Abstract: Disclosed is an optical pumping-type solid-state laser apparatus in which a semiconductor laser device is used as a light source for optical pumping. The solid-state laser apparatus includes first and second photodetectors. The former detects the amount of light emitted from the semiconductor laser device, and the latter detects the amount of laser light transmitted through a filter plate which has the same light-absorbance characteristics as that of the solid-state laser. In accordance with the detected results, a driving circuit drives the semiconductor laser device to obtain a laser beam with an appropriate output level and a temperature regulator regulates the temperature of the semiconductor laser device so that the wavelength of the laser light to be emitted therefrom is accurately adjusted to be the same as that of the light to be efficiently absorbed by the solid-state laser. The laser beam with the accurately adjusted wavelength is used for optically pumping the solid-state laser.

Abstract: A wet-process stack gas purification method and apparatus wherein stack gas is scrubbed by bubbling it into a first scrubbing liquid while maintaining the level of the first scrubbing liquid. The above scrubbed gas is subjected to a counter-current contact with a second scrubbing liquid in a scrubbing tower to further purify the gas. The method and apparatus can attain a highly remarkable decontamination effect, and the apparatus is simple in structure and small in size.

Abstract: A toilet seat structure capable of automatically feeding a seat covering paper onto a toilet seat substantially comprises a seat covering paper roll disposed at the rear end of a toilet seat body, a seat covering paper feeding mechanism which is provided with a press plate, a seat covering paper tearing mechanism, a control unit for controlling the seat covering paper feeding mechanism and the seat covering paper tearing mechanism and tension applying means for applying tension to the seat covering paper, wherein the seat covering paper which is subjected to tension is cut by applying a pressure thereto by means of the press plate. Due to such construction, the tearing edge of the press plate can be formed in a round shape so that wear of the cutting edge which is generated through the tearing operation can be miminized whereby maintenance or repairing can be also minimized.

Abstract: The invention eliminates polarization problems and feeder waveguide loss in a miniature microwave transmitter/receiver. This is done by providing a massive heat sink, metal housing with a primary radiator which is rotatably mounted on the end of the housing. Polarization is accomplished by rotating the radiator on the housing. Inside the housing there is a hybrid of integrated circuits mounted on internal parts of the housing which provide both heat sinking and waveguide functions.
