Title: Multicolour voltage tunable quantum well intersubband infrared photodetector and associated method
Inventor: LIU HUI CHUN
IPC: H01L31/0352
Filed: 1994-07-07
Granted: 2003-12-02
Abstract: A quantum well intersubband infrared (IR) photodetector has a spectral response tunable by an external voltage. The photodetector consists of multiple doped quantum wells with different well widths and barrier heights. The preferred embodiment is made by repeating the whole structure of the active region of a multiple quantum well intersubband IR photodetector. Differences between repeats or groups of well widths and barrier heights result in differences in the spectral IR response of the different repeats. The device resistance of a given group is designed to be very different from those for all the other groups. As a function of an applied voltage, the repeat with the highest resistance will be turned on to detect IR with the response peak at a wavelength .lambda.1. Subsequently, the next highest resistance repeat will turn on when increasing voltage with its response peaked at .lambda.2, and so on. Since .lambda.1, .lambda.2 are different from each other, a voltage tunable multicolour photodetector is realized.

Title: Electrolyzed water producing method and apparatus
Inventor: ARAI KAZUYOSHI
IPC: C02F1/46
Filed: 1994-07-28
Granted: 2005-02-22
Abstract: Tn a batch type electrolyzed water producing method, a first run of electrolysis is carried out, and electrolyzed water is discharged. Thereafter, before a next run of electrolysis is carried out, the polarity of a DC power source connected to the electrode plates is reversed. Thus, the electrode plate which has served as a cathode plate in the last run of electrolysis is converted into an anode plate and therefore, deposits accumulated on the electrode plate are ionized and dissolved into the subject water.

Abstract: A method of completing multi-lateral wells and maintaining selective re-entry into laterals is presented. In accordance with the present invention, a first lateral well (16) is drilled from a primary well bore and a string of external casing packers (22) and a packer bore receptacle (26) are run therein. Once the orientation of the packer bore receptacle (26) is determined, an orientation anchor (28) of a retrievable whipstock assembly (50) is mounted thereto. Thereafter, a second lateral well (72) may be drilled. Once the second lateral well (72) is drilled, the whipstock assembly (50) may be retrieved and replaced with a scoophead/diverter assembly (91,92) which also includes an orientation anchor (99) for mating with the packer bore receptacle (26). At this time, a string of external casing packers (103) may be run into the second lateral well (72) through the scoophead (92) diverter (91) assembly. Finally, a selective re-entry tool (120) is run into the scoophead assembly (92). The selective re-entry tool (120) includes a diversion flapper (184) for selecting either the first (16) or second (72) lateral well bore. Selective re-entry is desirable for the purpose of perforating well intervention techniques. The re-entry tool (120) tray be actuated by a device located on a coil tubing work string which may be operated from the surface.

Abstract: An aqueous rinse-aid composition for kitchen utensils is provided wherein an anionic hydrotrope and a blend of two specifically defined nonionic surfactants are utilized which has been shown through empirical research to surprisingly yield improved results. One of the nonionic surfactants is an alcohol alkoxylate (as defined) and the other nonionic surfactant is a block copolymer of ethylene oxide and propylene oxide (as defined). The composition is suitable for use at a temperature of up to at least 180°F. in the absence of excessive foaming, spotting and film formation. The components of the composition exhibit good compatibility during storage even if elevated temperatures are experienced thereby maintaining reliable performance upon usage. Rapid high velocity rinsing at a high temperature is made possible in the absence of deleterious foam generation to yield dishes and tableware that can be readily dried without the need for the time consuming hand removal of deleterious spots and/or film.

Title: Apparatus and method for transferring and storing data from an arbitrarily large number of networked computer storage devices
Inventor: KULLICK STEVEN E
IPC: G06F12/00
Filed: 1994-01-19
Granted: 2001-08-07
Abstract: This invention provides a method and apparatus for storing on centralized mass storage devices archival data from multiple computers in a networked environment. In a networked computer system having a communication network interconnecting one or more computers and a storage unit, parallel processes are created to perform repeated backup operations for disks on computer devices on the communication network.  A storage unit may be a single storage device capable of executing a plurality of processes or one or more primary storage devices connected to one or more secondary storage devices.  The backup operations for a disk include a backup initialization which occurs when a primary storage device does not have a full index or a backup data file for a disk but a secondary storage device does. During a backup initialization, data from the files and directories on that disk along with an index entry for each file or directory are passed to the primary storage device which directly passes that information directly through to the secondary storage device. The index entries are incorporated into a full index and the data is incorporated into a backup data file. An index entry contains, among other information, the location of a file or directory on the disk, the date the file or directory was last modified and the location of the associated data in the backup data file.     During a backup cycle, the computer device is incrementally backed up to a primary storage device such that the primary storage device contains a full index with an entry for each file and directory on the disk and a backup data file for the disk with data for the files and directories which have been changed or created since the last backup to the secondary storage device occurred. When a specified, predetermined time or event occurs or the transfer is otherwise indicated, the primary storage device transfers the full index and the backup data file to the secondary storage device.

Abstract: This invention provides a separation method for an adhesive tape and a separation device that can reliably and efficiently perform the operation of removing the backing sheet from the adhesive sheet of the adhesive tape and can be automated with a simple structure. The adhesive tape comprises a base sheet, an adhesive sheet which is applied to the base sheet and a backing sheet laminated to the base sheet. According to the invention, one end of the adhesive tape is supported leaving that end as a free end. Separation means is used to bend the free end in the direction from a first surface of the adhesive tape to a second surface of the adhesive tape until slippage occurs between the adhesive sheet and backing sheet. While in this state, the separation means is withdrawn from the adhesive tape as it traces the end surface at the free end. Thus, the backing sheet is removed from the adhesive tape and can be affixed to an object.

Abstract: Pullulan is precipitated from an aqueous solution by mixing with a hydrophilic organic solvent incapable of dissolving pullulan. Solid pullulan is then separated from the liquid component of the dispersion by feeding the dispersion into a V-type disk press having a pair of discoid screens arranged so that the distance between them decreases as they are rotated. The pullulan dispersion is pressed by the discoid screens, recovering the liquid component through the screens. The resulting low-liquid-content pullulan continues to rotate together with the screens to an outlet, where it is discharged from the press.

Abstract: A wheelchair incorporates a tilt mechanism with a center of gravity compensation by employing a rotary actuator. The actuator is secured to the underside of the seat and has an arm pivotally secured to the frame. A seat pivot axis is located on a movable member that allows the axis to shift from a rear portion of the wheelchair toward a front portion as the seat is tilted from its upright position to a tilted position. This assures that the center of gravity of the user is maintained within the wheelbase of the chair, i.e., compensates for center of gravity.
