Patent CA-2001298-C (CA)
Inventor: NAKASHIMA YASUHIKO
IPC: G06F13/10
Filed: 1989-10-24
Granted: 1996-08-27
Abstract: A virtual computer system has a plurality of virtual computers and a virtual computer monitor for monitoring the virtual computers and for providing translation information describing the relationship between a virtual identification of the input/output apparatus structure to be recognized by the virtual computers and a physical identification to be actually  used  by  the  input/output  apparatus structure.    A hardware dynamically creates a subchannel necessary for performing an input/output process of the virtual computers and translation information when the virtual computer monitor provides the translation information to the hardware.    The  hardware  translates  the  virtual identification to the physical identification based on the translation information when the virtual computer issues the input/output instruction, and for identifying the subchannel, thereby performing the input/output process.  The hardware also translates the physical identification of the control block to a virtual identification to be used by the virtual computer when an input/output interruption is generated, by using the subchannel by the input/output apparatus, thereby providing an input/output interruption to the virtual computer.

Title: Calibrating lasers for optical recording using a maximal readback signal amplitude as a criterion
Inventor: FINKELSTEIN BLAIR IAN
IPC: G11B7/125
Filed: 1991-02-25
Granted: 1996-03-05
Abstract: A magnetooptic recorder uses a magnetooptic disk for any predetermined number of radially inward tracks which are designated as calibration tracks.  One of the calibration tracks  is selected as  a  laser calibration track.  The selected track is high powered erased and a test pattern is written on the track.  A test pattern is repeated at diverse levels of laser recording power.  A test pattern preferably  includes  or  is  limited  to  the  highest frequency to be recorded in the ensuing data recordings. The recorded test pattern is read back with the readback signal amplitude being envelope indicated and detected. A table of signal envelope values is created in a digital computer. The values then are fit to a curve using second order polynomial curve fitting techniques.  The maximal readback signal amplitude is then selected from the curve corresponding to laser write power used to obtain that maximum  signal  amplitude  and  is  then  selected  as  a criteria for indicating the laser write power as well as the erase write power.

Title: Packets and packaging
Inventor: VERNON GEOFFREY WILLIAM
IPC: B65D85/808
Filed: 1991-03-20
Granted: 2001-09-04
Abstract: Twin compartment packets, eg. tea bags, are formed with the compartments connected at the heads of the packet and optionally at the tails. The packets are produced from a pair of compartmented tubular webs that are brought together with the compartments in register, the webs then being interconnected at the compartment end seals and severed at those seals to form the separate packets. Apparatus for performing the process deposits doses of tea at spaced intervals onto the two separate webs before forming them into the tubular compartmented webs, brings the compartments of the two webs into register, interconnects the registered compartments, and separates the interconnected compartments into individual packets while the web advances continuously through the apparatus. The process is capable of high production rates because the webs are able to move through the successive stages at a uniform speed.
