Patent CA-1043420-A (CA)
Inventor: DOBKIN ROBERT C
IPC: H03F3/34
Filed: 1975-08-06
Granted: 1978-11-28
Abstract: Application for Patent of Robert C. Dobkin for INPUT SUPPLY INDEPENDENT CIRCUIT         ABSTRACT OF THE DISCLOSURE      A circuit includes a plurality of transistors which are biased by a supply to provide an output which is independent of that supply and dependent only on the summation of the base-emitter voltages of the transistors, if any.  A first pair of transistors are connected in series with one another between the supply and a second pair of transistors are connected in series with one another between the supply.  The base-emitter junctions of the transistors are connected in a series loop, such that a voltage is developed between the base-emitter junc-tions of two adjacent transistors which is equal to the base-emitter voltage summation.  The base-emitter voltages of any series connected transistors oppose one another in the series loop.  Since the collector currents of the series connected transistors are equal to one another and their base-emitter voltages oppose one another in the series loop, the base-emitter voltage summation will be independent of collector currents and, therefore, independent of the input supply.  The circuit can be employed as either a voltage or current regulator.  As a regu-lator circuit, the emitter area of one transistor is different than the emitter area of another transistor, such that the sum-mation of the base-emitter voltages will be other than zero and independent of the input supply.  The circuit can also be em-ployed as a buffer amplifier by making the emitter areas of the transistors equal to one another.

Abstract: TITLE         PNEUMATIC TIRE BUILDING SYSTEM AND APPARATUS FOR USE THEREIN     ABSTRACT OF THE DISCLOSURE     A method and apparatus for making a pneumatic tire and particularly a giant off-the-highway radial type pneumatic tire is provided preferably by first forming a tire carcass around a tire carcass building drum and transporting the tire carcass to a second stage tire building machine by a carcass transport support means.  The second stage machine comprises a first rotatable detachable building drum on a first shaft preferably capable of vertical positioning for placing the tire carcass on the first drum.  The first drum is adapted to expand the tire carcass to a substantially toric configuration.  A second rotatable collapsible drum for building a breaker assembly is mounted on a second shaft coaxially of the first shaft.  Breaker transfer means travels over and between the drums to transfer the breaker assembly from the second drum to the first drum.          When the breaker assembly is positioned over the first drum, the carcass is expanded into a toric configuration and mates with the breaker assembly.  The combined breaker assembly and carcass is then stitched, the tread portion applied, and the detachable building drum with the assembled tire thereon is placed in a curing means such as a mold or pot heater.

Abstract: ABSTRACT OF THE DISCLOSURE Methods of making semiconductor devices using the technique of impact sound stressing are disclosed. Impact sound stressing (ISS) is a mechanical acoustical technique to damage, in a known and controlled manner. semi-conductor wafers. Wafers are subjected to ISS on the backsides before semi-conductor processing steps. The application of ISS before the first high temperature application with control the generation and subsequent direction of flow (gradient) of vacancies (interstitials) generated through all device high temperature processing steps including ion implantation. ISS redirects the flow of vacancies/interstitials into the backside away from the device area of the wafer. Thus, the device area is swept clean in a gettering action of vacancy/interstitials and their complexes which are detrimental to device performance. The techniques of impact sound stressing finds application in improvement the performance of all semiconductor devices, specifically dynamic memories, bipolars, solar cells and power devices.

Abstract: --START-UP CONTROL FOR FUEL INJECTION SYSTEM--ABSTRACT OF THE DISCLOSURE            A fuel injection system for a multi-cylinder engine includes means for generating a sequence of pulses during each cycle of the engine.  These pulses trigger variable width pulse generators, sensitive to the engine operating parameters.  The variable width pulses are pro-vided to the injectors so that each ejector fires once during an engine cycle and their firing times are spaced over the cycle.  During start-up, the pulse widths are diminished and all of the injectors are fired each time the sequencing circuitry provides an output pulse.  The total charge provided to each cylinder is thus distributed over the engine cycle, insuring the presence of the proper quantity of fuel for optimum flammability to achieve start-up of the engine in at least one of the cylinders.

Improved mounting appa-ratus is provided for supporting both the forward and back end portions of the dispensing coil.  A cross-bracket member having a portion extending across the diameter of the coil, is mounted to the back portion of the coil.  A cross-bracket holding device, connected for rotation by appropriate motor means, releasably accepts the cross-bracket for mounting the back portion of the coil in elevated position above the shelf surface of the dispensing tray.  The cross-bracket holding device is configured to matingly accept differently sized cross-bracket members, to enable rapid interchangeability of differently sized dispensing coils in the machine.  Coil sup-port apparatus mounted to slidably engage the outer circum-ference of the dispensing coil near its forward end supports the forward end of the coil in elevated spaced-apart manner above the tray surface, and supports the coil in a manner which minimizes jamming of the items being dispensed at the forward end of the coil.  Coil compression means mounted adjacent the forward end of the dispensing coil causes the coil to positively eject or to impart dispensing motion to the item being dispensed from the convolutions of the coil, during the dispensing rotation movement of the coil.

Abstract: PRECIS DE LA DIVULGATION       Dans la fabrication des fleurs artificielles en bois on utilise actuellement des moules où on insère manuellement des pé-tales découpés dans une mince feuille de bois et humectés préala-blement.  Les moules sont ensuite placés dans un four pour le sé-chage des pétales, leur conférant une déformation permanente.       Dans la présente invention on utilise une machine qui comprend un bâti supportant un convoyeur, dote d'une bande de texture spongieuse et d'épaisseur suffisante pour obtenir une dé-formation adéquate des pétales.  Un dispositif chauffant est placé au-dessus de la partie supérieure du convoyeur, dispositif qui peut pivoter autour d'une articulation pour modifier la pression exercée par un rouleau chauffant dudit dispositif.  Le rouleau chauffant qui est en rotation contient un élément chauffant fixe à température contrôlée.  Pour assurer le pressage nécessaire du rouleau chauffant sur la bande du convoyeur, on utilise un dispo-sitif de serrage, agissant par l'intermédiaire de tiges filetées et d'écrous sur le dispositif chauffant.  Dans le but d'assurer une alimentation continue qui permet une utilisation complète de la capacité de la machine, celle-ci est pourvue de magasins où sont empilés les pétales et d'un convoyeur d'alimentation, au-dessus duquel est placé un rouleau en rotation.  Ce rouleau a une vitesse et une position telles, qu'il réalise la séparation efficace des pétales sortant des magasins.  Des rouleaux superpo-sés ayant une vitesse adéquate et disposés entre les deux convoyeurs entraînent entre eux les pétales qui quittent le convoyeur d'ali-mentation, les dirigeant entre le premier convoyeur et le rouleau chauffant.
