A longitudinal profile measuring apparatus including a relative distance meter located on a frame supported by more than two wheels in a row in a direction of a measuring line for measuring relative distance to a target surface, a moving distance meter for measuring moving distance of movement along the measuring line on the target surface, and a data processing unit for finding spatial data, which shows a rough profile of the target surface, along the measuring line from the relative distance measured by the relative distance meter. The data processing unit storing moving distance data associated with relative distance data to the target surface and transforming the relative distance data of the stored data into amplitude corresponding to frequency, multiplying the amplitude corresponding to frequency by a coefficient of correction for allowing the apparatus to have a gain with a desired frequency characteristic for correction, and inverse transforming the corrected amplitude to find the corrected spatial data of the target surface.

A slotted waveguide antenna assembly includes a slotted waveguide, a dielectric beam shaper and reflectors which are fixed and held by a holder member. The dielectric beam shaper is formed from a pair of dielectric plate members. The dielectric plate members are so arranged that they are slightly closer at the forward ends than the base ends, thus providing a nonparallel arrangement. The inclination of the dielectric plate members is selected within a range of 0.8.ltoreq.d/D&lt;1 (D: a distance between the dielectric plate members at the base portions, d: a distance between the dielectric plate members at the forward portions). The dielectric plate members have a thickness which produces a phase difference, between electromagnetic waves reflected by inner surfaces of the respectivie dielectric plate members that are opposite each other. The electromagnetic waves reflected by interfaces at external surfaces of the respective dielectric plate members move towards the space between the dielectric plate members, and substantially cancel each other because of the phase difference.

Slotted waveguide antenna assembly

The present invention is applied to a slotted waveguide antenna assembly which comprises a slotted waveguide having a plurality of slots, a reflector having an aperture in front of the slotted waveguide and reflecting radiated electromagnetic wave for forming directive beam, and a mounting portion for mounting the antenna assembly onto a place where the antenna assembly is to be installed. In such an antenna assembly, a fixing member is provided on the reflector at a position spaced from the slotted waveguide. The fixing member extends between the opposite walls of the reflector and fixed thereto. The fixing member has an end which projects outwardly from the wall of the reflector to form the mounting portion. The fixing member is sufficiently thin as compared with the working wavelength. The slotted waveguide antenna assembly may have a dielectric wave-guiding arrangement.

A back-reflection type light diffusing apparatus of this invention is suitable for use in liquid crystal display panels or the like, and is formed by a light guiding plate. The light guiding plate has one surface which forms a first surface through which light is radiated while its opposite surface forms a second surface on which a light reflecting plate is mounted. The light reflecting plate is provided with non-reflecting portions disposed in such a manner that the area thereof increases the closer it gets to the light source so as to radiate light from the light radiating surface uniformly over its entire area.

There is provided a calculator for calculating check digits which are obtained from code numbers according to a modulus 10, modulus 11 or the like check. In accordance with one embodiment of the invention, the desired check digit original numerals are indicated in response to the determination of a code number and weights and the desired check digit is readily obtained from the sum of the check digit original numerals. In accordance with another embodiment, the desired check digit is directly indicated in response to the setting of a code number. In accordance with still another improved embodiment, the desired check digit according to the modulus 10 and that according to the modulus 11 are selectively indicated in response to the setting of a code number.

A calculator for calculating check digits which are obtained from code numbers according to a modulus 10, modulus 11 or similar check. In accordance with one embodiment of the invention, the desired check digit original numerals are indicated in response to the determination of a code number and weights and the desired check digit is readily obtained from the sum of the check digit original numerals. In accordance with another embodiment, the desired check digit is directly indicated in response to the setting of a code number. In accordance with still another improved embodiment, the desired check digit according to the modulus 10 and that according to the modulus 11 are selectively indicated in response to the setting of a code number.

There is disclosed a numbering machine designed so that code numbers as well as check digits each consisting of a single-place digit are printed by means of a mechanical mechanism. The check digits are printed by a check digit type wheel having an arrangement of circulating digits which are calculated in correspondance with code numbers in accordance with a modulus 10 or 11 check with predetermined weights. When there is a carry from one code number digit place to the next higher digit place, it is necessary to print the digit skipped a predetermined number of the digits in the circulating digit arrangement, and as a result a drive control mechanism is provided so that when a change from one code number to the next higher code number necessitates a skipping operation, the change is detected and the check digit type wheel is rotated idly through a predetermined angle.
