Title: Multiple precision high radix nonrecurrsive type divider
Inventor: IKEDA MASAYUKI
IPC: G06F7/52
Filed: 1985-04-30
Abstract: PURPOSE:To attain division with a multiple precision with a divider having a low accuracy by setting byte width + 1 digit of a divisor to a partial remainder register from a dividend with high accuracy at first and a low-order n-bit succeeding in the dividend to the least significant n-bit of the partial remainder register. CONSTITUTION:A divisor of M-byte is set to a register 1 and a dividend N (N>M) is set to a multi-precision remainder register 4'. When the divisor is inputted to a multiple generating circuit 2, a partial quotient forecast signal (m) is received from a partial quotient forecast circuit 3 and the divisor is produced based on a radix, one of them is selected and mXD is inputted to a carry adder 5. When M-byte + n-bit are extracted from the register 4' and set, the partial remainder register 4 outputs a partial remainder Pn+1. The effective digit (high-order M-byte) of the partial remainder is fed back to the high- order digit of the register 4 and the next n-bit of the register 4' is extracted and inserted to the least significant digit (n-bit) and added with the mXD at the carry adder 5 to obtain the next partial remainder.

Filed: 1990-04-06
Abstract: PURPOSE:To prevent the blowoff of toner which rides the air blown off from a vent part toward the outside by providing the vent part to the outside at the part of a developer storing area and applying a semipermeable film to the vent part. CONSTITUTION:The semipermeable film 85 is applied to the vent part provided at the part of the developer storing area of a developing device. Therefore, it transmits only air and does not transmits toner. By selecting the total aperture area of the event part, the resistance thereof is made much smaller than ventilation resistance through a seal part 25 around the developing roller 11 of the developing device. Thus, the developing device is attached/detached or replaced singly or in cartridge unit with others. In the case that inside air is blown off because of deformation that content volume becomes small in handling when the device is carried, the toner riding the air blown off from the vent part is captured by the film 85 and the blowoff of the toner toward the outside is prevented.
