Abstract: An electric discharge machine and an electric discharge machining method for the electric discharge machine are provided. The electric discharge machine includes a circulation pump for pressure-feeding a work fluid in a dirty fluid tank to a filter; a jetting pump for pressure-feeding the work fluid in the clean fluid tank to a jetting nozzle; a feeding pump for pressure-feeding the work fluid in the clean fluid tank to the work tank; and a pump controller for inverter-controlling the circulation pump, the jetting pump, and the feeding pump. The pump controller includes a jetting pump controller configured to set an inverter frequency of the jetting pump, and a feeding pump controller configured to acquire the flow rate of the inverter-controlled jetting pump and set an inverter frequency of the feeding pump based on the flow rate of the inverter-controlled jetting pump.

Abstract: An improved method for detecting antibodies is disclosed. The method employs a recombinant denatured bacterial enzyme. The invention also relates to a test kit useful for performing an immunoassay which comprises a container containing a denatured recombinant bacterial enzyme.

Abstract: A frame synchronizer for a television receiver in which the incoming television signal is digitized and stored in a memory, includes a circuit for generating a write-inhibit control signal for inhibiting the write-in of a digitized second television signal into the memory between the switchover from a first television signal to the second television signal and the beginning of a complete frame of the second television signal.
