Abstract

A structure according to an embodiment includes a first substrate including a first valve and a second substrate joined to the first substrate. The structure includes a region where the first valve and the second substrate are not joined. A sticking suppressing section is provided in at least one of the first valve and the second substrate in the region. By configuring the structure in this way, it is possible to suppress sticking of the first valve to the second substrate in the structure including the first substrate including the first valve and the second substrate joined to the first substrate.

First claim

What is claimed is:

1. A structure comprising:
a first substrate including a first valve; and
a second substrate joined to the first substrate and including a suction port or a discharge port, wherein
the structure includes a region where the first valve and the second substrate are not joined, and
a sticking suppressing section is provided in at least one of the first valve and the second substrate in the region,
wherein a force developing section in which a force is applied to the first valve in a direction in which the first valve is pressed toward the second substrate is provided in the region.

2. The structure according to claim 1 , wherein the force developing section is configured integrally with the sticking suppressing section.

3. The structure according to claim 1 , wherein the force developing section is configured separately from the sticking suppressing section.

4. A diaphragm-type compressor comprising:
a substrate, which is the structure according to claim 1 ;
an actuator; and
a diaphragm provided between the substrate and the actuator,
the substrate, the actuator, and the diaphragm being laminated, wherein
in a direction of the lamination, the substrate includes a thick plate section and a thin plate section, and
the diaphragm is joined to the thick plate section and separated from the thin plate section.

5. A cooler comprising:
the diaphragm-type compressor according to claim 4 ;
a heat exchanging section configured to radiate heat of a coolant that rises in temperature by being compressed by the diaphragm-type compressor; and
a coolant expanding section configured to expand the coolant.

6. A projector comprising the cooler according to claim 5 , wherein
a light source or an optical element is coupled to the cooler via a secondary coolant pipe.
