摘要:
A linear motor is capable of reducing cogging which may be present in the motor. Cogging is an obstruction in realizing constant speed control or high accuracy of position control. The reduction of cogging is accomplished for example by pole location or specific detailed shaping of pole iron plates.

An image recording apparatus includes a discharge head and a discharge control device. The discharge head includes an ink chamber with a discharge hole, a first heater for heating and gasifying ink, a shutter unit, provided at the discharge hole portion, controlled to discharge gasified ink intermittently according to an electrical signal corresponding to image data to be recorded, and a first member for maintaining the temperature of the discharge hole sufficiently lower than the temperature of the first heater in operation of the first heater before initiation and after completion of image data recording. The discharge control device controls the shutter unit.

A second heating device heats an inner wall of an ink chamber of a print head to a temperature not lower than the melting point but not higher than evaporating temperature of ink 3, for a prescribed time period after the end of printing, based on a signal from a second heating control device. Consequently, the ink solidified and deposited on the inner wall of ink chamber and not used for printing is liquefied and recovered to the ink chamber to be used for the next printing.

The invention concerns a phase locked loop speed control circuit for controlling the speeds of two or more objects. It includes pulse generators for generating reference pulses, first counters for counting each of these reference pulses, encoders for detecting relative travelling distances of the objects, second counters for counting encoder pulses from the encoders, first subtracters for subtracting the outputs of the second counters from those of the first counters, second subtractors for subtracting the encoder pulses from the reference pulses, corrector sections for correcting the differences output by the first and the second subtractors, and adjusting sections for adjusting the movements of the objects based on the corrected differences.

In a linear motor comprises one or more moving units provided to move linearly on a base frame, one or more magnetic field forming members to opposed each of the moving units, and moving means provided on said magnetic forming members for moving the magnetic forming members on the base frame by reaction force occurring when the moving units are driven, whereby vibration acting on the base frame at the time of moving of the linear motor can be cancelled by the motion of the magnetic field forming members.

A linear driving apparatus is provided wherein the driving output of a linear driving apparatus is adapted to be properly varied in the constant speed condition and the high acceleration condition for a moving object. Thereby the closer controlling operation may be effected not only in the high acceleration condition, but also in the constant speed condition if there is a considerable difference on the driving output of the linear driving apparatus in the constant speed condition and the high speed condition.

A game machines has a back side display unit composed of reels for displaying back patterns, and a front side display unit composed of transparent EL panels for displaying overlapping patterns overlapping with the back patterns. The back side display unit and the front side display unit are disposed not to produce blind spot regions of the back patterns. The game machine can provide various overlapping patterns with good visibility and a high game selection capability to a player.
