Patent EP-0248677-A2 (EP)
Inventor: HAMANO SUENOBU C O CHUO KENKYU
IPC: H01H33/18
Filed: 1987-06-05
Abstract: A switchgear comprises, in a housing containing an arc extinguishing gas, a pair of separable contacts 2, 3 defining therebetween an arcing region in which an electric arc is generated when the contacts are separated. A cylindrical wall 6 and an insulating nozzle 22 are provided for defining a gas storage chamber 9 around the stationary contact, communicating with the arcing region, for storing the arc extinguishing gas to be increased in pressure by heat from the arc. The insulating nozzle defines an opening through which the movable contact 3 movably extends and through which the pressurized arc extinguishing gas flows. Around the arcing region a magnet 21 is disposed for generating a magnetic field in the opening of the gas storage chamber for rotating and elongating the electric arc generated in the arcing region upon current interruption. The specification describes novel arrangements of the magnet and a novel design of the nozzle, for enhancing the arc-extinguishing capability.

Title: Apparatus for producing a hollow plastic body with an open and a closed end
Inventor: LINSZ GERHARD
IPC: B29C49/02
Filed: 1988-02-04
Abstract: In an apparatus for manufacturing a plastic hollow body which hollow body is open on one end and closed on the other, for the forming of a head piece a withdrawal device rests on a ring-shaped nozzle having a ring-shaped nozzle having a ring-shaped nozzle opening, and for the forming of a plastic tubular segment the bottom elements of blow-mold pieces rest on the ring-shaped nozzle, to provide for blow-molding of the tubular segment by blow means. It is desired to be able to produce a hollow body with a closed head piece and a perforated bottom member. This is achieved in that the withdrawal device is configured for forming a head piece which is closed to the exterior; in that the bottom elements of the blow mold which rest on the ring-shaped nozzle forms a perforation in the bottom member of the body part of the hollow body, which perforation extends over the region surrounded by the ring-shaped nozzle opening; and in that the blow means disposed in the ring-shaped nozzle is associated with or "operative through" the perforation in the bottom member of the body part of the hollow body. Thereby, a hollow body can be manufactured which has a closed head piece and is fillable via the open bottom member.

Abstract: In speech recognition, speech values obtained from values sampled from a speech signal are compared with reference values, the words of a predetermined vocabulary in each case being specified by a sequence of reference values. The words are specified in terms of phonemes in accordance with a previously specified dictionary of pronunciation and the reference values for the phonemes are determined in a learning phase, each phoneme within a word consisting of a number of similar reference values, this number having been determined in the learning phase. To approximate transitions between phonemes, each phoneme can also consist of three segments each of constant reference values. The predetermined number of reference values per phoneme permits improved simulation of the time duration of a phoneme within a particular word. Various possibilities are specified for determining the reference values and the distance value in the recognition process.

Abstract: A phase comparator accepts two streams of digital pulses, one being a reference signal and the other a test signal, and generates an output signal indicative of the phase difference. The phase comparator can be implemented as a four-state device or higher, and thus exhibits a wide phase capture range, i.e. multiples of 360°, and can provide a stable, predictable and linear output signal when the two input signals are in lock. It is therefore very suitable by use in a phase locked loop in which temporary wide variations in phase can occur.

Abstract: An improved means and method is described for forming a Schottky diode integrated with transistors and other devices which is particularly useful where both control circuits and a large power device are on the same chip. 
     Nested N- (6), P- (8), N- (14) and P+ (26-30) regions are formed on an N+ semiconductor substrate (5). A portion (45H) of the overlying dielectric (45) is removed adjacent one of the P+ regions (28, 29) over the N- region (14) and a Schottky contact (54C) formed to the N- region (14) and an ohmic contact to the adjacent P+ region (28-29). N+ (34, 36) and P+ (26, 30) regions are desirably provided where the junctions between the N-(14) /P-(8) regions and the P-(8) /N-(6) regions intersect the surface to provide contact to the N-(14) and P- (8) regions respectively.

Abstract: Disclosed is an automatic travelling apparatus which permits: determination of a permissible travelling area on the basis of images taken by an image pickup device or video camera, showing the sight of the area appearing ahead of the vehicle; steering control of the vehicle to go into a target course in the permissible travelling area; and selection of a predetermined way of a selected crossing or branch in the target course. These complicated determination and control can be easily performed without fail. 
     Also, when an image pickup device or video camera take images of the area extending ahead of the vehicle for determining a permissible ravelling area, a wide-­angle camera, a telescopic range camera and an ordinary camera are selectively used to meet particular situations for example, taking pictures of a crossing, zigzag way or straight long way. This selective use of cameras of different characteristics permits correct identification of particular roads with those stored in the map storage.

Abstract: Provided is a process for precisely forming a Schottky barrier gate on GaAs. In the process, a layer of polyimide is spun onto a doped GaAs substrate having a passivating layer thereon. A resist layer is then spun onto the polyimide, and either deep ultraviolet lithography in conjunction with a clear field mask, or direct electron beam exposure, is used to define a gate region. After exposure, the resist is developed, leaving the unexposed portion of the resist in place on the polyimide layer. A metal transfer layer is then deposited over the structure, and the remaining resist is dissolved leaving a hole in the metal transfer layer. The polyimide and the passivating layer are etched down to the surface of the substrate through the passivating layer. The substrate is then dry etched, and then wet chemical etched to form a recess for the Schottky gate. The Schottky gate metal is deposited onto the surface of the structure and through the hole onto the substrate. The polyimide is dissolved and the upper layers lifted off leaving the Schottky metal gate deposited in the exposed recess in the GaAs substrate.
