Abstract: A cathode for a lithium secondary battery includes a cathode current collector, and a cathode active material layer formed on the cathode current collector. The cathode active material layer includes a cathode active material and a conductive material ID/IG is in a range from 0.5 to 1.25 in a Raman spectrum of the cathode active material layer. The cathode active material includes lithium metal oxide particles containing nickel and manganese and having a content of cobalt of less than 2 mol % among all elements except for lithium and oxygen.

Abstract: A method for manufacturing a flavor capsule of tobacco according to an embodiment of the present disclosure may comprise: a membrane manufacturing step for manufacturing a membrane of a flavor capsule by a membrane manufacturing part that manufactures a membrane; a capsule manufacturing step for manufacturing the flavor capsule using an apparatus for manufacturing a capsule with the membrane manufactured during the membrane manufacturing step and a flavored liquid to be held in the membrane; and a hardening step for hardening the flavor capsule.

Abstract: Disclosed are a separator for fuel cells capable of minimizing the volume of a system and the use of sealants, and a stack for fuel cells, more particularly, a stack for solid oxide fuel cells, including the same. Specifically, by adding a metal sheet having a specific shape, position and size to the separator, the stress applied to the sealant can be uniformized, and thus the oxidizing agent and fuel can be separated and electrically isolated using only a piece of sealant. Therefore, the stack for fuel cells is characterized in that there is no variation in temperature, reactant concentration, power, or the like between respective unit cells, so delamination and microcracks do not occur, the volume is minimized, and the power density per unit volume is very high.

Abstract: An embodiment device includes an input module including a motor configured to generate a rotational force, an output module configured to receive power from the input module to be rotatable, and a connection module having a first side coupled to the input module and a second side, opposite the first side, coupled to the output module, wherein the connection module is configured to transmit the power from the input module to the output module.

Abstract: Discussed is a protection circuit module that may include a printed circuit board configured to be connected to a positive lead part and a negative lead part connected to a battery cell, wherein the printed circuit board includes an upper layer bonded to the positive lead part and the negative lead part so as to be electrically connected; an intermediate layer including a first insulating layer including a material containing an epoxy resin and provided below the upper layer; and a laser reflective layer provided between the upper layer and the first insulating layer and reflecting light from a laser.

Abstract: The present inventive concept relates to a system for operating a region-originating development platform, comprising: a service server for coordinating a regional service between a physical card and a mobile terminal of a user, one or more regional member stores, and a regional integration server; and an operation management portal running on the service server, comprising a system portal part used to operate a system within the service server, a platform portal part for managing one or more merchandises offered as the regional service, and a partner portal part for managing partners including member stores, where the regional integration server comprises sub-institution servers in a layered structure to operate in conjunction with one or more base center servers at a lower level, and the mobile terminal runs a service application for providing the regional service and comprises information of at least one mobile card issued upon a request.

Abstract: A cell bus arbitration device and method arbitrating a cell bus transmitting data in a certain size of packet unit is disclosed. The cell bus arbitration device comprises a filter for outputting request signals not to be masked by using service mask data, a decoder for outputting only the highest priority request signal, a latching and counting unit latching and counting the priority signal, a service flag for outputting service mask data according to the bus grant signals, and a detector for detecting the state of the bus request signals and controlling the service flag unit. The device is used for arbitrating a cell bus for transmitting data in packet unit.

Abstract: A self-control type bus arbitration circuit and an arbitration method are disclosed, in which a bus arbiter is not needed, but entities commonly connected to a bus share 3 kinds of information, so that the entities can arbitrate the bus ownership use for themselves, and can occupy the bus in accordance with the priorities without mutual conflicts. Further, in order to solve the problem of the limit in the number of the sharing entities, the entities are made to use a clock information contained in the 3 kinds of information, i.e., the clock, the reference pulse and the in-use signal information, in such a manner that the clock is multiplied by an integer within the entities.
