Abstract: A recording/reproduction system performs high precision drop-out processing and compensation in the reproduction mode from a diskshaped recording medium (1) by using a recording format in which a video signal is divided alternately in units of one horizontal scan line into two channels, and the timing of the recorded video signal on one channel is displaced relative to that of the other channel, so as to record the divided signals on a pair of parallel spiral tracks (CH-1, CH-2) forming the two channels on the disk (1). A mean value interpolation circuit is provided in each channel for drop-out compensation, and a portion of a reproduced signal of one channel is compensated by a compensation signal produced by the interpolation circuit of the other channel.

Abstract: The present invention relates to a novel process for making a macrocomposite body. Specifically, a metal matrix composite body is first formed and thereafter, a ceramic body or a ceramic matrix composite body is caused to form from at least one surface of the already formed metal matrix composite body. The ceramic or ceramic composite body can be formed by, for example, changing from spontaneous infiltration conditions which permit a molten matrix metal to infiltrate a filler material or preform to conditions which favor the growth of a ceramic oxidation reaction product from the matrix metal (e.g., the matrix metal serves the dual role of a matrix metal and a parent metal for growth of oxidation reaction product). The growth of oxidation reaction product can occur from one or more surfaces of a metal matrix composite body and can be controlled to result in any desired shape. Moreover, the oxidation reaction product can be caused to grow directly into an atmosphere to form a ceramic body or can be caused to grow into an adjacently located filler material to form a ceramic matrix composite body. The oxidation reaction product can be formed substantially immediately after the metal matrix composite body is formed or may be formed at any point later in time.

Abstract: The invention relates to a transmission system for transmitting packets which comprise an information word group and a control word group, the control word group comprising an identification of the packet type (such as an identification of the virtual transmission channel and/or of the group of virtual transmission channels via which the packet is being transmitted), which transmission system comprises access control means for granting or refusing packets access to the part of the transmission system situated downstream of the access control means, depending on the incoming volume of packets. The invention provides for recording packets not admitted to the downstream part (T) of the transmission system by the access control means (2, 3) by an error reporting device (4). Preferably, provision is made that the error reporting device (4) for the packets not admitted records the number for each packet type (vci), and moreover, that the error reporting device (4) delivers an error report (c4) as soon as the number of packets not admitted exceeds a particular threshold value for a packet type. <IMAGE>

Abstract: Data arranged in packets are transferred between a system memory and a network bus through a SRAM configured by software pointers as first in-first out memories for transmitting (transmit FIFO) and for receiving (receive FIFO). The packets of data stored in the transmit and receive FIFOs are demarked from each other and classified by tag and status bits at the end of the last word of each packet. Data to be transmitted on the network bus is transferred from the system memory to the transit FIFO, and data received from the network is stored in the receive FIFO. To maximize data throughput, when either at least a predetermined amount of data or a complete packet is stored in the transmit FIFO, the data is transmitted to the network while data is being received from the system memory. When at least a predetermined amount of data is stored in the receive FIFO, data is transferred to the system memory while network data is incoming from the network. One application of the invention is in a Fiber Distributed Data Interface (FDDI).

Abstract: The present invention relates to a newly identified family of protein serine/threonine kinases which phosphorylate microtubule-associated protein 2 (MAP2). It is based, in part, on the cloning and characterization of novel MAP2 kinases designated extracellular signal-regulated kinase 1, 2, and 3 (ERK1, ERK2, ERK3) which are expressed in the central nervous system, and on the identification of another ERK family member, ERK4, with antisera. The present invention provides for recombinant nucleic acid molecules and proteins representing members of the MAP2 kinase family, and also for microorganisms, transgenic animals, and cell lines comprising recombinant MAP2 kinase molecules. In additional embodiments of the invention, the present invention provides for methods for assaying cellular factor activity, including, but not limited to, nerve growth factor activity, in which the activation of MAP2 kinase serves as an indicator of cellular factor activity. These methods may be extremely useful in screening compounds for the presence of a desired cellular factor activity. In specific embodiments, compounds which may be useful in the treatment of Alzheimer's disease, peripheral neuropathies, and diabetes may be identified using the methods of the invention.
