Abstract: To provide a method for manufacturing zeolite membrane that has characteristics of being resistant to the reaction for a long time and in the high-temperature range, and has characteristic of long-duration hydrogen generation. The inventors of the present invention successfully produced a highly dense zeolite membrane by the steps of: evacuating the surface of porous support not adding the zeolite seed crystals dropwise, thus densely filling the seed crystals in the micropores; and applying hydrothermal treatment to the seed crystals. In addition, the inventors of the present invention confirmed that the zeolite membrane manufactured by the above methods has the characteristic of generating hydrogen for a long time.

Abstract: An indicator for a connector, which is attached to a connector, has a first indication member at which is indicated first information urging a user to perform a predetermined operation before using the connector, and which is attached to a position such that the connector cannot be connected if the user does not remove the indicator for a connector, and which can be removed from the connector. The indicator for a connector also has a second indication member at which is indicated second information which is useful at a time of connecting the connector, the second indication member being attached to a position which does not impede connection of the connector.

Abstract: A digital camera, in which power supply to a display screen constituted by an LCD is ON/OFF-controlled, is disclosed. When drive power is supplied to the LCD, an object image is displayed on the LCD based on image data obtained by image pickup, and the LCD is used as a viewfinder in photographing. At this time, when a period, in which the level of the brightness of the object image expressed by a luminance signal of the image data is less than a predetermined level, continues for a predetermined period or longer, the supply of the drive power to a display system including the LCD is controlled to stop the supply of the drive power and save power consumption.

Abstract: A used digital camera is purchased by a shop from a user. The shop checks whether the digital camera operates normally. When the digital camera operates normally, product data thereof is sent to a sales management server of a manufacturer through the Internet. The sales management server searches for the model of the digital camera on the basis of product data, and extracts model information. A label with the product information of the digital camera is glued on a packing box corresponding to the model. The packing box with the label is sent to the shop. The used digital camera is sold to another user after packing in the packing box. An operation manual corresponding to the model may also be sent to the shop.

Abstract: When the interior of the electronic camera is seen from the back side, a battery is arranged at the part corresponding to the inside of a grip part arranged at the right side of the casing so that the long axis of the battery is along the right side of the casing, and an imaging part including a taking lens and a CCD is arranged at the upper left. Below the imaging part, an LCD monitor and a memory card holder are arranged parallel to a plane perpendicular to the optical axis of the taking lens. In this arrangement, the components of the camera are arranged in a compact size. On the back face of the camera body, a mode dial is arranged at a position that can be operated by the thumb of a hand holding the grip part. The mode dial is capable of rotating within a plane perpendicular to the optical axis of the taking lens.

Abstract: A package for receiving and storing a camera and corresponding accessories for display, the package including a main body provided with a first camera cavity portion and an accessories cavity portion separated from one another. The camera cavity portion being for accommodating a camera, and the accessories cavity portion being for accommodating accessories for the camera. A protective cover superposed with the main body having a camera second cavity portion for protecting a camera when it is in the first camera cavity portion. The protective cover extends over the accessories cavity portion. First projecting portions are formed at a rear surface of the main body at positions near an outer periphery. The projecting portions for supporting the package in an upright free-standing state and a second projection portion on a front surface protective cover surrounding the camera cavity portion.

Abstract: A cartridge comprises a shutter for opening and closing an opening portion formed on a ceiling plate of an upper side member. The shutter slides on an outer surface of the ceiling plate by attaching and detaching the cartridge. Lifter projections are projected on a back portion of a lifter provided in the cartridge. The lifter projections are projected to an outer section through an opening portion formed on a bottom plate of a lower side member. If the cartridge is put on the plane, the lifter projections are pressed to an interior, so that the lifter is pushed up. Thereby, a recording paper is pressed onto the back surface of the ceiling plate. As a result, a space of the cartridge is lessened, the flow of air from the outer section is reduced, and a variation in internal moisture is controlled.

Abstract: A waterproof case for a camera comprises a case body, which contains the camera, and a lid, which is hinged to the case body and closes an opening of the case body watertightly. The hinge connecting the lid to the case body is provided with a friction member that holds the lid stationary at an arbitrary opening angle or at a predetermined opening angle regardless of the weight of the lid. The waterproof case is provided with a camera attachment member and a coil spring for moving the camera contained in the case body to a predetermined position as the lid opens. It is therefore possible to easily exchange recording mediums, and replace and charge a battery in the camera without taking the camera out completely from the case body.

Abstract: An outer case of a VTR integrated with a camera is formed to provide a substantially flat rectangular parallelepiped, so that the VTR becomes compact in size and has excellent portability. A shortest dimension of the parallelepiped-shaped case, an optical axis of the lens, and a shortest dimension of the video cassette tape are substantially parallel to a line pointing to a subject being recorded on video tape. During the engaging operation of a taking button, a thumb of a right hand supports the outer case from the rear surface thereof against a pushing force of the taking button. That is, the operation of pushing the taking button is the same as the operation of clamping the outer case between a thumb and a forefinger, so that no camera shake is caused during the operation of the button.

A detecting claw (66) is disposed to project from an inside to an outside of the receiving wall. The detecting claw is pressed by the outer wall and moved from the projected state to the retracted state. A terminal cover (60) is disposed on the receiving wall in a position covering the second pair of terminals and in movable fashion between the covering position and an uncovering position of uncovering the second pair of terminals. The terminal cover is pressed by the battery pack and moved from the covering position to an uncovering position.
