Abstract

Provided is a novel inkjet recording device capable of preventing an ink droplet from being attached and fixed to a bent pipe part formed at a gutter. Aside from air flowing in from an inflow opening 36 of a gutter 29, secondary air is supplied to a bent region 34 bent of a bent pipe part 34 in the same direction as a flow of air flowing out from the side of an outflow 34 out of the bent pipe part 34. Since a flow rate of an air flow in an inner peripheral surface region 40 on an inner side of the bent pipe part 34 can be increased by the secondary air, an ink droplet can be prevented from being attached and fixed to the bent pipe part 34 formed at the gutter 29.

The control unit 2 performs coasting control for controlling the voltage generation device 3 to output a voltage for suppressing an induced voltage of the permanent magnet synchronous motor 4 to the permanent magnet synchronous motor 4 when inflow of a current from the permanent magnet synchronous motor 4 to the voltage generation device side is detected while control of an output stop of a driving voltage for driving the permanent magnet synchronous motor 4 is performed. During the coasting control, the control unit 2 sets the torque command value to a coasting control time torque command value which is a positive value corresponding to the increase of a rotational frequency of the permanent magnet synchronous motor 4.

The present invention addresses the problem of specifying a period of time until a backup product will be delivered to a customer that has signed a contract for rapid delivery of a backup product. A computer: issues to a vendor a reservation for a backup product for replacing a device contained in a site operated by the vendor; when a request for replacement of a device is acquired from a vendor having a reservation, checks whether the backup product is in stock; if the backup product is not in stock or the like, acquires a replenishment delivery period for a new backup product from a manufacturing company; and calculates a period of time until the backup product will be delivered to the vendor's site.

Abstract

The present invention makes it possible to change the contrast of an image, from the global resolution contrast to the low-resolution contrast, without significantly changing the local high-resolution contrast of the image. An input image 200 is subjected to a block-level reference image preparation process 250 to prepare block-level reference images 220-223, and in the block-level reference image preparation process 250 the input image 200 is divided into the same blocks used in preparation of block integration images 214-217, thereby preparing low-resolution images in which the resolution of each block image has been lowered. By means of a low-resolution contrast replacement consolidation process 271, the block-level values of the block-level reference images 220-223 are replaced with the low-resolution contrast of each block integration image 214-217 on a block-by-block basis, thereby changing the contrast of the block integration images 214-217 on a block basis, and a weight-averaged output image 234 is prepared.

Prior art has a problem that as there is a difference in communication delay time between going and returning communication paths due to packet congestion in a network configuration using a network relay device, it is impossible to synchronize the times of day. In order to solve the above problem, the present invention controls a time synchronization unit 131 by a time synchronization control unit 130 and thereby synchronizes the times of day once, then calculates the delay of a time packet in an outward path and an inward path on the basis of the synchronized time of day and executes a time synchronization process using the time of day of the time packet when the calculated values are equal.

Abstract

The present invention enables analysis work to be performed even if one is not an expert with sufficient underlying knowledge regarding scattering bodies, and makes automating analysis easy. One preferable aspect of the present invention is a device that calculates a spatial parameter distribution indicating a spatial structure of a sample on the basis of a scattering pattern, which is a projection of the spatial structure of the sample to a wave number space and which is obtained as a result of detecting scattering of a particle beam, which interacts with the sample, entering the sample. The device has an interaction estimation unit that performs estimation by associating a point on the spatial parameter distribution of the sample at which there is interaction, during the scattering process, with a signal on the scattering pattern. In addition, the device has a parameter distribution calculation unit that aggregates the estimation results of the interaction estimation unit, and calculates a spatial parameter distribution of the sample matching the aggregated results. In addition, the device has a spatial parameter accuracy improvement calculation unit that improves the spatial parameter distribution estimation accuracy by alternately performing, multiple times, the estimations of the interaction estimation unit and the calculations of the parameter distribution calculation unit. This particle beam measurement results analysis device is characterized by being configured as described above.
