Abstract: A device and method for identifying a bank note with simple construction offering easy adjustment and a reliable performance independent of environment under which it works enables to identify a bank note printed in color with a genuine one by adjusting intensity of light emission so as to equalize sensitivity of a photoelectric transducer to a light source A and a light source B, emitting lights in different wavelengths, when there is no object to be identified, detecting difference in sensitivity of detected signals of light transmitted through or reflected by the object to be identified as output of a high-pass filter, sampling, in a sampling circuit, signal based on the sensitivity difference and proportional. to the difference between detected value for light source A and sensitivity of light source B to conduct identification based on the sampling value.

Granted: 2002-01-22
Abstract: A hydraulic apparatus is used in an industrial vehicle.  The apparatus  has a hydraulic cylinder interposed between a vehicle frame and an axle swingably coupled to the frame.  A passage connects a first chamber with a second chamber defined by a piston in a cylinder case.  The piston is movable based on differential pressure in the chambers. A cylinder rod selectively extends and retracts in respect with the cylinder case to absorb a swinging motion of the axle.  The passage is selectively open and closed based on at least one of a traveling state and a loading state of the vehicle.  The piston has a first surface defining the first chamber and a second surface defining the second chamber. The first surface has an area equal to that of the second surface.

Abstract: The invention concerns a method and device for the rapid, simultaneous isolation of genomic desoxyribonucleic acid (DNA) and cellular total ribonucleic acid (RNA), free of genomic DNA from various starting materials. The fields of application are molecular biology, biochemistry, gene technology (in particular gene therapy), medicine, biomedical diagnosis, veterinary medicine, food analysis and all related fields. The method proposed is characterized in that materials containing DNA and RNA are lysed in a special buffer, the lysate incubated with a mineral carrier, the carrier with the DNA bound to it separated off and washed with buffer solution, and the DNA subsequently separated from the carrier with a buffer of lower salt concentration. The lysate left after separating off the DNA bound to the carrier is mixed with phenol, chloroform and sodium acetate in defined proportions, the phases allowed to separate, and the total RNA precipitated from the aqueous phase by adding isopropanol. Lysis is carried out using buffers containing chaotropic salts with a high ionic strength. Lysis of the material and bonding of the genomic DNA to the carrier are both carried out in the same buffer. Both the lysis of the starting material and all necessary washing steps are carried out in an apparatuswhich makes it possible to process 12 samples in parallel.

Abstract: Adjacent first and second transistors are integrated with a substrate. Each of the first and second transistors has a gate electrode, a source electrode, a dra in electrode and a semiconductive channel formed of an organic material, the semiconductive channel electrically coupling the source electrode with the drain electrode. The source electrode of the first transistor is electrically coupled to the source electrode of t he second transistor. A molecular receptor is bound directly to a surface of the semiconductive channel of the first transistor. A non-zero offset voltage, which produces equal channel currents in the semiconductive channels of the first and second transistors after a molecule has bound with the molecular receptor without a like binding event proximate to the second transistor, is sensed between the gate electrodes of the first  and second transistors.

Abstract: A control terminal 32 includes an individual address setting section 12 for setting a unique individual address, and a simultaneous control address setting section 13 for setting a simultaneous control address common to the plurality of control terminals 32. A simultaneous control address is commonly assigned to the control terminals 32 to be subjected to group control. When an UP switch Sb or a DOWN switch Sc of an operation terminal 31b for group dimming purpose is pushed, a transfer signal including the simultaneous control address is transmitted to a signal line Ls from a transfer controller 30. The respective control terminals 32 substantially simultaneously receive the transfer signal, thereby changing the intensity of illumination loads.

Abstract: A dressing (110) for promoting healing and pain relief of the body of a livi ng organism having a pathologic condition has at least one layer of conductive material (114) having a resistance no greater than 1000 .OMEGA./cm2. When placed proximate a portion of the body of the living organism suffering from the pathologic condition (5), the dressing alters the electrodynamic processes occurring in conjunction with said pathologic condition to promote healing and pain relief in the living organism. When used as a wound dressing, the conductive material (114) is placed in contact with tissue (21) around the periphery of the woun d and with the wound (19), lowering the electrical potential (23) and resistance (27) of the wound (19) and increasing the wound current. In an exemplary embodiment, the conductive material (114) is a multi-ply nylon fabric (194) plated with silver by an autocatalytic electroless plating process and with the plies in electrical continuity. The dressing provides an antimicrobial and analgesic effect.
