Title: Uninterruptible power supply equipment
Inventor: NAKAJIMA KAZUHIRO
IPC: H02J9/06
Filed: 1988-02-29
Abstract: PURPOSE:To feed power stably from a battery to a load, by detecting the input voltage of a converter and providing a stop command to the converter when the input voltage of the converter exceeds over a predetermined value as well as when the power is interrupted, thereby stopping the operation of the converter. CONSTITUTION:When a power system is interrupted to increase voltage of an AC power source 1 thus increasing the output voltage from a rectifier 13, an overvoltage detection circuit 14B detects the increased voltage to produce a signal '1', which is fed through an OR gate 14C to the DC switch control circuit 11 in a rectifier control circuit 10. At this time, the rectifier control circuit 10 provides an operation stop command to a thyristor 2A rectifier 2A in similar manner as when the power is interrupted, and the DC switch control circuit 11 provides an ON command to a DC switch 4. Consequently, the thyristor 2A stops operation and the voltage is applied from a battery 6 onto an inverter 8 thus feeding power from a battery 6 to a load 9.

Abstract: PURPOSE:To make the falling of a frame material from a window main body hard by a method wherein the peripheral edge part of the window main body is integrally molded from both the front and the rear sides of the window main body by injecting another synthetic resin between a second cavity mold and the window main body, which is formed between a core mold and a first cavity mold and the frame material forming part of which is separated from the core mold. CONSTITUTION:After the positioning of a first cavity mold 6, a window main body 10 is molded. After that, the mold is opened and a mold plate 3 is turned through 180 degrees so as to bring a first core mold 4 to a position, which faces to a second cavity mold 7, in order to mold a frame material 12. At this time, after a molded window 20 is removed from a second core mold 5, the window main body 10 is molded by closing the first cavity 6. The molding of the frame material 12 is performed by injecting another resin 29 in a cavity 13, which is formed by mold closing after a gap 28 is made by separating the second core mold 5 from the window main body 10 so as to complete the window 20. At this time, the resin 29 also enters the peripheral edge part 28b and holes 30. Since the peripheral edge part of the window main body 10 is pinched from both its front and rear sides by the frame material 12, the frame material does not fall from the window main body.

Filed: 1979-04-21
Abstract: PURPOSE: To enhance the quality of a single crystal by separating or linking a plurality of atmospheric gas inflow pipes arranged coaxially with a rotary shaft for holding a seed crystal to adjust the flow rate of atmospheric gas.  
     CONSTITUTION: As growth of single crystal 10 proceeds and the top of crystal 10 approaches pulling and inflow hole 12', the opening area of hole 12' reduces gradually. Therefore, in the early stage of pulling of crystal 10 the inflow vol. of atmospheric gas from hole 12' is increased, and the inflow vol. of the gas from inflow hole 17' is decreased. As crystal 10 grows, the inflow vol. of the gas from hole 12' and that of the gas from hole 17' are controlled, and in the latter half stage of growth the inflow vol. of the gas from hole 17' is made larger than that of the gas from hole 12'. Accordingly, reaction product gas is well exhausted at all times, so the atmosphere in the vicinity of the melt surface and the solid-liq. interface is always maintained clean to enhance the quality of the grown crystal.
