Abstract: A character erasable printing apparatus is designed to erase a character or an underline in plural times of erasing action by inching the printing head, and to print a character by a single printing action. 
     Therefore, when an underlined character is erased together with its underline, and a correct character is printed together with an underline, the underline is interrupted. 
     Disclosed are, to prevent such interruption of the underline, a character erasable printing apparatus cap- able of erasing only the character without erasing the underline when the underline mode is being set, a char­acter erasable printing apparatus capable of erasing only the character without erasing the underline when erasing a character erasable printing apparatus capable of erasing the underline without inching the printing head when erasing an underline of a character adjacent to an under­lined character.

Abstract: A gas laser, particularly an HeNe laser in a laser transition, whose upper level is the 3s2 level, tends to be excited to produce a relatively long wavelength laser emission, in the case of the HeNe laser having a wavelength of 3.39  mu m. According to the invention, in order to suppress this emission, the length-related cross-section of the capillary (1) is larger than the associated beam diameter (d) of the Gaussian beam (3) of the desired laser line and is at least approximately proportional thereto, and the diameter (D) of the capillary is smaller than the diameter (d) of the Gaussian beam (4) of the long wavelength emission.

Abstract: Image coding system where document retrieval and printing are compatible, comprises first step of dividing a first image into n x n meshes, second processing step of performing resolution conversion of the divided n x n meshes into one dot and obtaining a second image, third processing step of obtaining first data from the first image excluding all white meshes, and final processing step of decoding the first image from the first data and second image. Since a part of code data of the coded image is also provided with image for retrieval, and the first, second, third and final processing steps are executed, document retrieval image decoding processing for a display device (low resolution device) most requiring high speed and image processing for an image printer requiring resolution rather than high speed are executed in hierarchy, thereby low quality image can be obtained from code data of high quality image. Consequently high compression coding of the high quality image utilized in printer output and the document retrieval at high speed by the low quality image utilizing the display device (low resolution) are compatible, and the low quality image can be utilized in document retrieval or the like at high speed without resolution conversion.

Abstract: An air-drop body (11) with a rear parachute stowage space (38), especially in the version of a homing-fuse submunition descending into the target area on the spin parachute, is to acquire a launch-proof connection, which can be made in a simple and space-saving way and which can be released in a functionally reliable manner, between the parachute cassette (16) and the operative part (24), in order to prevent transfers of force in the periphery of the cassette (16) or of the operative part (24) and, for a given calibre, to make it possible to obtain a large-volume parachute stowage space (38). For this, the parachute cassette (16) is centrally positioned, via its rear wall (17) terminating in a funnel-shaped manner in a central sleeve (22), in the centre of the rear wall (12) of the operative part by means of a connecting element which can burst open pyrotechnically in the plane of the parting seam (27) and which is preferably designed as an axially short pyrotechnic separating screw. This engages with its head (33) behind a rear-wall protuberance (23), against which the cassette-wall sleeve (22) is pressed axially by means of a flanged bush (36), into which the separating-screw threaded bolt (26) is screwed coaxially.

Abstract: A method for determining the density of a liquid using a falling needle viscometer wherein the viscometer (10) includes a vertical cylinder (12) which is filled with the liquid the density of which is to be determined. Using a funnel (24) at the top of the cylinder, a first needle (54) having a known density is allowed to fall through the liquid in the cylinder. The time taken for the needle to fall between two marks (22a,22b,22c,22d), or transducers, spaced on the cylinder a known distance apart is measured, from which the velocity of the needle through the liquid is calculated. Then a second needle having the same dimensions as the first and a known density different from that of the first needle is allowed to fall through the liquid. The time taken for the second needle to fall between the two marks on the cylinder or transducers is measured and the velocity of the second needle through the liquid is calculated. Using the densities of the two needles and the velocities of the needles through a Newtonian liquid the density of the liquid is calculated using disclosed equations. Using the densities of three needles and the velocities of the needles through a non-Newtonian liquid, the density of the liquid can be calculated using disclosed equations.

Abstract: A numerically controlled machine tool (1), such as a grinding machine, is capable of machining a workpiece with a precise dimension by measuring a workpiece machining dimension and/or a tool length. According to one aspect of the invention, when the machining operation is provisionally terminated, a machining dimension of the workpiece (9) is measured without dismounting the workpiece (9) from a table. If a machining error is detected, the workpiece is further machined to a target dimension to thus eliminate the machining error. According to another aspect of the invention, the grinding surface of a grinder is subjected to dressing or truing, and the length of the grinder reduced through the dressing or truing is detected to determine the actual length of the grinder. With the known length of the grinder, the feeding amount of the grinder with respect to the workpiece is set for the subsequent machining operation.
