The metal component includes a through-hole penetrating the metal component from the first main surface to the second main surface.

Metal component and ceramic substrate

A substrate fixing device includes a baseplate, an electrostatic attraction member, and an electrode pin. The baseplate includes a metallic member in which a through hole is famed. The electrostatic attraction member is over a surface of the baseplate and includes an attraction electrode. The electrode pin is inserted through the through hole to be connected to the attraction electrode. A recess communicating with the through hole is formed in the surface of the metallic member with the through hole being within the recess in a plan view from a direction perpendicular to the surface of the metallic member.

Substrate fixing device

A substrate fixing apparatus includes: a base plate; an electrostatic adsorption member that adsorbs and retains a substrate; a support member that is disposed on the base plate to support the electrostatic adsorption member; and an adhesive layer that adhesively bonds the electrostatic adsorption member to the base plate. The support member directly contacts the base plate and the electrostatic adsorption member. An elastic modulus of the support member is higher than an elastic modulus of the adhesive layer.

Substrate fixing apparatus including a base plate, an electrostatic adsorption member, a plurality of support members on the base plate and supporting the electrostatic adsorption member, and an adhesive layer bonding the electrostatic adsorption member to the base plate

Three nozzle arrays respectively including a plurality of nozzle orifices are provided. Two of the nozzle arrays are divided into a plurality of nozzle blocks NB to NB . One of the nozzle arrays is provided as a unit nozzle block NB . Different kinds of inks to be ejected are allocated with respect to each nozzle blocks. Dye-family colored inks are ejected from the respective divided nozzle blocks. Pigment-family black ink is ejected from the unit nozzle block.

In carving a decorative groove ( ) formed in V-shape cross section extending from inside to outside on a dial plate ( ) of a timepiece as a decorative plate, the slant angle of an inner slanted side ( A) forming the V-shape of the decorative groove ( ) is made gentler than an outer slanted side ( B) at an inner part of the spiral, so that action of light reflected on the flat surface of the dial plate ( ) macroscopically becomes similar to the light reflected on a bulging surface to give the central portion of the dial plate ( ) a bulging appearance, whereby a three-dimensional effect is provided by the decorative groove ( ) even when the dial plate ( ) is made of a thin plate, thereby adding depth and a luxurious touch or aspect.

An ink jet recording apparatus for ejecting droplets of ink from a plurality of nozzles is provided. The recording apparatus comprises a nozzle plate having the plurality of nozzles and a pressure generator associated with each of the plurality of nozzles. The nozzles and said pressure generators are disposed in at least three groups and each of the groups are associated with a single color ink. The ink associated with one group of nozzles and pressure generators is lighter, and the ink associated with one group of nozzles and pressure generators is darker than the ink associated with the other groups of nozzles and pressure generators. The group of nozzles and pressure generators associated with the ink of the lightest color is situated furthest from the group of nozzles and pressure generators associated with the ink of the darkest color. The recording apparatus also comprises first reservoir means for storing ink formed between the nozzle plate and the pressure generating means having a first cross-sectional area, support means for supporting the pressure generating means and having a slit having a second cross-sectional area for supplying ink to the first reservoir means, and second reservoir means in fluid communication with the slit for storing ink having a third cross-sectional area wherein the first cross-sectional area is smaller than the second cross-sectional area and the second cross-sectional area is smaller than the third cross-sectional area for promoting capillary action in ejecting droplets of ink through the plurality of nozzles.

Ink jet recording apparatus and method of manufacture

A thermal ink jet recording apparatus includes at least a substrate having at least a plurality of heating elements disposed in rows in at least two groups. Each group consists of two rows of heating elements, one row arranged on either side of the ink supply portion, each of the groups of the heating elements being associated with a single color ink. At least one nozzle plate has a plurality of nozzles disposed on the substrate where at least one nozzle plate and the substrate define a space between the nozzle plate and the substrate in registration with each group of heating elements and corresponding group of nozzles associated with a single color ink. Means are provided for independently delivering ink of one color from the ink reservoir to each of the spaces, whereby printing can be independently effected in at least two colors of ink.
