Title: Solenoid relay
Inventor: ARIKAWA YASUSHI
IPC: H01H51/06
Filed: 1988-06-24
Abstract: PURPOSE:To relieve the impact force of a fixed contact with a movable contact at the time of energization and suppress noise to be generated by collision, by constructing a card in such a form that the speed of movable contact sinks in compliance with the displacement of an armature due to energization of a solenoid. CONSTITUTION:Cards 45, 46 are constructed in the form that the speed of movable contact sinks in compliance with the displacement of an armature due to energization of a solenoid 32. When an electric magnet 22 is energized, one end 40 of the armature 23 is magnetically attracted by a core as magnetic pole 30 to make angle displacement in the A direction round a point near a bend 44. At this time, a movable contact leaf spring 26 is pushed by No.1 card 45 to a fixed contact leaf spring 28. Instead of this No.1 card 45, No.2 card 46 pushes the movable contact leaf spring 26 with further enlargement of the displacement amount of the armature 23, and the movable contact 25 contacts a fixed contact 27 to achieve electric continuity. This sinks the speed of the armature 23 when the contacts collide to relieve the impact force, which will reduce the noise.

Filed: 1977-12-28
Abstract: PURPOSE: To detect that an optical spot for scanning a pattern enters a inspecting region by providing three optical detectors corresponding to the inspecting region adjacent to one another in the scanning direction.  
     CONSTITUTION: The signals detected by detectors 21 and 22 are fed to a comparator 31, and the signals detected by detector 22 and 23 are fed to a comparator 32. The timings reaching the same value are fed to zero-cross detectors 33 and 34. Then, the timing of passage through an X direction boundary by the scanning operation in an Y direction is produced at an output terminal 35, and the timing of passage throgh the boundary in the Y direction is produced at an output terminal 36. Since those boundaries in the X and Y directions have a preset relation to the inspecting regions, the timing entering the inspecting region can be detected highly accurately.

IPC: G01N33/48
Filed: 1981-10-08
Abstract: For plotting an equilibrium curve representative of the relation between the oxygen saturation value of a hemoglobin sample, such as blood, and a changing oxygen partial pressure level in a gas, the sample is initially oxygenated by an oxygen-containing gas till it is completely saturated with oxygen, and thereafter by a controlled supply of deoxygenating gas to the volume of gas acting on the sample the oxygen partial pressure is decreased in a controlled manner. The oxygen saturation value is determined from the photometrically measured light absorption parameter of the sample in the measuring space.
