Title: Twin-notch loaded type microstrip antenna
Inventor: DENG SHENG-MING
IPC: H01Q5/364
Filed: 1999-09-03
Granted: 2001-04-21
Abstract: This invention is about a kind of twin-notch loaded type microstrip antenna and is composed of single medium layer, metal layer and microstrip antenna. Metal layer is located under the single medium layer and is grounded. Microstrip antenna is located above the single medium layer and has the structure with a pair of twin-notch or single twin-notch shape. In this invention, single-layered substrate is used to obtain dual-band or multi-band function. Because signal is directly fed to microstrip through a small opened hole on the grounded surface of single medium layer, it is not necessary to perform further treatment onto single-layered substrate so as to obtain simplified fabrication and avoid the problems such as alignment, precision of cutting substrate, gap insertion and so on. In addition, because single-layered structure is used in this invention, the problems of alignment, poor connection can be avoided so as to achieve the purpose of saving production cost at the same time.

IPC: H04L49/901
Filed: 2000-01-05
Granted: 2001-09-01
Abstract: A packet accessing method with parallel multiplexing feature uses a descriptor corresponding to a data buffer to receive network packets. The size of data buffer is fixed as the maximum of network packet. Following the software protocol, data buffer is divided as several parts in terms of a critical value and each division point corresponds to a early receiving interrupt signal, indicating that the controller of data link layer has moved partial network packet data defined by critical value to the data buffer specified by descriptor. After the controller of data link layer receives entire network packets and transmits to the specified data buffer, the controller of data link layer will proceed a write-back operation to descriptor concerning the status of receiving network packet and then issue a complete interrupt signal to let network software driver finish the movement of remaining packet data.

Inventor: LI TINGKAI
IPC: H01L29/788
Filed: 2000-04-28
Granted: 2003-07-01
Abstract: A ferroelectric Pb5Ge3O11 (PGO) thin film is provided with a metal organic vapor deposition (MOCVD) process and RTP (rapid thermal process) annealing techniques. The PGO film is substantially crystallization with c-axis orientation at temperature between 450 and 650 DEG C. The PGO film has an average grain size of about 0.5 microns, with a deviation in grain size uniformity of less than 10%. Good ferroelectric properties are obtained for a 150 nm thick film with Ir electrodes. The films also show fatigue-free characteristics: no fatigue was observed up to 1x10<9> switching cycles. The leakage currents increase with increasing applied voltage, and are about 3.6x10<-7> A/cm<2> at 100 kV/cm. The dielectric constant shows a behavior similar to most ferroelectric materials, with a maximum dielectric constant of about 45. These high quality MOCVD Pb5Ge3O11 films can be used for high density single transistor ferroelectric memory applications because of the homogeneity of the PGO film grain size.

Title: Switching power supply apparatus with active clamp circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M3/338
Filed: 2001-05-01
Granted: 2003-02-21
Abstract: An active clamp circuit is provided on the primary side of a complex resonance type switching converter having a voltage resonance type converter on the primary side and a parallel resonant circuit on the secondary side. The active clamp circuit clamps a parallel resonance voltage pulse generated across a primary-side parallel resonant capacitor to thereby suppress the level of the parallel resonance voltage pulse. Thus, products having low withstand voltage may be selected for components such as switching devices and the primary-side parallel resonant capacitor provided in the power supply circuit. An auxiliary switching device Q2 of the active clamp circuit is driven by a self-oscillation circuit formed by winding a wire of the primary winding of an insulating converter transformer by 1T. Thus, the circuit system for driving the active clamp circuit is simplified, thereby improving power conversion efficiency and miniaturizing the power supply circuit.
