    摘要： A laser oscillator control device includes a controller having a transmitter section and a receiver section; a laser oscillator having a transmitter section and a receiver section and communicating with the controller via a communication line; wherein the laser oscillator control device outputs a control signal from the controller to the laser oscillator, based on a status signal indicating operational state of the laser oscillator sent from the laser oscillator to the controller. The controller has an alternating signal transmitter circuit that generates an alternating signal that changes at a predetermined period, and sends this alternating signal to the laser oscillator, and the laser oscillator has a return signal transmitter circuit which generates a return signal that changes periodically in correspondence to the alternating signal from the controller, and sends this return signal to the controller. Furthermore, the controller has a monitoring circuit monitoring the return signal from the laser oscillator, and if it determines that there is an abnormality in the return signal, outputs a stop control signal for stopping laser beam irradiation by the laser oscillator.

    摘要： A gas laser oscillator (2) that excites a laser gas to generate laser light includes a circulation path (9) for the laser gas, a circulation means (14) for circulating the laser gas through the circulation path, a pressure detection means (16) for detecting the pressure of the laser gas in the circulation path, an electric power detection means (11) for detecting electric power to drive the circulation means, a storage means (35) for storing the relationship between the pressure of the laser gas and the electric power of the circulation means during the period of normal operation of the circulation means for each kind of the laser gas, and a laser gas determination means (31). The laser gas determination means determines the kind of the laser gas based on the pressure of the laser gas and the electric power of the circulation means detected during the period of normal operation of the circulation means, and the relationship between the pressure of the laser gas and the electric power of the circulation means stored in the storage means. Due to this, the laser gas is determined without generating a discharge voltage. If the laser gas cannot be determined, it may be possible to judge that the laser oscillator is anomalous.

    摘要： The present invention provides an electric compressor in which a lead wire on the motor driving circuit side can be electrically connected positively to a sealed terminal. Because the sealed terminal is formed from a terminal body which is made of a metal having electrical conductivity and whose end is provided with a male threaded portion, and a joining nut made of a metal having electrical conductivity and which is different from the material for the terminal body, and is threadably mounted on the male threaded portion of the terminal body, it is possible to positively join the joining nut of a different material to the terminal body and to positively join the lead wire of the same material as the joining nut to the joining nut by welding, whereby it becomes possible to electrically connect a lead wire on the driving circuit housing chamber side positively to the sealed terminal.
