Title: Combustion controlling device
Inventor: SASAKI HIROSHI
IPC: F23N5/20
Filed: 1982-12-29
Abstract: PURPOSE:To ensure an operating reliability and improved safety despite the failure or malfunction of plurality of relays etc., by enabling the device to operate with an ample safety margin. CONSTITUTION:While a first switch SW1 is retained as switched into a make contact side due to the failure of first relay RY1, an initial ignition can be made properly. In such a case of flame being extinguished before fully ignited, a timer 30 actuates as an off-timer and a second switch SW2 is turned to a brake contact side, bringing a main valve 2 and a pilot lamp 2 into closures. If a power fails while the second switch SW2 is retained as turned to the make contact side due to the failure of second relay RY2 from the start-up of operation, an energizing loop is formed for the first relay RY1. However, the first relay RY1 is not energized and therefore the pilot valve 1 is not opened. Moreover, if a power switch is turned ON while a third switch SW3 is retained as turned to the make contact side due to the failure of third relay RY3, a supply of actuation voltage may not take place to valves 1, 2 and ignition device 3 due to the presence of first relay RY1 and diode D4, and thereby also reliably preventing an erroneous function in this case.

Title: Limiting current-type oxygen sensor
Inventor: TSURUTA KUNIHIRO
IPC: G01N27/41
Filed: 1989-09-08
Abstract: PURPOSE:To improve processability and productivity and to stabilize characteristics for a long term by allowing a spiral spacer to tightly and rigidly secure a solid electrolytic plate with a seal plate through heating and melting of a protruding body of a mixture of glass and heat-proof very fine particles of a predetermined particle size and a film made of glass. CONSTITUTION:A spiral spacer 5 is placed between one surface of a solid electrolytic plate 1 and a seal plate 6. The solid electrolytic plate 1 with conductivity of oxygen ions has electrode films 2 formed at either face thereof. A protruding body 5a of a mixture of glass of the spacer 5 and heat-proof very fine particles of a predetermined particle size is tightly secured, via a film 5b made of glass, between the electrolytic plate 1 and seal plate 6 through heating and melting. A scattering hole 7 is formed in the spiral room and the oxygen is scattered through this room to the electrode film 2. Therefore, the scattering hole 7 is formed with good productivity simultaneously when the electrolytic plate 1, seal plate 6 and spacer 5 are bonded. Since the scattering hole 7 is formed parallel to the electrolytic plate 1, invasion of dust or foreign substance can be prevented. Moreover, the scattering hole 7 can be formed in the periphery of the electrode film 2 with a large opening area and a large length, thus improving the accuracy in size.

Title: Semiconductor storage circuit
Inventor: OKAJIMA YOSHINORI
IPC: G11C11/34
Filed: 1982-12-29
Abstract: PURPOSE:To draw a current only in transition from a selected state to an unselected state by controlling a PNP type transistor (TR) for discharging of a negative-side word line through a TR which responds to a word line indication signal. CONSTITUTION:When an address applied to a terminal drops to a low level and a word line W<+> is unselected, a TRT1 turns off together with a TRT2 for selecting the line W<+>, and the base potential of a PNP TRT3 connected to a constant voltage resistance R drops through the level shifter 2 consisting of diodes D, etc. Then, the TRT3 turns off to discharge a word line W<->. Then, the potential of the TRT3 drops speedily to complete transition to an unselected state, and then the base potential has a value determined by the resistance R, turning off the TR3. Consequently, the current of a word line is drawn by discharging only in the selected-to-unselected transition to obtain a bipolar type RAM of simple constitution which has small power consumption and eliminates the need for a large-capacity element.

Title: Multifunctional optical signal processing system
Inventor: KOBAYASHI TETSUO
IPC: G02B6/12
Filed: 1986-10-01
Abstract: PURPOSE:To obtain a multifunctional system by generating light beams of frequencies which are shifted by a constant frequency and phase-locked by plural coherent light source which are arrayed linearly at equal intervals, and obtaining deflected light by the interference among those light beams. CONSTITUTION:The plural laser light sources S1-SN are arrayed linearly at equal intervals (d) and output laser light beams emitted by adjacent laser light sources are shifted in frequency by an oscillation frequency DELTAnu successively, frequency-synchronized with one another at a constant period, and phase-locked. The light beams from the respective laser light beams intensify one another and shift in position laterally by one cycle of 1/DELTAnu to generate deflected light beam. The respective beams are therefore in continuous wave motion of single frequency and the composite light beam of the laser light beams become a fast deflected light beam when the difference DELTAnu in oscillation frequency between adjacent light sources is set large, thereby easily realizing a deflecting speed of several - several tens of GHz. Consequently, a multifunctional fast light signal processing system which has superior practicality is obtained.

Abstract: PURPOSE:To obtain a stable hot water temperature by providing a means for detecting vibration of a hot water mixing valve at the time of driving the mixing valve, and adjusting the output of an alternating signal generating means by the signal of the detecting means to suppress the vibration of a valve shaft. CONSTITUTION:The balance point of the pushing force between an energizing means 19 and a plunger 22 is changed according to the magnitude of the current sent to a coil 23, whereby the openings of hot water side and water side valve bodies 4, 6 are changed, and the hot water temperature is adjusted to a set temperature. As the plunger 22 is protruded and recessed in the coil to distort the waveform of driving signal when a valve shaft 8 is vibrated by disturbance, a difference is formed when the signals of the detecting means 24 and an alternating signal generating means 27 are inputted to a comparing means 28 to determine the phase difference. Thus, the comparing means 28 detects the phase difference and transmits it to a main control means 25, in which the generation of vibration can be detected. When the vibration is detected, the main control means 25 outputs a signal to the alternating signal generating means 27 to suppress the vibration, and the amplitude or frequency of the alternating signal is changed, whereby the balance point of the vibration is changed to suppress the vibration.
