A fluid injector for x-ray tubes and a method to provide a liquid anode by liquid metal injection, wherein the fluid injector includes a device to inject fluid from an opening in a chamber of the device as a fluid jet generated by an arrangement to change the volume within the chamber, and includes a reservoir to store the anode material, which is fluidically connected by a pipe with the chamber of the device, where the pipe has a part formed in the fluid flow direction that is shaped to block fluid flow from the chamber to the reservoir during injection, and where the includes injecting fluid in a direction towards an electron beam and refilling the chamber with liquid metal from the reservoir.

Provided is a sanitary cleansing device configured to provide a feeling of comfort and satisfaction to a user by simple operation. The sanitary cleansing device (1) includes a nozzle assembly (6) provided with a spray port, an operation device (10) operated by a user to start spraying of the cleansing water from the spray port, and a spray control device (20) configured to execute a fixed spot cleansing mode and a stop sequence based on operation of the operation device. The fixed spot cleansing mode is a cleansing mode for stopping the spray port at a reference private area position at which the cleansing water is splashed on a private area position of the human body, and the stop sequence is a sequence of stopping spraying of the cleansing water after execution of a series of cleansing modes set in advance.

A nozzle for spraying materials, in particular dispersions, emulsions or suspensions, comprising a nozzle body having a nozzle mouthpiece.

Methods for controlling or regulating the volume flow rate of a substance to be sprayed and/or a gas from a nozzle suitable for spraying substances, particularly dispersions, emulsions or suspensions, wherein the nozzle has a nozzle body comprising a nozzle mouthpiece, wherein the nozzle body has an inner pipe, which is connected to a supply for the substance to be sprayed and has an inner wall and a discharge port, and an outer pipe, which is spaced from the inner pipe, is connected to a supply for a gas and has a discharge port, and the discharge port of the inner pipe and the discharge port of the outer pipe are arranged in the region of the nozzle mouthpiece.

The invention relates to a nozzle (101, 201, 301, 401, 501, 601, 701, 801, 901, 1001) for spraying substances, in particular dispersions, emulsions or suspensions.

Please replace the Abstract at page 41 with the following replacement paragraph: A nozzle, for spraying materials, in particular, dispersions, emulsions, or suspensions.

An inkjet coating machine is provided to prevent the components in the paint from precipitating. The inkjet coating machine includes: a robot arm having a chuck at a front end and a nozzle head unit detachably mounted on the chuck. The nozzle head unit includes a nozzle head having a nozzle for spraying the paint, a nozzle control unit for controlling driving of the nozzle, and a head-side circulation path enabling the paint to circulate within the nozzle head. The nozzle head, the nozzle control unit and the head-side circulation path are integrally configured. The coating machine further includes a standby holding unit that holds at least one nozzle head unit in standby and a head replacement unit that replaces the nozzle head unit.

Provided is a system and method for rapidly cleaning a surface utilizing a plurality of quick exhaust valves wherein the system is configured for particularly cleaning large or cylindrically shaped surfaces of sensors mounted to an exterior of a vehicle. The system and method contemplate the use of a plurality of quick exhaust valves arranged with at least one nozzle and at least one solenoid valve to efficiently express a dose of pressurized air onto the surface.

The present invention relates to devices and methods for coating surfaces including surfaces of medical devices, in particular the coating of microprojections on microprojection arrays. The present invention also relates to print head devices and their manufacture and to methods of using the print head devices for manufacturing articles such as microprojection arrays as well as to coating the surfaces of microprojection arrays. The present invention also relates to high throughput printing devices that utilize the print heads of the present invention.

A liquid discharge apparatus includes a liquid discharge head that discharges a liquid from multiple nozzle holes to apply the liquid to an object and circuitry that causes the liquid discharge head to discharge the liquid from a first number of the multiple nozzle holes to a first area at a start of an application of the liquid to the object as a first discharge, discharge a first total amount of the liquid to a receptacle different from the object before the first discharge as a first dummy discharge, discharge the liquid from a second number of the multiple nozzle holes to a second area at the start of the application as a second discharge, discharge a second total amount of the liquid larger than the first total amount to the receptacle before the second discharge as a second dummy discharge. The second number is larger than the first number.
