    Abstract: PROBLEM TO BE SOLVED: To provide an oscillation circuit which precisely adapts an oscillation frequency to the resonance frequency of an electronic device supplying power and corrects the oscillation frequency so that the value of the device falls within the range of allowable error through the use of the minimum number of circuitry. SOLUTION: In a circuit device containing an oscillation circuit 1, and the series arrangement of a resistor R1 and a capacitor C1 and where the series arrangement determines the oscillation frequency of the oscillation circuit 1, a resistance coupling R2 whose output supplies a control signal showing the oscillation mode of an electronic device 2 is provided between the control signal output S of the electronic device 2 and series arrangement. The resistance coupling R2 is provided between the series arrangement of the resistor and the capacitor C1 and the control signal output S of the electronic device 2 supplying power and the control signal output of the electronic device 2 supplies the control signal showing an oscillation mode and therefore the oscillation frequency of the oscillation circuit 1 can sufficiently be adapted to the resonance frequency of the electronic device 2. Then, the allowable error of the electronic device 2 can sufficiently be corrected.

    Abstract: PROBLEM TO BE SOLVED: To provide a high pressure gas electric discharge lamp having at least one electrode (HID or UHP lamp, or lamp filled with 0.05-0.5 mg/mm3 of mercury in general) capable of stably moving in a roughly permanent interelectrode distance along the whole of a period of an operation life. SOLUTION: For example, spherically thickened parts 9, 10 are provided on an end inside a lamp container 2 on the electrode. These parts are made in dimensions corresponding to diameters of an action parameter of the lamp and/or an electrode rod, and it is devised so that an electrode tip is independently formed on this part during first time of action of the lamp. This tip grows from the above part until its free end starts to melt. This tip is of a self-adjusting type and an optimum mutual interval of the electrodes can be maintained through the lamp life period. Additionally, a manufacturing method of such the lamp is mentioned.

    Abstract: The invention relates to a circuit arrangement for operating a lamp comprising: circuit input terminals for connection to a supply voltage source; an inverter coupled to said circuit input terminals for generating an AC voltage with a frequency f out of a supply voltage supplied by the supply voltage source and equipped with inverter output terminals; a piezotransformer comprising transformer input terminals, coupled to the inverter output terminals, and transformer output terminals; terminals for lamp connection coupled to the inverter output terminals; a detector for detecting whether the lamp has ignited. In accordance to the invention the transformer input terminals are connected to the inverter output terminals only by means of passive components and in that the inverter comprises means coupled to the detector for changing the frequency f in response to the ignition of the lamp. As a result the circuit arrangement is simple and inexpensive and need not comprise means for switching the piezotransformer out of the circuit after ignition of the lamp.

    Abstract: A short-arc discharge lamp (1) is provided with a translucent lamp vessel (10) which is closed in a gas-tight manner and which is provided with an ionizable fill. A first and a second electrode (11a, 11b) are arranged in the lamp vessel (10) which are each connected to its own current conductor (12a, 12b) which extends to outside the lamp vessel. A starting antenna (2) is arranged near to the lamp vessel, which antenna is connected to a further current conductor (24). The starting antenna comprises an antenna container (20) and a further electrode (22) which antenna container (20) is closed in a gas-tight manner and contains an ionizable fill, the further electrode (22) being connected to the further current conductor (24). This makes it possible to realize a shorter reignition time by means of a higher reignition voltage on the starting antenna while spark-over from the starting antenna (2) to the lamp vessel (10) is avoided.
