Patent JP-S59171315-A (JP)
Title: Analog-digital converter
Inventor: FUJITA TSUNEO
IPC: H03M1/36
Filed: 1983-03-18
Abstract: PURPOSE:To obtain a circuit with simple constitution constituted only with an MOS transistor(TR) structure by setting an input threshold value of a positive logical input terminal lower than an input threshold value of a negative logical input terminal or setting the input threshold value of the positive logical input terminal higher than the input threshold value of the negative logical input terminal. CONSTITUTION:The 1st code converter 15 selects an output of a position detecting logical circuit 50 in duplication by setting the input threshold value of the positive logical input logic gates 401, 411, 421, 431, 441, 451, 461, 471 constituting the position detection logical circuit 50 relatively lower than the input threshold value of the negative logical input logic gates 402, 412, 432, 442, 452 and 462. A low-order code of a gray code, however, is outputted at all times when two adjacent codes are overlapped and is not changed to other codes. Even if an output of a comparator is brought to any intermediate level ''X'', the output is changed normally from an output code to the next output code in this way.

IPC: C10N50/08
Filed: 1979-04-13
Abstract: PURPOSE:To obtain a lubricating composition having good workability and good oily surface formability resulting from the exudation of oil, by solidifying a mixture of a polyethylene of a superhigh-or low-molecular weight and a lubricating grease by heating. CONSTITUTION:A mixture, consisting of 5-99wt% lubricating grease (A) and 95-1wt% superhigh-molecular polyethylene of an average molecular weight of 1X 1<6>-5X10<6>, is heated for solidification. In this case, a low-mlecular polyethylene of an average molecular weight of 2X10<3>-1X10<5> may be used in the place of said superhigh-molecular polyethylene, but the rigidity and oil retention of the gel composition using the low-molecular polyethylene are slightly inferior to those of the gel composition using the superhigh-molecular polyethylene. Also, in order to slow down the speed of oil exudation from from the lubicating composition, a wax or a mixture of the wax and a lubricating oil, which is solid at ordinary temperature, may be added to the lubricating composition.

Filed: 1983-03-23
Abstract: PURPOSE:To reduce the variance of a current and a voltage and to reduce noise by shifting the phase of difference type of refresh RAS signal and therefore shifting the generation time of a peak current when a memory IC is actuated. CONSTITUTION:A refresh RAS signal 5 is produced from an RAS signal generating circuit 3 when a refresh action is executed. In this case, the phase is shifted between phase control signal 6 and 7 of the RAS signal sent from a phase control circuit 4. Therefore RAS signals 8 and 9 are delivered to a memory IC with a phase shift. As a result, a time shift is given to the refresh start between an upper half 10 and a lower half 11 of the memory IC. Furthermore a position shift is also given to the peak current between the parts 10 and 11.
