IPC: G01D5/245
Filed: 1989-07-17
Abstract: PURPOSE:To reduce detecting errors by so providing a magnetoresistive element as to satisfy a specific condition, and constituting a magnetic sensor by two pairs of said magnetoresistive elements. CONSTITUTION:Magnetoresistive elements (MR elements) R51-R54 as a unit to form a magnetic sensor 3 are arranged in this order. The elements R51, R52 and R53, R54 are connected in series, respectively, thereby constituting a bridge. Contacting points (a),(b) are connected through resistances to input terminals of an operational amplifier Q. The operational amplifier Q generates an output e0. This position detecting apparatus is constructed in the above manner. Each element of the MR element R51-R54 is arranged with lambda/9 pitch, lambdabeing the pitch of the magnetic recording, and formed to turn back one and a half. Therefore, the output voltage of the MR element is the sum of the voltages of the three elements and the sum of the voltages of the third harmonic waves becomes zero, resulting in fundamental waves alone. Moreover, when the elements R51-R54 are connected to form a bridge, the output voltage of the operational amplifier Q becomes the sum of the fundamental waves, so that the output voltage of the fundamental waves is obtained.

Title: Combustion melting furnace and waste treatment equipment
Inventor: TEZUKA NORIO
IPC: F23J1/00
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To improve treating efficiency of slag by preventing the slag discharged from a combustion melting furnace from becoming acicular difficult to be handled or reused. SOLUTION: A protrusion in which molten slag 32 flows from a ceiling in the combustion melting furnace is provided at an upstream side of a slag discharge port 33 so that the slag 32 does not flow directly into an opening of a slag discharge port 33 and an opening wall. The ceiling may be inclined from its center in a longitudinal direction or a curved surface ceiling. Or, it may be inclined laterally to allow the slag to move to a sidewall. According to this, the slag 32 flowing from the ceiling does not flow into the port 33 as a fine yarn-like state and is not hence solidified. Therefore, since discharge of the acicular slag difficult to be handled or reused is prevented in the combustion melting furnace and the waste treating equipment, treatment of the slag can be efficiency executed.

Abstract: PURPOSE: To obtain clear agglutination with a simple constitution so as to easily discriminate the blood type of a sample by fixing a shaking means composed of an ultrasonic wave source to a measuring cell which receives the sample and a reaction serum. CONSTITUTION: A measuring cell 10 made of transparent glass has an internal cavity limited by parallel planes 12 and 14 and a blood sample and a reaction serum are supplied to the cavity through two inlet end section fittings 16 and 18. In addition, an ultrasonic wave source 24 connected to a power source 26 is fixed to the upper surface of the cell 10. When the sample and serum are supplied to the cavity through the fittings 16 and 18, the source 24 is vibrated and agglutination takes place between the sample and serum when the sample is positive. The result of the reaction is discriminated by converging a light beam 30 passed through the cell 10 on a photosensitive surface 34 through a lens 32. Therefore, the agglutination between the sample and serum can be caused surely and the blood type of the sample can be discriminated easily.

Filed: 1982-10-20
Abstract: PURPOSE:To reduce both oil leakage and the required amount of supplementary oil and to improve responsiveness by providing an eccentric cylinder shaft with a locker arm in such a manner that the arm can be rocked and by rotating the eccentric cylinder shaft through a long operating arm, thereby lowering the oil pressure in a gap eliminating unit. CONSTITUTION:An eccentric cylinder shaft 4 is fitted to a locker shaft 3 in a freely rotatable manner, and locker arms 5i and 5e are installed on the eccentric cylinder shaft 4 in a rocking manner. The eccentric cylinder shaft 4 is provided with an operating arm 6 whose effective length from the center of the locker shaft 3 is greater than the eccentricity of the eccentric cylinder shaft 4, and the arm 6 is connected to a hydraulic gap eliminating unit. The burden of a load to the gap eliminating unit is alleviated according to the ratio between the eccentricity of the eccentric cylinder shaft 4 and the effective length of the operating arm 6. With this contrivance, the value of the maximum oil pressure in an oil pressure chamber can be lowered, thereby reducing the amount of oil leakage and therefore of supplementary oil. Thus, the responsiveness of the unit to the valve head gap is enhnaced so that the valve head gap can surely be eliminated even in high speed operation.
