  • Patent number: 5723899
    Abstract: A lead frame for semiconductor packages is disclosed. In the lead frame, some of the inner leads in the four sides are extended and provided with connection bars on their inside ends. Alternatively, diagonally arranged tie bars of the lead frame are extended and provided with a rectangular guide ring on their inside ends. The connection bar or guide ring functions as a dam for restricting possible overflow of adhesive, which adhesive is applied on the heat sink for bonding a semiconductor chip to the heat sink. The lead frame of the invention also prevents waste of expensive tape by letting the adhesive tape adhere only to the connection bars or to a given portion of the guide ring when mounting the lead frame to the heat sink and makes it possible higher integration of semiconductor chip by making connection bar and guide ring from the lead or the tie bar.

  • Patent number: 5724410
    Abstract: A two-way voice messaging terminal for communicating with a receiving terminal which may or may not be capable of reproducing a voice message transmitted from the voice messaging terminal. A voice message is digitally encoded and stored in a memory. A receiving terminal selection unit connected to the first memory preferably allows for the selection of the receiving terminal(s) to which the voice message is to be transmitted. The receiving terminal selection unit then receives the stored, digitally encoded voice message and determines whether the selected receiving terminal(s) is(are) capable of reproducing the voice message. If the receiving terminal(s) can reproduce the voice message, the voice message is transmitted to the selected receiving terminal(s). If the terminal(s) is(are) not capable of reproducing the voice message, the voice message is converted into a text message in a speech-to-text converter in the voice messaging terminal and then transmitted to the selected receiving terminal(s).

  • Patent number: 5724298
    Abstract: A data storage device requires a nominal input supply voltage, within a range having upper and lower tolerance limits in which stored data is retained. A capacitor is coupled to the data storage device. A supply voltage has a voltage greater than at least the upper tolerance limit. A regulator energized by the power supply provides a regulated voltage to the data storage device and the capacitor, the regulator presenting a low leakage discharge path for the capacitor. A feedback circuit is coupled to the regulated voltage and the regulator, the regulated voltage being held, preferably precisely held, at a voltage level between the nominal input supply voltage and the upper tolerance limit. The capacitor energizes the data storage device following an interruption of power from the power supply, discharging very slowly through the low leakage discharge path. The stored data is retained for an extended period of time.

  • Patent number: 5721489
    Abstract: A metal detector utilizes digital signal processing and a microprocessor to process buffers of information which is received at a periodic ram. Both high and low gain phase quadrature and in-phase signals are provided via a multiplexer to an analog-to-digital converter from a first receive antenna. A second receive antenna provides phase quadrature and in-phase signals also through the multiplexer to the analog-to-digital converter. The received signals are averaged, decimated and low pass filtered to eliminate noise and reduce the quantity of data which must be processed. A threshold (triggering) processing operation is performed to determine whether a valid target signal is present in the dam. If not, no further processing is performed. The in-phase and quadrature components are processed using Fourier transforms to select a frequency band which includes the energy for the target signal. The energy in this frequency band is utilized to determine the identification of the target.

  • Patent number: 5721594
    Abstract: A differential transconductance amplifier having a fixed value of differential transconductance provides a video output signal current directly proportional to the transconductance of the amplifier and to a difference between first and second differential video input signals supplies thereto. A pair of buffer amplifiers couples the video input signals to respective inputs of the differential transconductance amplifier via respective diode switches which provides Vber protection for the buffer transistors and provides bus isolation under power down conditions. An output circuit regulates the output voltage of the differential transconductance amplifier at a substantially fixed voltage and converts the output signal current to an output signal voltage. Advantageously, the receiver provides very accurate signal gain control unconditional stability, a wide common mode input voltage range, avoids the need for stand-by power and will not load the input bus under power-down conditions.
