Title: Method of and apparatus for phase compensation for still picture and slow motion functions in video equipment
Inventor: SCHULEIN REINHARD
IPC: H04N5/783
Filed: 1983-08-30
Abstract: A method of and apparatus for compensating the phase modulation of the vertical sync pulse during the auxiliary functions of still picture and slow motion in video recording and/or reproduction equipment, without using a delay line. This is achieved in that an artificial vertical sync pulse is used which alters appropriately and compensates the phase jump. Depending on the video system, the invention can be embodied in a simple manner according to the track displacement specific to the system and the switching over of the video heads for the auxiliary functions, the position of the artificial vertical sync pulse being switched over alternately and adapted to the particular system. A microcomputer may be provided in a particularly advantageous and simplifying manner for the production of the alternating artificial vertical sync pulses and at the same time also renders possible the production of a key-in pulse, the production of the video-head switching pulses, a drop- out recognition and a time-lapse operation.   <IMAGE>

Title: Photoelectric conversion devices
Inventor: YAMAZAKI SHUNPEI
IPC: H01L31/06
Filed: 1983-12-22
Abstract: In a non-single-crystal semiconductor PIN photoelectric structure 3 in which the light is incident on the P-type layer 4, the layer 5 is doped with a P-type impurity, such as boron, distributed so that its concentration decreases towards N-type layer 6. This ensures that the whole of the I-type layer 5 is depleted in operation and compensates for N-type doping due to oxygen, carbon or phosphorus atoms incorporated during the deposition process. The structure may be formed with the P-type layer in contact with a transparent electrode 2 on a transparent substrate 1 (as shown) or may be inverted. The non-single crystal material may be Si, SiC or Ge and may be in amorphous, semiamorphous or microcrystalline form. Amorphous Si may contain hydrogen or fluorine. <IMAGE>

Title: Method of and apparatus for influencing the boundary layer of a body experiencing predominantly stochastic flow fluctuations
Inventor: LURZ DR WERNER
IPC: B64C23/00
Filed: 1984-04-26
Abstract: To influence the fluid flow (having flow velocity U0) in the boundary layer of a body over the surface 8 of which the flow passes for reducing resistance or preventing flow separation, during predominantly stochastic flow fluctuations the frequency of the flow is sensed by a sensor 1. The sensed value is passed to an analyzer control circuit 2 which, in turn supplies a signal to a vibration transmitter 3 for introducing a vibration into the fluid flow for either damping or amplifying the flow. A periodic vibration of the same frequency can be superposed on the predominant stochastic frequency. In an alternative arrangement (Fig. 1) a countersignal can be impressed on the original vibration at the same location where the original vibration is sensed. <IMAGE>

Title: Compensating an electrical signal varying non-linearly with time
Inventor: HAFNER PETER
IPC: G01D3/02
Filed: 1984-08-16
Abstract: For at least partially compensating an electrical signal varying non-linearly with time, for instance an interference signal US (Fig. 3) superimposed on a useful signal UN in a flowmeter 1-4, sampled values VA0, UA1, etc are taken at equal time intervals from the electrical signal or from a total signal containing the electrical signal. the values being stored in registers 10p, to 10o. Each time (p + 1) sequential sampled values are multiplied (11p to 11o) by weighting factors Gp to Go which are proportional to the binomial coefficient (<p>k), the sign of each second product being inverted. The products formed in this manner are summed (12) to form a sum signal. In the sum signal obtained in this manner, all the terms of the polynomial representing the non-linear signal in the time interval in which the sampled values were taken are eliminated up to the (p-1)th degree. Thus. if the non-linearly varying signal can be completely represented in the respective time interval by a polynomial of degree n</=p-1, said signal is completely elminated from the sum signal. If the degree of the polynomial is higher or if the polynomial representation in accordance with Taylor's theorem is possible only approximately with a remainder, a residual error can be diminished by increasing the number of sampled values processed. <IMAGE>

Title: Charge/discharge circuit
Inventor: NAKAMURA CHIAKI
IPC: H02J1/00
Filed: 1985-05-20
Abstract: A power source 1, particularly a solar battery, is connected via reverse current prevention diodes 5, 6 to a capacitor circuit C1, C2 for holding electric charge from the source 1, and a voltage clamping 3 limits the voltage across the capacitor circuit. The capacitor circuit includes a capacitor C1 having a relatively large capacitance, a switching circuit 2 in series with capacitor C1 and a capacitor C2 having a relatively small capacitance. The switching circuit 2 is controlled by a circuit 4 which has voltage threshold detection circuits (8 to 11), (Fig. 4), responsive to the voltages at points a and c in Fig. 1. Provision of the small capacitor C2 reduces the initial delay time before the output voltage on the capacitance circuit, when charging from source 1, rises to a level sufficient to operate integrated circuit load 7. Switch 2 is thereafter turned on and off so as to maintain the output voltage at point c in the range above the minimum operating voltage of the load 7 while the capacitor C1 is charging up. <IMAGE>
