Title: Ring burner
Inventor: OBARA TOSHIMICHI
IPC: F23D14/06
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To enable a large turn-down ratio to be applied by a method wherein the internal space of a hollow ring burner is divided by a partitioning plate into a small chamber and a large chamber, while both chambers are provided with flame ports in rows and fuel is supplied through mixing pipes provided-in respective chambers. SOLUTION: A hollow ring burner is constituted of a main body 9, a lid body 10 and a ceiling plate 11 while the lid body 10 itself constitutes a partitioning plate 1, dividing the inner space of the burner into up-and-down. Flame ports 5 are formed of a multitude of cut-in grooves, indented from the lower end rim of the outer wall of the lid body 10. However, the flame ports 5 are formed so that the sectional area thereof are narrowed gradually toward the outsides thereof. According to this method, the passing resistance of the part of the flame ports 5 is reduced whereby the sucking amount of primary air with respect to the amount of injection of fuel gas in a mixing tube 7 is increased, thereby permitting the increase of combustion amount of the burner in accordance with the increased amount.  On the other hand, when flames are choked so as to be small flames, combustion can be adjusted by only a cock 13 for small flame while closing a main cock 12 whereby a sufficiently large turn-down ration can be obtained.

Title: Hollow plate-like conductor laminated superconducting magnet
Inventor: MAKI NAOKI
IPC: H01F6/02
Filed: 1995-02-28
Abstract: PURPOSE: To prevent quenching from occurring in a conductor-type superconducting magnet by a method wherein a large number of hollow plate- like superconductors are piled up into a multi short-circuit superconductor group. CONSTITUTION: A large number of hollow plate-like superconductors 1 are piled up into a multi short-circuit superconductor group 2. The multi short-circuit superconductor group 2 is composed of a large number of short-circuit superconductor plates 1 each of thickness 1mm or so. When a current is applied to an exciting coil 3 from an outer power supply 4, a current is inductively introduced into the multi short-circuit superconductor group 2, the multi short-circuit superconductor group 2 serves as a superconducting magnet when it is made to operate in a permanent current mode. Even if quenching occurs in a part of the superconductor group 2, the other residual superconductors carry an operating current provisionally, so that quenching is prevented from occurring in the superconductor group 2 as a superconducting magnet.

Filed: 1991-03-06
Abstract: PURPOSE:To obtain more remarkable effect of miniaturization of the chip size at the time of using more segment current sources by using an output switch circuit and a dummy output switch circuit consisting of MOS transistors TRs having the same polarity. CONSTITUTION:An output switch circuit SW of a current segment circuit is connected between a segment current output node Z and the current input node of a reference current source I.
