Title: Decarburization and annealing method for directional electromagnetic steel plate
Inventor: IWAYAMA KENZOU
IPC: C21D8/12
Filed: 1978-06-09
Abstract: PURPOSE: To obtain a surface behavior assuring high megnetism and high covering chacteristic by the procedure in which the decarburization process of the decarburization and annealing process for directional electromagnetic steel plate is divided into the former half and the latter half and the oxidative atmosphere of each is differentiated.  
     CONSTITUTION: In the decarburization and annealing process for directional electromagnetic steel plate, the decarburization process is divided into the former half process and the latter half process. In the former half process, the conventional decarburization method is used or heating is made under the condition of a decarburization-impossible atmosphere, or an oxidation degree of more than 0.15, because the oxidation degree of the conventional method is great, and also in the latter half process, heating is made under the condition of an oxidation degree lower than that of the former half process, or an oxidation degree of less than 0.75. Thus, it is possible to obtain a surface behavior enabling both the magnetic and covering characteristics of the directional electromagnetic steel plate to be improved.

Title: Locating system for power transmission line fault point utilizing artificial satellite
Inventor: OOHIRA TAKESHI
IPC: H02H3/28
Filed: 1988-03-24
Abstract: PURPOSE:To obtain high-accuracy locating ability by using timepieces installed individually in a master and a slave station which are synchronized with a timing signal from the artificial satellite and measuring and comparing the arrival time of a surge pulse generated owing to the fault of a power transmission line. CONSTITUTION:Surge detecting circuits 12 of master and slave stations perform level conversion so that an extremely small current circuit can receive a high-voltage surge signal generated owing to the rupture of the power transmission line. The GPS receivers 14 of both stations which synchronize with the timing signal from the satellite send cycle pulses of 10-10<2>nsec and a reset signal of 1Hz to a time counter 16. Consequently, the time counter/time base 16 is initialized at intervals of 1sec to convert the cycle pulses of 10-10<2>nsec into a digital signal of binary codes, etc. The slave station transfers this digitized signal to the master station through a modem 18 and a communication line. The processor controller 20 of the master station compares signals converted into digital values by counters 16 of both station to calculate the distance to the rupture point on the power transmission line, thereby sending information to an output device (CRT, etc.) 22.

Abstract: PURPOSE:To easily change the size of a MOS transistor by a method wherein the width of an impurity diffusion layer constituting a drain and a source for the MOS transistor is changed in the width direction of a gate electrode. CONSTITUTION:A P-type diffusion layer 2 is formed on one side of a gate signal interconnection 1 formed on a substrate; an N-type diffusion layer 3 is formed on the other side. The P-type diffusion layer is formed so as to be narrower toward one direction; the N-type diffusion layer 3 is formed so as to be narrower toward the other direction. For example, when an increase in the transistor size of an N-channel transistor 14 is forced, the position of a gate electrode 12 is changed to a position indicated by a chain line from a position indicated by a solid line; then, a gate width W1 formed in 10mum is changed to a gate width W2 and is formed in 20mum. Thereby, the transistor size is increased. When a simulation is executed again based on such a change, a desired operation characteristic can be obtained. Consequently, the transistor size can be changed easily.

Abstract: PURPOSE:To reduce a draw-out tensile force applied to an optical cable and to prevent the optical cable from being damaged and broken by unwinding the optical cable from a bobbin and a tension member from another bobbin, and applying the tension member with a tensile force for revolving the bobbin. CONSTITUTION:The 1st bobbin 31 is rotatable relatively to a shaft 28 and engages the shaft 28 frictionally through a brake pad 32. The frictional force is adjusted properly and then when the draw-out tension to the optical cable 13 reaches a constant limit, the bobbin 32 slips on the shaft 28. Even when there is no slip between the bobbin 31 and shaft 28, a tensile force nearly a half as large as the tensile force which revolves the bobbins 31 and 34 is applied to the tension member 14 and when there is a slip, more than a half of the tensile force is applied to the tension member 14. Consequently, the draw-out tensile force applied to the optical cable 13 is reduced and never exceeds the constant limit, so the optical cable 13 is prevented from being damaged and broken.
