Abstract: According to one embodiment, a light-emitting device includes a light source section including a plurality of series circuits, in each of which a plurality of light-emitting elements are connected in series, the plurality of series circuits being connected in parallel, and a substrate on which the light-emitting elements of the light source section are mounted. The light-emitting elements of the series circuits different from one another are mounted adjacent to one another.

Abstract: A communication system is configured to include at least one information-processing device, at least one information-providing server and a management server. The management server manages whether contents to be transmitted to the information-processing device, which has been registered with the information-providing server, are available in the information-providing server. The information-processing device requests the management server to check availability of specified contents at intervals of a transmission period predetermined for each of the specified contents and receives a check result therefrom.

Abstract: The refrigerated or heated air flow within the storage chamber of a vending machine is varied by an air flow control device. A baffle plate or cover plate, or combination thereof, is used to control the direction of air flow. The position of these plates in turn is controlled by spring elements. One of the spring elements is formed of shaped memory alloy so that its recoil strength changes in accordance with its surrounding temperature. Thus, the difference in recoil strength between these spring elements changes with temperature. That difference is used to position the baffle and/or cover plates to control air circulation.

Abstract: A temperature control device is disclosed for use in a vending machine having a plurality of storage chambers. The temperature control device includes a refrigerating apparatus provided with a plurality of evaporators which are connected in parallel and disposed individually in the storage chambers. A plurality of electromagnetic valves are coupled in series with the evaporators to control the inflow of refrigerant fluid. The operation of each electromagnetic valve, i.e., the temperature control in each storage chamber is controlled by a comparison of the average temperature of the storage chambers with the actual temperature in each chamber. The operation of the refrigerating apparatus and the electromagnetic valves are also controlled by a comparison between the desired temperature and the actual temperature in each chamber.

Abstract: There is disclosed a refrigerating apparatus suitable for use in a vending machine having a plurality of storage chambers. The refrigerating apparatus is provided with a plurality of evaporators which are connected in series and disposed individually in the storage chambers for refrigerating the same. A plurality of expansion devices are coupled in series with the evaporators, each of the expansion devices and evaporators being provided with a bypass having a valve means to direct the flow of the refrigerant into the evaporator through at least one of the expansion devices.

Abstract: A refrigerating unit suitable for use in a vending machine which is provided with a plurality of isolated chambers for storing the different types of merchandise comprises a condensing unit which includes compressor and condenser, with two parallel connected evaporators each evaporator being disposed in one isolated chamber of the vending machine and connected with the condensing unit through a suction and a discharge lines, and a capillary tube is inserted on suction side of each evaporator. Therefore, two refrigerant circuits are provided. A part of each suction line of one refrigerant circuit is closely disposed to extend along the capillary tube of the other refrigerant circuit. Thereby operation of one refrigerant circuit is directly controlled by the operating conditions of other refrigerant circuit.

Abstract: The present application discloses a first-order balancer of an internal combustion engine comprising forward-rotating fly-wheels fitted on both ends of a shaft and allowed to rotate in the same direction as said shaft, backward-rotating fly-wheels fitted respectively on said both forward-rotating fly-wheels and allowed to rotate in the opposite direction from said both forward-rotating fly-wheels, forward-rotational counterweights placed on said both forward-rotating fly-wheels, and backward-rotational counterweights placed on said both backward-rotating fly-wheels and having a different weight from said both forward-rotational counterweights. According to the first-order balancer of an internal combustion engine of the present invention, vertical and horizontal first-order unbalanced moments arising in an internal combustion engine may be simultaneously balanced.
