Title: Method of laying communication cable
Inventor: HASEBE HIDEJI
IPC: G02B6/44
Filed: 1989-10-13
Abstract: PURPOSE:To facilitate laying of a communication cable and a sub-duct and prevent power cables from damaging by simultaneously inserting the sub-duct and a cable-passing rod into a piping simultaneously with insertion of a cable- passing rod. CONSTITUTION:When the end of a sub-duct 1 is inserted into the space in a piping 7 in which power cables 8 have already been inserted, the sub-duct 1 is moved forward in the piping 7 by guiding with a guide 5 at the end of a cable-passing rod 3. Since the sub-duct 1 is supported from the inside with the cable-passing rod 3 inserted thereinto, the sub-duct 1 is not broken in the piping 7 and can be smoothly inserted into the piping 7. When the end of the cable-passing rod 3 is thrust out of the piping 7, the guide 5 is removed from the thrust-out end of the cable-passing rod 3, an end of a communication cable 2 is connected to the end, and the communication cable 2 is drawn into the sub-duct 1 while the cable-passing rod 3 is pulled out in the opposite direction. Thereby the laying efficiency improves.

Inventor: HOSAKA KAZUYOSHI
IPC: H02M7/493
Filed: 1989-10-12
Abstract: PURPOSE:To suppress transverse flow inclusive of not only fundamental waves but also higher harmonics by seeking the deviation between reference voltage wave form common to each converter and individual voltage waveform by means of a comparison means, and further seeking the deviation between the average value of each inverter and individual voltage waveform, and giving it to the comparison means as a correction signal. CONSTITUTION:Due to the control error of individual inverters, difference occurs in each inverter output voltage. Thereupon, an average value operating circuit 3 is provided, and the output voltages of three inverters 10, 20 and 30 are input, and these average value is operated. Thereupon, the inverter No.1 operates the deviation between the output voltage and the voltage average value in a voltage deviation arithmetic unit 17, and gives the operation results to a comparator 16 as a correction signal. The inverter No.2 and the inverter No.3 are equipped with voltage deviation arithmetic units 27 and 37, respectively, and give correction signals, so the difference in output voltage of each inverter is made almost zero.

Title: Bellowslike container
Inventor: NARA TOSHIOMI
IPC: B65D21/08
Filed: 1994-09-26
Abstract: PURPOSE: To easily suck and discharge contents such as liquid by a change in pressure at a bellowslike container part, in particular to fill liquid or the like without spilling by providing the bellowslike container part on an end of a hollow cylinder and providing a lid at an opening at the other end. CONSTITUTION: In use, while a bellowslike container part 1 is contracted, an opening 3 of a container is inserted into liquid or the like and then contraction of the part 1 is released, thereby sucking the liquid into a hollow cylinder 2 due to a negative pressure generated in the container part 1. Thus an operation for putting the liquid or the like into the container can be safely performed without spilling the liquid or the like. After the liquid or the like has been thus put in the container part 1, a lid 4 is put over the opening 3 to have the container closed. Then in taking out contents, the lid 4 is removed from the opening 3, and the bellowslike container part 1 is pressed, thereby discharging the liquid or the like put in the hollow cylinder 2 and the bellowslike container part 1 from the opening 3.
