Inventor: OTAKA TADASHI
IPC: H01J37/244
Filed: 1989-03-30
Abstract: A scanning electron microscope for observing and measuring a minute pattern of a sample (2) comprising an electron lens (1) for focusing an electron beam (4) from an electron source onto the sample (2), wherein the electron beam (4) scans on the sample (2), an inclining means for inclining the sample (2) at an arbitrary angle α, and two secondary electron detectors (3a, 3b) disposed at positions which are respectively turned at the same angle ϑ around the central axis of the electron beam (4) from a plane which contains the axis of inclination of the sample (2) and the central axis of the electron beam (4). 
     As it is possible to measure the length of the minute pattern by detecting the secondary electron signal (5a, 5b) having a symmetrical wave-form while observing the minute pat­tern at the arbitrary angle, high measuring accuracy is at­tained.

Abstract: A hydraulic control device (10) for controlling a motor independently of the load pressure is proposed, which can be converted inexpensively to different pump systems. As manometric balance, the control device (10) has a two-way throttle valve (26) with a run-on circuit (24, 25) in whose cross connection (35) to the return side (23, 33) hydraulic blocking means (36) are arranged which, in the blocking position, block the function of the manometric balance. The control device (10) is suitable for controlling hydraulic functions on mobile machines which are supplied with pressure medium by tractors having different pressure medium supply systems such as a fixed displacement pump (12) or a variable displacement pump (45). <IMAGE>

IPC: G01R35/00
Filed: 1989-03-20
Abstract: A system is disclosed for calibrating vector corrected electrical measurements to adjust for distor­tion due to reactance in the measuring circuit, partic­ularly that caused by variable positioning of a circuit element, such as a probe or coupling. Initial error factors for directivity, source match, and frequency response, respectively, normally calculated from assumed reflection coefficients of respective primary impedance standards, are adjusted to correct for such reactance. Reflection coefficient measurements (magni­tude and phase) of a further impedance standard, dif­ferent from the primary standards, are obtained at multiple frequencies and corrected by the initial error factors. The corrected magnitude and phase measure­ments of the further impedance standard are compared with theoretical magnitude and phase values which vary linearly with frequency, and the initial error factors are adjusted so as to minimize any deviation of the corrected measurements from the linear values. There­after, by positioning the probe or other circuit ele­ment relative to a device under test substantially identically to its previous placement relative to the further impedance standard, the adjusted error factors can be used to obtain corrected measurements with minimized magnitude and phase errors due to reactance.

Abstract: The construction and manufacturing technique for a functional biocompatible intervertebral disc spacer is described. This device is useful for a replacement for a degenerated disc in certain treatments of back pain and spinal disease. The disc spacer possesses mechanical properties akin to those of the normal disc and will preserve normal functions of the spinal motion segment. The device achieves the desired properties by providing reinforcing fibers of appropriate orientation and number within an elastomeric matrix.

Abstract: A guided vehicle (2,3) determines its position relative to a number of uniquely-coded reflector boards (13) by scanning the boards with a rotating laser beam (14,15). In order to determine the position of a load (18) which is to be picked up by the vehicle, the laser beam scans three plain vertical retroreflective strips (19,20,21) which are affixed to the load at accurately known spacings. The position of the load is calculated from these spacings and from angles measured by the laser system. The calculations are continuously updated as the vehicle moves.

Abstract: The method determines the organic material content of sediments from data recorded in a borehole by at least two logging probes measuring different parameters. 
<??>The two probes are so chosen that one responds to a variation in the water content and the organic material content of rocks in the same direction while the other responds in a very different way to a variation in one or the other of these two constituents. They are also both chosen so that the lines I of constant content of organic material in a diagram with three end-members lie roughly on top of each other when the third end-member is either the water end-member PE or the clay end-member PA. The position of the line I(0%) is determined experimentally and, from this, the content of organic material corresponding to each pair of values of the parameters measured in the borehole is deduced. In a diagram in which the parameters used depend, for example, on the transit time  DELTA T of sound in the rock or on the electrical resistivity Rt of the formations, the lines of constant content form a family of parallel lines. 
<??>Application to the study of sedimentary basins.

Abstract: Method suitable for stopping a stepping motor, in particular in the event of an anomaly. A central control and calculating unit (26) continuously measures the stepwise chopping frequency of the current in each of the inductors (6, 7). In the event of an anomaly, the program for generating the periodic control signals is disconnected, that for chopping being maintained. The chopping frequency then oscillates on either side of a threshold (S) of normal operation. In each semi- interval (T/2) between two successive crossings of this threshold, the inductor current is inverted in the corresponding phase (6 or 7), which brakes the motor and stops it after a few cycles. <IMAGE>

Abstract: An active component with high chemical stability was identified and purified from resin of plant G.M.D. The resulting product has been extensively studied for its pharmacological and toxicological activities. Data indicated that the active component functions as a very potent cytolytic chemical compound. Cells were irreversibly killed at very low concentration less than 10ng per ml. With such low concentration, there was however, very little evidence of intoxication. In this report, we have invented various rapid methods for extracting the active component GMD 1630 in large quantity and way of long term storage. Also, in vitro bioassays and in vivo tests for monitoring intoxication were designed.

Abstract: A first light (160) is moved and illuminated by an x-y plotter mechanism on a rear projection screen (120) under computer control (400) so as to be continuously fixated by an eye of a test subject (300). The computer (400) also causes one or ones of fixed position second light (150), typically sixteen in number positioned in a regular array, to momentarily illuminate at various times corresponding to various positions of the moving first light. The test subject (300) indicates detection or non-detection of the momentary illuminations to the computer (400) by voicing the numbers ''1'', ''2'', ''3'', etc. From successive illuminations and test subject (300) responses the computer (400) is able to survey the entire visual field of each subject's eye in all directions. The surveyed visual field is plotted on graph paper with the same x-y plotter mechanism that is otherwise and at other times used for moving the first light source (160).

Abstract: A glass body is described, in particular a pane of glass, which is made in such a way that it is suitable for sealing to another material. 
<??>At the time of sealing, there is on the glass body at least one profile of an adhesive, which at this time is already solidified and consequently serves as a spacer. Furthermore, there is on the glass body a profile of a second adhesive, which at the time of sealing is still plastically deformable and has adhesive properties. During the establishing of the adhesive bond, this second adhesive is shaped and pressed onto the other material. Due to the fact that the profile of the second, still tacky adhesive is still directly on the glass body, or at least a layer of a material which does not transmit ultraviolet light, or possibly an intermediate layer of an adhesion promoter, a very good firm bond is achieved.
