Title: Maximum detection receiver
Inventor: NISHIGUCHI KENICHI
IPC: H04B1/10
Filed: 1984-09-17
Abstract: PURPOSE:To detect an optimum radar which utilize the statistical property that a received signal has by inserting some kind of nonlinear converter based upon maximum likelihood estimation logic between a square-law detector and an integrator. CONSTITUTION:The receiver consists of an IF filter 2, square-law detector 3, nonlinear converter 6, integrator 7, etc. Then, a receive signal inputted from an input terminal 1 is passed through the IF filter 2 and squared by the square- law detector 3 to estimate the value of a parameter A. The valve A' of A which maximizes logarithmic likelihood is only found according to the maximum likelihood logic. Further, it is decided on the basis of the value A' whether there is a pulse train or not, so a preset threshold value A0 is only compared with A'. In this case, the value A' needs not be found at every time and the gradient of A0 obtained by substituting A0 in the logarithmic likelihood is only checked. Those operations are carried out by the converter 6 and integrator 7 and the sign of the output of the integrator 7 is only checked lastly, thereby deciding on whether there is a pulse train or not.

Abstract: PURPOSE:To obtain a large-core diameter porous cellulose in which pores larger than about 2mu are relatively homogeneously distributed, by freezing liquid drops of a cellulose solution and regenerating the cellulose after the solvent is removed by extraction or deprived of its solvency. CONSTITUTION:A cellulose solution is divided into liquid drops, and these drops are frozen by cooling to a temperature lower than the solidifying temperature. The solvent in the frozen drops is removed by extraction or deprived of its solvency to obtain the purpose porous particles. The pores of the porous cellulose particles should have a diameter above about 2mu, preferably, most of them should be larger than 5mu. When it is smaller than this value, the free movement of a fluid or a substance in the pores of the cellulose particles cannot be realized, and their use is limited.

IPC: G05F1/577
Filed: 1991-08-08
Abstract: PURPOSE:To suppress power consumption even if the average voltage of high voltage system is lowered and current consumption is maintained constant by providing a circuit for comparing the battery voltage with a set voltage for switching power supply and switching the power supply to a battery if the battery voltage is higher than the set voltage otherwise to a booster circuit. CONSTITUTION:When power supply voltage is limited to one dry battery(1.5V), for example, circuits operable with power supply voltage of 1V are connected with a low voltage system 6. Circuits requiring power supply voltage of 1.3V or above are connected with a high voltage system 8. A voltage detecting circuit 10 compares the battery voltage with an inner reference voltage of 1.3V and when the battery voltage is 1.3V or above, a battery 5 is connected through a switching circuit 7 with the high voltage system 8. In other words, when a new battery keeps its voltage between 1.6V-1.3V, direct driving with battery is carried out in order to reduce power consumption. When the battery voltage drops below 1.3V, the switching circuit 7 switches the power supply system so that the 1.5V output from a booster circuit is also employed as the power supply.
