Title: Digit input device
Inventor: JIKUMARU TETSUYA
IPC: G06F3/02
Filed: 1994-01-17
Abstract: PURPOSE:To prevent the digit errors due to increase of the number of digits by inputting each digit of the supplied numerical data through each digit input part. CONSTITUTION:For instance, one of keys K1-K4 showing the numbers 1-4 is inverted to an H level from an L level in terms of its operating state. Thus the operating states of all keys showing the numbers smaller than that of the inverted key are inverted to H levels. When the H level is inverted to the L level, the operating states of all keys showing the numbers larger than that of the inverted key are inverted to L levels. These operating states are written into a key state holding part. Then a digit input part 6 turns on a light emitting part 2 of the key kept at an H level among those keys K1-K4 stored in the key state holding part. At the same time, the parts 2 of the keys kept in L levels are turned off. Thus it is possible to always handle the numerical data with a positional concept and to prevent the digit errors due to increase of the number of digits.

Title: Burner for waste oil
Inventor: MATSUMOTO SUGIO
IPC: F23G7/04
Filed: 1980-02-14
Abstract: PURPOSE: To cause perfect combustion in the vaporizing chamber, by making waste oil vaporized making use of ejector effect.  
     CONSTITUTION: A nozzle N strongly jets air from a compressor through an end of an air pipe 6 on to a small hole 2 of a partition disc 3, to induce the air in the closed chamber 4 out and create a vacuum state, and suck out by ejector effect waste oil to the closed chamber 4 through a waste oil pipe 7 having a hole to the closed chamber 4. Short pipes 5 which face each other from three sides on the reverse side of the partition disc 3 suck out waste oil from the closed chamber 4, regardless of the position changes of the nozzle N, and generate sprays in the airs jetted from the small central hole 2. Because the spray from the nozzle N is atomized in a vaporizing chamber V by the air rotating violently in the chamber V, an ignition can be  performed easily in the chamber V. And because the blown air are supplied in the  same rotating direction as the vaporized gas, the rotation of the flame of the vaporizing chamber is accelerated to perform perfect combustion to be jetted strongly  from a flame jet pipe 10.

Abstract: PURPOSE:To provide the oxide piezoelectric material having low dielectric constant and ready sintering with large coupling coefficient ratio by setting x=0.01-0.10, a=0.05-0.35 in (Pb1-aCaa)[(Me1/3Ta2/3)xTi1-x]O3 basic composition. CONSTITUTION:In the basic composition of (Pb1-aCaa)[(Me1/3Ta2/3)xTi1-x]O3, where Me signifies any of Mg and Zn, the value of the coupling coefficient Kp in the expanding direction becomes higher than 5% even if a<0.05 or a>0.35, and spurious is frequently generated. If a>0.35, the dielectric constant becomes higher  than 300, which is disadvantageous in the application of the high frequency. If  x<0.01, the effect of Pb(Me1/3Ta2/3)O3 for decreasing the sintering temperature of the porcelain is not presented. If x>0.10, the Kp is increased. 0.05-2.0wt% of any of MnO, NiO and Fe2O3 is added to improve the sintering and polarizing properties of the porcelain.

Abstract: PURPOSE:To secure proper idle revolutions at all times by suspending boost control by means of an idle control valve while a portion opened based on the boost control of the idle control valve is being subtracted when the temperature of cooling water is less than a specified one. CONSTITUTION:An engine revolution control device has both an air regulator 5 and an idle control valve 7 interposed to auxiliary air passages 3 and 4 bypassing a throttle valve 2 in an intake air passage 1 wherein the regulator is opened in response to an engine cooling condition and the idle control valve is controlled by signals from a control means 6 but executes idle revolution control and boost control.
