    摘要： A multi beam track system and method is used for the retrieving of information stored in optical memories like optical disks. The information carrying beams reflected on the surface of such a optical disk results in spots on the surface of a detector array. Because these beams are very close to each other, the resulting spots tend to overlap so that cross talk conditions between neighboring channels occur. As result the S/N ratio becomes worse. According to the present invention a plurality of laser beams arranged in a row is used, where the laser beams are linear polarized and the polarization of neighboring beams differ by 90.o slashed., i.e. neighboring laser beams have perpendicular linear polarization. After reflection on the surface of the optical disk the row of reflected laser beams is separated into two rows by an separating means which is polarization dependent so that beams are separated in space according to the polarization. Such a separator can be a polarizing beamsplitter or a birefringent prism crystal. As a result two spacially separated rows of laser beams are achieved, which can be detected by two separate detectors. As result no overlap between neighboring spots occurs on the surface of the detectors, resulting in the elimination of crosstalk.

    摘要： The invention concerns a high storage capacity ROM-RAM disk and a process for reading and writing to the ROM-RAM disk. T he aim of the invention is to devise a ROM-RAM disk and a process making it possible to read ROM and RAM simultaneously, to read the ROM area and at the same time write to the RAM area and to provide the largest possible volume of memory. The invention comprises two alternative designs. In a first design a ROM-RAM disk contains an area having both ROM and RAM memory structures as of a certain radius or diameter, establishing therein, at a constant rotational speed, a scanning/writing speed which ensures a reading/separation of the data stored in the ROM-RAM structures. In a second design, the available storage area is taken up entirely by a ROM-RAM storage area, where RAM memory structures have a reduced data rate in order to form, a length of memory structures necessary for separating the data stored in the ROM-RAM storage area.

    摘要： In laser feedback systems of an optical memory the most suitable feedback gain value depends on the type of optical disks used. According to the invention a system and a method is provided which finds by way of an iteration a suitable maximum feedback gain value so that the feedback system does not oscillate. The method consists in starting with a low gain value for driving a laser diode, increasing the gain value by small amounts until an oscillation detecting unit detects that the laser feedback system is oscillating. Then the gain value is reset to the previous value or a little bit more. Then the laser feedback system is again in a non-oscillating area with a suitable maximum gain value. This iteration is performed by a system consisting mainly of a laser diode, a photodiode for detecting the reflected light, and an oscillation detecting unit which controls a gain controller. This gain controller sets the gain on a multiplier which drives the laser driver for the laser diode.

    摘要： A system for reducing noise in a data recording/play-back device includes an optical system for scanning a recording medium and providing first and second polarization signals. The polarization signals are added to provide an added signal. The added signal is differentiated to provide a noise reduction signal. The polarization signals are substracted to provide a difference signal. The differentiated signal is substracted from the difference signal to provide a data signal having a substantially reduced noise level.

    摘要： A communication terminal device which can negate the need for troublesome switchovers and increase ease of use. In the device, a communication unit is connected to a client and carries out short distance wireless communication. An AP operation unit relays the transfer of data between the client and the connection destination thereof, on behalf of an access point. An electric field intensity acquisition unit measures the electric field intensity of a signal received from the access point. A client connection cancellation unit determines whether the device is within the communication area of the access point on the basis of the electric field intensity measured by the electric field intensity acquisition unit. If it is determined by the client connection cancellation unit that the device is within the communication area of the access point, an AP operation termination unit cancels the connection with the client in the AP operation unit.

    摘要： A double lumen-type catheter design which prevents damage to a child catheter and loosening of a stud valve of the double lumen-type catheter. A child catheter is housed inside a parent catheter so that it can freely slide, with the back end of the parent catheter joining with a front end of a Y-type connector with a branching path. The back end of the child catheter extends so that it passes through a back of the Y-type connector toward. A stud valve locks the back end of the child catheter at the back end of the Y-type connector. A cover covers the stud valve at the back end of the Y-type connector and the back end of the child catheter, and is attached so that it can be removed and replaced as needed.
