Abstract: A PLL circuit includes a reference signal genera­
tor (10A), a phase detector (14), a voltage controlled 
oscillator (VCO) (11), a mixer (12), and a local oscil­
lator (20). The VCO (11) generates a signal having a 
desired frequency within a predetermined frequency band­
width. A switch (17) is connected between an output 
terminal of the phase detector (14), an output terminal 
of the mixer (12), and an input terminal of the VCO 
(11). The switch (17) performs a switching operation 
to connect the output terminal of the phase detector 
(14) to the input terminal of the VCO (11) in a first 
state, and, in a second state, to connect the output 
terminal of the mixer (12) to the input terminal of the 
VCO (11). A controller (19) is connected to the switch 
(17) so as to selectively supply first and second 
switching signals to the switch (17) and establish con­
nection relationships corresponding to the first and 
second states. The controller (19) substantially deter­
mines a coincidence state between a frequency of an out­
put signal from the VCO (11) and a frequency of a local 
oscillation signal from the local oscillator (20), so as 
to generate the first switching signal for establishing 
the connection relationship corresponding to the first 
state, when a determination result representing a prede­
termined coincidence is not obtained, and to generate 
the second switching signal for establishing the connec­
tion relationship corresponding to the second state, 
when the determination result representing the predeter­
mined coincidence is obtained.

Title: Reflection holograms and the replication thereof
IPC: G02B5/32
Filed: 1988-08-18
Abstract: Reflection holograms are described and are prepared from a 
transmission hologram. The reflection hologram is divided 
into a plurality of sequential parallel notional strips 
(3,4,5,6), each of which is divided into bands (71), the 
bands and strips extending across the hologram from one 
side or end to the other and being parallel. Each band of 
a strip contains information derived from a respective 
notional strip into which the transmission hologram was 
divided during production of the reflection hologram. 
Thus each strip of the reflection hologram contains 
information derived from the whole of the transmission 
hologram. The reflection hologram is produced from the 
transmission hologram by a process in which each band of a 
notional strip of the reflection hologram is exposed in 
turn to a respective notional strip of the transmission 
hologram.  
     The reflection hologram may be copied by placing it in 
contact with photosensitive holographic material and 
exposing the latter by notional strips with reference to 
respective notional strips in the reflection hologram. 
The exposure may be by way of exposing each strip in turn 
using a continuous laser beam or by way of exposing 
several strips at once using a pulsed laser beam and a 
holographic optical element.

Title: A process for forming a schottky barrier gate on gallium-arsenide
IPC: H01L21/3205
Filed: 1989-09-29
Abstract: Provided is a process for precisely forming a Schottky 
barrier gate on GaAs. In the process, a layer of 
polyimide is spun onto a doped GaAs substrate having a 
passivating layer thereon. A resist layer is then 
spun onto the polyimide, and either deep ultraviolet 
lithography in conjunction with a clear field mask, or 
direct electron beam exposure, is used to define a 
gate region. After exposure, the resist is developed, 
leaving the unexposed portion of the resist in place 
on the polyimide layer. A metal transfer layer is 
then deposited over the structure, and the remaining 
resist is dissolved leaving a hole in the metal 
transfer layer. The polyimide and the passivating 
layer are etched down to the surface of the substrate 
through the passivating layer. The substrate is then 
dry etched, and then wet chemical etched to form a 
recess for the Schottky gate. The Schottky gate metal 
is deposited onto the surface of the structure and 
through the hole onto the substrate. The polyimide is 
dissolved and the upper layers lifted off leaving the 
Schottky metal gate deposited in the exposed recess in 
the GaAs substrate.

Patent EP-0369690-A3 (EP)
IPC: H04B10/27
Filed: 1989-11-10
Abstract: In an optical switching network, a master optical space switch (100) 
is interconnected with remote slave equipments (110,120) for switching 
block-multiplexed messages among the remote equipments. The master 
optical space switch responds to a frequency reference clock (31) and 
steps through a sequence of states, or configurations, for establishing 
various routes among the remote equipments for appropriately routing the 
messages to correct destinations. The frequency reference clock also 
is distributed to the remote equipments. During one of the states per 
frame, each remote slave equipment transmits a distinct signature signal. 
All of the slave equipments are connected through the master optical 
space switch to return to themselves their own signals transmitted 
during that time slot. Each remote slave equipment compares the returned 
signal with the originally transmitted signature signal to determine 
how much the round trip delay has varied from a nominal value. 
Phase of a local control clock (125,155) signal in the 
slave equipment is adjusted to counteract the variation of the round trip 
delay. Thus the operation of the slave equipment is adjusted into 
synchronization with the master optical space switch so that messages 
transmitted from the slave equipment arrive at the master optical space 
switch at the appropriate time with respect to the periodic 
reconfigurations 
of the master optical space switch.

Title: Quadruple word, multiplexed, paged mode and cache memory
IPC: G06F12/0886
Filed: 1990-05-11
Abstract: A 64 bit wide memory is multiplexed over a 32 bit data 
bus to provide data to a 64 bit line size cache memory controlled by 
an 82385 cache controller. The memory addresses to all 64 bits of 
memory are held during the entire transfer so that a zero wait state 
second 32 bit transfer occurs. Logic develops the necessary next 
address and ready pulses and blocks these signals from the cache 
controller. Logic also handles the bit 2 address for the main and 
cache memories. The main memory is operated in paged mode to further 
increase system performance.
