摘要： An electro-optical modulator has a monomode light waveguide modulator for which a pressure-sensitive signal generator is provided as a signal source for the purpose of modulating a light power signal supplied to the monomode light waveguide modulator over an input light waveguide, the electrical output of the signal generator being either directly or indirectly connected to an electrical input of the monomode light waveguide modulator. The arrangement serves for the transmission of signals representing pressure values, for example, acoustic pressure values, over an optical transmission system, and inasmuch as the electrical signals are generated by the pressure-sensitive signal generator, no external supply devices whatsoever are required at the modulator for the electrical energy.

摘要： A germanium body containing impurities therein, such as B or Al is provided with a layer of a gettering material such as pure Si or SiO.sub.2, along at least one surface of the body, a melt zone is generated about the so-coated body and passed a number of times from one end of the body to the other whereby the gettering material binds the impurities within the germanium body and complex-impurity compounds accumulate at the respective ends of the body. After a desired degree of purity is achieved, the melt zone is deenergized and the impurity-containing ends are severed from the remaining body portion and any excess gettering material is removed.

摘要： A device for the transmission of information pertaining to handwriting with a piece of equipment which records the x and y-coordinates of the location of the writing pen. The device transmits the coordinates of the writing information after a suitable delay and transmits the coordinates of the commencement point of a new item of writing without delay. In this way the output receives the coordinate information of the commencement point at a time prior to the receipt of information pertaining to the writing itself, thus permitting a lower speed printing device than would be required if the output printer received the new coordinates of a handwritten item substantially simultaneously with the commencement of the coordinate information of the writing.
摘要翻译： 用于记录与记录笔的位置的x和y坐标的一件设备相关的手写信息的装置。 设备在适当的延迟之后发送写入信息的坐标，并且不延迟地发送新的写入项目的开始点的坐标。 以这种方式，输出在接收到与书写本身相关的信息之前的时间接收开始点的坐标信息，因此如果输出打印机接收到手写的新坐标，则允许比所需的更低速度的打印设备 项目与写作的坐标信息的开始基本上同时进行。

摘要： For examining tissue samples that were taken from a tissue area with suspicion of tumor it is proposed that the tissue samples be examined shortly afterward for a measurement value typical of tissue alteration. With tissue samples taken spatially-systematically, a measurement value distribution at the sampling site can be ascertained, and an image of the tissue alteration before sampling can be represented. The device for performing the method includes a sampling device (PU), a supply device (TU), a detector (Det), an evaluation unit (CPU), a storage unit (SU) and an output device (AV) that allows an online examination of taken tissue samples (Pr), and with which the three-dimensional image can be represented by, for instance, a distribution at the sampling site of fluorescence achieved by means of systemically applied markers.

摘要： An electroluminescent semiconductor diode having a homogeneous monocrystalline semiconductor substrate providing a first zone on which an epitaxial layer has been formed providing a second zone. This second zone has a forbidden-band-width which changes steadily with increasing distance from the first zone. This second zone possesses a junction between a sub-zone having the properties of a "direct semiconductor" and a sub-zone having the properties of a so-called "indirect semiconductor" which lies parallel to the boundary between the first zone and the second zone and also parallel to the pn-junction of the diode. The pn-junction of the diode is located in the second zone and particularly in the sub-zone have the properties of an "indirect semiconductor" but at such a short distance from the junction of the two sub-zones that the major part of the charge carriers injected from the pn-junction in the direction towards the sub-zone having the properties of a direct semiconductor pass to this latter sub-zone.

摘要： An arrangement for coupling a light waveguide, such as a monomode glass fiber to a laser diode and a method of forming the coupling characterized by the laser diode being an integrated part of a semi-conductor chip having a mirrored step projecting out of a seating surface for the monomode glass fiber. The mirrored step defines an end face of the diode from which the laser beam emerges and the seating surface extends parallel to the laser active layer of the diode and at such an interval from the layer that the light entry face of the one end of the waveguide laying flat on the seating surface lies at the same height as the exit point of the beam. The method includes securing the fiber forming the waveguide on the seating surface, and then applying an external magnetic field to the diode to displace and pivot the beam in the laser active layer to adjust the beam relative to the fiber.
