A decoding circuit comprises an m row by n column matrix arrangement of transmission gates, wherein an output terminal of one of two mutually adjacent transmission gates in each column of the matrix arrangement is connected to an input terminal of the other of the two mutually adjacent transmission gates, input terminals of the n transmission gates in a last row are connected to a high voltage source, output terminals of the n transmission gates in a first row are connected to a low voltage sour...

A multiple station/multiple user exercise device having grasping sites for performing seated or kneeling chin-ups, situps, seated dips, and inclined pushups, the exercises necessary for overall physical fitness. The device is arranged so each site may be used by an individual concurrently with any other individual's use of another site, with as many as seven individuals using the device at any one time. The device is made from aluminum tubing and is inexpensive to manufacture and to transport. T...

In a multiple output multiple step-up rectifier circuit of the invention, an output voltage of a power source circuit is supplied to a plurality of Crockroft-Walton multiple step-up rectifier circuits connected in parallel with each other. The capacitor capacitance ratio of the rectifier circuits is proportional to the ratio of the numbers of multiplication stages of respective rectifier circuits. Particularly, when the squares of the number of multiplication stages is comparatively large, the c...

A multiple column multiple choice vending machine having a respective vending gate for each column with removable or selectable diverting means to divert some articles stored in one column to an adjacent column to be vended by the adjacent column vending gate while permitting other articles store in the one column to be vended by the one column vending gate thus increasing capacity for favorite articles without reducing the total choice of articles.

A multiple regeneration multiple absorption type heat pump having a multiple absorption system and a multiple regeneration system and adapted so that a refrigerant and an absorbent are circulated between the two systems and so that a fluid to be heated is passed therethrough the multiple absorption system comprises an evaporator for evaporating the refrigerant by a heat from an external low-temperature heat source, at least one absorbing/evaporating unit for allowing the absorbent to absorb the ...

A three modulus prescaler for a phase-locked loop frequency synthesizer includes a N.sub.0 modulus prescaler inputting into a divide-by-two circuit. A microprocessor and internal logic control a three modulus prescaler synchronizer to receive signals from the divide-by-two circuit and output control commands to the N.sub.0 modulus prescaler so as to cause the N.sub.0 modulus prescaler to divide solely by a first or second modulus, or alternately between said first and second modulus, between out...

A real-time magnetic digital video disk recording system has been developed for applications in on-line digital imaging systems and off-line fast access image storage and retrieval buffers. The disk recorder uses new high density recording technology and Winchester computer drive technology in a unique peripheral configuration which is fully synchronized to video system timing, provides for flexible formatting, achieves fast random access to a large video image file, and eliminates the need for ...

In medium to high volume printers using more than one print head, multiple documents may be printed side by side in one pass. Multiple rolls of ribbon are utilized on the ribbon mandril to accommodate the documents. The ribbon is kept taut across its print head by the feed system controller. When the outside diameters of the two rolls of ribbon vary, the system keeps one ribbon taut and the other tends to go slack at the print head. A split sleeve mandril with a differential mechanism connecting...

A multiple battery, multiple rate automatic switching battery charger is disclosed. Two or more batteries are charged sequentially in a multiple pocket battery chargers in order to maintain a low peak power consumption level. One battery pocket is assigned a priority so that a battery placed therein will be charged first at a fast rate of charge. Upon completion of the fast charge cycle, the priority battery can be trickle charged during the fast charge of the non-priority pocket battery.

A multiple compartment refuse container is provided wherein the compartments have doors both at the top and at the sides of the compartment structure. The refuse container may be used with plastic bags which are easily fastened inside of the container or it may be used with conventional garbage cans. The user of the container merely lifts the top and drops refuse therein and the container is easily emptied by means of side doors. The container is ordinarily built in two or four compartment model...
