Abstract: A benefit awarding system includes a terminal device and a server device. The terminal device includes: a first acquiring unit that acquires a product identifier for identifying a product; and a first transmitting unit that transmits a user identifier indicating a user and the product identifier acquired by the first acquiring unit, in a case where this terminal device is positioned inside a shop. The server device includes: a first receiving unit that receives the user identifier and the product identifier transmitted by the terminal device; and an update unit that updates benefit information stored in a storage unit in association with the user identifier received by the first receiving unit, with information indicating benefits corresponding to the product identifier received by the first receiving unit.

Abstract: The object of the invention is to provide pharmaceutical composition that can be used as a therapeutic and/or prophylactic agent. Particularly, the pharmaceutical composition of the invention has significant therapeutic effect and survival benefit for the disease caused by parasitic protozoa, and selective toxicity against the causative protozoa. The pharmaceutical composition comprises a compound represented by general formula (1). Particularly, the invention relates to a composition that is an effective therapeutic/prophylactic agent for malaria, leishmania, African sleeping sickness, Chagas disease, toxoplasmosis lymphatic filariasis, babesiosis, and coccidiosis, and a novel compound contained therein.

Abstract: The purpose of the present invention is therefore to provide a pharmaceutical composition, especially that for the treatment and/or prevention of parasitic infection by protozoa, which has a high therapeutic effect and selective toxicity or a life-prolongation effect for the parasitic infection by protozoa.

Abstract: A circuit breaker with a high linearity is provided which detects a current in a main circuit in a low current region by means of a current transformer, while the current in a high current region is detected by a current detector using a Hall element.

Abstract: An electric circuit breaker including a current sensor composed of a Hall generator for detecting current overloads. Two secondary windings of a current transformer associated with the power line are connected to provide power to two separate power supply circuits. One circuit supplies power to a control circuit and the other circuit supplies control current to the Hall generator. The output voltage of the Hall generator is compared with a predetermined value in the control circuit. If a predetermined overload occurs, the control circuit energizes a trip coil for opening the power line.
