Title: Toner for electrophotography
Inventor: NAKANO TETSUYA
IPC: G03G9/087
Filed: 1992-09-11
Abstract: PURPOSE:To obtain a toner firmly fused on a fixing sheet even in super high speed copying by a high quality picture toner, excellent in off-set resistance and blocking resistance and free from fusing on a carrier, an electrifying blade or the like by controlling the average particle diameter of the toner particle to be below a specific value and using a specific releasing agent. CONSTITUTION:This toner has <=8mum average particle diameter and contains two kinds of a copolymer of propylene with olefin and polypropylene as a releasing agent. That is, as the crystallinity is decreased by copolymerizing propylene with olefin and the softening point of the toner is made lower than that in the case of using the conventional low molecular weight polypropylene, the toner is fused on the fixing sheet even at a low temp. And the polypropylene having 6000-10000 number average molecular weight is also used as the releasing agent. That is, the blocking resistance of the toner at a high temp. and high humidity is improved and the fusing of the toner on the carrier and the electrifying blade is prevented by using the releasing agent having high number average molecular weight.

Title: Nonvolatile random access semiconductor memory
Inventor: WATANABE TAKESHI
IPC: G11C16/02
Filed: 1988-09-27
Abstract: PURPOSE:To reduce the number of constituting elements of a nonvolatile semiconductor storage element to simplify the information storing and reading back operations to the memory by commonly connecting the control gate and source of the element with an output point and drain of the element for erase signals. CONSTITUTION:This memory is constituted of an IGFETs Mai for selecting address, nonvolatile semiconductor elements MCi and capacities Ci. When a write voltage Vw is changed from 0 V to 20 V during the period when information is stored from a RAM to each element MCi, each MCi operates to either collectively erase or do not erase the memory information held by the element MCi depending upon whether the memory information is 0V or 4V, since the potential difference between the drain and control gate of the MCi holding the information 4V does no reach an erasable threshold value. Therefore, the number of constituting elements is reduced and the information storing and reading back operations to the memory are simplified.

IPC: H04B10/07
Filed: 1990-09-13
Abstract: PURPOSE:To prevent production of momentary interruption even when a selection circuit is switched in any timing by using a frame synchronization circuit and a buffer circuit so as to synchronize phases of each frame on a transmission line of two reception signals obtained by duplicate optical transmission lines respectively an in-equipment frame location. CONSTITUTION:The relation of a frame phase of an input signal and an output signal of buffer circuits 6, 16 being a double buffer circuit is decided by frame synchronization circuits 5, 15 such that a frame of the output signal is equivalent to one preceding frame of the input signal. Thus, even when a phase difference due to bit shift is caused between reception signals 104, 114, when the difference is within one frame, the buffer circuits 6, 16 absorb the phase difference. Signals 106, 116 are inputted to a selection circuit 7 in the frame phase synchronization, a signal corresponding to the system changeover of systems 0, 1 is selected and outputted as a reception signal. Thus, no momentary interruption of a signal at system changeover by the selection circuit is not caused.
