摘要:
A circuit protection device includes a substrate with first and second electrodes connected to the circuit to be protected. The circuit protection device also includes a heater element between the first and second electrodes. A sliding contact is connected by a sensing element to the first electrode, second electrode, and heater element, thereby bridging and providing a conductive path between each. A spring element is held in tension by, and exerts a force parallel to a length of the substrate against, the sliding contact. A flux material is provided around the sensing element. Upon detection of an activation condition, the sensing element releases the sliding contact and the force exerted by the spring element moves the sliding contact to another location on the substrate at which the sliding contact no longer provides a conductive path between the first electrode, second electrode, and heater element. The flux allows the sliding contact to move without dragging the sensing material.

A reflowable thermal fuse includes a conduction element with first and second ends, disposed within a housing. The reflowable thermal fuse also includes an elastic element disposed within the housing and adapted to apply force on the conduction element in an activated state of the reflowable thermal fuse. A restraining element is utilized to secure the elastic element and prevent the elastic element from applying force on the conduction element in an installation state of the reflowable thermal fuse. Application of an activating current through the restraining element causes the restraining element to break and thereby release the elastic element and place the reflowable thermal fuse in the activated state.

Disclosed herein are polypeptides or their derivatives and their application. The polypeptides and their derivatives can treat or prevent cancer. The polypeptides of the invention have significant lethality to the cancer cells when used alone. When its clinical commonly used chemotherapy drugs such as cisplatin in combination, it can significantly increase the sensitivity of chemotherapeutic agents on cancer cells, to enhance its lethality of cancer cells, to reduce the dosage. The peptides can kill a variety of cancer cells, but without apparent toxicity enhancing effect on normal cells. The prepared peptides of the present invention can be chemically synthesized, high-purity, low molecular weight, specificity, non-immunogenic, safe and reliable.

A circuit protection device includes a housing, which includes first and second electrodes. The device includes a conductive slider inside the housing. At a first location within the housing, the slider provides an electrical connection between the first and second electrodes. At a second location within the housing, the slider does not provide the electrical connection. A spring is secured to and stretched between the slider and an inner side of the housing such that the spring is held in tension in an expanded state. The slider is held at the first location by a solder between the slider and the first and second electrodes. After the device is armed, detection of an over-temperature condition causes the solder to begin to melt and the spring to compress and pull the slider to the second location within the housing, thus severing the electrical connection between the first and second electrodes.

The present invention relates to a method for time display on a mobile phone. The method includes the following steps: step 1, in a standby state, set a pseudo power off identifier for the mobile phone; step 2, when the mobile phone identifies that the pseudo power off identifier is active, the mobile phone comes into a pseudo power off state; step 3, the mobile phone continually obtains a new time value through a physical layer clock, and displays the new time value on a LCD; and step 4, the mobile phone quits the pseudo power off state, and restarts. The present invention enables the mobile phone to display time without radio frequency signal by setting a third state, i.e., the pseudo power off state.
摘要:
A thermal fuse includes a first contact surface connected to a top surface of a sensor and a bottom surface connected to a bottom surface of the sensor. The sensor includes a mixture of Sn and Zn. The distance between the top surface and the bottom surface of the sensor is sized to substantially limit Zn depletion in a center region of the sensor when a temperature of the sensor is below a melting temperature of the sensor. The center region of the sensor prevents the first contact surface and the second contact surface from separating when the temperature of the sensor is below the melting temperature, and the first contact surface and the second contact surface are configured to separate when the temperature of the center region of the sensor exceeds the melting temperature of the sensor.

This invention relates to a continuous ultrasonic method and apparatus for breaking the carbon-sulfur (C--S), sulfur-sulfur (S--S), and if desired, carbon-carbon (C--C) bonds in a vulcanized elastomer. It is well known that vulcanized elastomers having a three-dimensional chemical network, cannot flow under the effect of heat and/or pressure. This creates a huge problem in the recycling of used tires and other elastomeric products. Through the application of certain levels of ultrasonic amplitudes in the presence of pressure and optionally heat, the three-dimensional network of vulcanized elastomer can be broken down. As a most desirable consequence, ultrasonically treated cured rubber becomes soft, thereby enabling this material to be reprocessed and shaped in a manner similar to that employed with uncured elastomers.
摘要:
A circuit protection device includes a substrate with first and second electrodes connected to the circuit to be protected. The circuit protection device also includes a heater element. A sensing element facilitates an electrical connection between the first and second electrodes. A flux material is provided around the sensing element. In a preferred embodiment, the flux contains a first component that is a polar material and a second component that is a non-polar material. A spring element exerts a force on the sensing element. The sensing element resists the force applied by the spring element. Upon detection of an activation, or fault, condition, the sensing element loses resilience and no longer resists the force exerted by the spring element, resulting in the spring element severing the electrical connection between the first and second electrodes. The flux allows the spring element to sever the electrical connection without dragging the sensing element.
