Title: Fast fourier transforming device
Inventor: SAKAMOTO TEIJIROU
IPC: G06F17/14
Filed: 1984-02-22
Abstract: PURPOSE:To obtain a fast Fourier transformation device capable of executing a complete saturation gain control free from overflow by inserting a shifter capable of executing a gain control between an arithmetic memory and a buffer memory for receiving real-time input data. CONSTITUTION:A saturation gain control circuit 6 monitors input data (a) during one CPI (coherent processing interval), detects the maximum value of the input data (a) and holds it. Then a control signal (b), that is, the output of the saturation gain control circuit 6, controls the input data (a) so that they will be shifted up within the range in which the maximum value will not overflow when input data (P) pass a shifter 7. On the other hand, the input data (a) are stored in a buffer memory 9, read out during the next CPI, and controlled by the shifter 7. At this time, since the control signal (b) to control the shifter 7 is generated by utilizing the maximum value of the input data (a), data will not overflow by the shifter 7.

Title: Dc arc furnace
Inventor: OKADA TAKEJI
IPC: H05B7/20
Filed: 1989-02-10
Abstract: PURPOSE:To enable the quick and easy restriking of arc without any contact between an electrode and a fusion metal by maintaining the electrically live condition of an SCR rectifier with an activation circuit even if an arc is out. CONSTITUTION:A switching control device 10 compares the current set value of a built-in setting unit with output from a current detector 9. In addition, when arc current is equal to or above a set value, the device 10 opens a contact 8 and closes the contact 8 when the current is less than the set value. An arc current control device 11 makes the phase control of an SCR rectifier 5 and controls the arc current. As the contact 8 is kept closed with the arc current equal to or below the predetermined value even when the arc is out, current flows continuously to the SCR rectifier 5 via an activation circuit 6, and voltage is kept applied between an electrode 2 and a furnace bottom electrode 4. Consequently, it becomes possible to restrike the arc without any contact of the electrode 2 with a fusion metal. When the current detector o detects current exceeding the predetermined value due to an increase in arc current, the device 10 opens the contact 8 and only the arc current flows to the rectifier 5.

IPC: B05B17/06
Filed: 1979-03-20
Abstract: PURPOSE: To increase the amount of stable atomized fuel by preventing surface deformation of stored liquid and by increasing the surface area of fuel column.  
     CONSTITUTION: Drain mechanism is usd to determine level of liquid reservoir tank 3 and ultrasonic resonators 11 are energized to form fuel columns 12. A distributor plate 15 is used to change the direction of fuel columns 12 at their ends toward horizontal way. Thus, liquid drops splashed from the edge of fuel columns 12 are deposited on the inner wall of atmomizing tank container 1 or a liquid drop recovery plate 16, and return as liquid flow to the reservoir 3 and auxiliary tanks 8a, 8b. Liquid drops splashed from middle or lower part of fuel columns 12 are similarly recovered by the recovery plate 16 and a liquid drop protection plate 17. As a result, all liquid drops splashed from the fuel column 12 are prevented from falling on the surface of the reservoir 3 and therefore causes no variation on the surface. Also, the surface area of fuel column 12 is increased by the distributor plate 15, thereby increasing the quantities of atomized fuel and thus fuel supply.
