Abstract: ABSTRACT OF THE DISCLOSURE            A semiconductor optical image sensing device having a signal line connected to drain electrodes of MOS field effect transistors each corresponding to a picture element, wherein source electrodes of the MOS field effect transistors are connected to photo-diodes, capacitors of MOS structures are connected between gate electrodes of the MOS field effect transistors and a noise line, and the signal line and the noise line are connected to input terminals of a differen-tial amplifier. The capacitors of MOS structures are formed in the same way as the gates and drains of the MOS field effect transistors. By applying a scanning pulse to the gate electrodes of the MOS field effect transistors to scan the MOS field effect transistors for switching the same, a signal output and a noise output are produced from the signal line while another noise output is produced from the noise line. Signal to noise ratio can be enhanced by producing only the signal output from the differential amplifier.

Abstract: ABSTRACT OF THE DISCLOSURE           A vibration resistant threaded fastener which may be a set screw or any other type of threaded fastener wherein the load bearing flank of the thread surface of the screw is pro-vided with a series of serrations,  Each serration is formed with an inclined ramp terminating in a buttress with the ramp surface being inclined in the direction of tightening the fast-ener so that the buttress presents a surface tending to act against rotation of the fastener to preclude loosening of the fastener.  Upon engagement in a workpiece under compressive load the buttress of the serrations coact with the thread flank of the mating internal thread in a workpiece to preclude dis-engagement of the fastener.  In one embodiment of the fastener bearing pads are provided to limit the degree of coaction between the serrations and the thread flank of the workpiece.

Abstract: ABSTRACT      The disclosure concerns hydrostatic supporting apparatus which supports, without physical contact, a mobile part which moves relatively to a load-bearing part.  The apparatus comprises a supporting piston which has at least one hydrostatic bearing pocket which provides a pressure cushion through which the mobile part is supported, and which is urged toward the mobile part by a controlled pressure which increases and decreases, respectively, as the piston moves toward and away from the load-bearing part.          Preferably, pressure control is effected by a throttle valve interposed either in a supply path leading from a source of pressure medium to the pressure chamber of a hydraulic supporting motor, or in a feed passage leading from that pressure chamber to the bearing pocket.  The pressure cushion of the supporting piston may act directly upon the mobile part, or it may carry an auxiliary hydrostatic supporting element which has its own supply of pressure medium and provides a second pressure cushion which actually supports the mobile part.  The apparatus may also include a safety device which serves to maintain supporting pressure for the piston upon failure of the main pressurizing circuit.

Abstract: Abstract of the Disclosure The specification discloses image forming particles for use in electrostatic image formation.  Each of the particles has light transmitting properties and includes a particles defining material containing properties and includes a particle defining material containing an electrically conductive material and a substance capable of subliming when heated. The electrically conductive, translucent particles enable charge preliminarily imparted to a photoconductive support member to be readily erased upon exposure to light from an original, with consequent reduction of the electrostatic attraction between the particles and the support member to a minimum for obtaining a clear and definite image without fogging. Furthermore, the particles are electrically independent due to an absence of electrostatic attraction therebetween because of their electrical conductivity.  Thus, the particles adhere to the support member by electrostatic induction of the charge imparted to the latter without adhesion between the particles, and the particles can be arranged uniformly on the support member in a single layer and as close to each other as possible, thereby producing a resulting image of still high quality.
