Patent KR-810001822-B1 (KR)
Title: Process for the preparation of pwdered charcoal
Inventor: CHOI J
IPC: C10B53/02
Filed: 1980-03-11
Granted: 1981-11-16
Abstract: The method of preparing the powdered charcoal with tar from wood was described.  Charcoal was prepared by introducing the wooden material into a rotary kiln in which it was heated to a carbonizing temperature 800-1000≰C by the combustion of gas emitted by the carbonizing of previously inserted material in a rotating carbonizer.  The gas was intermixed for combustion with air also injected into the rotary kiln.  The air and gas were directed and controlled in the chamber in a manner that the wooden material was never exposed to sufficient oxygen to help free combustion.

Abstract: The scroll-type fluid machine has a stationary scroll and an orbiting scroll.  Each includes a disc-like end plate and a spiral wrap extending axially from one side of the end plate.  The wraps of the scroll members mesh with each other to define closed compression chambers.  The orbiting scroll is disposed between the end plate of the stationary scroll and the machine frame with back clearance.  The orbiting scroll is driven to make an orbiting movement w.r.t. the stationary scroll so that the compression chambers are progressively moved towards the center of the scroll while decreasing their volumes.

Title: Fibey optic amplifier
Inventor: SHAW HERBERT J
IPC: G02B6/26
Filed: 1984-11-24
Granted: 1994-08-12
Abstract: An amplifier for use with fiber optic systems comprises a neodymium YAG crystal (44, Figs. 9, 12, and 13) placed in series with a signal-carrying optical fiber (12b, 54). The ND:YAG crystal (44) is supplied by the optical fiber (12b, 54, 62) with both the signal to be amplified, and pumping illumination. The pumping illumination is coupled onto the optical fiber (12b, 54, 62) by a multiplexing coupler (10b, 50, 60) which is used to combine the signal to be amplified and illumination from a pumping illumination source (42) onto the single optical fiber (12b, 54, 62). The pumping illumination inverts the neodymium ions within the ND:YAG crystal (44). The signal to be amplified propagates through this crystal (44) to stimulate emission of coherent light from the neodymium ions, resulting in amplification of the signal. Because this arrangement permits the ND:YAG crystal (44) to be end- pumped with pumping illumination, and because the length of the ND:YAG crystal (44) may be substantially greater than the absorption length for the crystal (44) at the wavelength of the pumping illumination, virtually all of the pumping illumination may be absorbed within the ND:YAG crystal (44) and used for amplification of the signal carried by the optical fiber (12b, 54, 62).

Abstract: In the case of an optical pick-up device for reading a magneto-optical recording medium, depending on the direction of rotation of its polarisation plane, the light beam reflected by the recording medium is reflected onto a first photodetector or a second photodetector. The data signal is obtained from the difference between the photoelectric voltages of the two photodetectors. 
<??>With a novel recording medium on which data are stored by means of pits and in magnetic domains, in order to be able to read both types of data simultaneously, the data signal PS, which represents the data which are stored by means of the pits, is obtained from the sum signal of the two photoelectric voltages. The data signal MS, which represents the data contained in the magnetic domains, is obtained from the difference signal of the two photoelectric voltages. The data signal PS can also be obtained by the transilluminating method by means of a photodetector (24, 25) provided behind the recording medium (5). The data signal MS can likewise be obtained by the transilluminating method by means of a polariser (27) and two photodetectors (28, 29) provided behind the recording medium (5), by forming the difference between their output signals, whereas the data signal PS is obtained from the light reflected by the recording medium (5).

Title: Cutter plate precision working, especially of holes
Inventor: DIETER KRESS
IPC: B23B27/16
Filed: 1989-09-23
Granted: 1997-05-01
Abstract: A cutter plate is provided for precision working, especially of holes, which is constructed as a symmetrical polygon with at least four corners and has at least one main cutting edge and one auxiliary cutting edge, as well as a projection which begins at the chip run-off surface of the cutting edges, whose sides serve as chip-guiding steps and whose boundary lines circumscribe a symmetrical polygon, whose shape corresponds to that of the cutter plate, and has smaller dimensions than the latter, so that, starting from the corner regions of the polygon, the width of the chip run-off surfaces decreases. The cutter plate is distinguished by the fact that each chip run-off surface has a plane shape and is inclined in the direction of its longitudinal extension by an angle in such a way that the narrowest region is at the greatest height and is arranged to be above the neighboring chip run-off surface, so that it can be manufactured very simply and economically by a grinding procedure. In this way, a very high accuracy of dimensions can be achieved. With this cutter plate, an optimum flow of chips and hence a superior surface quality, can be achieved. The shape of the cutter plate is so simple that several different cutter plates can be manufactured easily at favorable cost for various application purposes.
