Title: Leakage detector for heat insulation pipeline
Inventor: ENOKI KOUJI
IPC: G01M3/18
Filed: 1982-06-16
Abstract: PURPOSE:To detect quickly and surely the generation and position of leakage, by providing a measuring device which connects plural switch devices for detecting liquid and resistors in a ladder shape and measures the resistance value between a pair of conductors thereof in a heat insulation material. CONSTITUTION:When it is assumed that a leakage accident arises in a certain position of a heat insulation pipeline 2, a switch 12 for detecting liquid near the leaking part operates and its contacts 12a close. For example, if it is assumed that the contacts 12a of the k-th device 12 from one end side of the pipeline 2 are closed, the resistance between a pair of conductors 6a, 6b changes from infinity to R0Xk, and the electric current I=E/R0Xk flows (R0= the resistance value of a resistor 11, E= the voltage value supplied to E= measuring device 15). The device 15 calculates resistance value R0Xk from the current value I, calculates further the leaking position and displays the same. Then, the generation and position of the leakage are quickly and surely detected.

Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To individually manage data for all persons entering/leaving and to clearly manage all the entering/leaving persons by managing entrance/exist/re- entrance data of the entering persons as subjects. SOLUTION: An entering/existting management system manages that all boarding persons 32 or a part of them once exit outside an airplane (b), while the boarding person 32 finishing a ticket examination processing at a boarding gate 11 installed in an airport 31 boards the airplane 33 (a), a trouble occurs in the airplane 33 immediately prior to takeoff, inspection is completed, and the exited person enters again (c). The communication equipment of the boarding gate 11 transmits entrance/exit/re-entrance data of the entering persons who once enter as the object to a center. The center stores and manages entrance/ exit data at ticket examination. The center specifies the boarding persons 32 by individual boarding tickets, who are obliged to re-enter, based on the reading of the entrance/exit/re-entrance data recorded in the boarding tickets.

Title: Level detecting circuit
Inventor: TSUKUDA FUMIAKI
IPC: H01L27/06
Filed: 1986-05-07
Abstract: PURPOSE:To obtain a level detecting circuit that can set up surely a power fail flag at the time of a breakdown of a power supply consisting of a semiconductor IC using a complementary insulated gate field effect transistor. CONSTITUTION:Both transistors (TR) M4 and M15 are fixed at a voltage level where these TR balance with each other while a steady potential is supplied to a power supply terminal V1 (since the mutual conductance of the TR M4 is extremely reduced). While the output N5 of an inverter consisting of TRs M5 and M16 having input of a contact point N4 is changed to the power supply voltage V2 from the power supply voltage V1 when the power supply voltage drops down to a potential VG. At the same time, a contact point N6 is changed to the V1 from the V2 and a contact point N7 is changed to the V2 from the V1. Then a TR M10 is turned on. Both contact point N9 and N8 secure the relation of a flip-flop and the N8 is set at a low level when the N9 is forcibly set at a high level by the TR M10. Thus a power flag is set up.

Title: Method for controlling current-carrying to heater for oxygen sensor, and device therefor
Inventor: YAMADA TETSUMASA
IPC: G01N27/406
Filed: 1995-04-28
Abstract: PURPOSE: To provide a control device in which the time up to the activation of a sensor element by the current-carrying to a heater can be controlled substantially constant, and the excessive rise of the element temperature can be also prevented. CONSTITUTION: In an air-fuel ratio sensor having a battery element 12 having porous electrodes on both surfaces of a solid electrolytic base and a pump element 13, a micro-current icp is carried to the battery element 12 after the current-carrying to a heater 30 is started, and the activation of a sensor element is judged from the electrode-to-electrode voltage VS generated at that time. The heater voltage VH is set to 12V at the start of current-carrying, and when the time until the electrode-to- electrode voltage VS reaches a prescribed voltage VS1 is short, the applied voltage is reduced to 11V. Consequently, the time until the activation of the sensor element is judged can be made substantially constant regardless of the dispersion of the sensor.  After the activation is judged, the changing state of the element temperature is monitored from the electrode-to-electrode voltage VS, and when the element temperature is changed, the heater voltage VH is increased and decreased to stabilize the element temperature.

Filed: 1991-05-10
Abstract: PURPOSE:To suppress the error of time measurement within a determined value by calculating the frequency difference caused by the temperature variation in a crystal oscillator in terms of time difference, integrating it and correcting the time. CONSTITUTION:Function instruction input is performed with a light pen 4 on the display screen of a CRT 3. The position of the input is detected by a light pen counter 5, and is given to a CPU 1.

Abstract: PURPOSE:To obtain a pigment composition improved in pigment characteristics and excellent in stability, dispersibility and flowability by the surface treatment of a copper-containing pigment with an organosilicon compound having a group reactive with an inorganic compound. CONSTITUTION:This pigment composition is obtained by the surface treatment of a copper-containing pigment comprising, e.g. cuprous oxide with at least one organosilicon compound selected from among a chlorosilane, an alkoxysilane and a silane coupling agent, in an amount of at least 0.05wt.% based on the total weight of the composition. For the surface treatment, the copper-containing pigment is coated with the organosilicon compound, or an organic silicon copper compound produced by the reaction of the copper-containing pigment with the organosilicon compound and the hydrolyzate of the organosilicon compound are deposited on the surface of the copper-containing pigment.
