Abstract: PURPOSE:To prevent abnormal combustion on a burner when the pressure in a room where an apparatus is installed is lowered in case that the number of revolution of a fan is lowered in the state that the combustion rate of a burner is at the minimum or nearly the lowest, by providing a controlling circuit to control a fan in accordance with the combustion rate of a burner, and a lowest limit circuit to set the lowest number of revolution for the fan, and by connecting the output of a room pressure sensor which detects the pressure in a room to said lowest limit circuit. CONSTITUTION:In a lowest limit circuit 49, a room pressure sensor 43 detects the room pressure in a room where an apparatus 1 is installed. The output of a sensor 43 is amplified by operational amplifiers 44, 45, 46, 47, and then it is fed into the positive input of an operational amplifier 38 in a PID circuit 20 through a diode 48. When the difference between the temperature in tap hot water and a set temperature is very small, a proportional control valve 6 is throttled, the output of an operational amplifier 37 is made lower than that of the lowest limit circuit 49, and a fan 9 is controlled to the revolved at the lowest number of revolution based on the output of an amplifier 37, the room pressure sensor 43 detects the pressure in a room if it is lowered down to the negative pressure. The positive input voltage of an operational amplifier 38 in the PID circuit 20 is varied based on the detected negative pressure and the lowest number of revolution of a fan 9 is increased.

IPC: B41M5/333
Filed: 1983-03-14
Abstract: PURPOSE:To improve image reliability, by using a specific compound as the coupler of a heat sensitive recording material utilizing the developing reaction between a leuco dye and the developer. CONSTITUTION:A leuco dye layer, a water-soluble resin layer, an ultraviolet curable resin layer and a coupler layer are laminated onto a support in this order. In this case, as the above mentioned coupler of the coupler layer, a thiourea derivative represented by formula (wherein R1 and R2 are hydrogen, halogen, a trifluoromethyl group or an 1-4C alkyl group) is used. Because the coupler layer and the leuco dye layer are separated by the ultraviolet curable resin layer as mentioned above, the obtained heat sensitive recording material is excellent in preservability and, when irradiated with ultraviolet rays after receives printing under heating by a thermal head, the ultraviolet curable resin is cured and the leuco dye layer and the coupler layer in the background part are separated by the strong cured resin film and, therefore, color development is not generating even by re-heating. That is, by irradiating ultraviolet rays after printing under heating, the printed image can be fixed. In addition, because the thiourea derivative is used as the developer, the obtained color image is excellent in chemical resistance. In the formula, R1 and R2 represents hydrogen, trifluoromethyl group or alkyl group with C1-C4.

Title: Screen muting method for electronic still picture reproducing device
Inventor: ABE KOICHI
IPC: H04N5/765
Filed: 1986-02-27
Abstract: PURPOSE:To insure a picture against being projected while the rotational frequency of a recording medium is unstable by detecting the deviation of a pulse generated by synchronizing with the rotation of a recording medium from an independently set reference signal and outputting a mute signal in a video signal processing circuit. CONSTITUTION:A recording medium rotation synchronizing pulse generator 6 generates a pulse signal synchronizing with the rotation of the recording medium 2, and inputs it as an interruption request pulse to a microcomputer (MC) 8 through a waveform shaping circuit 7 at every rotation of the recording medium 2. After the MC 8 saves the current value of a timer in a memory, it clears the timer, and reactivates it. Thus the saved value of the timer turns out to be the hourly interval between the current and preceding interruptions. Since the hourly interval is equivalent to the rotational frequency of the recording medium 2, it is compared with a preset reference value, and checked to lie within a normal range. If not, the mute signal is outputted to a video signal processing circuit 5.
