Filed: 1989-09-01
Abstract: PURPOSE:To easily take a measurement of height by inserting an inner rod into an outer rod slidably so that the inner rod projects from both end parts of the outer scale, and providing a scale which extends in the slide direction of the outer rod on the front surface of the inner rod. CONSTITUTION:The inner rod 3 is fitted in the outer rod 2 slidably so as to project from both its end parts. When the leveling rod 1 is stood and used, its standing direction is not limited and the leveling rod is turned over and optionally usable.

IPC: H02M3/335
Filed: 1986-09-29
Abstract: PURPOSE:To prevent burning of a main switch and others by providing error amplifiers for comparing and detecting a voltage generated at both ends of the main switch and an input voltage. CONSTITUTION:A DC-DC converter is composed of a reset diode 1, a main transformer 2 for power conversion, a main switch 3 for power MOSFET, rectifier diodes 4, 5 and others.
