IPC: C10L7/00
Filed: 1987-10-30
Abstract: PURPOSE:To provide a solid fuel capable of giving a high calorific value even when the size is small, which comprises methanol and a fuel having a calorific value of combustion higher than that of methanol. CONSTITUTION:A solid fuel is prepd. by mixing with or dissolving in methanol a fuel having a calorific value of combustion higher than that of methanol (e.g., isopropanol, butanol, acetone, benzene, dimethylformamide, gasoline, light oil, etc.), dissolving sodium stearate while being heated in the resultant mixture, and cooling the product for solidification. The heat generated from the fuel having a calorific value of combustion higher than that of methanol supplements the combustion heat of methanol, thereby imparting a high calorific value to the solid fuel. Also, a combustion heat of any desired magnification to that of the conventional solid fuel is obtd. by regulating the proportion of the fuel having a calorific value of combustion higher than that of methanol. Accordingly, it is possible to obtain a high calorific value of combustion even when the size of the solid fuel is small.

Title: Division circuit
Inventor: NOGUCHI TADAYUKI
IPC: G06F7/537
Filed: 1988-11-01
Abstract: PURPOSE:To realize the dividing operations with all number within a bit by using a low-order division circuit consisting of an addition circuit, an input/output selector circuit which decides the presence or absence of the digit shift of a divisor, a divisor shift circuit which performs the carry of the divisor, and an output control circuit which selects the arithmetic data based on the output of the input/output selector circuit. CONSTITUTION:A low-order division circuit 9 consists of an addition circuit which applies a subtraction-only method as its division arithmetic method. An input/output selector circuit 8 decides whether the digit shift should be carried out to a high-order bit or not based on the divisor value. A divisor shift circuit 7 performs the carry of the divisor, and an output control circuit 10 selects the data outputted through an arithmetic operation based on the output of the circuit 8. Then the presence or absence of the carry to the high-order positions and the number of carry bits are decided from the number given as a divisor. Then 1 is set up at the bit following a code bit and an arithmetic operation is possible with 1, i.e., the least divisor. Then the bits are matched with each other between the quotient and the residue of the arithmetic result. As a result, the division is possible with use of all numbers that are expressed in the number of bits of the divisor and the divisor is never limited.
