Filed: 1989-03-17
Abstract: PURPOSE:To eliminate a fluctuation of an intermediate voltage by a temperature change and to offer a magnetic sensor provided with an excellent temperature characteristic by a method wherein a magnetoresistance element and an externally attached resistance are constituted of an identical material. CONSTITUTION:Magnetoresistance elements 11, 12 are connected in series between terminals 14, 15; an output terminal 17 is taken out from their connection point 16. An externally attached resistance 13 is inserted between terminals 18, 16 in parallel with the magnetoresistance element 11; as a result, a middle- point potential at the connection point 16 is decided by a resistance ratio of a parallel combined resistance of a resistance value R1 of the magnetoresistance element 11 and a resistance value R2 of the externally attached resistance 13 to a resistance value R3 of the magnetoresistance element 12. During this process, the externally attached resistance 13 is constituted of a material identical to a material of the magnetoresistance elements 11, 12. Accordingly, since a temperature coefficient of the magnetoresistance elements 11, 12 is identical to that of the externally attached resistance 13, it is possible to prevent the resistance ratio from being destroyed.

IPC: F02B43/00
Filed: 1994-03-14
Abstract: PURPOSE:To prevent adhesion of carbon to a venturi section and an opening of a main jet by forming a throttle valve independently from a mixer. CONSTITUTION:An air-fuel mixture forming device 6 is formed by a mixer 22 of variable venturi type and a throttle valve device 23 independent from the mixer. A throttle valve 36 can be sufficiently apart from a venturi section and arranged on the engine side. For this reason, it is possible to prevent flowing-back of pollutant substance such as oil mist which flows back in an intake air passage 25 due to blowing-back of intake air, by the throttle valve in the vicinity of an engine. Furthermore, almost all pollutant substances are pushed back by the flow of intake air which goes from the venturi section to the throttle valve 36 and has comparatively high density of air-fuel mixture. Consequently, the pollutant substances do not adhere to the venturi section and an opening of a main jet 31 easily.

Abstract: PROBLEM TO BE SOLVED: To reduce difference of brightness in a border part of divided screens in an EL(electroluminescence) display device in which drive is performed by reversing polarity for each field by applying scanning voltage to a scanning electrode by push-pull operation and matrix display is performed by screen division.

Title: Stray light preventing device in electric discharger
Inventor: NAKAMURA TOSHIHARU
IPC: G03G15/02
Filed: 1979-06-01
Abstract: PURPOSE: To prevent the incidence of stray light into the corona discharger by disposing a shield means at the end part of the shield electrode of the corona discharger along the surface of the image carrier of an electrophotographic copier.  
     CONSTITUTION: In order to prevent the light by an exposure light source 4 from reflecting on the surface of an image carrier 1 and entering a corona discharger 3, a shield means 5 is disposed to the end part of the shield electrode 3a of the corona discharger along the surface of the image carrier 1 and in proximate opposition to the image carrier 1. A light nontransmittable member 5 of concave shape or a light absorbing member 7 formed with a light absorbing layer 6 of black color is used for the shield means 5. The stray light toward the inside direction of the corona discharger 3 reflects at the image carrier surface region A where no corona discharge takes place. This light then enters the inside of the light-nontransmittable member 5 and attenuates by repeating multiple reflections in its inside or goes toward the absorbing member 7 and is absorbed by its absorption layer 6. Hence, the incident of the stray light into the corona discharger 3 may be prevented.
