Title: Arrangement of a semiconductor component suitable for surface mounting and a method for the surface mounting thereof on carrier plates
Inventor: MAIWALD WERNER
IPC: H01L23/50
Filed: 1990-01-25
Abstract: ABSTRACT OF THE DISCLOSURE         A semiconductor component is provided in an arrangement suitable for surface mounting on a carrier plate.  With the semiconductor arrangement, there is an exclusive holding of the terminal tapes by a semiconductor chip itself so that the previously-standard frame can be eliminated.  In addition, the ductile terminal tapes are angled off by 90° relative to a principal face of the semiconductor chip so that a significantly smaller structure and a higher packing density are possible in comparison to previously known and standard TAB versions.  For surface mounting of the semiconductor arrangement, the semiconductor chip is put in place on the carrier plate, as a result whereof the ductile terminal tapes deform and a reliable contacting to terminal areas on the carrier plate is guaranteed.          The surface mounting is possible with additional SMD installations.

Abstract: ABSTRACT A  distribution  class  recloser  comprises  puffer  type, compressed gas circuit interrupters and a spring stored energy operating mechanism.   The interrupter includes a single pair of elongated and axially aligned contacts, one of which is moveable and  includes  a  plurality  of  flexible  contact  fingers  for engaging the stationary contact.   The contacts include arcing tips  formed  on the  terminus portions  thereof  for  conducting arcing  current.    Additionally,  the  contact  fingers  on  the moveable  contact  include  raised,  wedge-shaped  electrical connections.   When the moveable contact engages the stationary contact, the raised connections flex the fingers outward so as to cause the arcing tips of the moveable contact to move out of contact  with  the  stationary  contact  to  allow  the  raised electrical connections to carry the continuous current.  It has been found that an interrupter of this design in which the same set of contacts carry both the arcing current and the continuous, steady state current may be made smaller, lighter in weight, and less costly, and thus can be employed in an recloser application and actuated  by  means  of  a  spring  stored  energy  operating mechanism.  The operating mechanism employs opening springs and closing springs  for actuating the interrupters by means of a mechanical  linkage and actuator shafts,  one of which extends through the housing of each interrupter.  A modular rotary seal assembly is also provided which provides both a bearing and a seal for the actuator shafts and which employs no metal-to-metal components.

Abstract: A delay circuit includes a memory addresses of which is designated by a counter incremented in response to each clock signal from an initial value set by an initial value setting circuit to an end value. A digital signal is written into an address as designated and read and converted into an analog signal to be outputted at an output terminal through a buffer amplifier. A delay time is determined by the writing timing and the reading timing of the digital signal. If the delay time is to be varied in the course of a delaying operation, a further initial value is set in the counter. A control signal for returning the counter to the initial value is generated by a first signal generating circuit when the end value is reached and a setting completion signal is generated by a second signal generating circuit when a setting of the further initial value is completed, and in response to both the signals, a muting signal is generated by a muting signal generating circuit, whereby the buffer amplifier mutes the output signal in response to the muting signal to prevent a noise due to random data from occurring at the output terminal.

Abstract: An information recording and reproducing device has a first recording-clock-generation circuit which generates a clock based on pre-recorded information on a magneto-optical disk, a second recording-clock-generation circuit, and a switching circuit. The switching circuit selects a first recording clock when recording is of discrete information, and selects a second recording clock when recording is of successive information. Moreover, in the present device, a first reading clock as well as a second clock are used as a clock for reading out the reproduced data from the magneto-optical disk. The second reading clock having a reference frequency is generated by a second reading-clock-generation circuit, and is used for reading out successive information such as music information. The first reading clock insynchronization with the reproduced signal is generated by a first reading-clock-generation circuit, and is used for reading out discrete information such as computer-use data. In addition, in the case of discrete information, it is possible to start a recording/reproducing operation immediately after an optical head reaches a desired position, thereby permitting a shortened access time.
