IPC: H02M7/21
Filed: 1995-04-14
Abstract: PURPOSE: To provide a switching power system which has a high efficiency by lessening a loss in a PNP transistor, a synchronous rectifying device. CONSTITUTION: One end ('a' point) of a choke coil L1 with its other end ('b' point) being connected to an input terminal 1 is grounded through a main current path of a switching transistor Q1. Furthermore, the emitter of a transistor Q2 which is constituted of a PNP transistor, a synchronous rectifying device, is connected to one end ('a' point) of the choke coil L1. The collector of the transistor Q2 is connected to an output terminal 2 and a base is connected to the other end ('b' point) of the choke coil 1 through a parallel circuit constituted of a resistor R3 for controlling base current and a capacitor C3.

Title: Furnace staying time determining method
Inventor: MASUDA TOSHIICHI
IPC: C21D1/52
Filed: 1978-09-19
Abstract: PURPOSE:To heat to the specified temperature with a minimum of fuel, without causing insufficient combustion, by determining the heating curve when the object sensible heat is larger than the balance of the charge heat minus loss heat on the basis of the value at such time, when heating the object in a heating furnace. CONSTITUTION:When a heating furnace is divided into several bands, the furnace staying time on the whole is distributed into each band. In a certain band, when the heating object sensible heat Q2 is smaller than the balance of the charge heat Q1 minus loss heat Q3, the temperature rise curve of the heating object is determined from the total heat absorption rate. In other band, when Q2 is larger than the remainder of Q1 minus Q3, the product of the difference of Q1 and Q3 and the furnace staying time in that band is regarded as the object sensible heat increment to determine the heating curve of the object. The temperature of the object at the furnace outlet may be determined from this heating curve. By prolonging the furnace staying time gradually, the furnace staying time at the point where the temperature of the object at the furnace outlet reaches the intended heating temperature is the most efficient heating furnace staying time.
