Abstract: An electrical circuit system having a semiconductor device (14) 
electrically and thermally connected to an electrically conductive 
circuit layer (16) of a substrate (12) and having a heat-dissipating base 
layer (18) of an aluminum metal material in the substrate has an 
electrically insulating hard coating dielectric layer (20) of aluminum 
oxide directly adherent to the base layer mounting the 
electrically conductive circuit layer thereon in selected 
electrically insulated relation to the base layer while providing 
improved heat-transfer to the base layer, the aluminum metal 
material of the base layer being substantially free of iron and 
copper constituents and the electrically insulating hard coating 
of aluminum oxide being substantially free of iron and copper 
inclusions for achieving the selected electrically insulated 
relationship with a very thin dielectric layer to provide improved 
heat-transfer between the electrically conductive circuit layer 
and the base layer. Preferably the electrically insulating hard 
coating layer of aluminum oxide comprises a multiplicity of 
sections of the aluminum oxide hard coating material which are 
individually adherent to the base layer and are separated by an 
electrically insulating adhesive material which is disposed on and 
between the sections of the hard coating layer for cooperating 
with the sections of the hard coating layer in securely bonding 
and mounting the electrically conductive circuit layer in the 
desired electrically insulated relation to the base layer with 
improved heat-transfer to the base layer.

Abstract: A wavelength converting optical device includes an 
optical waveguide (10) which has a waveguide portion 
(11) and a cladding portion (12), at least one of which 
is formed of a nonlinear optical material. A funda­
mental wave, incident on the waveguide portion from an

second harmonic wave is output from an output end face 
(10a) of the waveguide. A reflecting film (14) is 
provided on the emerging end face of the waveguide. The 
reflecting film includes a high reflectivity with 
respect to the fundamental wave of a guide mode and a 
low reflectivity with respect to the optical second 
harmonic wave. A wave front converting element (31) 
is arranged to oppose the reflecting film. The con­
verting element has a diffraction grating (32) for 
converting the second harmonic wave, emerging from the 
output end face of the waveguide, into a plane wave.

Title: Device for monitoring the state of function of an accumulator
IPC: G01R31/36
Filed: 1990-09-21
Abstract: The invention relates to a device for monitoring the operational state of an accumulator (1) which is continuously connected to the power system and to the load (3) via a charging rectifier (2) in standby parallel mode. To make a defined statement on the operational state of the accumulator (1), a measuring device (4) is arranged in parallel with the accumulator (1) which causes a defined drop in the power of the charging rectifier (2) for a predeterminable time at basic load and which records the discharge characteristic (E2) produced during the discharging of the accumulator (1) occurring as a result. The charging rectifier (2) is then operated at a power exceeding the basic load by a defined charging current until the voltage at the beginning of gassing of the accumulator (1) is reached and the resultant charging characteristic (L2) and the subsequent drop to the charge maintenance voltage is recorded. The overall charging characteristic (E2, L2) is compared with the model-related reference characteristic (E1, L1) in the new condition of the accumulator (1) concerned. If there is a defined deviation, a signal is output. <IMAGE>

Title: Multicast communication tree creation and control method and apparatus
Inventor: AUERBACH JOSHUA SETH
IPC: H04L12/18
Filed: 1993-05-19
Abstract: In a multicast network communication system, administration of the communication path making up the multicast tree itself has been separated from control and administration of the network. Creation of a multicast distribution tree and control over the membership thereof, is separately controlled independently from the creation and use of the tree transmission path used to communicate among the members of a multicast set. Transmission distribution trees are set up when a transmission request is received and the properties of the transmission path that is required are known. Transmission paths are created and controlled by all nodes in the communications system, each node having necessary control code and processors for responding to requests from set members to transmit a message to groups of users by creating and activating the necessary tree communication path distribution linkages. A distribution tree is created by the Tree Leader by generating a tree address using a random number generator. A tree address correlator is generated utilizing network and node identifiers unique for the network, and a list of subnodes or users connected for each member of the multicast tree set is generated. Using this information, a tree distribution path is computed to cover all of the subnodes required and a tree set up request message is sent by the Tree Leader along a computed path to each involved subnode. Each subnode returns a message indicating whether the tree address is already in use or is available for use. Successfully negotiated tree addresses are marked at the path link initiation and termination points at each node through the network. <IMAGE>

IPC: B65D51/20
Filed: 1994-10-31
Abstract: A cap for a keg spear has internal teeth (13), which snap-engage over an annular projection on the spear. A tamper-evident ring (40) is provided on the cap skirt (12) and connected to the skirt by radial tags (41) having point attachment to the skirt.

Abstract: A co-processor that performs a variety of communication
functions may be accomplished by providing a control section, a
count control section, a plurality of computation elements, and an
output section. The control section, upon receiving a command,
generates a count value signal and a communication function mode
signal. The count control section takes the count value signal and

perform a communication function. The output of the computation
element is routed to the output section which generates, based on
the communication function mode signal, a resultant.
