A visual function test apparatus for testing a visual function by presenting an optotype to an examinee's eye is disclosed. This apparatus includes a first half mirror disposed on a projection optical axis of light of the optotype; an illumination light source having a projection optical axis which is made substantially coaxial with the projection optical axis of the optotype light by the first half mirror; a concave mirror which reflects an illumination light from the illumination light source and the optotype light; a second half mirror disposed between the first half mirror and the concave mirror, the second half mirror reflecting the optotype light and the illumination light both reflected by the concave mirror toward the examinee's eye; and a control section which changes a ratio between a light quantity of the optotype light and a light quantity of the illumination light in accordance with a predetermined contrast ratio.

A visual acuity testing apparatus comprises a casing having at least one test window which an examinee looks into, and at least one optotype presented inside the casing which is disposed in such a position that its optotype plane is tilted relative to a datum plane orthogonal to an axial line connecting the test window to an optotype presentation position in order to prevent that light entered through the test window and reflected from the optotype plane, passes through he test window again.

A scroll compression device that prevents scattering of lubrication oil to a discharge pipe side is provided. A cup 48 which is opened at the lower portion thereof and prevents scattering of lubrication oil is disposed on the lower surface of the main frame 21, and an annular insulator 19 having a double wall structure which surrounds windings is disposed on the upper surface of a stator 37. The peripheral wall of the cup 48 is hung between the double walls 19A, 19B of the insulator.
摘要:
A scroll compressor including a casing, a scroll compression mechanism that compresses refrigerant, a driving motor that has a driving shaft, an insulator and a stator, and is connected to the scroll compression mechanism through the driving shaft to drive the scroll compression mechanism, a main frame that supports the scroll compression mechanism in the casing, a bearing plate that has a boss portion in which the driving shaft is inserted, and supports the driving shaft of the driving motor in the casing, and a cover that covers the surrounding of the driving shaft between the driving motor and the bearing plate and is formed of an insulating material and provided to the insulator of the driving motor.
