Patent EP-0177141-A3 (EP)
IPC: H01S5/00
Filed: 1985-08-09
Abstract: In order to narrow the far field of the light output from a 
multilayer semiconductor laser structure in a direction 
perpendicular to the layers, whilst maintaining a high 
confinement factor, a thin layer (6,7) is interposed between 
the active layer (1) and a conventional light confining layer 
(4, 5). The thin layer is of a lower refractive index than the 
light confining layer, which in turn is of a lower refractive 
index than the active layer.
Patent EP-0189168-A3 (EP)
IPC: B41J33/52
Filed: 1986-01-21
Abstract: A ribbon cassette of the kind used to store a reel of typing 
ribbon, comprises a casing (6), a primary spool (8) mounted an 
a hub (16) and upon which unused ribbon is wound, and a 
secondary spool (10) in the casing upon which used ribbon is 
wound. The secondary spool (10) is provided with means (12) 
to be engaged by a drive member of (e.g.) a word processor or 
computer printer, to cause the secondary spool to rotate, and 
to draw ribbon from the primary spool onto the secondary 
spool.  
     The cassette comprises means to resist reverse winding of 
the primary spool, said means comprising a first toothed ele­
ment (20) forming part of a fixedly mounted on the primary 
spool, and a secondary toothed element (21) mounted in a 
diametral slot (24), and which is urged into engagement with 
the first toothed element (20) by spring means (28). Engage­
ment between the two toothed elements permits normal win­
ding of tape onto the secondary spool from the primary spool, 
but resists reverse winding of the primary spool.  
     The spring element (28) engages the ribbon, to maintain 
tension in the ribbon during use.  
     Additionally, the ribbon cassette comprises an insert 
member (80) comprising an operative portion which may be in­
serted through a slot (78) in the base (6) into a position in which 
it engages the primary spool to prevent rotation thereof during 
transportation, the insert member comprising a supplementary 
portion located on the exterior of the casing which may be 
manually grasped to enable the insert member to be removed 
from the casing of the ribbon cassette in preparation for use 
thereof.

pertaining to the performance of the equipment. The 
availability means (132), on the other hand, is operative as a 
source of data pertaining to the availability of the 
equipment. Continuing, the degradation means (134) is cross-­
linked to both the performance means (130) and the availability 
means (132), and is operative as a source of data pertaining to 
the degradation of the equipment. Lastly, the updating means 
(136) is operative as a source of data relating to the latest 
reported status of the equipment.

Title: Apparatus for compensating movement in a picture derived from a television signal
IPC: H04N5/14
Filed: 1986-07-28
Abstract: image movement correction is provided for example in a field conversion television system by deriving simultaneously two fields of a selected number of lines from an original single field and vertically shifting one of the derived fields by 0.5 lines. A movement vector is determined (5) for each field and movement correction is performed based on a current field and a preceding field, in the case of a moving object in the image. If no moving object is present, linear approximation is employed to correct for motion caused by the field number conversion. Two memory systems (51 to 54 and 55 to 58) are provided for the two simultaneous fields and also selectively to obtain specific horizontal lines of the current and preceding fields, relative to both simultaneously derived fields. Ultimate selection of a field for display is based upon the detected movement vector.

IPC: B23Q5/38
Filed: 1983-08-26
Abstract: A surface grinding machine (10) capable of being 
computer operated and having a multi-function capability 
for performing conventional slot and surface, plunge, 
side wheel, creep feed and short stroke grinding in any 
desired combination or sequence. A table (18) containing 
a workpiece (90) may be driven by a highly tensioned, 
circulating primary belt drive system (50) capable of 
providing a desired grind with a desired length and 
speed upon command. The base (12) is preferably formed 
as a unitary body, and the table (18) travels on ways 
(20) which are formed integrally with the base (12). 
The column (14) containing the grinding wheel (40) moves 
with respect to the workpiece (90) along cross ways (16) 
transverse to the table ways (20) which are supported 
along their length by the base (12). The column drive 
(100) is coupled to the column (14) by a mechanically 
and thermally isolated ball screw nut mount (118, 120, 
122 and 124) which eliminates screw nut shoulder weave 
and reduces thermal conduction into the column (14). A 
 
 
housing (22) containing the grinding wheel (40) assembly 
moves vertically along ways (24) in the column (14) and 
a magnetic brake (156) is utilised in the vertical drive 
(154) for the wheel housing (22) to prevent damage to 
the workpiece (90) during power interruption. Both the 
vertical ways (24) for the wheel housing (22) and the 
horizontal cross ways (16) for the column (14) are 
self-aligning. A computer terminal (26 and 
258) may be provided for automatic control of the 
machine, and a manual control panel (28) may also be 
provided, which is slidable across the front of the 
machine (10) for convenience of oepration thereof.

Title: Prepaid charge counting apparatus
IPC: G07C1/30
Filed: 1989-02-24
Abstract: A prepaid charge counting apparatus (10) to be employed, for example, in a 
particular parking system in which the parking period of time is limited. In such a case, the driver has to purchase the 
apparatus in advance such that a count corresponding to the prepaid amount is assigned to the apparatus.  
     When parking a 
car in the parking place, the user first operates the ON/OFF operation unit (12) to initiate the respective sections of the 
apparatus (10), and then the remaining amount of the count and the consumption state of the time are appropriately displayed 
on the display (11).  
     This apparatus (10) is placed at a position in a car visible from the outside thereof such that the 
time measuring unit (41) continuously measures the consumed period of time and that the arithmetic unit (42) converts the 
measurement result of the time measuring section (41) into a count so as to compute the remaining amount of the count. The 
control unit (43) updates the display contents on the display section (11) based on the measurement result of the time 
measuring section (41) and the computation result of the arithmetic unit (42).  
     The manager of the parking place monitors 
the display contents to appropriately check the consumption state of the time. In consequence, in order to construct a 
prepayment system in the parking place, when the apparatus is employed, the inventment for the special    facility 
and the management cost can be unnecessitated. Furthermore, the user is relieved from the annoying operation of the prepayment 
of the parking charge for each parking operation.
