摘要:
Screens are positioned at front areas of respective placing tables which form placing spaces for placing an article. Each of the screens is a transmission-type screen capable of transmitting projection image light projected on a back side of the screen. A first optical system and a second optical system are arranged inside the display shelf. The first optical system leads first partial image light, which is included in projection image light projected from a projector in the display shelf, to the back sides of the screens. And the second optical system leads second partial image light, which is included in the projection image light, to at least one of the placing spaces.
摘要:
The object of the present invention is to provide a non-aqueous electrolyte secondary cell that excels in safety against overcharging and shows only a small increase in thickness during continuous charge. This object can be achieved by adopting the following configuration: a separator is used that is made of a microporous polyolefin membrane having an average pore diameter of 0.07 to 0.09 μm; a non-aqueous electrolyte contains 0.5 to 3.0 mass % of 1,3-dioxane, 0.05 to 0.3 mass % of adiponitrile, and 0.5 to 3.0 mass % of cyclohexylbenzene and/or tert-amylbenzene relative to the mass of the non-aqueous electrolyte; and preferably the non-aqueous electrolyte further contains 0.5 to 5.0 mass % of a vinylene carbonate and 0.1 to 2.0 mass % of 2-propyn-1-yl 2-(methylsulfonyloxy) propionate.

A display shelf system includes a display shelf, which includes a plurality of placing tables which are adapted to have an article placed thereon. A plurality of transmission-type screens are arranged with the placing tables, respectively. A projector projects a projector image, and a light guide of the display shelf leads the projector image onto the rear sides of the transmission-type screens. The transmission-type screens have curved surfaces which are inclined to face toward a lateral direction with respect to a front of the display shelf, so that the transmission-type screens are easily viewable by viewers who are in the lateral directions of the display shelf.

An ESL server (3) includes a management-device storage unit for storing information indicating a position at which a second electronic shelf label terminal (1) is installed, a management-device reception unit for receiving information transmitted from a transmission unit of a handy terminal (5), and a management-device control unit for identifying a position at which a first electronic shelf label terminal (1) is installed based on information for uniquely identifying the first electronic shelf label terminal (1), information for uniquely identifying the second electronic shelf label terminal (1), information indicating relative position between the position at which the second electronic shelf label terminal (1) is installed and the position at which the first electronic shelf label terminal (1) is installed, and the information indicating the position at which the second electronic shelf label terminal (1) is installed.
摘要:
An image display controller for a display shelf generates image data for a projector image which is projected by a projector arranged in the display shelf to be displayed on a transmission-type screen of the display shelf. The image display controller includes a monitor, an input device, a data communicator, a memory, and a controller. The controller obtains an editing background image from the memory and displays the editing background image on the monitor, and generates contents of a display image. Moreover, the controller sets a position of the generated display image in a desired position of a display area of the editing background image in response to an instruction inputted via the input device, and generates the projector image by combining the generated display image into the editing background image at the set position.
摘要:
A highly pure borate complex of a trialkylborane with an alkylated or arylated alkali metal is obtained by reacting an aryl magnesium halide with a boron trihalide to produce a triarylborane product. The triarylborane product is then subjected to thorough removal of magnesium salts produced as by-products and removal of unreacted aryl magnesium halide. A solution of alkylated or arylated alkali metal in a hydrocarbon solvent, a straight chain ether solvent or a mixed solvent thereof is then added dropwise to the solution of triarylborane product in a hydrocarbon solvent, straight chain ether solvent or mixed solvent thereof, while keeping the temperature range from -80.degree. to 25.degree. C.
