Abstract: In a cross-polarization interference cancellation system operable in response to desired and undesired or interference source signals which are obtained from polarized waves having planes of polarization orthogonal to each other and which are produced in accordance with clock signals having a predetermined clock frequency, an interference signal is included in the desired signal and is derived from the interference source signal to be removed from the desired signal by the use of an interference canceller and to be produced as an interference free signal. The interference free signal is demodulated into demodulated signals, error signals, and quadrant detection signals by a demodulator unit. In this event, the quadrant detection signals alone are stably demodulated by the use of specific clock signals which are sent through a frequency doubler operable to double the predetermined clock frequency of the clock signals. The interference canceller comprises a transversal filter and a control signal generator for supplying the transversal filter with control signals stably produced by the control signal generator. As a result, the interference canceller is stably operated in response to the control signals.

Abstract: In a semiconductor device according to the present invention, a diffusion region (5,7) on the surface of an output region 84) for a substrate electric potential and a element segregation region (6) under a field insulating layer (2) are electrically connected together, at the end portion of the field insulating layer (2) and in the diffusion region (5,7). Thus, the substrate electric potential can be easily output at the surface of the output region, even if the diffusion region (5,7) on the surface of the output region is formed shallow by a low temperature thermal treatment due to a fine designing of the semiconductor device. In the fabrication process according to the present invention, after formation, by patterning, of the protruded output region (4) of the substrate electric potential with its end portion being tapered, impurities are implanted in the tapered portion. Therefore, the diffusion region (5,7) on the surface of the output region and the element segregation region (6) under the field insulating region (2) are electrically connected together through the diffusion region (5,7) on the tapered portion, which allows easy output of the substrate electric potential from the surface of the output region (4), even if the diffusion region on the surface of the output region is formed shallow by lower temperature thermal treatment due to a fine designing of semiconductor device. The process of patterning the output region in the form of a protruded shape is also required, but the process is completed through a procedure using only one ion implantation and one low temperature thermal treatment (selective oxidation), thereby significantly simplifying the fabrication process.

Abstract: The present invention is concerned with a fatty composition containing more than 50 wt.% fat, comprising, calculated by weight of fat:
     (a) 0.5 to 40 % unrefined olive oil;   (b) 5 to 80 % polyol fatty acid polyesters; and optionally   (c) less than 94.5 % refined triglyceride oil.   
     The fatty compositions according to the invention were found to have a mouthfeel that is very much alike that of olive oil. Futhermore, surprisingly, the long aftertaste, which is characteristic of olive oil based salad oils, is also observed for the combination of polyol fatty acid polyesters and unrefined olive oil. 
     Another aspect of the present invention is the use of polyol fatty acid polyesters as a replacement for refined olive oil in olive oil based fatty compositions which contain from 0.5 to 40% of unrefined olive oil. 
     Yet another aspect of the present invention is the use of a fatty composition according to the invention described hereinbefore as a salad oil.

Abstract: The invention involves the detection of odors using an odor detector including an n-type semiconductor sensor having an electric resistance responsive to odor molecules adsorbed thereonto. An ozonizer is provided within a test compartment to contact the detector with an ozone gas for the purpose of calibrating the detector to an initial zero setting. The test compartment also includes a ventilation fan operable to draw a purging air into the compatment. In order to minimize the time required to bring the detector to the initial zero setting, a computer is used to selectively actuate the ozonizer and the ventilation fan in a controlled manner. Before starting a new detection cycle, an operator selects a specific table of optimal pattern for quick recovery to the zero setting from among a plurality of tables stored in the computer, based on certain factors such as the identity and concentration of previously detected odorant substances, etc.

Abstract: The functions of two virtual operating systems (e.g. S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated form 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices. The S/88 processors across the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations. The S/88 and S/370 peer processor pairs to execute their respective Operating Systems in a single system environment without significant rewriting of either operating system. Neither operating system is aware of the other operating system nor the other processor pairs.

Abstract: An electro-acoustic transducer utilizing a plurality of flexural bars or staves to form an interface member between the electrorestrictive driver element and the water transmission medium. The staves are fastened to end plates to form a concave barrel-shaped structure that results in substantial mechanical amplification. The driver element consists of a stack of electrorestrictive elements with the stack's axis essentially coincident with the transducer's longitudinal axis. A tension member, threaded at both ends, passes through holes in the end plates and through an axial hole in the stack. Nuts at each end of the tension member are tightened to provide the required compressional "bias" to the stack. The transducer offers the advantages of lower cost of fabrication, increased amplification of the flexural driver interface elements and improved capability to withstand hydrostatic pressures.
