Title: Dynamisch einmodiger Halbleiterlaser
Inventor: KEIL RUDOLF DR
IPC: H01S5/14
Filed: 1986-09-02
Abstract: Es wird ein dynamisch einmodiger Halbleiterlaser be­schrieben, der aus einer Laserdiode (1) mit angekoppel­tem externem Resonator besteht. Der Resonator weist einen gegenüber einer Lichtaustrittsfläche (12) der Diode (1) angeordneten Resonatorspiegel (2) und eine zwischen der Diode (1) und dem Resonatorspiegel angeord­nete Kollimationsoptik auf. Ein bekannter derartiger Laser läßt sich mit der gewünschten Resonatorlänge oft­mals nicht oder nur sehr schwer herstellen. Es soll da­her ein derartiger Laser angegeben werden, der relativ einfach und mit der gewünschten Resonatorlänge herstell­bar ist. Dies wird erreicht, wenn die Kollimationsoptik aus einer brechenden hemisphärischen und mit ihrer Flachseite (31) auf den Resonatorspiegel (2) aufgebrach­ten Mikrolinse (3) besteht. Diese Linse kann einfach durch Aufschmelzen eines kleinen Glastropfens auf den Resonatorspiegel hergestellt werden.

Abstract: This invention concerns a transparent sheet containing a directional image and method for forming such a sheet. A directional image is created in a transparent sheet comprising a monolayer of microlenses by forming deformations or axial markings in at least some of the microlenses by irradiation with a laser beam. The sheet may further comprise a partially light transmissive mirror disposed behind at least some of the microlenses. The directional images may be formed in transparent sheet which has been applied to a document as an overlay. When viewed under diffuse lighting conditions, the deformations appear as a dark image. The deformations may be formed so that when viewed under retroreflective conditions within a conical field the image is darker than the surrounding background, and when viewed under retroreflective conditions outside the conical field the image is brighter than the surrounding background.

Abstract: A diamond cutting tooth (26, 28, 30) (= A) for use in a petroleum drag bit (10) is provided with an extended and expanded effective diamond cutting surface by providing a linear sequence of triangular prismatic, synthetic, polycrystalline, diamond cutting elements (32, 36, 38, 40) generally along the line of direction of cutting within each tooth (A). Each element (36, 38, 40) is offset from the preceding element in the sequence in a direction nonparallel to the line of cutting. More particularly, equilateral triangular prismatic diamond elements (36, 38, 40) are laid within a V-shaped groove (44a, 44b) within a mold (42) from which the cutting tooth (A) is molded through conventional infiltration matrix techniques. The apical opening of the groove (44a, 44b) is 70 degrees, wheras the apical extent of each of the triangular apexes is 60 degrees. Each triangular element (36, 38, 40) is laid on one side or other of the longitudinal groove (44a, 44b). Matrix metal or binder is filled in the groove (44a, 44b) between the diamond elements (36, 38, 40) thus forming a diamond cutting tooth (A) having an effective apical dihedral angle of 70 degrees while using only 60-degree triangular prismatic elements (36, 38, 40). Worn triangular prismatic elements (36, 38, 40) can be particularly adapted to this tooth structure by orienting at least one worn portion of each triangular element (36, 38, 40) oriented toward the interior of the tooth (A) with the remaining unworn point or points disposed nearest the exterior of the cutting tooth (A).

Abstract: In order, for example, to expand the input and output of a microcomputer (7) having a serial input/output capability, a parallel data input port (2 or 3) or output port (4 or 5) is selected by clocking serial selection bits from a serial data line (1) into a first shift register (56) and then enabling a latch (58) for the register parallel output (57). This results in a change in level on a particular one of a set of a parallel output line (35,36,49,50) which corresponds to the particular group of selection bits written, and hence to a particular port. If the selected port is an output port the change in level results in the strobing of a latch (43 or 44) corresponding to that port, and hence to the transfer of the contents of a further shift register (39 or 40) corresponding to that port. These contents are previously written in from the serial data path (1), each further shift register (39,40) being connected in cascade with the first register. If the selected port is an input port the change in level results in the enabling of a gate (31 or 32) corresponding to that port, and hence to the transfer of the port information to a shift register (27 or 28) corresponding to that port, whence it is subsequently clocked out to the serial data path via a respective transistor (25 or 26).

Abstract: In known connecting arrangements for erecting scaffoldings, a wedge must be inserted in the support provided on a horizontal column in order to attach the horizontal beams of the scaffolding. For this reason, two people are required to put up and take down scaffolding. The new connecting arrangement for erecting scaffoldings is to enable scaffolding to be put up and taken down by only one person. In the new connecting arrangement, the support is constructed in the shape of a dish with a peripheral raised edge, against the inner side of which the wedge can be laid. The head of the beam contains a nose, by which the beam in question is to be attached to the edge of the support. This new connecting arrangement ensures that the horizontal beam is situated approximately in the horizontal position even when it is only attached by one end. Consequently, it is possible, when putting up the scaffolding, for one person first to attach the beam to the support and then to fix the wedge in position. <IMAGE>

Abstract: The invention relates to a process for preparing cationic paint binders based on polyether urethanes formed by selective reaction of an NCO group of diisocyanates which contain NCO groups of different reactivities with the primary hydroxyl groups of a polyhydroxypolyether using 1,4-diazabicyclo-[2.2.2]octane (DABCO) as catalyst and subsequent reaction of the left-over NCO groups with a secondary amine. The process substantially avoids the formation of low molecular weight basic by-products. The binders are used for formulating paints which become water-thinnable on protonation, in particular cathodically depositable electropaints.
