Patent JP-H06315201-A (JP)
Title: Driver for electric automobile
Inventor: MIZUTANI RYOJI
IPC: B60L3/00
Filed: 1993-04-27
Abstract: PURPOSE:To prevent unstabile control of a switching element even upon reduction of power supply voltage for a predrive circuit. CONSTITUTION:Transistors Tr1-Tr6 constituting an inverter 32 are turned OFF forcibly though a predrive circuit 38. When the power supply for the predrive circuit 38 though a DC/DC converter 46 is interrupted, a DC voltage appearing at an inverter 32 is passed through a DC/DC converter and fed, as a power supply voltage, to the predrive circuit 52. Consequently, even if the power supply for the predrive circuit 38 through the DC/DC converter 46 is interrupted, unstable control of the transistors Tr1-Tr6 is prevented thus preventing runaway due to noise. A contactor SW4 may be provided on the output side of the inverter 32.

Abstract: PROBLEM TO BE SOLVED: To obtain a stretchable composite sheet suitable for use as a side member by integrally constituting a non-woven fabric having a tensile stress of a specific value at the time of elongating in a transverse direction and an elastic sheet having stretchability of a specific value. SOLUTION: The non-woven fabric which is elongatable in at least its transverse direction and is >=100% in the elongation rate and >=100g/5cm in the tensile strength at the time of elongating 100% in the same direction and the elastic sheet having the stretchability of 400 to 800% in the elongation rate constitute a region for maintaining the substantial stretchability in the central part region of the diaper 1 where both are lightly joined or not joined. In the right and left end regions in the transverse direction thereof, both are thermally fused over the entire surface to constitute a region having substantially no stretchability. Both regions are formed as an integral region consisting of the non-woven fabric and the elastic sheet alone.  Both right and left end regions of the composite sheet forming the diaper 1 are thus the regions having no stretchability and, therefore, the joining with other members (side members 2) in these regions is stably and securely executed.
