Abstract: Provided is a separation and recovery apparatus for continuously separating and recovering, from a resin mixture containing a resin containing a hydrolyzable polymer and a resin containing a nonhydrolyzable polymer, a hydrolytic component a of the hydrolyzable polymer A and the nonhydrolyzable polymer B, the apparatus including: a crushing unit that crushes the resin mixture a melting/discharging unit that melts a crushed product obtained by the crushing unit to form a fluid and discharges the fluid at a high pressure; and a hydrothermal reaction treatment unit that continuously subjects the fluid discharged from the melting/discharging unit to a hydrothermal reaction treatment, wherein, in the melting/discharging unit, the hydrolyzable polymer A is hydrolyzed, and the hydrolytic component a thereof is dissolved and transferred into water permeating a sintered alloy diaphragm, thereby separating the nonhydrolyzable polymer B.

Abstract: In accordance with an embodiment, an inkjet head comprises a head section, a clock signal generator, a drive controller and a current measurement section. The head section applies a drive voltage to a wall surface of an ink chamber and ejects ink from the ink chamber. The clock signal generatorsends a clock signal to the head section. The drive controller stops the clock signal sent to the head section, and applies a predetermined drive voltage to the head section. The current measurement section measures a current flowing to the head section while the drive controller stops the clock signal sent to the head section.

Abstract: An inkjet head includes a head unit, a storage unit, an identification circuit, and a driving control circuit. The head unit ejects ink. The storage unit stores print data. The identification circuit identifies a type of a head unit. The driving control circuit transmits the print data in an order corresponding to a type of the head unit which is identified by the identification circuit.

Abstract: A work management system has input means having a function of inputting coordinate information from the surface of a panel, output means having a function of projecting electronic information onto the panel, and data processing means for executing a predetermined processing, e.g., preparation and input processing of a form, a chart or a drawing, retrieval, editing, totalization, etc., by establishing a correspondence between the information projected on the panel by using the output means and the coordinate information input from the input means. The data processing means displays a list of registered items to be designated in a window for selection of one of the items, whereas, when coordinate information is input from two points for an entry column for time setting, the data processing means draws a bar between the two points. Control information which is conformable to working hours of equipment at a work site, e.g.
