Patent EP-0678905-A2 (EP)
Inventor: HAYS KENNETH M
IPC: G01L9/00
Filed: 1995-02-20
Abstract: A dissolved wafer micromachining process is modified by providing an etch control seal around the perimeter of a heavily doped micromechanical structure formed on a substrate. The micromechanical structure is fabricated on a wafer using conventional methods including the formation of a trench that surrounds and defines the shape of the micromechanical structure in the substrate. The etch control seal comprises a portion of the substrate in the form of a raised ring extending around the perimeter of the micromechanical structure and its defining trench. Selected raised areas of the heavily doped micromechanical structure and the top of the raised etch control seal are bonded to a second substrate. A selective etch is then used to dissolve the first substrate so that the heavily doped micromechanical structure remains attached to the second substrate only at the bonded areas. The etch control seal reduces exposure of the micromechanical structure and bonded areas to the etch by preventing the etch from contacting the heavily doped structure until the etch leaks through the dissolving floor of the trench. This occurs only during the final stages of the substrate dissolution step, thus minimizing exposure of the micromechanical structure and bonded areas to the damaging effects of the etch. Use of an etch control seal increases design flexibility and improves micromechanical device yield and quality in a dissolved wafer fabrication process.

Abstract: The measuring system allows the electrical parameters of the asynchronous motor to be determined when the motor is at a standstill, by determining the resistance of the motor and the current regulator supplying it when a given reference voltage is applied to the latter. The actual voltage of each motor strand and the stator resistance is determined via a linear regression method using the measured strand current and the given reference voltage, with the current/voltage characteristic used for determining the stray inductance and the rotor resistance in the linear upper range. The main inductance is determined from the current characteristic for a given voltage value and the corresponding stator flux characteristic, with repetition for different voltage values.

Inventor: KIM BYEONG-JUN
IPC: H05B6/76
Filed: 1995-12-12
Abstract: A choke structure of microwave oven door which can effectively protect a human body by shielding the microwave leakage to outside is disclosed. The choke structure comprises a drawn side wall provided by bending from the sealing surface opposite to the front panel, a lower choke wall bent by extending outwards from an end of the drawn side wall, an outer choke wall bending by extending from an end of the lower choke wall toward the sealing surface, and an upper choke wall bent by extending from an end of the outer choke wall toward the drawn side wall. The length of the microwave transmission path is 1/4.λ 0  wherein, λ 0  is the free space wavelength of microwave. The choke structure has a plurality of slits for dividing the choke structure into a plurality of chokes to form plural open longitudinal paths. The holes for reinforcing impedance are formed at portions of the lower choke wall opposite to the slits formed at the choke structure. A large impedance is formed in view of circuitry between the front panel of a cooking chamber and a sealing surface of a door frame contacted thereto. Thus, almost the leaked microwave disappears by short-circuiting at the inner surface of the final short longitudinal surface from the opening of the choke structure as a starting point.

Abstract: An intelligent terminal (which can be a telephone (101-2, 101-3), a facsimile machine (101-4), or similar device (101-1)) is arranged so that (a) it can store information indicating when (e.g., date and time) a particular subscriber last was present at the terminal, and (b) the stored information can be retrieved from the terminal remotely, preferably without completing a conventional call to the terminal. A central processor (114) contains, for each subscriber, a list of the intelligent terminals that have been pre-designated for use by that subscriber, and has the ability to query terminals on the list. In response to a call placed to the subscriber by dialing the subscriber's unique personal number, specific intelligent terminals on that subscriber's list are queried by the central processor to determine when the subscriber was last present at each terminal. The central processor then generates a control signal such that the call is then completed to the particular terminal that was most recently visited by the subscriber.

Abstract: A bandgap reference generator providing a reference voltage V R  from a power supply voltage V DD . The bandgap reference generator includes a bandgap reference circuit and a voltage regulation circuit coupled thereto. The voltage regulation circuit operates to supply power to the bandgap reference circuit such that the voltages at a first internal control node and a second internal control node are equal, wherein the first internal control node and the second internal control node are disposed on different current paths within the bandgap reference circuit. By equalizing voltages at these internal control nodes, device stress within the bandgap reference circuit is reduced. Kick-start circuits for the voltage regulation circuit and the bandgap reference circuit are also included within the bandgap reference generator. In addition, output stage processing can be incorporated to transform an outputted reference voltage V R  from a low stress operating point to a desired reference voltage V REF .
