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.

Emergency lighting with a charging indicator circuitry comprises a power source module, a lighting circuit, a battery circuit, and an emergency switch circuit. The battery circuit includes charging indicator circuitry and a battery module; the power source module is connected with the battery module via the charging indicator circuitry. When the utility power is interrupted or a test switch is pressed, the light of the charging indicator circuitry goes out to indicate that the emergency lighting is in discharging status. When the utility power is supplied normally, if a battery within the battery module is in disconnected state, the light of the indicating circuitry goes out to indicate that the emergency lighting is in disconnected state. The charging indicator circuitry may be a simple light-emitting indicating circuit, has no need for much modification to the original circuit during manufacture and design, and may be simple and quickly-responsive.

An apparatus for and a method of controlling battery discharge. A number of battery switching operations is minimized by detecting a remaining voltage capacity of each of a plurality of batteries supplying a battery-powered electronic device with power. The remaining voltage capacities of an internal battery and an external battery are detected and corresponding flags are set for the internal and external batteries according to predetermined conditions. A discharge status of at least one of the internal battery and the external battery is controlled by referring to the flags and a remaining voltage capacity of each of the internal battery and the external battery.

A master controller of a battery charge and discharge control apparatus is a device performing charge and discharge control on a group of a predetermined number of battery arrays, the battery arrays being connected together in parallel. The master controller acquires an entire charge or discharge instruction intended for the entire battery array group, starts charging or discharging each of the battery arrays at a uniform charge or discharge power value, acquires a charge or discharge status of each of the battery arrays after the beginning of the charge or discharge and compares the charge or discharge status with a predetermined charge or discharge set value for the entire battery array group, and changes the charge or discharge power value of each of the battery arrays based on a result of the comparison.
