Patent EP-0319033-A2 (EP)
Inventor: NAKAMURA SHIGERU
IPC: G11B11/105
Filed: 1988-12-02
Abstract: According to the invention, an astigmatism is given to a light beam (1) which is focused onto a recording medium (202) and the reflected lights modulated by two kinds of pits (203, 204) formed on the recording medium surface are detected by a photo-detector (205). By focusing the light beam (1) having the astigmatism by a focusing lens (2), two focal lines (3, 4) which cross perpendicularly each other are formed at remote positions. A circle of least confusion (5) is formed at an al­most center between the focal lines (3, 4). Two kinds of pits or marks) (203, 204) are previously formed on the recording medium surface in order to apply the same modulation to the light beam (1) when the recording medium surface is located at a circle of least confusion position (5) and to apply differ­ent modulations to the light beam (1) when the recording me­dium surface is deviated from the circle of least confusion position(5). The reflected light which was reflected by the recording medium surface and passed through the focusing lens (2) is detected by the photo-detector. The signal modulated by at least one pit or mark of the two kinds of pits or marks is extracted from the outputs of the photo-detector (205). A fo­cus error detection signal in which a point when the recording medium surface is located at the circle of least confusion po­sition (5) between both of the focal lines (3, 4) is set to an in-focus (or zero point) is obtained from the phase or level of the extracted signal. According to the invention, since the focus error detection signal is obtained by using the total output of the photo-detector (205), it is sufficient to ar­range the photo-detector into the light beam of the reflected light which passed through the focusing lens (2) so as to de­tect the total reflection light. The focus error detection   signal which is hardly influenced by the deviation of the op­tical axis of the reflected light on the photo-detector sur­face and by the change in light intensity distribution can be derived. Thus, there is no need to match the optical axes of the center of the photo-detector (205) and the reflected light and the apparatus can also be easily assembled. Moreover, the focusing objective point corresponds to the circle of least confusion position (5) at which the cross section of the light beam (1) between two focal lines (3, 4) becomes a circle and is the zero point position of the focus error detection sig­nal. The focusing objective point can be autonomously ad­justed.

Abstract: A new type of polymeric microporous membrane has been synthesized which is distinguished by a highly-branched porespace morphology that is continuous and triply-periodic, and thus very precisely controlled and easily characterized. The membrane consists of a polymeric matrix containing pores of diameter on the order of 10 nm connected into a continuous pore network exhibiting long-range three-dimensional order. This long-range order is evidenced in small-angle X-ray scattering (SAXS) experiments by Bragg reflections that index to a triply-periodic space group, as well as in electron micrographs that match predictions from a theoretical model of the same space group and lattice parameter. The membrane combines three important features that have not been present simultaneously in any prior art membrane having pore diameters between 2 nm and 1 micron. First, the pores are identical in size and shape to a very high degree, and their size can be controlled in the synthesis. Second, the porespace is characterized by intricate branching and reconnections, with at least three pore throats meeting at a given pore body, this number (the coordination number) being the same for each pore body, and the porespace is isotropic in the cases where the space group is cubic. These two features allow accurately controlled sieving on the basis of particle size and shape, and provide highly accessible and precisely shaped pore bodies and surfaces for other applications such as catalysis, ion exchange, and the preparation of metal microstructures. And third, the membrane has a high porosity -- approximately 90 0 1 0  -- so that high rates of throughput can be reached. In addition, the membrane can be produced from certain microstructured fluid phases that are thermodynamic equilibrium states, so that it can be produced inexpensively and reliably.

Abstract: The invention is based on the object of developing a known mobile radio telephone in such a manner that data losses due to unintentional operation of operating and input elements, particularly by switching- off the radio telephone, are avoided. The object is achieved by the fact that a switching-off command by the microprocessor circuit (25) of the radio telephone (10) is only executed and that the mobile memory (18) can only be taken from the handset (11) when the following conditions are met. There must be no conversation taking place and all settings existing before the switching-off must have been transferred in the form of data into the mobile memory. During the later insertion of the mobile memory, the data stored in it are then transferred into a main memory (26) of the microprocessor circuit (25). The drawing shows a handset in perspective view and a radio transmitting and receiving set (12) connected thereto. <IMAGE>
