresponding to opposite ends of the injection hole. The third dummy-seal pattern has third, fourth, and fifth openings arranged alternately in correspondence with the first and second openings.
