Provided are an imprint mold having a plurality of recesses constituting a predetermined mold pattern, in which the imprint mold comprises a stack, comprising a plurality of mold base material layers and an etching stopper layer interposed between the mold base material layers, on a substrate, the stack has the plurality of recesses having different depths, the mold base material layer and the etching stopper layer are made of materials having etching selectivity for each other, and each of the plurality of recesses has a bottom surface on which the etching stopper layer is exposed, and technology related thereto.

Method for manufacturing imprint mold, imprint mold, mold blank, and method for manufacturing optical element

A camera includes: a distance measuring device for measuring an object distance; a photometry device for measuring an object brightness; a mode setting device for setting a self portrait photographic mode to set a photographic condition appropriate for photographing a photographer oneself holding the camera; and a controller for controlling to perform photographing without conducting at least one of the measurement by the distance measuring device and the measurement by the photometry device when the self portrait photographic mode is set by the mode setting device.

A novel cardiac assist blood pump is disclosed. The blood pump comprises a pump chamber, a pressurizing chamber provided adjacent to the pump chamber, a rotor chamber provided adjacent to the pressurizing chamber and an impelled positioned in the pump chamber, said pump being characterized in that the rotation shaft of the impeller means is provided with a first seal member having a skirt portion which is made of an elastomeric material and extends downward to cover the clearance between the rotation shaft and the first rotation shaft hole provided between the pump chamber and the pressurizing chamber and a second seal member similar to the first one which covers the clearance between the rotation shaft and the second rotation shaft hole provided between the pressurizing chamber and the rotor chamber; and tile pressurizing liquid is forced into the pressurizing chamber. The pressurizing liquid penetrates into the pump chamber through the clearance between the rotation shaft and the rotation shaft hole and lifts the skirt portion of the first seal member and the friction between the seal member and tile bottom of the pump chamber is prevented. Also the pressurizing liquid presses the skirt portion of the second seal member and thus prevents leakage of tile pressurizing liquid into the rotor chamber.

Blood pump

An extracorporeal blood pump which comprises a pump housing having a pump chamber defined therein, and a rotary vane assembly accommodated within the pump chamber and including a substantially conical rotary pedestal having a base surface and a conical surface, a plurality of vanes each having radially inner and outer ends, and a driven shaft connected at one end with the base surface of the pedestal. The vanes are mounted on the conical surface so as to extend radially outwardly from an axis of rotation of the pedestal with the radially inner ends of the respective vanes being spaced a predetermined equal distance from an apex of the conical surface while substantially depicting a circle coaxial with the axis of rotation of the pedestal. Each neighboring members of the vanes are equally spaced from each other in a direction circumferentially of the pedestal. The base surface has a diameter of 30 to 55 mm enough to substantially cover a surface area of a bottom wall surface which partly defines the pump chamber and confronts the base surface of the pedestal, whereas each of the vanes is in the form of a generally rectangular straight plate extending at an angle of inclination within the range of 20 to 50 degrees relative to an imaginary line tangential to the circle delimited by the radially inner ends of the respective vanes. An extracorporeal blood circulatory device utilizing the blood pump of the type referred to above and comprising a control console accommodating a drive motor for the blood pump is also disclosed.

Blood pump and extracorporeal blood circulating apparatus

There is disclosed an apparatus for detecting an occlusion of a liquid transfusion tube in which a pump section is provided in a liquid transfusion tube for connecting an infusion liquid container with a body infusion element. An occlusion of the liquid transfusion tube is detected according to an amount of displacement of the liquid transfusion tube displaceable under a pressure of a liquid transfused to the liquid transfusion tube by an operation of the pump section.
