Abstract: There are provided a compact and portable refrigerant recovery device which can easily recover a refrigerant present in a refrigeration circuit of a used-up household refrigerator or an extra-low temperature freezer which uses a low boiling point refrigerant at low costs, and a method for recovering a refrigerant by using the refrigerant recovery device. In the refrigerant recovery device comprising a refrigerant recovery tank which stores an activated carbon for adsorbing the refrigerant, the recovery tank is equipped with a detachable cap, and the activated carbon is wrapped in unwoven cloth finer than a grain diameter of the activated carbon, and stored in the recovery tank. The refrigerant recovery device is connected to the refrigeration circuit, a gas in the refrigerant recovery tank is vacuumed to be discharged before the refrigerant of the refrigeration circuit is recovered, and then the refrigerant is adsorbed on the activated carbon to be recovered.

Abstract: There is disclosed a medicine supply apparatus which can improve the efficiency of a dispensing operation. The medicine supply apparatus comprises a plurality of tablet cases 3 stored in a main body case storage part, each tablet case including a container 51 for containing medicines, and a discharge drum 53 for discharging the medicines one by one from the container 51, and the container 51 is provided with a residual amount sensor 58 for detecting that the residual amount of medicines in the container 51 is lowered to indicate a predetermined value.

Abstract: Apparatus for filling a solid drug, such as tablets, into a predetermined vial includes a rotary plate with a plurality of receiving sections formed on the upper surface of this rotary plate. The receiving sections are disposed under a plurality of tablet cases for receiving the solid drugs discharged from the tablet cases. Discharge orifices are formed through the bottom portions of the respective receiving sections and a chute guides the solid drugs from an orifice to a predetermined vial. A shutter opens or closes this orifice or the chute. When the solid drug is discharged from the tablet case, the rotary plate is rotated by a control device to adjust the position of the receiving section as the solid drug falling from the tablet case is dropped in the predetermined receiving section.

Abstract: A medication filling apparatus which is capable of preventing medications from being over-dispensed so as to enable accurate filling operation. The medication filling apparatus is equipped with: a tablet case for holding medications; a dispenser drum for dispensing the medications one at a time from the tablet case as it rotates; a motor for driving and rotating the dispenser drum; a sensor for detecting the medications which have been dispensed; and a controller which starts the motor, counts the dispensed medications according to an output of the sensor, and stops the motor when a predetermined count value is reached. The controller drops the voltage applied to the motor before the predetermined count value is reached and then short-circuits the terminals of the motor when the predetermined count value is reached.
