Abstract: A pump with high performance and cleanability includes a casing having a smaller volute and a larger volute; a space between an outer circumference of an impeller and a starting end of the smaller volute being greater than that of the larger volute, generating a circulating flow of self-priming water from the smaller volute to the larger volute; and a diffusing part of the larger volute being formed into an upright, cylindrical self-priming water separating chamber guiding the self-priming water from the smaller volute to flow in for air-water separation. An inner circumference part of the casing is formed concentric with the outer circumference of the impeller with a predetermined space therebetween; defining members are protrusively disposed on the inner circumference part of the casing so as to define the shapes of the two volutes; and the self-priming water separating chamber is made attachable to and detachable from the casing.

In the gas-liquid dissolving tank that promotes dissolution of gas mixed with liquid in the liquid, openings that pass the flowing gas-liquid are formed at an upper portion and a lower portion of a container of the tank, a plurality of separation walls that vertically divide a plurality of chambers are disposed in the container, openings that connect upper and lower chambers are formed through the separation walls, the upper ends of the openings of the separation walls extend predetermined distances upward from the separation walls, and the lower ends of the openings of the separation walls extend predetermined distances downward from the separation walls.

Abstract: The server apparatus is applied to a game system which has a storage unit storing gaming dynamic images different from each other in association with a stream ID for identifying each gaming dynamic image. The game system acquires a playing dynamic image photographed by a portable phone and a stream ID of the playing dynamic image via a network. Base on the acquisition result, the game system determines the gaming dynamic image whose stream ID corresponds to the stream ID of the playing dynamic image acquired as a target gaming dynamic image, and provides a dynamic-image delivery service so that a delivery screen is displayed at each personal computer, the delivery screen including a composite dynamic image where the playing dynamic image and the target gaming dynamic image are synthesized.

Abstract: A ball valve includes a valve hole provided in an engine body to communicate with an inner end portion of a breather hole and is open in the engine body. A valve seat is formed on an inner surface of the engine body to coaxially surround the valve hole. A guide sleeve is in coaxially communication with the valve hole and the valve seat and is secured to the engine body at one end portion. A metallic valve element, formed to be ball-like with a predetermined weight is received to be rollable in the guide sleeve for enabling the closing of the valve hole and to be prevented from falling off the other end of the guide sleeve, is provided in the engine body so that the valve hole is placed within a moving range of oil in the engine body depending on the inclination of the engine body.

Abstract: An image forming apparatus has a sheet reading portion, an assimilation surveying portion, a color changing portion, and a printing portion. The sheet reading portion reads image data from a transparent sheet tinted with a predetermined color owned by a user. The assimilation surveying portion looks for, out of printable colors, a particular color that assimilates to the color of the read image data. The color changing portion changes, out of the data of a predetermined document accepted from the user, the color of the data of a concealable character, which is a character concealed when overlaid with the transparent sheet, to the found particular color. The printing portion prints, out of the data of the document, the data of the concealable character in the particular color.

Abstract: The object lens 21 and the ocular lens 22 are disposed in the lens barrel unit 11 and the relay lens system 23 is disposed therebetween. The image sensor 31 is disposed in the camera unit 12 and the coaxial illumination unit 32 is disposed therearound. The focus position shift member 25 is disposed at the image formation position L1 in the lens barrel unit 11. The light from the coaxial illumination unit 32 is imaged at the image formation position L1 and is shifted to a position L2 by the focus position shift member 25. Since the position L2 positions at a position closer than a focus position, light through the object lens 21 diffuses to illuminate the object 51.
