Title: Radio frequency identification transponder and method of clamping the transponder supply voltage
Inventor: DAWES ALAN M
IPC: H02H9/04
Filed: 1998-09-15
Granted: 2000-09-11
Abstract: A radio frequency identification (RFID) tag includes a tank circuit for receiving a power signal transmitted on a radio frequency (RF) carrier by a remote interrogator unit. Information is conveyed from the tag to the interrogator by varying a resistive load placed across the tank circuit as a function of data read from memory. Corresponding variations in the reflected signals are then detected by the interrogator. An overvoltage circuit cooperates with a modulation circuit for providing transmission of data even during an overvoltage condition, thus avoiding masking of the signal under such conditions.

Title: Broadcast paging reception method with data selection and time setting functions
Inventor: MA HUEI-CHIUN
IPC: H04Q1/30
Filed: 1998-12-02
Granted: 2001-12-01
Abstract: A data selection method in data broadcast paging reception system can enable the user of a paging device to select the intended data to be received in data broadcasting and the receiving time frame, thereby allowing paging device to follow the selected channel and time frame in receiving data. The method is as follows. The user of paging system sets up the broadcasting data channel and time frame to be received in the paging system according to the channel directory table. When the paging device is receiving the data broadcasting signal, it is determined the forwarding address code and time of the broadcasting data. If these match the preset receiving channel address code and time, paging device starts receiving the broadcasting data in channel and display it. If the forwarding address does not match the preset receiving channel address code or the forwarding time of signal does not match the preset receiving time, paging device will shut down the channel.

Title: Method for forming solder bumps on flip chips and devices formed
Inventor: KUNG LING-CHEN
IPC: H01L21/60
Filed: 1999-03-30
Granted: 2001-01-11
Abstract: A method for forming solder bumps on flip chips and a structure thereof is disclosed. According to the bonding technology of flip chips, the present invention provides a method for forming solder bumps on flip chips with minute clearance, and discloses a method of forming solder bumps with minute clearance by using a double photolithography technique together with a double photoresist layer; in which the first photolithography technique uses a thin photoresist to define a BLM layer to a required location, and the second photolithography technique uses a thick photoresist to open an aperture desired to grow a solder bump and define the height of the solder bump grown; in which the thickness of the thin photoresist used in the first photolithography technique is very thin, the alignment there has a high precision. Therefore, a minute location of the solder bump to be grown can be accurately defined. Furthermore, even though the thickness of the photoresist used in the second photolithography is thicker and its alignment accuracy is poorer, the self-alignment process of the solder bump per se can fully follow the location of the solder bump defined in the first photolithography technique to grow into a solder bump with a minute clearance.

Title: Method and device capable of implementing a write operation to a none-volatile memory unit by controlling the pull-down rate of source current
Inventor: LIN JIN-SHI
IPC: G11C16/00
Filed: 1999-05-18
Granted: 2000-08-01
Abstract: The method and device can implement a write operation to a none-volatile memory unit by controlling the pull-down rate of source current. The current rate passing through the unit is controlled by a current limiter, which is connected to the source node of the memory unit. The current rate passing through the current limiter is used to control the current needed to pass through the memory unit when the unit is in write operation. The current limiter is controlled by an input port, which is determined according to a setting in co-operation with the current of the current mirror device. The current of the current mirror is controlled by a preset input port condition at the current source. A bias circuit generates a proportional input to the current limiter by utilizing the current mirror. The current source controls the current limit rate. The current source and the memory unit are formed in the same process. The output port varies corresponding to the conductivity of the formed device. Hence, the variation in the current source output port and the current of the current limiter can be used to compensate for the conductive variation in the memory unit. The current rate of write operation is therefore controlled. Furthermore, it also can be controlled according to the process variation in the memory unit device.

Title: Shadow mask positioning structure of color cathode ray and method of the same
Inventor: TUNG HUA-SU
IPC: H01J29/07
Filed: 1999-10-12
Granted: 2001-05-28
Abstract: The present invention is a shadow mask positioning structure of color cathode ray and method of the same. There is disposed securely at least a shadow mask positioning device at the corresponding position of any side of the glass envelope of the cathode ray tube and the peripheral frame of a shadow mask, and the material of the positioning device is the same with the shadow mask. One end of the device is fixed directly on the frame of the shadow mask along the vertical direction, and the other end thereof is fixed inside the glass envelope along the vertical direction by the convex cylinder. The section between two fixed ends is bent into two reversely symmetric first middle part and second middle part, so that the positioning device can compensate the heat expansion generated by itself when the RGB electron beam of the color cathode ray tube performs the image developing scan and thereby heats the shadow mask. The shadow mask can therefore keep an expectable position and direction to avoid the occurrence of rotational shift of the shadow mask centered at the center position of the cathode ray tube effectively, which ensures that the aperture of the shadow mask can make the RGB electron beam be projected accurately onto the phosphor deposit at the corresponding position inside the display screen and enhances the color purity of the video image effectively.
