There is provided a liquid medicine ejection device to eject liquid medicine into an inhalation flow path in the form of liquid droplets, thereby to allow a user to inhale the liquid medicine through a suction portion. In the liquid medicine ejection device is an ejection means, which communicates with a liquid medicine storage section, for ejecting the liquid medicine in the form of liquid droplets from an ejection opening. A pressure variable means changes a pressure in the liquid medicine storage section in accordance with a change of pressure in the inhalation flow path connected to the ejection opening of the ejection means and the suction portion. According to the liquid medicine ejection device of the present invention, it is possible to prevent ejection failure caused by a negative pressure applied to the ejection means, thereby enabling reliable inhalation.

Signals are transmitted through a plurality of transmission channels, each including at least a pair of signal lines for transmitting an interface signal, between a transmitter and a receiver. A predetermined signal is modulated by a modulator with a high-frequency signal, and the modulated signal is provided to a signal line of one of the plurality of transmission channels. A demodulator receives the modulated signal transmitted via this signal line, and demodulates the modulated signal from the signal line based on the frequency of the high-frequency signal. According to the above-described configuration, an interface control method and apparatus which can newly exchange other data and control signals while conforming to existent interface specifications are provided.

It can be determined without visually observing the display screen of a display device whether image conversion processing in a conversion circuit for outputting image data to the display device is being performed normally. The conversion circuit extracts data at a position designated from a host apparatus from image data output to the display device, and outputs the extracted data to the host apparatus. In the host apparatus, image data obtained upon normal conversion in the conversion circuit is prepared in advance, and this image data is collated with the data sent from the conversion circuit to determine whether the operation of the conversion circuit is normal.

Display control apparatus, information processing apparatus, and control

An image is displayed in an optimum state in accordance with the state of a display. For this purpose, an FLCD interface mounted in an information processing apparatus and an FLCD for actually displaying an image are connected through a data transfer bus for transferring image data to be displayed and a serial communication line for performing communications between them. When the FLCD detects a change in its own state, this information is supplied to a CPU of the FLCD interface through the serial communication line. An instruction for changing, e.g., the operating mode is also transmitted from the FLCD interface to the FLCD through the serial communication line.
