Abstract: A pair of elongated rectangular metallic bumps are formed on two separate surfaces. The bumps are aligned orthogonally prior to being merged by hybridization to form a high density hybrid assembly. Translational misalignment does not change the interconnect area. Rotational misalignment causes only a slight change in the interconnect area. The bump surface area is increased by merging the bumps. This reduces the hybridization pressure which prevents the interconnect area from increasing in size, commonly known as mash out. The invention makes high density hybrid assemblies practical because it reduces the risk of short circuits between adjacent interconnects and results in a high yield in production.

Abstract: An approximate reasoning apparatus converts input data into a degree of membership by a membership function, obtains an information quantity for each of a number of factors using the degree of membership, and obtains the possibility of a conclusion using the degree of membership and the information quantities. As a result, the accuracy of an information quantity which prevails at the moment data is entered is taken into consideration to obtain results of reasoning having a high identification capability. Further, a static information quantity of each factor is calculated, the clarity of each factor is obtained from the static information quantity, the clarity of a factor for which data has been entered is calculated from the clarity of each factor, and the finally calculated clarity is displayed as clarity regarding results of reasoning. This makes it possible to judge the reliability of the results of reasoning from the displayed clarity.

Abstract: In the semiconductor integrated circuit, the data delay circuit (9) and data latch circuit (10) are connected between the sense amplifier circuit (7) and the output buffer circuit (8). A pulse signal for controlling the output buffer is first generated according to a pulse output signal of the address change detection circuit (12), and then a latch signal which permits output data of the data detection circuit (7) obtained before the change of the address input signal to be latched by the data latch circuit for a preset period of time is generated. Next, a delay signal is generated which sets the delay time of the data delay circuit to be short in a case where data detected by the data detection circuit is not output from the output buffer circuit, and sets the delay time of the data delay circuit to be long in a case where data is output from the output buffer circuit. Generation of the delay signal is interrupted after the pulse signal of the address change detection circuit is interrupted. As a result, the power source variation at the time of output data change or erroneous operation due to noise input from the exterior can be prevented. Further, the driving ability of the output buffer transistor can be set to a large value so that a highly reliable semiconductor integrated circuit in which the operation margin of the integrated circuit with respect to the power source variation and noise can be made large while keeping the data readout speed high can be obtained.

Abstract: Disclosed is a method for recovering data from a portion of a magnetic surface that contained a read error. After a read error is encountered a magnetic transducer undergoes a head state change. The head state change is accomplished by either writing (64) to a reserve area of the magnetic surface and or reading a portion of the magnetic surface and then rewriting to that portion of the magnetic surface. After the magnetic transducer undergoes a head state change, the portion of the magnetic surface that contained the read error is reread (68).

Abstract: Apparatus for detection of laser output on a semiconductor wafer, wherein the laser and detector can be formed by similar or simultaneous processes on the same semiconductor substrate. More particularly, a laser cavity and a detection cavity (13, 19) are formed on a semiconductor wafer (11) in parallel, such that light emitted laterally from the laser cavity is detected by the detection cavity. The amount of light detected can then be transformed into data, which in turn can be used to control the output of the laser. Advantages of the present invention include the ability to simultaneously form the laser and detector portions. The detector portion does not interfere with the beam being provided by the laser, and multiple laser-sensor pairs can be integrated on a single semiconductor substrate.

Abstract: An improvement in a light emitting device is disclosed comprised of an image display array consisting of a plurality of light emitting pixels arranged in intersecting columns and rows. The pixels are each located on a common electrically insulative light transmissive support with pixels in the same column including a common light transmissive first electrode element located on the support. An organic electroluminescent medium overlies the first electrode elements. The pixels of each row include a common second electrode element located on the organic electroluminescent medium. The light emitting device is fabricated by providing the support with the first electrode elements positioned in laterally spaced columns thereon to form a supporting surface, depositing the organic electroluminescent medium on the supporting surface, and forming the second electrode elements on the surface of the organic electroluminescent medium. 
     A series of walls of a height exceeding the thickness of the organic electroluminescent medium are formed at common boundaries of the pixels in adjacent rows prior to depositing the organic electroluminescent medium. A source for the vapor phase deposition of metal forming the second electrode elements is oriented relative to the support at an angle that interposes each wall between the source and an adjacent portion of the surface of the organic electroluminescent medium and, the metal forming the second electrode elements is selectively deposited on the surface of the organic electroluminescent medium in areas other than those in which the walls are interposed between the source and the surface of the electroluminescent medium.

Abstract: The application relates to an information transfer system, comprising a receiver (3) and a transmitter (1) for transferring an information signal to the receiver (3)  via  a transfer medium (2). The information signal comprises main data and sub data. The sub data comprises coded text lines having a plurality of character codes. The receiver is provided with a character display unit (10) for displaying characters corresponding with the character codes in the coded text lines. The number of character display positions is less than the number of character codes in the coded text line. The receiver is provided with display control means (9) for controlling the display of characters corresponding to the character codes included in the coded text line in dependence on serial control codes included in the coded text line. The system enables that significant parts of the text information available in the sub data can be shown on both a full multi-line display units for displaying full text lines and a 1-line display with a relative small number of digits. The invention is very suitable for systems with small sized receivers, such as e.g. portable players and car radios, and receivers wit a display on its remote controller, because there is not much space available for a display unit.
