Title: Reluctance type motor juxtaposed with a plurality of armatures
Inventor: BAN ITSUKI
IPC: H02P6/08
Filed: 1989-09-28
Abstract: PURPOSE:To maintain counter torque at minimum level by performing storage and discharge, through a reverse-connected diode, of magnetic energy into/from an exciting coil with high speed. CONSTITUTION:Upon power interruption, magnetic energy stored in an exciting coil K does not return to DC power supply because of a counterflow blocking diode 18 but charges a capacitor 19 through diodes 21a, 21b thus bringing the voltage thereof to a high level. Consequently, the magnetic energy disappears quickly and the current level drops. Since transistors 20c, 20d have been conducted already, voltage of the capacitor 19 is applied onto an exciting coil M thus rising the exciting current sharply. By such arrangement, production of negative torque and counter torque can be prevented.

Title: Method of unifying temperature of layers in fluidized bed furnace and device therefor
Inventor: UOZUMI MASAHIRO
IPC: F23C10/00
Filed: 1985-11-08
Abstract: PURPOSE:To unify the temperatures of layers of respective cells by utilizing an endothermic effect in a desulfurization operation of a defurizing agent supplied for removing sulfur contents. CONSTITUTION:The fluidized bed furnace 1 is divided into a plurality of cells 2A-2D, and a fuel is fed into respective cells. When the furnace is put into an operative state, fluidized air from wind boxed 4A-4D is fed to divided cells 2A-2D, and a fuel is fed thereto through respective fuel supply ports 7A-7D. A desulfurizing agent is supplied from a desulfurizing agent supply port 8D to the cell 2D, for example, having high temperatures of layers. In the cell 2D a desulfurization reaction is caused and combustion heat in the fluidized bed 2 is absorbed by an endothermic operation upon this occasion. As a result, the temperature of layers of the cell is lowered, and draws near to the temperature of layers of the other cell, and the temperature of layers of the entire cell is unified. On the other hand, since desulfurizing agent supply ports for the cells 2A-2C of low layer temperature are not provided, the deusulfurizing agent is not directly supplied. However, the desulfurizing agent is diffused by fluidizing air, and is dispersed from the cell 2D to the other cells 2A-2C. therefore, a predetermined desulfurization is maintained in the fluidized bed.

Abstract: PURPOSE:To prevent an operating circuit substrate from being detached by mistake by a method wherein an operation signal discriminating circuit, a relay switch, a magnet, and an iron hook are provided on a circuit substrate. CONSTITUTION:An operation signal discriminating circuit 8 discriminates whether a circuit substrate 7 is in operation or not and then sends a signal to a relay switch 9. The relay switch 9 is turned 'ON' and supplies a power to a magnet 10, then the magnet 10 attracts an iron hook 11. In result, the engagement of a groove provided to a substrate detaching and attaching piece 5 with the hook 11 is retained so as to prevent the piece 5 from rotating in the direction shown by an arrow. When the circuit 8 discriminates that the circuit substrate 7 is out of operation, it makes the relay switch 9 'OFF', so that the magnet loses its magnetic force and the hook 11 falls by its own weight down to a pin 15 and is disengaged from the piece 5. The circuit substrate 7 can be detached only in the above-mentioned state. Therefore, the circuit substrate 7 in operation is not detached by mistake.
