Title: Dc current sensor
Inventor: KAWAKAMI MAKOTO
IPC: G01R15/18
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a DC current sensor having an arrangement for sustaining high sensitivity measurement in which fluctuation of output level is eliminated after integration of a split detection core. SOLUTION: After a lead 1 to be detected and a reference lead 10 are passed through a pair of detection core members 2a, 2b, the detection core members 2a, 2b are integrated by means of screws 8. Under a state where a DC current Im flows through the lead 1 to be detected, the reference lead 10 is applied with a reference current (reference signal) superposed with rectangular currents (Iref a, Iref b) having same absolute level and inverting alternately to the plus and minus sides. A decision is then made whether the variation of a detection signal (output voltage) (VDETa, VDETb) from a detection circuit having a controllable gain is equal to the variation of the reference current.  Then they are not equal to each other, gain of the detection circuit is controlled to equalize both variations and then the output of only DC current flowing through the lead to be detected is obtained under a state where the reference current is eliminated.

IPC: A01N47/10
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To obtain a carbamate-based insecticide capable of simply and sufficiently exhibiting temporal stability effect by adding a specific stabilizer to a solid formulation containing a carbamate-based insecticide to stabilize the insecticide. SOLUTION: This method comprises adding (A) a solid organic acid as a stabilizer to a solid formulation containing a carbamate-based insecticide. The component A preferably has sublimability and, for example, m-toluic acid, fumaric acid, piperonylic acid, anisic acid, salicylic acid and benzoic acid are preferably cited as the component A. For example, a method for adding the component A to a carrier containing the carbamate-based insecticide, optionally formulating the mixture with another base, etc., and stirring may be cited as the method for adding the component A. The amount of the carbamate-based insecticide may be its effective amount, for example, 0.1-20 wt.% in the formulation. The amount of the component A is 0.1-10 wt.% in the formulation. Consequently the carbamate-based insecticide is stabilized and durability of sufficient effect can be expected.

Title: Oscillator, and synthesizer tuner circuit using and am synchronous detection circuit using the oscillator
Inventor: KOMORI KENJI
IPC: H03J7/02
Filed: 1994-02-24
Abstract: PURPOSE:To generate an optional frequency by the use of only two resonators without new provision of an adjustment process. CONSTITUTION:A multiplier 5 compares phases of outputs vo1, vo2 of a 1st oscillation loop and a 2nd oscillation loop, an LPF 6 eliminates an undesired high frequency component to obtain a phase information voltage, which is converted into a control voltage Vc via an amplifier 7. The voltage Vc is fed back to a voltage variable capacitance circuit 1 of the 1st oscillation loop and the voltage-KVc resulting from the control voltage Vc inverted and multiplied by K at a voltage control coefficient device 12 is fed back to a voltage variable capacitance circuit 11 of the 2nd oscillation loop as a frequency control voltage of each oscillation loop respectively to form a PLL. Thus, the signals in the PLL are converged such that oscillating frequencies f1, f2 in each oscillation loop are equal to each other and their phase difference is 90 deg.. In this case, the frequency at which the relation of f1=f2 is in existence is optionally set depending on the control coefficient K of the voltage control coefficient device 12.

On one hand, the signal of the thermometer 3 is inputted into the device 6 through an A/D converter 8 because the absolute value of the temperature is not made known by only the camera 2. Then, said signal is compared with the result obtained by the camera 2 and is outputted into a display device 9 after correcting a temperature drift etc. of the camera 2.
