Title: Deep well pumping-up device
Inventor: ABE RYOICHI
IPC: G01N1/10
Filed: 1985-07-18
Abstract: PURPOSE:To pump up in constant quantity and continuously without disturbing the underground water in a deep well and to enable a sampling anytime by providing the pumping pipe to pump up a fluid, gaseous body feeding pipe and suction device. CONSTITUTION:A vacuum device 20 is actuated by inserting a pumping pipe 1 into a deep well casing 3, by opening one part of each switching valve 7, 8 and by closing the other part and by feeding a compressed air into a gaseous body feeding pipe 4 from a gaseous body feeding source 5. Accordingly the residence water inside the well is ascended in the pumping pipe 1 and stored in a vacuum tank 9 via a branch pipe 6 and switching valve 7. In this case the compressed air inside the gas body feeding pipe 4 is blown out of a blow-out port 4a, so the inside of the well is not disturbed. In case of the tank 9 being filled up the switching valve 8 is opened and switching valve 7 is closed and the underground water is led to the vacuum tank 10 of the other part. With the pumping up of the residence water inside the casing 3 by repeating the opening and closing work of each switching valve 7, 8 alternately like the above the residence water inside the well is automatically replaced with the underground penetrant, so the sampling can be performed at the stage thereof.

Filed: 1987-06-25
Abstract: PURPOSE:To increase a degree of freedom on a circuit composition of a memory device, by moving aluminum from an aluminum electrode and decreasing a resistance value of a resistor to store information. CONSTITUTION:A polycrystalline silicon resistor 5 of 160OMEGA in its layer resistance is formed on an insulating substrate where a silicon oxide film 8 is made to grow on a silicon substrate 9. Next a interlayer film 7 is piled to form contact holes 3 and 4. Aluminum electrodes 1 and 2 are formed on both ends of the resistor 5 so as to obtain an electrically writable nonvolatile memory device 21. When information is written in the memory device, a constant current power source 22 is connected with the memory device 21 so that a resistance value is decreased from 160OMEGA to 50OMEGA. The resistor 5 is heated by making the constant current flow there, and aluminum electrodes 1, 2 in contact with the resistor 5 through the contact holes 3 and 4 are made to partially invade the resistor 5. The resistance value is thus decreased to increase a degree of freedom on a circuit composition in storage device.

Title: Digital-to-analog converter
Inventor: NAKAGAWA ATSUSHI
IPC: H03M1/78
Filed: 1980-11-14
Abstract: PURPOSE:To obtain a high-precision bipolar output by inverting a binary-coding weighting current equivalent to the most significant digit bit, and applying the inverted current to a current output terminal when a polarity signal is negative. CONSTITUTION:When a polarity signal is negative, a switch SWB is changed over to the side of a current mirror circuit 401. Consequently, a current which has the same magnitude with a current flowing to a transistor TR' is applied to the inverted input terminal of an operational amplifier 103. A current output obtained by controlling switches SW1-SWn by a digital input signal is applied to the uninverted input terminal of the operational terminal, so a negative output appears at an output terminal 104. Then, a weighting current equivalent to the most significant digit bit flows through the TR'.

Title: Magnetic field vector detector
Inventor: KATOU UMAKI
IPC: G01R33/04
Filed: 1981-10-08
Abstract: PURPOSE:To obtain a detector of extremely simple constitution which has the same directivity base axis with an orthogonal reference coordinate system running on a geometric center, by composing a detection coil of a main and an auxiliary winding covering a magnetic core, and determining the rate of their numbers of turns so that detection coils have orthogonal directivity. CONSTITUTION:In the figure, (x) and (y) are orthogonal coordinates running on the geometric center of a magnetic detector, and it makes no difference whether they coincide with the geometric center of a detection coil. Then, 42 and 43 are main windings of the detection coil, and directivity base axes 44 and 45 have error angles deltax and deltay to the x and y axes. The base axis 48 of directivity of auxiliary windings 47 and 48 of the main winding 43 has an angle thetasy to the y axis. Those auxiliary windings 47 and 48 are provided differentially to a driving magnetic field, and the relation of the main winding to the winding direction depends upon the relation between deltay and thetasy; when the relation between the numbers of turns of the winding N and auxiliary windings 50 and 51 of the main winding 42 is mx=-Ndeltax/thetasx, the basic axis of directivity coincides with the x axis. Further, the output thetasy of the windings 43, 47, and 46 has directivity coincident with the y axis. Thus, the detection system having orthogonal directivity depending upon the auxiliary windings is constituted.

Abstract: PURPOSE: To operate a characteristic element at or near the zero point of power voltage by using the characteristic element which has the voltage and current characteristics to apply current in accordance with the polarity of applied AC voltage when the absolute value of the applied AC voltage is smaller than its prescribed value.  
     CONSTITUTION: Characteristic element A is connected to the TRIAC gate. Ac and DC voltages are applied between AC1 and AC2 and between P and N, respectively. When LED1 emits light, light variable resistance element PC receives light input and goes into low resistance status. If the characteristic element A operates within the range of -V o  to +V o  in this case, current is applied to the TRIAC gate electrode G1 and TRIAC is ignited, then current is applied to a load in accordance with the polarity of input AC voltage. As a result, only when the instantaneous value of the AC voltage takes any value of -V o  to +V o , i.e. it does the zero point or the point nearer, the designed purpose can be attained by turning on TRIAC.
