An adapter which controls rotation of a microscope on which a slide is placed and an imaging unit and which easily performs correction of a rotation shift is provided. The adapter includes a first connection member connected to a microscope, a second connection member connected to an imaging unit, a rotation member arranged between the first and second connection members and configured to rotate the second connection member relative to the first connection member using optical axes of the microscope and the imaging unit at a center, a control member configured to be fixed on one of the first and second connection members and control the rotation of the connection member, and a driving member configured to be engaged with the first connection member or the second connection member and change a position of the second connection member relative to the first connection member around the optical axes.

Adapter, microscope adjustment method, microscope system, and storage medium

A microscope system includes a microscope body, a camera connected to an observation optical system of the microscope body, and an XY stage on which a slide of an observation object is placed and which is configured to move in an X-axis direction and a Y-axis direction that are orthogonal to each other. The XY stage includes an XY two-dimensional scale plate. The XY two-dimensional scale plate includes a first mark configured to provide X-axis direction axis information and Y-axis direction axis information of the stage, and a second mark which is provided within an observable region of the camera on the same plane as the first mark and which is available for recognizing a position of an XY plane of the first mark in a Z-axis direction at each of a plurality of points by focus detection of the camera.

Microscope system

A slide used for observation by a microscope includes a label area configured to arrange a label, a cover glass area configured to arrange an observation object and a cover glass, a position reference mark arranged in a vacant area between the label area and the cover glass area and configured to specify a reference position of the slide and an X-axis direction and a Y-axis direction that are orthogonal to each other, and focus reference marks in which a predetermined pattern is repetitively arranged along two opposing sides of four sides of a periphery of the cover glass area, the focus reference marks being configured to specify a Z-axis direction orthogonal to the X-axis direction and the Y-axis direction.

Slide, set of slide and cover glass, and microscope system

A stage apparatus includes a plate-like stage plate having a spread in a first direction and a second direction intersecting with the first direction and a plate member having a linear expansion coefficient different from that of the stage plate. The stage apparatus includes: a first holding unit configured to hold the plate member on the stage plate; a second holding unit configured to hold the plate member on the stage plate, allow relative deformation caused between the stage plate and the plate member in the first direction, and constrain the relative deformation in the second direction; and a third holding unit configured to hold the plate member on the stage plate, constrain the deformation in the first direction, and allow the deformation in the second direction.

Stage apparatus and microscope

There is provided a fuel cell including: a membrane electrode assembly including a polymer electrolyte membrane, an oxidizer electrode provided on one surface of the polymer electrolyte membrane, and a fuel electrode provided on another surface of the polymer electrolyte membrane; a first presser member arranged on a side of the surface on which the oxidizer electrode is provided; and a second presser member arranged on a side of the surface on which the fuel electrode is provided, in which, when the fuel cell is deformed, the fuel cell can be applied with a pressure in a laminating direction of the oxidizer electrode and the fuel electrode due to a stress generated by the first presser member and the second presser member.

Fuel cell and electronic apparatus on which the fuel cell can be mounted

A sheet material type detecting method for detecting a sheet material type has the steps of applying tension to at least a part of a sheet material, bounding an impact applying part on the part applied with the tension, a period detecting step of determining a period from a collision of the impact applying part with the sheet material to a specific state, and a sheet material identifying step of detecting a type of the sheet material based on the period.

Sheet material type detector

An image forming apparatus includes a recording sheet supplying portion for supplying a recording sheet and an image forming device for forming an image on the recording sheet supplied from the recording sheet supplying portion. A main power source supplies electric power to the image forming device and thermal fixing device. A recording sheet detector detects whether the recording sheet is present on the recording sheet supplying portion and a sub-power source supplies electric power to the recording sheet detector. A main power source switch automatically activates the main power source when the recording sheet detector detects the presence of the recording sheet or an image formation signal is inputted. The image forming apparatus does not include a main power switch to manually control the main power source.
