Title: Temperature compensator for magnetostrictive sensor
Inventor: KATAOKA ICHIRO
IPC: G01L1/12
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To obtain the temperature detected value exhibiting flat temperature characteristics compensated for negative temperature characteristics by compensating the negative temperature characteristics exhibited by the stress detected value based on the stress detected value detected by stress detecting means and the temperature detected value detected by temperature detecting means. SOLUTION: When a compression force is applied to an magnetostrictive element 3, the permeability of the applying direction is increased, the symmetry of the magnetic flux distribution by an exciting coil 5a is collapsed, the voltage proportional to the force is generated in a detecting coil 5b, and a first amplifier 23 outputs a first voltage Vo exhibiting negative temperature characteristics. Exciting power 19 is supplied from an AC exciting power source 19 to the coil 5a. Even if the atmospheric temperature around a magnetostrictive sensor 1 is varied so that the resistance value of the coil 5a is varied, the current value flowing to the coil 5a does not alter, but is maintained at a predetermined value, and the amplitude of the excited voltage applied to the coil 5a is varied.  That is, a second voltage Vt exhibits the positive temperature characteristics for raising the voltage value as the temperature rises. This is canceled by the first voltage Vo of the negative temperature characteristics to obtain the compensated output voltage Vot.

Abstract: PROBLEM TO BE SOLVED: To obtain glass having high transmissivity in the vacuum ultraviolet region and high resistance to ultraviolet rays by subjecting an organic silicon compound to hydrolysis or oxidation reaction in an oxidizing flame to obtain glass particles, depositing the glass particles on a target and heat treating the resultant deposit in an atmosphere containing hydrogen. SOLUTION: A compound having a boiling point of <=170 deg.C, e.g. hexamethyldisiloxane is used as an organic silicon compound. The oxidation reaction of the raw material is accelerated and completed by setting the ratio of oxygen to hydrogen to be not less than 0.53 at the time of the synthesis. Treatment in a hydrogen atmosphere is carried out at a temp. of <=500 deg.C, at which alkaline impurities hardly diffuse. In heat treatment, the oxygen partial pressure is set to be not less than 0.1 atom at which alkali impurities hardly diffuse, and the temp. is set to the temp. range of >=900 deg.C, at which temp. range stress, or the like can be suppressed. The suitable flow rate of hydrogen gas is not more than 60 m/sec.  A burner has a raw material ejecting pipe which is provided at the center part and a hydrogen ejecting pipe and oxygen ejecting pipe which are provided at the peripheral part, thereby the area where oxygen is excessive and the area where hydrogen is excessive are provided.

Title: Fault detecting device of insulating gloves for dielectric strength
Inventor: MIURA YOSHIZOU
IPC: G01R31/12
Filed: 1981-06-11
Abstract: PURPOSE:To detect a flaw or a fine hole of gloves easily at any time, by obtaining DC voltage from a commercial electric power supply by a switching control system, applying it to insulating gloves being an object to be tested, and deciding whether a feeble current flowing in that case is large or small. CONSTITUTION:Insulating gloves 9 to be tested are put into a water tank, are pinch-held by a clip, etc., and after that, an electrode 10 is put into the inside of the gloves, and an electrode 12 is put into the water tank. As soon as an electric power supply is turned on, for instance, DC voltage of 300V is generated in a testing circuit 6, and is applied between the electrodes 10, 12. On the other hand, in a detecting circuit 8, for instance, DC voltage of 10V is induced, and it is applied to a comparator CO and the second light emission diode LED2. In case when the insulating gloves 9 are in a satisfactory state and a leakage current is within an allowable range, the LED2 is lighted even when voltage across a variable resistance R22 is a reference value or below, but if a current exceeding a prescribed value flows, the voltage across the R22 rises, voltage exceeding a threshold level flows to an output of the CO, and as a result, a light emission diode Rh generats light, therefore, insulation failure can be tested easily.

Title: Heat load measuring method of blast furnace body
Inventor: NISHIYAMA TETSUJI
IPC: G01K17/20
Filed: 1978-07-21
Abstract: PURPOSE: To improve the accuracy of the measurement of the heat load of a blast furnace body, by measuring thermal flow bundles at the center of the bottoms of concave grooves set so that the isothermal curves in the concave grooves of a cooling device of the blast furnace body approximately be parallel in the height direction of the furnace body.  
     CONSTITUTION: A plurality of concave grooves 10 for facilitating furnace wall inner surface firebrick support are arranged to a surface facing to the furnace inside of a stave cooler 3 at intervals in the furnace height direction, casting bricks 12 are casted into the concave grooves 10 and a detecting portion of a thermal flow meter 14 is mounted to a point A of the center of the bottoms of the concave grooves 10. When the depth l of the concave groove 10 is long and the width d is small, the isothermal curve large meanders in the concave groove 10; when the width d is lengthened and the depth l is shortened, the meandering of the isothermal curve is improved. The larger the heat transfer rate λ of the casting bricks 12 is the less the less the effect of the depth l and width d of the concave grooves 10 becomes. Thus, the accuracy of the measurement of heat load can be bettered by selecting the shapes of the concave grooves 10, which do not produce the meandering of the isothermal curves, and the heat transfer rate λ of the casting bricks 12.

Title: Phase shifter
Inventor: MIYASHITA KAZUHITO
IPC: H01P1/18
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive phase shifter by constituting a triplate line inner conductor by means of a triplate line which is inserted into the three spaces of the inner conductors of two coaxial lines and is also moved in the center axial direction of the inner conductors of the coaxial lines. SOLUTION: Since the end surface side of the fourth space 17 is short- circuited, an operation is electrically executed as OPEN in the second space 15 which is apart from there by one-fourth wave length. The operation is executed as SHORT in the coaxial line end surface of the first space 14 being apart from there by another one-fourth wave length. Therefore, the triplate line inner conductor 12 is operated so as to be normally electrically connected even when it is moved in a mobile direction at the electric connecting point 19 of the coaxial line inner conductors and the triplate line inner conductor. A line mobile part is adopted as the triplate line so that an outer conductor is not required to be moved. Thus, a choke is not required to be used for the outer conductor so that the phase shifter is inexpensively produced.
