20140103993 | CHIP DYNAMIC VOLTAGE REGULATOR CIRCUIT AND TERMINAL DEVICE - The present invention provides a chip dynamic voltage regulator circuit and a terminal device. The voltage regulator circuit includes: a parameter detecting module, configured to detect an attribute parameter of a chip; a Pulse Width Modulation (PWM) signal generating module, configured to generate a corresponding PWM digital signal according to the detected attribute parameter, and convert the PWM digital signal into an analog signal having a direct-current voltage; and a power supply module, including a DC-DC converter or a low-dropout regulator, which is configured to regulate an output voltage according to the analog signal that is fed back and a feedback signal of the voltage output end of the voltage regulator circuit. The present invention is capable of accurately regulating an output voltage according to an analog signal converted from a PWM digital signal, thereby implementing dynamic voltage regulation for a chip at a low cost and avoiding power waste. | 04-17-2014 |
20150276819 | Method and Apparatus for Determining Resistance Values of Dynamic Voltage-Adjusting Circuit - A method and an apparatus for determining resistance values of a dynamic voltage-adjusting circuit are provided. The method includes determining a reference voltage, a maximum output voltage value, and a minimum output voltage value of the dynamic voltage-adjusting circuit; determining, according to the reference voltage, the maximum output voltage value and the minimum output voltage value, a first relational expression between the reference voltage, the maximum output voltage value, and multiple resistors of the dynamic voltage-adjusting circuit, and a second relational expression between the reference voltage, the minimum output voltage value, and the multiple resistors; and determining a group of resistance values of the multiple resistors according to the two relational expressions. It is ensured that voltage values output by the dynamic voltage-adjusting circuit can fall within a same range when the reference voltage takes different values. | 10-01-2015 |

20140134037 | MOLYBDENUM-NIOBIUM ALLOY PLATE TARGET MATERIAL PROCESSING TECHNIQUE - The processing technology of a molybdenum-niobium alloy plate target shall be implemented as follows: (1) mix: divide a certain amount of molybdenum powder and niobium powder into, at least, three small portions, and mix each portion of them into a mixed powder. After several rounds of mixing and sieving, a mixed alloy powder will be achieved from a plurality of mixed powders; divide the mixed alloy powder into three portions and mix each portion with other materials, a uniform alloy powder will be obtained by mixing the three portions together; (2) shaping: the alloy compact, which is formed after isostatic pressing, shall be sintered in a high-temperature intermediate frequency furnace for at least 3 hours under protection of hydrogen. The sintering temperature includes three zones, i.e. 0° C.˜800° C., 800° C.˜1600° C. and 1600° C.˜2000° C., and the alloy compact shall be sintered in each of the three temperature zones. An alloy compact shape will be formed in the end; (3) forging and rolling: after the forging and densification under a temperature of 1200° C.˜100° C., the alloy compact is rolled into the plate for material preparation under a heating temperature of 1500° C.˜1600° C.; (4) finish machining: the final molybdenum-niobium alloy plate target is achieved by cutting, accurate grinding and machining. The blank of the invention is the refined grain with a relatively uniform size. | 05-15-2014 |

20100012003 | Safes without weak parts - The security class or burglary resistant capability of a safe is determined by the safe's weakest parts: combinations lock, key lock, keyboard, LCD screen, card reader, fingerprint scanner, etc (referred as weak parts below). The results of an attack to the safe include opening safe door, digging holes on safe door or body, or dysfunction of the above weak parts. The corresponding consequences are: Objects deposited inside the safe are stolen or destroyed. Even if those objects stay intact, the safe owner is no longer able to operate the safe. A new design method about safe is disclosed in this invention. The new safe has no weak parts on its surface. It's obvious that weak parts are easier to destroy than safe door and body, which is why they are called weak parts. For safes without weak parts on their surface, these weak parts (in user's hand or inside safe) are not so easy to be attacked on. The GSA class or UL Certification is improved for the new safe. Users will find the new safe is more secure and convenient to use. The design method applies to other security containers and doors. | 01-21-2010 |
