Patent CA-2032854-C (CA)
Title: Table editor
Inventor: SIIO ITIRO
IPC: G06F17/24
Filed: 1990-12-20
Granted: 1994-02-08
Abstract: ABSTRACT          Disclosed is a table editor including a display device and   line   information   storage   means   for   storing information  indicative  of  lines  making  up  a  table. Further  information  storage  means  store  information indicative of pointing marks.   The table and pointing marks are displayed on the display and location pointing means  updates  pointing mark  information  to  direct  a location of a pointing mark. Upon the generation of a line  identifying  command,  line  identification  means identifies a line indicated by a pointing mark based on the  pointing  mark  information  and  the  identifying command.  Insertion commands update the line information so that if a line identified by said line identification means is located between two consecutive rows,  one or more new rows are inserted and, if a line identified by the  line  identification means  is  located between two consecutive columns, one or more new columns are inserted in response to the insertion command.

Title: Group control for lifts with immediate allocation of target calls in dependence on the call entry location on a storey
Inventor: SCHRODER JORIS
IPC: B66B1/20
Filed: 1991-01-18
Granted: 2003-03-25
Abstract: Summary By this group control, the cages of a lift group can be so selected for boarding passengers that the boarding passengers arrive at the shaft door of the selected lift earlier than the selected cage, whereby unnecessarily long stops are avoided. For this purpose, a store (15) in which the times needed by a passenger on a storey for the paths between the respectively actuated call-registering and indicating equipment and the shaft doors of the lift are stored, is provided for each lift. A comparator (16) connected with the store (15) compares the time associated with the actuated call-registering and indicating equipment with the travelling time of the cage to the call input storey. If the travelling time is less than the time needed by the passenger to get to the shaft door concerned, a switching equipment (17) connected to the output of the comparator (16) becomes effective in such a manner that the lift concerned is excluded from the call allocation procedure.

Title: Emergency braking system for a squirrel-cage elevator motor
Inventor: HAKALA HARRI
IPC: H02P3/24
Filed: 1991-03-05
Granted: 1994-01-18
Abstract: ABSTRACT            A procedure and apparatus are provided for braking a squirrel-cage elevator motor fed by a frequency convertor in fault situations using a direct current supplied from a d.c. voltage source.  In the procedure of the invention, the current in at least one of the motor phases and the rotational speed of the motor are measured. When the elevator speed exceeds the value corresponding the nominal slip and the motor current is less than the nominal magnetizing current, a switching device is caused to connect a direct current from a d.c. voltage source to the motor, thereby providing a magnetizing current and allowing the motor to act as an eddy current brake.

Title: Magnetic disk device
Inventor: NAKAYAMA JUNICHIRO
IPC: G11B21/12
Filed: 1991-08-28
Granted: 1996-03-05
Abstract: A  magnetic  disk  device  having  a  floating-type magnetic head, for use with a disk-shaped recording medium having a sliding area for the floating-type magnetic head formed outside a recording area.  The length in the disk radial   direction   of   a   suspension   supporting  -the floating-type  magnetic  head  is  varied  depending  on individual magnetic disk devices.  In another arrangement, a control means is  provided for  setting two reference values  so that a radial position of the  floating-type magnetic head detected by a detection section is compared with these reference values, and for alternating one of the preset reference values to the other reference value upon receiving a rotation stop signal.  In still another arrangement, control means is provided, whereby a radial position for sliding of the floating-type magnetic head is randomly varied within the sliding area.   According to these arrangements, since the radial position for sliding of the floating-type magnetic head is varied within the sliding area without being located at the same position, abrasion within the sliding area can be dispersed.  As a result, it becomes possible to extend the longevities of the floating-type magnetic head and the recording medium.

Title: Electronic control module
Inventor: KESKULA DONALD HENRY
IPC: F02P5/15
Filed: 1992-01-03
Granted: 1998-12-01
Abstract: An electronic control module for use in controlling a vehicle comprises a first processor 10 adapted to calculate the fuelling requirements of the engine and spark advance, and also to control a plurality of diagnostic tests for testing engine operating paramenters.  A second processor 12 triggers the spark and spark dwell timing together with the start of fuel injection.  By such partitioning of tasks it is possible to provide a wide variety of facilities with a low cost electronic control module.         The second processor 12 is adapted to operate the engine in a back-up mode on failure of the first processor 10 by use of look-up tables fox fuel pulse width and spark advance.  The vehicle therefore remains operational even on failure of part of the electronic control module.

Title: Method and device for measuring the concentration of particles present in a gas
Inventor: RUEEGG WALTER
IPC: G01N27/66
Filed: 1992-03-02
Granted: 2000-05-16
Abstract: In a method and a device for measuring the concentration of particles present in a gas, in which a gas stream is guided past a UV light source, the particles are ionized and filtered out and the resulting ionic current is measured, the gas flow required is produced by thermal convection using an internal or external heat source. A suitable internal heat source in this context is, for example, the UV lamp (2) itself, which heats the gas via a radiation absorber (5).      The elimination of a mechanical pump reduces the space requirement, power consumption and susceptibility to faults of the measuring arrangement.

Granted: 1998-09-29
Abstract: The reproduction characteristics, particularly the C/N ratio of a reproduced signal of an optical recording medium are deteriorated by an unevenness or deformation of an optical recording layer due to a convex or concave configuration of an underlying guide means is formed on the surface of the substrate. This deterioration can be prevented by disposing a planalization layer under the recording layer but the planalization layer lowers the efficiency of the servo tracking.  This lowering of servo tracking efficiency is prevented by insertion of a dielectric layer between the planalization layer and the guides.
