Title: Method for correcting absorbancy measuring range
Inventor: IMAI TOSHIAKI
IPC: G01N21/75
Filed: 1987-08-31
Abstract: PURPOSE:To prevent the deviation of a linear range from an absorbancy measuring range so that the absorbancy can be measured for a sufficient period of time by using a difference between the two absorbancies when a reagent is first dispensed into a reaction tube and in succession a sample is dispensed thereon as correction data. CONSTITUTION:After a 1st reagent is dispensed into the reaction tube 3 in the position A (time t1), the absorbancy Q1 of this soln. is measured. The sample is then used and is dispensed into this reaction tube 3 in the position B (t2) and thereafter, the absorbancy Q2 of the soln. mixture is measured. The absorbancy of the soln. mixture increases with time as shown in the linear region L' if the 2nd reagent is dispensed into the reaction tube 3 in the position C (t3) in succession thereof. The absorbancy Qn=Q2-Q1 of the measured sample is superimposed on the upper and lower limit values QV, QL respectively of the preset absorbancy measuring range W, by which the absorbancy measuring range W' consisting of the upper limit value Q'V and the lower limit value QL is newly set. The activity of enzyme in the sample is measured from the change in the absorbancy per unit time.

Title: Casting mold
Inventor: NAKAGOME JIYUN
IPC: B22C9/06
Filed: 1983-11-16
Abstract: PURPOSE:To discharge gas to the outside of a casting mold without clogging of a vent hole when a molten metal is poured into the mold and to prevent generation of a cavity by interposing an air permeable and heat resistant material for preventing intrusion of the molten metal in the spece between a core supporting part around the vent hole and the core supporting part of the mold. CONSTITUTION:When a core supporting part 1a mounted with a net 8 which is a material for preventing intrusion of a molten metal is fitted into the core supporting hole 2a of a casting mold 2, the net 8 is inserted and packed into the space 5 between the part 1a of the initial size or reduced size and the hole 2a. As a result, the space 5 is narrowed and the molten metal 9 poured into the mold is made hardly intrudable in the space 5. Even if the metal 9 intrudes into the space 5, just the slight amt. of the molten metal can enter the gaps among the entangled strands of the net 8 and the metal 9 is solidified by being deprived of the quantity of heat. The intrusion of the metal 9 to the part of an air vent 4 to clog a vent hole 3 is thus obviated and the gas generated from a core 1 is discharged through the air vent 4 and the vent hole 3 to the outside of the mold.

Title: Crystal pulling method
Inventor: MOHENDORA ESU BAWA
IPC: C30B30/02
Filed: 1991-08-27
Abstract: PURPOSE: To provide a method for controlling oxygen and impurity distribution by suppressing the generation of silicon monoxide with a Czochralski crystal pulling up apparatus and an apparatus therefor.  
     CONSTITUTION: Bias voltage is impressed between both ends of the silicon-quartz boundary of the Czochralski crystal pulling up apparatus and is continuously monitored and adjusted. The impressed bias voltage excites the reaction to lessen the formation of the silicon monoxide. The impressed voltage is so changed as to change the stirring effect on a silicon melt. The suppression of the silicon monoxide increases the possible range of the oxygen in the silicon crystal, and further, suppresses the generation of carbon monoxide which is a carbon source.

Title: Circuit breaker
Inventor: TANAKA TAKAYOSHI
IPC: H01H73/38
Filed: 1987-08-28
Abstract: PURPOSE:To enable confirming each turning state of a breaker at a distance even when surrounding illumination is slight by displaying the emission of an indicator lamp connected to two electrodes of a plurality of the first electrodes via a feed lead through a light guiding wire provided at the front of a casing. CONSTITUTION:When an operation lever 9 at an operation front 10 is turned to the ON position, voltage is generated between two first electrodes 2 connected to each other via a feed lead wire 6 and an indicator lamp 5 lights due to said voltage. The emission of the indicator lamp 5 passes a light guiding wire 8 at the operation front 10 of a casing 1 and luminesces at the edge of said wire 8, thereby displaying an ON state. When a circuit is opened, there is no voltage generated between the two first electrodes 2 connected to each other via the feed lead wire 6, and the indicator lamp 5 does not light. Consequently, no emission is observed at the edge of the light guiding wire 8 located at the operation front 10 of the casing 1, thereby showing the open condition of the circuit.

Title: Tracking controller for recording medium
Inventor: ITO JUNJI
IPC: G11B11/10
Filed: 1996-08-15
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal operation thereafter when an optimum gain isn't set. SOLUTION: A tracking controller 1 of a three-beam method photoelectrically converts reflection light of a pair of sub-irradiation light by photodetectors 16, 17, and subtracts them after it amplifies their outputs by amplifier circuits 21, 22 to generate a tracking error signal. The gains of the amplifier circuits 21, 22 answer to a recording medium 3 of a reproducing object to be set by PWM controlling a gain setting circuit. When the amplitude of the AC component of the signal doesn't arrive at a target level even though the gains are revised plural times when gain setting operation is performed, a processing circuit 41 sets the initial adjustment value of the gain setting operation, or the adjustment value when a difference between the amplitude and the target level becomes minimum while gain setting operating in the amplifier circuits 21, 22 as a gain value.  Thus, even when the gain optimum to the recording medium 3 of the reproducing object isn't obtained, the occurrence probability of the abnormal operation of data reproducing operation thereafter is reduced.

Abstract: PURPOSE:To make improvements in control stability by controlling a vehicle for a changeover from four-wheel steering two-wheel one when wheels have satisfied these three conditions; an antiphase steering state, sudden starting state and a sudden turning state. CONSTITUTION:A central processing unit 30 of a control means 18 calculates the time displacement of engine speed by an ignition signal when rear wheels 14, 14 and front wheels 10, 10 are of antiphase respectively and a steering angle is more than a theta degree, and that their speeds exceed car speed 0Km/h and are limited to VaKm/h by a car speed signal out of a car speed sensor 26 as the result that the ignition signal out of an igniter 22 is inputted and judged by a steering turning angle signal out of a steering sensor 24. In this case, when the time displacement of the engine speed is more than Ra r.p.m. m/s, it outputs a control signal to a motor drive circuit 32 to release 4WD of the front wheels 10, 10 and the rear wheels 14, 14, stopping the drive control of an electric motor 12, and a vehicle 2 is changed over two two-wheel steering from four-wheel one without controlling the rear wheels 14, 14 for steering.

Abstract: PURPOSE:To prevent the leakage of cold air from a third chamber into a refrigerating chamber to prevent the reduction of the surface temperature of a control panel at the side of the refrigerating chamber by a method wherein a projection, projected from the control panel and accommodating a heat insulating material, is overlapped with a position facing the rear bottom surface of a drawer type tray. CONSTITUTION:A third chamber 8 is kept at -3 deg.C and a refrigerating chamber 7 is kept at 5 deg.C whereby there is a temperature difference and there is a possibility that the surface of a control panel 27 is dewed or frozen at the side of the refrigerating chamber 7 by the heat conduction of the control panel 27 inself cooled at the side of the third chamber 8. However, a projection 31 is provided at a boundary between the third chamber 8 and the refrigerating chamber 7 whereby the distance of a surface along the boundary may be elongated, the temperature reduction of the control panel 27 at the side of the refrigerating chamber 7 may be mitigated and dewing or freezing on the surface of the refrigerating chamber 7 may be prevented. On the other hand, the rear bottom surface 26 of a tray 23 is opposed to the upper surface 32 of the projection 31 on the control panel 27 and, therefore, the leakage of cold air from the third chamber 8 into the refrigerating chamber 7 may be minimized and foods in the refrigerating chamber 7, which contain much moisture, may be prevented from freezing whereby a performance, the same as the performance of a refrigerator so far, may be secured even if the structure of the third chamber 8 is simplified.
