Title: Magnetoresistance effect element
Inventor: MURATA HIDEO
IPC: H01L43/08
Filed: 1989-04-26
Abstract: PURPOSE:To reduce not only hysteresis but also the disturbance of an output signal waveform by forming dimples on a stripe to stabilize a magnetic domain structure. CONSTITUTION:A ferromagnetic membrane is formed on a glass substrate and a reluctance effect element is formed by a wet etching method. Then, dimples 5 are formed on a stripe-shaped ferromagnetic membrane at a position where a magnetic wall is generated so as to provide an interval l4 and the shape of each dimple 5 is made circular or oval. Since the position where the magnetic wall is generated is present at a place 1/20 - 1/5 a width Ws3, the distance Wd6 of the dimples 5 from the end part of the membrane in the pattern width direction thereof is set to about 1/20 - 1/5 the width Ws3 and the interval l4 is set to the width Ws3 or less and the size of each dimple 5 is set to about 10mum or less. By this method, the turbulence of a signal waveform caused by hysteresis can be reduced.

Abstract: PURPOSE:To make a level of output signal constant, by detecting a potential of an input signal for performing on-off control of a differential amplifier. CONSTITUTION:A signal from an input terminal 41 is extracted at an output terminal 46 through a transistor(TR) 47, amplified at a differential amplifier comprising TRs 42, 43 and extracted at the output terminal 46 through a TR44 and a diode 45. A signal obtained at a connecting point of emitters of the TRs 42, 43 is applied to a base of a TR48 constituting a differential circuit and a bias voltage of 2.2V is applied to the base of a TR49. When the input signal is >=2.2V+1VBE, the TR48 is turned on and the output of the differential amplifier is cut off. When the input signal is lower than 2.2V+1VBE, the TR48 is turned off, the input signal is amplified and extracted at the differential amplifier.

Filed: 1984-05-25
Abstract: PURPOSE:To measure the concentration of acid and alkali simply and in a short time by adding a fixed amount of a liquid to be inspected to a fixed amount of a reagent which presents a specified pH variation with respect to changes in the gram-molecular weight of acid or base added to gauge the pH difference therebetween. CONSTITUTION:A measurement is made employing a measuring reagent which is obtained by blending multiple kinds of compounds with the pKa difference of below 1.5, especially below 1.3 therebetween while forming a linear gradient gentle in the pH variation with respect to changes in the gram-molecular weight of acid or base added in a wide pH range. Then, a fixed amount (V1ml) of the reagent is sampled to measure pH(pH1) thereof and a fixed amount (V0ml) of a liquid to be inspected is added thereto to measure pH(pH2). By so doing, the concentration CS of liquid being inspected is determined by the formula. This enables the measurement of the concentration of acid of alkali accurately and in a short time using a simple and inexpensive apparatus.

Abstract: PURPOSE:To enhance operating performance by lowering press-in load for a bush and a ball which are pressed in so as to be coupled in a bearing section. CONSTITUTION:A bush C made of synthetic resin is made up of a cylindrical section 21 having a spherical surface seat 20 in its inner surface, flange sections 22 and 23 at its cylinder mouth ends, and of at least one split 24 provided for the cylindrical section 24, and a ball D is made up of a cylindrical body 26 having a spherical surface 25 to be mated with the spherical surface seat 20, and of splits provided for the cylindrical body 26. When the bush C is pressed in so as to be coupled in a bearing section 7, the cylindrical section 21 is contracted once, but widened again thereafter, so that the bush is thereby set to prevent fall-out. And furthermore, when the ball D is pressed in so as to be coupled in the bush C, the cylindrical body is contracted once, but widened again thereafter, so that the ball is thereby held in the bush. Therefore, since both the bush C and the ball D have the slits therein, light press-in load is sufficient enough, and they can thereby be easily pressed in so as to be coupled in the bearing section.
