Patent EP-0407031-A2 (EP)
Inventor: ARCURI SALVATORE
IPC: H04J3/00
Filed: 1990-05-31
Abstract: High speed communication of digital information is accomplished using an analog transmission format. A transmitter receiving digital data in parallel multibit words converts digital words in conversion clock cycles to a single analog signal relative to a DC level. The transmitter also includes a reference pulse generator which combines a reference pulse with the analog levels generated by the converter to form an analog output for transmission to the receiver. The receiver includes a detector receiving the analog output. In response to the reference pulse, the receiver generates a recovery clock. A flash analog-to-digital converter converts the analog levels in the analog output to multi-bit digital outputs. The parallel multi-bit words are regenerated in recovery clock cycles from sampling the multi-bit digital output once per cycle. Thus, by using a digital to analog to digital systems, effective bit rates are achieved that are higher than the switching speeds of the transmitter and receiver.

Abstract: The invention relates to a method and a device with which an FM or PM modulated signal can be detected from a carrier directly, without the disadvantages that the use of an analog or a digital phase lock will cause. The direct detection is realized so that the instantaneous frequency or phase of the input signal is measured by direct time interval measurement so that the time measurement resolution is increased by using a delay line. The detected result is already digital, whereby no separate analog-to-digital converter is required.

The arms 6, 7 and 8 are connected to one another by means of plug or screw connections. The frame carries a camouflage net 18. So that the camouflaged object has an irregular appearance, hence the camouflaging effect is especially high, the frame consists of arms 6, 7 and 8 which are of variously irregular shape. The frame and therefore the camouflage have different heights on the two sides L, R of the longitudinal axis of the object. <IMAGE>

Abstract: Described is an optical beam-splitting system for partitioning the real image of an object (1) into partial images (8) onto image receivers (16) arranged with a distance between them, comprising an objective lens (2) and optical elements (4) arranged in the ray path behind the objective lens (2). 
     Each optical element consists of at least one reflecting plane deflecting the path of rays and that the optical elements intercept partial luminous fluxes not interfering with each other, and the optical elements are arranged outside of the overlapping region (VXE) of the beams emanating from the extremities of the object and passing through the objective lens and in front of the image plane pertaining to the objective lens. 
     This construction enables to obtain images spaced with a distance between them so that the partial images can be registered without loss by image receivers, the receiving surfaces of which cannot be arranged without distance one next to the other. Additionally, a partial overlapping in the peripheral areas of the partial images should be possible and no additional distortions should ensue other than those caused by the objective lens.

Abstract: The present invention relates to a damper device which comprises a fixed member and a movable member that are positioned relative to each other, one being inside of the other, electroviscous fluid sealed in between said two members, and electrodes opposingly arranged at respective positions of the two members to allow relative flow of the electroviscous fluid. The portions of the movable and fixed members where they are in sliding contact are shielded against said electroviscous fluid by a flexible member provided between these two members. 
     When the damper device of such construction is used as a position control means, a voltage is applied to the electrodes to stop and position the movable member while the voltage application is suspended to cause the movable member to move. 
     The apparatus for manufacturing semiconductors according to the present invention is characterized in that an arm (41) is provided on the movable member (40) to move along the axial direction of the guide bar (42) when the movable member moves, a flexible member (45) is provided between respective ends of the fixed guide bar and respective ends of the arm to maintain the internal space liquid-tight, and an electroviscous fluid is sealed inside the flexible member and in between the arm and the guide bar. A positive and a negative electrodes are formed by utilizing two opposing members such as the arm and the guide bar, to which a voltage power source (48) is connected. When the movable member is to be stopped and positioned, a voltage is applied to the electrodes while said voltage application is suspended when the movable member is to be moved.

Abstract: A luster detector arranged such that an output light beam of an LED is applied to a surface through a light projecting lens as an irradiating light beam having a predetermined width. Rays of light reflected from the surface are applied through a condenser lens to a line sensor. Of the rays of light reflected from the surface, the rays of light reflected regularly form a light spot on a light detecting section extending in the longitudinal direction of the light detecting section. Hence, even if the light receiving position is shifted, the light detecting operation is positively achieved. A detecting circuit determines the light reception distribution of the sensor to detect the luster of the surface.

Inventor: MARTIN HANS DIPL-ING
IPC: F16D35/02
Filed: 1993-03-26
Abstract: The technical problem from which the invention takes its starting point is the excessively low idling speed of fluid friction couplings. This has the effect that the coupling does not cut in when required. The object of the invention is therefore by simple constructional means to achieve an increase in the idling speed and hence reliable cutting in of the coupling. This object is achieved according to the invention by the fact that a so-called differential pressure valve is arranged in the return passage of the fluid friction coupling, i.e. between the work chamber and the reservoir chamber, this valve opening towards the reservoir chamber at a defined differential pressure between the work chamber and the reservoir chamber. This differential pressure valve is preferably designed as a spring-loaded ball valve. It has the advantage that it is simple to install, adjust and retrofit. The area of application of such fluid friction couplings is in the driving of fans for cooling motor vehicle engines. <IMAGE>
