A compressor for a turbo chiller that can stably and efficiently operate in various operating states is provided. An aerodynamic feature map showing a rotating stall line at which rotating stall occurs is provided on a map represented by a flow parameter reflecting the volume flow based on the output thermal capacity of the chiller and by a pressure parameter reflecting the head based on the evaporator pressure and the condenser pressure. A minimum rotation speed obtaining unit obtains a minimum...

A drilling fluid additive employing at least one emulsifier and at least one titanate. Drilling fluids containing the above additive. A method of stabilizing a drilling fluid by employing the above additive.

A gore as a portion of a continuous elongated knitted fabric in a wale direction like a flared skirt is used. A knitted fabric formed by connecting a plurality of the gores in a course direction is designed. At the time of designing a pattern spread over a plurality of gores, the pattern is designed on the outer shape image as a composite image of the gores, and the design is divided into gores. At the time of assigning the pattern to the gores, it is checked whether any narrowing course is pres...

A connector has a housing (10) with a cavity (11) and a resiliently deformable lock (13) for locking a female terminal fitting (30) in the cavity (11). The lock (13) has a base (25) and a projection (26) that projects into the cavity (11) from the base (25). Both side surfaces (25b) of the base (25) are formed by a mold that is moved forward to open, and notches (17a) are formed in the front surface of the female housing (10) by this mold. The notches (17a) extend more outward than inner side su...

Coordinates in an image and its corresponding color-converted data are supplied to a control/operation portion for every pixel. Quantization is applied to each color. The quantization is carried out so that a kind of dot for at least one color is made different from kinds of dots for the others in one and the same pixel when dots for different colors are superimposed on the pixel. The control/operation portion refers to a two-dimensional matrix on the basis of the quantization result, determines...

A dirt runner, such as those used on street sweeping machines and the like, and a flexible support for the dirt runner to be attached to a housing portion. Flexible supports such as elongate strips of elastomeric material are fastened along the upper portion of the strips to the housing portion of the machine and the dirt runner is fastened along the lower portion of the elastomeric strip. The dirt runner is adequately supported to be driven in its longitudinal direction of travel and more freel...

An artificial fishing lure has an oval shaped cylindrical body section. A plurality of rib members are formed around the outer perimeter of the body section. The plurality of rib members are for preventing the fishing lure from slipping out of a mouth of a fish. A tail section extends from an end of the body section. The tail section is split horizontally down the center of the tail section to allow each half of the tail section to separate and then come back together in a pinching motion when t...

An enclosure for enclosing piezoelectric elements of a piezoelectric actuator comprises a side wall that is shaped to define at least one strain compensation formation selected from a longitudinally-extensible part at which the side wall can be extended or contracted parallel to a longitudinal axis of the enclosure; and an inwardly-deflectable part at which the side wall can be deflected transversely to the longitudinal axis.

A method of forming and a blank therefor, in which the blank comprises a parent body and an insert, at least one of which is made of a material which possesses superplastic properties. The insert is joined to the parent body by friction stir welding. The primary purpose of the invention is to provide a blank for a forming process during which some parts of the blank are required to deform to an extent which requires superplastic properties, whereas the remaining parts of the blank are deformed t...

An improved cartridge for use in hypodermic syringes is disclosed in which the hollow tubular cartridge body has a first end which has a resilient seal thereon and which engages both the end of the cartridge and a portion of the periphery thereof adjacent the end. The first seal member is also capable of engaging the internal nozzle of the syringe, if one exists, as well as engaging the inner surface of the barrel of the syringe. The opposed end of the cartridge body, which is normally contacted...
