    摘要： An apparatus for detecting astigmatic axes and measuring refractive powers such as the lens of a human eye. A disc has a first group of slits oriented in one direction and a second group of slits oriented perpendicular thereto. Each slit has a deflecting means with a direction of deflection perpendicular to the lengthwise direction of its slits for measuring the refractive power. The apparatus also has astigmatic axis detecting target means which can be used immediately prior to the refraction so that the refraction on each astigmatic axis can be measured before conditions change in the eye.

    摘要： In an electro-optical light shutter device using a solid-solution ceramic material for alternate transmission and interception of light, a first voltage is applied to the solid-solution ceramic material in the operating (open) position of the shutter, and a second voltage of polarity opposite to that of the first voltage and having an absolute value smaller than that of the first voltage is applied to the solid-solution ceramic material in the non-operating (closed) position of the shutter. The solid-solution ceramic material has a composition in which a ferroelectric phase and a non-ferroelectric phase adjoin each other through a morphotropic phase boundary.

    摘要： Apparatus capable of tridimensionally measuring the distance between two arbitrary points on the surface of a sample is disclosed. In apparatus wherein the surface of the sample to be observed is scanned with an energized beam, wherein a secondary radiation emitted from the sample is detected and wherein a sample image is displayed by making the detected signal a video signal, two sample images obtained by changing-over the incident angle of the beam on the sample surface are displayed, whereby the stereoscopic viewing of the sample surface is enabled. In this invention, there is added means for superposing and displaying marks at two positions of both the sample images as correspond to two arbitrary points on the sample surface and for automatically calculating the tridimensional distance between the two points on the sample surface on the basis of positioning signals of the marks.

    摘要： A pump characteristics expression of a pump is developed based on a closed-state pressure detected when the pump is driven while a space between a pump passage and a first passage is closed, an open-time pressure detected immediately after the space is opened while the pump is operated, and a flow rate characteristics expression of the pump passage. A reference pressure is determined by an intersection point between the pump characteristics expression of the pump and a flow rate characteristics expression of an orifice having a predetermined passage area. A leak check portion determines whether a leak of fuel evaporation generated from a fuel tank is within an allowable range by comparing the reference pressure and a pressure detected when the pump is operated for a predetermined period while the space is opened.
