Title: Electric expansion valve control method for air conditioner
Inventor: NAGAO TOMOHIRO
IPC: F24F11/02
Filed: 1990-09-17
Abstract: PURPOSE:To eliminate the condition in which all indoor electric expansion valves are fully closed, thereby stable operation control being ensured, by checking that at least one electric expansion valve is not fully closed before the electric expansion valve of each indoor unit is fully closed. CONSTITUTION:Assume that all indoor units 2a, 2b are in cooling operation. When the operation of one indoor unit 2b stops, a fully closing control means 16b judges from the communication data of indoor transmission means 15a, 15b whether all electric expansion valves of another indoor unit 2a are fully closed or not. When even one electric expansion valve 9a is not fully closed in another indoor unit 2a as a result of this judgment, the fully closing control means 16b tells to a valve opening control means 13b that the electric expansion valve 9b is to be closed. The valve opening control means 13b fully closes the electric expansion valve 9b. Next, the indoor unit 2a in operation is stopped by a line 21. Since all electric expansion valves 9b of another indoor unit 2b are fully closed, an electric expansion valve 9a is not fully closed, and a compressor 3 is stopped.

Title: Both-surface image forming device
Inventor: AOKI TOMOHIRO
IPC: G03G15/20
Filed: 1983-12-29
Abstract: PURPOSE:To suppress the generation of curling of a sheet which impedes the copying of the 2nd surface and save energy by equalizing the degree of fixation during the 1st surface fixation and the 2nd surface fixation of both-surface image formation to each other, and making it lower than that in one-surface image formation. CONSTITUTION:A heat source 53 has a main heating body 53a and an auxiliary heating body 53b, which are both powered on during the fixation of the one-surface copying operation, but only the main heating body 53a is powered on in both the 1st surface copying and the 2nd copying of both-surface copying operation. The detection level of a thermistor is varied to control the set surface temperature of a fixing roller to 190 deg.C in the one-surface copying or to 170 deg.C in the both-surface copying. Consequently, the heating value applied to a sheet is reduced in the both-surface copying operation and the degree of fixation is decreased.

Title: Deciding method for silic-blowing of drum water in drum type boiler plant
Inventor: KIYAMA MASASHI
IPC: F22B37/42
Filed: 1993-10-04
Abstract: PURPOSE:To enable a non-required blowing discharge of drum water to be prevented by a method wherein an allowable tolerance value of concentration of silica in drum water is accommodated for a variation in pressure of boiler. CONSTITUTION:A measured value signal of a boiler pressure measured by a pressure gauge 22 is sent to a computer 30, wherein a concentration of silica obtained by a function F(X) selected in response to a boiler pressure is compared with a silica concentration of actual drum water measured by a silica meter 21. If the silica concentration in the actual drum water measured is high, it is discriminated that a blowing discharge of the drum water is necessary. Then, the drum water is blow discharged in response to the decision, thereafter new boiler water is supplied. In this way, the allowable tolerance of silica concentration in the drum water is accommodated for a fluctuation in the boiler pressure where a pressure varying operation is carried out. With such an arrangement as above, it is possible to prevent non-required blow discharging of the drum water.

IPC: F23D14/08
Filed: 1988-09-30
Abstract: PURPOSE:To form short flames which are of an uniform length and stable and, furthermore, prevent the lifting of flames at the time when the oxygen supply is low by arranging in many flame holes which are provided in parallel on the upper face in the longitudinal direction small flame holes which have their width that is about half of the width of said flame holes in the direction o short side. CONSTITUTION:A plurality of rows of flame holes 8 are formed on the upper face in the longitudinal direction of a burner main body 1 with a burner main body 3 for forming inside flame holes and burner main body 2 for forming outside flame holes and a flame holes partitioning plate 4 which is held between those burner main bodies and partitions the flame holes 8. This group of the flame holes 8 have flame holes 8a arranged at every other position among them. Those flame holes 8a have their width in the direction o short side that is about half of the width of the flame holes 8. Primary air for combustion that is sucked from a suction section 5 and gas are mixed into a mixture gas in a mixing pipe section 6 and the mixture gas which is unified in pressure in a pressure unifying section 7 is jetted out from respective flame holes 8 and 8a to burn. And, at the section of the small flame holes 8a the supply of secondary air for combustion becomes plenty, and flames 12a are shorter than flames 12. Further, since even in the combustion with a small supply of oxygen the long flames 12 and short flames 12a are arranged adjacent to one another, the long flames 12 suppress the lifting of the short flames 12a.

Title: Solar light power generation controller
Inventor: ABE JUN
IPC: H01L31/04
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To prevent an operation point from being misjudged by finding a control indication value at present sampling time from the output electric power of a solar battery and the control indication value of a control signal in each sampling cycle. SOLUTION: An arithmetic part of a control part 6 reads in the output current signal and output voltage signal of the solar battery in each sampling cycle and operates the output electric power PN. Then when the mode is not an excessive solar radiation quantity mode, the solar battery output electric power PN at the present sampling time is compared with the solar battery output electric power PB at last sampling time. When PN > PB, the same control indication value as that at the last sampling time is held as it is. When PN < PB, on the other hand, a control indication value which makes an input current increase or decrease opposite from that at the last sampling time is set.  When PN equals PB continuously at a prescribed sampling frequency, the control indication value is set to the inverted value of that at the last sampling time and the excessive solar radiation mode is entered at next-time sampling time; and the control indication value is not re-set until PN becomes less than PB.

Title: Sectional once-through boiler
Inventor: FUJIOKA ISAMU
IPC: F22B13/00
Filed: 1988-09-30
Abstract: PURPOSE:To obtain a sectional boiler by fixing one first section and a number of second sections arranged in parallel by bolting them, by enclosing them with a heat- insulating material from the outer side, by connecting the upper steam outlets of the individual sections by a manifold, by connecting the lower ports for fallen water by a manifold, and by connecting the manifolds to a steam separator at a side by a main pipe and a downcomer. CONSTITUTION:The boiler water under a normal water level is turned by heating to steam, which is collected in an upper manifold 18 and led through a main pipe 19 into a steam separator 20 where steam is sent out through an upper main stop valve 35. The water separated from steam falls through a downcomer 23 and enters the lower laterally laid part 4 of the pipe of each section. Water is automatically supplied to them by a pump which operates in a linkage with the fall of the water level from the normal level. Built entirely of steel pipes by welding, the boiler is resistant to high pressure and the vaporization capacity can be freely altered by increasing or decreasing the sections in use in number. The heat-transferring efficiency is excellent, since the combustion chamber 30 is formed entirely by water-cooled furnace walls and the flames flow on a three-paths system. The tilted pipes in the middle forms such an inclination that air bubbles flow satisfactorily without the possibility of causing a water hammer, hence safety of the operation is insured.

Filed: 1987-09-30
Abstract: PURPOSE:To enable the photodetection of the fluorescence in a 90 deg. direction where the Rayleigh scattering of excitation light is smallest by providing a migration gel and excitation light beam as well as a detector part, etc. CONSTITUTION:The excitation light beam 32 scanned in the direction orthogonal with the migration direction by a galvanomirror 34 escapes in the normal direction of the migration gel 2 at all the boundary faces with the gel 2 and, therefore, multireflections do not take place. Fluorescence is emitted from the nucleic acid fragments migrating in the gel 2 and propagates in the gel 2. The fluorescent light appearing at the end face of the gel 2 is detected 56 through light guides 50, 52 and an optical fiber bundle 54 and is converted to an electric signal. The signal indicating the projection position of the beam 32 onto the gel 2 from the rotating angle of the mirror 34 is taken into a signal processing part 58 which takes the fluorescent light in said position therein as the detection signal of a detector part 56. The development pattern of the DNA fragment specimen developed by electrophoresis in the gel 2 is obtd. as the fluorescent detection signal of the detector part 56 by scanning the entire surface of the gel 2 by the mirror 34 in such a manner. The direction where the fluorescent light is photodetected is 90 deg. with the beam 32 and the propagation of the Rayleigh scattering light is minimized.
