摘要： PROBLEM TO BE SOLVED: To provide an inspection device that facilitates inspecting the video playback function of a device to be inspected only by output of any video without needing any means for measuring an audio output.
SOLUTION: A video signal pattern for inspection, in which gradation changes in a given direction for every video frame at a given speed, is input to a device 2 to be inspected. A video signal played back by the device 2 to be inspected is captured as frame image data for each video frame by an image capturing part 32. An average gradation value is calculated by an average density calculation unit 34. Then, whether the vide reproducing function of the device 2 to be inspected is good is determined by a decision unit 36 based on inclination of the average gradation value with respect to the capturing time.

摘要： PURPOSE:To suppress the acceleration of a motor at the time of switching to a commercial power source by inserting a reaction into the feeder circuit of the motor immediately after the power source is switched either from the commercial power source to a variable frequency power source or vice versa. CONSTITUTION:A reactor 14 and switching means 15 connected to the reactor 14 are inserted into a common feeder circuit for a system for driving a motor 5 by a commercial power source 7 and a system for driving a motor 6 by a variable frequency power source 8, and the motor 6 is driven through the reactor 14 only for a predetermined period of time after the power sources are switched in the switching between the above two systems in bidirections. Thus, the reactor 14 suppresses the accelerating speed of the motor 6 when the power source 8 is switched to the power source 7 to allow a damper to sufficiently follow up the switching of the power sources.

摘要： PURPOSE:To suppress a load variation during speed changing and suppress a starting current by inserting a reactor in a power circuit for a motor. CONSTITUTION:A switch 11A is closed at normal state either in high speed or in low speed, and is controlled to be opened by a prescribed time when a pole change motor 6 is started and when it is changed from low speed to high speed. Consequently, a reactor 10A is temporarily inserted in a power circuit when the pole change motor 6 is changed from low speed to high speed and when it is started, thereby a load variation during the speed changing can be suppressed and a transient overcurrent during the starting can be suppressed.

摘要： PURPOSE:To prevent a thermal damage of a motor by stopping switching by detecting by a temperature detector until the quantity of heat stored in the motor is returned to sufficiently normal state when a variable frequency power source is switched to a commercial power source. CONSTITUTION:A large torque might be generated by the rotating speed operated by a variable frequency power source 2 before switching to a commercial power source 1. Thus, a current flowed at switching time is increased, and heat is stored in a motor 6 at switching time. Thus, when the power source 2 is switched to the source 1, the switchings of switches 3, 4, 5 are locked if a temperature detector which operates when the temperature of the motor is the prescribed value or higher is operated, thereby preventing the motor from abnormally overheating.

摘要： PURPOSE: To perform an energy-saving, a reduction of a cost by following via a variable frequency source (V power source) at load increase request time, and following via a mechanical control mechanism at load reduction request time, thereby eliminating the regenerative brake.
CONSTITUTION: The fact that, when the output frequency of a V power source 2 is altered to vary the control responding speed and the opening θ of a vane 6, and the control responding speed is compared, the vane control is fast at wind amount reducing time and slow at wind amount increasing time is aimed to increase the frequency of the power source 2 to first respond when the load (wind amount) increases and to respond to reduce the opening θ of the vane 6 and to then reducing the frequency at load decreasing time, the frequency is then decreased to return the opening θ of the frequency to the original position, thereby accelerating the increasing response of the wind amount.
