    摘要: A lead frame having thereon a plurality of semiconductor devices is prepared by immersing it in a flux solution to activate the lead frame surface and to remove oxide film. The lead frame is then transferred to a coating block unit, and the lead frame is moved along a lateral passage which extend through the coating block unit. During movement through the passage, the lead sections of the lead frame are coated on both upper and lower surfaces thereof with liquid solder which ascends by capillary action along a slit which projects upwardly from a liquid solder bath and communicates with the passage. The solder in the slit, where it communicates with the passage, is continually replenish by capillary action from the bath as the solder coats the lead sections as the lead frame moves through the passage.

    摘要: A fuel cell system (1) of the present invention includes a fuel cell stack (10) including plural single fuel cells (11) stacked on each other, each single fuel cell being supplied with hydrogen gas and air to an anode electrode (14) and a cathode electrode (13), respectively, to generate electricity. The system (1) further includes a voltage applying device (C9) that applies voltage to the fuel cell stack (10) after oxygen present in the cathode electrode (13) is reduced. The system (1) further includes a cross-leakage diagnosis device (C12) that diagnoses, based on voltage of the single fuel cells (11) when the voltage applying device (C9) applies the voltage to the fuel cell stack (10), whether hydrogen gas in the anode electrode (13) is cross-leaked to the cathode electrode (14) in each single fuel cell (11).

    摘要: An ice blasting apparatus comprises: an ice making device operating a cutting blade to shave off ice freezing on an inner wall of the freezing casing and continuously discharges the shaved ice as flake-shaped ice pellets; an ice mixing tank mixing the ice pellets and water and maintaining the resulting ice slurry at a predetermined concentration with a concentration sensor; and a blast gun blasting the ice slurry. A trimming method is performed on a film insert molding with a film material adhering to a face of a resin molding and extending beyond a periphery edge of the resin molding. A blast gun facing the face with the film adhering to it blasts ice slurry of a required concentration toward the vicinity of the periphery edge of the resin molding to remove the unnecessary portion of the film material extending beyond the periphery edge of the resin molding.

    摘要: An automatic equalizer comprises a transversal filter connected to receive an input signal such as a television signal in which a predetermined periodic reference signal is present and having variable tap gains, and a correlator for forming the correlation between the input and output signals of the transversal filter and correcting the tap gains of the transversal filter to cancel out distortion components such as ghost component contained in the input signal. For the purpose of preventing the slow convergence and fluctuation of tap gains of the transversal filter due to non-periodic noise components contained in the input signal, a circuit is further provided to integrate a predetermined portion of the waveform of the reference signal contained in the input signal. An output signal of the waveform integrator circuit is correlated with the output signal of the transversal filter by the correlator.

A first input terminal is connected via a resistor to the base of the first transistor, a second input terminal is connected to the base of the second transistor, and the emitters of the first and second transistors are connected to one terminal of a first current source. A current mirror circuit including third and fourth transistors of the complementary type to the first and second transistors is connected between the collector of the second transistor and one terminal of a second current source which has a current capacity substantially half that of the first current source. The other terminals of the first and second current sources ar connected together and a fifth transistor of the same type as the third and fourth transistors is connected between the collector of the first transistor and a power source terminal and the base of the fifth transistor is connected to the one terminal of the second current source.
