Patent EP-0235974-A3 (EP)
IPC: H04B10/00
Filed: 1987-02-11
Abstract: Optical pulses of nominal frequency f₀ and of predetermined 
repetition rate τ -1 / M can be generated by means of the induced 
modulational instability in single mode optical fiber, provided the 
fiber has anomalous dispersion at f₀. The method involves 
coupling (15, 15′) first (13) and second (14) cw or quasi cw optical 
radiation, of frequencies f₁ and f₂, respectively, into the optical 
fiber (17). The resultant radiation in the fiber has frequency f₀ 
between f₁ and f₂, and is sinusoidally modulated with frequency 
|f₁-f₂|. Propagation of the resultant radiation through the fiber 
results in steepening and narrowing of the amplitude peaks. The 
length of the fiber typically is chosen such that, at the output, the 
pulse width τ p  < τ m /4, preferably < τ m /10.

Title: Thermoforming flexible plastic foam shells
IPC: B29C51/04
Filed: 1987-08-14
Abstract: An improved method and apparatus for rapidly forming plastic foam shells from a flexible foam sheet. The foam sheet (10a) is intermittently passed through a radiaent heating unit and is rapidly heated on both sides to 130-250 DEG F to soften the foam. The heated foam sheet is immediately passed through a forming die unit in which the foam sheet is deformed partly into the die cavity (23) by withdrawal of air from the cavity, and a die plug (25) descends and final forms a shell while rapidly cooling the foam shell to below its plastic deformation temperature. By this forming method and apparatus, ethylene-containing foam shells having a depth 10-25 times the foam sheet initial thickness are rapidly formed at 10-30 cycles/minute.

IPC: B01J8/02
Filed: 1988-05-02
Abstract: To obtain a high gas feed, which is as uniform as possible, in a gas feed device for solids beds, for example those in fixed-bed reactors, it is proposed to use perforated gas inlet hoses 1 which are laid in an inert bed 6.

Title: High resolution digital phase-lock loop circuit
IPC: H03L7/081
Filed: 1988-11-08
Abstract: A high resolution digital phase-lock loop circuit is described, 
which is implemented with an input clock reference frequency which 
is approximately the same as the output frequency of the phase-lock 
loop. The output is derived from delaying the input clock a 
variable number of gate delays ranging from no delay to one period 
of the input clock. A shift register controls the number of gate 
delays and a 360 degree phase detector initializes the shift 
register when the output is delayed by one period of the input clock 
to provide no delay. Gate delay variations due to integrated 
circuit process, voltage and temperature are compensated for to 
provide a relatively constant clock phase correction.

Title: Multiple accessing satellite communication system having standby central station
IPC: H04L1/22
Filed: 1989-02-22
Abstract: In a satellite communication system wherein a 
common channel is used for communication between a 
central station (10) and a plurality of remote stations 
(12) through a satellite transponder (11), in order to 
avoid system down due to fault of transmission of a 
broadcasting signal with a timing signal by the central 
station (10), the central station (10) comprises two 
portions (13, 14) positioned at different locations and 
a controller (15). When the first portion (13) detects 
fault of transmission of the broadcasting signal during 
the first portion (13) operates to communicate with the 
remote stations (12) under transmission of the 
broadcasting signal, the controller (15) is notified the 
fault and starts the second portion (14) in place of the 
first portion (13) so that the communication is 
maintained in the system without false. Those portions 
(13, 14) are assigned with ID numbers and can detect the 
fault by detecting operation of ID number. Each of 
remote stations (12) has timing offset data sets 
corresponding to the first and second portions (13, 14), 
selects one of the data sets by detection of the ID 
number in the broadcasting signal received, and 
determines a slot timing for transmitting a packet 
signal.

Title: Optical information recording method and apparatus and recording medium used therefor
IPC: G11B7/126
Filed: 1989-06-07
Abstract: A method and apparatus for optically recording 
information in which the phase state of each recording 
position of the recording film of a recording medium such 
as an optical disk is reversibly changed between an 
amorphous phase and a crystalline phase using a single 
laser beam, thereby optically recording information on the 
recording film. The recording position on the recording 
film is heated to the melting point thereof or more 
through laser beam irradiation irrespectively of the 
information to be recorded. After completion of the 
heating, in order to change the phase state of the 
recording film at the recording position in accordance 
with the information, the power and/or irradiation time of 
the laser beam is controlled so as to provide different 
times required for the temperature of the recording 
position to pass the crystallization temperature region of 
the recording film. The recording medium has at least one 
record of data indicative of the melting point of the 
recording film and data indicative of the time required to 
pass the crystallization temperature region for placing 
the recording position in the amorphous or crystalline 
state.

ated from a cathode gun assembly (11) and a DC magnetic 
field is applied to the electron beam (e) from solenoid

Title: Logic simulation method and apparatus
IPC: G06F19/00
Filed: 1989-03-06
Abstract: Determining the operation of a logic circuit 
through calculation is generally called logic simulation. 
Especially, in event driven type logic simulation, signal 
status changes at input and output terminals of an element 
of the logic circuit are deemed as events and only for an 
element in which an event occurs at its input terminal, 
the signal status at its output terminal is calculated. 
In the event driven type logic simulation, a series of 
signal status changes externally applied to the logic 
circuit is stored, as injection events, in a memory of a 
logic simulation apparatus. If injection events are all 
stored in the memory before execution of the simulation or 
injection events are stored in the memory by temporarily 
stopping the simulation after start thereof, most of 
memory capacity is consumed by the injection events or 
simulation speed is degraded. To solve this problem, an 
identifier (called color) is added to an event and when an 
injection event is injected, the injected event is 
associated with auxiliary time representing a minimum of 
values of event times of injection events expected to be 
injected after injection of that injected event. Color 
and auxiliary time are used to permit execution of the 
simulation in parallel with injection of injection events.

lines (72) remain low if an existing circuit board 
address is presented or a memory operation is 
occurring. All the AEN lines go high during a DMA 
operation.
