Title: Level shift circuit
Inventor: WATANABE FUMIHIRO
IPC: G05F1/10
Filed: 1989-12-19
Abstract: PURPOSE:To give no influence to the input side despite the control of a shifted variable by offsetting a level shift current so as not to affect the input. CONSTITUTION:The outer voltage V0 is defined as V0 = V1 - VBEQ1 - RIL1, and the level shifted variable RIL1 varies with change of IL1. Then the voltage V0 is varied, where V1 shows the input voltage together with VBEQ1 showing the base-emitter voltage of a transistor (1) Q1, R showing the resistance value of a resistance (2), and IL1, R showing the current of a current source (3) respectively. Under such conditions, the current flowing to the (1) Q1 is defined as an input current IB = I/1 + hFEQ1 and has no change since the current I of a current source (5) is constant. Furthermore the voltage VBEQ1 has no change either. Thus it is possible to obtain a level shift circuit which has high accuracy in a simple constitution and gives no influence to the input.

Title: Magnetic bridge type sensor
Inventor: NODA YOSHIAKI
IPC: G01N27/74
Filed: 1992-12-10
Abstract: PURPOSE:To realize a sensor having a high speed response by forming magnetic circuits in parallel between N- and S-poles and forming at least one side of the circuits to include an object to be measured in which its reluctance is varied according to magnetization. CONSTITUTION:Magnetic fluxes of first and second magnetic circuits are varied in response to the magnitude of magnetization of comparison substance with gas to be measured. If an object to be detected (oxygen) does not exist in the gas to be measured, since a gas-to-be-measured chamber M1, a comparison substance chamber R2 and a comparison substance chamber R1, the chamber M1 are similarly magnetized, magnetic potentials of detecting poles i1, i2 become the same value. If the oxygen exists in the gas to be measured, its reluctance is reduced in inverse proportion to the oxygen concentration, and hence the magnetic potential of the pole i1 (i2) is moved to N-(S-) pole side of a magnet MG. As a result, when there is a magnetic potential difference between the poles i1 and i2, a magnetic flux measuring sensor D generates a magnetic flux proportional to the difference, and hence the oxygen in the gas to be measured can be detected and quantified with the generated magnetic flux quantity.
