An analog switch device has p- and n-channel metal oxide semiconductor field effect transistors, each having a source electrode, a drain electrode, a gate electrode and a substrate electrode. The p- and n-channel metal oxide semiconductor field effect transistors are connected parallel to each other. First and second analog signals are received and produced at a pair of nodes between the p- and n-channel metal oxide semiconductor field effect transistors. Control signals which are inverted with each other are respectively supplied to the gate electrodes of the p- and n-channel metal oxide semiconductor field effect transistors. A voltage buffer circuit is provided for applying a predetermined voltage to the substrate electrode of one of the p- and n-channel metal oxide semiconductor field effect transistors so as to decrease a change in a threshold voltage due to the source-substrate bias effect.

Disclosed is an electric blower having a stator, a rotor, a bracket, a rotary fan, an air guide and a fan case. The air guide comprises a partition plate, a diffuser disposed around outer periphery of the rotary fan in the air guide, a partition-plate sloped portion and a guide vane. The fan case has a fan-facing portion, a fan case shoulder bent at the outermost part of the fan-facing portion, and a cylindrical portion extending cylindrically in an axial direction from the fan case shoulder. The fan case shoulder is so bent that it forms substantially a right angle.

An electric blower includes a motor having a stator on which field windings are wound, a rotor facing the stator, and a bracket covering the stator and the rotor. The electric blower further includes a fan mounted to a shaft coupled to the rotor, and an air guide having a diffuser provided to the outer circumference of the fan and formed of a plurality of stationary blades adjacent to each other. The electric blower still includes a fan case having openings at its outer circumference for discharging a part of the air having passed the diffuser to the outside, and protrusions having a brim for covering a part of the openings. The foregoing structure allows the air blower to cool the motor with airflow generated by the fan.

A TFT readout system radiation image detector capable of satisfactorily removing noise signals generated by the parasitic capacitors formed in the vicinity of the respective intersections between gate control signal lines and charge signal lines. The detector includes charge detecting elements for storing charges generated by receiving radiation; gate control signal lines through which a gate control signal flows to control the switching element of each charge detecting element; charge signal lines to which charge signals stored in the storage sections flow out; and delay circuits provided for the switching elements of respective charge detecting elements to delay the rise time of the gate control signal. Charge signals flowed out to the charge signal lines after the rise time are detected to differentiate the detection timings of the charge signals, and noise signals generated a when outputting of the gate control signal is initiated.
