Title: Receiving antenna for ultrashort waves
Inventor: POTSCHKAT GUENTER DIPL ING
IPC: H01Q9/32
Filed: 1988-06-30
Abstract: In order to enlarge the bandwidth and to simplify the construction, it is proposed for a VHF receiving antenna that a half-dipole arrangement consisting of a plurality of half-dipoles (running approximately parallel to the axis) of different length be fitted on the tubular section forming the lower half-dipole. A broadband transformer is arranged between the dipoles and the end of the coaxial connecting cable running within the lower tubular section. The lengths of the half-dipoles are selected such that they have resonant wavelengths offset by a quarter of a wavelength with respect to one another, in the sense of forming sub-bands which are adjacent to one another without any gaps. The half-dipoles, including the broadband transformer, are surrounded by an insulating material cylinder which is placed on the lower tubular section.

Title: Data processing circuit to process data with different bit lengths
Inventor: MURAMATSU KIKUO
IPC: G06F12/06
Filed: 1988-09-16
Abstract: Traditional data processing circuits give problems in processing data with different bit lengths. The data processing system with a memory device has even-numbered addresses and odd-numbered addresses. In both long data bit mode and short data bit mode, an even-numbered address and an odd-numbered address are accessed. The data processing system has a circuit (200) to carry out the data communication with an odd-numbered address via an upper data bus (6) or a lower data bus (5) in short data bit mode, and a circuit (150) to carry out the data communication with an odd-numbered address via the lower data bus (5) in both long and short data bit modes. Because of this construction, data communication via the lower data bus only, for both even-numbered and odd-numbered addresses, is made possible in short data mode. This data processing system can be used, for example, in a microcomputer. <IMAGE>

Title: Ultrasonic transducer array element apparent prepositioning - feeds signals, received by active aperture of transducer array, to several delay units
Inventor: HASSLER DIETRICH DIPL ING
IPC: G10K11/34
Filed: 1989-12-06
Abstract: The correction uses an adaptive aerial for compensating heavy interruption of the sound beam by displacement of a tranducer array nearer to the interference point.  The apparent displacement (retroprojection) of the transducer elements (W1,2...) is used for the supply of signals (S1,2) to a number of delay units (31,32) after resection from an active aperture of the ultrasonic transducer array (8). The number of the delay units corresponds to the number of the apparently displaced transducer elements.  The delay times of the units are so chosen that the output signal (21,22) of each delay unit focusses the active aperture to each location of the apparent displaced transducer element.  The obtained output signals may be electronically focussed. USE/ADVATAGE - For examination of intestinal tissues, with improved correction of image interferences.
