Inventor: MURAI HIDESHI
IPC: H04B1/707
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To control the amplitude in an adaptive and simple process in a state that keeps a function that can exclude the interference of other users by limiting the amplitude of a part having a prescribed change pattern by a controller among those components of I and Q axes, whose diffusion are modulated by a diffusion modulator between a waveform shaping filter and the diffusion modulator. SOLUTION: A delay circuit 101 delays the transmitting data, whose diffusion is modulated by a diffusion modulator 12 by a degree equivalent to the number of chips necessary for a pattern detector 102 to detect a pattern and also by a degree equivalent to the time necessary for deciding the weight. The detector 102 detects a pattern that requires the limitation of amplitude, based on the pattern change of the said transmitting data modulated by modulator 12. A weight selector 103 gives the prescribed weight to the pattern that is detected by the detector 102. A multiplier 104 multiples the delay result of the circuit 101 by the weight result of the selector 103 and outputs this multiplication result to a waveform shaping filler 13.

Title: Sodium-sulfur cell
Inventor: MORI SADAO
IPC: H01M10/39
Filed: 1985-04-17
Abstract: PURPOSE:To enable to eliminate non-uniformity in cell reaction caused by the effect of gravity and to prevent the accompanying ineffective use of an active material, by making a porus electrically conductive material to have different electric resistances along the direction of the acceleration of gravity. CONSTITUTION:A positive electrode is made to have different values of electric conductivity at its upper part A and lower part B respectively. That is, the lower part B of the positive electrode includes more molten sulfur than the upper part A of the positive electrode due to the effect of gravity. This is because the molten sulfur fills the voids of the porus electrically conductive material and moves upward because of surface tension. This causes a bias to the branch of current at the onset, resulting lower current density in the upper part of the positive electrode and higher current density in the lower part of the positive electrode. As a result, the difference between x values of the upper and lower parts of the positive electrode approaches zero at the end of discharging, and sodium polysulfide with mole ratio of sulfur to sodium uniform over the entire positive electrode is obtained. In this state, the cell can discharge further and active material can be utilized effectively.

Abstract: PURPOSE:To eliminate a fear of crack due to shrinkage, by a method wherein a molding material obtained by compounding a specific low temperature curing agent and intermediate temperature curing agent each with unsaturated polyester is cured primarily at a normal temperature within a molding tool and the same is cured secondarily at an intermediate temperature or higher after demolding. CONSTITUTION:A molding material is prepared by compounding a low temperature curing agent acting upon unsaturated polyester resin at the normal temperature of 10-30 deg.C and an intermediate temperature curing agent acting upon the same at the intermediate temperature of 30-60 deg.C or higher with the same, in manufacture of the unsaturated polyester resin molded product such as a marble tone washing counter. After the molding material has been cured primarily at a normal temperature by casting the same into a molding tool, at molded material is demolded from the molding tool and cured secondarily at a temperature of the intermediate temperature or higher. High heating is not generated at the time of the primary cure within the molding tool 1, but generated after demolding from the molding tool 1. Therefore, there is neither fear of generating a crack on a washing bowl part 5 by a protrusion 7 for molding the bowl part of a bottom force 1a due to heat shrinkage nor generation of damage on the molding tool 1 due to heat.

Abstract: PURPOSE:To always store the level of the pilot signal in the memory and thus perform the AGC action with the level stored in the memory when the fault occurs. CONSTITUTION:The reception signals are branched by hydrid circuit 12 and then supplied to comparator 21 after detection. On the other hand, the output of counter 23 receives the D/A conversion to be supplied to the other side of comparator 21. Counter 23 performs the up- or down-count. In other words, the A/D conversion is carried out so that the counter shows the count value in accordance with the level fluctuation of the pilot signal of the reception signal. And now if the pilot signal is broken, comparator 16' works to close AND gate 24. As a result, the P- AGC signal at the level right before the break of the pilot signal can be applied to variable equalizer 11 from D/A converter 22.
