    摘要： A micro-displacement measuring apparatus using a semiconductor laser, comprises a compound resonator system containing the semiconductor laser, and a light detector receiving a light from said semiconductor laser. The compound resonator system is constructed such that a light from the semiconductor laser irradiates an object to be measured and the reflected light therefrom returns to the semiconductor laser, wherein the relationship between the reflectivity R.sub.f at the front facet of the semiconductor laser from which a laser light irradiates the object, and the reflectivity Rr at the rear facet of the semiconductor laser which is opposite the front facet is as follows: 0.1

    摘要： Finely-divided particulate bismuth oxide is produced by the steps of heating bismuth at 800.degree. C. or above in a first compartment of a sealed vessel divided into two compartments by a partition wall, the two compartments communicating with each other by a hole provided on the partition wall, feeding an inert gas such as nitrogen and argon into the first compartment so that the bismuth vapor formed by heating bismuth has a bismuth concentration of 0.1 to 0.5 g/liter, blowing air into the bismuth vapor introduced from the first compartment into the second compartment through the hole on the partition wall, permitting the air to mix with the bismuth vapor to form bismuth oxide and simultaneously cooling the thus formed bismuth oxide to 250.degree. to 300.degree. C., discharging by suction the bismuth oxide from the sealed vessel at a flow rate of 1 to 5 m/sec, and cooling the discharged bismuth oxide by supplying cooling air outside the sealed vessel.

    摘要： A rear wall is detachably fitted at the rear of a body frame. A grinding wheel casing is also associated at the rear of the rear wall. A feeder wheel disposed on the front surface of the body frame and a rotatable grinding wheel provided within the grinding wheel casing are respectively rotated by a motor provided within the body frame. A cutter disposed opposite the feeder wheel cuts open a lid of a can rotated by the feeder wheel. The rotatable grinding wheel provided within the grinding wheel casing sharpens the edge of a knife inserted into the grinding wheel casing from a slit formed in a portion of the grinding wheel casing.
