The inside of the  retort 2 is maintained at a prescribed degree of vaccum, and the work in the retort 2 is  heated up to near the welding temp. using a burner 10. On the other hand, electricity is connected to the heaters 14, 16 of upper and lower pressurizing bodies 13, 15 of the diffusion  welding device and when the temps. of the bodies 13, 15 rise to near the welding temp., the  carriage 8 is drawn out, and retort assemblies 1, 2, 3, 4, are moved onto the body 13, thence  an air release device 12 and the valve 4 are connected and the air releasing is started. After  the degreee of vacuum and the temp. attain a joining state, the body 15 is screwed down to  maintain the pressurizing force, whereby diffusion welding is carried out. The retort assemblies are carried out and are cooled. Hence, no stresses are generated between the work and  the pressurizng bodies.

Title: Controlling method for thyristor converter
Inventor: KINOSHITA SHIGENORI
IPC: H02M7/12
Filed: 1977-12-29
Abstract: PURPOSE: To suppress easily the AC higher harmonic of the primary winding of a transformer by giving a phase difference to the turn-on angle of a thyristor converter which supplies power to a load, connected to two groups of secondary windings or more of the transformer, operated simultaneously.  
     CONSTITUTION: In case of a thyristor system AC rolling stock, etc., an alternating current from the aerial conductor is inputted to the primary side of the transformer and several secondary windings such as the 1st group of secondary windings 2-1 to 2-4 and 2nd group of secondary windings 2-5 to 2-8 are connected to thyristor converters 3-1 and 3-2 composed of several thyristor rectifiers, whose outputs are supplied to DC motors 5-1 and 5-2. Controlling those two groups of rectifiers to turn on at turn-on angles of (α+Δα) and (α-Δα) smooths the primary current of the converter and reduces the higher harmonic contained, thereby reducing the induction fault of a communication circuit close to the aerial conductor. In this case, although a difference in DC output voltage mean value among thyristor converters is generated, an advance-delay phase is switched at the prescribed period, so that the output voltage can be averaged.

Filed: 1985-07-19
Abstract: PURPOSE:To simplify the circuit constitution by providing two capacitors which are charged and discharged alternately and using a single reference voltage circuit to switch this charging/discharging. CONSTITUTION:When the Q output of a flip flop 14 is in the low level, switching elements FETs 31, 42, and 10 are turned on and FETs 41, 32, 11 are turned off. Then, a charging current is flowed into a capacitor 51. The FET 10 takes out selectively the charging voltage of the capacitor 51 and compares it with one reference voltage, and the output level of the flip flop 14 is inverted when the charging voltage exceeds the reference voltage. As the result, switching elements FETs 41, 32, and 11 are turned on and FETs 31, 42, and 10 are turned off, and the electric charge of the capacitor 51 s discharged, and a capacitor 52 is charged. The FET 11 takes out selectively the charging voltage of the capacitor 52 and compares it with the same reference voltage, and the flip flop is inverted when the charging voltage exceeds the reference voltage. Hereafter, the similar operation is repeated.

Abstract: PURPOSE:To reduce the generation of crystal defects by a method wherein non-single crystal Si is single crystallized by projecting two laser spots, having different isolation direction and intensity, on the non-single crystal Si, to reduce crystal grain boundaries on the connected part of scanning. CONSTITUTION:A gauss type rectilinearly polarized laser beam 11 is passed through a 1/2-wavelength plate 12, and the beam 11 is converted into the beam 11a having different plane of polarization. Then, the beam 11a is passed through a crystal compound refraction plate 13, and it is converted into the beam 11b consisting of the two spots 14 and 15 having the different intensity and isolation direction. Then, a polysilicon layer 17 is recrystallized by scanningly projecting said spots 14 and 15 in the direction II as shown by the arrow in the diagram, and a single crystal Si layer 18 is obtained. According to this constitution, the beam 11b consists of the spot 14 and the spot 15 which is larger than the spot 14, and as they are arranged obliquely with each other, crystal is grown in the direction 16 when the beam is scanned in the direction II. Accordingly, the generation of a crystal boundary at the connecting part of the scanning is suppressed, and the single crystal having few crystal defects can be obtained.

Title: Operation control for steam generating device with accumulator
Inventor: FUJIMOTO SATORU
IPC: F01K1/08
Filed: 1990-06-20
Abstract: PURPOSE:To lessen the fluctuation of loading in a steam generating system, and thereby making the capacity of equipment for steam generation small by estimating the content of steam within an accumulator in time series, and thereby regulating the amount of steam to be generated by a steam generating device. CONSTITUTION:A conditioning valve 27 is fitted onto a feed pipe 17 by which steam from an exhaust hear boiler 6 is fed to the degassing equipment 16 through an accumulator 8, so that steam is conditioned based on control signals from a conditioning meter 28. Set signals are sent to the conditioning meter 28 from a computer 29. The increase/decrease of steam coming in/out of the accumulator 8 is computed in time series based on the amount of steam recovered/used. The proper amount of steam delivered from the accumulator at present is finally obtained, so that it is thereby outputted as the set value of the conditioning meter 28. By this constitution, the load fluctuation of steam is therefore made small, and a steam generating device for backing up can thereby be made smaller in size.

Filed: 1992-05-27
Abstract: PURPOSE:To efficiently utilize a fault information storing file in a maintenance center and to efficiently use a customer system line. CONSTITUTION:A fault detecting part 11 detects a fault generated in a computer system. A fault information collecting part 12 works fault information stored in an OS control part 10 to report information to be reported to a maintenance center system 2. A report judging part 13 judges whether the fault detected by the detecting part 11 should be automatically reported to the maintenance center system 2 or not. A transmitting part 14 transmits the report information worked by the collecting part 12 to the system 2 in accordance with the judged result of the judging part 13. Consequently, the automatic report of overlapped fault information to the center system 2 can be prevented.
