Title: Reduction length trace back
Inventor: DEIBUITSUDO MAAKU BUREIKAA
IPC: H03M13/41
Filed: 1994-12-21
Abstract: PURPOSE: To obtain a decoding symbol by tracing a path in every nook and corner in one row of a storage registers containing surviving branch data. CONSTITUTION: In a communication system which traces a path by going upstream the trellis of individual state information and contains a Viterbi decoder 154, a traceback unit 36 determines a decoding symbol. A matrix of surviving branch data is stored in an array of registers 28. Operating the communication system includes initiating a first traceback from a storage register in a first symbol instant, and the traceback determines a fist decoding symbol by tracing the path by going upstream the trellis by a prescribed number of first symbol instants. The traceback length is changed and another traceback is executed. This process is repeated until all remaining final decoding symbols are decoded.

Title: Semiconductor laser exposure recorder
Inventor: SHIRAIWA KEISHIN
IPC: B41J2/44
Filed: 1990-11-26
Abstract: PURPOSE:To minimize a load on a device to improve an efficiency by a method wherein a resolving power and the number of gradation steps per dot at the time of exposure recording are specified for conducting a recording control. CONSTITUTION:A visual resolution limit and a gradation discriminating capability from a distance of distinct vision are generally known to be 508 dot/inch and 256 gradation steps, respectively. However, these values are maximum thresholds independent of each other, and it is considered that there is no need for meeting the above requirements at the same time. As apparently shown in a figure, where a resolving power is 600 dot/inch or more and a gradation step number is 48 or more, an image quality cannot be improved to a great extent if the resiolving power and the gradation step number are further increased. Therefore, when a resolving power is at least 500 dot/inch and a gradation step number per dot is at least 32 at the time of exposure recording, a high image quality can be obtained with relatively small gradation step number and low resolving power. Therefore, a load on hardware can be reduced, and a recorder of a small-scale and low-cost construction can be obtained.

Title: Data-recording controlling system
Inventor: ICHIHARA MASAHIRO
IPC: G11B19/02
Filed: 1990-11-22
Abstract: PURPOSE:To improve the response performance in data recording to a large extent by holding the phase difference of the rotary angles of the recording media of a plurality of magnetic disk memory devices at the appropriate value, and recording the value into the recording medium which has reached at first in the vicinity of the rotary angle to be recorded when supplied data are written. CONSTITUTION:When the output of a rotary angle counter 22 or 23 for measuring the rotary angle of either recording medium of disk devices 10 and 11 agrees with an expected value, a coincidence signal is sent into sub-controllers 20 or 21 of the disk device whose value has agreed at first. The sending of the coincidence signal to the other sub-controller is suppressed. The sub-controller which has detected the coincidence signal sequentially reads the identifiers of the records. The identifiers are collated with the identifying data of the record. The operation is continued until the identifiers agree with the data. When they agree, the sub-controller 20 receives the data A of the supplied data 200 from a CPU 52 through a input-output transfer part 50, a gate 51 and a data buffer 30. The data are recorded in the data part of the record 1 of a record medium surface 100 and the data part of the record 2 following the record 1. Thus, the writing input/output response performance can be improved.

Abstract: PROBLEM TO BE SOLVED: To efficiently and easily recover the rare earth elements of high purity by roasting in a chlorine atmosphere pulverized metallic materials containing rare earth elements and iron at the temperature at which the rare earth chloride is remained and iron chloride is evaporated to easily separate iron. SOLUTION: Pulverized metallic materials containing rare earth elements and iron are roasted in the gaseous chlorine to change the contained rare earth components and iron into chlorides. The roasting in the gaseous chlorine is achieved in the temperature range where the generated rare earth chloride is remained and iron chloride is evaporated. The contained iron is changed mainly into iron (III) chloride, and a part thereof is changed into iron (II) chloride and evaporated. The roasting temperature is preferably between 320 deg.C and 800 deg.C. The roasting in the gaseous chlorine is completed targeting the stage where no gas is generated, and after completion, the chlorine gas is stopped, the furnace temperature is dropped, and cooled down to the room temperature, and the roasting residue is taken out.  Then, the rare earth elements can easily be recovered by leaching the rare earth elements from the roasting residue with water or acid.
