摘要： In a time period from the time point where the forward end of a paper sheet fed from a pair of paper separation rollers reaches a registration roller to the time point where the registration roller is driven, when the load torque exerted on a forward roller is not less than second regulated torque, the transmission of power to the forward roller is released by a torque limiter provided for the forward roller. In this case, therefore, the force of paper feeding produced by the pair of paper separation rollers is regulated. Consequently, a suitable force of paper feeding can be applied to the paper sheet, thereby to make it possible to regulate the paper sheet straight in the direction of paper feeding as well as to prevent the paper sheet from continuing to be fed even if the amount of deflection of the paper sheet is saturated between the pair of paper separation rollers and the registration roller to prevent the paper sheet from being wrinkled.

摘要： A method and apparatus disclosed by this invention allows determination of the interstitial oxygen concentration in a silicon single crystal to be effected stably and accurately without being appreciably affected by change of the temperature of a sample under test. The interstitial oxygen concentration in the silicon single crystal is determined on the basis of the value of:(Light absorption coefficient).times.[1+a.times.(peak half width)]or the value of:(Light absorption coefficient).times.[1+b.times.(peak area)/ (peak height)](wherein a or b stands for a parameter whose value depends on the conditions for determination or the apparatus for determination and should be empirically fixed with respect to specific conditions of determination or the apparatus used therefor) concerning an interstitial oxygen absorption peak at 1106 cm.sup.-1 obtained by means of an infrared spectrophotometer.

摘要： A sheet feeder includes a feeder for feeding a sheet, a cassette for containing a plurality of stacks of small sized sheets side by side therein, the cassette including a plurality of biasing members for biasing the respective stacks of small sized sheets upwards so as to bring uppermost sheets of the respective stacks into contact with the feeder, a plurality of sheet detectors arranged in positions corresponding to the respective stacks of sheets for detecting the height of the respective stacks of sheets contained in the cassette, and a controller responsive to the plurality of sheet detectors for determining the absence of sheet in the cassette when at least one of the plurality of sheet detectors detects that the height of the stack has become lower than a predetermined height, and stopping a sheet feeding operation. This sheet feeder prevents the transfer device of an image forming apparatus from being smeared due to the fact that the small sized sheet is fed from only one stack.

摘要： A head for an ink-jet printer includes an elastic plate, a wall member defining an ink chamber together with the elastic plate, a nozzle provided in the wall member and communicated with the chamber, and a piezoelectric element. The piezoelectric element is shaped in a plate, has a side face, which defines a thickness of the piezoelectric element, and is disposed such that the side face faces the elastic plate. The piezoelectric element presses the elastic plate at the side face by an expansion due to a piezoelectric effect in a direction toward the side face. The head further includes electrodes attached to the piezoelectric element for applying an electric voltage across the piezoelectric element so as to cause the piezoelectric effect.
