Abstract: Provided is a bellows pump device that is able to reduce fall of a discharge pressure of a transport fluid during contraction operation of a bellows. The bellows pump device supplies pressurized air to a hermetic discharge-side air chamber thereby to cause a bellows disposed within the discharge-side air chamber to perform contraction operation to discharge a transport fluid, and discharges the pressurized air from the discharge-side air chamber thereby to cause the bellows to perform expansion operation to suck the transport fluid. The bellows pump device includes an electropneumatic regulator configured to adjust an air pressure of the pressurized air to be supplied to the discharge-side air chamber, such that the air pressure is increased so as to correspond to a contraction characteristic of the bellows during the contraction operation of the bellows.

Abstract: A resin-made pipe joint with enhanced sealing property between a joint body and sleeve. A sealing portion which seals between an inner circumferential surface of an inserting portion of a sleeve and an outer circumferential surface of an inner cylinder portion is formed by press-inserting an inserting portion into a groove portion of the joint body. When the inserting portion is press-inserted into the groove portion, a space is formed between a body cylinder portion located opposite to an opening portion of the groove portion in the axial direction, and the projection end of the inserting portion. After completing press insertion of the inserting portion into the groove portion, in a section including axis of the inner cylinder portion, a region in the outer circumferential surface of the inner cylinder portion facing the space forms an angle of 5° to 15° to the axis of the inner cylinder portion.

Abstract: In generating a virtual endoscopic image, an interior of a lumen is made viewable even when the viewpoint position is changed. A virtual endoscopic image generation element generates a virtual endoscopic image by volume rendering based on three-dimensional data. An opacity curve setting element sets an opacity curve which defines the relationship between pixel values of the three-dimensional data and opacity values. A viewpoint position setting element sets a viewpoint position of a virtual endoscopic image. A movement amount determination element determines a movement amount of the opacity curve with respect to an opacity curve at a reference viewpoint position. When a virtual endoscopic image is generated by the virtual endoscopic image generation element, the opacity curve setting element sets an opacity curve obtained by moving the opacity curve by the determined movement amount in the virtual endoscopic image generation element.
