Abstract: A compressor body includes a compression mechanism including a screw rotor that compresses gas, a casing that accommodates the compression mechanism and defines a compression working chambers therein, a suction side bearing that rotatably supports the screw rotor, a bearing chamber that accommodates the suction side bearing, and a liquid supply port that communicates with the compression working chambers and supplies liquid supplied from the outside of the casing into the compression working chambers. The casing has an internal liquid supply flow path that extends from a discharge side of the compression working chambers as an upstream side to a suction side of the compression working chambers as a downstream side and that supplies the liquid to the liquid supply port. The internal liquid supply flow path has a downstream portion reaching the bearing chamber and supplies the liquid to the suction side bearing.

Abstract: An arithmetic processing device includes one or more processors configured to compare a sign of first data and a sign of second data for each of data pairs of the first data and the second data, control writing and reading of the data pairs to a first and second buffer, the first buffer preferentially holding a first data pair whose signs match than a second data pair whose signs do not match, execute a multiply-accumulate operation of data pairs sequentially output from the first buffer and data pairs sequentially output from the second buffer in parallel, add operation results, and set an output value to 0 in a case where the number of the first data pairs is smaller than the number of the second data pairs, and a result of the addition when the multiply-accumulate operation of the first data pair is completed is 0 or less.

Abstract: A first correction signal creation unit splits an angular velocity signal of an ultra low-low frequency band from an angular velocity signal of an X-axis angular velocity sensor and outputs a first correction signal amplified based on signal output characteristics of the angular velocity sensor. A second correction signal creation unit splits an angular velocity signal of a low-high frequency band from the angular velocity signal and outputs a second correction signal amplified based on the signal output characteristics of the angular velocity sensor. An addition computation unit creates a composite correction signal in which the first correction signal and the second correction signal are composed, and a drive computation unit creates a drive signal based on the composite correction signal. A driver drives the X-axis actuator based on the drive signal, displaces the correction optical element, and corrects shake of an image.

Abstract: A first correction signal creation unit 78 splits an angular velocity signal of an ultra low-low frequency band from an angular velocity signal of an X-axis angular velocity sensor 36 and outputs a first correction signal amplified based on signal output characteristics of the angular velocity sensor. A second correction signal creation unit 79 splits an angular velocity signal of a low-high frequency band from the angular velocity signal and outputs a second correction signal amplified based on the signal output characteristics of the angular velocity sensor. An addition computation unit 98 creates a composite correction signal in which the first correction signal and the second correction signal are composed, and a drive computation unit 99 creates a drive signal based on the composite correction signal. A driver 74 drives the X-axis actuator 38 based on the drive signal, displaces the correction optical element, and corrects shake of an image.

Abstract: A process of measuring a shape while changing the relative posture of an microscopic interferometer to a sample lens which is rotated about a rotation axis is divided into a process of measuring a top surface in a state where the sample lens is supported from a back surface and a process of measuring a back surface in a state where the sample lens is supported from the top surface. By combining first shape information of a flange side surface acquired by the process of measuring the top surface and second shape information of the flange side surface acquired by the process of measuring the back surface, the relative positional relation between the sample top surface and the sample back surface is calculated.

Abstract: A paper winding device for winding up photographic paper after exposure on a take-up spool in a photographic printer. A loop forming portion for storing exposed portion of the photographic paper in the form of a loop is disposed before the take-up spool. The take-up spool is rotated by a DC motor which is activated or inactivated depending on the amount of the loop. A paper guide arm is provided to confine the outermost convolution of the paper roll wound on the take-up spool. An angle detector detects the inclination of the paper guide arm to determine the paper roll diameter. The DC motor is dynamically braked after inactivated, and resistance value or braking time for dynamic braking of the DC motor is changed in accordance with the paper roll diameter, to reduce variation in paper winding amount with paper roll diameter in the delay time from the inactivation to the actual stop of the DC motor.
