Title: Iron core for three-phase transformer
Inventor: KONDO TAKESHI
IPC: H01F27/24
Filed: 1990-02-14
Abstract: PURPOSE:To reduce the curved intrusion of magnetic flux into a central leg part and to improve magnetic characteristics such as iron loss by using a 6.5% silicon steel plate whose magnetostriction is smaller than that of a directional silicon steel plate only for the central leg part. CONSTITUTION:A 6.5% silicon steel plate is used only for a central leg part 12. One-directional or highly oriented silicon steel plates which are used in conventional apparatuses are employed for other both side-leg parts 1 and 1 and upper and lower yoke parts 3 an 4. Since the 6.5% silicon steel plate of the central leg part 12 is nondirectional, it is not necessary to consider directivity. When the plate is formed in a strip shape, the plate can be readily cut. Meanwhile, a batten plate whose both ends are cut at 45 deg. is used for the side leg parts 1 and 1. A batten plate whose one side is cut at 45 deg. and other side is cut at 90 deg. is used for the upper and lower yoke parts 3 and 4. Thus the characteristics of the directional silicon steel plates are utilized. The iron core of this transformer is constituted by appropriately laminating the above described punched plates.

Filed: 1978-03-20
Abstract: PURPOSE: To provide a fuel supply port and an ignition heater in the same longitudinal section for shortening the ignition time, quickening the spreading of fire in the whole length of an evaporating part, and cleaning the exhaust gas.  
     CONSTITUTION: Liquid fuel is supplied from a fuel supply port 1, and sucked up by capillarity to be brought to the top of a porous evaporating part 2 composed of silica alumina and others. Evaporated gas is exhausted by the air given from  primary air perforations 3, and partly burned to supply evaporation heat to the  evaporating part 2. Air-fuel mixture is risen, and combustion air is supplied from  secondary air perforations 4 for forming a flame. An ignition heater 5 is provided  above the fuel supply port 1 to be positioned on a line A-A' in the evaporating  part 2. Consequently, the time of fire-spreading is shortened to cover the half of  the whole length, and its uneveness in both sides is removed to promote efficiency.  Thus, noxious effects given when a flame is grown up on one side only can be  removed, and the flame is steadily grown up toward both ends from the centre  without the pollution of exhaust gas.
