An imaging apparatus includes an imaging device that photoelectrically converts an optical image obtained through a focus lens. The focus lens is moved to a focus position set by focus detection performed based on image signals from the imaging device with a first aperture value. A first correction amount of the set focus position is acquired according to a difference between the first aperture value and a second aperture value to be used at a time of photographing. Photographing is executed at a determined focus position at the time of photographing, by a user's operation. If the first correction amount is larger than a predetermined amount, a focus position corrected according to the first correction amount is determined as the focus position at the time of photographing, and if not, the set focus position is determined as the focus position at the time of photographing.

Imaging apparatus having autofocus function, and focus adjustment method therefor

A bonding method using a bonding agent is provided, which has the steps of forming an underlayer on a first member, providing a bonding agent on the underlayer, forming a contact member, different from the bonding agent, on a second member, bringing the bonding agent into contact with the contact member so that the first member and the second member are bonded to each other. In the method described above, the wettability of the bonding agent to the underlayer is superior to that of the bonding agent to a surface of the first member before the underlayer is formed thereon, and the bondability of the bonding agent to the contact member is superior to that of the bonding agent to a surface of the second member before the contact member is formed thereon.

Manufacturing method of airtight container, manufacturing method of image display device, and bonding method

A joining material like an In film having a low melting point forms a surface oxide film when melted. If the oxide film is thick, an uneven surface shape will remain as it is, and can cause vacuum leakage during vacuum sealing. This problem is solved, for example, by placing particles of a refractory material inside the low melting joining material. The particles of the refractory material serve as a holding member for the low melting material and break the oxide film during a joining operation to bring the seal bonding with the low melting material to perfection.

Image display apparatus and production method thereof

In an image display device having in an airtight container an electron source and an image display member that receives electrons from the electron source, an evaporating getter and a non-evaporating getter are stacked in the airtight container. This makes it possible to maintain the vacuum level in the airtight container. The image display device thus obtains a prolonged life and a stable display operation.

Provided is an envelope which includes: a first substrate; a second substrate opposed to the first substrate; a frame interposed between the first substrate and the second substrate; and a low melting point metal for bonding the first substrate and the frame to each other. In particular, in such a configuration, the substrate or the frame has a first region and a second region which are brought into contact with the low melting point metal, and in the first region, a material capable of higher maintaining airtightness with the low melting point metal than the second region is in contact with the low melting point metal, while in the second region, a material having a stronger binding power on the low melting point metal than the first region is in contact with the low melting point metal.

In a pen-input computer or the like, it is impossible to distinguish an input method and to execute a proper process according to the input method. A touch panel driver generates finger-input coordinate values for a display screen. A digitizer driver generates pen-input coordinate values for the display screen. A processor receives the coordinate values and additional information indicative of either the finger-input or the pen-input from a source discriminator, starts an inputting process according to the input method, and allows a virtual keyboard to be displayed onto the screen or allows a &ldquo;CHR input pad&rdquo; window to be opened.

Information processing apparatus and its method

An influence by a vibration which is transmitted in the air is reduced, thereby preventing an erroneous detection of coordinates or a deterioration in a detecting precision. An elastic resin sheet is arranged on a coordinates input surface side of a vibration transmission plate so as to have a gap between the resin sheet and the vibration transmission plate and is fixed by an adhesive layer. When coordinates are inputted by a vibrator pen, namely, when a vibration is inputted, the resin sheet is warped by a writing pressure of the vibrator pen and the resin sheet comes into contact with the vibration transmission plate. Therefore, the vibration applied by the vibrator pen is efficiently transmitted to the vibration transmission plate. On the other hand, a vibration transmitted from the air is reflected by the boundary on both surface sides of the resin sheet and by the surface of the vibration transmission plate by a difference between acoustic impedances, so that the vibration entering the vibration transmission plate is remarkably reduced.

In the coordinate detection of resistive film system, detection of the coordinates of simultaneously designated two points is made possible. On a touch panel composed of two conductive films, whether input is made in a point or simultaneously at two points is judged by a current monitor. Simultaneous inputs at two points decrease the apparent resistance of the conductive film, and can be detected by an increase in the current. If the input of a point is identified, the coordinate data of the input point are retained as latest coordinate data in a RAM. If simultaneous inputs at two points are identified, coordinate data are obtained from the coordinate data retained in the RAM and from the potentials in the x and y directions, obtained from two conductive films constituting a touch panel, through amplifiers, and are outputted, together with the coordinate data retained in the RAM, as the coordinate data of the two points.
