Patent EP-0351824-A3 (EP)
IPC: F16H61/02
Filed: 1989-07-19
Abstract: A line pressure control during a shifting 
operation of an automatic transmission is disclosed. 
Quality of each shifting operation is represented by 
a predetermined variable, viz,, an inertia phase time 
during which a gear ratio undergoes a variation. 
When a deviation between circumstances detected upon 
occurrence of a shifting operation and predetermined 
circumstances under which a target value is set fails 
to fall in a predetermined range, a deviation 
indicative signal is generated. Upon absence of this 
deviation indicative signal after completion of the 
shifting operation, the inertia phase time measured 
during the shifting operation is compared with the 
target value and the line pressure is adjusted in 
response to this comparison result when the shifting 
operation of the same kind is to occur under 
substantially the same circumstances detected. In 
other words, the learning to adjust the line pressure 
is prohibited when the deviation indicative signal is 
present.

image signatures (100) to identify a particular one of the 
predetermined audience members. These steps are repeated 
to identify all of the located individual audience members

IPC: G06F17/30
Filed: 1989-06-29
Abstract: A real-time database provides the predictable, high speed 
data access required for on-line applications, while providing 
flexible searching capabilities. The data retrieval routines include 
the option to "read-through-lock" to access data in locked data 
tables, the capability to directly access to data using tuple 
identifiers, and the capability to directly access unformatted data 
from input areas which contain blocks of unformatted data. The data 
updating routines include an option to omit index updating when 
updating data and an option to update data in a locked data table. 
Multiple indexes can be defined for a data table. Thus, high speed 
searches can be performed based on a variety of data fields. The data 
storage and retrieval mechanisms are independent and there are hash 
index tables that connect the multiple index keys to the data tables. 
The data table structure includes a column defined for storing tuple 
identifier strings. These tuple identifiers can be used as pointers 
for chaining to related data stored in other data tables. The database 
has relatively small programmatic memory. There is a common structure 
for user data tables, index tables and system tables. The database 
includes a minimum number of routines with certain routines providing 
multiple functionality.

Title: Multilayer structure having a layer comprised of a blend of polyphenylene ether and high impact polystyrene
IPC: C08L51/04
Filed: 1990-05-23
Abstract: A multilayer packaging structure for microwave 
food reheating applications or for sterilized hot 
filling is provided having an outer layer prepared 
from a blend of polyphenylene ether and a high 
impact polystyrene. The polyphenylene ether-high 
impact polystyrene layer is useful as a structural 
support layer and provides resistance to distortion

hot filling. The PPE/HIPS blend layer serves to 
increase the high temperature performance of the 
coextruded structure without sacrificing the 
thermoformability characteristics generally 
associated with HIPS based monolayer or multilayer 
structures. The ethylene vinyl alcohol or 
polyvinylidene chloride layers act as the oxygen 
barrier to prevent food spoilage and the polyolefin 
layer acts as a moisture barrier.

Patent EP-0381519-A3 (EP)
Title: Stepper motor torque variance compensation using varied applied voltage
IPC: G11B21/08
Filed: 1990-02-02
Abstract: The present invention utilizes the output of a 
voltage regulator to control the drive voltage to the 
stepper motor (14) driven transducer positioning 
system (15, 16, 19a, 19b, 22, 23, 21, 29 20). This 
technique will significantly reduce the access time. 
More specifically, in this invention, the output of a 
digital-to-analog converter (DAC) (50) is used to 
control the output voltage level of a voltage 
regulator circuit (Figure 4) which supplies the 
voltage of the stepper motor drive transistors (Q3 
58; Q2 63; Q1 54). In order to optimize the drive 
voltage output from the voltage regulator to the 
stepper motor (14) for each disc drive, a series of 
seeks is performed using identical starting and 
target tracks. As each seek is performed, the input 
to the DAC is incremented by a microprocessor (11) 
causing the stepper motor drive voltage to be 
increased in one milli-volt increments. A ring 
detector (32) (which provides an output count of the 
number of target track crossings by the transducer 
(10) before the transducer settles on the target 
track) monitors the settling time of the head over 
the center of the target track. The data identifying 
the voltage regulator output which results in minimum 
ring-out count is stored and used from then on for 
that stepper motor disc drive system as the optimum 
access tuned voltage. This data will be applied by 
the microprocessor to a DAC, and output from the 
voltage regulator to the stepper motor drivers during 
each stepping sequence.  
     Typically, this tuning process is originally 
accomplished when the disc drive is first powered on 
and is part of the normal power-on recalibration 
routine. The disc drive could also be returned on 
 
 
command or by any other interrupt routine parameter 
such as time or temperature change.  
     Alternatively, the calculated optimum drive 
voltage could be stored on a non-user accessible 
track of the disc surface of the disc drive, and 
automatically accessed as part of the power-on 
rountine for the disc drive.
