IPC: G11C16/16
Filed: 1995-09-29
Abstract: In a method of initializing an electrically erasable non-volatile semiconductor memory device including a memory cell array composed of a plurality of blocks (1), an erasing operation to each of the memory cell blocks is first executed until a threshold voltage of each memory cell (M nm ) of the each memory block is equal to or lower than a first predetermined value which is lower than a second predetermined value as a final upper limit of a final distribution of threshold voltages of all the memory cells in the each memory block. Next, a programming back operation is executed to the each memory block until each memory cell has the threshold voltage equal to or higher than a third predetermined value as a final lower limit. Finally, a verifying operation is executed to the each memory block to ensure that all the memory cells of the each memory block have the threshold voltages lower than the upper limit.

Abstract: Described herein are apparatus and method to measure a gap width distance, specifically the distance between a lip (4) of a coating hopper (1, 2, 4, 7) and a tangential edge (5) of a coating roller (3, 5) or a support (8) carried thereon. The apparatus includes a long range microscope (10) coupled with a CCD camera (11) to provide a computer (13) with an image. From this image, the computer (13) calculates first and second derivatives of the light intensity values between each pixel and determines the pixel locations of the lip (4) of the coating hopper (1, 2, 4, 7) and the tangential edge (5) of the coating roller (3, 5) or support (8) thereon, and hence the distance therebetween.

Abstract: A package for housing integrated circuit chips that provides EMF shielding and thermal protection, while conforming to an industry recognized package outline, is provided. This EMF shielding and thermal protection is achieved by providing an electrically conductive heat sink (10) that provides heat dissipation and that, together with a separate electrically conductive layer (12), also acts as an EMF shield. The heat sink (10) contains a recess (11) and is positioned against the conductive layer (12) with the recess (11) facing the conductive layer (12). The integrated circuit (8) resides inside the cavity formed by the heat sink (10) and conductive layer (12) and is protected from EMF by the heat sink (10) and conductive layer (12). The heat sink (10), electrically conductive layer (12) and IC (8) are then encapsulated in an electrically insulating molding compound (34) that is molded to an industry recognized package outline. Additional ICs (38) can be housed in this package by attaching them to the side of the electrically conductive layer (12) opposite the heat sink (10). These additional ICs (38) are protected from EMF emanating from the IC (8) that is housed inside the cavity. This allows for the possibility of housing EMF-generating components and EMF-sensitive components in the same package.

Abstract: The present invention provides for a method for assuring consistency between data and parity in a independent access disk array system following a system reset or a power failure condition which interrupts the execution of one or more disk write I/O operations. The method includes the steps of: examining current drive activities to identify unfinished write I/O operations in response to the receipt of a reset signal from a host system or a low power warning signal from a uninterruptable power supply (UPS); logging information necessary to identify the unfinished write I/O operations and the array redundancy groups associated with the unfinished write I/O operations into a non-volatile memory; and checking for log entries in the non-volatile memory during a disk array subsystem initialization following the system reset, or the restoration of power following a power failure. For each one of the unfinished write I/O operations identified in the log, the method further includes the steps of: performing a bit-wise exclusive-OR of corresponding portions of the data stored within the redundancy group associated with the unfinished write I/O operations to calculate parity consistent therewith; and writing the calculated parity to the parity storage areas within the redundancy group associated the unfinished write I/O operation. For an array operating in a degraded mode, i.e., operating with a failed disk drive member, the method also logs information necessary to identify the data and parity data storage areas to which the unfinished write I/O operations map new data and parity, and some form of the old data and parity information saved to the data and parity data storage areas to which the unfinished write I/O operations map new data and parity. Following the system reset, or restoration of power, consistent parity is determined for each redundancy group associated with an unfinished write I/O operation by combining the old data and parity saved to the non-volatile memory with the data currently stored within the data storage area to which the unfinished write I/O operation maps new data.

Abstract: Activated carbon is prepared specially by means of activating carbonaceous material in a circumstance comprising water vapor less than 15 % on volume basis and providing the thus treated activated carbon to carry alkaline or alkaline earth metal sulfide in it. The thus prepared activated carbon or that carrying these compounds provide for a method of eliminating mercury and its compounds from liquid hydrocarbons substantially completely which are contained in it at a slight amount. Liquid hydrocarbons containing mercury or sulfur will harm catalysts which are often applied during processing such intermediates of petroleum products and petrochemical products. Thus the present method is advantageous to processing of such oil intermediates.

Abstract: A paper film laminate sealing tape for sealing a
corrugated board carton or other article fabricated of
recyclable material. The tape is composed of a base ply
formed of oriented synthetic plastic film whose opposing
surfaces are corona-discharge treated to render them
wettable and receptive to adhesives, and a paper face ply
cold laminated to the base ply by a water-based adhesive.
The exposed surface of the film base ply is coated with a
water-remoistenable adhesive, such as a starch, so that
when this adhesive is moistened in a tape dispenser, the
sealing tape can then be adhered to the carton. Since
the re-moistenable adhesive is coated on the film ply
which is water-impermeable, when this adhesive is
moistened with water it remains in a moistened state in a
condition to be applied to the carton for a controlled
"open-time" period. because of the strong bond between
the film base ply and the paper face ply which resists
delamination, the laminate tape adhered to the carton may
be stripped therefrom, so that the carton can then be
recycled or reused.

Abstract: A/F sensor (30) outputs a linear air-fuel ratio detection
signal proportional to the oxygen concentration in an exhaust gas
from an engine (10) upon application of a voltage. A computer
(20) controls the applied-voltage in a stoichiometric control
region, a lean burn control region, an atmosphere detection
region and a rich control region to have a fixed value such that
the change rate of the applied-voltage is reduced to be less than
that in other regions. In addition, when changing the voltage
applied to the A/F sensor (30), the computer 20 variably sets the
voltage change speed sequentially. Thus, the influence of the
capacitive characteristic of the A/F sensor (30) is eliminated.
