摘要： Proposed is dispensing technology capable of reliably spotting a biological sample on a solid phase. A head chip applies a voltage pulse between a diaphragm and separate electrodes based on a drive control signal output from a head driver IC, and discharges a solution containing protein filled in a pressurized chamber as a result of the elastic deformation of the diaphragm. A drive pulse generation circuit generates a drive voltage pulse and supplies this to the head chip in order to discharge a solution containing protein from the head chip. The drive current detection circuit detects a drive current flowing between the diaphragm and separate electrodes. Since the waveform of the detected drive current and the peak current value and so on differ in the case where the discharge status is normal and in the case where it is abnormal, a defective discharge can be discriminated by detecting such change.

摘要： An ink jet head includes a common electrode formed on a semiconductor substrate. A charge is applied to the common electrode and an electrode disposed on another substrate in opposition to a diaphragm formed in the semiconductor substrate to electrostatically deform the diaphragm and eject ink. The common electrode comprises a single layer or multiple layer metallic coating forming ohmic contact on the semiconductor substrate. In addition, a group III or group V element is doped to a high concentration at the area on the semiconductor substrate where the common electrode is formed. The diaphragm can therefore vibrate at high speed. An ink jet head capable of high speed printing can be provided because supply and elimination of the charge to the diaphragm can be accomplished at high speed.
