Abstract: There is a need for improving the accuracy of estimating a gain error for an angular velocity sensor. An error estimation section and a correction section are provided as well as a gyroscope that detects an angular velocity of a vehicle. The error estimation section assumes the gain error of the gyroscope to be a state quantity and finds an estimated value for the gain error using a Kalman filter. Based on the gain error found by the error estimation section, the correction section corrects a gain correction amount used for gain correction of values detected by the gyroscope. The correction section corrects the gain correction amount dedicated to right turn based on the gain error found by the error estimation section when the vehicle is assumed to turn right. The correction section corrects the gain correction amount dedicated to left turn based on the gain error found by the error estimation section when the vehicle is assumed to turn left.

Abstract: In a specimen pre-treatment apparatus, a specimen support part is screwed in a hollow column casing part while facing a specimen support end toward the same direction as an open end of the hollow column casing part. A specimen holder is arranged so that the specimen support end which supports a specimen is opposite to an end portion of an anode (electrode). The change of the screwing depth can adjust a position of the specimen support part with respect to the hollow column casing part. Accordingly, it allows adjusting the distance between the specimen that is supported by the specimen support part and the end portion of the anode.

Abstract: A polymer composite comprises a base material, and a polymer membrane provided on at least a part of the base material, the polymer membrane having at least hydrophilicity, and the polymer composite is used in a state exposed to water or a water-based solvent. The polymer membrane is a resin film formed by photo-crosslinking a photosensitive resin composition consisting essentially of a water-soluble polymer, and during crosslinking of the photosensitive resin composition, some of photosensitive groups of the photosensitive resin composition are bound to amino groups fixed to the surface of the base material, whereby the resin film is fixed to the base material.

Abstract: The invention provides a glow discharge optical emission spectrometer for intermittently applying a high frequency voltage to a sample and obtaining a measured value from a spectroscope in synchronization with a timing of a unit of application during intermittent application. The obtaining of measured values in which is introduced noise at a non-application time during intermittent application is prevented, and by applying a high voltage value to the sample with a minimized adverse effect on a voltage application to the sample, high-level measured values are obtained. By obtaining a measured value a plural number of times during a unit of application, a large number of measured values are obtained in a short period of time, resulting in a reduction in measurement time.

Abstract: A glow discharge drilling apparatus enables switching of a continuous mode for continuously supplying electric power and an intermittent mode for intermittently supplying electric power. Electric power is supplied in the intermittent mode with respect to a sample easily melted by a heat due to a glow discharge and a sample easily broken by a force of sputtering due to a glow discharge or the like, whereby the sample is drilled so that an observation face capable of carrying out good observation can be obtained. When the sample is not easily melted and easily broken, the sample is drilled so that a good observation face can be efficiently obtained by supplying electric power in the continuous mode.

Abstract: The present invention discloses a system for analyzing elements contained in a sample in very slight amounts, such as C, S, O, N, H and the like in materials, such as steel and ceramics. An element analyzer can gasify the sample elements in an appropriate gas, such as oxygen gas in a high-frequency heating furnace or an electric resistant furnace. Resulting gas can be introduced into a mass spectrometer to permit a quantitative analysis of the sample elements. A metal sample can be levitated and heated and melted with induction current for producing the resultant gas for introduction to a mass spectrometer.

Abstract: A rotary actuator has a cushion mechanism for stopping a vane at a rotational terminal end position in a cushioning manner. The cushion mechanism has first and second openings. The first opening discharges an exhaust air pressed out from a cylinder hole by a rotating vane to an external portion without limiting a flow amount. The second opening discharges the exhaust air to the external portion in a state of limiting a flow amount. A flow amount adjusting mechanism connects to the second opening. The first opening is provided at a position sealed by the vane before the vane of a hole surface in the cylinder hole reaches a rotational terminal end position. The second opening is provided at a position which is not sealed by the vane after the vane reaches the rotational terminal end position.
