Patent EP-0411566-A1 (EP)
Inventor: YAMAZAKI SHUNTARO C O NEC CORP
IPC: H04B10/07
Filed: 1990-07-31
Abstract: In the automatic frequency control system the output frequency of a local oscillator (4) is swept by a frequency sweep signal obtained from a sweep circuit (14) and FM-modulated with a frequency shift signal generated by an oscillator (10). The FM-modulated local frequency is combined in a balanced receiver (3) with an input optical signal and applied to a frequency discriminator (8). A frequency shift signal component derived from the discriminator output is compared by a phase comparator (11) with the frequency shift signal to verify whether or not the local oscillation frequency is in a predetermined range with respect to input signal frequency. When it is in the predetermined range, the system operates to terminate the frequency sweep signal and remove the frequency shift signal and is switched to oscillation frequency control of local oscillator by using a d.c. component of the frequency discriminator output.

Abstract: In a procedure for analysing gaseous media, in particular for determining the concentration of a gas in a gas mixture, by means of microwave spectroscopy, the microwave radiation is coupled in pulsed form into a resonator which can be tuned to different frequencies and which is situated in an evacuated receiving vessel. The gas mixture to be examined is admitted as a pulsed molecular beam into the receiving vessel using air as carrier gas. The mixed state formed by the microwave pulse produces an emission which, during the intervals in the incident microwave pulses, is coupled out from the resonator into a receiving unit. After down-conversion to frequencies preferably in the region below 50 MHz, the test signal is digitised and evaluated, during which process a Fourier analysis may be carried out.

Abstract: An apparatus (1) for measuring visual acuity comprises two rotating charts (3) which are mounted within a housing (1) having a window (2) in the front thereof. The housing is illuminated and the charts (3) are placed upon plastic rotating disks (10,11) which transmit light. The disks are rotated independent of each other in order that one chart may be viewed through the window in the apparatus. Adjacent the window are a series of LEDs (4) which serve to indicate to the patient which line of the optotypes on the chart is to be read. At the bottom of the device there is a display (9) which indicates the number of the line being read and the visual acuity that this represents. The activation of the indicators and the rotation of the disks are controlled via a wireless remote control (20).

Abstract: A first machine part rotates about an axis of rotation. A circular movement of a second machine part takes place without rotation, as a result of translational motion of at least the second machine part along two axes of translational motion (X, Y) in a plane of movement (XY). The centre (O) of the circular path (C1) lies on the axis of rotation. A sensor (5) is arranged on one machine part and a sensed surface (8) is arranged on the other. The sensor (5) is circular (CO) in the plane of movement (XY) and is sensitive in two measuring directions (A, B). It is arranged outside the axis of rotation. Before the measurement, the sensor (5) experiences a desired deflection (d) from the sensed surface (8). The deflections of the sensor (5) are plotted by cartesian coordinates. The sensed surface (8) preferably comprises one or more planes (E1, E2) parallel to the axis of rotation. The rotational movement and the circular movement are coordinated with one another, so that, with a constant desired deflection, the sensor (5) describes an auxiliary circular path (C2) concentric with the circular path (C1). The actual deflection is displayed and compared with the circular desired deflection. The method is suitable for measuring errors and for checking the quality of movements of a machine which are generated about an axis of rotation and/or with two axes of translational motion. <IMAGE>

Abstract: An apparatus for producing a single crystal grown by Czochralski method includes a winding drum (64) disposed in a case (24) for winding up and down a flexible pull wire (20), a power transmission mechanism (M2, 46 - 56) for driving the winding drum (64), and a bearing unit (60) for rotatably supporting the winding drum (64). The power transmission mechanism (M2, 46 - 56) and the bearing unit (60) are disposed outside the case (24) and isolated from the furnace atmosphere surrounding the winding drum (64) and the pull wire (20) in the case (24). With this construction, metallic dust produced by abrasion from the power transmission mechanism (M2, 46 - 56) and the bearing unit (60) has no influence on the condition of the furnace atmosphere and hence the quality of a single crystal being pulled upwardly by the pull wire (20).

The compounds are also of use in combatting other conditions where inhibition of PDE type IV is thought to be beneficial. The compounds can be prepared by treating the corresponding 6-amino uracil with sodium nitrite and formic acid in an excess of formamide and adding sodium dithionate to reduce the resulting 6-amino-5-nitroso compound to give the 5,6-diamino compound that ring closes with the excess of formamide.
