Abstract: A satellite communication system with a variable coding rate maintains all the channels connectable at all times without resorting to an extra frequency band associated with one carrier wave on a satellite transponder and otherwise required to accommodate the simultaneous occurrence of multiple call requests which is rare. The system selectively changes the coding rate of data to implement the transmission of massive data without the need for an increase in the frequency band on a satellite transponder, contributing a great deal to the efficient use of frequency bands available with a satellite transponder

Abstract: In an optical projection form-grinding machine, a measuring probe (11) is attached to the grinding spindle head (1), with which measuring probe (11) a workpiece (4) is alternately traced for grinding operations. During each switching operation of the measuring probe (11), the displacement information supplied at this moment from displacement measuring devices (8, 9) of a workpiece slide (5) is transmitted by a control device (10) to a storage device (12). This stored displacement information can be used to measure the workpiece (4) directly after a machining operation in order to draw conclusions therefrom for the further machining. <IMAGE>

Abstract: Presence, absence, and adequacy of length of component leads (4) are detectable by engaging each lead (4) with a corresponding interposer (50) and monitoring the amount of displacement of each interposer or plunger (50) in response to the lead. Each plunger is provided with an optic fiber (56) for guiding and directing a light beam from a transmitter (22) to a receiver (20) of a sensor (18) when a lead is missing or too short. The lead engaging portion (60) of the plunger (50) is interchangeable to accommodate different lengths of leads and heights of cut and clinch anvils (30). For DIP components, each half of the inventive device receives all of the leads on one side of the component, with an individual piston (50) for each lead. Thus, mirror image devices may be used for oppositely spaced rows of leads of a DIP, with the spacing between the mirrored halves of the device being adjustable according to the center-to-center (CTC) spacing between leads on opposite sides of the component body. Each plunger of one of the mirror halves is simultaneously engaged by a fluid common to the remaining pistons thereof for extension, as well as retraction, of the lead engaging portions.

Abstract: An improved optical head for reading information recorded on a reflected medium. The optical head (100) uses a hologram lens assembly (113) having a transparent plate and a hologram lens (114A), the transparent plate being obliquely positioned relative to a forward and a return beam paths. The transparent plate corrects beam aberrations in a laser beam emitted by a semiconductor laser (111) on the forward beam path. The hologram lens diffracts the laser beam on the return beam path onto a photodetector (119). Both the transparent plate and the hologram lens add beam aberrations to the defracted laser beam on the return beam path for tracking purposes. The hologram lens assembly may also include a second hologram lens (114B), preferably a three beam diffraction grating, for tracking purposes. The hologram lens and the diffraction grating may be located on the obliquely positioned transparent plate or on other transparent plates.

Abstract: Disclosed is an optical pumping-type solid-­state laser apparatus in which a semiconductor laser device (11) is used as a light source for optical pumping. The solid-state laser apparatus includes first and second photodetectors (12,13). The former detects the amount of light emitted from the semiconductor laser device, and the latter detects the amount of laser light transmitted through a filter plate (14) which has the same light-absorbance characteristics as that of the solid-­state laser. In accordance with the detected results, a driving circuit drives the semiconductor laser device to obtain a laser beam with an appropriate output level and a temperature regulator regulates the temperature of the semiconductor laser device so that the wavelength of the laser light to be emitted therefrom is accurately adjusted to be the same as that of the light to be efficiently absorbed by the solid-state laser. The laser beam with the accurately adjusted wavelength is used for optically pumping the solid-­state laser.

Abstract: An advantageous method of fabricating lasers adapted for use in a multichannel analog optical fiber communication system (10), e.g., a CATV system, is disclosed. A laser generally can be used in such a communication system only if it meets, inter alia, very stringent intermodulation specifications. To identify such lasers typically requires extensive testing. It has now been discovered that certain readily determinable parameters can be used to predict the intermodulation behavior of a given device. This discovery makes possible a simpler, and therefore less costly, process of identifying suitable lasers, resulting in a more economical method of making lasers for the stated application. The method comprises measuring the light versus current (L versus I) characteristic of a given laser, determining therefrom the first, second, and possibly higher, order derivatives of L with respect to I, and determining therefrom a parameter that is a predictor of the distortion behavior of the laser. Exemplarily, the quantity is the normalized second order distortion (2HD/C), defined as 20 log (mL˝L/4L′²), where m is the modulation index, and L′ and L˝ are the first and second derivatives, respectively, of L. 2HD/C has a pronounced minimum at I = I op , the current at which L˝ = 0. Advantageously, lasers are selected that have 2HD/C less than a predetermined value (e.g., -70dbc, with m = 0.04) over a relatively wide current range (e.g., at least 4 mA).
