Title: Multiplying circuit for digital signal
Inventor: MUNESAWA ICHIJI
IPC: H04N5/20
Filed: 1983-07-04
Abstract: PURPOSE:To prevent the accumulation of errors of many multiplying circuits by detecting the maximum value of the control signal which controls the gain of a digital signal and adding the minimum until 1 to the output signal of a multiplier for output. CONSTITUTION:A digital signal is supplied from a terminal 1, and a gain control signal is supplied from a terminal 2. When both signals are set at the maximum value FF (hexadecimal), a detector 4 detects the maximum value FF of the control signal and supplies a high level to a switch 7. The switch 7 selects and delivers 1. For an adder 5, the multiplication result (FFXFF=FE01) of a multiplier 3 needs 16 bits and 01 is defined as an error as long as the result of multiplication is defined s 8 bits. However 1 is added to the FF of the multiplication result and therefore the FF is delivered. As a result, no addition is carried out with accumulation of errors for a multiplying circuit having its control input set at maximum 1 despite a multi-stage connection of such multiplying circuits.

Title: Discharge of solidified stored oil
Inventor: HATANO TOORU
IPC: C10G31/06
Filed: 1978-09-29
Abstract: PURPOSE: To prevent the environmental pollution by the charging and discharging of solidified oil in storage tank, and to improve the earthquake-resistance of the tank, by melting the crude or fuel oil stored in a tanl as solid by heaters placed to the bottom of the tank, and discharging the molten oil successively from the bottom.  
     CONSTITUTION: When the heaters 2 are heated, the solidified crude or fuel oil near the heaters is molten by the heat conduction. Since the solidified crude or fuel oil 4 has larger specific gravity than the molten oil, it decends to the direction of the white arrows. At the same time, the molten oil ascends to the direction of the small arrows, which increases the convection at the interface between the solid and the liquid, and strengthens the contact of the solidified oil to the surface of the heaters 2. The level of the oil is controlled by a thermometer, etc., and the molten oil is discharged through an outlet 5. To smoothen the decending of the solidified oil, the wall of the tank 1 may be furnished with heaters to melt the solidified oil 4.
