摘要： An indirect address type interrupt control circuit is provided. A plurality of interrupt control units are provided for receiving an input interrupt signal and generating a vector address which corresponds to the interrupt signal. Also provided in the circuit is a control unit which responds to the input interrupt signal to cause only one of the plurality of interrupt control units which corresponds to the interrupt signal to be rendered operative. With this structure, the number of interrupt request signals can be increased or decreased with ease.

摘要： An inkjet recording head having a head substrate (1); at least a group of pressure chambers (2) arranged so as to be recessed over an entire surface of the head substrate; ink ejecting nozzles (7), each of which is opened so as to face a surface opposite to that of the substrate by extending through a flow path (5) that passes through the head substrate thicknesswise from one end of each of the pressure chambers; and an annular ink preparation chamber (4) communicating with the other end of each of the pressure chambers. The ink preparation chamber that communicates with each of the pressure chambers is arranged so as to be annular, thereby improving the air bubble discharging characteristics and preventing disruption of ink ejection. In addition, the advantage that the ink can be supplied to each of the ink ejecting nozzles uniformly ensures excellent printing quality. Furthermore, the ink chamber is recessed into an opposite surface of the head substrate opposite the pressure chambers.

摘要： An optical pulse waveform shaper capable of providing an optical pulse waveform of a desired intensity distribution with little loss. The optical pulse beam split by a beam splitter is directed into the beam splitter with a phase difference to combine with the transmitted optical pulse beam. The phase difference is controllable. The optical pulse waveform shaper is applicable between a laser oscillator with different exciting conditions and an amplifier.

摘要： In a metal vapor laser, (e.g. copper vapor laser), the innermost heat shield (15) of Mo, Ta or W, which is disposed with a predetermined gap (preferably sufficiently larger than 0.3 mm) to the outer surface of the seal tube (8), is connected at respective ends to the anode terminal (2) and the anode (5), so that inductance of discharge load is considerably decreased.
