The existing earphone jack provided on portable information terminals can be adopted as the plug for the digital camera or insertion plug for the connector of USB cable, so that the cost can be lowered and the system made compact to provide a highly flexible portable information terminal and a digital camera for use with the portable information terminal.

Abstract: An elevator system in which a car travels upward and downward among a plurality of floors. The elevator system includes terminals each having a wireless transmitting/receiving unit. One of the terminals is correspondingly provided for at least one of the plurality of floors and another of the terminals is correspondingly provided for the car and at least one of a counterweight. A mobile terminal is provided which enables wireless transmitting/receiving of signals between the terminals which are arranged within a predetermined distance of each other.

Abstract: A water pump bearing with a seal structure on an impeller side including a ring-shaped first seal unit having its outer circumferential portion fixed to an inner circumferential portion of an outer ring and its inner circumferential portion in sliding-contact with an outer circumferential surface of a pump shaft, and a ring-shaped second seal unit disposed axially outward from the first seal unit with its inner circumferential portion fixed to an outer circumferential portion of the pump shaft and its outer circumferential portion in sliding-contact with the outer ring.

Abstract: An elevator system in which a car travels upward and downward among a plurality of floors includes an elevator control unit and terminals each having a wireless transmitting/receiving unit. The terminals are provided for the elevator control unit and for each of the floors. Transmitting/receiving of signals between two of the terminals distant from each other is effected so as to at least enable wireless bi-directional communication between the two of the terminals distant from each other by relaying signals through another wireless transmitting/receiving unit of another of the terminals.

Abstract: In order to make it possible to transmit and receive information between terminals and to reduce the number of wires used for an elevator in a building in an elevator system by transmitting and receiving information through wireless transmission even if a very weak radio wave having a narrow communicable range is used, an elevator control unit, a car terminal and floor terminals are individually provided with short distance wireless transmitting/receiving units having a communicable range of nearly a 2-floor distance (5 to 6 m) using very weak radio waves. The radio waves are received and transmitted between the wireless transmitting/receiving units located within the communicable range to transmit information by a relaying method of sequentially transferring information from terminal to terminal until it reaches a final destination.

Abstract: A method of detecting nucleic acid fragments in plural samples is performed by the steps of: attaching an electroconductive label to nucleic acid fragments in one sample and attaching a different electroconductive label to nucleic acid fragments in another sample; preparing a mixture of these samples; spotting the mixture on an electroconductive microarray having plural electrodes onto which probe molecules complementary to the nucleic acid fragments are fixed, so that hybridization between the nucleic acid fragments and the probe molecules on the electroconductive microarray can proceed to form hybrid structures; applying to the electrode an electric potential corresponding to the oxidation-reduction potential of the former label and detecting on the electrode an electric current; applying to the electrode an electric potential corresponding to the oxidation-reduction potential of the latter label and detecting on the electrode an electric current; and comparing the electric current detected in the former de

Abstract: A method of analyzing a nucleic acid fragment sample to judge whether the nucleic acid fragment sample is uncomplementary, partly complementary or complementary to a DNA fragment in its specific base sequence is conducted by the steps of: bringing an aqueous solution of the nucleic acid fragment sample into contact with a DNA chip having an electroconductive substrate and the DNA fragment fixed onto the substrate in the presence of an electrochemical thread intercalator; measuring an electric current flowing from or to the electroconductive substrate along the DNA fragment under application of a potential to the substrate; and comparing the electric current measured above with a referential electric current which is prepared employing a DNA chip equivalent to the above DNA chip, the intercalator, and an aqueous solution of a nucleic acid fragment which is complementary to the DNA fragment of the DNA chip.

Abstract: A compound of the following formula: Ea—La—X—Lb—Eb in which each of Ea and Eb independently is a group having oxidation-reduction activity and having a conjugated system in its group; X is a divalent cyclic group; and each of La and Lb independently is a group which does not form a conjugated system in combination with the conjugated system of each of Ea and Eb and at least one of which has a site imparting water solubility to the compound or a site that is convertible into a site imparting water solubility to the compound, is favorably employable as an electroconductive threading intercalator in an electrochemical method for detecting complementary DNA fragments.

Abstract: A tongue lid pack includes a body containing a packing article of filter cigarettes, and a cutting line is formed on the front wall of the body. A tongue lid is hingedly connected to the opening end of the body, and the tongue lid has a lid portion for closing and opening the opening end and a tongue extending from the lid portion and a bent tip. When the tongue lid is closed, the bent tip of the tongue is inserted through the cutting line of the front wall. Also, a blank for the tongue lid pack and a method for folding the blank are disclosed.

Abstract: An assortment of objects is dispensed from a plurality of object holders onto a conveyor for loading into a container at an end of the conveyor. The objects are dispensed onto discrete sections of the conveyor with like objects occupying like sections. Since like objects are grouped together on the conveyor, damage due to any impact between objects is reduced because, when objects impact objects of the same class, less damage occurs than when disparate objects impact each other. Discrete sections with heavier objects are located upstream of discrete sections with lighter objects. When the lighter and heavier objects are discharged from the conveyor into the container, the lighter objects are loaded on top of the heavier objects, thereby reducing any damage which occurs through impact. Gaps on the conveyor between different groups of objects reduces the likelihood of impacts on the conveyor.

Abstract: An object discharge mechanism for discharging a bottommost object from a stack of objects includes a bottom platform on which the bottommost object of the stack of objects rests. The platform has a longitudinal slot running along the object discharge direction. The upper portion of a belt, stretched between two vertically mounted pulleys, runs through the longitudinal slot parallel to the upper surface of the bottom platform. Discharge projections are mounted periodically on an outer surface of the belt. The discharge projections push objects across the bottom platform in the object discharge direction when the belt is rotated. The object discharge mechanism also includes a lifting member for lifting all objects above the bottommost object in the stack of objects. The lifting member reduces the frictional force created by the weight of the stack of objects on the bottommost object during discharge of the bottommost object.
