摘要:
A portable terminal includes a cover movably coupled to a body, a first solar cell on the body; and a second solar cell on the cover. The first and second solar cells may be oriented in the same or different directions. When oriented in the same direction, both solar cells may receive light when the cover is opened relative to the body. The solar cells output voltages for simultaneously charging a battery when the cover is opened and when voltages from the first and second solar cells exceed a predetermined reference voltage.

Disclosed is a sliding bearing having a sintered layer formed of sintered segments on a sliding side surface of a steel base member, the sintered layer being made of iron group metal powder and solid lubricant and being formed by forcibly compressing the sintered segments, each of which is molded by previously sintering mixtures made of the iron group metal powder and the solid lubricant into a size enough to construct a portion of the whole sintered layer, on the sliding side surface of the steel base member to form the whole sintered layer, and sintering-bonding the sintered segments to each other and also each of the sintered segments to the steel base member.
摘要:
A counter circuit includes a first counter and a second counter. The first counter is configured to count a first counter clock signal which toggles with a first frequency to generate upper (N−M)-bit signals of N-bit counter output signals, in response to a first counting enable signal based on a first comparison signal during a coarse counting interval. N and M are natural numbers, N is greater than M, and M is greater than or equal to 3. The second counter is configured to count a second counter clock signal which toggles with a second frequency which is higher than the first frequency to generate lower M-bit signals of the N-bit counter output signals, in response to a second counting enable signal based on the first comparison signal and a second comparison signal during a fine counting interval which follows the coarse counting interval.
摘要:
A sense amplifier having a negative capacitance circuit receives differential input signals via a pair of data lines, and senses and amplifies a voltage difference between differential output signals corresponding to the differential input signals as loaded by the negative capacitance circuit using a differential-to-single-ended amplifier to generate a corresponding data output signal.

A data transmission circuit includes a data output unit (DOU) connected to a positive data transmission line and a negative data transmission line. The DOU generates a recovered data signal based on data signals communicated via the positive and negative data transmission lines. Data signal driving units are respectively connected at different points along the positive and negative data transmission lines, where each data signal driving unit generates and provides a positive data signal and a negative data signal based on a data input signal and a data transmission distance between the data signal driving unit and the data output unit

A multiple-bonding material applicable to a transportation vehicle is provided. The multiple-bonding material includes a metal plate and a composite. The composite is bonded to one surface of the metal plate, and includes a reinforcement material and a resin composition to bond the reinforcement material to the metal plate, wherein the reinforcement material is formed as a woven or non-woven fabric and disposed on the surface of the metal plate. Accordingly, the multiple-bonding material has improved rigidity and advantage in lighting of the vehicle, and can enhance impact and sound absorption and damping performance.
摘要:
In a method for setting a wake-up alarm of a mobile communication terminal, when a user presses a key of a mobile communication terminal to stop a wake-up alarm, it is determined whether the pressed key is a number key. If so, a snooze time is arithmetically set using a basic time, stored in the terminal, and the value of the number key pressed by the user, such as by addition or multiplication. Therefore, the user may immediately control the snooze time after an alarm. Also, the user may independently set a sound type and/or volume level associated with the wake-up alarm and any subsequent follow-up alarms.
摘要:
A sampling circuit samples an input signal by using at least one switch, at least one capacitor, an amplifier, and a clamp block connected between an output terminal and a negative input terminal of the amplifier. The clamp block prevents a difference between a voltage level of the output terminal of the amplifier and a voltage level of the negative input terminal of the amplifier during sampling from exceeding a maximum voltage difference.
