Abstract: An ink-jet printer uses droplets of conductive ink to print on a recording medium. The ink is in a chamber having a nozzle and a piezoelectric member attached to one wall of the chamber. The droplets are driven out of the nozzle in response to a driving pulse which is applied to the piezoelectric member. The size of the droplets is determined by the energy content of the driving pulse. The charges formed upon the droplets leaving the nozzle are generated responsive to the driving pulse and have a level which depends upon the driving pulse.

Abstract: Upon applying a discharge voltage between opposed electrodes of a plasma display panel, all electrodes other than a selected electrode are clamped at a fixed potential. To that end, a toggled voltage is supplied from a toggled voltage source and applied via a first switching circuit, to one ends of a plurality of second switching circuits in common. The other ends of the second switching circuits are respectively connected to panel electrodes and to one end of third switching circuits. The other ends of the third switching circuits are respectively held at a fixed potential. The second and third switching circuits may be driven synchronously in such manner that when one is ON, the other is OFF and vice versa when a toggled voltage is not brought to a panel electrode, that panel electrode is clamped at a fixed potential. Such a first switching circuit and a group of second switching circuits are combined into one set.

Abstract: Frequency modulators for use in microwave link transmission systems include acoustic surface wave (ASW) oscillators. Each frequency modulator comprises two voltage control quadripole ASW oscillators. Control inputs of the two ASW oscillators receive modulation signal in opposite phase. Outputs of ASW oscillators are mixed in a mixer for delivering an IF signal. Thus frequency deviation is larger than in a conventional arrangement. Moreover, surface wave oscillators make it possible to directly insert a service channel signal in a microwave link repeater, without demodulation and modulation operations.

Abstract: A constant-current circuit is especially well-suited for construction as a semiconductor integrated circuit, and it is stable over a wide range of variations in power potential. The constant-current circuit produces first to third biasing potentials. A first current source produces a first current responsive to the first bias potential. A second current source produces a second current responsive to the second bias potential, and a third current source produces a third current responsive to the third bias potential. A constant current output is obtained by subtracting the second current from the sum of the first and third currents.

Abstract: A mounting device of the described type may be viewed as being somewhat similar to a camera tripod, for example. Four extendible legs are adapted to be secured to the arms of a wheelchair. Two of the legs terminate in flat pad mounts which may be attached to and rest upon the upper broad and flat surfaces of wheelchair arms. The other two legs include interchangeable ends, some of which may also include flat pad mounts to be attached to the flat surfaces of such arms, and others of which may include spring-clips that may be snapped over or clamped around a bar with a circular cross section. The flat pads are preferably held in place by straps using "Velcro" hook and loop fasteners. The spring-clips are primarily devices which may be pushed into place around a circumference of a circular pipe. Optionally, a wing nut may supplement the circular clamps to more securely hold them in place.

Abstract: A plastic material which is suitable for simulating engraving on metal has a substrate which is not deformed by the heat or pressure of a hot stamping process. A sheet or layer of thermoplastic material of limited thickness is laminated to the upper surface of the substrate. The opposite side of the thermoplastic material is covered by a containment film. Thus, within the limits of manufacturing tolerances, the layer of thermoplastic material may be subjected to any amount of pressure to produce a debossment which is no deeper than the depth of the limited thickness when a hot stamping die bottoms on the non-deformable substrate. Therefore, there is a much more predictable end product.

Abstract: An integrated waste reclamation and processing system converts biodegradable liquid and solid waste into poultry products (or the like) and humus-like substances. The system uses earthworms and poultry in a manner in which biodegradable waste is first composted and then used as a substrate for newly hatched worms. The worms grow in the waste for about eighty days and then are harvested and fed to chickens or laying hens, in combination with other food. The waste left behind by the worms has humus-like properties which can be used as a soil conditioner on eroded, strip-mined, or desert land. This conversion system, which is preferably contained in a closed building and maintained operational throughout the year, it is applicable to the needs of small and large waste-producing institutions and facilitates the reclamation of biodegradable waste in a manner which is environmentally acceptable and economically feasible. The structures and machinery used in the system are also shown and described.

Abstract: An electrolytic process generates erasable pictures on a solid electrolyte substrate to electrically record data without consumption of energy. The substrate is electrically erasable at will, and then is capable to record data again, and usable as well in telecopy receiver apparatus as display screen. The recording may be made by using an unwearable electrode made of a metal and using a low voltage power supply, for instance under 10V, and a small current. The substrate is substantially unsensitive to ambient light. An electrolytic process locally generates an optical absorption at the surface of an electric conductive layer connected to an anode. The layer has an optically diffusing powder and a metal compound, the amount of which is relatively small. The optical absorption is produced at the contact point between a supplied cathode and the surface by means of a reduction of the metal compound.

Abstract: A read only-memory (ROM) is manufactured by a process which produces memories having customized codes from partially completed semiconductor chips. The chips are manufactured to a step where a matrix of apertures or windows are formed in an oxide layer at every cross point of every potential code. Then, a silicon dioxide film is formed over the entire surface of the chip including the window apertures. At this stage, the chip is stored as a general purpose stock item. When an order is received to prepare a ROM chip with customized codes, a mask is formed to etch and reopen the apertures or windows in the dioxide film at the encoded cross points. Then, suitable contact material is deposited over the surface of the chip, thereby completing a contact at each of the reopened apertures or windows. As a result, the normal lead time required for a manufacturer to make a customized ROM is reduced from, say, 4.5 to 6 days to a period of approximately 1.5 to 2 days.

Abstract: A water meter eliminates the usual conversion gear trains by using a permanent magnet which rotates in proportion to the volume of water to be measured. A magnetic field sensor, comprising a ferromagnetic magnetoresistor, produces a sensor signal which varies as a function of the rotation of the magnet. A wave shaper forms the sensor signal into a sequence of pulses which drive a totalizer for producing a signal indicative of the volume of the water used. The output of the totalizer is supplied to an indicator device which displays the total amount of water passing through the meter, in terms of a predetermined unit of measure. Preferably, the sensor comprises at least two magnetoresistors for producing two sensor signals with a phase difference therebetween. The wave shaper then produces two pulse sequences for identifying a normal and an inverse flow of water, respectively. These two sequences cause the totalizer to count up or down, respectively.

Abstract: The invention provides an easily transportable, general purpose box which may be carried about by hand and then anchored to rails and locked in place. Once the lid is locked on the box, no one without a key can move the box from the anchor rails. The invention is primarily intended as a portable trunk for mounting on a truck; however, it may be used anytime that a box is to be mounted on a chassis, such as a toolbox mounted on a wheeled dolly, a toolroom shelf, or the like, for example.

Abstract: Meters accumulate peg count signals occurring in an observed telephone system. These signals are subtotaled on a daily basis, and totaled on a weekly or similar basis, for the seven-day period (for example) immediately following an initial start or reset. The outputs of these meters are connected to a pollable device which may be seized via the telephone switching system being observed, whenever central testing or similar equipment dials the directory number of such a pollable device. This way, the peg count information may be automatically processed by a central computer, without necessarily requiring the intervention of a human operator.
