Abstract: In a printer for printing an attributed character by printing a character part and an attribute part separately, the invented printer or typewriter is so constructed that only an attribute part, e.g., an underline part or a bold face part, is printed in case a printed character is detected to already have the attribute, i.e., is underlined, or bold face, thereby preventing a character part of the printed character from being double printed. This results in improved quality in printed characters and in complete clear character erasures. The printer is also effective for overprinting attribute parts to over a desired range of printed character.

Abstract: To simplify the position control for positioning DC servomotors, a microprocessor is used rather than costly, unreliable actual value sensors for the speed and the current in the power section, which microprocessor uses the signals from an incremental rotation sensor as an actual position sensor to calculate an actual position, an actual rotation speed and, in the manner of an observer, an actual current. Together with a nominal rotation speed and a nominal current, the microprocessor uses these values to calculate a nominal voltage for controlling the power stages of the DC servomotor. <IMAGE>

Abstract: A mobile and stationary bathing and therapy unit for the treatment of diseases, especially of the hands, feet and the genital area, and for whole-body treatment. The apparatus consists of several ultrasonic transmitters which act upon the inside of the metallic liquid containers into which the diseased parts of the body can be introduced. Surprisingly, it has been found that, by combining a medical liquid in the liquid container with the application of ultrasound to the diseased parts of the body, the course of the disease can be significantly shortened and better healing results can be achieved. The blood circulation is promoted, and the cleaning of the body parts is considerably facilitated. The apparatus is of simple design; it consists essentially of a common housing, in which the metallic liquid containers (12), the ultrasonic transmitters (10) and the necessary operating arrangements are present. <IMAGE>

Abstract: Method and means for evaluating the quality of audio and/or video transfer characteristics of a device upon which, or through which, audio and/or video information is contained, or passes, respectively. Both method and apparatus concern the evaluation of the quality of information transfer in the recording and playing back of a recording medium or in the transferring of audio and/or video information through an information handling device referred to as a throughput device. Unit evaluation is accomplished by establishing an input signal of known content, measuring selected parameters of selected parts of the input signal, feeding the input signal to the unit under test, measuring the parameters of parts of the output signal from the unit under test corresponding to the same selected parts of the input signal, and comparing the selected parameters of the input signal with the corresponding parameters of the output signal. Whether monitoring the quality of the signal transfer characteristics of a throughput device, a magnetic tape containing program material, or a video disc, master disc or replica, a "siganture" is created for the unit under test, and subsequent analysis of the unit as it progresses along a production line or of a copy made on the same or alternate recording medium results in a second "signature" which is compared against the first signature to make a determination as to the quality of the signal handling or transfer characteristics of the unit. In this manner, out-of-tolerance conditions can be automatically detected, thereby eliminating subjectivity and providing consistency in the quality level of device testing.

Abstract: A process for manufacturing CMOS devices is described, wherein two separate masks (37, 41) are used for the production of the gate regions (40, 42) of the two complementary transistors of the CMOS device, each of said masks allowing the formation of the gate region of only one of the two complementary transistors and being also used for the implantation of ions adapted to form the source and drain regions (39, 44) of said transistor. Accordingly only two masking steps are sufficient for the production of the gate (40, 42), drain and source regions (39, 44) of the CMOS devices, with a reduction of the costs related to the production of integrated circuits executed in CMOS technology.

Abstract: his invention provides a method and system for costbased resource scheduling. This invention develops an initial resource schedule. This schedule is then represented as a Schedule Precedence Graph, which is an acyclic directed graph consisting of nodes and arcs. Each node corresponds to a task to be performed, and each arc corresponds to a technological or assigned task precedence. Each node is assigned a cost, which corresponds to cost or savings due to delaying the task one time unit. In this invention, the Maximum Flow Procedure is iteratively invoked to determine which tasks can be profitably delayed.

Abstract: A proportioning control valve for an antilock control device having a cylinder (12) and first (20) and second (30) pistons mounted in the cylinder. The first piston (20) has a braking output pressure receiving portion and a first input pressure receiving portion. The second piston (30) slidably mounted on a small-diameter portion (23) of the first piston (20) has a second input pressure receiving portion. A spring is interposed between the two pistons to bias them away from each other. A stopper (31) is provided between two pistons to limit the movement of the second piston (30) toward the first piston (20). The cylinder (12) is formed with a control input pressure port (13) communicating with the input pressure receiving portion and an output pressure port (15) communicating with the output pressure receiving portion, and a brake pressure input port (14). With this arrangement, the output pressure which acts on the output pressure receiving portion of the first piston (20) will counteract the input pressure while the input pressure is below the cutting point, i.e. while the second piston (30) is out of contact with the stopper (31), and will counteract the sum of the input pressure which acts on the first input pressure receiving portion and the bias of the spring after the input pressure has reached the cutting point, i.e. after the second piston (30) has come into contact with the stopper (31). Thus   the ratio between the input pressure and the output pressure is adjustable by varying the total area of the first and second input pressure receiving portions before reaching the cutting point, and by varying the area of the first input pressure receiving portion and the bias of the spring after the cutting point has been reached.

Abstract: Electrical switchgear for simultaneous protection against excess currents, short-circuit currents and fault currents in individual circuits require the simultaneous use of a line circuit breaker and of a fault current circuit breaker. Such known switchgears, termed line and fault current circuit breakers, occupy a comparatively large amount of space in the distribution units because of the large space requirement of the fault current circuit breaker. The object of the invention is thus to develop switchgear which requires less space. To achieve this object it is proposed that the fault current protection pole of the single-pole switchgear also be arranged in a housing of modular construction, an auxiliary switch mechanism being connected between the fault current trip device (60) and the main switch mechanism, to compensate for the reduced tripping force of the fault current trip device (60), whose dimensions are limited, which auxiliary switch mechanism amplifies the trip pulse transmitted by a trip cam (61) of the fault current trip device (60) and thus leads to unlatching of the main switch mechanism. The principle of the construction of the auxiliary switch mechanism (44) is shown in a schematic representation, the sequence of the switch action being explained by instantaneous recordings of intermediate positions. <IMAGE>

Abstract: The circuit determines whether a video signal is from a video tape player or a broadcast signal source by measuring jitter of the vertical synchronization pulses. In one embodiment, every other time interval between the vertical synchronization pulses is measured and saved as a count, and each count is compared to the preceding count to determine whether sufficient jitter is present to indicate that the video signal is from a local tape player. In another embodiment all intervals between the vertical synchronization pulses are measured and a predetermined number thereof are saved as counts. The even and odd counts are then analyzed separately, and the extreme count (the most deviant count) of each group is eliminated. With the extremes eliminated, the overall deviation of the counts from an average is determined for each group (even and odd) and such deviations are compared to predetermined data (a threshold) to decide whether jitter is sufficiently large to indicate that the source of the video signal is a local tape player. 
     In still another embodiment timing data is generated corresponding to the period of at least one selected field in each of a plurality of selected frames. From this timing date, a maximum number is stored that corresponds to the greatest period and a minimum number is stored that corresponds to the least period of the selected fields. The minimum number is subtracted from the maximum number and the difference is compared to a threshold to determine the type of video signal. In an alternate embodiment, numbers corresponding to fields from successive frames are compared by a subtraction and the difference is compared to a threshold in order to make a decision as to the type of video signal. In both of the last two embodiments, the noise level of the video signal is constantly monitored. When the noise is above a threshold, the local signal is generated regardless of the information derived from the timing data.

Abstract: An optical recording medium has a transparent substrate (100) having prepits and/or pregrooves for system control signals and first and second recording layers (200, 300) formed thereon in order, which layers individually have a specific reflectance, transmittance and absorbance. A laser beam is irradiated on the transparent substrate side of the medium to record or read out information by detecting the variation of the amount of light as a sum of the reflected light from the boundary between the first recording layer (200) and the substrate (100) and the reflected light from the boundary between the second recording layer (300) and air; the system control signals are primarily obtained from the prepits and/or pregrooves. The first recording layer contains an organic dye having a transmittance of 10 - 50% and an absorbance of 40% or more against the wavelength of a laser beam used for writing while the second recording layer contains an organic dye having an absorbance of 20% or less and a reflectance of 25%   or more at the air boundary at the wavelength region of the laser beam. 
     The optical recording medium can be made by a coating on coating process wherein the transparent substrate having prepits and/or pregrooves is coated using two dye solutions in series to form the first recording layer and the second recording layer. The two dye solutions are prepared using two organic dyes which are each soluble exclusively in either a low polar solvent or in a high polar solvent.
