Abstract: A plasma etch chemistry which allows a near perfectly vertical etch of silicon is disclosed. A Cl-containing compound such as BCl<sub>3</sub> has Br<sub>2</sub> added to it, readily allowing anisotropic etching of silicon. This is due to the low volatility of SiBr<sub>4</sub>. The silicon surface facing the discharge is subjected to ion bombardment, allowing the volatilization (etching) of silicon as a Si-CI-Br compound. The Br which adsorbs on the sidewalls of the etched silicon protects them from the etching. This new plasma etch chemistry yields a very smooth etched surface, and the etch rate is relatively insensitive to the electrical conductivity of the silicon.

Abstract: A grain-oriented silicon steel sheet having high magnetic induction and low iron loss can be produced by controlling properly the particle size of carbide precipitated in the crystal grains of the steel sheet before final cold rolling. Further, the magnetic properties can be more improved by adjusting the C content in a starting silicon steel depending upon the Si content in the steel and removing a proper amount of C from the steel during the course after completion of hot rolling and before final cold rolling, in addition to the proper control of the particle size of carbide precipitated in the crystal grains of the steel sheet before final cold rolling.

Abstract: A longitudinally displacable roll apparatus supporting a web (16) of record material is designed to maintain the roll (18) in proper alignment with associated processing equipment as the web is paid from, or wound onto, the roll. The apparatus comprises a pair of frame members supporting the roll. The roll is rotated by a drive shaft (195) having an interengageable coupler on the drive shaft and one end of the roll, to permit the roll to be rotatably driven by the roll drive shaft while not being directly secured thereto. The other end of the roll is engaged by means for displacing it longitudinally in accordance with signals derived from the actual path of the web so as to keep the web accurately on its intended path. The longitudinal and rotational drive system are able to operate independently of each other.

Abstract: Secretin, which cannot be prepared directly by genetic engineering because of its carboxylic acid carboxyl-terminus, can be obtained by preparing secretylglycine by genetic engineering and then obtaining secretin therefrom by enzymatic conversion of the terminal glycine radical. The gene for the secretylglycine is synthesized chemically from smaller single-stranded units which are linked enzymatically to give the complete gene, incorporated into a suitable vector and amplified therein, after which the peptide is isolated directly or as a fusion protein and, after cyanogen bromide cleavage, is converted enzymatically into secretin.

Abstract: A regenerative liquid propellant gun structure in which the differential area piston is annular, having a peripheral cylindrical skirt extending away from the combustion chamber to define a propellant reservoir, and has an aperture permitting overrunning of a fixed bolt. The fixed bolt is shaped to define with the edge of the aperture a variable annual orifice for propellant injection as the piston moves. There is a second free piston overruning the bolt and mating with the inside of the differential area piston to complete and provide for emptying of the reservoir. The structure also contains a spring to allow components to move responsive to increased combustion chamber pressure to provide for an initial movement of differential area piston relative to the bolt to start propellant injection and a fluid pressure means for movement of pistons after firings to facilitate reloading.

Abstract: A diagnostic system for use in a raster scan type cathode-ray tube (CRT) display device is described in which a predetermined portion of a video output signal is sampled in timed relationship with multiple reference timing signals. Known character and character-attribute information is stored in a random access memory (RAM) under diagnostic program control at a location corresponding to a character location on the display screen. The data stored in the RAM is output to the display circuitry in response to the reference timing signals. The video output signal of the display circuit is coupled to a data latch that samples the video signal corresponding to the location of the character and character-attribute information stored in the RAM. The sampled data is coupled to a micro-processor where a comparison is made btween the sampled data and a predetermined value to verify the proper operation of the circuit.

Abstract: A disc brake comprises a fixed support 11 arranged to one side of a rotatable brake disc (not shown). A guide pin 15 is slidable in the support and extends parallel to the disc axis. First and second friction pads 33 and 34 are arranged one to each side of the disc. A caliper 18 has an hydraulic actuator 23 located on the same side of the disc as the support; the actuator thrusts the pin against the first pad and thereby thrusts that pad into frictional engagement with the disc during application of the brake. The caliper has two arms 19 which extend across the periphery of the disc to a reaction support 21 for the second pad 34 to bring it into frictional engagement with the disc on operation of the actuator. The first pad 33 is constrained against rotation with the disc by its engagement with the pin 15. The second pad 34 is constrained against rotation with the disc by its own engagement with the caliper 18 and by engagement of the caliper with the first pad which in torn is located by pin 15. Further constraining means including small pin 45 supported in caliper lugs 47 and 54 and in lug 49 of support 11 prevent tilting of the caliper with respect to the support.

Abstract: A wire-cut electric discharge machining apparatus causes an electric discharge between a wire and the work while supplying a working fluid to the area therebetween thereby machining the work. The apparatus has a means for controlling the flow rate of the working fluid. When the machining electric discharge energy is decreased due to a reduction in the machining speed at a corner machining portion or circular machining portion, the flow rate, that is, the pressure of the working fluid is reduced, thereby preventing vibration of the wire.
