Patent JP-H1055762-A (JP)
Title: Magnetron
Inventor: MIKI KAZUKI
IPC: H01J23/00
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To perform stable oscillation by arranging a first getter for a cathode, arranging a second getter at a position becoming a temperature lower than the cathode during magnetron operation in an anode cylinder, and absorbing gas in the magnetron. SOLUTION: A first getter 19 is arranged for a cathode 4, and a second getter 20 is arranged at a position becoming at a temperature lower than a cathode 4 during magnetron operation in an anode cylinder 1. When a magnetron is just manufactured, gas is produced in a vacuum part, and much gas remains. At this time, the remaining gas can be absorbed completely by the getter 19. Next, when the magnetron is used during long period, gas in which the gatter 19 deteriorates is not absorbed so much. In addition, discharge gas is lessened. At this time, the getter 20 can still absorb gas, gas absorption speed is low, but an amount of the gas in the magnetron is very rare, therefore, the gas is absorbed in the getter 20. Thus, the vacuum state of an oscillation part can be maintained for a long time, and stable oscillation can be performed.

Filed: 1986-09-04
Abstract: PURPOSE:To prevent driving by a person having no license by providing a photoelectric converting means for optically reading the license number, etc. of a license, comparing recognized letters which are recognized by processing the resultant signal with a stored information, and closing a starter circuit when both agreed. CONSTITUTION:When a license is inserted into a photoelectric converting means 1, the photoelectric converting means 1 reads it and sends a signal to a preparation means 7. The preparation means 7 extracts the characteristics of letters from a letter image which is sent as a signal and, then, a distinction means 8 estimates the resemblance to a standard pattern and distinguishes the letters. And, the letters are compared with a license number stored in a memory 13 by a processing means 9 and, when both agreed, an agreement signal is outputted to a starter control circuit 11 to close a starter circuit 12. Accordingly, only a person having a license which is previously registered can start an engine, preventing driving by a person having no license.

Title: Toner base grain, toner and developer
Inventor: KANEKO MASAAKI
IPC: G03G9/09
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To provide electrostatic image developing toner base grain that can obtain sufficient color reproducibility and coloring property with clearness by containing a specific treated pigment. SOLUTION: A small quantity of water soluble solvent serving as a wetting agent is added in a mixture of an organic pigment, rosin and water soluble inorganic salt. After kneading this mixture strongly by a kneader or the like, the mixture is put into water to dissolve the water soluble inorganic salt and water soluble solvent so as to be formed in a slurry state. Filtration and water washing of this slurry are repeated to eliminate the inorganic salt and solvent. The surface of the organic pigment with rosin refined is therefore covered so as to prevent cohesion caused by drying. Common salt, potassium chloride or the like is used as the water soluble inorganic salt. A solvent with a high boiling point is desirably used as the water soluble solvent from the viewpoint of safety. Gum rosin, polymerized rosin or the like is used as the rosin.  It is desirable that the treated pigment has an average grain diameter of 1.0 μm or less, desirably 0.2 μm or less, in measurement by laser scattering.

Title: Control circuit for air conditioner
Inventor: NODA YOSHIYUKI
IPC: F25B1/00
Filed: 1993-08-24
Abstract: PURPOSE:To prevent intermittent oscillation of a switching transformer due to reduction of load by using an expansion valve, which is connected to the switching transformer, as a pseudo load when the expansion valve is subjected to off-control. CONSTITUTION:Intermittent oscillation of a switching transformer does not occur in a mode of an expansion valve 4 acting, so that normal control of the expansion valve is effected to cause on-off control of respective inner coils A, B, C and D of the expansion valve 4. When it becomes unnecessary to actuate the expansion valve 4, a pseudo output routine takes effect. In the pseudo output routine, a loading condition of the switching transformer can be set in almost the same manner as at the time of action of the expansion valve 4 by fixing a mode of a step, in which two inner coils close to a step at the time of action of the expansion valve 4 are simultaneously energized, and feeding an electric current to the two inner coils. Accordingly, it is possible to positively prevent intermittent oscillation of the switching transformer due to reduction of load.

Abstract: PURPOSE:To prevent the breakage of a graphite crucible from occurring by dividing the graphite crucible for holding a quartz crucible on its inside, in the circumferential direction into plural pieces, providing a space between every adjacent two of the divided pieces and fitting a ceramic spacer into each of the resultant spaces. CONSTITUTION:In this device, a graphite crucible 3 is divided in the circumferential direction into about 2 to 10 equiangular pieces and a space between every adjacent two of the divided pieces such as pieces 3a, 3a, 3a is provided and a spacer 6 made of a ceramic material having heat resistance and a low expansion coefficient, such as Al2O3 is fitted into each of the resultant spaces. Then, lumpy polycrystalline Si is charged into a quartz crucible which is set in the graphite crucible 3 by holding the quartz crucible with a graphite holder and, thereafter, an induction current is generated in the graphite crucible 3 through actuating a heating means to heat the crucible 3, and thereby, to melt the polycrystalline Si in the quartz crucible. At the time of heating or cooling the graphite crucible 3, its greater expansion or contraction occurs than that of the quartz crucible, however, because of its divided structure, the graphite crucible 3 causes no breakage due to the internal stress.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: KAWANABE TOMOHIKO
IPC: F02D41/14
Filed: 1985-09-21
Abstract: PURPOSE:To suppress deterioration of an oxygen pump element of an oxygen concentration detecting means and prevent a reduction in performance, by stopping supply of current to the oxygen pump element when an output valve opening time computed by a duty control means exceeds an upper limit valve opening time. CONSTITUTION:An oxygen concentration sensor 14 comprises an oxygen pump element 21 and a buttery element 22. Each of the elements 21 and 22 is mainly formed of an oxygen ion conductive solid electrolyte material. In controlling an air-fuel ratio by an air-fuel ratio control circuit 20 with use of the sensor 14, a reference duty retrieved from a map of a suction absolute pressure and an engine rotational speed is corrected according to an operational condition to thereby obtain an output valve opening time of an injection valve. When the output valve opening time exceeds an upper limit valve opening time, there is a possibility that blackening will occur where the oxygen in the solid electrolyte material of the sensor 14 is lost. To cope with this, a command data of Ip to be supplied to a programmable voltage generating circuit 32 is made null to cut off the supply of current to the pump element.
