Title: Time division multiple access transmitter
Inventor: VANNUCCI GIOVANNI
IPC: H04B1/04
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To reduce a low frequency signal component to be the cause of interference by selectively executing transmission in an interval being shorter than a whole time slot within one time slot and assigning a frequency except a transmission frequency which is assigned to a transmitter to a non-information carrier interference compensating signal by means of a prescribed compensating frequency. SOLUTION: A controller 705 controls a timing by which the non-modulation carrier wave output of an oscillator 703 changes the frequency into the frequency fc of an interference compensating signal. The burst of a modulated information carrier signal is amplified by an amplifier 706 and controlled by the controller 705 so as to be transmitted to an antenna 707. The interference compensating signal is outputted through the use of the oscillator 703 by the compensating frequency fc and modulated by a modulator 704 by the non- information carrier signal which is inputted to a selector 702 by a lead line 708. In place of it, the oscillator output of the compensating frequency fc can corresponds to a 'non-modulation' signal from an input lead line 709 to a selector 702 so as to execute pass-through without modulation by the modulator.

IPC: B60K20/02
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To certainly prevent the malfunction of a speed change gear without deteriorating operational characteristics, by canceling a positioning signal as a wrong signal even when the positioning signal is outputted even to the other position over a neutral position. SOLUTION: Even when a change lever 61 is swung to reverse position sides by the reaction of the energization force of a spring 116 and there is a DOWN or UP input after a change lever 61 is temporarily operated on an UP position side or a DOWN position side, an input signal by these reaction can be satisfactorily canceled. Therefore, wrong execution of speed change control can be favorably prevented and the malfunction of the transmission may not occur at all without deteriorating the operational characteristics of the change lever 61 due to strengthening of the energization force of a detent spring 106 and/or the engaging force of a recess 112.

Title: Method for reducing nitrogen oxide and reheating flue gas
Inventor: DENISU JIEI HERUFURITSUCHI
IPC: B01D53/56
Filed: 1992-06-03
Abstract: PURPOSE: To reduce nitrogen oxides and to reheat flue gas by heating a catalyst surface only by other procedures of heat transmission from flue gas and transmitting heat from the catalyst surface to flue gas. CONSTITUTION: A catalyst reduction reaction is performed down-stream of both a particle control process and desulfurization process. That is, the catalyst surface itself is placed just before the stack. As the result, the reduction reaction is taken place continuously both the particle control process and desulfurization process. The fresh flue gas is reheated at the same time by the reduced flue gas before discharging into the atmosphere. Therefore the sufficient catalytic reduction reaction is attained without maintaining the catalyst at high temp. by using gases at high temp. and regardless of the temp. of the flue gas. Consequently the catalyst at high temp. in the gas at low temp. can be brought equal and sefficient catalytic reduction to the catalyst at high temp. in the gas at high temp.

The scanning inspection points which are connected with the corresponding fixed inspection points are to be at L potential. Therefore, the number of such scanning inspection points is counted through scanning. After the completion of the scan, when the numbers of L and H coincide with those previously stored respectively, the fixed point is moved, and a similar operation is carried out. By this method, in case of 8,000 probe needles, inspection can be completed in 3.2 sec, so that the time needed for inspection can be redyced to approximately 1/5 of that by a conventional method.
