Title: Read-only fixed memory and multiplying method using this read-only fixed memory
Inventor: MARUOKA TAKAYA
IPC: G06F7/508
Filed: 1983-03-18
Abstract: PURPOSE:To attain multiplication in a short arithmetic processing time by preparing a ROM specified at the addresses by 8-bit binary data and stored the multiplied value of numbers indicated by high-order 4 bits and low-order 4 bits respectively, and executing multiplication by using said ROM and two registers. CONSTITUTION:A multiplicand P and a multiplier Q which are indicated as 8-bit binary numbers respectively are divided into the parts A, B of the multiplicand P and the parts C, D of the multiplier Q which are indicated as 4-bit data respectively. The multiplied values of all combinations of these 4-bit binary data A, B; C, D are found out. In case of BXD for instance, respective bits of the divided part B consisting of 4- bit binary data are inputted to the address specification input ports AD7-AD4 of the ROM from the upper bit successively and respective bits of the divided part D consisting of 4-bit binary data are inputted to the address specification input ports AD3-AD0 of said ROM from the upper bit successively to obtain the multiplied values from the output ports C7-C0. In the same manner, respective multiplied values of AXD, BXC and AXC are found out. On the basis of BXD, AXD and BXC are shifted by 4 bits respectively. AXC is shifted by 8 bits and these shifted values are added to obtain the multiplied value.

Abstract: PURPOSE: To improve reliability of a cooling water fluid pump of a blast furnace or the similar in an emergency by connecting the pump to a flywheel which is  rotated by an engine linked to a motor or a clutch.  
     CONSTITUTION: When a motor 1 cannot drive a pump 2 due to an interruption of power supply or other reasons, energy accumulated in a flywheel 3 during normal operation is released to go on driving the pump 2. On power failure, a solenoid valve 8 works to open a main pipe 14, which allows operating oil to run from an oil pump 7 through a pressure regulating valve 9 for working a clutch 4. After a few seconds passed from start of the clutch 4, the flywheel 3 has the engine 5 ignite and run. It is not until energy off from the flywheel 3 is boosted enough to the level required for driving the pump 2 that the engine 5 is loaded. This provides smooth starting and operation of the pump.
