Title: Method for controlling flow rate of ammonia in waste gas denitration apparatus
Inventor: ARAKAWA HIDENORI
IPC: F23C99/00
Filed: 1982-09-21
Abstract: PURPOSE:To keep the NOx value at the outlet of a denitration apparatus constant while a proper NH3 flow rate is given without delaying the adjustment of the NH3 flow rate even when load is changed, by measuring the change ratio in the flow rate of exhaust gas by temporarily increasing or decreasing the flow rate of NH3 gas corresponding to said change ratio. CONSTITUTION:The signal of an air flowmeter 2 is converted to an exhaust gas flow rate signal by a function generator 6 and said flow rate signal is multiplied by the NOx value signal of an NOx analyser 3 to obtain a total NOx content signal. On the other hand, the detection signal of an NH3 flowmeter 4 is compared to the total NOx content signal by an NH3 flow rate regulator 5 and an NH3 flow rate control signa is issued so as to eliminate deviation between both of them. In addition, the change ratio of a total NOx contect is operated by a differential operator 12 and the degree of the change is further operated from said change ratio while the ratio of an NH3 flow rate is increased corresponding to the change ratio and the degree of change when load is raised, and automatically decreased corresponding thereto when load is lowered to make the NOx content at the outlet of a denitration apparatus constant as possible.

Title: Ventilation damper
Inventor: IWASA HIDEKI
IPC: F24F13/10
Filed: 1984-08-02
Abstract: PURPOSE:To readily and automatically open and close a damper in response to the ambient temperature by supplying a weak electric current to a coiled shape memory alloy attached to the rotation shaft of the damper. CONSTITUTION:A quantity of heat equivalent to the differential temperature between the ambient temperature to be ventilated and the transformation temperature of shape memory alloy 3 is given to the shape memory alloy by causing an electric current to flow through it by adjusting the volume 5 of the power source device 4. When the room temperature is lower than the ambient temperature to be ventilated, the shape memory alloy 3 does not transform, and a damper 2 remains to be closed. When the room temperature becomes higher than the ambient temperature to ve ventilated, the ambient temperature around the shape memory alloy 3 also rises, which, together with the temperature increase due to the weak electric current, causes the shape memory alloy 3 to deform to lift the damper 2 to hold same in an open position. The volume 5 is seasonally adjusted for summer and winter to modify the temperature rise of the shape memory alloy 3. In this manner, the damper 2 can readily and automatically be opened and closed in response to the ambient temperature with a less number of functional components.

Title: Driving method for liquid crystal display device
Inventor: SEKI KOICHI
IPC: H01L29/78
Filed: 1985-07-26
Abstract: PURPOSE:To reduce DC component due to a capacity between a gate and a source drain and to improve performance and reliability by adding an offset voltage beforehand to signals applied to the data line of a liquid crystal or to the voltage applied to a counter electrode. CONSTITUTION:One of source drain of a thin film transistor (TFT) 3 is connected to a data line, and another is connected to a liquid crystal 4, and the gate electrode is connected to a control line. The offset voltage is added to the signals applied to the data line or to the voltage applied to a counter transparent electrode to cancel the DC component in order to prevent the application of the DC component to the liquid crystal 4. For instance, the offset voltage applied to the data line is supposed to be +VB. That is, if a time constant determined by a capacity Cgs between the gate and source drain, the capacity CLC of the liquid crystal, the resistance RLC of the liquid crystal and the off resistance ROFF of TFT is longer than a period, the DC component in the state of voltage VB=0 is given approximately by -Vg.Cgs/(Cgs+CLC) when a pulse height is Vg. Accordingly, it is enough to give approximately Vg.Cgs/(Cgs+CLC) as voltage VB.

Title: Coordinate detector
Inventor: TAJIRI TETSUO
IPC: G06F3/041
Filed: 1984-08-07
Abstract: PURPOSE:To eliminate the misinput and the malfunction of a coordinate by transmitting a coordinate detecting luminous flux through a transparent sheet and reflecting irregularly this luminous flux with the pressure applied in a coordinate input mode to detect a photodetecting element. CONSTITUTION:An optically transparent sheet 14 is set newly at an area including a position detecting area 1, and light sources 2a-2e and 4a-4e are set opposite to photodetecting elements 3a-3e and 5-5e respectively on the end face of the sheet 14. Then a luminous flux is transmitted through the sheet 14 and then scatterd owing to the malformation of the area where the luminous flux is transmitted and when this area is pushed. Then the pressure is applied to the sheet 14 by an indication pen 15, and this pressed area is depressed to leed a part of the transmitted luminous flux to the outside of the sheet 14. Thus the amount of the luminous flux reaching the element 3a is reduced. Thus the output level of an amplifier 12 is lowered to attain detection of the presence or absence of a coordinate input as well as the coordinate position.

Title: Abnormality detection circuit of three-phase power supply voltage
Inventor: IMAZU YOSHIKAZU
IPC: G01R19/165
Filed: 1988-07-01
Abstract: PURPOSE:To detect abnormality such as the voltage drop and phase variation of three-phase power supply voltage by comparing levels at every phases of three-phase power supply voltage to output the first - third pulses corresponding to respective phases in parallel and comparing the same with various timing pulses. CONSTITUTION:When the power supply voltage of at least one phase of three- phase power supply voltage is lower to the single reference voltage or less in a level comparing circuit 5, at least either one of the first - third pulses is not generated. Therefore, the first and second timing pulses are not generated normally or at least either one of the second and third pulses becomes absent or a pulse extinction signal is generated. Therefore, the logical values of two output signals from a latch circuit 7 are different from those t a normal time and a signal of the second logical value different from that at a normal time is taken out of a logical circuit 8 as an abnormality detection signal.
