Title: Laser equipment
Inventor: YOSHIDA TOSHIO
IPC: H01S3/08
Filed: 1986-10-23
Abstract: PURPOSE:To make it possible to detect easily and accurately the state of absorp tion loss of a mirror or a window which controls the oscillation efficiency of a laser, by providing a light source radiating light to a mirror constituting a resonator or a window to take out a laser light, and arranging a photodetetor on the path of transmitted light through the mirror or the window. CONSTITUTION:A light source 8 and a photodetector 7 are provided. The former radiates light from the outside of a traveling path of laser light 5 to a mirror 3 constituting a resonator or to a window to take out the laser light. The latter is arranged on the path of a transmitted light of the light source 8 through the mirror 3 or the window. A part of the light radiated on the partial reflection mirror 3 by the light source 8 is absorbed, its amount depends on the state of absorption loss of the mirror 3, and the residual part of the light is reflected and transmitted. Thus the light containing the information of the sate of absorp tion loss of the mirror 3 is transmitted. The transmitted light enters the photode tector 9, its quantity is determined, and the absorption loss is determined. In this case, the measurement accuracy can be more improved in providing the photo detector 9 with a frequency filter which passes selectively a light having a wavelength which is specially absorbed by deposition on the mirror 3.

Abstract: PURPOSE:To decrease the electric power to be used in a melt refining station by disposing plural having stations in parallel and extending the heating time for the raw materials in plural arc furnaces in the stage of circulating the raw materials through the four stations; raw material charging, preheating, heating and melt refining stations of the arc furnaces and producing a molten steel from scrap. CONSTITUTION:Carriages 3 on which the plural arc furnaces 2 are installed are moved in an arrow direction on an annular moving path L formed of rails 1. The raw material scrap is charged into the furnace 2 in the 1st station S1 on the annular moving path L and the high-temp. waste gas formed by burning the CO-contg. gas generated from the melt refining stage of the 4th station S4 in a combustion column 11 is introduced through a duct 12 into the furnace to preheat the scrap in the 2nd station S2. The 3rd stations S3 are disposed in plurality in parallel and after the scrap is heated for a long period by kerosene burners, etc., the scrap is melted by a transformer 10 and an electrode 9 in the 4th station S4. The molten steel refined in such a manner is tapped from the furnace. Since the number of the 3rd stations S3 is large, the heating time by the kerosene is extended and the temp. of the scrap is increased. The electric power consumption in the 4th station S4 is thus reduced.

Filed: 1987-10-09
Abstract: PURPOSE:To obtain a magnetic disk capable of propagating data accurately and stably by deciding amplification factors for plural magnetic heads in order to reduce their reproducing signal level differences and amplifying them accordingly. CONSTITUTION:Only the reproducing signal of a magnetic head selected by a selecting circuit 4 is inputted via an amplifier circuit 3 to an automatic gain amplifier circuit 5 to be amplified based on a signal of a gain control circuit 11. The amplified reproducing signal is operated for its gain value by an arithmetric circuit 10 via a A/D converter 9. The operation is repeated and when the gain value falls within a set range, the similar process is repeated for the next magnetic head 2. Thus extending to all magnetic heads. The magnetic recording medium 1 falls into its radial blocks and the amplification factor is decided for each magnetic head in order to eliminate its reproducing signal level difference on each block, and the gain value of each head for each block is stored respectively. By this constitution, even at the initial changeover time of the magnetic heads, the variation of the reproducing signal level is minimized, thus propagating accurately the reproducing signal.
