Title: Centrifugal clutch
Inventor: WADA HIROSHI
IPC: F16D43/06
Filed: 1978-04-12
Abstract: PURPOSE: To change the number of rotation of a clutch according as the input, by means of setting up the second spring actuated by outside.  
     CONSTITUTION: A centrifugal clutch is in a separated condition of a drive plate 21 and a driven plate 26 by only the first clutch spring 27, but when a counter axis 3 may be rotated above a prescribed rotation number, because that the centrifugal forces acting on balls 22 are converted into the left displacing forces by guides 23, the centrifugal clutch is jointed by means of compressing both plates 21, 26. Now, for the necessity of large drive power as in climbing the slope, when a spring bearing 29 may be moved to the right by actuating the operation lever, the interval distance l1 becomes enlarged than the distance l2 by means of acting on a plate 21A by the energy force of the second clutch spring, and during the transition time from the first velocity to the second velocity, a large number of rotation due to the first fast running is obtained.

Title: Controlling circuit with control output sudden change preventive function
Inventor: HIRAYAMA YUTAKA
IPC: G05B17/02
Filed: 1986-02-28
Abstract: PURPOSE:To prevent a sudden change in a model output at the time of switching a parameter of a linear model, and to improve the control performance, by installing a variation rate limiter for limiting a variation rate of an input of an integrator, in front of the integrator of the final stage for constituting a part of the linear model. CONSTITUTION:A variation rate limiter 3 for limiting a variation rate of an input of an integrator 4 is installed in front of the integrator 4 of the final stage. Therefore, when the variation rate of the variation rate limiter 3 is set in advance to the maximum variation rate value within a range in which modeling can be executed correctly at the time of a regular operation of a process being a controlled system, a control output is not brought to a sudden change exceeding a variation rate by which the process can be varied, even at the time of switching of a parameter 5 or a parameter 6 of a linear model by a model switching deciding circuit 7. Accordingly, an abnormal sudden change of a model output is prevented, and an output of the model moves smoothly. In this regard, the variation rate limiter 3 applies a limit to a variation rate of an input of the interrator 4, and sets the variation rate in advance to the maximum variation rate value by which a correct model output can be obtained at the time of a regular operation of the process being the controlled system.

Abstract: PURPOSE: To prevent the double delivery of sheet materials by providing facing rollers having different coefficients of friction with sheet materials between the first and third rollers and controlling the driving timing of the first and second rollers by the detecting means for the sheet material provided in the vicinity of the second roller.  
     CONSTITUTION: When two sheets of paper are delivered doubly and the second rollers bit them, one sheet in contact with the roller 5a having a coefficient of friction greater than that of another proceeds first and the roller 5b having a smaller coefficient of friction comes to a stop. Accordingly, the sheets 2 are separated and only the paper on the side of the roller 5a is delivered to the rollers 7. At this time point, the paper forms a loop at just before the roller 7 not rotating and stand by. Then, the paper is delivered to the roller 7 which rotates in time synchronism with the drum 1. On the other hand, the remaining paper 2 within the rollers 5 is detected by a microswitch 6, and the driving first rollers 4 is temporarily stopped to be well timed therewith. in this manner, the double delivery of sheets of paper is strictly prevented.

Abstract: PURPOSE: To control the section intensity distribution of a laser beam to contrive to uniformize the crystal grain diameters of crystal grains in a semiconductor thin film when the semiconductor thin film is irradiated with the laser beam to crystallize the thin film. CONSTITUTION: A film-forming process is first performed and a semiconductor thin film 2 is formed on an insulating substrate 1.

Title: Catalytic combustion type exhaust gas treating apparatus
Inventor: MURACHI MIKIO
IPC: F23G7/07
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To lengthen a catalytic life by reducing poisoning of the catalyst even when untreated exhaust gas contains substance to become catalytic poison. SOLUTION: A catalytic poison adsorption filter 6 for adsorbing catalytic poison contained in untreated exhaust gas is formed at an upstream side of a catalytic layer 5. Since the filter 6 is formed by coating a carrier with active alumina, its surface area is extremely large, and adsorption efficiency of substance to become the poison is very high. And, since the alumina exhibits both acid and alkaline, even if any of the acid or alkaline substance is contained in the exhaust gas as the poison, it adsorbs it to neutralize it. Further, when alkali metal or alkali earth metal is carried thereon, its surface exhibits strong alkaline, and hence when the poison exhibiting strong acid of large quantity is contained, it adsorbs it to neutralize it, thereby effectively reducing the catalytic poisoning.

Filed: 1995-03-03
Abstract: PURPOSE: To prevent nonload printing even when the positioning between paper sheet length and FCB length (channel interval) or agreement of the printing start position of a sheet with a printing mechanism position is omitted.

IPC: H01L21/338
Filed: 1991-02-18
Abstract: PURPOSE: To avoid damage to a semiconductor device due to ion implantation and to realize shallow doping of N-type impurities to a III-V compound semiconductor substrate with good controllability by a method wherein silicon diffused in the III-V compound semiconductor substrate is made active by a process of thermooxidization simultaneously with diffusion. CONSTITUTION: A silicon layer 12 is formed and thereafter, the layer 12 and a cap layer are thermooxidized in the range of 500 to 1100 deg.C. By the thermooxidization of the silicon layer, silicon is diffused in a substrate 10 and the diffused region 14 is formed. In the step of this thermooxidization, the diffusion of the silicon extends to the interior of the III-V compound semiconductor substrate, which is the layer under the region 14, and at the same time, electrical activation of the diffused silicon is accelerated. During this process, gallium and arsenic are diffused to the interiors of the silicon and cap layers and the amount of the gallium and the arsenic is equal to the amount of silicon, which is diffused in a gallium arsenic, or is larger than the amount of silicon. Moreover, a small amount of O2 is diffused in the layer 12.  If oxygen is diffused in the silicon and cap layers, a very thin silicon dioxide layer can be formed on the surface of the cap layer.

IPC: G01N21/35
Filed: 1991-02-16
Abstract: PURPOSE:To make it possible to perform the quantitative analysis of samples to be measured in a broad concentration range with the intact state of the mechanical structure of an analyzer by selecting only the wave-number points having the linearity of absorbance in a concentration range wherein measurement can be performed among absorbing spectra, and computing the concentration of the component to be measured based on the absorbance value. CONSTITUTION:When the relatively low concentration of a compound having an absorbing spectrum is analyzed, a plurality of wave-number points used for concentration computation are selected among all wave-number points (a), (b) and (c). When the slightly higher concentration is analyzed, a plurality of the points used for the computation are selected among the points (b) and (c). When the more higher concentration is measured, a plurality of the points are adequately selected only in the point (c). It is not necessary to stick to the top of the absorption peak for the wave-number point used for the concentration computation. The concentration computation can be performed by selecting only selecting the base of the absorption peak and a part without absorption. The concentration range can be arbitrarily changed, and the result having the excellent linearity is obtained. The quantitative analysis of the samples in the broad range can be readily performed without changing the constitution of the analyzer.
