  • Publication number: 20150247793
    Abstract: A spectrophotometer includes: a sample-chamber lid capable of opening and closing an opening portion of a sample chamber for setting a sample and a reference sample; and sample-chamber lid opening-closing detecting means for detecting an opening-closing state of the sample-chamber lid, and the spectrophotometer is capable of controlling a measurement of a xenon flash tube as a light source, a spectroscope, a detector, an amplifier, an AD converter, a processor, a storage device, and a data display part. In the spectrophotometer, the light source is turned on after a state of the lid changing from an opening state to a closing state is detected in a sample-setting instruction state by the sample-chamber lid opening-closing detecting means; absorbancy, transmissivity, reflectivity, a sample-side energy value, or a reference-side energy value is measured; and a measurement result is displayed on the data display part.

  • Patent number: 9114400
    Abstract: A grinding type vertical grain milling machine is capable of shortening a dimension of a machine body in the vertical direction and removing bran by evenly suctioning an entire bran removing chamber. The grinding type vertical grain milling machine includes a bran removing metallic mesh cylinder with a main shaft, an integral grinding type grain milling roll body, a bran removing chamber, and a bran discharge pipe that discharges bran to the outside of the machine. A fan-pulley is provided between the bran removing chamber and the bran discharge pipe. The fan-pulley rotationally drives the main shaft to which the grinding type grain milling roll is axially attached and generates a bran removing wind to convey bran produced by the grain milling action of the grinding type grain milling roll from the bran removing chamber toward the bran discharge pipe.

  • Publication number: 20150160643
    Abstract: Using a machine tool, a workpiece is machined while periodically varying the rotational speed of a spindle thereof. Correlation data on correlation between a speed variation rate RVA of the spindle rotational speed, a speed variation period ratio RVF thereof, and vibration of a tool when machining the workpiece while periodically varying the spindle rotational speed is previously obtained. Based on the correlation data, the speed variation rate RVA and the speed variation period ratio RVF are set so that the vibration of the tool and machining accuracy are within their respective allowable ranges, and based on the set speed variation rate RVA and speed variation period ratio RVF, a variation amplitude and a variation period of the spindle rotational speed are determined. The spindle is rotated at the rotational speed varying at the determined amplitude and period with respect to a target rotational speed, thereby machining the workpiece.

  • Publication number: 20150120022
    Abstract: A training supporting system has a training supporting apparatus and an exercise form analyzing apparatus, the both apparatuses being connected to each other through a communication network. The training supporting apparatus is worn on the arm of a user and measures acceleration rates of motion of the user's body where the apparatus is fitted on, at least in the three directions along X-, Y- and Z-axes, while the user is walking or running. Receiving the measured acceleration rates from the training supporting apparatus through the communication network, the exercise form analyzing apparatus analyzes an exercise form including balance between arm swing and foot landing, and sends back the analysis result of the exercise form to the training supporting apparatus through the communication network.

  • Publication number: 20140365054
    Abstract: If the accelerator is on upon restarting a driving force source in travel mode by the time when the vehicle comes to a standstill after the driving force source is manually operated to stop while the vehicle is traveling, a control device for the vehicle implements first control in which the driving force output to the drive wheels is gradually increased. If the accelerator is on upon switching to the travel mode following restarting of the driving force source in the neutral mode and by the time the vehicle comes to a standstill after the driving force source is manually operated to stop while the vehicle is traveling, the control device implements second control in which the driving force output to the drive wheels is increased. The first control increases the driving force not as much as the second control increases the driving force.
