Title: Parallel type pulse insertion circuit
Inventor: FUJIMOTO HISANOBU
IPC: H04J3/06
Filed: 1988-03-25
Abstract: PURPOSE:To insert a pulse in an economical constitution by converting data into parallel data, making them into low speed data and inserting the pulse of one bit into an objective position. CONSTITUTION:Parallel data obtained by converting serial input data into parallel are written into a parallel type elastic memory 1, and data are read in accordance with a read clock signal. Parallel data which have been read and either data in said data are delayed by one bit by a delay circuit 2. A control part 4 controls a selection switching part 3 so as to generate one bit struggling in accordance with a pulse insertion request, and the pulse insertion part 5 inserts the pulse. Consequently, a C-MOS circuit which attains the operation of 40Mb/s can realize insertion by conducting a parallel processing even if serial input data are at the speed of 80Mb/s, for example. Thus, the pulse can be inserted into high speed data with economical constitution.

Title: Generating method of reference signal for evaluating difference of content of nonvolatile memory cell and generating circuit thereof
Inventor: CAMPARDO GIOVANNI
IPC: G11C17/00
Filed: 1995-03-28
Abstract: PURPOSE: To maintain the precision of a virgin cell for a long period and improve the reliability of the circuit by using the virgin cell which has characteristics shifted by a voltage shifter. CONSTITUTION: A cell and virgin cells 12 and 13 have gate-source voltages lower than a source voltage through voltage shifters 14 and 15 and their characteristics depend upon an operating load. In read mode, a logical signal R is low and a logical signal V is high, so switches 21, 26, 29, 33, and 40 are closed and a switch 42 is opened. When the source voltage is lower than 2.3V as the threshold voltage of the cells 12 and 13, the cells 11, 12, and 13 are turned off. When the source voltage exceeds it, the cells 12 and 13 turn on, but their characteristics become smaller than a logical slope because of the presence of the load.  The cell 11 is off between 2.3V and the source voltage and then a current flows to neither a load transistor 18 nor a mirror transistor 23; and only the cell 12 has a high resistance value and a current is made to flow through a load transistor 30 for supply current limitation.

Abstract: PURPOSE:To obtain a nonsintered nickel positive electrode having no peeling off of active material and good conductivity by forming a carbon layer comprising colloidal carbon on the surface of a nickel positive plate. CONSTITUTION:A paste-like active material mainly comprising nickel hydroxide is filled in a substrate made of spongy metal or fibrous metal having three dimensional continuous structure, and dried and pressed to obtain a positive plate.

Since the carbon layer is good conductor, even in high rate discharge less than tree times of the capacity, discharge performance equal to a sintered plate can be obtained. Therefore, sintering process can be eliminated.
