Patent EP-0539963-A2 (EP)
Inventor: KADOMURA SHINGO
IPC: H01L29/778
Filed: 1992-10-28
Abstract: A method of dry etching a GaAs/AlGaAs stacked system with high selectivity without employing a chlorofluorocarbon (CFC) gas. When selectively etching an n⁺-GaAs layer stacked on an n⁺-AlGaAs layer for forming e.g. a gate recess of a high electron mobility transistor (HEMT), a gas having a composition capable of yielding free sulfur (S) and fluorine radicals (F*) in a plasma under conditions of discharge dissociation is used as an etching gas. S is deposited on a pattern sidewall to form a sidewall protection film to contribute to anisotropic etching. On the other hand, F* plays the role of formation of AlF X  with low vapor pressure on an exposed surface of the underlayer of n⁺-AlGaAs to stop etching, to say nothing of a role of an etchant. Although a gas system which is by far the simplest is a mixed system of S₂F₂/Xe, a gas system may be employed which is capable of generating Cl* or Br* for producing a reaction product having a high vapor pressure or augmenting S deposition. More concretely, mixed systems of S₂F₂/Cl₂, S₂F₂/S₂Cl₂ or S₂Cl₂/ClF₃ may be employed.

Abstract: An arrangement is presented for an actuation system of a passenger protective device for a motor vehicle. The system is equipped with a storage device to successively input a newer acceleration signal from an acceleration sensor at every division period obtained by dividing a measurement period so as to store and update a plurality of the latest acceleration data for the measurement period. The plurality of stored latest acceleration data are summed to obtain an integration value at the measurement period. The system compares this integration value with a predetermined value to detect a collision state of the motor vehicle. When detecting the collision state of the motor vehicle, the system actuates the passenger protective device. This system arrangement can improve the vehicle collision decision accuracy.

Abstract: Method and means are described which provide a way for an application program to be generated to include dependency control blocks which indicate which support programs must be initialized in the run-time support environment prior to the application program's initialization and which must be terminated after its termination. Since support programs may be dependent on each other, a topological sort is performed to determine an order in which the support programs can be initialized so that no routine is initialized before all of its prerequisites are initialized. The initialization order is saved, so that following the execution of the program, termination can be performed in the reverse order.

Abstract: In a method and apparatus for detecting ply defects in a pneumatic tire, measurements on the tire are obtained at two levels of tire inflation, and the data obtained in the two measurements are compared. Broken reinforcement cords in the tire cause changes in the peaks of the data obtained at the two inflations that is out of proportion when compared to data changes observed in non-damaged tires. The apparatus of the invention provides means for inflating tires to predetermined pressures and has displacement sensors for measuring peaks and valleys in the sidewall of a tire. The apparatus may also include a computer for collecting data, analyzing data, and providing a signal when a defective tire is recognized.

Abstract: An unknown handwritten symbol written on a digitizing tablet is compared with symbols in a predefined `alphabet' or library of model symbols and the closest match chosen. Recognition is independent of the size, position or orientation of the symbols. The alphabet can be any collection of symbols, such as alphanumeric characters, ideograms or words in cursive script and is created by writing at least one example of each symbol on the tablet. A sequence of samples of the pen position is recorded while a symbol is being written. The samples form a vector, which is then translated (45) so that the centroid of the symbol lies at an origin. The comparison, which can easily be done in real time, involves calculating (46) a correlation factor from scalar products of the vector (v α ) for the unknown symbol and two versions (v k  and u k ) of the vector for each model symbol and choosing (49) the model symbol having the highest correlation factor. If needed to distinguish between model symbols with similar correlation factors, the comparison can also include calculating a rotation factor from such vectors for use in making such choice. Embodiments of the invention can be configured that are user-independent, user-dependent or that evolve from one to the other.
