An objective is to achieve a positional change measurement device which measures positional change of a dynamic measured surface by using speckle patterns while easily reducing influence of fluctuations in a measurement environment temperature. Provided is a positional change measurement device including: a light source; an illuminating optical system configured to guide light from the light source to a measured surface; an imaging optical system; an image pickup device configured to acquire a speckle pattern by receiving reflection light from the measured surface via the imaging optical system; and detected-length compensation means for compensating for fluctuations in a detected length caused by temperature fluctuations. Positional change of the measured surface is measured based on a result of cross-correlation computation performed on multiple speckle patterns acquired at predetermined time intervals.

The present invention provides an OOB detection circuit capable of making accurate signal determination even in the case where a characteristic fluctuation occurs in an analog circuit, thereby preventing deterioration in the yield of a product. To an amplitude determining circuit, a characteristic adjustment register for changing setting of an amplitude threshold adjustment mechanism for distinguishing a burst and a squelch from each other provided for the amplitude determining circuit is coupled. The characteristic adjustment register is controlled by a self determination circuit. An output of the amplitude determination circuit is supplied to a time determining circuit and also to the self determination circuit. On the basis of the output of the amplitude determining circuit, the self determination circuit controls the characteristic adjustment register.

A magnesium alloy sheet having an adequate strength and an excellent bendability is provided along with a method of manufacturing such an alloy sheet. The method comprises, rolling a magnesium alloy sheet through a reduction roll, the alloy thereof containing about 0.1-10.0 mass % of Al and about 0.1-4.0 mass % of Zn, wherein the magnesium alloy sheet has a surface temperature of about 100° C. or below at the time just before it is fed in the reduction roll, and the reduction roll has a surface temperature in the range of about 100° C. to 300° C. Particularly, when executing multipass rolling, at least the last pass is accomplished in non-preheat rolling wherein the magnesium alloy sheet and the reduction roll have specified surface temperatures, respectively.

When the number of rotations of a drive motor (3) driving a hydraulic pump (2) is variably controlled and thus each operation process in a molding cycle is controlled, as the hydraulic pump (2), a hydraulic pump (2) that can set at least a high fixed discharge flow rate (Qm) and a low fixed discharge flow rate (Qs) lower than the high flow rate is used, limit conditions for a threshold for the load condition of the drive motor (3) are preset and, during a molding operation, by setting a predetermined operation process at the high fixed discharge flow rate (Qm), the operation process is controlled and, when the load condition of the drive motor (3) is monitored and the load condition reaches the limit conditions, the flow rate is switched to the low fixed discharge flow rate (Qs) to control the predetermined operation process.

An electrostatic plotter or similar color image forming apparatus for forming an image on a recording medium, e.g. a paper web being transported under tension by a transport roller pair by a head while sensing a register mark formed on the medium. The distance between the register mark and a register mark sensor and the distance between the paper web and the head are maintained constant.

A color image forming apparatus of the type recording a register mark on a recording medium for registering the leading edges of images of respective colors to form a color image. The apparatus forms the register mark on the medium outside of the effective area of a main image and such that the mark extends perpendicular to an intended direction of medium feed. The register mark is developed in cyan and in the highest density to insure accurate register of colors. The register mark is cut off together with the leading edge of the medium.

A copier capable of binding copy papers at their center or their edge as desired. A bookbinding device is operatively connected to a paper outlet of the copier. To bind the papers at their center, a folding mechanism of the bookbinding device is activated first in order to form a crease along the center of each copy paper. Then, a binding mechanism of the bookbinding device is activated to sequentially stack the papers in an upwardly convex form and such that the creases face upward in alignment and, then, stich the papers together along the aligned creases by means of a stapler or the like. The bound papers are discharged to a stacking mechanism of the bookbinding device in a developed position so as to be stacked there while being folded double in the creases.
