Patent CA-2041450-A1 (CA)
Inventor: KIMURA HITOSHI
IPC: H02G15/00
Filed: 1991-04-29
Abstract: ABSTRACT OF THE DISCLOSURE    There is provided a rubber/plastic insulated power cable or a joint of power cables which comprises a conductor or a conductor joint having an inner semiconductor layer and an insulation layer, and if necessary, an outer semiconductor layer, formed thereon in the order named, at least one of these layers being formed of a crosslinked structure of an olefin resin composition containing an olefin resin, an organic peroxide, and 2,4-diphenyl-4-methyl-1-pentene.  The .theta. serves to inhibit "amber" of the olefin resin composition by the organic peroxide used and to increase the degree of crosslinking of crosslinked structure.  Also, the olefin resin with a high melting point can be used as a base resin.  Therefore, the resultant power cable and joint have highly improved AC breakdown strength, impulse breakdown strength at a high temperature and much less generation of electrical trees due to "amber", so that they are useful particularly high-voltage application.

Title: Bios load for a personal computer system having a removable processor card
Inventor: BEALKOWSKI RICHARD
IPC: G06F13/00
Filed: 1992-03-24
Abstract: BIOS LOAD FOR A PERSONAL COMPUTER SYSTEM HAVING A REMOVABLE PROCESSOR CARD                          ABSTRACT      An apparatus and method for loading BIOS stored on a direct  access  storage  device  into  a  personal  computer system.  The personal computer system comprises a processor card including a system processor and a read only memory; a planar board including a random access memory; and at least one direct access storage device.  The processor card is removably mounted on the planar board.  The read only memory includes a first portion of BIOS and data representing the type   of   system   processor   and   system   planar   I/O configuration.   The first portion of BIOS initializes the system and the direct access storage device to read in a master boot record into the system from the direct access storage device.   The master boot record includes a data segment and an executable code segment.   The data segment includes  data  representing  system hardware  and  a  system configuration which is supported by the master boot record. The first BIOS portion confirms the master boot record is compatible with the system hardware by verifying that the data from the data segment of the master boot record agrees with the system processor,  system planar,  and planar I/O configuration.  If the master boot record is compatible with the  system hardware,  the  first BIOS portion vectors the system processor to execute the executable code segment of the  master  boot  record.   The  executable  code  segment confirms that the system configuration has not changed and loads in the remaining BIOS portion from the direct access storage device into random access memory.   The executable code segment then verifies the authenticity of the remaining BIOS  portion  and vectors  the  system processor  to begin executing  the  BIOS  now  in  random  access  memory.   BIOS executing  in  random  access  memory  then  boots  up  the operating system to begin operation of the personal computer system.

Abstract: An apparatus for contactless data and energy transmission and includes a stationary part having device for transmitting and receiving data and device for generating energy. A movable part has a plurality of rectifier devices each with at least one output and modulators each being connected downstream of a respective one of the rectifier devices. A first pair of coils is connected to the device for transmitting and receiving data and to the rectifier device for transmitting data from the stationary part to the movable part. A second pair of coils is connected to the device for generating energy and to the rectifier device for transmitting energy from the stationary part to the movable part. The coils in the stationary part are arbitrarily associated with the coils in the movable part, and data is transmitted from the movable part to the stationary part by a load variation at the coil of the movable part not being used for energy transmission. Controllable semiconductor elements each having a load path are connected between the at least one output of a respective one of the rectifier devices and a charge capacitor at which an unregulated operating voltage can be picked up, for delivering output signals of the rectifier device to the charge capacitor. A method for operating the apparatus includes ascertaining which coil is used for energy transmission during an initializing time within the movable part, and thereupon disconnecting the rectifier device and the modulator from the charge capacitor through the applicable controllable semiconductor element.

Filed: 1992-05-01
Abstract: Compensation for process direction photoreceptor motion in a Raster Output Scan system is provided by moving the cylinder lens located between the laser source and a rotating spot scanning mechanism, e.g., a polygon. The cylinder lens is moved in the process direction in response to error signals generated by a SOS detector and timing marks on the photoreceptor drum surface, or an encoder on the drum shaft. The lens movement is obtained by sending motion error signals to a piezo-electric actuator which increases in length to impart the desired motion to the cylinder lens.

Filed: 1992-07-29
Abstract: HORIZONTALLY ORIENTED ROTARY MACHINE HAVING       INTERNAL LUBRICATION OIL PUMP            ABSTRACT OF THE DISCLOSURE         A rotary machine, such as a horizontally oriented scroll type refrigerant compressor is disclosed. The compressor includes a compressor housing, an inner block fixedly disposed within the compressor housing, a drive shaft extending substantially in the horizontal direction, and a driven mechanism, such as a compression mechanism operatively connected to one end of the drive shaft. The drive shaft is rotatably supported by the inner block and the compressor housing. A shielding element, such as an annular cylindrical member is fixedly held between the inner block and the compressor housing to prevent the drive shaft from passing through an oil sump of the housing. An internal lubrication oil pump is formed by the elements which are associated with the drive shaft, and is operated by virtue of the rotational motion of the drive shaft in order to supply the lubrication oil from the oil sump to the frictional surfaces of the internal component parts of the compressor. According to the construction and operational manner of the oil pump, the oil pump can be used for various types of horizontally oriented rotary machines. The drive shaft can also rotate without receiving oil viscous drag.
