Publication number: 20160285460Abstract: An oven controlled crystal oscillator using an embedded heating device package is disclosed. The oven controlled crystal oscillator, which is different from the conventional technology using a heating source independent from a quartz crystal package, integrates a heating resistor in a ceramic package structure of the quartz crystal and cooperates with a temperature-controlled circuit to heat a quartz blank in the quartz crystal package, thereby shortening thermal conduction paths, increasing thermal conduction efficiency and greatly reducing thermal dissipation. The present invention further uses an exterior and independent heating resistor, combining with the heating resistor in the quartz crystal package and controlled by the temperature-controlled circuit to form a sandwich structure so that heat is more concentrated to use, thereby stabilizing the interior temperature of a constant temperature oven and the output frequency of an oscillator.Type: ApplicationFiled: March 10, 2016Publication date: September 29, 2016Inventors: CHIEN-WEI CHIANG, CHE-LUNG HSU, CHEN-YA WENG, CHIA-WEI CHEN

Patent number: 9358239Abstract: The accumulation of abnormal proteins in neurodegenerative disorders is considered to induce oxidative stress and lead to cell death. Thus suppression of abnormal protein aggregation and reducing oxidative stress or reactive oxygen species (ROS) are expected to inhibit a wide range of harmful downstream events, providing an observation for identifying the potential prevention and treatment of neurodegenerative disorders comprising spinocerebellar ataxia (SCA), Alzheimer's disease (AD) or Parkinson's disease (PD). In the present invention, there are several cell and animal experiment models for SCA, AD and PD established, and NiSOD-like compounds were applied to these experiment models. The results have demonstrated how NiSOD-like compounds are likely to work in suppressing abnormal protein aggregation, recovering cell viability, increasing mature neuron number and neurite outgrowth length and protecting dopaminergic cells by reducing oxidative stress or reactive oxygen species in brain tissues.Type: GrantFiled: January 26, 2015Date of Patent: June 7, 2016Assignee: National Taiwan Normal UniversityInventors: Way-Zen Lee, Guey-Jen Lee, Hsiu-Mei Hsieh, Chien-Wei Chiang, Bin Huang, Yaw-Syan Fu, Yun-Ming Wang

Publication number: 20150077190Abstract: A package structure of crystal oscillator with embedded thermistor is disclosed. The package structure comprises a ceramic substrate. A crystal oscillation device is mounted in the accommodation space of the ceramic substrate. A cover is used to seal the accommodation space. At least one thermistor is embedded in the ceramic substrate. A patterned metal interconnection in the ceramic substrate is electrically connected with the crystal oscillation device and the thermistor, respectively. The present invention describes as follows: the thermistor is directly embedded in the ceramic substrate to avoid the short-circuit problem caused by electroplating a thermistor exposed and shorten a distance between the thermistor and the crystal oscillation device. Thus, the thermistor can more precisely sense the operating temperature of the crystal oscillation device to timely compensate frequency drift caused by changing the temperature of the crystal oscillation device.Type: ApplicationFiled: December 12, 2013Publication date: March 19, 2015Applicant: TXC CORPORATIONInventors: CHIEN-WEI CHIANG, TING YEH
