A shape measurement apparatus of this invention includes (i) an optical distance measuring device which measures the distance to the point to be measured on the object to be measured, (ii) a position setting/changing mechanism which sets and changes the relative positional relationship between the object to be measured and the optical distance measuring device, and can set, for each point to be measured, a plurality of different angles including .alpha. and -.alpha. (0.degree..ltoreq..alpha..ltoreq.90.degree.) in an identical plane as the tilt angle of the surface of the object to be measured with respect to a plane perpendicular to the optical axis of the optical distance measuring device, (iii) a position detection mechanism for detecting the relative position between the optical distance measuring device and the point to be measured, and (iv) a shape data forming unit for forming shape data of the object to be measured on the basis of position data and distance data which respectively represent the relative position and the distance between the point to be measured and the optical distance measuring device. This arrangement can reduce measurement errors caused by the irradiation angle of the measurement light from the optical distance measuring device to the object to be measured.

Shape measurement apparatus and method

A three-dimensional form measuring apparatus of the present invention comprises (i) an optical distance measuring equipment for irradiating an object to be measured with slit-like irradiation light and for receiving, on a two-dimensional light receiving sensor, reflected light from the object; (ii) a position setting mechanism for setting a relative positional relationship between the optical distance measuring equipment and the object; (iii) a signal selecting section which detects whether or not the width and maximum luminance of an optical image reflected by the object are within a predetermined range and thereby selects, as an output signal for preparing data, an output signal of the two-dimensional light receiving sensor concerning the relative positional relationship between the optical distance measuring equipment and the object set by the position setting mechanism; and (iv) a form data preparing section which prepares a three-dimensional form data of the object based on the output signal of the two-dimensional light receiving sensor selected by the signal selecting section. Accordingly, errors in measurement caused by the inclination of the measuring surface are reduced, whereby the three-dimensional form of the object can be stably measured with a high accuracy.

A pair of stations are associated with each other so that a data frame is transmittable from either to the other, the data frame including as basic fields thereof a header field, a data field with a data sequence, and a frame check field. The former comprises a calculator for calculating a total length of the basic fields, as a basic length, and/or for calculating a current error rate, a controller depending on the basic length and/or the current error rate to make either of an affirmative decision for and a negative decision against sending a request for an acknowledgment of a reception of an entire length of the data frame by the latter, and a formatter for formatting the data sequence into the data frame, the formatter being responsive to the affirmative decision to combine the basic fields and a message field containing the request, to constitute the data frame.

The invention is directed to a focusing optical system for semiconductor lasers, which is regulated in terms of magnification power in both its directions normal to the optical axis, so that the back focus of sufficient magnitude can be made equal in both the directions and the magnitude of aberration can be regulated to achieve an improvement in focusing efficiency, and in which a light beam from a semiconductor laser having varying exit angles in the horizontal and vertical directions is focused on a spot having substantially equal diameters in the horizontal and vertical directions. This focusing optical system comprises first lens unit L1 including a rotation asymmetric lens having positive power in the direction defined by a large exit angle at which a laser beam emanates from the laser, a second lens unit L2 including at least one lens of negative power, and a third lens unit L3 that is a rotation asymmetric lens unit having positive power in the directions defined by both large and small exit angles.

In an image recording apparatus in which a pinch roller restrains lateral movement of image receiving paper, a skew feed roller and an edge guide are operative, by virtue of a curved portion of the paper feed path between the pinch roller and the skew roller, to position the paper laterally despite the restraint imposed by the pinch roller. The skew roller and the edge guide are disposed along a straight portion of the paper feed path.

A sliding/tilting sunroof structure whose overall height is kept relatively small by using an actuating linkage with sliding front and rear guides with a pivoting link extending from each guide to the sunroof panel. A rear portion of the front link is additionally guided by a front portion of the rear guide.

A rod in the form of a composite metal wire having a harder metal core surrounded by a softer metal cladding is introduced together with lubricant into a die comprising an approach which includes a first frustoconical opening defining a vertical angle between 0.degree. and 5.degree. (exclusive of 0.degree.) and a second frustoconical opening defining a vertical angle between 6.degree. and 20.degree.. The lubricant is pressurized in the first frustoconical opening of the die approach while the rod is drawn under fluid lubrication.
