Abstract: PURPOSE:To cancel noise components and to maintain the excellent S/N of a playback RF signal by altering the way of applying a bias to a couple of photodiodes for obtaining the playback RF signal so that detection currents of the couple of photodetectors are out of phase with each other, and obtaining the difference between their detection outputs as the playback RF signal. CONSTITUTION:The cathodes of the photodiodes D1 and D2 are connected in common and supplied to a positive bias voltage, and detection signals i1 and i2 are led out of the anodes. The anodes of photodiodes D3 and D4 are connected in common and supplied with a negative bias voltage, and signals i3 and i4 which are out of phase with said detection signals i1 and i2 are led out of the cathodes respectively. A subtracting amplifier 18 detects the difference between outputs of current voltage converters 3 and 5, a subtracting amplifier 20 detects the difference between current voltage converters 3 and 6, and a subtracting amplifier 21 detects the difference between the current voltage converters 4 and 5. The outputs of the subtracting amplifiers 18 and 19 are added together by a summing amplifier 11 to obtain the playback RF signal 14.

Title: Combustion device
Inventor: KOMORI MINORU

Filed: 1985-06-19
Abstract: PURPOSE:To provide a complete combustion of fuel and restrict a generation of nitrogen oxide by a method wherein combustion air is supplied from an intermediate point of heat-resistant porous object arranged downstream of a burner. CONSTITUTION:A heat-resistant porous object 5 which is supported by a partition wall 2 of a combustion chamber is arranged just above a flame hole surface 4 of a burner 3. Secondary air holes 6 are made in the partition wall 2 of the combustion chamber positioned substantially at a central part in a direction of height of the porous object 5, and the secondary air holes 6 are communicated with a secondary air hole 9 made at a lower part of the partition wall cover 7 through the secondary air passage 8. Since this combustion device has a double-stage combustion system, a volume of primary air contained in the mixture flowing out of the flame hole 4 of the burner 3 is restricted to a value lower than a theoretical air volume and the amount of air required for the remaining combustion is supplied through the secondary air holes 6. Therefore, since the combustion temperature is kept low through an entire combustion area, it is possible to restrict the production of the nitrogen oxide.

Abstract: PURPOSE:To improve a display grade even with a large image plane by superposing two layers of ferroelectric liquid crystal cells with two sheets of polarizing plates and adjusting the retardation value of the light transmitted through the liquid crystal cells at 0.13-0.26mum thereby decreasing said value. CONSTITUTION:Transparent electrodes 23, 33 and oriented films 24, 34 are formed on glass substrates 22, 32 on a segment side and electrodes 26, 36 are respectively formed to the common side substrates 25, 35. Ferroelectric liquid crystals 28, 38 are sealed therein to form the liquid crystal cells 21, 31. The cells are superposed on the segment side and are disposed between polarizing plates 11 and 21. The direction C of the polarization axis of the polarizing plate 11 is made parallel with the optical axis direction of the liquid crystal cells and the direction D of the plate 21 is made orthogonal therewith. The optical axis directions A, B of the liquid crystal molecules incline by theta in opposite directions and the retardation value of the light past two layers of the liquid crystal cells attains 0.13-0.26mu when a positive electric field is impressed to the segment side. The display grade having no interference colors is thus realized even with the large image plane at the small retardation value even if the cell gap is increased.

Abstract: PURPOSE:To improve the reliability of the flame detector having a flame rod by providing a safety device which prevents a breakdown of parts and a misoperation of firing detection in the case that the flame rod is shortcircuited to an opposing electrode for some reason. CONSTITUTION:In the flame detector, when the flame rod 1 detects out a burning flame and induces an ion current, a parallel circuit comprising a resistor 2 and a capacitor 3 outputs a flame detection voltage, which is compared with a reference voltage by a comparator 9 to determine whether the burning flame is in blue firing condition. In this instance, a Zener diode 12 is connected to a connection point of resistors 4 and 4''. This diode 12, a resistor 8 which works as a current controller and the capacitor 3 which consitutes a part of a rectifying circuit form a safety circuit for preventing a misoperation of firing detection. Thereby, if the flame rod 1 is shortcircuited for some reason, the resistor 8 and the Zener diode 12 form a path for flowing an alternating currnet signal produced by a transformer so that the relating parts are protected from breakdowns.
