Title: Image forming device
Inventor: FUKUDA MASAYUKI
IPC: G03G15/00
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To always form a stable image and to improve quality by providing an air curtain for preventing the mutual mixture of air on the side of a process cartridge and that on the side of a fixing device on a carrying path on which recording material is carried. SOLUTION: A duct 3 is allowed to pass in a recording material width direction to a side (side of a driving side plate 6) opposite to a fan 5 under an optical box 2, and it is allowed to pass to the upper surface of the box 2 on the side of the plate 6. By boring plural slots on a part of the base of the duct 3, a part of the air taken in from the fan 5 falls down from the slot so as to form the air curtain, and heat or vapor outgoing from the fixing device 4 is prevented from flowing to the side of the cartridge. As for the shape of the slot at a part of the base of the duct 3; the slot is formed so that its side of the fan 5 where wind pressure is high may be thin and its width may be larger as it goes away from the fan 5, whereby the flow of the air outgoing from the slot is kept constant in width, right and left, as shown by an arrow.  Furthermore, by making the slot in mesh shape, dust is prevented from advancing into the inner part of the device.

Title: Semiconductor memory circuit
Inventor: ISAKI TERUAKI
IPC: G11C19/00
Filed: 1990-12-27
Abstract: PURPOSE:To prevent the destruction of the data stored in a memory matrix by simultaneously writing data to a memory matrix circuit when the timing signal is received from a memory writing timing control circuit. CONSTITUTION:A shift register 14 for accumulating input data converts (S/P) the serially inputted data to parallel data, thereby accumulating the parallel data of a prescribed bit number (n bits). A timing forming circuit 15 forms the timing for integrating the (n) bits of the input data converted from the serial to the parallel data and writing the data into the memory matrix circuit 1 and forms the pulse for one time of writing in the n-bits by the write clock WCLK of an input terminal 9. The shift register 14 for accumulating input data protects the data with this system which integrates and writes the (n) bits in the memory matrix circuit 1. The accumulated data is thus prevented from being destroyed even if the write address outruns the lead address in the range within n-1 bits.
