Abstract: Provided is a production method for a soluble material, including: causing a solid raw material containing at least one component of a hydrolyzable material selected from the group consisting of a protein, a carbohydrate and a lipid, and a fibrous material, and water in an amount corresponding to 0.04 to 2.4 parts by weight with respect to 1 part by weight of a dry amount of the raw material to coexist; applying a shearing force in a state where heating and pressurization are performed at 200 to 374° C. and in a pressure range equal to or higher than a vapor-liquid coexistence curve of water to hydrolyze at least a part of the hydrolyzable material and/or to amorphize at least a part of the fibrous material; and halting the pressurization to cause adiabatic expansion.

Abstract: An inventory management system according to an embodiment comprises: a weight measurer configured to measure a weight of a shelf on which an item can be placed; and an RF tag configured to transmit a wireless signal including information related to the weight measured by the weight measurer in response to a read request from a wireless device, wherein the RF tag includes a transceiver configured to generate power by a received electromagnetic wave or magnetic field and transmit the wireless signal to the wireless device by using the generated power, a storage configured to store therein the information related to the weight measured by the weight measurer, and a controller configured to cause the transceiver to transmit the wireless signal including the information related to the weight stored in the storage to the wireless device.

Abstract: A measurement device includes a sensor unit capable of measuring a state of a measurement target, and a control unit configured to control the sensor unit. The sensor unit includes a measurement unit capable of measuring a voltage corresponding to the state of the measurement target, a first voltage comparison unit configured to determine whether or not the measured voltage is changed beyond a lower limit value of a predetermined voltage change, and a second voltage comparison unit configured to determine whether or not the voltage change is changed beyond an upper limit value of the voltage change. The control unit stops power supply to the sensor unit in a case in which it is determined in the first and second voltage comparison units that the measured voltage is not changed beyond the voltage change.

Abstract: A conveyance system conveys an article arranged by a user to a customer. The conveyance system includes a first conveyance unit for conveying the article arranged by the user, a second conveyance unit that is connected to the first conveyance unit and that is configured to convey the article conveyed from the first conveyance unit, and, when the user newly arranges a new article, is capable of conveying the article, a third conveyance unit that is connected to the second conveyance unit and is configured to convey the article conveyed by the second conveyance unit to the customer, and a control unit that is configured to perform conveyance control of each of the first conveyance unit, the second conveyance unit, and the third conveyance unit, and convey the article to the customer.
