Inventor: BURGER HANS-JOACHIM
IPC: B06B1/06
Filed: 1990-07-05
Abstract: In previous ultrasonic layered transducers, a piezo-ceramic element has two metallised side surfaces to which in each case one braided wire is soldered, small covering sheets (3) resting on the two side surfaces. In order to improve handling and simplify making of the contacts with the braided wires, grooves (4) for said braided wires are provided in the small covering sheets (3). The braided wires (1) project partially out of the grooves (4) by means of which they are positioned and are pressed through the small covering sheet (3) onto the metallised side surface in order to make contact. The use of solid conductors (1) rather than braided wires furthermore results, for example, in the advantage that the solid conductors (1) can project further, at a specific spacing, in order that they can be used either as ready-to-use plug connections or for soldering into a printed-circuit board. <IMAGE>

Filed: 1990-12-13
Abstract: A layer of a substance such as a metal, non-metal or metal alloy is deposited, preferably by sputtering, onto the surface of a substrate such as a semiconductor wafer (108). The adatoms of the deposited layer are mobilized by being bombarded with a flux of low energy neutral atoms or molecules at an oblique angle of incidence to enhance step coverage and/or planarization of the semiconductor wafer (108). The neutral atoms or molecules are formed within the plasma by applying a negative bias potential to a reflector electrode (118) which will attract positive ions from the plasma. The neutral atoms or molecules elastically scatter from the surface of the electrode (118) to bombard the adatoms being deposited during the operation of the sputter source (114).

A converging ultrasonic beam (B) is radiated against a point (P) on a surface of the ceramic (1), said point being a predetermined distance away from the join (3) between the ceramic (1) and the associated non-ceramic (2). Data on the intensities of interference waves at respective predetermined varia­tions of the relative distance between a probe (5) of the ultrasonic microscope and the ceramic (1) are col­lected. The residual stress at the point is calculated on the basis of the cycle of echo intensities of the interference waves for the respective predetermined variations of the relative distance. The strength of the join is then determined on the basis the residual stress.

Abstract: In a hydraulic pressure control valve for use with a master cylinder (81), a valve chamber (32) is formed at an attaching section (12h) of a valve body (12). An annular recess (33) is formed in the valve body at a location of an end of the stepped bore, which opens to the valve chamber. A valve element (40) is arranged within the valve chamber for movement therewithin. The valve element has a stud (44) which extends to an interior of the master cylinder and which receives, from the piston within the master cylinder, such a force as to cause the valve element to fall down. An annular preventing element (52; 201; 352) is formed separately from the valve element and the valve body. The preventing element is arranged between the valve element and the end of the stepped bore, which opens to the valve chamber. The preventing element substantially covers an annular end of the annular recess, which opens to the valve chamber, for preventing a seal element (26a) from coming out of the recess, which is arranged therewithin.

Abstract: The carriage guided on a stair rail is equipped with a solid catch lever (28) which is pivotably arranged transversely to the travel direction (32) so close to the stair rail that it can swing with its descent-side lever arm (39) against the action of a tension spring (34) into the area between two adjacent rungs (7) and (7a) which are arranged on the stair rail perpendicularly to the travel direction (32). The tension spring (34) attempts to move the catch lever (28) into a position pointing in the travel direction (32). On its longitudinal side pointing towards the stair rail, the catch lever (28) has on its ascent-side arm a lobe-like projection (45) which pivots the catch lever (28) during descending travel on each rung (7) in such a way that the descent-side arm of the catch lever (39) enters the intermediate space relative to the next rung (7). If the descending travel exceeds a predetermined speed, the catch lever (28), on account of its inertia, cannot escape quickly enough from the area of the rungs (7) and stops the carriage. <IMAGE>

Filed: 1991-05-07
Abstract: The image processing device finds core linear segments of a linework image by thinning processing; provides a mask area for each end point of the linear segments; integrates the mask areas overlapping with each other into a sum area; with respect to each sum area, finds effective linear segments which have only one end point within each sum area; and judges a feature point in each sum area according to the number of the effective linear segments. Therefore, the device is advantageous in that the feature points are classified more accurately because the linear segments irrelevant to judging the feature points (such as those produced due to distortion and line missing) can be eliminated in the judgment. It is also advantageous in that the data amount to be handled is small and classifying is completed at a high speed since the feature points are classified after vectorization of raster data.

Abstract: An integrated circuit having a normal operating mode and a special operating mode, such as a special test mode, is disclosed. The special test mode is enabled by a series of signals, such as overvoltage excursions at a terminal, rather than by a single such excursion, so that it is less likely that the special test mode is entered inadvertently, such as due to noise or power-down and power-up of the device. The circuit for enabling the test mode includes a series of D-type flip-flops, each of which are clocked upon detection of the overvoltage condition together with a particular logic level applied at another terminal; multiple series of flip-flops may be provided for multiple special test modes. Additional features include the provision of a power-on reset circuit which locks out the entry into the test mode during power-up of the device. Acknowledgment of the entry into test mode is provided by the presentation of a low impedance at output terminals while the device is not enabled; chip enable of the device causes the device to exit the test mode. Once in test mode, the output enable terminal of the device can provide a chip enable function.

Abstract: Amplifying elements of a final stage circuit are biased in definite voltage, and amplifying elements of a drive circuit are biased in variable voltage. Then amplifying elements of the final stage circuit are operated at the operation point to enable the class "AB" amplification where the power efficiency and the linearity are compatible, and bias of amplifying elements of the drive circuit is made variable thereby the power gain may be varied at a wide range. The high frequency power amplifier circuit is constituted by multiple stages comprising the final stage circuit and the drive circuit, and amplifying elements of the final stage circuit are constituted by GaAs FET and amplifying elements of the drive circuit are constituted by enhancement type MOS transistor, so that even in super high frequency band of quasi SHF class, while the good amplification characteristics and the power efficiency are secured, the high frequency output power can be variably controlled in a wide range using system capable of being realized simply. Accordingly, without controlling the bias voltage having opposite polarity of the operation source voltage, the power gain of the whole high frequency power amplifier circuit can be varied in a wide range.
