Abstract: Abstract: Device for photolithographically treating a thin substrate.        A device for photolithographically treating a thin substrate comprises pre-alignment station, a substrate-supporting table and a transport arm which is provided with a vacuum connection for holding the substrate by suction at its lower side during transport of the sub-strate from the pre-alignment station to the substrate table. The sub-strate table is provided with supporting means for the substrate which are adjustable in the direction of height and which have a supporting surface which is adjustable to a distance above the substrate table exceeding the thickness of the transport arm and is adjustable in a downward direction at least through a distance such that the supporting surface is level with the upper surface of the substrate table, the supporting means leaving a space free for the movement of the transport arm above a part of the substrate table.

Abstract: ABSTRACT OF THE INVENTION        A directional face plate for a display device is provided in which the face  plate  itself  is made of  a fiber optic media  (13). Optical  images produced on an inside surface (25) of the face plate (13) are transferred and reproduced at an outside surface (16).  This enables a geometric directional filter (26) to be placed directly on a surface (16) upon which an image is produced.  The fiber optic face plate (13) provides a certain amount of directional filtration and therefore enhances  the  effect  of  the  directional  filter  (26),  as  well  as permitting the geometric directional filter (26) to be placed directly on  an  image bearing  surface  (16).   Further  advantages  include  the ability to provide a flat geometric filter  (26) while ignoring the effects  of  placing  an  image generating  substance  (14)  on a curved surface (25').

Abstract: SPEED-RESPONSIVE REVERSING HYDRAULIC               DRIVE FOR ROTARY SHREDDER               ABSTRACT OF THE DISCLOSURE           A hydraulic drive for a rotary shredder includes a rotation-actuated electric reversing con-trol.  Such control includes a rotation sensor posi-tioned on one of the rotational elements of the drive: one of the cutter shafts, the hydraulic drive motor shaft or the hydraulic pump motor shaft.  An RPM monitor circuit receives a signal from the rotation sensor and measures rotational speed to determine existence of a stoppage or slowing of the shaft corresponding to a jam-ming condition.  This circuit monitors shaft speed over discrete time intervals and discriminates between momentary jamming conditions by determining the duration of low shaft speed conditions.  The circuit transmits a jam signal to a reversal actuator circuit upon detection of a subnormal shaft speed persisting longer than the predetermined time interval.  The reversal actuator cir-cuit includes a timer and reverse and forward solenoids on a flow-reversing valve for briefly reversing fluid flow to the hydraulic motor when a jam signal is received.  Monitoring rotation at the pump motor enables the hydraulic fluid circuit, including a pressure relief valve, and the pump motor to filter out brief changes in rotation due to momentary jamming conditions and thereby aid in discriminating between true and momentary jamming conditions.

Abstract: ABSTRACT     A multiplexer has a plurality of bandpass filters coupled through E-plane or H-plane T-junctions to a waveguide manifold.  Where the multiplexer has four channels and each filter is a six-pole filter, two triple mode  cavities  make up each filter.  Where each filter is a five-pole filter, one triple cavity and one dual mode cavity makes up each filter.  Two band edge channel filters- are operated to produce an asymmetrical filter function response, thereby causing extra trans-mission zeros to be created and improving the select-ivity of the filter out of the passband.  The multiplexer is designed for use in satellite communication systems and can have a reduced volume and weight when compared to previous multiplexers without any sacrifice in electrical performance.

Abstract: VIBRATION ISOLATING COUPLING           Abstract A vibration isolating coupling ideally suited for coupling the bobbin (31) of a linear actuator (23) to a flexure supported printer carriage (11) is disclosed. The two main sources of vibration in a system that includes a flexure (13, 15) supported carriage coupled to a linear actuator (23) are low-frequency vibration resulting from the pivot arc motion of the flexures (13, 15), and high frequency vibration resulting from the change in bobbin shape occurs asAC energy is applied to the bobbin (31). The first source of vibration is reduced by configuring the interface plane between the linear actuator and the flexure supported carriage such that contact occurs at spaced apart points located on either side of the flexure movement plane. Preferably, four contact points equally spaced from the flexure motion plane are used. The region between the contact points and the flexure motion plane is cut out so that no contact occursin and on either side of the flexure motion plane. It is the absence of contact that reduces the first source of vibration. The second source of vibration is reduced by mounting a damping plate (61), preferably comprising a layer of viscoelastic material sandwiched between two layers of steel or some other rigidmaterial, at the interface plane between the linear actuator (23) and the flexure supported carriage (11).

Abstract: AUTOMATIC DEFROST SENSING ARRANGEMENT FOR MICROWAVE OVEN        ABSTRACT OF THE DISCLOSURE         A system and method for defrost detection particularly applicable to a microwave oven having an excitation system which normally exhibits relatively little change in voltage standing wave ratio and phase for loads of widely varying dielectric constant values.  A discontinuity is periodically introduced into the waveguide coupling microwave energy from the source to the cooking cavity.  This discontinuity is effective to cause a substantial change in the magnitude and phase of the electromagnetic field in the waveguide for food objects in the frozen state, while causing relatively little change in these parameters for the same food objects in the thawed state.  Hence, the presence of the discontinuity in the waveguide provides a readily detectable difference in field strength at the sensor location in the waveguide between an object in its frozen state and the same object in its thawed state.  A sensor responsive to the strength of the electromagnetic field at a predetermined location in the waveguide generates an output signal representative of field strength at that location.  This output signal is sampled with the discontinuity present in the waveguide to detect a predetermined relationship between the signal and a reference which when detected indicates the food load has converted from its frozen state to its thawed state.

Abstract: ABSTRACT OF THE DISCLOSURE          A curtain wall (12) used to divide the shaft in a shaft construction (10) is made of panels (26) in the shapes of parallelograms.  Side edges (28 and 30) of the panels (26) are received in channels (18 and 20) in the peripheral wall (16) of the shaft construction.  The side edges are parallel to each other, and the perpendicular projections of each side edge are substantially non-overlapping with the other side edge.  The result is that the panels can be lowered lengthwise into place and then rotated into the proper orientation.  The panels can therefore be lowered through smaller openings than rectangular panels can, and they do not have to be lowered by "chivvying," as rectangular panels do.

Abstract: ABSTRACT           An electronic device measurement apparatus measures a characteristic of an electronic device under test(DUT) by applying a sine-wave voltage to the DUT,detecting a voltage across the DUT and a current flowing through the DUT and displaying a characteristic curve in accordance with the detected voltage and current.          Since the sine-wave voltage is generated in phase with an AC line voltage and an amplitude thereof is independent of the line voltage, each of circuits in the measurement apparatus is not affected by variation of the phase and amplitude of the line voltage.  Moreover, the sine-wave voltage is symmetrical, so that a display distortion can be eliminated.
