Abstract: PROBLEM TO BE SOLVED: To provide a practical graphitization electric furnace for manufacturing graphite powder continuously by appropriately heating carbon powder at a high temperature without using any graphite electrode. SOLUTION: A carbon powder-charging port 4 and a carbon powder-collecting port 7 are provided at the center of the upper and lower portions of a furnace body 1, respectively, the appropriate halfway position between the charging port 4 and the collecting port 7 in the furnace body 1 is set to a graphitization region 8, and a plurality of sets of electrodes 9a and 9b are arranged in the furnace body 1 so that they oppose each other while sandwiching the region 8. When each set of electrodes 9a and 9b is energized while successively shifting timing, entire current flows through the region 8, current density in the region 8 is increased as compared with an outer periphery for increasing the amount of heat due to Joule heat.  On the other hand, an area near the furnace body 1 is retained at a sufficiently cooled state due to natural air cooling or the like, so that carbon powder 2 is heated to a high temperature locally only at the region 8 for graphitization.

IPC: H01S3/07
Filed: 1990-05-16
Abstract: PURPOSE:To simultaneously realize optical multiplexing/demultiplexing and optical amplification to suppress light absorption of active element ions in a part other than a taper part by doping at least two optical fibers out of plural optical fibers with active element ions which are different in classification and have the optical amplification capability. CONSTITUTION:Signal light having 1.55mum wavelength and signal light having 1.36mum wavelength are led to an optical fiber 1, and exciting light having 0.8mum wavelength is led to an optical fiber 2. In the part other than a taper part 3 of optical fiber parts, signal light and exciting light are shut in the core and are not affected by active element ions. In the taper part 3, exciting light propagated in the optical fiber 2 penetrates the clad of the optical fiber 2 and penetrates the fiber 1, and thereby, the intensity distribution of exciting light is spread to both optical fibers. Thus, Er ions and Nd ions in each clad are excited together, and energy goes to the inverted state.

Title: Overcurrent protecting circuit for semiconductor switch
Inventor: OKITA TAKAYOSHI
IPC: H02H7/12
Filed: 1990-05-15
Abstract: PURPOSE:To obtain an overcurrent protecting circuit having a high responding speed in a simple configuration by detecting the base current of a transistor, and turning OFF a MOSFET when the outputs exceeds a predetermined set value. CONSTITUTION:Since the base current of a transistor 1 is supplied from a secondary winding 3b of a feedback CT3, a collector current I and the base current are held at a predetermined ratio corresponding to a transformation ratio of the CT3. Accordingly, the base current is monitored by a current detector 11, so that the fact that the current I of the transistor 1 reaches an overcurrent level to be protected can be substantially detected. That is, if the base current exceeds a predetermined set value, a gate drive circuit 12 immediately sends a gate OFF signal to a gate terminal G1 to turn OFF a MOSFET 2 and sends a gate ON signal to a gate terminal G2 to turn ON a MOSFET 5 to interrupt the supply of the base current to the transistor 1 to turn OFF the transistor 1, thereby protecting it against overcurrent.

By making the heights of both the ends of the openings 16-19 provided at both the ends in the direction of air flow different from each other, twisted curved surfaces are formed in the louver-like cut-and-rised parts 20-24. As a result, inflowing air flows passing through the openings 16-19 flow along the twisted curved surfaces as indicated with the arrows 25. Consequently, the air flows flow so as to go in the rear of the heat transfer pipe 15 as indicated with the arrows 26, resulting in enabling to prevent the air flows from separating from the heat transfer pipe 15 and accordingly remarkably reducing the dead water region. In addition, vortices are generated by the air flows flowing along the twisted curved surfaces.

Abstract: PROBLEM TO BE SOLVED: To produce a duplicate of a computer file without giving any load to other jobs which are carried out in parallel to the file duplicating job by inquiring automatically about the new producing/updating state of the computer file in a short time and at a fixed interval. SOLUTION: An automatic duplicating device 1 inquires of a storage A 3 about the new producing/updating information on a computer file or receives this information via an API 2 and produces the duplication of a new producing/ updating file of the storage A 3 for a storage B 4. At the same time, the device 1 monitors the motion of a CUP 5 and produces a duplicate of the computer file when the load factor of the CPU 5 lowers continuously for a fixed time, discontinues temporarily the production of the file duplicate when the load factor of the CPU 5 rises and then restarts the production of the file duplicate when the load factor of the CPU 5 lowers continuously again for a fixed time. As a result, a user can produce a computer file with no special endeavor required and can duplicate the computer file without giving any load to the CPU 5.
