  • Patent number: 5453568
    Abstract: An indication or image on a display unit is switched in response to changes in performance data of a tune which is being played automatically. Tone pitch data included in the performance data are detected, and the indication on the display unit is switched in response to changes in the detected tone pitch data. Velocity data and tone color data in the performance data may be used in place of the tone pitch data. If a tune is automatically played based on a plurality of performance data which are simultaneously read out, the indication on the display unit is switched based on changes in either of the plurality of performance data. If switching data representing changes of rhythm of the tune is included in the performance data, the switching data are detected, and are used to change a way of switching the indication (image) on the display unit. The indication or image on the display unit may be switched at timings based on beats or strong beats or at timings of measures.

  • Patent number: 5449949
    Abstract: A monolithic integrated semiconductor is proposed, in which on the main surface of a monolithically integrated n-p-n transistor or p-n-p transistor, a cover electrode (D1) is mounted for internal voltage limitation, covering only a single junction region between a highly doped zone (5) and the weakly doped substrate (1). An adjacent highly doped zone (4) is not covered by the cover electrode (D1). By connecting the metal cover electrode (D1) to the pickup (12) for a voltage divider (R1, R2), a breakdown voltage can be adjusted that is higher than the sum of the depletion breakdown voltage and the enhancement breakdown voltage.

  • Patent number: 5448561
    Abstract: An improved method for exchange of data in data processing installations, especially Controller Areas Networks (CAN), permits acknowledged and segmented transmission of data strings, of arbitrarily long length, between at least two stations in the network or other data processing installation. The method includes the transmission of the messages associated with the data by means of frames; the frames contain a header field and a data field. In the event of contention between multiple stations of the data processing installation for access to the bus connection, which frame has priority is determined by evaluating the respective header fields. In the data field of the frame, there is a control information field (58, 95) containing a message code which serves to identify the message type. The message codes distinguish among activation messages (AR, AC), data messages (DT), and acknowledgement (AK) messages. This permits transmission of data strings, of limited length, with acknowledgement.

  • Patent number: 5447162
    Abstract: An electronic Sphygmomanometer employing both the Korotkoff method and the oscillometric method which is thereby capable of accurately measuring blood pressure due to the advantages of the two methods. The electronic sphygmomanometer is arranged in such a manner that either of the results of measurements of the two methods can be automatically selected. A gate for detecting the Korotkoff sound by using an oscillation in cuff pressure is automatically stopped, and the validity of the Korotkoff sound is determined in accordance with a change in the height of the oscillating pulse wave.

  • Patent number: 5446332
    Abstract: Several exemplary embodiments for an ultrasound transducer are suggested, in which the sound propagation in the vertical plane is narrow-angled and in the horizontal plane wide-angled by means of appropriate damping measures. The effect on the propagation characteristic is achieved by means of the embodiment in accordance with the invention of the oscillating diaphragm and/or the housing, as well as multiple disposition of piezo oscillators. Because of these measures, damping of the sound waves or the sensitivity of the sensor is approximately the same over the entire horizontal angle up to almost 180.degree..

  • Patent number: 5446909
    Abstract: Binary multiplication is performed with existing data processing apparatus to which only minor modifications are required. One operand and a partial product are stored in existing latches of a CPU. The second operand is stored in a shift register which is added to the CPU. The data in the shift register is shifted from the LSB to the MSB, with a "0" being loaded into the LSB. As the bits in the first operand are designated in sequence, the value of the partial product is increased by the value in the shift register if the designated bit is a "1". After the sequencing has designated all the bits of the first operand, the partial product is taken to be the product of the multiplication.

  • Patent number: 5446341
    Abstract: To provide a tight seal between an essentially solid niobium or tantalum necting pin or rod (10) passing through an opening (7, 28) in an end plug (11) closing off a high-pressure discharge lamp discharge vessel (8), the pin or rod is formed with two axial portions, one of which has externally projecting continuous rings (17), preferably two or three, or an externally projecting thread (26). The rings or thread are press-fitted into the end portion of the bore in the plug, which deforms the edge (20) of the rim, ridge or thread, or shears off the edge portion, ensuring a tight preliminary fit in the bore; sealing glass, which is then melted to fill a capillary space between the pin or rod and the plug, is protected by the preliminary seal against corrosion or attack from the fill within the discharge lamp; if the projection is in form of a thread, glass can penetrate within the threads to further seal and retain the pin or rod.

  • Patent number: 5444908
    Abstract: A die assembly for driving a pierce nut which comprises an annular coining portion provided on the top of a die body, the inner surface of the annular coining portion being continuous with a center aperture of the die body. An annular projection is provided at the upper portion of the center aperture for surely and temporarily holding punched debris in of the die body, near the annular coining portion, the center aperture. It is therefore possible to provide an inexpensive nut-driving die assembly with improved durability, and which can prevent debris, punched by shearing between a pierce nut and a metal panel and remaining at the upper portion of the center aperture, from being lifted up when the metal panel is lifted from the die body, thereby ensuring a continuous driving work.

  • Patent number: 5444742
    Abstract: A system is proposed for bidirectional electromagnetic transmission of data signals between at least two stationary units and one vehicle unit. The stationary units in the downlink mode synchronously transmit the data signals to the vehicle unit and have different carrier frequencies. In the uplink mode, the data signals are transmitted from the vehicle unit to the stationary units by the semipassive transponder principle. In the process, the data signals of the vehicle unit are frequency-modulated to the various carrier frequencies of the stationary units. This arrangement improves the reliability of bidirectional data transmission. A preferred application is data exchange for traffic control systems between stationary beacon units and moving vehicles.

  • Patent number: 5444553
    Abstract: An image data processing apparatus binary-codes an image signal obtained from an image sensor of the CCD type or the like so as to output a binary-coded image signal. The image signal obtained from the image sensor A/D-converted into digital image data. Based upon the digital image data, average values of luminance values of the digital image data are calculated for an array of pixels in a preselected area of the CCD. This average value is used as a threshold level for binary coding the image data for these pixels at the center portion of this preselected area. Furthermore, to detect coutours this data processing apparatus calculates a gradient in the luminance values of the pixels in a portion of the preselected area of the CCD in an X direction and a Y direction, and the gradient value is used to obtain binary-coded data in accordance with the above-described method.
