Patent EP-0363163-A2 (EP)
Inventor: TANAKA YUTAKA
IPC: H01L21/027
Filed: 1989-10-04
Abstract: An X-ray exposure apparatus for exposing a semiconductor wafer to a mask with X-rays, to print a pattern of the mask onto the wafer, is disclosed. The ambience within a stage accommodating chamber, accommodating a mask, a semiconductor wafer and the like, is replaced by helium and, thereafter, a predetermined quantity of helium is supplied into the stage accommodating chamber. This effectively prevents degradation in purity of helium due to air leakage into the chamber and, therefore, undesirable decrease in quantity of X-ray transmission can be avoided. Thus, high-precision and high-throughput exposure is ensured.

Abstract: In order to achieve constantly perfect, near-stoichiometric combustion with extremely low power consumption and virtually silently in spite of the continually varying atmospheric conditions, only that amount of air absolutely necessary at one time for the combustion, depending upon the amount of fuel fed in, is fed to the atomising region of an ultrasonic fuel atomiser (10) in a controlled and precisely metered manner. The air fed in in this way is mixed, in the fuel-outlet region of the fuel atomiser (10), with the fuel atomised in this way, and this mixture is burnt in an adjacent combustion chamber.

Abstract: The barrel has a number of independently controlled resistance heaters with their conductors packed in insulation; these heaters are pressed down on to the elasticating barrel by means of split collars and tangential grips. Holders engage the device to carry the plasticising unit when it is being changed; another device cuts off the unit in a stable equilibrium position when disconnected from the injector. The resistance heaters are spiral, flat and tubular and under the pressure of the collars; at the ends of the spirals where they are free from heater windings the individual wires are brought out and they are covered with a U-shaped protective section. This section is a support member.

Abstract: In a brake circuit with a mechanical brake pressure control device and an electrical brake pressure control device, the mechanical brake pressure control device serves to ensure emergency operation in the event of a fault in the electrical brake pressure control device which has overriding control in normal operation. The brake circuit can be controlled as a function of the load only when both the mechanical and the electrical brakes control device pressure contain a load-related brake pressure regulator. Such a solution is costly. 
<??>In order to reduce this cost, the invention proposes to provide a retaining device (3) in the mechanical brake pressure control device (3, 5) which transmits the brake pressure set in the mechanical brake pressure control device (3, 5) only in the event of a fault in the electrical brake pressure control device (6, 9, 12, 13). As a result the electrical brake pressure control device (6, 9, 12, 13) is available without the need for a load-related brake pressure control in the mechanical brake pressure control device (3, 5) of a load- related brake pressure control system. 
<??>The preferred sphere of application of the invention is motor vehicle brake systems.

Abstract: A manufacturing method of structural parts for wearing products is described which allows partial webs having one concavoconvex edge to be attached to other parts of the product in a high speed process of manufacturing these vearing products. A concavoconvex cutting line (33) is applied in the longitudinal direction of a first web (30) to form first and second partial webs (30a,30b,130a,130b). The first partial web (30a,130a) is offset with respect to the second partial web (30b,130b) in the longitudinal direction thereof by a prescribed interval, so that the concave edges and the convex edges (33a,33b) of the first and the second partial webs (30a,30b,130a,130b) are positioned opposite and aligned to each other respectively. Thereafter the wearing products are manufactured with these partial webs arranged on the outsides thereof.

Abstract: A predefined character is transmitted by a central DTMF transmitter for a short time for a specific telephone terminal in response either to an automatic prompt (Voice Mail System) or to an operator instruction. This character is identified in the evaluation device in the telephone terminal and is converted, following decoding, into a signal which serves to activate a secondary control circuit. In order to display the "message waiting" user facility, a luminous element (light-emitting diode Led) is activated in such a case via a memory circuit (bistable element BK1) by a continuous signal generated as a result from the short-time DTMF signal. <IMAGE>

Abstract: Method and apparatus for converting multibit pixel data to a lesser number of bit pixel data and re-expanding the compressed data. Luminance data for each pixel is established as the 5 most significant bits of the original luminance signal. The chrominance information for groups of pixels is subsampled, and a common chrominance value assigned to each of the pixels in a group. The resulting compressed pixels may be 8 bits wide providing economical possibilities to store the 8 bit wide data. The data is expanded for display by adding lower order data bits to the compressed luminance signal data bits. A subsampled chrominance data signal is appended to the expanded luminance data for display.

The finished tubing (12) with an expanded diameter on one end and a non-expanded diameter on the other end is then removed from the mandrel (14), and is ready for use. Untapered tubing (12) can also be radially expanded by this method to provide a thinner wall.

In the non-actuated (OFF) position the keys are substantially flush or slightly proud of the top surface (1a) of the housing, but when the keys are depressed they descend beneath the top surface (1a). The apertures (2) or the keys (3) (or both) have chamfered walls, the angle of chamfer being at least 4° and preferably 7°-10°. This prevents the keys from jarring or sticking against the walls of the apertures, enabling them to return to the non-actuated position without difficulty.

Abstract: On recognizing first through P-th input patterns as first through P-th recognized patterns (P being greater than one) by using a plurality of reference patterns and a plurality of memorized identifiers identifying the reference patterns, a processing circuit (35) processes the first through the P-th input patterns into first through Q-th provisional patterns different from one another, where Q is not greater than the above-mentioned plurality. A calculating circuit (50) calculates dissimilarity degrees had by the reference patterns relative to the first through the Q-th provisional patterns to select, with repetition allowed as selected patterns, the reference patterns which have the dissimilarity degrees less than a predetermined degree. The calculating circuit thereby selects R particular identifiers and S different identifiers from the memorized identifiers, where R plus S is not greater than P and is not less than the plurality. Each particular identifier and each different identifier identify only one pattern and one of at least two patterns of the selected patterns. The other at least one of the above-mentioned at least two patterns is identified by at least one of the R particular identifiers. A determining circuit (60) determines first through P-th output identifiers identifying the first through the P-th recognized patterns by using the R particular idenifiers as ones, R in number, and others, S in number, of the first through the P-th output identifiers.
