Title: Stepladder
Inventor: SASAKI MITSURU
IPC: E04G5/02
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To improve workability by connecting two ladder parts to each other at one end so as to be operable/closable, and connecting steps by columns so that the side edges are alternately opened in the ladder parts. SOLUTION: A stepladder 1 is formed by connecting a pair of ladder parts 2 by the uppermost stage step 3, and in steps 5 of the ladders 2, the different side end parts 5a, 5b are alternately connected by columns 4 to open one side so that a pair of columns 4 are arranged on the lowest stage steps 5. Next, the engaging parts 7 are arranged in the opening side end parts 5a, 5b of the steps 5 and both end upper parts of the step 3, and a connecting member 8 is engaged between the lowest stage steps 5. At using time, two stepladders 1 are juxtaposed, and a scaffold plate is moved and placed in the width direction from the opening side on the steps 5 to be locked on the engaging parts 7. When necessary, strength is enhanced by connecting a support member between the scaffold plate-placed steps 3, 5 and the end parts 5a, 5b of the lower side steps 5.  Therefore, the scaffold plate can be easily arranged even in a narrow place, and the number of part items and assembling manhours can also be reduced.

Title: Snubber circuit
Inventor: OKATSUCHI CHIHIRO
IPC: H03K17/16
Filed: 1989-05-18
Abstract: PURPOSE:To decrease the current rating of circuit components by recovering part of snubber energy through a diode circuit when an ON-pulse width is narrow or at the moment of turning off, and consuming the snubber energy with an inserted resistor after a prescribed time of turning off. CONSTITUTION:With an IGBT 3 turned off, a one-shot multivibrator circuit 28 turns on a FET 23 via a pulse transformer 25 for a time, the current is not almost attenuated for this time, since the FET 23 is turned on, the current of a reactor 18 is attenuated by a time constant depending on a resistor 21, then the current does not flow continuously. When the pulse width is wide, the recovery of the snubber energy is finished while the FET 23 is turned on. Thus, the continuous flowing of the current of the reactor 16 through the diode of the snubber circuit is evaded, and the current capacity of the reactor 18 and the diodes 20, 15, 17 is decreased.
