Patent DE-2213362-B2 (DE)
Title: Semiconductor component with disc shaped chip - has two zones with different impurity concentration, each of specified dimensions and configuration
IPC: H01L21/00
Filed: 1972-03-20
Abstract: Between two zones of different impurity concentrations is formed a pn-junction, which encloses with the outer surface of the semiconductor body a sharp angle at the side of the higher impurity concentration. In the zone of higher impurity concentration the latter is smaller at planes parallel to the pn-junction at the outer surface than inside of the body in the region of the barrier layer. In the higher concentration zone (2) the impurity concentration is smaller on planes (z), parallel to the pn-junction (1), into a depth of 50 microns from the oblique outer surface (4). Inside the semiconductor body on the same planes the impurity concentration is higher.

Abstract: The electromagnetically operated switching unit consists of movable spring loaded switching elements which are coupled to the armature of the magnet. The switching elements move in the same sense as the armature. There is also a fixed support for the fixed switching elements. The travel of each switch contact is limited and there is a flexible damping unit (20, 22, 23, 26) fitted in each case between the fixed contact carrier (12) and its supporting parts (12). The connection of the fixed contact carrier is via a bolt (20) passing through the body (14) of the support element.

Title: Air dryer for car wash - has swivelling overhead mounting of jets and blower to prevent body damage with pivot near centre of gravity
IPC: B60S3/00
Filed: 1972-05-24
Abstract: The car wash air drier has the air jet housing (3) and the blower motor (5) mounted as one unit on a pendant pivot (7) near the centre of gravity of the system so that in the free state the air jet is directed downwards. As a vehicle passes under the jet it pushes it aside gently to blow the airstream over the contours of the roof, windscreen and front and rear sides. The pendant mounting also ensures efficient clearing of steeply sloping and vertical sides. The jets are fitted with rollers (4) to prevent scratching of the bodywork, if the air blower fails. Under normal conditions the reaction of the airstream on the car roof is sufficient to lift the mouth of the nozzle clear off the body. Accurate balancing of the system is obtained by an adjustable counterweight (6) on the motor.

Abstract: The watch comprises an oscillator, a frequency divider, display means capable of displaying at least hours and minutes, and a correction circuit controlled by a rotary time setting stem which is capable of assuming at least two axial positions, one being a rest position which is occupied by the stem when the watch is functioning normally and an operative position for jointly correcting the minutes display and the hours display. The correction circuit is so arranged as to provide for correction of hours display alone in response to a particular rotary movement of the stem in its rest position. This particular rotary movement may comprise, in regard to the stem, rotating at least through a minimum angle in a time interval which is less than a predetermined period, for example at least two revolutions in less than two seconds. The minutes and hours displays are changed and the hours display is corrected in the forward direction or the backward direction depending on the direction of rotation of the stem.

Patent JP-H0730657-B2 (JP)
IPC: E06B1/32
Filed: 1987-02-24
Abstract: The composite laminate is made of two metal parts 1, 2 and a pair of thermal insulating bars of fiber reinforced synthetic material. Each metal part has a longitudinally extending groove which is provided with two rows of transversely disposed teeth which cut into the flanks of anchoring strips on the synthetic bars during pressing in of the strips in the respective grooves. The pressing in of the synthetic material into the teeth of the harder metal parts forms a strong bonded connection which resists the stresses imposed upon the laminate during use. Deformable tabs on the metal parts are used to ensure locking of the synthetic bars in place. The space required for production of the laminate is reduced essentially to the length of the metal parts.

Abstract: PURPOSE: To improve the security of the system while using the system by making the system to be discriminated whether the inputted voice is the natural voice of a registered user or a recorded voice or a synthesized voice in the device which uses a text specifying type speaker collating method. CONSTITUTION: During a speaker registration, the device side arbitrarily decides two kinds of specified texts. Then, a code book corresponding to each text is produced for every speaker and is stored in a code book storage section 18. During a speaker collation, a user is asked to pronounce text voices corresponding to the two specified texts. Then, the features of the inputted voices corresponding to one of the specified text are quantized by the code book for every speaker corresponding to the texts. After that, distortion distance in the speaker is obtained and a relative threshold value, which represents whether it is a natural voice or not, is determined from the feature difference of two voices and the distance between the code books. Then, the in-speaker-distortion distance and the relative threshold value are compared by a comparison section 15.  If the distance is larger than the value above, it is judged to be other than a natural voice and the processing in the speaker collation section 16 is made prohibitive.

Abstract: The image quality obtainable by an electrographic copying process in which an electrostatic latent image formed by imagewise exposure of a uniformly charged photoconductive layer, or otherwise, is developed with a toner can be improved if the latent image comprises discrete charge bearing zones, preferably formed by a supplementary exposure through a half-tone screen, and if additionally the toner is electrically conductive either intrinsically or as a result of electrical break-down. In this manner, the maximum density obtainable in a copy can be increased and the contrast decreased sufficiently to allow good reproduction of both continuous tone and high contrast images.
