Title: Heating device
Inventor: OSHIO SEIJI
IPC: G05D23/24
Filed: 1991-08-28
Abstract: PURPOSE:To prevent the unsafe operation of a heating device by monitoring the voltage difference of the AD input terminals of plural temperature detecting means for a fixed time to judge a short circuit among these detecting means when the difference of detected voltage is set within a fixed range and stopping the electrification of a heating means. CONSTITUTION:An AD input terminal short circuit detecting means 11 monitors the voltage of the AD input terminals of the temperature detecting means 5a and 5b in terms of software. Then the means 11 decides a short circuit between both means 5a and 5b if these means detect the voltage of the same level and stops the electrification of the heating means 3a and 3b. The electrification of both means 3a and 3b are also stopped by a temperature control means 6 even in such a case where the voltage of the AD input terminal of the means 5a is kept at a fixed level and does not change since it may possibly be considered that the AD input terminal of the means 5a has a short circuit with another terminal. As a result, such an unsafe case where the temperature is excessively increased can be prevented and the safety of a heating device is improved.

Abstract: PURPOSE:To facilitate the handling of the captioned device as well as to reduce its cost by constituting said device which prevents the run-off of raw gas at the time of the flame failure of a burner in a gas instrument, with only mechanical parts. CONSTITUTION:When a push button 47 is pressed down, the projection part 46 of a thermal expansion body 45 is positioned below the pin 44 of a bimetal 43 to permit a valve 40 to be opened. When a burner is fired, the heat is transmitted from a heat receiving body 41 to the thermal expansion body 45 and the bimetal 43, and the thermal expansion body 45 firstly expands to further open the valve 40. And thereafter, the bimetal 43 is bent outward to be disengaged from the thermal expansion body 45. Accordingly, the thermal expansion body 45 is pushed up. However, in this situation, the valve 40 has still opened. When the burner goes out, the thermal expansion body 45 contracts due to the lowering of temperature, allowing a rod 48 to be raised and the valve 40 to be closed.

When the CPU 11 starts the reading part 21, the reading of the original is started and the counting-down of the parameter ts is simultaneously started. Then the CPU 11 compares the parameter ts with a prescribed value tp for the time required for printing-out the picture data corresponding to a sheet of the original. When the reading of the original by the reading part 21 is advanced and ts<tp is formed, the CPU 11 starts a printer 23. Consequently recording paper is extracted from a cassette and carried up to the recording starting position of the printer 23 and picture data stored in a RAM 17 are printed out.

Abstract: PURPOSE:To restrict overshoot of an air-fuel ration minimally and reduce a deviation between the air-fuel ratio and a theoretical opening so as to improve the purification ratio of a catalyst by delaying the integration control speed within a delay time after the output signal of an air-fuel ratio detecting means is inverted. CONSTITUTION:A control circuit 20 begins processing together with starting of an engine according to the signals of each sensor 11 to 16. A revolution number counter counts the number of signals from a revolution sensor 15 and gives an interruption commands to an interruption control portion when the counted number reaches the specified value. Whether mixture of air-fuel ratio is richer than that of theoretical air-fuel ratio or not is discriminated by the signal of an Ox sensor 14. If the mixture is discriminated rich, data added per unit time in a rich delay counter is cleared and it is discriminated whether a delay time A which is the specified value has passed or not. If it is discriminated that the delay time A has not passed yet, a minimum integrated unit is subtrated from a feedback compensated amount register concerning air-fuel ratio.

Title: Driving circuit of display elements and driving method thereof
Inventor: NAKANISHI TAKAYUKI
IPC: G02F1/133
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal display of a bright line, and a point, etc., caused by disconnection of a power source. SOLUTION: A switch control circuit 213 is operated with a voltage VCH, and produces stepped up voltages V1-V4 higher than by a power source voltage VDD by distributing the charge in the electron carrier capacitor CC to booster capacitors C2 to C4. A signal drive circuit and a scanning drive circuit select a voltage from VDD and V1-V4 as necessary and apply it on liquid crystal display elements for driving them. When the power source is disconnected and the power source voltage VDD is decreased, a power source voltage detecting circuit 30 detects that and turns on a switch SW9. Moreover, the switch control circuit 213 operates on the electric charges stored in a capacitor CG to turn on all of the switches SW1-SW8.  Thus, the electric charges stored in the capacitor CC and C1-C4 are discharged and all the output voltages of the power source circuit 21 are lowered to the earth voltage VSS, and abnormal display such as bright lines, etc., is prevented.
