  • Patent number: 6078109
    Abstract: A power supply system for an electric/electronic apparatus, such as a notebook computer and an expansion unit, which can be separated into a plurality of subunits or combined into one unit. When a DC power of an external power supply is applied to only an DC inlet A, a FET switch is turned off, so that the DC power at the DC inlet A is applied to both the DC/DC converters A and B. When the DC power of the external power supply is applied to both the DC inlets A and B, the FET switch is turned ON, so that the DC power at the DC inlet A is applied to the DC/DC converters A and the DC power at the DC inlet B is applied to the DC/DC converter B. The user can attach the AC adapter to only the DC inlet A or to both the DC inlets A and B to meet the system configuration, i.e., according to what kind of apparatus(es) is connected into the open slot(s).

  • Patent number: 6016248
    Abstract: An information processing apparatus which comprises a main body in a flat, plane box shape, a flat input section provided on the front surface of the main body, a stand, provided on the rear surface of the main body, having two or more tilting positions relative to the main body where it is preferable that the stand has a retracted position wherein the stand falls down into the rear surface of the main body, a first tilt position where the main body in-clines at a relatively small angle to a desk surface, and a second tilt position where the main body inclines at a relatively large angle to the desk surface. In the first tilting position, the main body is inclined slightly toward the front relative to the desk surface. With the main body thus positioned, it is easy to manipulate a pen held against the input face of the input section. In the second tilt position, the main body is held almost upright relative to the desk surface.

  • Patent number: 6008627
    Abstract: A battery pack and an electric/electronic apparatus capable of reliably preventing an overvoltage from being applied to the battery pack without burning a fuse in the electric/electronic apparatus off. The battery pack comprises a battery cell such as a Lithium ion secondary battery, a charge current preventing FET1, a discharge current preventing FET2, a discharge current detecting resistor R2, and a FET control circuit for controlling the FET1 and the FET2, and is characterized in that the FET control circuit detects the value of the current flowing through the battery cell based upon the voltage across the resistor R2, and turns the discharge current preventing FET2 and the charge current preventing FET1 off when the discharge current I.sub.discharge increases to a value which is equal to or larger than the predetermined voltage I.sub.th.

  • Patent number: 5968143
    Abstract: An information handling system transfers command blocks between a host processing side having a host processing unit and a host memory and a local processing side having a local processing unit and a local memory. The command blocks are transferred from the host processing side to the local processing side by storing the host address of the command block in a local side register set. Upon storing the host address a transfer signal is given to a command block transfer controller to start a command block transfer without the local processor unit intervention.

  • Patent number: 5961352
    Abstract: Personal computer motherboards commonly have connectors located on them for the insertion of plug-in adapter cards. Disclosed is a connector having a first opening in which a PCI adapter card may be inserted and a second opening in which an adapter card of a second type, such as an ISA or EISA card may be inserted. The connector has an insulating moulding common to the first and second openings. By using such a connector, the spacing between slots may be reduced from that required when separate PCI and ISA or EISA connectors are used. This allows either a lower profile for a personal computer or for more connection slots to be incorporated.
