Patent EP-0344930-A1 (EP)
Inventor: NITTA KOJI C O OKI ELECTRIC IN
IPC: G03G21/00
Filed: 1989-05-09
Abstract: A printer has a photoconductor (103), a charger (111) an exposure unit (115) a container (125) containing toner particles (119) and carrier particles (121), a developing unit (117) that feeds the toner particles onto the photoconductor surface, a bias generator (140) and a bias generator controller (150). The charger (111) induces an electric charge on the charged area of the photoconductor surface so as to establish a first electric potential (Vs) on the photoconductor surface (103a) which retains the electric charge for significant period of time. The exposure unit (115) forms a latent image within the charged area. The bias generator (140) provides the developing unit with a second electrid potential (Vdb) so as to produce a potential difference (Vdb - Vs) between the developing unit (17) and photoconductor surface. Thereby the toner particles are significantly attracted to the latent image on the photoconductor surface. The   developing unit (117) thereby applies the toner particles from the container to the photoconductor surface. If the charger stops inducing the potential (Vs) due to a malfunction of the printer, the bias generator controller (150) causes the bias generator (140) to provide the developing unit (117) with the same electric potential (Vdb) for a predetermined period of time, until either the carrier particles are not significantly attracted to the electric charge or the charged area of the photoconductor passes away from the position adjacent to the developing unit (117) after the charger stops inducing the potential (Vs). When the printer is actuated by a switch (109), the bias generator controller further causes the bias generator (140) to provide the developing unit (117) with the second electric potential (Vdb) prior to the charged area being transported into the position adjacent to said developing unit in response to operation of the switch to actuate the printer.

Abstract: A syrup dispensing system in which a pump (20-26) is actuated at a preset clock rate under a fixed pressure head. The clock rate and pressure head are tailored to accommodate the lowest operating temperature for the system and, accordingly, the thickest syrup. The system will allow a preset amount of syrup to be dispensed one each clock cycle such that a uniform and guaranteed rate of syrup flow can be attained.

Abstract: Dispensing apparatus (1) for dispensing a liquid product (24) from a pressurised dispensing container (21) comprises a collapsible chamber metering valve (2) in which an elastomeric sleeve (4) overlays an external surface (53) of the valve body (6) to define a metering chamber (7) therebetween and is collapsible on actuation of the valve into substantially conformal contact with the external surface such that a volume of liquid is dispensed which is equal to the volume of liquid displaced from the metering chamber. The valve is nestably received within a cup (3) with seal means (15) operable between the mouth of the cup and an outer end of the valve such that a closed collecting chamber (11) is defined between the valve and the cup. Means (25) are provided to communicate in use between the collecting chamber and that part of the container in which a liquid product is contained when the container is held in a predetermined orientation for operation of the valve.

Abstract: A miniaturized ultrasonic probe comprises a housing (102) encasing a motor (101), an ultrasonic transducer (104) mounted for controlled rotation on the motor shaft (103), and an angular position sensor (105) connected to the shaft. The housing has a radiating dome (106) about the transducer and is sealed and wholly filled with an acoustically-transparent fluid. The dual frequency transducer operatively emits either of two ultrasonic frequency beams from opposed faces (108, 109) of a sandwich-like construction, and the position sensor is implemented using a low mass variable-inductor arrangement. The resulting probe attains unusually rapid accelerations and changes in beam direction with highly accurate control of transducer orientation, all in a miniaturized construction particularly well adapted for operative insertion in a human or animal body cavity or surgical site.

Abstract: A circuit arrangement includes a lamp filament (1) as a load and a resistor (2) in series with the filament. For detecting the current through the load, the source of a MOSFET (6) is connected with the end of the resistor remote from the filament, the drain of the MOSFET being connected with the other end of the resistor via the primary winding of a step-up transformer (7) and a further resistor (8), a diode (9) being connected between the source and the drain of the MOSFET. If the MOSFET is turned on by an appropriate voltage at an input (11) connected to its gate, the voltage across the secondary winding of the transformer is substantially proportional to the value of the current through the filament.

Abstract: Le procédé décrit, qui sert à administrer des agents thérapeutiques à travers la barrière sanguine du cerveau, utilise une technique de neutralisation des médicaments, ainsi que la perméabilité sélective de la barrière sanguine du cerveau. Pendant et après la formation de lésions cérébrales, la barrière sanguine du cerveau devient de plus en plus perméable. Pour traiter ces états, on administre une quantité thérapeutiquement efficace d'un médicament choisi, qui présente un poids moléculaire et d'autres caractéristiques permettant le passage du médicament à travers la barrière sanguine du cerveau modifiée. Une substance neutralisante spécifique aux médicaments est ensuite administrée. La substance neutralisante présente un poids moléculaire élevé et/ou quelque(s) autre(s) caractéristique(s) qui empêchent son passage à travers la barrière sanguine du cerveau modifiée. La substance neutralisante se lie ou réagit avec l'excédent de médicament circulant à l'extérieur de la barrière sanguine du cerveau, afin d'empêcher l'apparition de problèmes de toxicité du médicament.
