  • Publication number: 20160047710
    Abstract: A reference surface is moved, relative to an optical system, to a plurality of placement positions, and a wavefront of reflected light from the reference surface is measured at the respective placement positions by a detection unit. Based on information on the wavefront measured at the respective placement positions and information on the optical system, a plurality of pieces of shape data of the reference surface are calculated. Thereafter, a wavefront of reflected light from a measurement target surface is measured by the detection unit, and temporary shape data of the measurement target surface is calculated. Error data is calculated based on a relationship between the plurality of placement positions to which the reference surface is moved and the plurality of pieces of shape data at the respective positions, and the error data is removed from the temporary shape data thereby determining shape data of the measurement target surface.

  • Publication number: 20160027735
    Abstract: In an LCD driver, in a high voltage resistant MISFET, end portions of a gate electrode run onto electric field relaxing insulation regions. Wires to become source wires or drain wires are formed on an interlayer insulation film of the first layer over the high voltage resistant MISFET. At this moment, when a distance from an interface between a semiconductor substrate and a gate insulation film to an upper portion of the gate electrode is defined as “a”, and a distance from the upper portion of the gate electrode to an upper portion of the interlayer insulation film on which the wires are formed is defined as “b”, a relation of a>b is established. In such a high voltage resistant MISFET structured in this manner, the wires are arranged so as not to be overlapped planarly with the gate electrode of the high voltage resistant MISFET.

  • Publication number: 20150362326
    Abstract: A vehicle position display controller performs a branch determination processing of determining whether a vehicle has entered a branch road. In addition, in a case where a connecting road through which a currently traveled road is connected to a road extending in parallel with the currently traveled road lies ahead of a position of the vehicle, the vehicle position display controller performs a road shape conversion processing of subjecting the road extending in parallel to the branch determination processing on the assumption that the road extending in parallel is the branch road by making a correction of an angle between the currently traveled road and the connecting road. However, in a case where the vehicle travels at a speed equal to or greater than a predetermined speed, the vehicle position display controller does not perform the road shape conversion processing.

  • Patent number: 9091534
    Abstract: To eliminate influence of undesirable light component from an object when measuring optical characteristics such as shape and wavefront aberration of the object, light from light source (101) is separated by polarization beam splitter (103) into measuring light (L1) that irradiates and travels via the object (108) and is condensed on image plane (P) through microlenses (114a) of microlens array (114), and reference light (L2) that does not irradiate the object and is guided to the image plane by reference light optical system (109).

  • Publication number: 20140233038
    Abstract: The present invention is directed to more accurately acquiring shape data than conventional techniques. After an imaging unit images an interference fringe, a calculation unit acquires the captured image from the imaging unit. The calculation unit extracts a ring zone region where the interference fringe is sparse in the captured image from each captured image, and calculates a phase distribution of the interference fringe in each ring zone region. The calculation unit acquires a deviation component having an orientation and an amount both unchangeable along a circumferential direction of a circle centered at the optical axis of the subject light by analyzing the interference fringe contained in each acquired captured image. Further, the calculation unit calculates positions of characteristic points of a calibrator, and calculates a distortion component. Then, the calculation unit calculates the shape data corrected based on the deviation component and the distortion component.

    Abstract: A cutting liquid supply device in a machine tool is configured to remove gas mixed in a cutting liquid supply line to improve the response of discharging a mist of cutting liquid. Cutting liquid is supplied from a pump (42) through a rotary joint (28) to a mist generation device (24) within a rotating spindle (29). The pressure of the cutting liquid is measured by a pressure sensor (47). An air vent device (30) for opening and closing, with respect to atmospheric pressure, piping (3) that supplies the cutting liquid is provided above the rotary joint (28). A detection signal is inputted in the control board (70) from the pressure sensor (47), and when the control board (70) detects, after the pump (42) stops the supply of the cutting liquid to the piping (3), that the pressure of the cutting liquid does not decrease to a level lower than a predetermined threshold value, the control board (70) instructs the air vent device (30) to open the piping (4) to the atmosphere.

  • Publication number: 20140162175
    Abstract: A cathode-side gas flow path of a cell that forms part of a fuel cell is formed by a first expanded metal arranged on a gas inlet side, and a second expanded metal arranged on a downstream side. The first expanded metal is such that mesh is arranged in a straight line, and gas that flows on a gas diffusion layer side is separated from gas that flows on a separator side. The gas flowrate on the gas inlet side is reduced, so the amount of produced water that is carried away is reduced. As a result, the gas inlet side is inhibited from becoming dry at high temperatures.
