Abstract: A method and apparatus for the micro-analysis of a surface (2) of a sample (1) wherein a mass analyser (12) is used to analyse secondary ions (17) emitted from the surface in response to the impact of primary radiation (20). The method comprises: extracting the secondary ions (17) in an electric extraction field maintained by applying an extraction potential difference between the sample (1) and an extraction means (3), and also maintaining an accelerating potential difference between the sample (1) and the mass analyser (12) thereby increasing the kinetic energy of the secondary ions (17) to be substantially equal to the energy required for analysis in the mass analyser (12); the extraction potential difference being less than the accelerating potential difference. In this way the extraction field can be controlled independently of the accelerating potential between the sample and the mass analyser (12).

Abstract: A two component type polyurethane adhesive is provided for fiberglass reinforced plastics which re­quires no cleaning, preparation or treatment of the surface, and the like. The curative component is a nitrogen-free liquid polyether or polyester in an amount such that in association with a urethane prepolymer component containing free NCO groups, the ratio of the free NCO groups in the prepolymer component to the OH groups in said curative component is at least 1.2 and desirably at least 1.35. Such high NCO/OH ratios have unexpectedly been found to provide good adhesion and especially good humidity adhesion and peel strength adhesion to fiberglass reinforced plastics or metal surfaces which are free from any surface treatment.

Abstract: A method of manufacturing a superconductor by applying a floating zone method to a raw material sintered ingot. This method is adaptcd to obtain an elongated superconductor which can provide high critical current density. A floating zone is moved along the raw material sintered ingot with such speed difference that the speed in its forward end portion is higher than that in its rear end portion, thereby to obtain a superconductor having a smaller diameter. In order to attain a higher crystal orientation property, it is preferable to select the product of the diameter (D mm) of a superconductor provided with a crystal orientation property, which is produced after passage of the floating zone, and the speed (V mm/h) for moving the floating zone in a range of 0.5 ≦ DV ≦ 20 and to select pressure P of an atmosphere encircling the floating zone in a range of 0 < P ≦ 29,43 [N/cm²] (0 < P ≦ 3 [kgf/cm²]) as well as to pass the floating zone along the raw material sintered ingot at least twice.

The viewer is thus provided with an overview of the currently transmitted programme choice arranged in the form of several small pictures shown next to one another or underneath one another and can switch the receiving set to a desired programme. A novel arrangement is intended to provide the possibility of easily associating each small picture with the associated signal source. For this purpose, an identification is stored in digital form for each signal source in a non-volatile memory. During the simultaneous display of several small pictures, the associated identifications are read out and displayed in a non-overlapping manner with the respective picture on the screen.

In the case of the other dopants, the resulting aluminum nitride can be sintered without the use of additional sintering aids.

Abstract: With the method for producing EPROMs based on self-­alignment using a gate electrode as the mask for impurity ion doping, when selectively removing an oxide film between the control gate electrode and the floating gate electrode, the side surface of control gate electrode can be formed flat without projected and recessed areas by removing a thin film deposited at random on the side surface of the upper control gate electrode. Thus, the desired channel region width can be formed, even when impurity ions are doped, with the gate electrode used as the self-alignment mask. Controllability of EPROM production can, therefore, be remarkably improved.

Abstract: The present invention is directed to the manufacture of polyetherimide resin reinforced laminates where their production is via conventional prepreg processing techniques. Broadly, then, the present invention is directed to a method for making a reinforced prepreg of polyetherimide-forming resin. The method comprises forming a solvent solution of a polyetheramide acid and immersing a web of reinforcement in said solution. The immersed web then is withdrawn and heated to evaporate the solvent and form the prepreg. Complete conversion ofthe polyamic acid to polyetherimide may be effected in a treater oven capable of maintaining a suitably high temperature required for the particular polyamic acid used (e.g. around 300° C); otherwise pre-conditioning the prepreg in a separate heating unit is desirable. Thereafter, the prepreg can be laminated to metal foil, optionally with additional prepregs. The laminate is formed by heating said prepreg and metal foil under pressure for a time adequate to bond the foil.

Abstract: Apparatus for a bipolar active semiconductor magnetic field sensor (300) that has a higher sensitivity than semiconductor field sensors presently existing in the art. Specifically, the inventive sensor (300) utilizes a semiconductor structure containing a single emitter layer (310), a single base layer (320) that is overlaid over the emitter layer (310) and two separate oppositely situated collectors (333,337) located above the base layer (320). A bias lateral majority carrier flow (530,540) is established, in preferably and respectively both the base and emitter layers (electrons in the emitter, holes in the base), that flows in opposite directions in these layers and is oriented normal (transverse) both to the direction of transistor current and to the direction of a magnetic field (550) that is to be detected. When the magnetic field (550) is applied to the sensor, this field imparts a Lorentz force to these carriers which causes these majority carriers to deflect in the same direction (510,520) in both the emitter and base layers, respectively. The resulting deflection of these carriers, in turn, produces local Hall effect voltages, that are proportional to the strength of the magnetic field, across the emitter-base junction that locally increases the forward bias of this junction near one collector and locally decreases the forward bias of this junction near the other collector so as to exponentially increase the collector current (Ic) flowing through one collector while exponentially decreasing the collector current flow through the other collector. Inasmuch as the exponential collector current flow is a very sensitive function of emitter-base voltage, the inventive sensor is substantially more sensitive than semiconductor sensors known in the art.
