Abstract: The present invention is a class of polyimide membranes containing copolymerizable, surface modifiable units containing both aromatic diamines and alkenylated diamines having an allyl or allylaryl group preferably positioned ortho to an amine functionality. The polyimide membranes can be surface modified by treatment with an activating force such as high energy electromagnetic irradiation or with a free radical source to impart high selectivity to the membrane without causing a large decrease in composite permeance.

Abstract: A differential gear mechanism has a clutch (8) formed and acting between a pair of worm gears (2,3) each of which are connected to different axle shafts (13,14). The clutch (8) releasably inter-connects the worm gears (2,3) to lock the differential.

Title: New and improved, ultra low carryover sample liquid analysis apparatus and method.
Inventor: UFFENHEIMER KENNETH F
IPC: G01N35/10
Filed: 1989-11-17
Abstract: The sample liquids analysis system includes a probe which is automatically operable to successively aspirate sample liquids and reagent and/or other sample liquids processing liquids and to dispense the same in turn into sample liquids analysis apparatus for automatic, successive sample liquids analyses. Isolation liquid supply apparatus are operatively associated with the sample liquids aspirating and dispensing probe and operate to introduce an isolation liquid which is immiscible with the sample liquids and which selectively wets the probe to the substantial exclusion of the sample liquids, to the probe to, in combination with operatively associated rinse liquid supply apparatus which operate to fill the probe with a rinse liquid between successive sample liquids aspirations, reduce sample liquids carryover to ultra low levels. The sample liquids aspirating and dispensing probe are operated by the rinse liquid supply apparatus; and comprise a probe body member, and an active probe component operatively connected thereto by a readily disconnectable connector, thus making possible the ready and convenient replacement of the active probe component without adverse effect upon the essential configuration and/or operational characteristics of the rinse liquid supply apparatus, and thereby upon the overall performance of the sample liquids analysis system. The configuration of the probe operates to reduce sample liquids flow velocity in the active probe component, thereby further reducing sample liquids carryover.

Title: Raster scan control system for a charged-particle beam.
Inventor: YOUNG PHILLIP E
IPC: G21K5/04
Filed: 1990-03-30
Abstract: A raster scan control system (18) for use with a charged-particle beam delivery system (20) provides precise control of large currents driving an inductive load. The beam delivery system includes a nozzle through which a charged-particle beam (24), such as a proton beam, passes prior to being directed to a target (32). The nozzle includes both fast and slow sweep scan electromagnets (204, 208) that cooperate to generate a sweeping magnetic field that steers the beam along a desired raster scan pattern at the target. The electromagnets are driven by large currents (213, 215) from the raster scan control system. The raster scan control system includes both fast and slow power amplifiers (212, 214) for delivering the desired large currents to the fast and slow electromagnets, respectively; monitoring means (206, 210) for monitoring the magnetic fields; sensing means (212, 230) for sensing the large currents; feedback means for maintaining the magnetic fields and large current at desired levels; out of tolerance means for automatically causing the servo power amplifiers to steer the beam away from the target area in the event the error signal becomes excessive; a programmable raster generator (80) for providing the fast and slow power amplifiers with a raster scan signal (216, 218) that defines the desired raster pattern; and a power supply (74) for delivering the requisite power to the power amplifiers and other components.

Abstract: A photoconductive layer (5) of a photosensitive member (1) and a charge retaining layer (6) of a charge retain medium (2) are so disposed as to face each other with a predetermined distance (d). After a power source (8) is connected, light (9) having a predetermined wavelength is irradiated to the photosensitive member (1) to form an electrostatic latent image in the charge retaining layer (6) of the charge retaining medium (2). Next, the charge retaining medium (2) is disconnected from the power source (8), toner is applied onto the charge retaining layer (6) and development and fixing are carried out. Etching is then conducted using the resulting toner image (16) as a mask to remove the portions of the charge retaining layer (6) to which the toner (16) is not deposited. In this manner a printing plate having a scanned portion formed by the toner (16) and the charge retaining layer (6) on the conductive substrate (7) can be obtained. According to this plate, the toner image is formed directly on the charge retaining layer (6) of the charge retaining medium (2). Therefore, the toner image need not be transferred and a scanned portion having high resolution can be formed.

Abstract: In a hand-held drilling machine with a combination chuck for the alternative chucking of round-shank or slotted-shank tools, the insertion, the automatic locking and the holding of slotted-shank tools is to be simplified and operating errors are to be eliminated. This is achieved by the receptacle (35) for slotted-shank tools (10) being arranged behind the chucking area of the jaw chuck (16) as viewed in the axial direction from the insertion side (18) of the tool holder (8). This type of construction permits the attachment of means (22) for the rotary driving of the inserted tool. If a hammer drill is equipped with the tool holder (8) according to the invention, the concentric-running properties in round-shank drill bits are thus also considerably improved thereby. <IMAGE>
