Abstract: A method of deburring and removing the chips from holes is described. The method can be used in particular in series production, preferably when deep intersecting holes or deep holes leading into one another have to be produced, e.g. in drive units and door closers with a hydraulic or pneumatic circuit. The invention consists in the hole first of all being rough-drilled by a cutting action and then being re-worked by erosion for the purpose of removing the chips and deburring. The erosive re-working of the hole (2) is effected by means of an erosion electrode (10). In the process, the burr (3a) and the chips (7) are removed by erosive action. <IMAGE>

Abstract: An electric traction motor provides forcible rotary or linear positioning of a motor shaft by pairs of actuators that are electrically stimulated to produce tractive cyclical walking. Smooth walking actuators provide high mechanical efficiency and long life by eliminating sliding friction. The actuators are stimulated by a high efficiency electrical drive system to position relatively large-area traction members that match the speed of the motor shaft. The preferred embodiment comprises piezoelectric actuators having layers of shear deformation piezoelectric material. Conventional bearings and lubrication are not required, and embodiments of the motor can be constructed to operate satisfactorily in intense magnetic fields and severe ionizing radiation. The traction motor can range in scale from microscopic to very large, and positioning accuracy on the order of nanometers has been demonstrated.

Abstract: The invention relates to a spring energy accumulator for load transfer switches of tap changers, which accumulator rotates a shaft in a sudden manner when it is released and consists of a drive disc, two energy accumulator levers, a spring lever and an output drive disc as the essential components which are supported on a common axis and can rotate in each case independently of one another. In this case, the drive disc consists of two partial drive discs, which each support a drive element. The drive elements project into the plane of the two energy accumulator levers, between which a spring is pivoted, and act on said spring. The deflection of in each case one energy accumulator lever and hence the tensioning of the spring is caused by a drive element acting on said lever while the respectively other energy accumulator lever is held in its position by an output drive element of the output drive disc until the sudden release takes place as a result of the latching system.

Abstract: In order to obtain precise submodel control in a central processing unit, there is provided a subcounter which is controlled to count up from a begining count as an instruction is executed and to count back down at the same rate to the reference count to obtain an effective delay before processing of the next instruction to be processed during normal program execution is started. Instruction transfer and decoding of the new instruction entering the pipeline is inhibited until the subcounter's most significant bit ("sign bit") changes state. If the subcounter is allowed to count during the entire count up and count down periods, a derated mode of 1/2 is achieved. To obtain other fractions, the subcounter is controlled to count periodically during one count direction period and to count full time during the other count direction period. In the exemplary embodiment, 1/4 and 3/4 derating is selectively achieved by the use of a modulo 3 counter which allows the subcounter to count only 1/3 the time in one or the other of the subcounter count up or count down periods.

IPC: H02M7/10

Abstract: The circuit according to the invention operates with a voltage multiplier cascade which requires two alternating, non-overlapping pulse trains which are generated by a pulse generator. Specific applications, for example contact-free chip cards, obtain their supply voltage from an AC voltage which is induced in a coil and is rectified by means of a bridge rectifier. In this case, a voltage drop occurs. When the pulse generator is operated with the supply voltage, the amplitude of the output pulses is smaller in comparison, that is to say a further voltage drop occurs. Thus, according to the invention, the pulse generator passes the pulses for supplying the cascade directly from the AC voltage rather than from the rectified operating voltage. This results in a greater amplitude and improved efficiency. A possibility is also specified to block the pulse generator such that it does not represent any load for the AC voltage.

Abstract: . Disclosed is a stereophonic sound reproducing apparatus which produces a range of sounds capable of being heard naturally by a listener. The apparatus has left and right acoustic sources whose sounds are picked up by a sound pick-up mechanism modeled after human auditory organs. The acoustic sources are emitted from two directional speakers in a sound field toward the reflective walls of the sound field in such a manner that the acoustic sources will not interfere with each other. The listener hears the sounds from the two speakers after the sounds are reflected by the walls. The apparatus is capable of reproducing deeper stereophonic sound than the conventional stereophonic sound reproducing apparatus.

Abstract: A magazine containing a number of standardized magnetic tape cartridges, for loading into an automated device in which a selected cartridge can be removed from the magazine and inserted into a data reader, has a number cartridge receptacles therein formed by a number of dividers extending the width of the magazine. Each divider consists of electrically conductive polymer, and has an electrical connector at a bottom thereof which extends through a bottom of the magazine, and which engages an electrically conductive path to ground in a base element on which the magazine rests within the device, thereby providing an electrostatic discharge path for each cartridge in each receptacle. Each divider also has an element extending into the receptacle, which is engaged by the cartridge as it is being inserted into the receptacle. Based on the standardized configuration of the cartridge, the element has a profile which is configured to permit the cartridge to move over the element only when the cartridge has been inserted into the receptacle into a selected orientation. If the cartridge is attempted to be inserted into the receptacle in any other orientation, the profile prevents such insertion, thereby insuring that each cartridge will always be inserted in its receptacle in an orientation for correctly inserting the cartridge in the data reader when it is automatically removed from the magazine. For a cartridge properly oriented in the receptacle, the element also serves as a spring to urge the cartridge against a neighboring receptacle, to insure good contact with the electrostatic discharge path.

Abstract: As a method of measuring a sectional figure of a living body by using a resonance medium in the living body, a MRI device has been introduced. However, the MRI device is not applied to bones, teeth which are poor in resonance-related protons, electrons and molecules. According to the invention, electrical, magnetic and electromagnetic fields are applied to the bones and teeth using a resonance medium. By using the resonance of the resonance medium, figure and displacement of the bones and teeth are measured. In more detail, proton spin and electric spin are applied to the bones and the teeth so that the spin state is measured to specify the figure and displacement by means of the MRI device. Otherwise, a resonance circuit which comprises the resonance medium is applied to the bones and teeth which changes rotationally and linearly. The resonance circuit changes its resonance frequency according to the displacement of articles to be measured. As one example, LC resonance circuit is exemplified which changes its inductance and capacitance, and an antenna circuit which changes the length. 
Frequency which is changed by an oscillating circuit is applied to the resonance circuit. The resonance frequency is read out by an output change from the oscillating circuit influenced by the resonance of the resonance circuit. On the basis of the resonance frequency of the resonance circuit, the displacement of the article are measured. Alternatively, an echo-back method may be applied.

Abstract: An apparatus of the present invention can achieve an improved image quality, irrespective of either a still image or a motion image to be obtained, when a scanning line number is converted. To this end, an interlaced scanning signal is input to a field delay circuit (13) and to a vertical highpass filter (21a), the output of the field delay circuit (13) is input to a field delay circuit (14) and to a vertical lowpass filter (22), and the output of the field delay circuit (14) is input to a vertical highpass filter (21b). The outputs of the vertical highpass filters (21a, 21b) are added together at an adder (24). The output of the adder (24) is added by an adder (23) to the output of the vertical lowpass filter (22) to create an interpolation signal. The interpolation signal and direct-type signal, being time-compressed, is coupled to a switch (18) where they are alternately selected. In this way, it is possible to create progressive scanning signals.
