Title: Time division exchange for carrying out a loop-back  test
Inventor: KAWAGUCHI TOMOHIRO
IPC: H04J3/06
Filed: 1985-08-14
Granted: 1988-04-26
Abstract: ABSTRACT     A time division exchange interchanges predetermined time slots of a time division multiplexed signal and returns it to a network during a loop-back test.  A buffer memory in a time division multiplexed trunk is used to interchange the predetermined time slots.  Alternatively, the buffer memory is provided in a return loop for use during the loop-back test.          Therefore, it can be determined that the received signal is sent from another exchange and the loop-back test can be performed using ordinary exchanging processing procedures.

Abstract: A B S T R A C T     A fiber optic coupler easily molded as an optically transparent body and adapted to provide bidirectional transmission, multiplexing, demultiplexing, fail safe relaying, or other functions from a single coupler. The body may be molded without side actions for simplicity and accuracy of placement of critical surfaces. The body includes first and second cavities for positioning light sources, such as a solid state emitter or fiber termination, and third and fourth cavities for positioning a light receiver, such as a solid state detector or fiber in a fiber connector. Opposite each source and receiver cavity is located a reflector cavity terminating in a reflecting face formed by the air-coupler body interface and operating by total internal reflection. A slot extends into the body to position a filter such as a dichroic mirror or beam splitter between the cavities. The filter, source and receiver cavities, and reflecting faces are positioned to provide light paths from one or both sources, reflected by the associated reflective face, and passing through or reflecting off the filter. The transmitted or reflected light is then reflected off one or both of the remaining reflective faces to one or both of the receiver cavities. The reflective faces may spherical, aspheric concave, ellipsoidal, paraboloidal or flat.

Abstract: ABSTRACT The present invention relates to a digital signal repeater of the type in-cluding a controller for controlling activation/non-activation of a radio trans-mitter.  The repeater has an improved controller to avoid activation by inter-ference signals as well as a receiver.  The controller is responsive to the out-put of the receiver for providing a control signal controlling the transmitting operation of the transmitter.  The controller comprises a first decision circuit for detecting the level of the modulated carrier wave of an intermediate fre-quency band of the receiver and providing a first signal, a second decision cir-cuit for detecting a clock frequency component in the output of the receiver and providing a second signal, logic circuitry responsive to the first and second signals for providing a third signal, a circuit for smoothing the third signal, and a comparator circuit for comparing the output of the smoothing circuit with a reference level and providing the control signal.

Abstract: ABSTRACT OF THE DISCLOSURE         In an information recording medium having a recording layer for recording information by heating through incoming energy, at least one of an interference layer and an absorption layer for the incoming energy is provided on the energy-incoming side of the recording layer to reduce the reflected energy from the information record-ing medium and increase the quantity of heat input into the recording layer.  The temperature of the recording layer is rapidly enhanced, and rapid writing is made possible thereby.  Writing or erasing can be made with less incoming energy, and thus the writing sensitivity or erasing sensitivity of the information recording medium can be increased.

Abstract: ABSTRACT An internal combustion burner system includes a combustion chamber that has spaced plate type sidewalls and peripheral wall structure secured to the sidewalls. Housing structure surrounds and cooperates with the peripheral chamber wall structure to define flow paths that extend around the perimeter of the combustion chamber.  An air-fuel mixture is fed through a housing inlet and along the perimeter flow paths for cooling the peripheral wall of the combustion chamber and then into the combustion chamber through flame stabilizer ports. The air-fuel mixture is burned in the combustion chamber, and the resulting combustion products are discharged from the chamber in one or more high velocity jets.  During burner operation, the uncooled combustion chamber sidewalls are typically red hot and flex to accommodate thermal expansion forces while the peripheral walls of the chamber provide a stable peripheral frame that is regeneratively cooled by the air-fuel mixture.

Abstract: Abstract A guide bar for a saw chain of a motor-driven chain saw has a guide groove formed in the periphery thereof.  The drive links of the saw chain have projections known as rakers which protrude beyond the side links of the saw chain and which are guided in the guide groove.  The guide bar has at least one supply bore in a groove wall through which lubricating oil is supplied for lubricating the saw chain.  In the vicinity of the supply bore, a lubricant surface extending approximately parallel to the groove bottom is provided.  This lubricant surface extends to at least one supply surface extending as far as the supply bore.  The rakers of the drive links move above the lubricant surface with a narrow spacing.  The lubricating oil supplied via the supply bore is guided via the supply surface to the lubricant surface where it forms a film into which the rakers extend as the saw chain revolves.  This assures that the supplied lubricating oil is picked up by the rakers and carried by them to the link locations of the saw chain thereby assuring very effective lubrication.

Abstract: Abstract of the Disclosure A sync separator detects the occurrence of a corresponding sync pulse in a corresponding part of the waveform of a composite video signal.  The level of the sync tip is used for updating a sync tip signal, provided the level of the sync tip is lower than that of the sync tip signal.  A time-out signal is generated at the end of a time-out interval that has elapsed from the last time the sync tip signal was updated, provided the sync tip signal was not updated within such time-out interval.  The time-out signal is used for updating the sync tip signal. The sync tip signal is updated according to such sync pulse that occurred during the time-out interval, having the lowest level sync tip.  Information obtained from the sync tip and the back porch portions of the corresponding sync pulse is used for generating a slice level signal.  A comparator responsive to the slice level signal separates a sync signal from the composite video signal.
