Abstract: In one aspect, an improved craps system may comprise at least one camera and a dealer station having at least one dealer station memory, at least one dealer station display device, and at least one dealer station processor in communication with the at least one camera. The at least one dealer station processor may be configured to receive the information from the camera regarding the throw of dice and determine, based upon the information, whether the throw complies with one or more requirements for a proper throw of dice.

Abstract: A Method for manufacturing a liquid discharge head having a flow path forming member for forming a liquid flow path which communicates with a discharge port discharging liquid, comprises; preparing a layer containing a compound having a structure represented by Formula (1) and a structure represented by Formula (2) as a main chain on a substrate, providing a solution in which a resin is dissolved in a compound represented by Formula (3) or (4) on the layer, forming a mold having the shape as the flow path from the resin, providing a layer which will become the flow path forming member so as to cover the mold, and removing the mold to form the flow path.

Abstract: A process for producing an ink jet head, including forming an ink flow path pattern whose surface has been subjected to insolubilization treatment on a substrate having an energy-generating element, applying a UV curable flow path forming material on the pattern and substrate to form an ink flow path forming layer, irradiating part of the ink flow path forming layer with ultraviolet rays for development, thereby forming an ink ejection orifice, and removing the pattern, thereby forming an ink flow path. The step of forming the pattern includes applying a positive resist containing a resin having a phenolic hydroxyl group on the substrate to form a positive resist layer, patterning the positive resist layer to form an ink flow path pattern prior to insolubilization treatment, applying a coating agent containing a compound having two vinyl ether groups on the pattern, and heat-treating the pattern coated with the coating agent.

Abstract: To implement an ink tank and a printing apparatus that can detect a residual quantity of ink in an ink containing part optically with high accuracy by solving a problem of false detection of an ink residual quantity caused by irregular reflection light and scattered light generated by light from a light emitting part. For that purpose, the light source for emitting light of a first wavelength and the light receiving part for receiving light of a second wavelength are provided. Then the light of the first wavelength from the light source is configured to be irradiated on a luminescent material that is provided in the ink tank and emits the light of the second wavelength using an optical prism only when the ink does not exist in the ink tank.

Abstract: A method of manufacturing a liquid discharge head including a flow path forming member configured to form a flow path communicating with a discharge port to discharge liquid, includes, providing a first layer which includes a photosensitive resin and a light absorption agent on a substrate, and providing a second layer which includes a positive photosensitive resin but substantially does not include the light absorption agent on the substrate, so as to coat the first layer, forming a pattern having a shape corresponding to the flow path by performing a patterning process, and providing a layer which becomes the flow path forming member on the substrate, so as to coat the pattern. The method further includes forming the discharge port by performing a patterning process including exposure of the layer that becomes the flow path forming member, and forming the flow path by removing the pattern.

Abstract: A method for producing a liquid discharge head having a flow path wall member which includes walls of a liquid flow path communicating with discharge ports that discharge a liquid includes: preparing a substrate having a resin layer formed from a resin composition containing a polyhydroxystyrene-based resin in which the hydrogen atoms of phenolic hydroxyl groups are partially substituted with groups which are dissociable by acid, a compound having two or more vinyl ether groups, and a compound capable of generating a particular acid upon receiving energy from light; exposing the resin layer to light and removing exposed areas to form a pattern of the flow path from the resin layer; preparing a coating layer which serves as the flow path wall member; exposing the coating layer to light and removing unexposed areas of the coating layer to form openings that serve as the discharge ports; and removing the pattern.
