Title: Power circuit for different stabilized dc  voltages
Inventor: TANAHASHI MAKOTO
IPC: G05F1/56
Filed: 1978-06-15
Granted: 1981-11-17
Abstract: ABSTRACT OF THE DISCLOSURE         In a power circuit arrangement, there are a plurality of voltage stabilizers each including a reference voltage source, a circuit for comparing the output of the respective voltage stabilizer with a reference voltage, and a voltage control element responsive to the output of the comparing circuit.  The reference voltage for at least one of the voltage stabilizers is provided by an independent element, and the reference voltage-for the remaining voltage stabilizers is formed on the basis of the output voltage of the other voltage stabilizers.  When the output voltage of any one of the voltage stabilizers becomes zero, all of the other voltage stabilizers similarly have their output voltages reduced to zero.

Abstract: NOISE REDUCTION METHOD & APPARATUS    FOR COMPANDED DELTA MODULATORS           ABSTRACT    A noise reduction circuit and method are described for implementation in a delta modulation system for signal trans-mission.  Under certain conditions when the delta modulator has selected the minimum step size for encoding and transmission, the present technique and apparatus are effective to change the minimum step size in a way which prevents low level noise generation from occurring in the delta modulation system.  The technique and circuit can be utilized with most commonly available delta modulators which have means for changing the step size (i.e., the delta) but is used to the best effect on more stable implementations of delta modulators where an integrator is replaced by a digital accumulator and a digital-to-analog converter.

Abstract: ABSTRACT            This invention relates to an automatic lift device for use in association with doorway openings of buildings or of vehicles such as buses and vans so as to facilitate the loading and unloading of handicapped persons into and out of such buildings and/or vehicles. More specifically, the invention relates to an automatic lift device which consists of a lift carriage that is mounted within the doorway opening so as to be vertically movable therein. Movable step and riser elements are provided within the lift carriage so as to form normal upper and lower entrance steps in their retracted normal use position. The lift carriage is selectively movable to a lowered ground level position and a raised interior floor level position while the upper step and riser remain in their retracted normal step position within the lift carriage. The upper step and riser pivotally connected thereto are selectively extendable outwardly and downwardly so as to form a con-tinuous horizontal loading platform in association with the fixed lower step formed by the base of the lift carriage. Thus formed, the horizontal loading platform can be selectively lowered to the ground or curb level or to any level intermediate thereto.  It can be also selectively raised to the interior vehicle floor level thereby enabling a handicapped person, on crutches or in a wheelchair, to easily board or disembark from such vehicles at will.  The riser element which is pivotally connected to the movable upper step can be selectively raised to form a ramp extension of the loading plat-form.  The riser is pivotally movable from its ramp extension position so as to automatically compensate for uneven ground so as to facilitate movement of a wheelchair onto the loading platform.  After a wheelchair has been moved onto the loading platform, the riser can be selectively pivotally moved to a position above the horizontal so as to act as a guard against inadvertent movement of the wheelchair from the platform while the platform is being raised to the level of the vehicle inside floor.

Abstract: MOVING CONTACT FOR RADIAL BLOW-IN EFFECT FOR            ARC SPINNER INTERRUPTER          ABSTRACT OF THE DISCLOSURE         A contact construction is disclosed for a circuit interrupter of the type in which an arc drawn between cooperating arcing contacts is caused to cir-culate around an axis and through a dielectric gas in order to extinguish the arc.  The movable contact is so constructed that the current path is directed radially relative to the contact axis so that a magnetic force is applied radially inward to the arc which roots on the movable contact.  This magnetic force tends to move the arc root on the movable contact to the innermost radial position on the movable contact.  The arc is also forced in a direction away from exteriorly positioned main contact components.

Abstract: ABSTRACT OF THE DISCLOSURE         A method according to the present invention is intended for treating articles for magnetically soft alloys employed in radio-electronic, relay and switching apparatus, in optical-and-mechanical and automation systems.  The method consists in sa-turating the surface of the articles with chromium inside a powder chromizing mixture at a temperature in excess of 800°C, the articles being heated at a rate not higher than that of re-crystallization of a metal of the articles and the rate of dif-fusion processes of saturating the articles.  The articles are cooled at a rate close to that of phase transformations and for-mation of a magnetic structure in the metal of the articles, for example, at the rate of 20-200 degree/hour below the Curie point.  To enhance the magnetic properties and the stability thereof,  as well as wearability and the resistance of the items to corrosion, chromizing of the article surfaces is conducted in an inert gas atmosphere.

Abstract: ABSTRACT OF THE DISCLOSURE    Apparatus is provided for cutting and metering slabs or bales of unvulcanised rubber to be fed to a single rubber mixing machine.  The apparatus includes a conveyor belt and a carriage arranged to transport bales of rubber along parallel paths.  A cutting machine is positioned to cut a slice off a bale carried by said carriage.  By arranging for the carriage to undergo back and forth movement while intermittently effecting transverse feed of the bale, the cutting machine cuts a succession of slices off the one bale.  To make up a load of rubber of a required weight, whole bales are transferred to a hopper via the conveyor belt until a weighing machine indicates that the required weight has almost been reached;  thereafter the cut slices of rubber are added to the hopper under the control of the weighing machine to make up the weight required.
