Abstract: A communication section (9) has a piercing needle (8) capable of piercing through a piercing section (11) of a solute container (10) storing therein a solute such as a drug, and a closing section (7) which is separable inside a storage chamber (2) storing therein a solvent. The communication section (9) is disposed between the solute container and the storage chamber, and a bellows-like guide cover (12) 'covers the piercing needle. Accordingly, the piercing needle is positively kept separated from the piercing section when not in use and the guide cover undergoes plastic deformation under an external force exceeding a predetermined value when in use, thereby permitting the piercing operation to be initiated and then maintained. Due to the subsequent separation of the closing section, the solute and the solvent are mixed through the communication section and sterile dissolution can be ensured.

Abstract: A refrigerating absorption system which is mounted on vehicles with internal combustion engines utilizes the exhaust gas of the engine as a source of heat. In a preferred embodiment of the invention the system comprises two reaction pots (1,2) which are heated by the exhaust gas when these operate as generators, and they are cooled by the air when they act as absorbers; each of these reaction pots contains a solid absorber impregnated with an absorbed fluid (gaseous or liquid) which circulates, when the reaction pots is heated, within a sealed circuit (10,20) consisting of a condenser (11,21) and an evaporator (14,23). The evaporator absorbs heat from a fluid (13) which is utilized as a cooling unit. A reaction pot operates as a generator when a valve (3), which intercepts the exhaust gas of the vehicle, deviates that gas into the above-mentioned reaction pots, otherwise the reaction pots operates as an absorber. The refrigerated fluid (13), through pipes (40,42), reaches the vehicle radiator (38) communicating with the interior of compartment vehicle and produces the cooling.

Abstract: Soldering of surface mount connector terminals to contact pads (41) on circuit board (40) is facilitated by configuring the terminals (33) and their solder tails (39) as spaced integrally-formed projections of a selectively actuable heater. Thermal energy developed in the heater(35) is conducted along the projections to the solder tails (39) to melt fusible conductive material (e.g., solder, at the connection sites). After cooling, the projections are severed from the heater (35). The terminals (33), which are formed at the distal ends of the projections, are typically supplied partially inserted in respective terminal-­receiving passages (31) of the connector housing (30). After the soldering operation, the terminals (33) are fully inserted into the passages (31). The heater (35) is preferably a self-regulating heater in the form of a copper substrate having a skin layer (13) of magnetically permeable, high resistance material. An alternating current of constant amplitude and high frequency is passed through the heater (35) and concentrated in the skin layer (13) at temperatures below the Curie temperature of the skin layer material. At higher temperatures, the current is distributed through the lower resistance substrate to limit further heating. During the time interval required for the surface layer (13) to reach its Curie temperature, the resistive power dissipation creates thermal energy that is conducted to the solder tails (39).
