Abstract: PURPOSE:To prevent the damage of a device due to heat generation of an exciting lamp, to improve safety, and to reduce the size, the weight, and the cost of a device by providing a switching means to switch the value of a current, fed to the exciting lamp, from a minimum value necessary for the exciting lamp to maintain discharge to a value necessary to produce a preset given laser beam output. CONSTITUTION:In the OFF state of a change-over switch 15, a control unit 4 issues a command to a source unit 3 and controls a current fed to an exciting lamp 8 so that the current is regulated to a minimum value I0 necessary to maintain stable lighting. when an operator performs medical treatment by means of laser beam, by changing over the changeover switch 15 to an ON-state, a control unit 4 switches a current, fed to the exciting lamp 8, from a threshold I0 to a value I2 at which a laser beam output set by an output regulating knob 12 is generated. As a result, the exciting lamp 8 is increased in emission intensity and in a light output, and by strongly exciting a laser rod 7, a laser beam output is increased to a set level. Thereafter, since when the operator steps on a foot switch 13, a shutter 11 opens a light pass, laser beams can be lead from a transmission mirror 10 through a laser probe.

Filed: 1983-12-22
Abstract: PURPOSE:To enable to improve the reliability of a semiconductor device as well as to upgrade the yield thereof by a method wherein, when an interlayer insulating film to be used for insulation-isolating conductive layers is formed, a polycrystalline Si film containing impurities is deposited first on a conductor layer by a low-pressure CVD method and the polycrystalline Si film is converted into an oxide by performing a thermal treatment. CONSTITUTION:Thick field oxide films 8 are formed one by one in the peripheral parts of a P type semiconductor substrate 1, N<+> type regions 2 and 3 are formed by diffusion in the surface layer part of the substrate 1 being surrounded with the oxide films 8 and a gate electrode 5 consisting of polycrystalline Si is provided between these regions 2 and 3 through a gate oxide film 4. Then, a polycrystalline Si layer 6 of a thickness of about 500-3,000Angstrom is deposited on the whole surface by a low-pressure CVD method. The reason why the low-pressure CVD method is applied here is that the film thickness of the polycrystalline Si layer 6 is not unirformly formed by the CVD method and the reason why the SiO2 film is directly adhered is that the excellent electrical insulating properties are not obtained. After that, N type impurities are doped on the layer 6 for accelerating the rate of thermal oxidation, a thermal treatment is performed at low temperatures of 700-900 deg.C and the layer 6 is converted into an interlayer insulating film 6. Then, apertures are bored in the insulating film 6 and Al wiring layers 7 are respectively installed on the regions 2 and 3.
