Title: Power transmission gear
Inventor: SHIMIZU RIYOUTA
IPC: H02K49/10
Filed: 1982-12-20
Abstract: PURPOSE:To aim at a reduction in both of friction loss and noise, by transmitting power to a driving gear as making the transmission act so as to cause the zones of gear tooth contact to repel each other by dint of magnetic force. CONSTITUTION:Each of gears 38 and 40 and a flywheel 30 are made up of a manganoaluminum system magnetic material, while a capstan 22, a shaft 42 and a motor shaft 36 are all made up of a nonmagnetic stainless steel material respectively so as not to receive any influence of magnetism. A tooth surface of the gear 38 to be turned to the driving side presses a tooth surface of the gear 40 to be turned to the driven side whereby transmits power to the driving side. Since individual tooth surfaces are magnetized to an S pole of the same polarity, such magnetic force as repelling this pressing force works thereat. This phenomenon works so as to reduce the surface pressure produced by the mechanical contact between tooth surfaces.

Title: Controlling method for total reflection fluorescent x-ray analyzer
Inventor: MORI YOSHIHIRO
IPC: G01N23/223
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To detect any slight failure in a fluorescence analyzer in its early stages so as to enhance the reliability of analysis by separately controlling fluctuations in excitation X-ray intensity and those in the accuracy of setting incident angle. SOLUTION: A standard sample provided by adhesion of one or more kinds of standard elements to a substrate is repeatedly measured at a certain incident angle at certain time intervals. The ratio of the intensity of a fluorescent X-ray from the substrate element to that of a fluorescent X-ray from a second freely selected element is plotted as one axis and the intensity of the fluorescent X-ray from the substrate element as the other axis. Fluctuations in excitation X-ray intensity with time are detected as the movement of a measuring point with time on a coordinate system from the substrate element and in a direction parallel to the fluorescent X-ray intensity axis.  The fluctuations with time of the accuracy of setting the incident angle are detected as the movement of the measuring point with time on a curve in the coordinate system; i.e., fluctuations in incident angle appear on a graph as the movement of the point on the curve, and fluctuations in incident X-ray intensity as deviations from one point on the curve, so that fluctuations in the accuracy of setting the incident angle and those in excitation X-ray intensity can be controlled separately.

Title: Crude refuse treating device
Inventor: ABE TAKEO
IPC: B09B3/00
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to execute ashing simultaneously with complete drying of crude refuse by pulverizing the crude refuse to be charged, housing the pulverized product into a treating vessel having vacuum pressure resistance and generating plasma under vacuum. SOLUTION: When the crude refuse is charged into the treating vessel 2 and a motor 10 is driven, a cutter 9 rotates to finely cut the crude refuse. The output of the cutter 9 is dropped after the fine cutting and, while the device is kept running, a microwave generator 21 is operated to irradiate the crude refuse with microwaves. At this time, the cutter 9 may be intermittently operated. When the drying of the work to be treated ends to some extent, the pressure is successively reduced to high vacuum and the plasma is generated in the treating vessel 2. The dried refuse is strongly oxidized and decomposed according to the generation of the plasma. Reactive gases are admitted by controlling the flow rate with a control valve 19 from a communicating path 18. The gases generated together with oxidation and decomposition are discharged by a vacuum pump.  As a result, the crude refuse is ashed exclusively of only the inorg. components.

Title: Method for executing rolling reduction to cast slab in continuous casting and apparatus therefor
Inventor: FUKUMOTO ICHIRO
IPC: B22D11/128
Filed: 1992-07-30
Abstract: PURPOSE:To surely prevent center segregation without developing internal crack by normally and reversely rotating eccentric roll pair and continuously executing ironing-rolling-reduction to a cast slab. CONSTITUTION:One pair or plural pairs of eccentric rolls 10 are vertically reciprocated in parallel with drawing line of the cast slab in the fixed range or the whole range of the rolling reduction zone A from solid-liquid two phase range to completing point W1 of the solidification on a drawing line of the cast slab. At the time of shifting the rolls 10 upward, the eccentric rolls 10 are rotated so that the eccentric quantity gradually reduces from the completing point W1 of the solidification toward the upstream side. On the contrary, at the time of shifting the rolls downward, the eccentric rolls 10 are reversely rotated so as to gradually increase toward the completing point W1 of the solidification. By this method, the rolling reduction while ironing is repeatedly and continuously executed to the part from the solid-liquid two phase range to the completing point W1 of the solidification in the cast slab W. In this result, without developing the internal crack in the cast slab W, the center segregation can surely be prevented.
