A liquid ejection head including a recording element substrate for ejecting liquid supported by a support member with an adhesive layer provided between the recording element substrate and the support member. A terminal is provided at an end portion of the recording element substrate with a sealing member covering the end portion of the recording element substrate including the terminal. The sealing member is in contact with a side surface of the end portion and an end surface of the adhesive layer. The adhesive layer comprises includes a first adhesive portion and a second adhesive portion positioned between the first adhesive portion and the sealing member. Rigidity of the second adhesive portion is less than the rigidity of the sealing member and less than the rigidity of the first adhesive portion.

Liquid ejection head

The present invention provides a microfluidic device which is molded with a die and has a specimen inlet part. The microfluidic device has the specimen inlet part. The specimen inlet part has an inlet channel for introducing a specimen into the flow channel, wherein the inlet channel has a diameter which continuously and gradually increases as the inlet channel approaches the flow channel, or has a diameter which is constant in the vicinity of an inlet port and then continuously and gradually increases as the inlet channel approaches the flow channel.

Microfluidic device

In an electron beam apparatus including an electron emission element and an anode, the electron emission element includes a gateand a cathodehaving a projection portion. The gateand the cathodeare located in a surface of an insulating memberincluding a recess. The projection portion of the cathodehas a height distribution, and an average value dav (m) of a shortest distance between the gateand the projection portion of the cathodeand a difference h (m) between the average value dav and a shortest distance dmin (m) from the gateto a maximum convex portion of the projection portion of the cathodesatisfy a relationship of h/dav&#x3c;0.39.

Electron beam apparatus and image display apparatus therewith

An image forming apparatus in which a first substrate provided with an electron-emitting device and an image displaying member which electrons emitted from the electron-emitting device irradiate are arranged to be opposed is provided with a deflecting means deflecting the electrons emitted from the electron-emitting device and a trapping unit trapping an inert gas ionized by the electrons. Thereby, the damages of the electron-emitting device by the inert gas are prevented, and the life of an image display apparatus is aimed to be elongated.

Image forming apparatus with reduced loss of electron source caused by the inert gas

In an image display apparatus, by providing an insulating member which covers an electroconductive member existing in a region out of an electron beam emitting region, an unnecessary discharge from the electroconductive member is suppressed and a damage due to the discharge is prevented, thereby realizing a long life of the apparatus.
