Patent EP-0512556-A2 (EP)
Inventor: WATANABE NOBUTAKA
IPC: H04B10/43
Filed: 1992-05-08
Abstract: In an optical transmitter and receiver device, a transmitter receives a transmitting data signal and drives a laser diode to make the laser diode emit an optical data signal representative of the transmitting data signal. The laser diode simultaneously emits a backward optical leakage signal. A photodiode is disposed at a rear side of the laser diode and detects the backward optical leakage signal as an optical monitoring signal to produce an electric monitoring signal. The transmitter receives the electrical monitoring signal to control an output power of the laser diode at a stabilized level. When the transmitter receives no transmitting data signal, the laser diode functions as an optical amplifier for an incoming optical data signal thereto and delivers an amplified optical data signal to the photodiode. The photodiode converts the amplified optical data signal to an electrical reception signal. A receiver receives and decides the electrical reception signal to produce a received data signal representative of the incoming optical data signal. Thus, the laser diode and the photodiode can be formed in a single optical module so that the optical transmitter and receiver can be reduced in size and cost.

Abstract: Die Erfindung bezieht sich auf eine elektrochemische Speicherzelle (1) auf der Basis von Natrium und Schwefel. Von Nachteil bei den bekannten Speicherzellen dieser Art ist die Tatsache, daß sie zu Batterien zusammengebaut, bei Ausfällen einzelner Speicherzellen größere Kapazitätsverluste der Batterie hervorrufen. Diese Nachteile werden dadurch vermieden, daß das Mengenverhältnis von Schwefel zu Natrium in Abhängigkeit von der Nennkapazität der Speicherzelle (1) so festgelegt ist, daß die Spannung am Ende der Nennentladung einen vorgegebenen Wert und das bei der Entladung gebildete Natriumpolysulfid eine definierte Zusammensetzung aufweisen. <IMAGE>

Abstract: A group of film cassettes individually comprise a rotary disk, a bar code on the disk having alternating spaces and bars which when optically detected can provide film-related information and a measure of the angular position of the disk, and eye detectable film exposure status indicia and a corresponding indicator one of which is on the disk and the other is fixed to align respective ones of the exposure status indicia and the indicator in accordance with the angular position of the disk. The bar code is visible substantially only to infrared radiation to make it essentially invisible to the human eye but to allow it to be optically detected with infrared radiation, and has at least one space and/or bar with the same location on the disk for each of the cassettes. The indicator or exposure status indicia on the disk is superimposed or integrated with the one space and/or bar to economize available space on the disk, and is optically indistinguishable in infrared radiation from the one space and/or bar to prevent its being optically detected with infrared radiation.

Abstract: This is a method for fabricating a structure useful in semiconductor circuitry. The method comprises: growing a germanium layer 28 directly or indirectly on a semiconductor substrate 20; and depositing a high-dielectric constant oxide 32 (e.g. a ferroelectric oxide) on the germanium layer. Preferably, the germanium layer is epitaxially grown on the semiconductor substrate. This is also a semiconductor structure, comprising: a semiconductor substrate; a germanium layer on the semiconductor substrate; and a high-dielectric constant oxide on the germanium layer. Preferably the germanium layer is single-crystal. Preferably the substrate is silicon and the germanium layer is less than about 1 nm thick or the substrate is gallium arsenide (in which case the thickness of the germanium layer is not as important). A second germanium layer 40 may be grown on top of the high-dielectric constant oxide and a conducting layer 42 (possibly epitaxial) grown on the second germanium layer. Preferably the high-dielectric constant oxide is a titanate, such as barium strontium titanate. When the high-dielectric constant oxide is a lead-containing titanate 34, a buffer layer of non-lead-containing titanate 32 is preferably utilized between the germanium layer and the lead-containing titanate.

Abstract: In an apparatus for determining the contents of a battery or accumulator (10), the inductive coupling provided by the battery or accumulator (10) between an excitation coil (20) and a sense coil (30) is measured. To improve the selectivity of the apparatus magnets (41, 42) are provided that generate a quasi-static magnetic field during a measurement. The quasi-static magnetic field saturates the iron in an ornamental jacket of the battery or accumulator (10) so that the inductive coupling between excitation coil (20) and sense coil (30) is almost completely determined by the interior of the battery or accumulator (10). The inductive coupling at different frequencies, with and without the quasi-static magnetic field, yields a reliable identification. The excitation coil (20) can be energised by a current source (21, 22, 23) generating an alternating current with constant amplitude. Thereby, the signal in the sense coil (30) is insensitive to the change in self-induction of the excitation coil (20) due to the presence or absence of a battery (10).

Abstract: A process for molding an article made of an inductive material is provided, wherein the inductive material is molded in a mold by means of high frequency induction heating caused by a high frequency magnetic field which is established by a high frequency induction coil surrounding the outer periphery of the mold. The process comprises the steps of: (a) supplying the inductive material continuously or intermittently from the top of the mold; (b) subjecting the inductive material in the mold to the high frequency induction heating to melt the same thereby to form a molten zone; and (c) moving the mold downwards relative to the high frequency magnetic field; the steps (a), (b) and (c) being done simultaneously to move the molten zone upwards from the bottom to the top of the mold, whereby the inductive material is once melted and then solidified to form a molded article. The inductive material may be an inductive metal or a composite matrial composed of an inductive metal and a ceramic material. The condition of the material in the mold may be monitored by a sensor and the lowering speed of the mold or the electric power for energizing the high frequency induction coil is controlled in response to the signal from the sensor. The mold may be vibrated to improve the production efficiency and the property of the molded article. Also provided is an apparatus for accomplishing the process described above.

Abstract: A method of recording (preserving) and reproducing an image is disclosed. The x and y axes are assumed on the plane of an original image, the z axis (density axis) is assumed to be perpendicular to the x and y axes, and a space defined by the x, y, and z axes is divided into rectangular solid cells. The volume ratio below a density distribution curved surface of the volume of each rectangular solid is recorded. Upon reproduction, the curved surface is reproduced based on the volume ratios of the rectangular solids which the density distribution curved surface crosses, and those of rectangular solids adjacent thereto. 
     In a four-dimensional Euclidean space defined by an image plane (x,y), a density or brightness D, and time or a frame f, an image is expressed by a solid in this space. This space is divided into four-dimensional rectangular solids, and an amount proportional to the volume of the solid in each rectangular solid is recorded or transmitted. Upon reproduction, the solid is reproduced based on the volume amounts of the rectangular solids and those of rectangular solids adjacent thereto, thereby reproducing a dynamic image.
