摘要： The absolute position measuring device comprises a main body, a spindle provided movably in the main body, two sets of rotary encoders, an arithmetical operation section, and a display section. The rotary encoders originate two phase signals of different periods in accordance with the amount of movement of the spindle. The arithmetical operation section makes arithmetical operation on the phase signal to obtain the absolute position of the spindle. The display section displays the absolute position in digital format. The two phase signals have a different phase difference at a different position of the spindle. The arithmetical operation section comprises phase signal processing section for comparing the two phase signals to obtain a phase difference between the phase signals, and absolute position calculating section for calculating the absolute position of the spindle from the phase difference obtained by the phase signal processing section.

摘要： A control system for an internal combustion engine is provided for a running equipment, which prevents from running in the direction opposed to the driver's intention when reversing the engine is failed although a driver executes a reverse process of reversing the rotative direction of the engine. The rotative direction of the internal combustion engine is detected so as to generate a rotative direction detection signal, and a reverse failure signal is generated when the rotative direction of the engine detected by these detection signals does not correspond to the rotative direction of the engine commanded by a reverse command. When the reverse failure signal is generated, fuel supply to the engine is stopped, and the engine is extinguished so as to stop the rotation.

摘要： A rotational direction change-over control method capable of reversing a rotational direction of an internal combustion engine without discharging unburnt gas. When a reverse command is generated, feed of fuel to the engine is interrupted to reduce a rotational speed of the engine to a set level. An ignition position of the engine is advanced to an excessively advanced position during a reduction in rotational speed to the set level. When the rotational speed is reduced to the set level, feed of fuel is restarted to reverse a rotational speed of the engine. When judgment that the rotational speed is successfully reversed is made, the ignition position is transferred to a position near a top dead center, to thereby maintain rotation of the engine in a direction reversed.

摘要： A gas laser has an electrode of improved construction. The electrode, for example a cathode, comprises an inner cathode and at least an outer cathode spaced from the inner cathode and disposed on the side thereof away from to an anode. Each of the cathodes has a central hole from which glow discharge is formed, and the outer cathode further has a plurality of through-holes around the central hole. A gas medium flowing in a discharge tube passes through the central hole of the inner cathode via the central hole and through-holes of the outer cathode. The gas medium forcedly enters the glow discharge from the inner cathode thereby to cause it expand and a part of the gas medium having passed through the through-holes of the outer cathode squeeze the glow discharge from the outer cathode so that the glow discharge can enter the glow discharge from the inner cathode. Therefore, the current density of the glow discharge in the discharge tube is made information.

摘要： A laser beam axis monitoring apparatus which includes a laser oscillator generating a laser beam and a light generator for generating a light for monitoring an axis of the laser. The light from the light generator is split into ring-shaped light and reflected or lead into the laser oscillator. The light in the laser oscillator is reflected by a total reflection mirror and passes out of the oscillator so that the axis of the laser beam and axis of the light coincide with each other.
