Patent EP-0189976-A3 (EP)
Title: Extremely lightweight, flexible semiconductor device arrays and method of making same
IPC: H01L31/042
Filed: 1986-01-09
Abstract: An extremely lightweight, interconnected array of semi­
conductor devices, such as solar cells, is formed from a large 
continuous area of semiconductor material (3, 23, 43, 83, 
123) disposed on an unconventonally thin, electrically con­
ducting stubstrate (1, 21, 41, 81, 121). The interconnections 
are formed by removing portions of the substrate to form 
substrate islands (13, 35, 55, 95, 141, 163, 183) underlying a 
layer of semiconductor material which underlies a transpa­
rent conductive oxide (5, 25, 45, 83, 125, 179). The oxide layer 
may likewise be formed into mutually isolated islands (7, 29, 
47, 89, 131, 181) that overlay the areas between the substrate 
islands. Individual units or cells so formed may be intercon­
nected by depositing a conducting material on, alongside 
and at least partially between islands of oxide and/or 
semiconductor, by depositing a metal grid (27) on the oxide 
layer and burning conducting paths (31) to the substrate 
islands, or by piercing the layers and disposing a conducting 
material in the holes (133) pierced.  
     The unconventionally thin substrate may be a sheet of 
electroformel nickel or other thin metal or may be an initially 
thick substrate that is thinned by chemical etching after other 
array processing steps are completed. To maximize the 
output power-to-weight ratio of a solar cell array, the 
conventional substrate (159, 171) may be removed entirely. 
In that process, a dissimilar layer (161, 173), such as a back 
reflector, is deposited on a support, such as a conventional 
substrate, before the semiconductor material (23, 177) is 
deposited. After all other processing, the support (159, 171) 
is removed by chemical etching to produce a substrateless 
array of devices. Typically, the array is encapsulated by a 
protective glass or polymer film. An encapsulant (33) is 
preferably applied to the exposed surface of the semiconduc­
tor material to protect it while the substrate is being thinned 
or removed. Subsequently, an encapsulant (37) is applied to 
the rear of substrate side of the array. An insulating layer 
(173) may be interposed between the support (171) and 
semiconductor layer (177) and act to encapsulate the rear of 
a substrateless array when the support is etched away to 
produce an ultimate power-to-weight ratio array.

IPC: E05C17/50
Filed: 1986-04-08
Abstract: The present invention relates to a mechanism for 
restricting the extent to which a closure member for an 
access aperture into a structure can be moved from a fully 
closed position to an open position via a pre-determined 
partially open position at which further opening of the 
closure member can be impeded by the said mechanism, the 
mechanism being adapted to be mounted internally of the 
structure and adjacent the head and/or foot of said aperture, 
said mechanism comprising:  
a stop member adapted to be mounted on or to engage 
with the head and/or foot of the closure member and;  
a guide member adapted to co-operate with the said 
stop member which guide member is adapted to guide the 
travel of the stop member between an operative position at 
which the mechanism acts to impede further opening of the 
closure member beyond the said pre-determined partially 
open position and an inoperative position in which the 
mechanism does not impede the opening or closing of the 
closure member, said travel passing through an intermediate 
position at which the closure member must be substantially 
in the fully closed position to permit the passage of the stop 
member to enable it to travel from its operative position to its 
inoperative position; the said guide member being adapted 
to be mounted adjacent said aperture so that at least that 
part thereof co-operating with the said stop member is 
located below the lower or above the upper extremity of said 
closure member.

Title: Refrigerated counter unit
IPC: F25D17/06
Filed: 1987-02-24
Abstract: The refrigerated counter unit is a further development of German Offenlegungsschrift 3,230,792. It is essentially characterised in that the fan is arranged in the passage opening of the bottom of the counter bed and no longer in a housing below the counter bed and it conveys the flow of intake air into a distribution chamber situated above said counter bed, from which at least one intake air channel branches off, in that the flow of return air is guided in the housing essentially vertically from the top to the bottom through the refrigeration source and the flow of intake air passing through the refrigeration source - after deflection - is guided essentially vertically from the bottom to the top to the fan in the bottom of the counter bed. A more effective refrigeration can be achieved in this manner with reduced production expenditure. <IMAGE>

Patent EP-0257625-A3 (EP)
Title: Lock circuit for carrier recovery from a qam signal
IPC: H04L27/38
Filed: 1987-08-25
Abstract: The circuit is provided for the demodulation circuit of a digital radio system, consisting of a demodulator (D), a voltage-controlled oscillator (VCO) and a carrier signal control voltage generator (TR) with a level monitor (P) at its input and an error monitor (F) for the bit error rate at its output. It is designed to synchronise carrier recovery within the shortest possible time following signal interruption, e.g. due to fading. A memory circuit (SP) is disposed between the carrier signal control voltage generator (TR) and the voltage-controlled oscillator (VCO), which ensures that, when the signal returns, the VCO continues to oscillate at the frequency prevailing before the interruption. In the event of an expected interruption in signal transmission, indicated by a rise in the bit error rate above a defined threshold, the error monitor (F) initiates the disconnection of the memory circuit (SP) from the VCO input before the interruption occurs. A sweep generator (W) with a preceding delay circuit (V) connected between the error monitor (F) and the carrier signal control voltage generator (TR) ensures the locking function in any event e.g. in the event of frequency offset following a long interruption. <IMAGE>
