Abstract: In a capillary rheometer including: a furnace (20) comprising a plurality of furnace zones (22a-d) and having a sample bore (23e) with a capillary (25a) connected to the lower end thereof; a plurality of heaters (22h) for heating the furnace zones (22a-d) thereby to heat a sample in the sample bore; and a plunger (6) for extruding the heated sample through the capillary; a plurality of temperature sensors (31,32a,32d) are provided for detecting the temperatures of the furnace zones, and the temperature characteristics of the furnace zones related to the temperature of the inner wall of the sample bore are obtained and stored in a controller (61). With a set objective temperature level to which the sample in the sample bore is to be heated, the controller determines on the basis of the stored temperature characteristics data the temperature of each of the furnace zones corresponding to the set objective temperature level, and controls the heaters so that the temperature detected by each of the temperature sensors coincides with the determined temperature of the corresponding one of the furnace zones. A temperature measuring rod (50) is also provided, which is adapted for insertion into the sample bore to accurately measure the temperature of the inner wall of the sample bore.

Abstract: A method for determining accurately the migration velocities for use in seismic migration processing of seismic data. The method presorts the seismic data into common-offset sections (14). The common-offset data is then migrated repeatedly with a selected range of velocities (16-22). The migrated data for each velocity is further sorted into a common-image point profile (24). The correct velocity per depth may then be determined by either determining the least time moveout for the common-image point at each depth (26), or computing the semblance for each common-image point and each test velocity and selecting the largest semblance value.

Abstract: The clamping element comprises a rapid-adjustment device combined with a power amplifier. The power amplifier is enclosed by a rotatable adjusting sleeve (2) which engages, with an external thread (3), into an internal thread (4) of a housing (1) surrounding it. A first clamping member (5) is fixed in the adjusting sleeve (2) and a second clamping member (11) is rotatably arranged in the adjusting sleeve (2). Arranged between both clamping members (5, 11) are two clamping bolts (13). The clamping bolts (13) are supported on the second clamping member (11) at as small a distance (a) as possible from the adjusting-sleeve axis (A). An actuating and pull rod (10), connected to the second clamping member so as to be fixed in terms of rotation and tension is guided either through a central recess in the first clamping member or through two diametrically opposite, lateral recesses (9) in the first clamping member (5). The last-mentioned recesses (9) are of such size in the circumferential direction of the adjusting sleeve (2) that they permit a limited twist, sufficient for rotating the second clamping member (5) with respect to the first clamping member (11), of the actuating and pull rod (10) with respect to the adjusting sleeve (2). On rotation of the actuating and pull rod (10) in the clamping direction, the latter is first drawn axially into the housing by rotation of the adjusting sleeve.

Abstract: An object, typically photoconductor drum (2) is electrically charged by placing a contact charger member (1) in abutment with the object to be charged (2) and applying voltage between the contact charger member (1) and the object (2). Charging is effected by properly controlling the capacitance of the contact charger member (1), the capacitance of the object (2), and the applied voltage. A sufficient charged potential is achieved through the application of a relatively low voltage, while preventing ozone generation. The portion of the charger member (1) which is in abutment with the object to be charged (2) has a less or greater work function than the surface of the object and can be made by a conductive polymer or a polyurethane having a resistivity of 10⁴ to 10¹² Ω.cm.

Abstract: A data recording/reproducing apparatus uses a single recording medium (1) in which absolute address data are previously formed. Also, the data recording/reproducing apparatus has a first memory (21) for recording and a second memory (14) for reproducing. Audio data reproduced from the recording medium (1) is stored in the second memory (14) at a first transfer rate, and the audio data stored in the second memory (14) is sequentially read at a second transfer rate lower than the first transfer rate to be audio-reproduced, while audio data inputted from external is sequentially stored in the first memory (21) at the second rate and the audio data stored in the first memory (21) is read at the first transfer rate to be recorded on the recording medium (1). The aforementioned reproducing and recording operations are alternately repeated. Thus, the data recording/reproducing apparatus allows audio data recording operation to be concurrently performed during audio reproduction with the single recording medium (1).

Abstract: Several process flows are proposed for achieving suitable wafer backside conditions for a microfactory starting material. The backside conditions proposed here will be adapted for microfactory CMOS process flows based on multiple integrated rapid thermal processing (RTP) cycles. These backside conditions ensure repeatable RTP uniformity and easy pyrometry calibrations. The use of a highly doped layer near the wafer backside ensures zero infrared transmission and repeatable RTP-based process uniformity, particularly for the lower temperature RTP-based processes such as low pressure chemical vapor deposition silicon. Two backside layers are used (oxide and nitride) to prevent p+ outdiffusion and backside field oxide or gate growth. The backside condition disclosed prevent emissivity variations/drift during RTP.

Abstract: Apparatus for closing a circuit breaker of a circuit that carries a substantial current includes terminals (W1, W2, W12, W13, W14) for connection to an available source of electric power. The electric power available is typically 24 VDC, 48 VDC, 125 VDC or 120 VAC. An actuator including an electric motor M and a solenoid S both designed to operate on 24 VDC first cocks charging springs and then releases the charging springs to close the circuit breaker. A controller including a microprocessor U3 is connected to and derives power from the connected terminals and produces a pulse width modulated control signal (RUN; CLOSE) for controlling the actuator. The duty cycle of the pulse width modulated signal is adjusted in relation to the electric power supplied by the selected source so that the power supplied to the motor and relay function effectively as the required 24 VDC power. Sensors J1 sense the condition of the charging springs, a charging cam, the circuit breaker, etc., and prevent operation of the circuit breaker closing apparatus unless all conditions necessary to safe operation are satisfied.

Abstract: A method and apparatus for the production of colored glass includes the steps of diverting a stream of clear molten glass from at least one glass melting furnace to a color treatment chamber. A measured amount of a color additive is introduced to the molten stream of clear glass prior to entry into the treatment chamber. Cold or preheated cullet of a clear or selected color is added to a charging end of the treatment chamber. The treatment chamber is heated to melt the cullet and further heat the remaining feedstock. The molten mixture of cullet, clear glass and raw material color additive is stirred by pulsed bubbling within the treatment chamber to chemically and thermally homogenize the mixture. A second stirring zone is provided adjacent an exit end of the treatment chamber to insure complete chemical and thermal homogenization of the colored glass melt prior to glass forming. A bypass channel is provided at the exit end of the chamber to permit sampling of the treated glass prior to glass forming. A valve blocks the flow of colored glass from the outlet region of the chamber while sampling takes place permitting clear glass production to continue on the designated colored glass forming machine until the proper color is obtained. Heated valve members are positioned in the glass transport channels to regulate the flow rate and glass level and to provide selective shut off of individual glass streams.
