An analog electronic timepiece is an analog electronic watch capable of displaying a plurality of types of calendar information, and includes a first index adapted to indicate the type of the calendar information, and a second index adapted to indicate a value of the calendar information of the type indicated by the first index.

Timepiece

A timepiece movement includes a battery housing section configured and arranged to house a primary battery and a secondary battery unit in a replaceable manner.

Electronic timepiece and secondary battery unit

The electronic timepiece has an external case; a time indicating section that indicates the time; a solar panel; and a battery housing section that is provided in a main plate, a positive side contact terminal that is electrically connected to a positive supply terminal of the indication controlling section and configured such that the positive side contact terminal can be brought into contact with a positive terminal of a battery housed in the battery housing section; a negative side contact terminal that is electrically connected to a negative supply terminal of the indication controlling section and configured such that the negative side contact terminal can be brought into contact with a negative terminal of a battery housed in the battery housing section; and a contact section is positioned such that the contact section is not in contact with a battery housed in the battery housing section.

A magnetic core portion, a residual base material portion, and a connecting portionare formed by pressing from a base material. NotchesA are formed at a peripheral edge of the magnetic core portion, which is bent in the direction of the plate thickness to form a temporary fixing portion. When base materialsare overlapped to cut the magnetic core portionsfrom the connecting portion, the magnetic core portionsare pressed in directions toward one another so that the temporary fixing portionis filled between notchesA in the other magnetic core portion, to fix temporarily the other magnetic core portions. Since the magnetic core portionsare temporarily and simultaneously fixed by pressing in a cutting step normally carried out, the magnetic core portions can be temporarily fixed with ease.

Method of manufacturing magnetic head

It is possible to display high quality images by reducing or preventing heat accumulation in an electro-optical device, reducing or preventing undesired force from being applied to the electro-optical device due to the expansion and contraction of a mounting case, and reducing or preventing dislocation of the electro-optical device in the mounting case. The electro-optical device having an image display region, on which projection light from a light source is incident light, is encased in the mounting case constituted of a plate and a cover. One of the plate and the cover includes a resin member to fix the electro-optical device to the mounting case and a metal member including a window corresponding to the image display region in the electro-optical device.

Electro-optical device, projection display apparatus, and mounting case

An electro-optical device encased in a mounting case having an image display region, on which projection light from a light source is incident, includes a mounting case including a plate disposed to face one surface of the electro-optical device and a cover to cover the electro-optical device, a portion of the cover abutting against the plate, the mounting case accommodating the electro-optical device by holding at least a portion of the peripheral region located at the circumference of the image display region of the electro-optical device with at least one of the plate and the cover. Then, at least one of the plate and the cover being bonded to the electro-optical device.

Electro-optical device encased in mounting case and projection display apparatus

The invention provides an electro-optical device that displays high quality images regardless of temperature circumstances of the surroundings. The electro-optical device can be encased in a mounting case which accommodates a liquid crystal panel in which projection light is incident on an image display region from a light source. The mounting case can include a plate arranged so as to face one surface of the liquid crystal panel, a cover arranged so as to cover the plate and the liquid crystal panel, an adhesive for attaching the plate to the liquid crystal panel, and adhesive pockets provided in at least one of the plate and the cover, for accommodating the adhesive.

Electro-optical device encased in mounting case, projection display apparatus, and mounting case

The invention provides a technique to effectively cool an electro-optical device in the electro-optical device encased in a mounting case. The mounting case can include a plate member arranged so as to face one surface of a liquid crystal panel and a cover member arranged so as to cover the plate and the liquid crystal panel. Cooling-air guiding portions that include at least some of the side surfaces of the liquid crystal panel as at least some of the surfaces that constitute the passage can be provided in the cover member.

The invention provides a cased electro-optical apparatus that can include an electro-optical unit that receives light in the image display area from a light source, a plate that opposes one side of the electro-optical unit, and a cover for covering the electro-optical unit. The cased electro-optical apparatus can have a case for containing the electro-optical unit by supporting at least a portion of the periphery of the image display area of the electro-optical unit by the plate and/or the cover. One of the plate and the cover is selected from a plurality of ones having different shapes and each of the plurality of ones is attachable to the other.

Liquid crystal projector with different shaped housing for each liquid crystal panel dependent on color

An electro-optical device cased in a mounting case includes an electro-optical device having an image display region on which projection light from a light source is incident, and a mounting case including a plate disposed to face one surface of the electro-optical device and a cover to cover the electro-optical device, a portion of the cover abutting against the plate, the mounting case accommodating the electro-optical device by holding at least a portion of a peripheral region located at the circumference of the image display region of the electro-optical device with at least one of the plate and the cover. In addition, the cover includes a cooling air introducing portion, and the cooling air introducing portion having a cooling air guiding portion to allow the cooling air which is blown to the electro-optical device encased in the mounting case to flow toward the image display region.

Container for projector display panel

Electro-optical device fixed to mounting case by cover that includes resin and metal member

Provided is an electro-optical device encased in a mounting case including an electro-optical device having a substrate in which projection light from a light source is incident on an image display region, and a mounting case including a plate disposed to face one surface of the electro-optical device and a cover to cover the electro-optical device, a portion of the cover abutting against the plate, and the mounting case accommodating the electro-optical device by holding at least a portion of the peripheral region positioned at the periphery of the image display region of the electro-optical device with at least one of the plate and the cover. Also, the plate has a coefficient of linear expansion within a predetermined range on the basis of the coefficient of linear expansion of the substrate.
