Abstract: A fuel injection nozzle is proposed which opens toward the outside and functions with a valve needle and two springs, and further wherein a throttle restriction is effective after a first portion of the opening stroke, acting as a pre-stroke, and can be subsequently rendered ineffective. The two springs having a predetermined certain relationship to one another enable an abrupt increase in closing force after the pre-stroke. The first spring, embodied as a compression spring, acts in the closing direction; the second spring, having a smaller force than the first spring and acting counter to the closing direction, is rendered ineffective after the pre-stroke has been performed.

Abstract: The invention relates to semiconductor devices comprising a guard ring. The conventional processes for the manufacture of guard rings, by localised diffusion through windows in a thick mask, give rise to a superficial contamination of the crystal and to crystal perturbations. The process according to the invention consists in depositing first of all on the crystal a diffusion source (44), limited to the location of the future guard ring (43), and then in carrying out the diffusion. The junctions formed in this manner are reliable and free from noise. Application to diodes and transistors. <IMAGE>

Abstract: A sailing craft (1) comprising a center cross-plane symmetric hull (2,3) and capable of sailing in either direction is disclosed herein. Good skimming properties are imparted to the sailing craft (1) by utilizing the principle of the normative angle of inclination based on the stability and the effectiveness of the sail and keel function of the craft, this being realized by designing the bottom side of the hull (1) as a substantially flat plane enclosing an angle of from 10 DEG  to 20 DEG  with respect to the plane of the water line and providing relatively deep draught keel-rudder (821,101) which are equidistant with respect to the center cross-plane and preferably a sail (10) which is isosceles in outline for having a relatively low point of pressure. Boom attachments (25,26) edging strainers (30) and an automatic trimming system may keep the sail (10) in the ideal profile thereof while balancing the pressure point and the lateral point.

Abstract: When two sheets of slack material, for example the two sides of a paper or plastics bag, are to be separated by means of a pointed tool, problems arise because the two sheets can easily bend over, both in the same direction. If moreover these sheets are formed from smooth material, they also adhere together by vacuum sealing or by electros- tatical forces. The solution for these problems is to enclose said sheets (17a, b) into a positioning block (10a, b) in which a hollow space is recessed or saved for receiving the volume of the pointed tool (19) to be driven thereinbetween. This driving-in of the pointed tool can be combined with the issuance of pressurized air between the sheets. To this end the pointed tool is provided with grooves for guiding said pressurized air or with a separate blow-pipe (18) slidable over the pointed tool.
