An elevator according to an aspect of the present invention includes a car speed detection device that measures car speed, an emergency braking device that comes into press contact with a guiderail and emergently stops a car when the car speed exceeds a threshold, an electric actuating unit that electrically actuates the emergency braking device, a battery that supplies electric power when commercial power supply is interrupted, and a safety control unit that monitors abnormality of the elevator and controls operation of the electric actuating unit. The safety control unit measures remaining power of the battery when the electric power is supplied from the battery, determines operation propriety of the emergency braking device at commercial power supply restoration time based on transition of battery remaining power, and controls operation of the electric actuating unit at the commercial power supply restoration time based on content of the determination.

Elevator and control method for elevator

A control system for an elevator includes a first car speed detection device and a second car speed detection device to measure a moving speed of the car, a hoist brake to apply braking to the hoist, emergency stop equipment to brake the car by grasping guide rails, and a control device to control the hoist, the hoist brake, and the emergency stop equipment based on outputs of the first car speed detection device and the second car speed detection device. If two pieces of velocity data that have been output from the first car speed detection device and the second car speed detection device respectively differ from one another and acceleration data of the car calculated from one that is higher of the two pieces of velocity data is equal to or more than a predetermined threshold, the control device decides if either car speed detection device is abnormal.

Control system for elevator

Shading of a site other than a site of interest is disabled to allow construction of a visually good three-dimensional image even when the site other than the site of interest is displayed in a translucent manner. An ultrasound diagnostic apparatus includes a sending section that sends an ultrasonic wave to a diagnosing object via an ultrasound probe, a receiving section that receives a reflected echo signal from the diagnosing object, a three-dimensional elasticity image constructing section that performs volume rendering with shading on elasticity volume data with an elasticity value based on the reflected echo signal to construct a three-dimensional elasticity image, and an image display section that displays the three-dimensional elasticity image. The three-dimensional elasticity image constructing section performs the volume rendering using an elasticity opacity according to the elasticity value and disables the shading of a portion with the elasticity opacity with a predetermined value.

Submerged nozzle for continuous casting apparatus

To provide an ultrasonic diagnostic apparatus capable of producing a three-dimensional image of an object for an organ region within a range of elasticity values desired by an operator and allowing the operator to recognize the region easily, elasticity value data included in a desired elasticity value range among elasticity value data constituting a volume data are selected and rendered. Whereby, a three-dimensional elasticity image in the set elasticity value range is produced. An area corresponding to the elasticity value range is displayed on at least one of a two-dimensional elasticity image and a section image.

An ultrasonic diagnostic apparatus has a storage unit for storing the elastic volume data generated on the basis of the ultrasonic image data obtained by transmitting/receiving ultrasonic waves to/from an object to be examined, an input unit for setting a region of interest in the space which is occupied by the elastic volume data, an extraction unit for extracting from the elastic volume data a voxel group having the voxel values within a set elasticity range which is set based on the elasticity value of the voxels in the region of interest, a 3-dimensional elastic image creation unit for generating a 3-dimensional elastic image basis on the elastic volume data of the voxel group which is extracted by the extraction unit or the elastic volume data excluding the extracted voxel group; and an image display unit for displaying the 3-dimensional elastic image generated by the 3-dimensional elastic image creation unit.

Ultrasonic diagnostic apparatus

Provided is an ultrasonic diagnostic apparatus which constructs a three-dimensional elastic image by separating elastic volume data and then performing volume rendering, and also provided is an ultrasonic image display method. The three-dimensional elastic image constructing unit separates the elastic volume data into a plurality of data sets on the basis of the elastic values and performs volume rendering on the separated elastic volume data sets, thereby constructing a three-dimensional elastic image.

Ultrasonic diagnostic apparatus and ultrasonic image display method

Provided is an ultrasonic diagnostic apparatus capable of clearly depicting areas of noteworthy hardness. In order to clearly depict 3-dimensional elasticity images of the area of noteworthy hardness, frequency is counted for each magnitude of the elasticity value for the elasticity data configuring the volume data, and elasticity values in a prescribed range which is determined on the basis of frequency, are converted to be large and elasticity values outside the prescribed range are converted to be small. By rendering the post-conversion volume data, the large elasticity values of areas of noteworthy hardness are integrated and 3-dimensional elasticity images are generated.

An object of the invention is to provide a casting nozzle in which attachment and deposition of alumina or the like can be prevented while a drift of molten steel can be prevented.
