Abstract: According to the present invention, a belt-like recording medium on which an optional mark can be described and driving means thereof can be given to a usual analog image forming apparatus or digital image forming apparatus. Therefore, the mark can be also read in addition to usual reading of a document, thereby causing the mark image to be automatically described or transferred into usual document images. An embodiment in which only a mark can be independently described at an optional position is included as one of the embodiments of the present. 
     By an analog or a digital image forming apparatus according to the present invention, it is possible to automatically insert such a mark as trademark, logograph (or logotype), etc., to an optional position on a sheet of image transferring paper. Therefore, an operator can be freed from such a troublesome work as attaching the mark to a source document before printing, etc.

Abstract: A TE-TM polarization manipulating (i.e., splitting, combining or filtering) device is constructed from substrate-supported dielectric thin film waveguides. In a 3-port device, two waveguides (10,12) have cores (10.1, 12.1) of different materials and different effective refractive indices. The waveguide cores overlap in a first transition section (18) and one waveguide core has an adiabatic taper (12.6); in this section they also separate adiabatically and are coupled to a second (e.g., output) section (16) where the waveguides are physically separate and optically decoupled. In a 4-port device, two additional waveguides are coupled in a second adiabatic transition section to the first transition section to enable TE or TM modes to be coupled straight through the device from one input port to a directly opposite output port or to be crossed-over from one input port to a diagonally opposite output port.

Wavelength-division multiplexer/demuitiplexers (50,70) couple the optical fiber to the headend terminal and the distribution terminal to enable bidirectlonal transmission. The subscriber terminal is responsive to a control signal transmitted to the subscriber terminal for enabling a receiver (96) therein to receive television signals transmitted to the subscriber terminal over a selected one of said different given frequency channels. The headend terminal includes a digital switch (40) that is operated in coordination with the control signals that are transmitted to the subscriber terminals for enabling reception of only selected frequency channels in the respective subscriber terminals, by frequency positioning the television signal indicated by the service request signal (66) received from a given subscriber terminal witbin the composite signal for transmission to the given subscriber terminal over the given frequency channel enabled by the control signal that is transmitted to the given subscriber terminal.

Abstract: A transverse mode stabilized AℓGaInP visible light laser diode in accordance with the present invention has a characteristic in that, instead of forming a built-in refractive index distribution in an active layer (14) along a junction plane by means of the absorption loss of the oscillated light in the conventional transverse mode stabilized AℓGaInP laser diodes, an optical guide layer (15) having a ridge stripe portion is formed on the active layer (14), and a refractive index distribution is formed by the thickness difference of the optical guide layer (15). In particular, the present laser diode employs as the current blocking layer (18) to be formed on the sides of the mesa, an AℓXGal-XAs layer which does not give rise to an absorption loss of the oscillated light.

Abstract: Emission antenna for hyperthermia having optimised physical dimensions and which heats the biological tissues in depth and uniformly, with operating frequencies below 500 MHz, and focusing the RF energy (phased array). The use of a dielectric ceramic of high permittivity (ε r  = 80; 160), in conjunction with the technology of microstrips (patch antennas), permits the construction of emission antennas of extremely restricted dimensions and of reduced weight, having operating frequencies below 500 MHZ. The ceramic employed has low losses and permits very high levels of efficiency to be achieved. The emission antenna may be used on its own or may be employed advantageously in the construction of emission antennas which are flexible and conformable, in order to obtain a uniformity of deposition of power exceeding that which can be achieved using conventional emission antennas, with the same surface area and frequency. It is particularly suitable as a module for the construction of phased arrays.
